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 curefor 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,
how
ever, may take about ten years to develop. So at the same time, use your head—protect it!B. make connections only to other cells in the brain
C. can cure Lou Gehrig"s disease
D. are a person"s memory
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 disease
B. comparing it to other parts of the brain
C. telling how it got its name
D. explaining what it does
B. disorders
C. memories
D. messages

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! |

| 2. How do you feel during the first stage of culture shock? |

| 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 wha  tever 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 |
