三、阅读理解

A

You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead!

Of c ourse he isn’t really dead. With any luck he isn’t even hurt. Why? Because the men who fall out of high windows or jump from fast-moving trains, who crash cars or even catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks.

There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress. Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar!

But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntman’s success depends on careful timing. For example, when he is “blown up” in a battle scene, he has to jump out of the way of the explosion just a the right moment.

Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff a thousand feet high. His parachute(降落伞) failed to open, and he was killed.

In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous actions. For nowadays there are stuntwomen, too! 36.Stuntmen earn their living by__ .

A. playing their dirty tricks

B. selling their special skills

C. jumping out of high windows

D. jumping from fast-moving trains

37.When a stuntman falls from a high building,

A. he needs little protection

B. he will be covered with a mattress

C. his life is endangered

D. his safety is generally all right

38.Which of the following is the main factor of a successful performance?

A. Strength.

B. Exactness.

C. Speed.

D. Carefulness.

39.What can be inferred from the author’s example of the Norwegian stuntman?

A. Sometimes an accident can occur to a stuntman.

B. The percentage of serious accidents is high.

C. Parachutes must be of good quality.

D. The cliff is too high.

B

The iPhone the iPad: each of Apple’s products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i”—and many other brands are following suit. The BBC’s iPlayer—which allows Web users to watch TV programs on the Internet—used the title in 2008.

A lovely bear—popular in the US and UK一that plays music and vide is called “iTeddy”. A slimmed-down version(简装本) of London’s Independent newspaper was stated last week under the name “i”.

In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use.

Most “i” products are targeted at young people and considering the major readers of Independent’s “i”, it’s no surprise that they’ve selected this fashionable name.

But it’s hard to see what’s so special about the letter “i” Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head o f the Language Center at King’s College, London, “i”works because its meaning has becomc ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or intcractive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn’t have one clear definition,” he says.

“However, thanks to Apple, the term is now connected with portability.” adds Thorne.

Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

Along with“Google” and “blog”, readers of BBC Magazines voted“i”as one of the top 20 words that have come to define the last decade.

But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. How ever, as we entered the new century, the fashion disappeared.

40.People use iPlayer to .

A. listen to music

B. make a call

C. watch TV programs online

D. read newspapers

41.We can infer that the Independent’s “i” is designed for .

A. young readers

B. old readers

C. fashionable women

D. engineers

42.The underlined word “ambiguous” means “.”

A. popular

B. uncertain

C. clear

D. unique

43.The writer suggests that .

A. “i” products are often of high quality

B. iTeddy is a live bear

C. the letter “b” replaces letter “i” to name the products

D. the popularity of “i” products may not last long

My grandfather came from Hungary and was the only one in his family who settled down in the United States. The rest of his family remained in Europe. When World War I broke out, he seemed to have become another man, downhearted. Such obvious change was not born out of concern for his welfare, but out of fear: if his only son, my uncle, had to go to war, it would be cousin fighting against cousin.

One day in 1918, my Uncle Milton received his draft notice. My grandparents were very upset. But my mother, at the age of 10, felt on top of the world about her soldier brother going off of war. Realizing how he was regarded by his little sister and all of her friends, my uncle bought them all service pins, which meant that they had a loved one in the service. All the little girls were delighted.

The moment came when my uncle and the other soldiers, without any training but all in uniforms, boarded the train. “The band played and the crowd cheered. Although no one noticed, I’m sure my grandmother had a tear in her eye for the only son. The train slowly pulled out, but not about a thousand yards when it suddenly paused. Everyone stared in wonder as the train slowly returned to the station. There was a dead silence before the doors opened and the men started to step out. Someone shouted, “The war is over!”For a moment, nobody moved, but then the people heard someone bark orders at the soldiers. The men lined up in two lines, walked down the steps, and with the band playing, marched down the street, as returning heroes, to be welcomed home. My mother said it was a great day, but she was just a little disappointed that it didn’t last a tiny bit longer.

