When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.
People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.
Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts（白内障）. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
When night falls, colors become fainter（不清楚） to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.
1.We don’t know that our eyes are of great importance until ________.
A. we think about our eyes B. we cannot see clearly
C. we wear glasses D. we have to do much reading
2.According to the passage, a ________ is more likely to be nearsighted.
A. student B. runner C. guard D. worker
3. People who are farsighted ________ .
A. cannot do a lot of close work without glasses
B. can only see things that are very close to their eyes
C. have difficulty reading a book if they hold it at arm’s length
D. have the same problem as the nearsighted people
4. To see a small thing at night, it is better to look ________ .
A. with wide open eyes B. with half shut or narrowed eyes
C. straight at it D. in a slightly different direction

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.
1.We should take good care of our eyes .
A.only when we can see well
B.only when we cannot see perfectly
C.even if we can see well
D.only when we realize how important our eyes are
2.The underlined word blurry in the second paragraph probably means .

Now, we know that if we do not get enough vitamins, we are at risk of developing a number of diseases. As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.
In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.
Experts, however, say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.
Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.
In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.
1.What is probably talked about before this passage?
A. How many vitamins a person’s body needs.
B. How many vitamins some foods contain.
C. The benefits that vitamins bring to our health.
D. What people should do to stay healthy.
2.Vitamin supplements are popular with people because ________.
A. people mistakenly think that they are good for their health
B. they contain more vitamins than the foods people eat
C. food does not provide enough vitamins people need
D. people fear that a lack of vitamins will lead to disease
3.From the passage, we can learn that medical experts advise people _________.
A. never to take any vitamin supplements
B. to depend only on food for their vitamins
C. not to take any vitamins together with medicines
D. to consult doctors before taking vitamin supplements
4.For people who lack Vitamin B-twelve, they can eat more from _______.

Many people think that personal development is something they can't do. 1. You might find a few new suggestions in this article.
A great way to help one's mood is to live in the here and now. The idea is similar to the idea in Eckhart Tolled The Power of Now. If you live in the present moment, you cannot ever possibly be in pain, because to know pain there has to be a past.
2. During hard times we tend to always think about what is troubling us and lose sight of the bigger picture. A faith helps one focus on that bigger picture while changing the focus from hardship to a higher power.
To help yourself, focus on helping others. 3. Do you view them as unique individuals who are worthy of respect, or do you just see them as obstacles（绊脚石）who are always getting in your way? The more you care about others, the more you will care for yourself.
When you are trying to improve yourself, it is important to remember to focus on one thing at a time. 4. This leads to frustration and eventually you may give up.
One of the most important things about self-improvement is to set achievable goals for yourself. Setting goals that are unreachable will only make you feel discouraged!
The information you just looked at should help you to feel more confident of your efforts to grow as an individual. 5.
A. God helps those who help themselves.
B. Pay attention to your attitudes towards others.
C. If you try to improve several different aspects, you may lose control of all of them.
D. But the truth is that everyone can help themselves personally develop.
E. Sometimes finding a faith to devote oneself to is a great self-help idea.
F. Keep a positive mindset（心态）, and apply your chosen tips consistently.
G. Being kind is always helpful to yourself.
