Rats eat our food or make it so dirty that it isn't fit for people at all. That's why people often kill them by laying down poison. After a day or two, they find the poison still there. The rats haven't touched it, even though it is near the food which they eat. People think they must be clever and cunning. Some scientists have been trying to find the best way to poison rats. They have watched to see just what a rat does day and night. They have found out that rats aren't so clever. They are just very shy.

　　Rats usually live in holes. They run from these holes to the places where they eat and drink. They have special paths on which they travel each time. So they know their paths quite well.

　　If anything new, such as stone or wood, is put in the path, the rats won't go near it at first as they are too frightened. It will take them many days to get over the fear. They are also frightened to go near a place that they know, where something has been taken away. If a path goes around a rock, the rats follow the same path around the rock each time. If the rock is taken away, they will still run round the place where the rock was! They won't cross the empty place, which is now open to them, even though it would be quicker.

　　Rats will always keep away from anything unusual to them. That's why they won't eat poison on the first or second night. They usually won't go anywhere near it for about four days until they get used to being there. Even then they only eat a little at a time.

　　If people want to kill rats with poison, all they have to do is to leave it out for a few days. Once the rats have got used to it, they will eat it and die.

閱讀下列短文，完成文后題目。

　　Part A

　　In 2001 the United Kingdom was hit again by foot-and-mouth disease, the first time since the 1960s, causing a national crisis. However, much of the panic and confusion was spread largely as a result of ignorance of the disease.

　　Foot-and-mouth is a highly contagious(傳染性的) disease found in Africa, South America, Asia, the Middle East and parts of Europe. It affects cloven-footed (偶蹄) domestic animals such as cows, pigs, sheep and goats, as well as wild animals like rats and deer and zoo animals such as elephants. Horses, however, cannot contract(感染) the disease.

　　It is very rare for humans to catch the disease Indeed, only one case has been recorded in Great Britain and that was in 1967.

　　Part B

　　Foot-and-mouth disease is insidious(潛伏的)and can be spread by direct or indirect contact with infected animal. The disease can be spread on the wind, and can also be spread by people, equipment or vehicles which have been in contact with the disease.

　　Although the authorities do not really know where this latest outbreak of the disease originated, it can enter a country in frozen meat imported from other countries where the disease is common. Unlike Mad Cow Disease (BSE) and the human equivalent CJD, foot-and-mouth has no implications(牽連) for the human food chain. Any meat, milk, cheese and other dairy products can be consumed quite safely.

　　Part C

　　It seems that the only way to contain the disease is to kill infected animals. There is no cure for the disease, and although adult animals normally recover in 2-3 weeks, they sadly remain carriers of the virus (病毒) for up to two years.

　　From the time the disease was first reported to the time the epidemic (流行) was officially declared over, one and a half million and more domestic animals were slaughtered and large areas of the countryside were closed to the public. These areas included parks, woods and forests, and various leisure attraction situated in the countryside.

1．The main purpose of writing this text is ________.

[　　]

A．to warn people of the danger of the disease

B．to describe the disaster caused by the disease

C．to share some of the facts about the disease

D．to declare the success in control of the disease

2．Foot-and-mouth disease is insidious because it is spread ________.

[　　]

A．by farmers and farm vehicles

B．in so many different ways

C．by being carried in the air

D．mainly by people who have been in contact with infected animals

3．How is foot-and-mouth different from Mad Cow Disease?

[　　]

A．It affects the human food chain.

B．People cannot consume dairy products.

C．It is found in frozen meat.

D．Meat is still safe to eat.

4．The, underlined word“they”in Part C refers to ________.

[　　]

A．diseases
B．infected animals
C．a(chǎn)dult animals
D．2－3 weeks

閱讀理解:閱讀下列短文, 從所給的四個選項中, 選出最佳答案。 

    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　　 (證實) that rats will, when given a choice over a period of time,　　 prefer water with vitamins (維生素) 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 (轉(zhuǎn)) 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 (飲食).

　　

　　     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　　 響) 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
