Question

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 Web site. The address is www.solarcooking.org.

【解析】

試題分析: 如今，隨著科技的發(fā)展，人們對太陽能有了更多的利用。在全世界的許多國家人們都在使用太陽能炊具來煮食物和加熱飲用水，以殺死細(xì)菌和其他有害生物的。在本文中作者主要介紹了三種太陽能烤爐和他們的優(yōu)缺點(diǎn)。

1.細(xì)節(jié)理解題。根據(jù)文章首段中A Swiss scientist made the first solar oven in 1767.可知答案選D

2.推理判斷題。本文介紹了人類對太陽能的利用，屬于社會(huì)發(fā)展方面內(nèi)容，由此判斷A項(xiàng)正確。

3.細(xì)節(jié)理解題。從文章第四段對Parabolic cookers的介紹“Parabolic cookers can also cause burns and eye injuries if they are not used correctly.”可知Parabolic cookers使用不當(dāng)，會(huì)造成使用者的眼部損害，故B選項(xiàng)內(nèi)容正確。

4.主旨大意題。本文主要介紹了人類利用太陽能來煮飯，烹飪。在文中介紹了三種太陽能烤爐和他們的優(yōu)缺點(diǎn)。由此判斷D選項(xiàng)內(nèi)容可以概括文章中心，選D。

考點(diǎn)：考查社會(huì)生活類短文閱讀
