C
Can you train your cat to actually use your toilet? Can you not have to deal with litter boxes any more? Well for many people the answers to these questions are yes.
You may have heard that some people have managed to train their cats to use the human toilet, Well this is correct.One advantage to this is the fact that you no longer have to lug heavy bags of litter home from the supermarket, or worry about cleaning out the dirty litter everyday.
Like any other cat training program, training your cat to use the toilet takes times and patience, you just can put your cat on the toilet and hope that they can use it.
By slowly shaping your cat’s behavior over a couple of weeks, you too can end lugging heavy bags of cat litter home from the supermarket.First, start by slowly moving the litter box closer and closer to the toilet each day, so your cat gets used to being in the bathroom and being around the toilet.
Next, when you have had to litter box next to the toilet for several days, slowly raise the litter box higher and higher each day until it is at the level of the toilet.Then find an insert for the top of the toilet, like a shallow pan that can sit in the rim of the toilet and hold litter.
Once your cat gets used to using this litter pan on top of the toilet for a week or so, try removing the pan and your cat should be able to use the toilet.
Like any cat training program, it takes time and effort on the part of the cat owner to do this.Don’t get frustrated with your cat if she is not learning as fast as you would like, many cats learn at their own pace.With a little effort you too can have a toilet trained cat.
64.The author advises you to train your cat to use a toilet so that may    .
A.keep the toilet clean
B.keep the cat clean
C.save a lot of trouble
D.save a lot of money
65.According to the passage, cat toilet training is a     process.
A.quick                     B.Complicated            C.difficult           D.gradual
66.When you have managed to get your cat to use the toilet, the litter box    .
A.is no longer needed                B.is still needed
C.should be kept where it is                 D.should be put back where it was
67.We can see from the passage that“a shallow pan”(in Para 6 )    .
A.is used instead of the litter box               B.is used to protect the cat
C.helps to raise the litter box             D.helps to clean the toilet

  The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小說(shuō)), but it is actually being taken seriously by many researchers.
  This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美國(guó)宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multi?billion?dollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物學(xué)). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
  But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大氣). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.
  But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said, “This is just wrong.”
5. The passage is about________.
A. a plan turning Mars into a little earth
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
6. Which of the following is NOT the reason why some scientists are against the plan?
A. The project would wipe out all the native lifeforms on the Mars.
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed. 
7. We can infer from the passage that________.
A. water is a crucial factor for life
B. the project will have little effect on the native lifeforms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
8. Which of the following supports the conclusion of microbes living in the Mars’s soil?
A. Scientists found liquid water in the Mars.
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.

C
Our brains work in complex and strange ways.There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two.Others can perform complex classical piano pieces after hearing them once, but they cannot read or write.
Dr.J.Langdon Down first described this condition in 1887.He called these people idiot savants.An idiot savant is a person who has significant mental impairment (損傷) , such as in autism or retardation.At the same time, the person also exhibits some extraordinary skills, which are unusual for most people.The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory.
One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr.Benjamin Rush, an American doctor.His patient, Thomas Fuller, was brought to Virginia as a slave in 1724.It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds.Despite this ability, he died in 1790 without ever learning to read or write.
Another idiot savant slave became famous as a pianist in the 1860s.Blind Tom had a vocabulary of only 100 words, but he played 5 ,000 musical pieces beautifully.
In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly.
Today we more clearly recognize that the idiot savant is special because of brain impairment.Yet not all brain impairment leads to savant skills.Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills.However few people wish to participate in such experiments.There are many excellent reasons for not undergoing unnecessary experimentation on one's brain.The term idiot savant is outdated and inappropriate.Virtually all savants have a high degree of intelligence and are thus not idiots.
63.What does the passage mainly talk about?
A.Idiot savants have areas of outstanding abilities.
B.Human Beings have complicated thinking process.
C.The brains of the idiot savants are partly impaired.
D.The reasons why people have wonderful skills vary.
64.Which of the following can be done by Rain Man?
A.He can play wonderful pieces of classical music.
B.He can guess out exactly the length of a man's life.
C.He can memorize the contents of the pictures fast.
D.He can count matches dropped on the floor quickly.
65.What can you infer from the passage?
A.Idiot savants have real talents for art and math.
B.Dr.Down is the first person who found idiot savants.
C.Few people wish to risk becoming savants by brain operations.
D.Intentional left brain impairments will surely lead to idiot savants.
66.Which of the following shows the structure of the passage?

