Do you love having your own room? Do you hate to clean it?

Sometimes your room becomes so messy(杂乱), and you can’t find what you want. You can’t even see the floor!

    It isn’t because you are lazy. It is because you are not arranged(有安排的).

    But don’t worry. American writer Julie is here to help. She has written “Organizing from the Inside Out for Teens” to help make your life more organized.

    In the book, the writer points out（指出）that your room is the only space in the world just for you. If you keep it clean and tidy, you will find things easier and have success in life!

    But, to have more success, you must arrange all parts of your life. Not just your room! The book gives many tips to help you do this:

（1）       Always put things back where you find them.

（2）       Keep anything important in one easy-to-reach(伸手够到) drawer.

（3）       When you buy a new textbook, put your old ones in a drawer.

（4）       Put labels (标签) on your drawers saying what is in them.

（5）       Make a plan for each day. Then you will know what you should be doing at all times.

（6）       Keep to your plan.

If you follow these tips, you will learn to arrange your space and time. And your future will be full of success!

56. As we know, we put food on a plate and water in a glass on earth. Gravity(引力) holds the food down and keeps the water in the glass. But in space, there is almost no gravity. So food can float away, and astronauts must eat and drink carefully.

57. in space, sleeping is very different. Some astronauts like to float in the air, but some astronauts like to be in a sleeping bag. They tie the bag to a wall so that they can’t float at night.

58. 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. This is bad for their legs, or they exercise for   thirty minutes every day. They often use an exercise bike for this.

59 Many people can use computers, but few of them know how to look after them. Remember the following when you use computers: Keep your computer in a cool, dry room; do not put water or food near your computer; keep you screen clean and not too bright.

60. Some things can carry messages. For example, a sing at the bus stop helps you to know which bus to take. Sings on the door tell you where to go in or out. Have you ever noticed that there are a lot of signs around you and they you receive messages form them all the time?

Today  1  people live in cities．So there is usually little room in a city to grow food．2   of the land in a city is used  3  homes, shops, roads and parks．

Most food for city  4  is grown in the countryside．It is often brought to the city by truck, train and plane．Some food is even carried into the city by car．

The  9    used by cities comes mostly(主要的) from rain．But people cannot use the rain  that frills on cities．The rain  10  dirty as it falls  11  dirty air．Once it hits city buildings or streets, the rain will  12  more dirt(尘埃)．It is not good for drinking  13  bathing．

So cities must reach out to the  14  countryside for water．There, the rain falls through  15   onto trees and grass．The fallen rain runs into rivers and lakes．So it is important to keep both cities and the countryside clean．
