Without the atmosphere there would be no weather, no wind, rain, snow, or clouds. Air is all around us; we live at the bottom of a great ocean of air. It is invisible, but we can feel it when it moves. There are miles of air above us, pressing down with great weight on the earth and everything on it. Because air presses down on us from all directions at the same time, and because we are able to bear (忍受) this weight, we do not seem to feel it. But scientists have proved that air has this weight, and that anything that has weight creates(产生) a force called pressure. As changes in air pressure take place, they, make air move.
Air is a gas that expands(膨胀) when heated, gets lighter, and moves upward. When air is cooled, it gets heavier, sinks close to the earth's surface, and flows like water in a great river. As warn air rises, cold air rushes in to take its place. 'Thus winds originate (起源). The winds that blow high above us are caused by the warmer air running away from colder air. The wind we feel near the earth's surface is the heavy colder air trying hard to catch the warmer air. Changes in temperature cause the air to move. And of course there are many changes, so air movements are taking place practically all the time.The first paragraph mainly tells us the causes of
| A．why we don't feel air | B．why atmosphere is important to us |
| C．why there is air surrounding us | D．why there is air pressure |
Air moves under such conditions that
| A．there is air pressure | B．the air is heavy |
| C．air pressure doesn't remain the same all the time | D．air comes up and down |
Which of the following pictures best tells the movements of warm air and cold air?

Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.
Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from tour parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.
If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life. So don’t wear your earphones too long. Use them less than one hour a day. Want sharp hearing? Don’t forget to do the following: Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.
Keep these things in mind! Then you won't be saying "WHAT???" when you are older.Using earphones "may not be as good a way as you expect" because _______.

What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.
A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.According to this passage, _________.

I was in a strange city I didn’t know at all, and what’s more, I could not speak a word of the language. On my second day I got on the first bus that passed, rode on it for several stops, then got off and walked on. The first two hours passed pleasantly enough, then I decided to turn back to my hotel for lunch. After walking about for some time, I decided I had better ask the way.

My mother loves flowers. As soon as warm weather comes around, you will find her planting, watering and weeding over everything .For many years we lived next door to each other, and she spent as much time in my garden as she did her own. After the flowers became plentiful each summer, she would cut colorful bouquets(花束)to enjoy inside the house—both hers and mine . I would often come home from work and find a beautiful arrangement(布置)of fresh flowers on my coffee table.
Shortly before Christmas one year, a local flower shop offered a bouquet-a-month special. It seemed to be a great way to thank her for all of the flowers she had given me through the years.
After the holidays, in early January, I drove her to the flower shop to pick up her first month’s bouquet. the small fresh colorful bouquet would hardly fill a small vase(花瓶).
I was so embarrassed(尴尬的).However, after we returned home, she began to arrange the flowers she had received.“Mom, I’m sorry, ”I told her.“I can’t believe how skimpy that bouquet is.”She looked at me and smiled.“It’s okay,”she said“It allows me to better enjoy the beauty of each one.”
