Question

As we all know, millions of people worldwide cook their food over smoky fire every day. 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 cooker, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in seventeen sixty-seven. 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 cooker. It includes several flat walls or panels that 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 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 two hundred thirty-two 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.

【名师点睛】

阅读理解中的细节题是常考题型，是指原文提到了某事物、现象或理论，题干针对原文具体叙述本身发问。包括直接理解题（在原文中可直接找到答案，常用who, what, when, where, why和how等提问。）对直接理解题，考生可以首先从问题中找到关键词，然后以此为线索，运用略读及查阅的技巧在文中迅速寻找这一细节，找到后再把这一部分内容仔细阅读一遍，仔细比较所给选项与文中细节的细微区别，在准确理解细节的前提下，最后确定最佳答案。

以本文24题为例：根据第三段最后一句If you have much food to cook意为“如果你有很多食物要煮”，考生一定要抓住much food这个关键词，然后在第三段最后一句A box oven is effective for slow cooking of large amounts of food.中的large amounts of food与题目中的much food相对应。可知烹饪大量食物需要a box oven。
