Researchers from the University of Michigan have found that astronauts’ brains change shape during spaceflight. It is the first study1.(look) into how the brain changes in space. Researchers looked at high-tech MRI(磁共振成像)pictures of the brains of 26 astronauts who spent time in space. Twelve of the2.(astronaut) spent two weeks on the Space Shuttle, and 14 spent six months on the International Space Station. All of them3.(experience) increases and decreases in the size of 4.(differ) parts of the brain. The longer an astronaut spent in space ,the 5.(big) the size differences were.

The research produced some6.(interest) findings. One was that on gravity means fluids do not drop in the body, 7.there is a shift in the brain’s position inside the skull. The brain becomes either smaller or bigger. The findings could help doctors to treat problems that affect the brain’s function. They could treat people with problems 8.(cause)by long-term bed rest. They could also help those who have a build-up of fluid in the brain, which can lead9.brain damage. We will understand more about 10.neurons(神经元)in the brain connect. The findings will also help future trips to Mars.

A minister was on a long flight from China to London. The first warning of the approaching problems came when the sign on the airplane flashed on: Fasten your seat belts. Then, after a while, a calm voice said, "We shall not be serving the drinks at this time as there is going to be something unexpected. Please be sure seat belt is fastened."

Soon the storm broke out. One moment the airplane was lifted on terrific currents of air. The plane dropped as if it were about to crash.

The minister believed that he shared the discomfort and fear of those around him. As he looked around the plane, he could see that nearly all the passengers were upset and alarmed. The future seemed ominous and many were wondering if they would make it through the storm. Then he suddenly saw a little girl. Apparently the storm meant nothing to her. She was reading a book and everything within her small world was calm orderly. Sometimes she closed her eyes and then she would read again. Then she would straighten her legs, worry and fear were not in her world. The minister could hardly believe his eyes.

It was not surprising therefore that when the plane finally reached its destination and all the passengers hurried to leave, the minister walked up to the girl he had watched for such a long time. Having commented about the storm and the behavior of the plane, he asked why she had not been afraid. The girl replied, "Because my dad is the pilot, and he's taking me home."

To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey（猎物）, meeting mates and protecting themselves. A web-building spider without its web is like a man cast away on an island of solid rock, totally out of touch and destined to starve to death.

So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier（憔悴的）, it constructs a wider-meshed web using fewer strands（线）. Such webs would only trap larger prey, which is more economical from the perspective of a starving spider.

The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactively, labeled materials, it was found that 95 percent of web protein reappears in the next day' web. Most of the energy needed for web-building is used in walking over the strands as they are laid down．

Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate（无脊推动物）. If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another.

1.What is probably the best title for the passage?

A. Secrets of Spiders' Adaptability

B. Secrets of the Spiders' Life

C. Importance of Webs to Spiders

D. Spiders' Highly Preprogrammed Brain

2.According to the passage, which of the following statements is TRUE?

A. Web-building spiders will probably die without their webs.

B. One Web-building spider usually conducts one web.

C. Most spiders will stop conducting webs when hungry.

D. Web-building spiders have good eyesight.

3.A spider conducts a wider-meshed web when ________.

A. it is 16 days old

B. it is getting weaker

C. it has fewer wends

D. it hunts for food

4.A spider's ability to finish an incomplete web proves that ________.

A. it reuses its web protein to reproduce new silk

B. it is able to rebuild a destroyed web

C. the incomplete web is much more important

D. it has a highly preprogrammed brain

Learning new cultures is one of my favorite things to do.

College is a time for new and exciting experiences as well as a time to explore diverse and innovative(创新的)ideas. What could be better than traveling to China to learn about their ideas, history, and culture? I believe studying abroad is something that every college student should do to help to expand his or her horizons, and to appreciate everything the world has to offer. I spent the first eight of my early years living abroad in two countries. From this rich period of growth, I acquired an identity as a global citizen, and the skills to independently navigate life in a foreign culture. It seems appropriate to support my next jump in life with an abroad experience that will show the directions in which I have grown since my early years, as well as provide a unique context for exploring the limits of my education.

Here is an undeniable advantage to living and studying in China; to be submersed in (投入)the Chinese life is the only way to fully understand and learn about how the country impacts and is impacted by the rest of the world. Not only am I learning about China, but I have also come to appreciate other countries in the world from a different point of view. Being in China has given me the change to learn in a different environment, and I do not think there is any better way to learn the culture than to actually be there. I have a very strong admiration for the Chinese language, people, and culture. I will continue to apply my newfound knowledge to my entire life and the way I look at the world around me.

1.What does the author say about studying abroad?

A. College can be barrier to study abroad

C. Not every college student suits for studying abroad

D. Studying abroad can enrich the experiences of living abroad

2.What did the author benefit from living abroad?

A. Skills to live independently

B. All nationalities of the world

C. Growing to be a strong person

D. Unlimited education chances

3.What does the author advise students to do about learning foreign cultures?

A. Learn foreign cultures locally

B. When in Rome, do as the Romans do

C. Appreciate cultures from different point of views

D. Try to impact foreign cultures with their own ones

Have you ever suddenly felt that someone you know was in trouble——and he was? Have you ever dreamed something that came true later? Maybe you have ESP（超感官知觉）.

ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events（事件）before they happen, or events that are happening some distance（距离）away.

Here is an example: A woman was doing washing. Suddenly she shouted, “My father is dead! I saw him sitting in the chair!” Just then, a telephone came. The woman’s father had died of a heart illness. He died sitting in a chair.

There are thousands of stories like this on record. Scientists are studying them to find out what is behind these strange mental（心理的）messages. Here’s another example——one of hundreds of dreams that have come true.

A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “There’s room for one more.” The man felt the driver was Death, so he ran away. The next day the man was getting on a crowded bus. The bus driver said, “There’s room for one more”. Then the man saw the driver’s face was the same face he had seen in the dream. He wouldn’t get on the bus. As the bus drove off, it crashed and burst into fires. Everyone was killed!

Some people say stories like these are lies or coincidences. Others say that are ESP in true, From studies of ESP, we may some day learn more about the human mind.

1.ESP lets people know about _________.

A. their dreams

B. events after they happen

D. heart illness

2.In his passage the word “coincidences” means ________.

A. things which do not happen
