Passage TwoWhen 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 nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.People who are nearsighted 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 (角度). To prove this to yourself, look at an object out of one eye; then look at the same object outof the other eye. You will find the object's relation to the background (背景) 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 distance as people with two eyes.40. We should take good care of our eyes ______.A. only when we cannot see perfectlyB. only when we can see wellC. even if we can see wellD. only when we realize how important our eyes are
Dear Sirs,The order mentioned above was delivered to our warehouse 2 days after it arrived in Chicago 8th Jan. and we regret that we have to complain about the conditions in which we received it.In our order we stipulated that we required four dozen of your men's suits pattern CS/7, and in your invoice, No. CP/78, you charged us for this quantity, but it is clear that you have packed only three dozen in Case 3, 【B1】______ . We would therefore appreciate an explanation and your prompt action to send us the missing dozen suits.Very much more serious is the condition of the ladies' trousers suits that you packed in Case 2. Of the six dozen that this case contains, 【B2】______ . It is quite clear that this is solely due to the totally inadequate way in which they had been packed for you had not lined the case with any waterproof paper. 【B3】______【B4】______ , whereas in our order we had stated that we required your pattern CS/9 which is stated in your catalogue as being made up from heavy-weight material. There is no market here for tropical suits, and so we must emphasize 【B5】______ .We must stress that the mistakes that you have made in this first order we have placed with you have caused considerable problems for us. We had hoped to include your products in the Spring Sale that is due to open at the end of February, but as it is, it is now clear that we shall not be able to do so.

共用题干Weight on and off the Earth We are so used to.our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted.Because we can feel that things are heavy,we think of "weight"as being a fixed quality in an object,but it is not really fixed at all.If you could take a one-pound packet of butter 4,000 miles out from the earth,it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space?The reason is this:all objects have a natural attraction for all other objects;this is called gravitational attraction.But this power of attraction between two obects gets weaker as they get farther apart.When the butter was at the surface of the earth,it was 4,000 miles from the center.When we took the butter 4,000 miles out,it was 8,000 miles from the center,which is twice the distance.If you double the distance between two objects,their gravitational attraction decreases two times two.If you treble the distance, it gets nine times weaker(three times three)and so on. So this is one of the first things we need to remember that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon?At the distance the puii of the earth is about 4,000 times smaller than it is here on the surface,so we can forget all about the earth-pull on our butter. On the other hand,on the moon there will be an attraction between the butter and the moon,but the butter will weigh only about one-sixth as much as it does on the earth.This is because the moon is so much smaller than the earth.The amount of gravitational pull that a body produces depends on the amount of material in it.A packet of butter has a gravitational pull of its own;but this is very small in relation to the pull of something as large as the moon,or the earth,or the sun.According to the passage,"weight"should be understood in the sense thatA:it is fixed if it is outside the earth's gravitational puliB:it decreases four times when it is 4,000 miles from the earth's centerC:it varies with the change of the gravitational attraction between two objectsD:things increase in amount as they are closer to the earth's surface

问答题Practice 6 There are poor teachers, to be sure, and I’m convinced the teaching profession in this country must police itself more vigorously. I’ve thought sometimes that an incompetent teacher is worse than an incompetent surgeon, since a surgeon can cut up only one person at a time. However, it is also true that no profession is made healthy by focusing only on what’ s bad, and we must begin to see teachers as part of the solution, not the problem. Perhaps we can learn something from Japanese here. Teachers in that country are heroes of the culture. If we do so, we may come closer to identifying the reason for the differences in school performance in our two countries.