1—5refer to paragraph 1—5.

Many do-it-yourself homeowners are interested in
trying out solar power to leam about the technology and
perhaps to provide energy for limited-use applications.
There are a variety of ways to find cheap solar panels
(板), including buying used and building your own
with factory seconds.Both methods will save money
while forcing you to learn the ins-and-outs of a solar
power array (陣列).  
We've all seen solar-powered street signs or PV
panels being used for various purposes at remote locations.
When those units become cracked or chipped and are considered "unsafe", companies are forced to replace them, generally to avoid responsibility issues.Because it's difficult to get rid of PV panels, many companies, if approached, are willing to give them away or to sell them for modest prices.Depending on the degree of damage present, expect to see performance degradation (降級(jí)) in the range of 10% to 60%.A multimeter (萬(wàn)用表) can be used to test the panel before buying.If the panel's free, take it anyway.It could still be useful in a home solar project.
A solar panel is really nothing but a box serving as a container for a large group of solar cells.Factory second solar cells are usually sold on eBay at a small part of their regular cost.The cells come in a variety of sizes.You will need to figure out how much power a single cell produces to determine how many will need to be wired together to form an array.
A simple search of the Internet will show numerous sites detailing home solar panel projects.Do-it-yourself lovers are generally quite generous in supply photographs of their work and description of what went wrong and right with the project.
Getting cheap solar panels with slight imperfections, either used or through sales of factory seconds, is a perfect solution for home-built renewable energy projects.The high number of solar lovers online provide a wealth of useful information.Only limited skills are required, plus an understanding of the basic wiring involved.All are well within the talents of almost any home handyman.Beyond the satisfaction of having completed the project, you'll come away with a functional solar panel that will be a source of power for use around the house or at remote locations.
Solar energy systems are quickly becoming more popular with homeowners as prices continue to decline.
72.The author writes the passage to introduce ____.
A.ways of finding cheap solar panels B.ways of saving energy
C.a(chǎn) way of making a solar panel     D.a(chǎn) home-built energy system
73.What does the phrase "factory seconds" in the passage refer to?
A.Second-hand factory products.  B.Cheap but perfect factory products
C.Faulty factory solar cells.        D.The second best factory solar cells
74.From Paragraph 5, we can learn about home-built energy projects that ____.
A.none of them are beyond home handymen
B.a(chǎn) lot of useful information is available on the Internet
C.a(chǎn) perfect solution is to get cheap and perfect solar panels
D.understanding electrical wiring is not necessarily needed
75.What is the author's attitude towards the future of solar energy systems?
A.Optimistic.  B.Pessimistic.      C.Indifferent.         D.Doubtful

PART THREE  READING COMPREHENSION
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage. (20%)
A
“Mummy, I don’t know what to play with. ” Steve interrupts his mother, who is talking to a friend, for the fourth time. “You’ve got a room full of toys!” his mother says, impatiently, In fact it is the jumble of toys which is to blame for four -year-old Steve's lack of interest in his dolls, cars and stuffed (packed)animals. Each morning he tips out three washing baskets of toys all over his floor, listlessly pulls out something and shortly after is standing at his mother’s desk or following her into the kitchen saying: “Mummy, I am bored.”
A family therapist(治療專(zhuān)家)explains why children lose interest when they have a whole “toy shop” at home : “According to their brain development, little children are not in a position to judge the quality of a variety of things at once. There is always just one favorite toy for the moment. All the rest is left lying about.” What can parents do to stop their children from being oversupplied with toys? Under no conditions simply make something disappear without the child’s knowledge. If he/she takes no more notice of a toy, a parent can ask if it can be stored or given away. Be warned though the child will help. Lyn is the mother of four-year-old Jessie, and holds the toys and books that are the current(at present)favorites. When it seems to her that her daughter is tired from a cupboard in another room. The box of “old” toys goes into the cupboard. When her child says she is “bored”, they also get something from her cupboard—it may be something she has had for some time but because she hasn’t seen it for a while it is almost like a new toy.
  Some favorite toys stay out all the time, and there is collection of dolls which sits in the comer, but in this way Lyn has found that she has fewer toys to put away at the end of the day and her daughter always has something “fresh” to play with.
66. Steve interrupted his mother several times because________.
  A. he felt uninterested in his toys              B. he disliked his mother’s guest
  C. he didn't have enough toys to play with        D. he hoped his mother would play with him

