GUATEMALA CITY (Reuters) – A fish that lives in mangrove swamps(紅樹沼澤) across the Americas can live out of water for months at a time, similar to how animals adapted(適應(yīng)) to land millions of years ago, a new study shows.
The Magrove Rivulus, a type of small killifish, lives in small pools of water in a certain type of empty nut or even old beer cans in the mangrove swamps of Belize, the United States and Brazil. When their living place dries up, they live on the land in logs(圓木), said Scott Taylor, a researcher at the Brevard Endangered Lands Program in Florida.
The fish, whose scientific name is Rivulus marmoratus, can grow as large as three inches. They group together in logs and breathe air through their skin until they can find water again.
The new scientific discovery came after a trip to Belize.
“We kicked over a log and the fish just came crowding out,” Taylor told Reuters in neighboring Guatgemala by telephone. He said he will make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at time, while lungfish found in Australia, Africa and South America can live out of water, but only in an inactive state. But no other known fish can be out of water as long as the Mangrove Rivulus and remain active, according to Patricia Wright, a biologist at Canada’s University of Guelph.
Further studies of the fish may tell how animals changed over time.
“These animals live in conditions similar to those that existed millions of years ago, when animals began making the transition(過渡) from water onto land,” Wright said.
1. The Mangrove Rivulus is a type of fish that _______.
A. likes eating nuts
B. prefers living in dry places
C. is the longest living fish on earth
D. can stay alive for two months out of water
2. Who will write up a report on Mangrove Rivulus?
A. Patricia Wright.
B. Scott Taylor.
C. Scientists from Belize.
D. Researchers in Guatemala.
3. According to the text, lungfish can ________.
A. breathe through its skin
B. move freely on dry land
C. remain alive out of water
D. be as active on land as in water
4. What can we say about the discovery of Mangrove Rivulus?
A. It was made quite by accident.
B. It was helped by Patricia Wright.
C. It was based on a lab test of sea life.
D. It was supported by an American magazine.

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid, T. Bower designed a method for projecting an optical illusion(視覺影像)of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements. All the 16-to 24- week -old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted(替換)a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week -old babies did not seem to notice the switch(更換). Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.
68. The passage is mainly about _____.
A. babies’ sense of sight                 B. effects of experiments on babies
C. babies’ understanding of objects         D. different tests on babies’ feelings
69. In Paragraph 3, “object permanence” means that when out of sight, an object ________.
A. still exists    B. keeps its shape        C. still stays solid       D. is beyond reach
70. What did Bower use in his experiments?
A. A chair.        B. A screen.      C. A film.         D. A box.
71. Which of the following statements is true?
A. The babies didn’t have a sense of direction.
B. The older babies preferred toy trains to balls.
C. The younger babies liked looking for missing objects.
D. The babies couldn’t tell a ball from its optical illusion.

For those who are conditioned to think that learning only happens in a classroom, the world of self-learning can be a little daunting. How do we best take   1  of these new opportunities?
Your interest in the subject is the essential driver of success. You can’t learn what you do not want to learn. Emotion is an important part of the learning   2  . If you are even moderately interested in a subject, give yourself  a chance. The key is to get started. If you can create some pleasurable   3 , you may find that the subject grows on you.
Don’t expect to understand things, much less remember them, the first time you study them. Trust that things will get clearer   4  your brain comes to grips with new information. It is like a cross-word puzzle. As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but    5   its own schedule. Learning does not take place according to a schedule laid down by a curriculum or teacher. Some things are easier to learn than others. Some things just take    6  to click in. Keep at it, and you will gradually find that things that seem difficult at first , will become easy with time.
Your brain is struggling to form patterns to    7   new input from your learning activities. Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up. If you are stuck, move   8  . Then cover the same general information from a different source, a different book, or a podcast, or an online lecture or a video. Try to become a  grazing learner, roaming the countryside,     9  a feedlot learner, just standing there in one spot. The broader your base, the easier it is to learn. Just as the “rich get richer”, the more you know,     10  you can learn.
Take full advantage of the Internet, iTunes, and     11  mobile devices, not to mention good old-fashioned books and magazines. Learn during “dead time”. Listen in your car, on the train, or   12  jogging. Have your learning with you while waiting in the doctor’s office, or listen while checking out at the supermarket. Anytime is     13 time. Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a    14  , rather than building a brick wall.
The more varied your learning content, and the more varied the ways in which you learn, the       15 the puzzle will become. Different learning activities suit different people, at different times of the day. Vary your activities in order to keep your interest level   16   . Even if listening and reading work best for you, treat yourself to the odd video lecture, or get-together with other learners. This will renew your batteries.
The “l(fā)oneliness of the distance learner” is a thing of the   17 . Join a learning communityon the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning style. You will find encouragement, advice and stimulus from fellow learners,        18   from tutors, teachers and coaches. In these communities, you can measure your progress against your own goals, or compare your experience     19   that of other learners. You can even teach and help others, which is a great way to learn.
Never has it been easier nor more exciting to be a learner. Let constant learning be a major part of your life-style. The   20       will be constant, personally, socially, and professionally.

