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) out 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 taking in 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 final 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 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) 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.
小題1: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
小題2: Andy Ridgwell, the environmental scientist, believes that_____________.
A．dust plays a more important part than trees
B．trees shouldn’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
小題3: 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

In the 1960s Professor Bolin predicted that the “greenhouse effect”, caused by an increase in the amount of carbon dioxide (CO2) in the atmosphere, would lead to important changes in the Earth’s climate. At the time his prediction were regarded as science fiction. But it is now gradually agreed that the amount of carbon dioxide in the atmosphere will double from 0.03% to 0.06% in the next 50 years and that temperatures worldwide will rise by 2°Celsius.
Although a temperature rise of 2°may not seem significant, the local effects may be much greater: in polar regions a rise of 10°by 2025 is expected and in Northern Europe a rise of 4°. Indeed the first effects were expected to be felt before the end of the 20th century,
But how does the “greenhouse effect”operate and why should such a tiny proportion（比例）of CO2 have such a harmful effect? When living creatures breathe out or when things are burned, CO2 enters the atmosphere. Until recently all of this was absorbed by plants, which converted it back into oxygen.
However, the balance of nature has been disturbed. In power stations, in factories and in our cars, we are burning more and more fossil fuels( coal, oil and natural gas ) and this produces huge quantities of CO2---18 billion tons of it enter the atmosphere every year. Added to this, the destruction of forests means that less CO2 can be converted into oxygen by plants. So, the amount of CO2 in the atmosphere is increasing every year.
小題1:Which of the following statements is true according to the passage?
A．Professor Bolin’s predictions were taken seriously in the first place
B．Only a small portion of the atmosphere consists of carbon dioxide
C．No changes in climate will become noticeable for 50 years or more
D．The rise in temperature will probably be 2 degrees in every part of the world.
小題2:The amount of CO2 in the atmosphere is increasing every year because       .
A．Carbon dioxide is produced when we breathe
B．Carbon dioxide is produced when we burn things
C．More forests are destroyed and more fossil fuels are burned
D．The global temperature keeps rising
小題3:The “greenhouse effect”refers to         
A．the problem of the rising global temperature
B．the problem of increasing population worldwide
C．the problem of decreasing population worldwide
D．the problem of air pollution
小題4:The underlined word“operate”in the third paragraph most probably means“      ”.
A．playB．moveC．manageD．function

Your children’s teacher will be providing extra time for test preparation. This school year’s test will be held on January 8 and 9. The test preparation time is open to all students, and we strongly encourage your children to attend.
This year we are changing the time for our test preparation: it will be on Thursday mornings from 8:10 to 8:50. This helps children who ride the bus and cannot stay for the after-school period. It also helps avoid conflicts with after-school activities.
Danielle and Marina will be working with the recent new test takers 6 days on the following Thursdays: 15th, Nov; 29th, Nov; 6th, Dec; 13th, Dec.; 20th, Dec. and 3rd, Jan.
Besides the test preparation lectures on these dates, teachers are already putting test preparation into their usual courses. We are finding that we can help our students to be both skillful and whole-hearted readers and test takers — after all, we all know that the best test preparation is good reading and writing training.
What can you do at home? Again, the best and most effective test preparation for the ELA test is reading and more reading. The research is quite clear — students who do well in the tests are those who are good readers. Reading not only builds reading ability, it also helps build confidence — important for successful test taking! But do discourage your children from spending too much time on books that are too hard or even a bit too hard. Children best develop comprehension skills when they are reading books just right for them (too easy doesn’t hurt here either).
Finally, on Friday, December 7, we will have a morning lecture on the ELA. Please pay attention!
小題1:The text is mainly about ________.
A．how teachers will provide more time for test preparation
B．the reason why time for test preparation will be changed
C．how teachers have put test preparation into their usual courses
D．test preparation information that parents should know about
小題2:The time for test preparation has been changed to _________.
A．make it more convenient for the students to attend
B．help the new test-takers have more time to read
C．a(chǎn)void disagreement in time between different years of students
D．a(chǎn)void conflicts between preparation time and the usual courses
小題3:From the passage, we know that ________.
A．Danielle will help students prepare for different tests
B．the school year test will be on a Tuesday
C．a(chǎn)ll the children must take part in the test preparation
D．the students can learn how to write well in the test preparation
小題4: Parents should _____ at home.
A．prepare good meals for their children
B．read more books with their children
C．a(chǎn)sk their children not to spend too much time on reading
D．encourage their children to read more books fit for them
小題5:Why did the school encourage all the students to take part in the test preparation?
A．Test preparation is what they always do.
B．The students will learn what will be included in the final exam.
C．Test preparation helps students to be more interested in reading and confident.
D．The test is a long way off and there are better things to do.

