The temperature of your body should be always just the same,no matter whether the weather is hot or cold. That is why the doctor uses his thermometer (溫度計) when you are sick. When you are well,your temperature is about 37^. If he finds it higher than that,it is a sure sign that something is wrong.

The body keeps the same temperature all the time,because it balances the heat it produces and gives off. It is always burning up food and producing heat. It will produce heat faster when it needs to,and give off heat faster when it is too hot. Let's see how this happens.

The heat of your body is given off chiefly through the skin. When you are cold,your skin is tight and shows " goose flesh". At this time you usually prefer warming up by exercise,or put on more clothes to keep heat in.

When you are hot,the skin is loose and soft. It is supplied with more blood,and the heat is given off rapidly. If you are very hot,you begin to sweat. In this way,more body heat is given off from your skin. You wear less clothes,too,so that the heat can be given off freely. You may not want to exercise at this moment because your body is hot already,and the extra heat produced by exercise makes you uncomfortable.

You will feel differently in different kinds of weather as well. In summer,when it is hot,you feel tired and lazy. You do not want to work or play,but enjoy lying down and doing nothing. But when you get out of doors in winter,the cold air makes you feel lively. You want to run and play.

My grandfather used to have a beautiful gold pocket watch. He wore it every day. When I was small he promised (答應(yīng)) to leave it to me, "When I'm gone," he said. "This is going to be yours."

Unluckily that will never happen now. About three months ago,my grandfather came to London to stay with us. The first Sunday morning after he arrived,my youngest son said he wanted to go to the park.

"We'll do better than that," said my grandfather. "We'll go and feed the pigeons (鶴子) in Trafalgar Square."So they set off. They got home about supper time and my grandfather looked very unhappy.

"My watch," he said, "it's gone. Someone must have stolen it while we were feeding the pigeons."

"Did you tell the police?"I asked.

"No”,he said, "I didn't think that would do any good." "You should report it," I said. "Perhaps you just lost it."

"No," he replied,shaking his head. " Someone must have taken it. But I know what I am going to do."

My grandfather put an advertisement in The Evening Paper. Later on,in the afternoon,a small,nervous man,wearing a cloth cap,came up to my grandfather. " Excuse me,sir , ”he said, "are you the man who wanted your pocket watch back?"

My grandfather nodded. "Well,you must understand,sir,that I didn't do it,but the man who did it asked me to give it back."From his dirty coat,he took out the watch. My grandfather was pleased. He paid the man 100 pounds as promised and then shook hands with the man.

On the bus he wanted to have another look at his watch. With a smile on his face,he put his hand in his coat. The smile froze. The watch was no longer there.

An American group developed the rooftop gardening in the early 1980s. The group is known as ECHO. This idea was to help people living in cities who did not have land to grow vegetables. And now it is becoming more and more popular in many other countries.

To build a rooftop garden four things are necessary. You need a roof strong enough and four pieces of wood to build a box. Grass cuttings in which to plant your garden and a thin piece of plastic on which to put the cut grass are also necessary.

Begin by testing (檢測) your roof to make sure it is strong enough. Cut and collect some grass. Cover the roof with a thin piece of plastic. Then you build a box from the four pieces of wood. The box has no top or bottom. It should be about 8cm deep. It can be as long and as wide as needed. Put the box on the plastic. Then fill it with the cut grass. Water the grass and push it down by walking on it. After about three weeks the rooftop box is ready for planting.

Put the seeds directly into the wet grass. It is important that the grass is kept wet until the plants begin to grow. When the plants are growing,you will need to water them every day unless it rains. And birds must be prevented from eating the seeds or new plants. They will also need some liquid fertilizer^液體化肥) .You can make your own liquid fertilizer if you can get wastes from chickens. Put the chicken wastes in a cloth bag. Then put the bag in a big container (容器) of water. After about one week,the water becomes a good liquid fertilizer.

The rooftop garden is a good place to grow peas,tomatoes and onions. If the box is deep enough,potatoes and carrots also will grow.

(   ) 6. The passage provides a way for people without land to         .

   A. grow rice   B. plant grass

   C. grow vegetables   D. plant flowers

(   ) 7. If you want to build a rooftop garden,you should do something except         .

   A. testing the roof

   B. putting the box on the plastic

   C. cutting and collecting some grass

   D. putting a bag in a big container

(   ) 8. After planting the seeds,grass must be kept         .

   A. wet   B. dry   C. warm   D. cool

(   ) 9.        is not necessary if you want to take care of the planted seeds.

   A. To fill the box with the cut grass

   B. To water them every day

   C. Some liquid fertilizer

   D. To prevent birds from eating

(   ) 10. The passage is mainly about the way to         .
