Passage Three
The year is 2501, and Earth is desperately short of fuel. All Earth's coal, oil and wood have been used up long ago, and (18) (scientists) have been sent to the ends of the universe in search of alternative forms of energy.
Human scientists have been sure for a long time that Jupiter possesses a method of creating constant energy and now ten explorers on a secret mission from Earth have discovered the secret—(19) (a kind of heavy dust which will change salt water to high grade petroleum.) This dust covers a large part of Jupiter's surface, and just a few pounds of it could solve the world's energy crisis since it would reproduce itself continuously in Earth's atmosphere.
Questions 18 to 20 are based on the passage you have just heard.
18. BQ: Who have been sent to the ends of the universe in search of alternative forms of energy?
19. AQ: What's the secret the ten explorers discovered on Jupiter?
20. DQ: Which of the following statements is the main idea of the passage?
Section C
The computer is widely used in all (21) (phases) of society. Today the computer is used in the home, small offices, large (22) (corporations), and universities, and for manufacturing (23) (practically) everything a person may think of. It brings about great (24) (convenience) and high (25) (efficiency,) thus (26) (releasing) a vast number of man-hours to be used in other efforts.
During the past five (27) (decades) the computer has been rapidly advanced. (28) (What once required a very large room for bulky computer equipment can now be carried by a person in the briefcase and be operated everywhere.) Personal computers are very common today in high schools, business and even in some Chinese families. (29) (They are used for many things which were preciously done by hand.)
The computer must be instructed and programmed by people. (30) (Therefore, the information extracted from the computer is only as good as what people feed into it.) If incorrect instructions are given, then incorrect reports or documents will be received from it. When manufacturing an engine part by computers, for example, the instructions must be exact, because once improperly tooled, the part may not be useful.
