五、Reading Comprehension (4×5’)
Directions: After reading the following passage, make the correct choice.
A computer is a machine designed to perform work mathematically and to store and select information that has been saved in it. It is run by either mechanical or electronic means. These machines can do a great deal of complicated work in a very short time. A large computer, for example, can add or subtract nine thousand times a second, or divide five hundred times a second. Its percentage of error is about one in a billion digits. It has been estimated that human beings making calculations average about one mistake per two hundred digits.
The heart of an electronic computer lies in its vacuum tubes, or transistors. Its electronic circuits work a thousand times faster than the nerve cells in the human brain. A problem that might take a human being two years to solve can be solved by a computer in one minute, but in order to work properly, a computer must be given instructions and it must be programmed. Computers can be designed for many specialized purposes. They can be used to prepare patrols, guide airplane flights, direct traffic, even to play chess. Computers play an important role in automation
process in plants and factories throughout the world.
1. A computer is a machine designed to ______________________.
A. perform work mathematically
B. perform complicated calculations
C. store and select information
D. all of the above
2. The speed with which an electronic computer works depends on its ________________
A. electronic circuits
B. programmer
C. vacuum tubes or transistors
D. instructions
3. According to the passage, computer play an important role in __________________
A. automation processes
B. mathematical computations
C. traffic control
D. the development of mathematical theory
4. The use of computers for specialized purpose depends on the ___________________
A. design of the computer
B. power used to operate the computer
C. difficulty of the mathematical calculations involved
D. the ability of the programmer
5. The passage implied that human beings differ from computers in that human beings ______________
A. make fewer mistakes
B. do not have to be programmed
C. work more quickly
D. understand their instructions

三、1、The drive train is generally composed of a clutch, a transmission, a
universal transmission, a final drive, a differential, and a half shaft. 2、The
function of the brake system is to slow down or bring to rest a moving
vehicle in a shortest possible distance, or to hold the vehicle stationary
if already halted.
