Ears are all different, and each different thing has a meaning. Next time you look at a person, see if his or her ears are large, medium-size, or small. Look at the lobes（耳垂）.

What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck. If you arrange（排列） the 26 English letters in order and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…26 for z, you can change an English word into a number. So hard-work becomes 8+1 +18 +4+23+15+18+11="98,meaning:98" is its mark .Knowledge :11+14 +14+23 +12+5+4+7 +5="96" ,love:12+15+22+5="54," and luck: 12+21+3+11="47," a small mark. None of these words can give one a full mark. What about money? It can’t , either. Then what else? Don’t be worried.

Water is the most common substance(物质) found on the earth, but less than 1% of the earth’s water is suitable for drinking.

How green are you? Do you know how to be green?
We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.
Reduce
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don’t use a paper cup of a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
So please remember these three words: reduce, reuse and recycle.What is the passage about?
| A．How to produce things. | B．How to burn things. |
| C．How to help others. | D．How to be green. |
Which of the following is right?
| A．Don’t waste things. | B．Always throw away old things. |
| C．Always buy new things. | D．Buy too many things from abroad. |
Why is it better to use a china cup and a lunch box?
| A．You can burn them. |
| B．You can use them again. |
| C．You can throw them away. |
| D．You can change them into something else. |
To protect the environment, we should remember these three words: _______.
| A．waste, reuse and recycle | B．repair, burn and recycle |
| C．reduce, reuse and recycle | D．reduce, waste and recycle. |
The passage may come from ______.

The human brain weighs about 1.4 kilograms, but it can, hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.
◆Try to use new information immediately. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say"____"
◆Break a big number into smaller parts. For example, it's hard to memorize 109244153. But if you break it into three parts--109/244/153—it becomes easier.
◆Write out what you need to remember over and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.
◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that day.
◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what’s right and what's wrong, and it will lead to the right answer.

My name is James.
In my family there’s my mother—Anna, and my father—John, and my brother—Jeff. Jeff is the joker(滑稽的人) in the family, and we like him.
My mom’s parents will visit us this Sunday. They’re very cool. Tony, that’s my grandfather, He likes music very much, and Grace, my grandmother, can dance (跳舞).
Look at the photo. These are my mom’s brother and his wife, Uncle Peter and Aunt Emma, and their son, Bill. Bill likes to play computer games, and we have a good day this Sunday.
LONDON—Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is to send a few comets (彗星) in the direction of Earth, and its orbit (轨道)will be changed. Our world will then be sent moving into a safer older part of the solar system.
This idea for improving our climate comes from a group of US NASA (美国航空航天局) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—hopefully doubling its working life.
The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid (小行星) so that it passes close by our planet and sends some of its gravitational energy (重力势能) to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the sun,” Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter(木星) or Saturn (土星). The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to worldwide warming, although the team was actually worried about a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈)—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying sides, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算)in orbit could fire it straight at Earth—with deadly results.
There is also the question of the moon. As the present issue of Scientific American magazine points out, if Earth was pushed out of its present location, it is “most likely the moon would be stripped (剥离)away from Earth,” it states. This would greatly change our planet’s climate.
| A．A few comets are moving to the direction of Earth. |
| B．Earth’s working life is coming to an end soon. |
| C．Earth will become too hot for mankind to keep alive. |
| D．The moon is moving farther and farther away from Earth. |
| A．12 billion | B．6 billion |
| C．18 billion | D．24 billion |
| A．The comet might hit Earth and man might lose the moon. |
| B．Earth might be moved too far away and man might die because of the coldness. |
| C．The comet might hit Jupiter or Saturn and never return to Earth. |
| D．Earth’s working life might be greatly shortened. |
| A．provide | B．benefit (收益) |
| C．share | D．Endanger |