2017-2018学年天津市耀华中学高一上学期期末考试

英语答案

1.B

【解析】考察冠词。第一空表示特指那个圣诞聚会;第二空后的success是可数名词,指一件成功的事或者成功的人。句意:—那个圣诞晚会怎么样?—应该说那个圣诞晚会很成功。

2.C

【解析】考查名词。A. match匹配;B. fit使适应;C. interest 使感兴趣; D. afford给予。句意:多数顾客对这个旅行社不满意,因为他们提供的旅行路线不能使他们感兴趣。故选C。

3.C

【解析】考查动词时态。句意:到明年大学毕业他将已经学了8年英语。主将从现的用法比较常见,常用于时间状语从句和条件状语从句中。这种情况下,如果主句是一般将来时,从句用一般现在时替代一般将来时。此处是by the time引导的时间状语从句。故选C。

4.D

【解析】考查介词。句意:随着它的经济发展,在过去的几年中,天津已经改变的无法认出。beyond recognition识别不出,故选D。

5.B

上车等(动词)。句意:警察正在设法查明火车上有多少人死了。故选B。

6.C

【解析】试题分析:考查过去分词作原因状语,分析句子可知,其逻辑主语与句子的主语一致都是he,逻辑主语省去了。句意:由于陷入沉思中,他差点撞上了前面那辆车。

考点:考查过去分词作原因状语。

7.D

【解析】考查动名词。句意:最后中年男子承认偷了女士的包。admit doing sth.承认做某事。非谓语动词的动作先于谓语动词的动作,主动关系,故选D。

8.A

【解析】考查固定结构。A. as long as 同---一样长;B. as far as远到;C. as much as多达;D. as many as和---一样多。句意:下课后她总是坐在桌子旁,有时候达到两个多小时考虑班里学生的情况。根据句意可知选A。

9.C

【解析】考查强调句型。句意:美国之行对他来说很重要,因为是那次旅行改变了他对英语学习的态度。此句是强调句型,故选C。

【名师点睛】

强调句的使用

1.用It is/was...that/who...句型表示强调。注:被强调的部分(通常是句子的主语、状语、宾语或宾语补足语)放在is/was的后面,如被强调的是人,则后面可用who,whom等代替。

2.not...until...句型的强调句:

句型为:It is/was not until+被强调部分+that+其它部分:

e.g. 普通句:He didn't go to bed until/till his wife came back.

强调句:It was not until his wife came back that he went to bed.

注意:此句型只用until,不用till。但如果不是强调句型,till, until可通用;

因为句型中It is/was not...已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了。

3.谓语动词的强调:

It is/was...that...结构不能强调谓语,如果需要强调谓语时,用助动词do/does或did。e.g. Do sit down.务必请坐。

注意:此种强调只用do/does和did,没有别的形式;过去时用did,后面的谓语动词用原形。

10.B

【解析】考查句意理解。句意:因为你说的话,这个小女孩生气地离开办公室,一句话没有说。Because of是复合介词,后跟名词、代词或what引导的从句,表示原因;此处what you had said 不是完整的句子,不能用A/C引导原因状语从句;D项是短语,后面不跟从句。由此可知B项正确。

11.C

【解析】试题分析:句意:由于有许多困难的问题要处理,新当选的总统正过着快乐的生活。这里是with的复合结构,problem与settle之间虽是被动关系,但是settle的执行者是president,在这种情况下settle用主动,这里用不定式表示将来未做的动作。故选A。

考点:考查with的复合结构的用法。

点评:本题难度适中。with的复合结构是高中阶段的重难点之一,考生容易误选A,不理解什么时候会用这种结构。如果把这种结构用在写作中这也是提高分数的亮点句。

即学即练:With prices _____ so fast, we can’t afford luxuries.

A. gone up

B. going up

C.to go up

D.being gone up

解析:B。句意: 由于物价上涨很快,我们买不起高档商品。
