阅读理解     Scientists have found that human eyes are more likely to be damaged by UV rays
(紫外线) while skiing in the snow-covered areas than sitting on the beach, according to a report by the
UK newspaper The Telegraph.
     The researchers at Kanazawa Medical University, Japan and American company Johnson conducted
the study together. They looked at the effects of light reflection on newly fallen snow on a ski trail (a
rough path) in Ishikawa District, northern Japan. They compared the results with the levels of UV rays
on a sand beach in southern Japan"s Okinawa District. They found that on the beach, eyes are exposed
to a daily 260 kilojoules (千焦耳) of UV a square meter compared to 658 kilojoules in snow-covered
areas.
     The findings are supported by the Japan Meteorological Agency. According to the agency, the
reflection rate of UV light on beaches is often between 10 and 25 percent, compared to 80 percent in
the new snow areas. The amount of light increased 4 percent with a 300-meter rise in height.
     Most of us know that UV rays can harm the skin. That"s why we wear sunscreen on our skin before
we get out in the sun. But many of us may not realize that UV rays are also harmful to the eyes.
     If your eyes are exposed to large amounts of UV radiation over a short period of time, you may
experience a kind of sunburn of the eye, which is harmful. Your eyes will become red and feel a strange
feeling. They may be sensitive to light. Fortunately, this is usually temporary and seldom causes
permanent damage to the eyes.
     Long-term exposure to UV radiation, however, can be more serious. Scientific studies and
researches have shown that exposure to small amounts of UV radiation over a period of many years
increases the chance of eye damage, which could lead to total blindness.

1. You would most likely find the article in ________.

A. a medical magazine      
B. a travel journal  
C. a doctor"s diary
D. a physics textbook

2. Which of the following statements is TRUE according to the passage?

A. Too much eye exposure to UV rays may cause total blindness.
B. Short-time exposure of the eyes to UV rays doesn"t harm them at all.
C. Most people know that UV rays harm the eyes as well as the skin.
D. The study was conducted by researchers from Japan, the USA and the UK.

3. The underlined word "sunscreen" in Paragraph 4 most probably means ______.

A. sunglasses  
B. sun cream
C. sun hat    
D. sunburn

4. What will the passage most probably talk about next?

A. Never ski on newly fallen snow in Japan.
B. Take some measures to protect your eyes while skiing in new snow areas.
C. Wearing a hat can provide protection while skiing in new snow areas.
D. Go to hospital to have your eyes examined.

举一反三
     What are you doing right now? Yes, you are reading this page. That also means you"re moving your
eyes. You"re thinking. You"re breathing. You"re listening. Possibly you"re shifting(变换) positions. You"re
also feeling things—this book, your chair, emotions. What lets you do all these things at the same time?
Your brain.
     Your brain is the control center of your body and mind. Without your brainyou can"t do anything. Your brain has more than 100 billion nerve(神经) cells. Each nerve cell makes from 1,000 to 10,000
connections with other nerve cells. The nerve cells send impulses back and forth in your brain and to and
from every part of your body. After you reach the age of 20, though, your brain cells start to die. This is
common. However, if you suffer an illness, or injury, even more nerve cells die in your brain. When a
nerve cell dies, the thousands of connections it made with other nerve cells are lost.
     Until recently, scientists believed that the brain did not replace its dead cells. New studies, however,
prove not. Scientists have found new nerve cells in a part of the brain called the hippocampus(海马区).
The hippocampus helps the brain form memories from new experiences.
     The discovery of these new nerve cells is not a cure for anything yet. It gives hope, however, of a cure
for brain damage from such things as epilepsy(癫痫病), Lou Gehrig"s disease, car accidents, and strokes. Someday scientists might be able to use the new cells to replace damaged brain cells. Such a cure,
however, may take about ten years to develop. So at the same time, use your head—protect it!2. Nerve cells in the brain______.A. send massages to every part of the body
B. make connections only to other cells in the brain
C. can cure Lou Gehrig"s disease
D. are a person"s memory2. The last sentence of the passage suggests that people______.A. should use their head by carefully thinking through situations
B. should be careful not to injure their brains
C. have a skull (头盖骨) that provides all the protection needed by the brain
D. would see a quick cure for brain disease3. The author explains what the hippocampus is by ______.A. telling its history
B. comparing it to other parts of the brain
C. telling how it got its name
D. explaining what it does4. Nerve impulses are______.A. cures

阅读理解     In a new study about the way kids learn math in elementary school, Beilock and Levine found a
surprising relationship between what female teachers think and what female students learn: If a female
teacher is uncomfortable with her own math skills, then her female students are more likely to believe
that boys are better than girls at math.
     " If these girls keep getting math-anxious female teachers in later grades, it may create a snowball
effect on their math achievement," Levine told Science News. In other words, girls may end up learning
math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are
better at math than girls are, then these girls may not do as well as they would have if they were more
confident.
      The researchers also gave the students tests to tell whether the students believed that a math
superstar had to be a boy. Then the researchers turned to the teachers: To find out which teachers
were anxious about math, the researchers asked the teachers how they felt at times when they came
across math, such as when reading a sales receipt. A teacher who got nervous looking at the numbers
on a sales receipt, for example, was probably anxious about math.
     Boys, on average, were unaffected by a teacher"s anxiety. On average, girls with math-anxious
teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus, on the
test showing whether someone thought a math superstar had to be a boy, 20 girls showed feeling that
boys would be better at math - and all of these girls had been taught by female teachers who had math
anxiety.
     According to surveys done before this one, college students who want to become elementary
school teachers have the highest levels of anxiety about math. Plus, nine of every 10 elementary teachers
are women, Levine said.

