Passage Five The computer is a wonderful machine. It is the most important invention since the type of engine used in cars. Today it has the greatest effect on science, industry and business, but it is being used more in education and medicine. By the end of this century it will touch the lives of everyone, even people in distant villages. It is a revolutionary invention. The oldest kind of computer is the abacus, used in China since the sixth century. In the seventeenth century an adding machine was invented, but the first large, modern computer was built in 1973. A few years later a computer could do 5,000 additions per second. Now the computations are so fast that they are measured in nanoseconds. Today most computers are stored-program computers, that is, they have a memory. They are getting smaller and smaller, and computing faster and faster. Even in a large computer, the part that does the actual computing is about the size of the end of a finger. Computers can do a
A. prints the information

Passage Five When a teacher or lecturer recommends a student to read a book, it is usually for a particular purpose. In many eases, the teacher doesn’ t suggest that the whole book should be read. In fact, he may just refer to a few pages which have a direct bearing on the matter being discussed. Unfortunately, when many students pick up a book to read they tend to have no particular purpose in mind other than simply to "read the book". Often they open the book and start reading, page by page, line by line, word by word; in other words, slowly and in great detail. The result is that students frequently don’ t have an overall view of what they are reading; also, they tend to forget fairly soon what they’ ye been reading. Students can make their reading much more effective by adopting a strategy (策略) aimed at helping them to understand and to remember what they read. Firstly, they should decide precisely why they’ re reading the book: perhap
A. the importance of reading
B. the effective ways of reading
C. the difficulties in reading
D. the incorrect habits of reading

No one really expects a vacation trip to produce a close friend, but the beginning of a friend ship is possible. The word "friend" can be applied to a wide range of relationships--to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant(知己).