  A. they can’t play alone for a long time
  B. they are too young to play with so many toys
  C. they are too lazy to pick out their favorites
  D. they lack the ability to value too many things at a time
68. Which of the following can be used in place of the underlined word “jumble ”?
  A. Simple choice.                          B. Mixture in disorder.
  C. Ordinary appearance.                    D. Same shape.
69. Which is the advice given to parents in the text?________.
  A. Buy fewer toys for their children        
B. Form good habits for their children
  C. Spare some time to play with their children   
D.Put some toys away without telling their children

In many societies, there is often greater acceptance of light skin than dark skin.Light skin may be seen as a mark of beauty, intelligence and success.These beliefs can lead to social pressure even within the same racial group.As a result, more and more people with dark skin are using skin-lightening products, even if they may face health risks.
Many people believe that having whiter skin will improve their lives.They think they will have a better chance of getting a job or marrying into a better family.Or they want to look like what their society generally considers beautiful.
Some beauty care products contain chemicals that make skin lighter.This process is also called bleaching (漂白).But some of the chemicals are extremely dangerous.One chemical has been linked to kidney (腎) damage and some kinds of cancer.It also causes low birth weight in babies when used by mothers-to-be.
At first, bleaching products make the skin color lighter.But after long-term use they can cause problems.The chemicals in the products block and break down the natural process that gives color to skin.The skin loses its natural barrier to protect against sunlight.Then the skin can become thick and discolored.Usually the person will use more of the product in an effort to correct the problem, but this only makes it worse.
Fatimata Ly treats skin problems in the Senegalese capital, Dakar.Doctor Ly says skin bleaching has become a problem throughout Senegal.She says the chemicals are now more dangerous because they are stronger.Some cases have resulted in blackened fingernails, infections and permanent skin damage.
And these are not the only risks.Experts say some people who change their skin color suffer emotional damage.They feel regret and sadness.They feel that instead of risking their health, they should have learned to love and accept their skin color as it was.
72.Why has skin lightening become popular all over the world?                          
A.There are many ways to help change skin color.                     
B.Many people with dark skin have no confidence.                     
C.Light skin seems to bring more advantages than dark skin.                          
D.People with dark skin are facing the pressure from their family.
73.According to the passage, people using bleaching products would risk _____             
A.thinner skin             B.low weight      
C.lung cancer       D.emotional damage
74.Which of the following is NOT true about bleaching products?                        
A.Some of them contain dangerous chemicals.                   
B.They will not make the skin color lighter.                    
C.They may cause skin damage.    
D.They are likely to bring health risks.
75.The writer's attitude toward using bleaching products is ________.

Let’s do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday,you slept in,getting four extra hours.On Monday morning,you were feeling so bright—eyed that you only had one cup of coffee,instead of your usual two.But don’t be cheated by your energy.You’re still carrying around a heavy load of sleepiness,or what experts call “sleep debt”一in this case something like six hours,almost a full night’s sleep.
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It’s a shortage that grows every time we skim some extra minutes off our nightly sleep.“People get more sleep debt gradually without being noticed,”says William C.Dement,founder of the Stanford University Sleep Clinic.Studies show that such short term sleep lack leads to a foggy brain,worsened vision,and trouble remembering.Long-term effects include obesity(肥胖),insulin(胰島素)resistance,and heart disease.A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year.
The good news is that,like all debt,with some work,sleep debt can be repaid.Adding all extra hour or two of sleep a night is the way to catch up.For the long-term lack of sleep, take it easy for a few months to get back into a natural sleep pattern.
Go to bed when you are tired,and allow your body to wake you in the morning(no alarm clock allowed).You may find yourself catatonic(有緊張癥的)in the beginning of the recovery cycle:expect to have ten hours shut—eye per night;As the days pass,however,the amount of sleeping time will gradually decrease.
So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better.“When you put away sleep debt,you become a superman,”says Stanford's Dement,talking about the improved mental and physical capabilities that come with being well rested.
53.If you have short-term sleep lack,you may___________.   
A.put on weight    B.get heart disease  C.hate eating food   D.have a poor sight
54.The example of sleep math is used to show______.
A.in what case you build up a sleep debt
B.in what way you can make up for lack of sleep
C.why you are energetic even without enough sleep
D.why you need six hours’sleep every night
55.By saying the underlined sentence,Dement means that______.
A.you need a lot of sleep to be a superman
B.you will be in a good state with enough sleep
C.you need to be a superman to repay sleep debt   
D.you will become a superman with more sleep debt
56.What might be the most suitable title for the passage?   
A.How can you keep energetic?    B.What is sleep debt?
C.Can you catch up on lost sleep?  D.Can coffee refresh you?

