For decades, people have been telling each other，“You are what you eat.”However, it doesn’t mean, for example, that if you eat a plant, you become a plant. At least, not for people.
For a certain kind of sea slug (海蛞蝓), however, those words are more than just a reminder to eat well. The Elysia chlorotica is a sea slug that looks like a leaf and eats by sucking the insides out of algae(海藻)．These algae, like plants, get their food by using sunlight to help make sugar.
At a recent meeting of scientists, a biologist named Sidney K. Pierce reported a surprising observation in these algaeeating sea slugs. Pierce does his research at the University of South Florida in Tampa.
Pierce already knew that these sea animals, just like plants, have the right chemical tools to turn sunlight into food. Surprisingly, now he’s learned that sea slugs aren’t simply stealing what they need to do this from algae. They’ve also stolen the recipe for how to make chlorophyll (叶绿素)，a chemical that is vital to the process, and can make chlorophyll themselves. In other words, they have started to behave like their food.
“This could be a fusion (融合) of a plant and an animal－that’s just cool，”John Zardus told Science News. Zardus is an invertebrate zoologist at The Citadel in Charleston, S．C.. Invertebrates are animals that don’t have backbones ( like slugs), and zoology is the study of animals.
Inside their cells, plants have tiny structures called chloroplasts (叶绿体)．These chloroplasts turn carbon dioxide and water into sugar using sunlight and a chemical called chlorophyll, which is known as photosynthesis (光合作用). Like plants, algae that get eaten by sea slugs also use photosynthesis. When Pierce’s slug eats algae, it separates out chloroplasts. Instead of digesting and excreting (排泄) chloroplasts, the sea slug absorbs them inside its own cells. Pierce and his colleagues already knew that once a sea slug has chloroplasts inside its cells, it can use photosynthesis to make food, which means it may not even have to eat for the rest of its life (about a year)．
But the chloroplasts use up the chlorophyll during photosynthesis, and a fresh supply is needed. Where does it come from? One idea was that when an animal absorbed chloroplasts, they came with a lifetime supply of chlorophyll.But as it turns out, that’s not the case with these sea slugs. They have stolen more than just chloroplasts.
这是一篇科普文。美国科学家最近发现了软体动物海蛞蝓的一种奇怪的生活习性：它能吸收植物的叶绿体，存入体内，自己进行光合作用，从而获取食物。
1．When people say“You are what you eat”，it generally means that ________.
A．the nutrition in a person’s diet affects his or her health
B．you’ll finally become something if you eat something
C．all people must be responsible for their actions
D．the diet cures more than the doctor
解析 句意理解题。根据下文所举实例可知，此句的意义不是你吃了什么就会变成什么。采用反证法可推知，此句的意义是“人如其食”，即饮食决定健康。
答案 A
2．We can infer from the text that John Zardus is a scientist who ________.
A．gives suggestions on the recipe
B．observes the evolution of the plant and animal life
C．studies animals without backbones
D．does research on the bones of animals
解析 推断题。根据短文中的“Invertebrates are animals that don’t have backbones(like slugs)，and zoology is the study of animals.”可知，invertebrates是无脊椎动物，zoology是动物学。由此可以判断John Zardus是一位研究无脊椎动物的科学家。
答案 C
3．Photosynthesis may be defined as the process of ________.
A．removing oxygen and increasing carbon dioxide
B．chloroplasts using chlorophyll to make sugar
C．digesting and excreting chloroplasts
D．absorbing water and sugar from the soil
解析 细节题。根据短文中的“These chloroplasts turn carbon dioxide and water into sugar using sunlight and a chemical called chlorophyll...”可知，光合作用就是利用叶绿素和阳光，将二氧化碳和水转化为糖的过程。
答案 B
4．According to the finding of Pierce and his colleagues, sea slugs, unlike other animals，________.
A．can store a lifetime supply of chlorophyll
B．never have the function of photosynthesis
C．often get eaten by plants like algae
D．can make their own chlorophyll
解析 细节题。根据短文中第四段中的“and can make chlorophyll themselves.In other words，they have started to behave like their food”和倒数第二段最后的“it can use photosynthesis to make food”可知，海蛞蝓与其他动物的区别是它们能自己制造叶绿素，并利用光合作用来为自己提供食物。
答案 D

2. His letter was so confusing that I could hardly make any________of it.
A. explanation
B. meaning

A. use
B. reason
C. value
D. sense
答案 C
3. You’ve just missed your ________， and you will have to wait for the next round.

6. Jim was late for two classes this morning. He said that he forgot both of the________.
A. rooms number
B. room number
C. room’s numbers
D. room numbers
解析 room 为无生命名词，不用 room’s 这样的所有格形式，在此可直接用名词作定语。类似地，下面一题要选B，也是一样的道理(名词作定语通常用单数不用复数)：
The boy was very happy that his mother bought him a new pair of shoes at a ________ yesterday.
A. shoes shop
B. shoe shop
C. shoes’s shop
D. shoe’s
答案 D
7．—Hello, I’d like to speak to Henry.
—Oh, which ________？ There are two________in our office.
A. Henrys；Henrys
B. Henries；Henries
C. Henry；Henrys
D. Henrys；Henries
解析 在通常情况下，专有名词具有“独一无二”性，因此它通常没有复数形式，即不可数。但是，专有名词的独一无二性有时是相对的，随着范围的扩大，这种独一无二性便会受到破坏。如在一个星期(week)内，只有一个星期六(Saturday), 一个星期日(Sunday)等，但是在一个月中甚至一年中，便有多个星期六，多个星期日了。所以我们有时可以说：We have spent many happy Sundays there. 我们在那儿度过了许多个愉快的星期日。另外一点值得注意的是，与一般的名词单数变复数不同，以“辅音字母＋y”结尾的专有名词，其直接加词尾s，而不将y改为i。
答案 C
8. Electricity, like other forms of________， has greatly increased in price in recent years.
