知识精讲

1.【课文原句】A wonderful movie will be shown tonight. 今晚将放映一部精彩的电影。

（1）will be shown为一般将来时的被动语态，其结构为：will be+动词的过去分词。

How many people will be invited to the party next Sunday?

下周日将有多少人受邀参加聚会呢？

【拓展】一般将来时的被动语态也可以用作“be going to be+及物动词的过去分词”，表示“计划、打算、安排的事将被执行”。

e.g. The operation is going to be had in the afternoon. 手术被安排在了下午。

（2）tonight此处为副词，意为“（在）今晚”；还可作名词，意为“今晚”。

2. 【课文原句】We will be able to do anything that can be done on the earth. 我们将能够做地球上能做的任何事情。

（1）句中that can be done on the earth作不定代词（先行词）anything的定语，这样句子是定语从句。整句话意为“我们将能做在地球上可以做的任何事情”。

（2）从句的谓语用的是带有情态动词的被动语态，结构为“情态动词+be+及物动词的过去分词”。

e.g. Trees can be planted in spring. 树可以在春天栽种。

（3）on the earth意为“在地球上”

【拓展】① on earth意为“在人间，在世界上”

② on earth意为“到底，究竟”，用于how，who，what，where，why等疑问词之后可以加强语气。

e.g. I don’t know who on earth would do such a thing. 我不知道到底谁会干这样的事。

3. 【课文原句】But in 2048 books will be displayed on soft screen.但在2048年，书籍将在软屏幕上显示。

（1）display（名词/动词），意为“陈列，展示”。

（2）on soft screen意为“通过柔和的屏幕”，soft柔和的，不刺目的。screen前用on。

4. 【课文原句】Many spaceships will be sent into space.许多宇宙飞船将被送入太空。

（1）① send into意为“被送进......”

e.g. The thief was sent into the prison last week. 这个贼上周被送进了监狱。

② send sth. to sb. = send sb. sth. 把某物派送给某人

5. 【课文原句】Some scientists believe that aliens will be found in outer space.一些科学家相信在外太空会发现外星人。

（1）scientist（可数名词），意为“科学家” science（名词），意为“科学”

（2）① believe sb. 意为“相信某人的话，与这个人的品质无关”

e.g. I believe you. = I believe what you said. 我相信你说的话。

② believe in sb. 意为“信任某人，相信某人的价值，也可指信仰，信奉（真理）”

e.g. Some people believe in God. 一些人信奉上帝。

③ believe that+从句

6. 【课文原句】One American scientist thinks they have already come to the earth，and they are reading

information on the Internet in order to learn about human culture. 一位美国科学家认为他们已经来到地球，他们正在互联网上阅读信息，以便了解人类文化。

（1）information（不可数名词），意为“信息，消息，情报”

（2）on the Internet意为“在互联网上；通过互联网”

（3）介词短语in order to意为“为了......”或“以便于......”，后接动词原形作目的状语，放在句首时加逗号与整句分开。

e.g. In order to improve your English，you’d better use it as much as possible.

为了提高你的英语水平，你最好尽可能多地使用英语。

【链接】in order to ...引出的目的状语可以转换为由in order that ...或者so ... that ...引出的目的状语从句，语义不变。

e.g. They work day and night in order to finish the work on time. =

They work day and night in order that/so that they can finish the work on time.

为了能够按时完成工作，他们昼夜不休。

7. 【课文原句】I don’t think aliens can be found in space. 我认为太空中找不到外星人。

（1）主语(第一人称)+think/suppose/believe/imagine/expect，后面宾语从句中的否定词not要前移到主句，即否定前移 。

e.g. I don’t think it will rain tomorrow.我认为明天不会下雨。

(2) 当主语是二、三人称时否定一般不转移。

e.g. She thinks it won’t rain tomorrow.她认为明天不会下雨。

8. 【课文原句】I won’t believe there are aliens until I see them with my own eyes. 直到我亲眼看到，我才相信有外星人。

【点拨】 not…until… 直到……才……(until引导了时间状语从句)，从句中要遵循主将从现的原则。

【对比】…until… 和not…until…

①until表示动作、状态的持续，强调“一直到……为止”，或强调某个动作或状态一直持续到另一个动作或状态出现之前。常与表示延续性动作的动词连用。

e.g. They kept waiting for her until she came back.

