Can you imagine astronauts' everyday life in space? They also need to eat,  sleep, exercise and relax. They do the same things as us, but they do them differently.
On Earth, we put food on a plate. Gravity holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float （漂浮）away, and astronauts must eat carefully.
Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tie the bag to a wall so that they won't float away at night.
Exercise is very important in space. On Earth,  your legs carry your body,  but in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.

Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging ( including boxes, bags, etc) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.

    Reduce  To reduce means to make less rubbish. That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可在利用的容器), taking smaller potions(份) at dinner so you don’t waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.

   Reuse   To reuse is to use things again. Think about the bags you get from the store. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the store the next time to carry your things instead of getting a new bag!

Recycle (回收利用)  Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don’t throw things in the rubbish that can be recycled to make something else. Paper, plastic, cans and bottles can all be recycled, but food, electrical waste and mobile phones can’t. When you are not sure whether something can be recycled, go to your parents and teachers for advice.

   Follow the three Rs, and every one of us can do something to save the earth. It is also the best way to save ourselves.

In Western countries, bread is one of the most important foods. When they get up in the morning many people eat toast(烤面包). They spread butter and jam on their toast. People eat bread at other times of the day too. For example, at main meals, they often eat bread with soup.

　 It's also very common to eat sandwiches. A sandwich is two pieces of bread with a filling inside salad, cheese or fish. A hamburger is a kind of sandwich.

　 There are many different kinds of bread. Some are special to some countries. For example, the baguette(法国棍子面包) is a long, thin loaf that began in France.

　 There is also white bread and whole-wheat(全麦面) bread. What's the difference? White bread is refined(精制的). It has things taken out of it to make it softer and easier to eat. The trouble is, white bread also has lots of goodness taken out. Although some people dislike the taste of whole-wheat bread, it is much healthier.

　 Some kinds of bread have additives(添加剂). They are put into the bread for many reasons. Some additives are good for you, for example, vitamin C. Others are there to make the bread last longer. Still others to make it taste better-but they do not necessarily make the bread healthier to eat!
