  A report by the American Association of University Women (AAUW )notes that girls are scarce(稀少) in computer classes and in high-paying technology jobs and the reason is that girls think computer classes or jobs are stupid and boring.

  The AAUW found that girls think programming classes are populated by boys playing shooting games. The girls want no part of that.

  Meanwhile, a separate study found that boys and girls spend about the same amount of time on the Internet. But while boys are playing games, girls are doing research and e-mailing friends.

  Excuse me if I am being stupid here, but I don't see what's wrong with all this. The AAUW says that the computer culture must change so it can attract women. But to me, it seems that women are using computer very sensibly for communication and learning.

  If the computer culture should change so that boys won't waste so much time playing games.

  It was suggested in the report that girls need to be encouraged to learn the basics of the technology, to examine the cards and microprocessors, to take the computer apart and see how it works.

  But if either of my kids decided to pull the workings out of our US $2000 machine, I would break their little fingers. I have had to make this point with my son several times. My daughter thinks it would be a stupid waste of time. why would you risk making this useful machine useless?

  Girls, I think, understand well how to use a tool effectively, you don't have to put it together from various parts. That is as true for a computer as it is for a telephone.

  Girls use computers to chat with friends, make covers for their school reports and to look up things. As they move the schools and into a field of study or work, their use of computers will unavoidably grow. Girls will learn how to make the machine do what they need it to do. Any other information about computer is a waste of brain space, and girls know that clearly.

  I hate reports that try to make women such as me immediately think our daughters have suffered a lack of chances that must be made up for by some forced training.

  The AAUW found no deep barriers(障碍) to women entering the technology fields. But the group has a problem with the fact that girls don't want to.

  I thought our goal was to give girls a choice.

3.Which of the following is not supported by the author in this passage?

[  ]

Improve the world around you

You may think that inventions are far away from your everyday life. But in fact, almost everyone can invent. It’s just that they do not recognize that their idea could be the start of an invention.

Once inventors see their ideas have some practical value, they don’t let them slip away.

For example, the inventor of the dishwasher, American Josephine Cochrane, loved to give dinner parties. But she found it took too long to wash her dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So, in 1886, she set out to make one for herself.

Like Cochrane’s, most inventions are created to solve a problem. So, the first and most important step is to find the problem.

You can start by looking at what is wrong with things you use now. You can ask grandparents or neighbors if they remember ever saying:I wish someone would invent something for…”Or you can look at people in different areas such as on the street, or at school. Then you might notice situations or things in need of improvement.

Remember to record your ideas and work. This will help you develop your invention and protect it when it is completed.

The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many, varied, and unusual ways.

You can often come up with a solution for a problem by looking at it from a different angle(角度)or thinking about it in a new way.

Example 1instead of thinking of shoes as protecting your feet from the ground, think of using something to protect the ground from your feet.

Example 2instead of thinking about how you can carry oranges home from a store, think of how they can come to you by delivery or growing your own.

Example 3instead of experimenting with only one solution, can you put two or three solutions together, or arrange them in different orders?

And if one solution doesn’t work, can it be put to other uses? That was how yellow post-it notes(N次贴) came abouta failedadhesive(粘合剂)experiment proved a weak adhesive had good uses too!

After all, most inventions are not brand new. They do not come out of nowhere, but come out of things or ideas that already exist(存在).

And the hardest part of inventing, even for a lot of inventors, is coming up with a problem and finding a solution. Once you have an idea, you can always get help building your invention.

This problem-solving technique can also work in your everyday lives. So, why not try it in your studies, in your relationship with others, or even in the way you look at the world?

1. The main idea of this story is________________.

A. how to improve the world around you

B. that you can invent and how you will be able to do so

C. problem-solving technique

D. how inventors invent

2. What makes inventors different from other people is probably that________________.

A. they consider every new idea as an invention

B. they are full of creative ideas

C. they enjoy solving problems

D. they look for problems and try to solve them in a new and better way

3. What made Josephine Cochrane decide to invent the dishwasher?

A. Her love of parties.

B. Her dislike of dishwashing.

C. Her desire for something that could do the dishwashing better.

D. Her love of inventing.

4. Which of the following is one of the ways to find a problem?

A. Look at the world from a different angle.

B. Find out things that people are not satisfied with.

C. Do experiments.

D. Never let a practical idea slip away.

  YOU may think that inventions are far away from your everyday life. But in fact, almost everyone can invent. It's just that they do not recognize that their ideas could be the start of an invention.

  Once inventors see their ideas have some practical value, they don't let them slip away.

  For example, the inventor of the dishwasher, American Josephine Cochrane, loved to give dinner parties. But she found it took long to wash her dishes by hand and too many of them broke.

  You can start by looking at what is wrong with things you use now. * You can ask grandparents or neighbors if they remember ever saying:“I wish someone would invent something for...”* Or you can look at people in different areas--such as on the street, or at school. Then you might notice situations or things in need of improvement. * Remember to record you ideas and work. * This will help you develop your invention and protect (保护) it when it is completed.

  The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many, varied (各种各样的), and unusual ways.

  You can often come up with a solution for a problem by looking at it from a different angle (角度) or thinking about it in a new way.

  And if one solution doesn't work, can it be put to other uses? That was how yellow post-it notes (N次贴) came about ----a“failed”adhesive (粘合剂) experiment proved a weak adhesive had good uses too!

  After all, most inventions are not brand new (全新的). * They do not come out of nowhere, but come out of things or ideas that already exit (存在).

  And the hardest part of inventing, even for a lot of inventors, is coming up with a problem and finding a solution. Once you have an idea, you can always get help building your invention.