1. Which of the followings is NOT the study mentioned in the passage?

A. Girls may be bad at math because of their female teachers" anxiety.
B. Most students tend to believe that a math superstar has to be a boy.
C. What kind of teachers is more likely to have math anxiety.
D. On average boys are also affected by a teacher"s anxiety.

2. What can you infer from the second paragraph?

A. Girls can do as well as boys if they are confident.
B. Girls are born much weaker than many boys.
C. Boys are stronger and better in math than girls.
D. Girls who are bad at math can do other things better.

3. According to the last paragraph, Levine"s imply attitude to the math teaching in elementary schools
    is _______.

A. hopeful
B. disappointed
C. worried
D. content

    Psychologists tell us that there are four basic stages that human beings pass through when they enter and live in a new culture. This process, which helps us to deal with culture shock, is the way our brain and our
personality react to the strange new things we encounter when we move from one culture to another.
    Culture begins with the "honeymoon stage". This is the period of time when we first arrive in which
everything about the new culture is strange and exciting. We may be suffering from "jet lag" but we are
thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kind
s of food. This stage can last for quite a long time because we feel we are involved in some kind of great a
dventure.
    Unfortunately, the second stage can be more difficult. After we have settled down into our new life, we can become very tired and begin to miss our homeland and our family, friends, pets. All the little problems
in life seem to be much bigger and more disturbing when you face them in a foreign culture. This period of cultural adjustment can be very difficult and lead to the new arrival rejecting or pulling away from the new
culture.
    The third stage is called the "adjustment stage". This is when you begin to realize that things are not so
bad in the host culture. Your sense of humour usually becomes stronger and you realize that you are
becoming stronger by learning to take care of yourself in the new place. Things are still difficult, but you are
now a survivor!
  The fourth stage can be called "at ease at last". Now you feel quite comfortable in your new surroundings.
You can cope with most problems that occur. You may still have problems with the language, but you
know you are strong enough to deal with them.
     There is a fifth stage of culture shock which many people don"t know about. This is called "reverse (颠倒、交换)culture shock". Surprisingly, this occurs when you go back to your native culture and find that
you have changed and that things there have changed while you have been away. Now you feel a little
uncomfortable back home. Life is a struggle!
1. When does culture shock happen?
A. When you reach your teens
B. When you move to a big city
C. When you meet foreign people for the first time
D. When you go to live in a foreign culture
2. How do you feel during the first stage of culture shock?
A. Lonely and depressed  
B. Bored and homesick
C. Happy and excited  
D. Angry and frustrated
3. How could the third stage be described?
A. Adjustment    
B. Rejection      
C. Enthusiasm    
D. Anger
4. Why might reverse culture shock be a problem?
A. It hardly ever happens.            
B. It is extremely stressful.
C. Most people do not expect it.      
D. It only happens to young people.

    Education is not an end, but a means to an end. In other words, we do not educate children only
for the purpose of educating them. Our purpose is to fit them for life.
     In some modern countries it has for some time been fashionable to think that by free education for
all - one can solve all the problems of society and build a perfect nation. But we can already see that
free education for all is not enough; we find in such countries a far larger number of people with
university degree; they refuse to do what they think "low" work; and, in fact, work with hands is thought
to be dirty and shameful in such countries. But we have only to think a moment to understand that the
work of a completely uneducated farmer is far more important than that of a professor; we can live
without education, but we die if we have no food. If no one cleaned our streets and took the rubbish
away from our houses, we should get terrible diseases in our towns…
     In fact, when we say that all of us must be educated to fit us for life, it means that we must be
educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability
and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be
ashamed of one"s work. Only such a type of education can be considered valuable to society.

1. The writer of the passage thinks that _______.

A. education can settle most of the world"s problems
B. free education for all probably leads to a perfect world
C. free education won"t help to solve problems
D. all the social problems can"t be solved by education

2. The writer wants to prove that _______.

A. our society needs all kinds of jobs
B. our society needs free education for all
C. a farmer is more important than a professor
D. work with hands is the most important

3. The purpose of education is _______.

A. to choose officials for the country
B. to prepare children mainly for their future work
C. to let everyone receive education fit for him
D. to build a perfect world

4. The passage tells us about _______ of the education.

A. the means
B. the system
C. the value
D. the type
