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.

   A. grow rice   B. plant grass

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.

(   ) 11. Doctors take a patient's temperature to see         .

   A. whether a person is ill or not

   B. if the patient's skin is loose or soft

   C. what the weather is like

   D. whether a person feels hot or cold

(   ) 12. How does the body keep the same temperature all the time?

   A. It balances the heat it gets and loses.

   B. It gives off the heat produced in it.

   C. It is always producing heat from food.

   D. It stops producing heat when necessary.

(   ) 13. When one feels too hot,he begins to sweat in order to         .

   A. produce more water

   B. give off heat quickly

   C. make the skin soft and loose

   D. get the blood to move faster

(   ) 14. We feel differently in different kinds of weather because .

   A. our body temperature is always changing with the weather

   B. warm weather makes us feel lazy and cold one makes us active

   C. we are moody according to the changes of temperature

   D. our bodies react differently to keep the same temperature

(   ) 15. We can read this article         .

   A. in a history look

   B. on a medicine bottle

   C. in a science book

   D. in an advertisement

B Mother's Day is coming. A gentleman stopped his car out of a flower shop. He wanted to order a bunch of flowers and asked them to deliver them to his mother,who was far in his hometown.

"I want to buy a rose for my mother,but I don't have enough money," said the girl.

Hearing that,the gentleman felt sorry for the girl. "It was so. . . " Then he grasped the girl's hand and entered the flower shop. He first ordered the bouquet (;花束) for his mother and then bought a rose for the girl.

Walking out of the shop,the gentleman planned to drive the girl home.

"Would you really like to drive me home?"

"Of course！”
