模块质量测评(五) Module 5 A Lesson in a Lab(时间：90分钟满分：110分)第一部分阅读理解(共两节，满分30分)第一节(共10小题，每小题2分，满分20分)阅读下列短文，从每小题后所给的A、B、C、D四个选项中，选出最佳选项。

AWe're surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin.Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can't be mixed with vinegar, because it can produce poisonous gas. Without chemistry, we wouldn't have fireworks displays on important days.Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw (生的) food. Baking is a great example of chemistry. Too much or too little of any ingredient makes a difference to the result of baking, for example, the dough (面团) won't rise or the cake will be flat.Chemistry isn't something that just lives in a lab; it's something that you meet hundreds of times every day. If you know how chemistry works, you will get a greater understanding of the science behind some of the simplest­looking things.语篇解读化学课上的实验让我们清楚地看到了化学过程，但是在日常生活中你发现了随处可见的化学了吗？1．What's the main idea of Paragraph 1?A. Chemistry is easy to see around us.B. Sometimes chemistry is hard to see around us.C. How a science teacher does a big experiment.D. Few things in everyday life contain chemistry.答案与解析 B 细节理解题。
