一、单项选择。

1.—Whose textbook is it? Is it Jenny's?（2020年湖北鄂州）

—No, it ________ be Jenny's. Look, Helen's name is on the cover. I think it ________ be Helen's.

A. can't; must B. mustn't; must C. can't; may D. mustn't; may

【答案】A

【解析】句意：——这是谁的教科书？是珍妮的么？——不是，他不可能是珍妮的。封面上是海伦的名字，我认为一定是海伦的。

考查情态动词。can’t不可能；must必须，一定；mustn’t禁止；may可能。根据“No”可知第一空表示的是否定的推测，用can’t表示“不可能”。根据“Look, Helen's name is on the cover”封面上有海伦的名字，可知第二空是肯定的推测，用must be表示“一定是”。故选A。

2.—I don’t care what people think.（2020年湖北武汉）

—Well, you______________. Some opinions are worth weighing.

A. might B. should C. could D. would

【答案】B

【解析】句意：——我不在意别人怎么想的。——嗯，你应该在意。一些想法值得权衡。

考查情态动词。might可能；should应该；could能够；would将。根据“Some opinions are worth weighing”可知此处表示应该在意别人的看法，用情态动词should。故选B。

3.You ________ be able to control all the things that happen to you, but you can decide not to be reduced by them.（2020年江苏无锡）

A. need not B. may not C. must not D. should not

【答案】B

【解析】句意：你可能无法控制发生在你身上的所有事情，但你可以决定不被它们拖累。

考查情态动词辨析。need not不需要；may not可能不；must not禁止，不能；should not不应该。根据句中“but you can decide not to be reduced by them”可知，此处使用may not，表示推测，意为“你可能无法控制发生在你身上的所有事情，但你可以决定不被它们拖累”。故选B。

4.—Allen, shall we go to the bookstore this afternoon?  （2020年山东青岛）

— I'm sorry, David, but I ________ meet my cousin at the train station.

A. have to B. can C. may D. could

【答案】A

【解析】句意：——艾伦，我们今天下午去书店么？——大卫，不好意思，但是我不得不去火车站接我的表弟。考查情态动词。have to不得不；can能；may可能；could是can的过去式，能。根据“meet my cousin at the train station”可知此处表达的是“不得不”，用have to。故选A。

5.—Look! People outside are wearing thick coats.（202年四川成都）

—The weather________ be very cold.

A. might B. must C. can't

【答案】B

【解析】句意：——看！外面的人正穿着厚厚的大衣。——天气一定非常冷。

本题考查情态动词。might可能，表示没有把握的推测；must一定，表示没有把握的推测；can’t不可能，表示有把握的推测。根据People outside are wearing thick coats.可知，有把握推测外面的天气非常冷。故选B。

6. .Mike, you        play with fire. You        burn yourself.

A. won't; can't B. have got to; shouldn't

C. don't have to; must D. mustn't; might

【解析】句意：迈克，你不能玩火。你可能会烧伤自己。

本题考查情态动词。A.不会不能；B.必须，不应该；C.不必，必须；D.禁止；可能。第一空，根据句意可知，此空是禁止的意思，此空故填 mustn't，第二空，是表示猜测，应填might，故选D。

7.— _______ we clean the classroom at once?

   — No, you _______. You _______ clean it after school.

    A. Must; needn’t; may               B. Must; mustn’t; can

C. Shall; can’t; must              D. Need; mustn’t; may

【答案】A

【解析】情态动词的用法。根据前后句意可推断对方在询问“我必须马上打扫教室吗？”。而must引导的一般疑问句否定回答用needn’t。故选A。

8. — Good morning. I've got an appointment with Ms. King in her office.

— Morning. You _______be Mr. Jones. This way, please.

       A. will       B. must           C. can             D. might

【答案】B

【解析】情态动词的用法。will将要，表意愿；must 必须；应该，表猜测时，用于肯定句，意为“一定”，可能性较大；can能，会，表猜测时，常用于否定句和疑问句；might 可能，表猜测时，可能小。依据句意“你一定是琼斯先生吧。”，故选B。

    A. needn't             B. mustn't          C. couldn't            D. shouldn't

【答案】B

【解析】考查情态动词。句意：—我们现在可以跑着过马路吗？—不, 不可以, 我们必须等到绿灯亮。表示“禁止，不许可”时用can’t 或mustn’t ，其中后者语气更强烈一些。

11. We talked about the problem and Tim ________ doing some research first.

A. finished             B. enjoyed          C. suggested            D. practised

【答案】C

【解析】词义辨析法。finished完成； enjoyed喜欢， 欣赏； suggested建议; practised练习. 四个动词都可以跟“doing sth. ”，而suggest doing sth. 表示“建议做某事”，符合句意。故选C。

12. I go to my grandparents' home ________ with their housework every Sunday.

14. In order ________ for the competition, my sister forced herself to get up early this morning.

A. not to be late        B. not being late        C. to be late           D. being late

【答案】

【解析】语法分析法。in order to 意为“为了”，其后跟动词原形表示目的，其否定形式为：in order not to do sth. 意为“为了不做某事”。根据句意可知选A。 

15.If you have any spare milk, could you give me       ?

A. a few B. few C. a little D. little

【答案】C

【解析】句意：如果你有多余的牛奶，能给我一点吗？A. a few“些许，少许”，表示肯定，用作代词时，指代可数名词；B. few极少，几乎没有，表示否定，用作代词时，指代可数名词；C. a little “些许，少许”，表示肯定，用作代词时，指代不可数名词；D. little几乎没有，表示否定，用作代词时，指代不可数名词。此处用代词，指代milk，因为milk是不可数名词，排除A,B选项；结合句意，此处是想要一些牛奶，是想表达肯定的意思，故正确答案为C。

16.A        girl named Dong Xinyi looked after her disable father.

