Then why am I able to write about computers? I can write on this subject because of these shortcomings. The last two years of learning has been a hard test for me. By hard work I have managed to learn enough to use computers fairly well, and to work with people who know a great deal more than I. Since I have learned all this at such personal cost, I would like to share my know-ledge with others. More and more people want to know about computers, and want to know quickly.
The best way to learn is to take a course. However, many people do not have the time for this. They will have to find some other ways to get some basic information. I hope to be able to help them by writing about some of the things I have learned by myself.
I have a home computer on which I've learned in my own time. I have used it like a home study course. I have sat down with it day after day, night after night. I have forced it to give up some of its secrets. Now I can use it to do some of the work that I get paid for. And I can do this work in my own home, instead of in an office. Many people may soon be working in a computer at home, just as many now take in other people's typing.
Some things about computers are easier than you may fear. First, computers are logical. Things that at first seem difficult will make sense to you after you learn the rules. Second, it is really not hard to learn enough to use today's machines. You do not need to be a great brain. But you do have to learn to think in new ways. And you do have to keep a good bit of information in your head. Finally, there are many people around who are really enthusiastic (热心的) about computers. These people are always happy to be of help.
The purpose of the passage is to convince readers that, by studying computers at home, people can become ______.
A.computer experts
B.writers about computers
C.computer scientists
D.skilled users of computers

第3题
This need to develop a method for exchanging value was what led to the use of money. Money was a means of exchanging value without having to actually exchange the specific things you wanted. Before the use of money, people had to trade things with each other, and it was usually very difficult to decide what everything was worth in relation to each other. If you had three animals skins and your friend had two pots of dried betas, how did you know how many skins were equivalent to a pet of beans if they didn't have a price? With the introduction of money, all things could begin to hate a common value that everybody could know about. This led to a standardized set of values among people. As the power of money increased, values that were different from the majority were no longer recognized. The value of something in terms of money became the ultimate value. In order for money to function, the whole society has to agree on the same values.

A.Life was easy and food was easy to find.
B.People care more about how to survive.
C.The people took care of each other out of love.
D.There are many developed individual monetary systems.