他们一直等她，直到她回来。

②not…until表示“到……为止；直到……才”，常与表示瞬间性动作的动词连用

e.g. They didn’t leave until she came back.

直到她回来，他们才离开。

II. 单项选择

1. I ______think the answer ______ right because there's a mistake in spelling.

A./, is B. /, isn't C. don't, is D. doesn’t. is

【答案】C

【解析】

本题考查I think句型的否定前移的用法，当主语是第一人称时，谓语动词是think, believe, suppose等词时，其否定句中的否定词迁移到主句中，从句用肯定形式。从句主语the answer为单数，所以谓语动词用is，故选C。

2, —Teachers often say that mistakes should ______ in time.

—I think so. It's really good advice.

A. correct B. be corrected C. have corrected D. be correct

【答案】B

【解析】

根据宾语从句的主语mistakes，是谓语动词correct的承受者，二者构成被动关系，所以用被动语态，句中又含有情态动词should，故用含有情态动词的被动语态，其结构为：情态动词+be+及物动词的过去分词，故选B。

3. I could ______control my feelings at the moment. The movie reminds me of my childhood.

A. really B. nearly C. hardly D. lonely

【答案】C

【解析】

really表示真正得，nearly表示几乎，lonely表示孤独的，hardly表示几乎不．根据题干中The movie

reminds me of my childhood． 可知这部电影让我想起了我的童年，所以在那个时刻我几乎不能控制我的情感。故选C。

4.—I want to be a scientist to do some research on green cars when I grow up.

—Work hard. I’m sure your dream will be ______.

A. realized B. considered C. invented D. come true

【答案】A

【解析】

考查动词短语辨析．题中给出中文意思"我相信你们的梦想未来会实现！"，在英文句子中，缺少"实现"，come true 为不及物动词不用于被动语态中，realize实现，为及物动词，可用于被动语态，故选A。

5. All these gifts must be mailed immediately ______ in time for Christmas.

A. in order to have received B. in order to receive

C. so as to be received D. so as to be receiving

【答案】C

【解析】

句意：所有的这些礼物必须马上被寄出，为了及时让这些圣诞节的礼物被收到。这里用so as to与in order

to都可以表示目的，又因为gifts与receive之间是被动关系，故选C。

6. We don't know the love of our parents ______ we become parents ourselves one day.

A. when B. after C. until D. since

【答案】C

【解析】

until直到…；after在…之后；when当…的时候；since自从…以来．根据"We don't know the love of our

parents "以及"we become parents ourselves one day．"因此可知这句话的意思是"我们直到有一天也为人父母的时候才懂的父母的爱．"用not…until句型"直到…才"．故选C。

7. I think all the heavy and difficult jobs ______ by machines and robots in the future.

A. do B. will do C. are done D. will be done

【答案】D

【解析】

think后是宾语从句，主句是一般现在时，从句时态不受限制，结合in the future用一般将来时，主语jobs是动词do的承受者，故用一般将来时的被动语态will+be+过去分词，故选D。

8. — Shall we go to visit the Science Museum this Saturday?

— ______ . I can’t wait to go.

A. I hope not B. That sounds great C. Yes, I will D. Not at all

【答案】B

【解析】

9. Will you ______ come next week?

A. can B. be able to C. able to D. can be able to

III.阅读理解

It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to

1,400 people.

It is China’s new Super Bus. It is going for a test run in Beijing at the end of this year. Some other cities are

also interested in running the Super Bus. They hope the traffic problems will be solved.

The Super Bus runs along fixed tracks (固定轨道) . The bus sits on top of two 2.2-meter-tall legs. The legs

have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space.

The bus runs on electricity and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou,

says a lot of traffic jams (堵塞) will be reduced.

The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料) every year,

according to Song.

“To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more

expensive to build.”Song said.

Some people worry that the Super Bus may not be safe. However, Song says there’s no need for concern. The

Super Bus has laser scanners (激光扫描仪) between its legs. The scanners make sure the cars keep a safe distance.

A. 1,300 B. 1,500 C. 1,700 D. 1,900
