Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.
By putting thoughts into words, you are telling yourself the logic(逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”
Try this experiment. Explain how you’ll increase your brain power, even if you have no idea how right now. Just start with anything, and create an explanation. For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help. You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain twenty minutes from now.
Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.
Want to understand a topic? Write a book about it. That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.
Writers don’t always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

Have you listened to music on an iPod? Used a computer at home? Those are just two of the ways your life was touched by the work of Steve Jobs.

Jobs, one founder of Apple Computers, died on Wednesday, October 5, 2011 at the age of 56. He had been fighting with cancer since 2004.

Steven Jobs was born in Los Altos, California. He and his childhood friend, Steve Wozniak, designed and built the first Apple computer in his parents’ garage in the 1970s. The Apple II, built when Jobs was just 21 years old, was the first personal computer to be widely sold to the public.

Steven Jobs didn’t stop there. He went on to invent more devices (设备) that allowed people to bring their own creativity to computing: the Macintosh, the iPod, the iPhone, the iPad. People found his products beautiful and easy to use.

Jobs also changed the music and film industries. He started Pixar, a film production company in 1986. Toy Story was the world’s first computer-animated feature film (电脑动画电影).

“Steve was among the greatest of American innovators — brave enough to think differently, confident enough to believe he could change the world, and clever enough to do it,” said President Barack Obama. “By making computers personal and putting the Internet in our pockets, he made the information revolution not only easy to reach, but fun ... And there may be no greater praise to Steve’s success than the fact that much of the world learned of his death on a device he invented.”

All around the world, people are talking about the effects that Jobs’ creations have had. By creating products that surprised people, he changed the way people worked and lived their everyday lives.

1.Which of the following about Steve Jobs is NOT true?

A．He was born in California in 1955.

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it's far from enough. Ladies and gentlemen, we've got to come up with some better ideas to help them.

I was very surprised, then, when I read about a plan to make cheap laptop computers for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia.[来源:学*科*网]

The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it is covered in rubber so that it is very strong and won't be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle so that children can wind the computer up to give it extra power when needed.

These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children's education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children's education they should help people to find their own solutions to their problems in the long term.

Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals at the same time. We will reduce the waste we produce and help others. In other words, we will be able to 'kill two birds with one stone', and that is always a good thing.

1. The author gives the example of Mr. Negroponte's cheap computers _______.

A. to show what high tech can bring us.

B. to illustrate the kindness of people in the developed countries

C. to show how to find business opportunities in developing countries

D. to give an example of how to help developing countries

2.Which of the following statements is TRUE about Mr. Negroponte's cheap computers?

A. His computers don’t need any power to function well.

B. His computers are covered with rubber so that they are very cheap.

C. His computers will help children in developing countries to have better education.

D. His computers will help people in developing countries to find all the solutions.

3.Where does this passage probably come from?

A. A magazine B. A newspaper C. A lecture D. An advertisement

That little “a” with a circle curling around it that is found in E – mail addresses is most commonly referred to as the “at” symbol.

Surprisingly though, there is no official, universal name for this sign. There are dozens of strange terms to describe the "@" symbol.

Before it became the standard symbol for electronic mail, the "@" symbol was used to represent the cost of something or how heavy something is. For instance, if you purchased 6 apples, you might write it as 6 apples "@" $1.10 each.

With the introduction of e-mail came the popularity of the "@" symbol. The "@" symbol or the "at sign" separates a person's online user name from his mail server(服务器) address. For instance, joe@uselessknowledge.com. Its widespread use on the Internet made it necessary to put this symbol on keyboards in other countries that have never seen or used the symbol before. As a result, there is really no official name for this symbol.

The actual origin of the symbol remains a mystery. History tells us that the @ symbol came from the tired hands of the Middle Ages. During the Middle Ages before the invention of printing machines, every letter of a word had to be copied with great efforts by hand for each copy of a published book. The monks that performed these long, boring copying duties looked for ways to reduce the number of individual strokes (笔画) per word for common words. Although the word “at” is quite short to begin with, it was a common enough word in text and documents so that those monks thought it would be quicker and easier to shorten the word “at” even more. As a result, the monks changed the shape of “t” into a circle to surround “a”, thus leaving out two strokes in the spelling “t”.

45．Which of the following is the best title of the passage?

A．How “at” developed into @. B．How @ came into being.

C．How monks invented @. D．How people wrote the cost of something.

46．Who knows the origin of @?

A．Nobody B．Monks C．Apple buyers D．Internet users

47．Which is NOT the reason for the monks to spell “at” as @?

A．Though “at” is short, it was used very often.

B．The monks wanted to be quicker and easier with their copying.

C．The monks wanted to invent a new word.

D．Copying work was long and boring for them.

48．According to the paragraph , which is TRUE about the symbol of @ today?

A．When you are online, you must use the @ symbol.

B．Kittly 163.com@is an email address.

C．In countries where @ is used, governments have given it an official name.

D．It is likely to find the @ symbol on computer keyboards worldwide.