A. three-years-old B. three-year-old C. three years old D. three year old

【答案】B

【解析】句意：一个名叫董心怡的3岁女孩照顾她残疾的爸爸。

有连字符，连接名词时，用单数名词。three-year-old三岁的，作定语；three years old三岁，作表语。此处修饰名词girl，故缺少定语，故选B。

17.Thank you for        my grandpa when I was away.

A. taking care B. looking at C. taking care of D. look after

【答案】C

【解析】句意：谢谢你在我离开时，照顾我的祖父。

take care小心，不及物动词短语，take care of照顾，look at看。look after照顾，thank you for doing sth谢谢你做了某事，此处接宾语my grandpa故用及物动词短语taking care of。故选C。

18.________ hamburgers are junk food, many children still like them.

A. If B. Unless C. Because D. Although

【答案】D

【解析】句意：虽然汉堡包是垃圾食品，但是很多孩子们还是喜欢他们。if如果，引导条件状语从句；unless除非，如果不，引导条件状语从句；because因为，引导原因状语从句；although虽然，引导让步状语从句。根据句意可知，这两句话之间是转折的关系，故应选D。

九、阅读理解

It’s time for school! But on May 14th,170 students at Duncanville High School in Texas, the US, were told to go back home.

Why? Because they were wearing the wrong clothes to school.

Schools in the US don’t always ask students to wear uniforms. But they have dress codes(着装要求).For example, Duncanville High School tells students to wear belts, shirts without logos(标识).

Schools’ most-hated clothes are different.

In 2011,the saggy(松垮的)trousers law was passed in Florida. It stops students from wearing trousers that show body parts.

Now, “the favourite new target(目标)of the school dress code” is leggings(紧身裤),reported the Associated Press. Some schools don’t allow leggings. Other schools ask students to wear a shirt or a skirt over leggings.

Some students complain(抱怨)that schools are going too far. But schools say dress codes help protect students’ safety and make sure they grow up with good taste.

“We want to teach them that they must meet the expectations(期望)not only here in school, but also outside school,” said Andre Smith.

4. Some students complain that schools are going too far probably because     .

A. they want to grow up with good taste

【解析】试题分析：正在上学的时间，在五月十四日，邓肯维尔高中的170名学生被告诉返回家中。为什么？因为他们没有按照学校的规定来着装。邓肯维尔高中的校长说：我们想要教他们，不仅在学校，而且在校外，他们必须符合期望。

B

There are countless myths（神话）to explain how the world came to have a moon to bring light to the night time. But now there is a plan for a man-made moon. It will give us far more light than the natural Moon.

China is preparing to put a man-made moon in the sky above Chengdu by 2020. It will reflect sunlight back on to the Earth. If it succeeds, three more such objects will be sent out in 2022, according to Wu Chunfeng, a space scientist. Wu said it would be similar to how we get moonlight, but he predicted that the man-made moon would have eight times the brightness of the real one. “This is because the object will be about 500 kilometers above the Earth. That will make it a lot closer to us than the Moon, which is over 380,000 kilometers away,” Wu added.

If the plan works, the man-made moon will save a lot of power. Scientists predict that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city. And in 2022, four man-made moons can take turns to work as they will not always be in the best position（位置）relative to the Sun. Together, they can give light to an area of up to 6, 400 square kilometers on the Earth for 24hours. That means its brightness will be seen in most areas in China, reducing the need for streetlights.

6. Above which city is China preparing to put a man-made moon in the sky by 2020?

A. Beijing B. Shanghai C. Chengdu D. Wuhan

7. The underlined word “reflect” in Paragraph2 means“________”.

A. 吸收 B. 反射 C. 照耀 D. 覆盖

8. The man-made moon will be about ________above the Earth.

A. 500 kilometers B. 380,000 kilometers C. 50 kilometers D. 6,400 kilometers

9. What can we learn from the passage?

A. The man-made moon will be as bright as the natural one.

B. The man-made moon will work similarly to the natural one.

C. The man-made moon has already lit up the city of Chengdu.

D. The man-made moonlight will cover the whole china.

10. Which part of a newspaper may this passage be from?

A. Culture B. Sports C. Education D. Science

【答案】6. C    7. B    8. A    9. B    10. D

【解析】这是一篇说明文，文章主要介绍了人造月亮计划的基本情况。

6.细节理解题。根据第二段“China is preparing to put a man-made moon in the sky above Chengdu by 2020”可知是在成都。故选C。

7.词义猜测题根据“sunlight back on to the Earth”可知reflect表示“反射”。故选B。

8.细节理解题。根据第二段“the object will be about 500 kilometers above the Earth”人造月亮在地球上空500千米。故选A。

9.推理判断题。根据“Wu said it would be similar to how we get moonlight, but he predicted that the man-made moon would have eight times the brightness of the real one”可知A选项“as bright as the natural one”表述错误。B选项“The man-made moon will work similarly to the natural one.”人造月亮和月亮的工作相同，表述正确。根据“China is preparing to put a man-made moon in the sky above Chengdu by 2020”可知C选项“has already lit up the city of Chengdu”表述错误。根据“they can give light to an area of up to 6, 400 square kilometers on the Earth for 24hours. That means its brightness will be seen in most areas in China, reducing the need for streetlights”可知D选项“the whole china”表述错误。故选B。

10.推理判断题。culture文化；sports运动；education教育；science科学。文章主要介绍的是人造月亮，可推知来自于报纸的科学版面。故选D。
