Passage 1
Questions 1 to 5 are based on the following passage:
More than 30,000 drivers and front seat passengers are killed or seriously injured each year. At the speed of only 30 miles per hour it is the same as falling from a third-floor windows. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.
Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to ￡50. it will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.
However, you do not have to wear a seat belt if you reversing your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear you seat belt.(76) Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.

Passage 2
Questions 6 to 10 are based on the following passage:
The human brain contains 10 thousand million cells and each of these may have a thousand connections. (77)Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件) or by altering the architecture but that too will happen.
(78)I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon’s long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.
As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.
6. In what way can we make a machine intelligent?
A) By making it work in such environments as deserts, oceans or space.
B) By working hard for 10 or 20 years.
C) By either properly programming it or changing its structure.
D) By reproducing it.(C)
7. What does the writer think about machines with human-like ability?
A) He believes they will be useful to human beings.
B) He believes that they will control us in the future.
C) He is not quite sure in what way they may influence us.
D) He doesn’t consider the construction of such machines possible.(A)
8. The word “carbon” (Line 4, Para. 2) stands for ________.
A) intelligent robots B) a chemical element C) an organic substance D) human beings(D)
9. A robot can be used to expand our frontiers when ________.
A) its intelligence and cost are beyond question
B) it is able to bear the rough environment
C) it is made as complex as the human brain
D) its architecture is different from that of the present ones(A)
10. It can be inferred from the passage that ________.
A) after the installation of a great number of cells and connections, robots will be capable of self-reproduction
B) with the rapid development of technology, people have come to realize the possibility of making a machine with human-like ability
C) once we make a machine as complex as the human brain, it will posses intelligence
D) robots will have control of the vast, man-made world in space
Passage 3
Questions 11 to 15 are based on the following passage:
“... We are not about to enter the Information Age but instead are rather well into it.” Present predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related. In 1980, only twenty-one percent of all United States high schools owned one or more computers for student use.(79) In the fall of 1985, a new survey revealed that half of United States secondary schools have fifteen or more computers for student use. And now educational experts, administrators, and even the general public are demanding that all students become “computer literate (慢点…的).” “By the year 2000 knowledge of computers will be necessary in over eighty percent of all occupations. Soon those people not educated in computer use will be compared to those who are print illiterate today.”
What is “computer literacy”? The term itself seems to imply soon extent of “knowing” about computers, but knowing what. The current opinion seems to be that this should include a general knowledge of what computers are, plus a little of their history and something of how they operate.
Therefore, it is vital that educators everywhere take a careful look not only at what is being done, but also at what should be done in the field of computer education. Today most adults are capable of utilising a motor vehicle without the slightest knowledge of how the internal-combustion engine works. We effectively use all types of electrical equipment without being able to tell their histories or to explain how they work. (80)Business people for years have made good use of typewriters and adding machines, yet few have ever known how to repair them. Why, then, attempt to teach computers by teaching how or why they work?
Rather, we first must concentrate on teaching the effective use of the computer as the tool is.
“Knowing how to use a computer is what’s going to be important, we don’t talk about ‘automobile literacy. ‘ We just get in our cars and drive them.”
11. In 1990, the number of jobs having nothing to do with computers in the United States will be reduced to ________.
A) 79 million B) 30 million C) 70 million D) 100 million(C)
12. The expression “Print illiterate” (Para. 1, Line 16) refers to ________.
A) one who has never learnt printing B) one who is not computer literate
C) one who has never learnt to read D) one who is not able to use a typewriter(C)
13. The first paragraph is mainly about ________.
A) recent predictions of computer-related jobs B) the wide use of computers in schools
C) the urgency of computer education D) public interest in computers(C)
14.According to the author, the effective way to spread the use of computers is to teach ____.
A) what computers are B) how to use computers
C) where computers can be used D) how computers work(B)
15. Which of the following statements is FALSE?
A) What to teach about computers should be reconsidered.
B) Those who are not educated in computer use will find it difficult to get a job.
C) Human society has already entered the Information Age.
D) Those who want to use computers should know how computers operate.
