一、知识复习1
1. On the other hand, some scientists point out that if you clone an embryo, you can produce valuable human tissues—such as bone or lung tissue—that could be used to save human lives. On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to producing a real-life Frankenstein’s monster.
(1) on (the) one hand…on the other hand…一方面……另一方面……
On one hand, rapid development of the economy will improve the living conditions of people. On the other hand, it will speed up environmental destruction.

(2) point at，point to和point out的意思都与“指”有关，但还是有一定区别。
point at习惯上表示指向离说话人较近的事物，意为“指着”，at是介词，着重于指的对象。point to多用来表示指向离说话人较远的事物，意为“指向”，to也是介词，着重于指的方向。point at可分开使用，point后直接跟名词或代词作宾语，at表示方向，而point to却没有这种用法，但它还表示“显示、说明”的意思。
point out表示的是给某人指示方向，要点或错误等，意为“指出”，out是副词。
根据句意，用point at，point to或point out的适当形式填空。

四、阅读理解
请认真阅读下列短文, 从短文后各题所给的A、B、C、D四个选项中, 选出最佳选项。
A
I arrived at my mother’s home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt(被子)after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church. When we began to fold and put them back into the boxes, I noticed something at the bottom of one box. I pulled it out. “What is this?” I asked.
“Oh?” Mom said, “That’s Mama’s quilt.”
I spread the quilt. It looked as if a group of school children had pieced it together; irregular designs, childish pictures, a crooked line on the right.
“Grandmother made this?” I said, surprised. My grandmother was a master at making quilts. This certainly didn’t look like any of the quilts she had made.
“Yes, right before she died. I brought it home with me last year and made some changes,” she said. “I’m still working on it. See, this is what I’ve done so far.”
I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched(缝) a piece of cloth with these words: “My mother made many quilts. She didn’t get all lines straight. But I think this is beautiful. I want to see it finished, her last quilt.”
“Oh, this is so nice, Mom,” I said. It occurred to me that by completing my grandmother’s quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another.

B
While all my classmates seem to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements

Paul Davies. USA
5. The main purpose of Steve Minear’s writing is .
A. to report his classmates’ discussion
B. to invite an answer to his question

1.intention 2. comment 3. anxiety 4. adopt 5. physician
6.agriculture 7. consideration 8. confirmed 9. profits 10. permission
二、译出下列短语

（一）完型填空
6.C从该句“she stopped crying, but still looked …”可以得出答案。
7.A从“When she came to an old man in worn-out clothes, he ……that he had spent all his money when he had accidentally got on a wrong bus and now he was trying to go home.”中可以看出，“老人在向售票员解释他为什么没有钱买票。”
8.A 售票员一听，就要求老人下车。"order the old man to get off the bus” 命令老人下车。
9.A从上下文“老人没钱想坐车回家而售票员却要求他下车”, 于是老人"beg sb to do sth” 恳求……干……

（二）阅读理解
A
CACD
B
BBAC
5.B此题为写作目的的归纳。从Can anybody explain to me just why people would go to Mars, never to return?不难得出答案B.
6.B此题为归纳大意试题。从Here are the things … the desire to explore…,the excitement…, the expectation …For scientists there is another reason. 可以得出答案为B.
7.A此题为细节判断。从Paul Davies 所说的第一段中It will happen when people finally realize that two-way trips to the red planet Mars are unnecessary.可以判断出答案为A.不少同学误选C，文中相关内容cutting the trip home would therefore reduce the danger of accidents, save a lot of money说的是减去回程的旅程会减少危险节省钱，此句是作为一个论据来为A所说的那个论点服务的。
8.C此题为细节判断。从Paul Davies 所说的第二段中Mars has all the materials for a colony to produce or make everything it needs可以判断出答案为C。