Indians Refuse Higher Education
On June 17,1744, the officials from Maryland and Virginia held a talk with the Indians of the Six Nations. The Indians were invited to send boys to William and Mary College. In letter the next day they refused the offer as follows:
We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are certain that you mean to do us good by your suggestion; and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be displeased if our ideas of this kind of education happen not to be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces:
They were taught all your sciences; but, when they came back to us, they were bad manners, and they knew little of every means of living in the woods... they were totally good for nothing.
We are, however, not the less obliged for your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a dozen of their sons, we will take care of their education, teach them in all we know, and make men of them.
59.The passage is about _______.
A.the talk between the Indians and the officials
B.the colleges of the northern provinces
C.the educational values of the Indians
D.the problems of the Americans in the mid-eighteenth century
60.The Indians’ chief purpose in writing the letter seems to be to______.
A.politely refuse a friendly offer
B.express their opinions on equal treatment
C.show their pride
D.describe Indian customs
61.Different from the officials’ view of education, the Indians thought______.
A.young women should also be educated
B.they had different objects of education
C.they taught different branches of science
D.they should teach the sons of the officials first
62.The mood of the letter as a whole is best described as ______.

"It takes an entire village to raise a child." That's an old proverb (諺語) that is being quoted more and more often these days. And I'm pleased about that.
Today, more and more schools are reaching out to involve parents, community members and businesses(工商企業(yè))to help shape a child's future.
Parents need to be involved in their children's education in many ways. Helping children with homework and studying, going on a field trip, teaching a craft(手工藝)or coaching a child's sports team are all great ways to be involved with your child's education. And don't forget to communicate with teachers ---- they need and respect your input. Studies show that children learn more and schools function better when parents and schools work together. It's important to stay in touch with your child's education all through his or her school career.
Communities can help children create and achieve new goals. Help with homework, read to a child, coach a children's team, or provide emotional(情感上的)support. Help solve problems and build self-esteem(自尊心). Kids need role models and advisers can be role models by sharing their experiences and wisdom.
Businesses can also help shape our children's future. Invite a class from your local school to visit your workplace. You may be providing a glimpse that opens a new world of possibilities. Show students what goes on during a typical day. Give a mini course for students: how to use a computer; how products are made; how machinery works. You may have a developing electrician, teacher, nurse, or even a newspaper reporter on your hands.
It really does take an entire village to raise a child.So share the responsibility(職責(zé))-- and the joy -- of bringing a child to his or her full potential(潛能).
小題1:The implied advice in the proverb "It takes an entire village to raise a child." is that ______.

In the last 500 years, nothing about people — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可樹)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Eu¬rope, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish peo¬ple starved when the crop failed during the "Potato Famine (饑荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.
1. according to the passage, which of the following has changed the most in the last 500 years?
A. Food.     B. Clothing.          C. Ideology.           D. Language.
2. The word "some" in the last sentence of the first paragraph refers to________.
A. some cocoa trees                  B. some chocolate drinks.
C. some shops                          D. some South American Indians
3. Thousands of Irish people starved during the " Potato Famine" because________
A. they were so dependent on potatoes that they refused to eat anything else
B. they were forced to leave their homeland and move to America
C. the weather conditions in Ireland were not suitable for growing potatoes
D. the potato harvest was bad
4. according to the passage, which of the following statements is NOT true?

A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts. 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 an synoptic picture(氣象圖) of conditions in the atmosphere at a given time.?
All students of geography should 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, droughts and all climate 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 outlooks are based on an analysis of the upper air levels.?
With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(氣象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.?
小題1: Which is not mentioned in this passage in the following about one characteristic of weather?
A.Fronts.B.Temperature change.C.Wind speed.D.Frost.?
小題2:The observation of weather conditions by satellites is advantageous because
_______.
A.it is modern and sophisticated?
B.it used electronic instruments?
C.it enables man to alter the weather?
D.it gives the scientists information not obtained readily otherwise?
小題3:The word “interpret” in Paragraph 2 most probably means _______
A.explainB.presentC.modifyD.illustrate

Among the dead in South Asia’s tsunami were many tourists at Sri Lanka’s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and flee to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater rupture likely produced sound waves known as infrasound or infrasonic sound. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration. The massive quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves move on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached SriLanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yale might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears. Humans have a lot of things on our minds and usually that works out OK.
Notes:
①    tsunami  n. 海嘯
②    infrasound  n. 次聲
③    vibration  n. 振動(dòng),顫動(dòng)
Choose the best answers according to the above:
小題1: Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?
A.Because the animals were staying at a higher place in the park.
B.Because the animals were able to run much faster than human beings.
C.Because human beings cannot hear the infrasonic sound.
D.Because the animals might have picked up the danger signals and ran away.
小題2:Which of the statements about “Ravleigh waves” is true?
A.Rayleigh waves are massive vibrational waves that usually cause quakes or tsunamis.
B.Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.
C.Rayleigh waves can be felt both by animals and human beings.
D.Rayleigh waves, just like infrasonic sound, can only be felt by animals.
小題3:When a tsunami hits, it is possible that____.
A.we can’t feel the infrasound so we can’t be informed of the danger
B.we can feel Rayleigh waves as well as infrasound so we are able to escape the danger like animals
C.we were so busy with things on our minds that we feel neither infrasound nor Rayleigh waves
D.we think nothing of the information of its coming even though we can also get it
小題4: What does the underlined word “that” in the last sentence refer to?
A.Screening out the information.
B.There being so much going on before our eyes and in our ears.
C.Having a lot of things on our minds.
D.Paying attention to the information.
