　　It is hard to predict how science is going to turn out, and if it is really good science, it is impossible to predict．If the things to be found are actually new, they must be unknown in advance．You cannot make choices on this matter．You either have science or you don't and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits．

　　The only solid piece of scientific truth about which I feel totally confident is that we don't know enough about nature．Indeed, I regard this as the major discovery of the past hundred years of biology．It is, in its way, a clear piece of news．It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange seems the way ahead．In earlier times, they either pretended to understand how things worked or simply made up stones to give answers．Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered．Because of this, we are sorry．It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted．

　　But we are making a beginning, and there ought to be some satisfaction．There are probably no questions we can think up that can't be answered, sooner or later．Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention．

阅读理解:阅读下列短文, 从所给的四个选项中, 选出最佳答案。 

    Animals seem to have the sense to eat when they are hungry and　　 they do not eat more than their bodies need. It has been demonstrated　　 (证实) that rats will, when given a choice over a period of time,　　 prefer water with vitamins (维生素) to water without vitamins, even　　 though there is no difference in taste or smell between the two water　　 bottles. When a fragrant flavor (香味) was added to the　　 vitamin—enriched liquid, the rats did seem to develop a taste for it　　 and kept drinking it, even after the vitamins were switched (转) to　　 the clear water. In time, however, they broke the habit and went back　　 to where the necessary vitamins were.

　　

　　    In an experiment, babies of 6 to 12 months old were placed in a　　 cafeteria (自助食堂) with a wide selection of baby food before them.　　 They were given whatever food they pointed to or appeared interested　　 in. We are told that at first they showed some unusual eating　　 patterns, but over a period of time they managed to select a well　　 balanced diet (饮食).

　　

　　     So, in selecting food, rats and babies do seem to know and act on　　 what's best for them. Clearly, there is a kind of "body wisdom" which　　 humans soon lose. Most of us do not eat as wisely as we could. Many　　 of our food preferences are culturally determined and influenced (影　　 响) by long-established habits. Some people eat fox, dog and　　 blackbirds, while we eat cows and pigs. So what people eat and how　　 much they eat seems to be greatly influenced by what is going on　　 around them.　　

　　

(1)In the experiment on rats, a fragrant flavor was added to the　　 rat's drinking water to ________.

[　　]

A. encourage rats to drink it　　 　　

B. find out what kind of flavor rats prefer　　 　　

C. test whether rats know which drink is with fragrant flavor　　 　　

D. demonstrate that vitamins are tasteless　　 　　

(2)The expression "the habit" in the first paragraph refers to　　 drinking water which __________.　　　　　　　　　　

[　　]

A. has no smell　　 B. is tasteless

C. has vitamins　　 D. is flavored　　 　　

(3)As far as their eating habits are concerned, babies and rats　　 are similar (相似) because ___________.　　　　　　

　　

[　　]

A. both have the wisdom to choose a balanced diet　　 　　

B. both prefer flavored food and drink　　 　　

C. both have the same eating patterns　　 　　

D. both develop a taste for the same kinds of flavors　　 　　

(4)In the experiment mentioned in the second paragraph, babies　　 were _________.

A. given many choices of drinks　　 　　

B. provided with various kinds of baby food　　 　　

C. placed and fed in a cafeteria　　 　　

D. trained to select a balanced diet　　 　　

(5)According to the passage, adults' (成年人) eating habits differ　　 from those of babies because ____________.　　　　

　　

[　　]

A. adults know better than babies what kinds of food are good for their health　　 　　

B. adults usually cannot resist the temptation of various delicious foods　　 　　

C. adults' eating habits are closely related to the social and cultural customs　　 　　

D. adults have more choices of food than babies in eating patterns

     CBC is a famous air company which has over twenty planes carrying passengers and goods, flying
along 12 fixed lines all over the world. Its service is very good but some passengers are still not satisfied
with it and that is why in 1998 and 1999 the company received letters of complaints(投诉) from consumers
or passengers who pointed out over a dozen kinds of problems which are divided in groups in the following
table. This division is called Category. Problems that appear when the plane is flying are Flight problems.
Those about passengers' things carried by the plane are Baggage problems. Customer service refers to
service work which passengers are not satisfied with. Over sales of seats are about the fact that more seats
are sold and as a result the plane is too crowded to be safe. Refund problems appear when passengers fail
to receive the money paid to them because of what they have lost. Fares are problems about the price of
tickets. Reservations are problems that appear when passengers could not get the tickets they have already
booked. Tours are problems about the passengers'traveling by air or hotel problems. Advertising is what the
passengers think about advertisement on the plane. Credit problems are about the use of credit cards.