C
LONDON: What could possibly be wrong with planting trees? The benefits are obvious; they  firm the soil, soak up (攝取) extra water and take carbon dioxide (二氧化碳) our of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly that the complexity of the system and the importance of not tinkering(粗劣地修補(bǔ)) with it without understanding the results. For this reason the need is to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超過(guò)) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again.
Solutions to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.
63.People usually hold the opinion that       .
A.huge dust storms can destroy carbon dioxide
B.huge dust storms can destroy the oceans on the earth
C.huge dust storms can’t do anything beneficial for man
D.planting trees is the only way to control huge dust storms
64.Andy Ridgwell, the environmental scientist, believes that       .
A.dust plays a more important part than trees
B.trees should’t have been planted in dry places
C.carbon dioxide is harmful to everything on the earth
D.environmental problems are more complex than expected
65.Robert Jackson’s experiment proves that         .
A.grassland areas should be covered by forests
B.trees hold more carbon than grasses
C.carbon can turn grass into dust
D.less carbon can make trees grow faster
66.The underlined word “combat” in the last paragraph means      .
A.learn about      B.fight against     C.live with   D.give up

科目:高中英語(yǔ) 來(lái)源:不詳 題型:閱讀理解

A university math tutor has discovered the science behind “singledom”, finding that our chances of finding the perfect partner are just 1 in 285,000. Peter Backus, a tutor at the University of Warwick, published his “Why I Don’t Have a Girlfriend” paper after a three-year love drought.
His unconventional study uses a famous math formula called The Drake Equation(德雷克等式), which was first used to estimate the existence of extra-terrestrial(地球以外) life.
The results don't look promising for British singles. 30-year-old Mr. Backus found that out of the 30 million women in the UK, only 26 would be suitable girlfriends for him.
The dull equation takes into account the number of women aged 24 to 34, living in his home city of London, and who are single, meaning his chances of meeting his dream woman on a night out are slim.
The economics expert said: “There are 26 women in London with whom I might have a wonderful relationship. So, on a given night out in London there is a 0.0000034% chance of meeting one of these special people. That’s a 1 in 285,000 chance, so it’s not great.”
The puzzling Drake equation reads: N =" R*" x Fp x Ne x Fi x Fc x L, and helped pioneering scientist Professor Drake to predict that there could be 10,000 civilizations in our galaxy.
Mr. Backus simply replaced the original equation with his own criteria for a dream date, which included the percentage of women likely to find him attractive, and the number of girls aged 24-34 in London. He said: “The research may sound depressing to people looking for love, but the good news for singles is, it’s probably not your fault!”
56. Mr. Backus’ discovery in this passage is mainly concerned about ______.
A. whether there exists life out of our planet
B. the possibility of his being able to find love
C. how to get rid of singledom
D. what math can do to serve our daily life
57. What does Mr. Backus think of the result of his research?
A. Optimistic.     B. Depressing.      C. Unrealistic.     D. Exciting.
58. What can we learn from the first paragraph?
A. Mr. Backus’ major research field is “singledom”.
B. Mr. Backus found a girlfriend three years ago.
C. Mr. Backus’ new thesis will surely be well received.
D. Mr. Backus has been searching for love for long.
59. By “the good news for singles” in the last sentence, Mr. Backus probably mean _____.
A. you don’t have to blame yourself for remaining single  
B. maybe the discovery is not reliable at all
C. the result was based on his own criteria
D. there might be more dream date out of London
60. Which of the following statements is true?
A. This passage could be published in a scientific magazine.
B. The passage intends to prove there are other civilizations.
C. The passage writer doesn’t really understand the Drake equation.
D. Most women in London are not suitable for university teachers.
