大家好！我是今天的新主持surah,非常高兴能与大家见面，以后还会有其他4位新主持陆续上任，希望大家支持他们呦~~
其实回首起来，偶断断续续听SP也有一年左右了，但真正开始集中听写还是这个暑假，有雪秋等各位大人的亲切教导，还有各位学友蜗牛的互相鼓励，进步真的很快
不多说了，下面开始我们的学习，是继续昨天太阳能做饭的话题了，其实这种科学性的文章我一向都比较怵，不过我坚信只要熟悉其中原理，多练习就会好的
此主题相关图片如下：
昨日回顾
n.炊具, 蒸(煮)机,(非生吃的)为烹食所种水果
n.生物体, 有机体
此主题相关图片如下：
今日总结
由于有昨天内容的铺垫，所以今天没有错（当然自己在一些小细节方面还有些错了
）
单词
panel n.面板, 嵌板, 仪表板, vt.嵌镶板
container n.容器(箱,盆,罐,壶,桶,坛子), 集装箱
parabolic adj.比喻的, 寓言似的 （但自己文中感觉不是，希望大家来讨论~）
翻译：
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.
第二种太阳能炉灶是嵌板炉灶。这种炊具包括几个扁平的围壁，或称为面板，它们直接将太阳光反射到食物上。食物被搁置在一个单独的塑料或玻璃容器内，这种容器随时就携带着热能。人们能很快地建造面板太阳能炉灶，并且供给品用得非常少，花费也不是太多。例如，在肯尼亚，人工造一个面板灶只需要2美元。
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.
第三种太阳能炉灶是抛物面形炉灶（根据资料先这么翻译）。它具有圆形围壁以直接瞄准阳光使其射入炉灶的底部。在抛物面形炉灶里食物会熟得很快。可是，这种炉灶不易制造。它们必须经常多次瞄准以随着太阳运动。同时，如果没有正确使用，抛物面形炉灶也能会引发火灾和眼部灼伤。
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.
你可以用从盒子到硬纸的一系列材料制作太阳能炉灶。这些材料是不会着火的。纸在温度达到232摄氏度时才会着火，而太阳能炉灶是永远不会达到这么热的。它在较低温度下用很长一段时间来煮食物，这就允许人们在做饭的同时做其他事。
作业：
1.It includes several flat walls, or panels, that directly reflect the sun's light onto the food.
2.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.

再介绍一下三种太阳能灶具样式：
Box Cookers
Panel Cookers
Parabolic Cookers
最后带大家观览奇形怪状的太阳能炊具：
不知道大家对我今天做的有什么评价呢？欢迎发短消息给我建议，我会积极采纳呦~~希望有问题跟贴讨论，我们大家一起探讨
