Passage Five

The Northern Pike is a very bad fish. It is a big, hungry fish, and swallows little fish such as trout and perch. Many Northern Pikes live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike are a serious threat to the lake because they eat all the smaller fish. Soon, all other species of fish in the lake will be killed off. This is not healthy for the environment.

Experts are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.

For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They haw. tried using nets, explosives and poisons. However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poi- sons are bad for humans who use the water. No trace of the poisons has ever been found in local wells, however.

Scientists are going to try the poison again. This time, they will drain the lake before they add the poison to the water. A public hearing will be held to talk about the problem.

52. Why are some people against the use of poisons to kill Northern Pike？

A. Fishermen will be poisoned too.

B. The poisons are expensive.

C. They think that wells will be polluted.

D. The lake will become unsafe.

Passage Five

In order to learn a foreign language well, it is necessary to overcome the fear of making mistakes. If the primary goal (目标) of language use is communication (交际), then mistakes are secondary considerations that may be dealt with gradually. On the other hand, students should not ignore their mistakes. The language learner may observe how native speakers express themselves, and how native expressions differ from the way the learner might say them. For example, a Spanish speaker who has been saying "I do it" to express willingness to do something in the immediate future, could, by communicating with native speakers of English, observe that native speakers actually say "I'll do it". The result can serve as a basis for the student to change his way of using the present tense in English. But a student who is unwilling to communicate in the first place would lose this opportunity to learn by trial and error.

52. According to the passage, the present tense in English is ______.

A. not used to express one's readiness to do something in the immediate future

B. used with some verbs but not with others to express future intention

C. basically the same in English as it is in Spanish

D. not the most difficult problem for foreign students

Passage Five

Roman soldiers in some places built long rows of signal towers. When they had a message to send, the soldiers shouted it from tower to tower. If there were enough towers and enough soldiers with loud voices, important news could be sent quickly over distance.

In Africa, people learned to send messages by beating on a series of large drums (鼓). Each drum was kept within hearing distance of the next one. The drum beats were sent out in a special way that all the drummers understood. Though the messages were simple, they could be sent at great speed for hundreds of miles.

In the eighteenth century, a French engineer found a new way to send short messages. In this way, a person held a flag in each hand and the arms were moved to various positions representing different letters of the alphabet (字母表). It was like spelling out words with flags and arms.

Over a long period of time, people sent messages by all these different ways. However, not until the telephone was invented in America in the nineteenth century could people send speech sounds over a great distance in just a few seconds.

51. According to this passage, the Roman way of communication depended very much on______.

A. fine weather

B. high tower

C. the spelling system

D. arm movements

Directions: There are five reading passages in this part. Each passage is followed by five

questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blackening the corresponding letter on the answer sheet.

Passage One

Artificial flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking skill and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artists-naturalists, Leopold Blaschka and his son Rudolph.

The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed, it contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models ate kept in locked cases, as they are too valuable and fragile for classroom use.

31. Which of the following is the best title for the passage？

A. An Extensive Collection of Glass Flowers.

B. The Live Leopold and Rudolph Blaschka.

C. Flowers Native to the United States.

D. Materials Used for Artificial Flowers.

Ⅳ. Reading Comprehension (75 points)

Directions: There are five reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blacken the corresponding letter on the answer sheet.

Passage One

Early in November 1965, New York was blacked out by an electricity failure (停电). The Mayor promised that it would not happen again. Pessimists (悲观主义者) were certain that it would happen again within five years. In July 1977, there was a repeat performance which produced a serious disorder throughout the city. At that time the city was in one of its worst heat waves.

In 1965, there was little crime during the darkness, and fewer than a hundred people were arrested. In 1977, hundreds of stores were broken into and looted (劫掠). Nearly 4,000 people were arrested but far more disappeared into the darkness of the night. The number of policeman available was far from enough and some looters even carry guns.

Hospitals had to treat hundreds of people cut by glass from shop windows. Banks and most business remained closed the next day. The blackout started at 9:30 P.M., when lightning hit and knocked out supply cables. Many stores were thus caught by surprise. For twenty-four hours, New York realized how helpless it was without electricity.

31. According to the first paragraph, who were right: the authorities or the pessimists？

A. The authorities.

B. The pessimists.

C. Both.

D. Neither.
