Cooking food over a smoky fire is found everywhere in the world. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers ， or ovens ， have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.

There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food.

The second kind of solar oven is a panel (嵌板式) cooker. It includes several flat walls, or panels, which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars.

The third kind of solar oven is a parabolic (拋物線的)cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.

You can make solar ovens from boxes or heavy-paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

To learn more about solar cooking, you can write to Solar Cookers International. The postal address is nineteen-nineteen Twenty- First Street ， Sacramento ， California, nine-five-eight-one-one, USA. Or you can visit the group's Internet website. The address is www. solarcooking. org.

One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that."  and it is even harder to say, "I was wrong? and you were right about that.

I had an experience recently with someone admit?ting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons (箱子).Then he related an incident and I began to remember clearly the incident he was describing.

I was about eight years old at the time, and I had gone into the store with my mother to do the weekly-grocery shopping. On that particular day, I must have found my way to the dairy food department where the incident took place.

There must have been a special sale on eggs that day because there was an impressive display of eggs in dozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks. Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I went to work.

The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees inspecting (examining) some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the criminal. He severely scolded me and wanted me to pay for all the broken eggs. I protes?ted my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the inci?dent, obviously the manager did not.

1.    The author was       when he wrote this article.

A. about 8      B. about 18

C. about 23     D. about 15

2.    Who was to blame for knocking off the stacks of car?tons?

A. The author. B. The manager.

C. The woman.      D. The author's mother.

3.    When the manager scolded him the author   .

A.    was frightened and cried

B.    tried to explain

C.    did not say anything

D.    felt the manager was right

4.    It can be inferred that the author .

A.    regrets arguing with the manager for what he didn't do

B.    would like to tell people never to be fooled by an egg sale

C.    has forgiven the manager for what he did to him fifteen years ago

D.    expects the woman to say sorry to him for the mistake she made
