As you may expect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?

         Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!

         All people in the ISS(国际空间站)have their own rooms. There’s no gravity, so they have to attach themselves to their beds, or they’ll float away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.

         This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.

         Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap, it floats in a bubble(水泡)! Astronauts used a special hose(软管)to take showers. And when they’re finished, they use a vacuum(真空的)hose to suck the dirty water off of their bodies. How do you go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.

         What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out the window. Doesn’t sound like much fun? But what if you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?

1. Which of the following can be the title of this passage?

         A. Life In Space.        B. Space Food. C. Showers In Space.        D. A Visit To Space

2.From this passage we know that _______.

         A. astronauts eat quite different food in space from what they eat on the earth

         B. astronauts ate only fruit in space in the past

         C. astronauts can only eat freeze-dried food now

         D. astronauts can only eat fruit and vegetables now

3.Astronauts attach themselves to bed so as to ________.

         A. keep themselves warm                                             B. prevent themselves from floating away

         C. have a good sleep                                                       D. feel better

4.Astronauts have to do exercise for two hours every day because ________.

         A. they have nothing to do in space                  B. they are told to do so

         C. they do so to keep healthy                              D. they do so to prevent them from sleeping

5.From the last paragraph we can guess that ________.

         A. the sun moves fast around the earth

         B. the earth circles round the sun very fast

         C. the earth is very small

         D. the spaceship circles round the earth once every 90 imnutes

Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警报器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.

Are you worried by the rising crime rate? If you are, then you probably know that your house, possessions and person are increasingly in danger of suffering from the great rise in the cases of burglary(入室行窃) and attack.
Figures indicate an ever- increasing crime rate but it is only too easy to imagine “it will never happen to me”. Unfortunately, numbers show that it really can happen to you and, if you live in a large city, you run twice the risk of being a victim(受害者).
Fortunately, there is something which you can do. Protect Alarms can help to protect your house with a burglar alarm system which is effective, simple to operate and easy to buy.
You must remember that possessing a burglar alarm is no indication that your house is filled with valuable possessions. It quite simply indicates to unwelcome visitors that yours is one house they will not break into easily so they carry on to an unprotected house where their job is made a lot easier.
Send now for our free leaflet(小册) telling you how we can Protect Alarm your house quickly, easily and cheaply. Complete and tear off the slip below and post it to us. Postage is free. Or telephone us on 327 6721 where we have a round-the-clock answering service, through which you can get the information any time you want. It costs nothing to find out about Protect Alarms.

Years ago, as a young mom with two small children, I struggled to keep up with the demands of a busy life. One day, I woke up feeling so tired that I knew something had to change!
A friend gave me some Royal Jelly—an amazing substance(物质)from the beehive(蜂房). I was doubtful, but desperate…so I tried it! In time, I began to experience renewed energy and vitality(活力)like never before! Now, over two decades later, I travel all round the country, sharing my life-changing experience. I’m grateful for the energy to keep up and love to share this wonderful discovery with others.

Ten years ago, when I was 73, my mind wanted to be busy and useful, but my body didn’t. I became tired and lethargic(无精打采的). That’s when my daughter Madeline tried to persuade me to try her special Royal Jelly. It made such a dramatic(巨大的)difference in her life, so she was sure it could help me too! Hesitating for 2 days, I gave in. She was right! I no longer felt worn out. I had a new, youthful zest(热情)for life and I’ve been OK — thanks to Royal Jelly!
Lori on Dec. 25, 2010 10:27 PM
When my mom Madeline was introduced to Royal Jelly, it affected my life, too! Mom gave me some of her fantastic Royal Jelly. Boy, things did turn around! I had more energy and stamina(耐力)and was finally able to keep up with high school and, eventually, college activities. Today, I’m a busy mom in my mid-thirties with two active boys and a new business! I have enough energy to do it all! I’m glad I took my Mom’s advice.