An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (創(chuàng)造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思廣益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(織布機(jī)) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions!
小題1: In most cases, an invention ________ according to the first paragraph.
A．comes from a complete new idea
B．is usually based on an old product or idea
C．will change its creator’s life completely
D．is created by scientists in different fields
小題2:The second paragraph mainly wants to tell us _______.
A．the difficulty in making a new invention
B．the common steps of creating new things
C．having a good idea is the key to creation
D．designing a tool is the first step in inventing
小題3:The example of Chester Greenwood is used to show that ________.
A．children can also invent something
B．it is easy even for children to make inventions
C．kids have more advantages in inventing things
D．to be an inventor is the best way to change one’s life
小題4:At first Chester designed his earmuffs in order to ________.
A．protect his ears while ice-skating
B．earn money to support his poor family
C．realize his dream of becoming an inventor
D．make himself look fashionable while ice-skating

A weather map is an important tool for geographers.   A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts (氣鋒) to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity (強(qiáng)烈).They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a summary picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather map accurately.Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States  Weather Bureau issues information about approaching storms, floods, frosts and all climatic conditions in general. Twice a month it issues a 30-day"outlook" which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms.
Considerable effort is being exerted today to achieve more accurate weather
predictions, with identifying and tracking storms over regions which have but few meteorological (氣象)stations. Extensive experiments are also in progress for weathef modification studies.
小題1: One characteristic of weather maps NOT mentioned by the author in this passage is_______.
A．floodsB．frontsC．temperature changesD．frosts
小題2: The thirty-day forecast is determined by examining________.
A．daily weather mapsB．upper air levels
C．satellite reportsD．changing fronts
小題3:The observation of weather conditions by satellites is helpful because it________
A．is modern
B．uses electronic instruments
C．makes weather prediction easier
D．shows things that would otherwise take hours to describe in a few minutes
小題4:A weather map is a summary because it_______
A．sums up a great deal of informationB．a(chǎn)ppears daily
C．shows changing frontsD．is a science book

Friendships are some of the most important relationships that we will ever have in our lives. But how to build a solid friendship? Here are five tips for you.
Tip 1. _____
True friendships can only be built in honesty. This is more than just telling the truth. Being real and open about who you are and your thoughts and feelings are a part of building a solid friendship. If your “friends” don’t even really know you, who are they really friends with?
Tip 2. Shared Experiences
As you build your friendship, you will share many experiences together. Some of these may be great adventures or hard times that the two of you go through together. These shared experiences are things that you will laugh about, talk about, and cry about no matter how much time passes.
Tip 3. Sacrificial（犧牲精神的）love
Love is the basis（基礎(chǔ)）of all solid relationships. I am not referring to the emotion（情感） of love, but to the action of love. Love is what will cause a friend to get out of bed in the middle of the night to help another. Love is what will put aside someone’s own wants to make sure that their friend is alright.
Tip 4. Understanding
When a friendship is solid, it will be based on each other’s understanding. You may not agree with everything that a friend says or does, but you will be able to put yourself into his or her shoes to begin to understand. Offering understanding to a friend is very important, as it allows them to feel that they have someone in their corner that they can talk to and who will offer advice and suggestions, without having to worry that if they don’t always follow it, the friendship will be lost.
Tip 5. Acceptance
A solid friendship is one in which two people accept one another, faults and all, for just who they are. There is no having to build up false excuses, or hide away the “dark secrets” from one another. We accept each other as whole, complete, and totally unique people.
小題1:What’s the best title of Tip 1?
A．Introduction of yourself.B．Telling the truth
C．HonestyD．True friendships
小題2:Which tip can remind us of an English proverb “Love me, love my dog”?
A．Tip 2.B．Tip 3.C．Tip 4.D．Tip 5.
小題3:What’s the meaning of the underlined part “put yourself into his or her shoes” in Tip 4?
A．Exchange your shoes with his or hers.B．Try on his or her shoes.
C．Put yourself in his or her position.D．Force yourself.
小題4:What’s the best title of the whole passage?
A．A solid friendshipB．The most important relationships
C．Five tips for youD．Tips on how to build a solid friendship
