The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research
There are people who claim that SPS is unrealistic － because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple.
Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further.
We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades － such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy.
【小题1】Which of the following may be the best title for the passage?

Liu Qian, a magician from Taiwan, cast his spell(魔法)over an audience of thousands on the CCTV Spring Festival Show. Die-hard fans are still trying to work out the secrets behind many of the tricks he performed.

But Liu, 32, when asked, laughed off the idea that there might be an “answer” to his magic. “The most fascinating things about magic is the puzzling process. People enjoy how magicians make the impossible come true,” said Liu.

Few people today believe in the possibility of real magic. They also often fail to consider magicians’ devotion to their art. It can take a magician years’ of practice to perfect a trick before he performs it on stage.

Part of Liu’s star appeal is his astonishing skill. However, when he began in the industry, he was embarrassingly clumsy. “I could practice thousands of times for one single act. It wasn’t much fun,” he said.

No magician’s supernatural powers on stage extend to their life off stage. Liu says his life was no easier or funnier because he was a magician.

He developed an interest in magic at a young age, but didn’t consider making a living out of it until he graduated from university. He had studied Japanese language and found himself unable to find a job. “My parents never considered being a magician as a proper job. To begin with, I had little confidence I would be doing this in the long term,” he said.

Yet Liu felt a powerful calling to become a magician. “For many people, magic somehow means a miracle, which is something we all secretly wish for no matter how hard-bitten or cynical (愤世嫉俗的)we become,” he said.

Liu may be right. A popular modern dream is of the fairy godmother, who waves her magic wand (棒) and makes our dreams come true. But according to Liu, we all have the power to create magic in our lives. As Liu puts it: it’s not the magic that makes it work；it’s the way we work that makes it magic.

Europe’s deadly outbreak of a rare form of E. coli bacteria (大肠杆菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?

Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.

Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.

The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.

Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.

MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”

The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.

Moon Kim says the team hopes the system will be available before long.

MOON KIM: “We are targeting for development in commercial plants for the next several years.”

The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.

The Winner’s Guide to Success

How do successful people think? What helps them to make success? To find out the answers, an American scholar recently visited some of the most successful people in America.    1  

Be responsible for yourself

Sometimes you may want to blame others for your failure to get ahead.    2    You’re saying, “You have more control over my life than I do.”

Live life “on purpose”

Almost all successful people live life “on purpose”— they are doing what they believe they should and want to do. When you live your life on purpose, you’ll try your best to do your job or study as well as you can. You love what you do and you can find pleasure in what you do.

Write a plan

It is very difficult trying to get what you want without a good plan.     3    A good plan is like a map to you. Without this “map”, you may waste your time, money and also your energy; while with the “map” you’ll enjoy the “trip” and get what you want in the shortest possible time.

Be willing to pay the price

Nothing great is easy to get. So you must be ready to work hard — even harder than you have ever done. If you are not willing to pay the price, you won’t get anything valuable.

Never give up

   4   When you are doing something, you must tell yourself again and again: Giving up is worse than failure because failure can be the mother of success, but giving up means the death of hope.

   5   

Once an American writer was writing a novel. He could not have a good ending for his book until one night when he had a very good idea. He was so excited that he made a phone call to one of his best friends. “I’ve got a perfect idea,” he said, “I’ll put it down later and show it to you.” But he never did, because he died that night. His book was left without a perfect ending. So remember, do what you can right away. Never delay at all. 

A．It is just like trying to drive through strange roads to a city far away.

B．It seems to us that everyone knows this. But it is easier said than done.

C．Some people achieve success much later in life because they fail to realize earlier the importance of hard work.

D．In fact, when you say someone or something outside of yourself is stopping you from making success, you’re giving away your own power.

E. Someone else’s opinion of you doesn’t have to become your reality.

F. Don’t delay

G. Here are some keys to success that they give.

-- What do you think of the plan?

-- It’s easier said than _____.

A. carried out               B. carrying out             C. carry out                 D. to carry out
