2. 构成:由“助动词will(通常用于第二、三人称)+动词原形(实义动词或连系动词)”构成。

注意:will在代词后常缩写为’ll,并与主语连写在一起,如:I’ll, he’ll, you’ll, they’ll。will not常缩写为won’t。主语是第一人称时,也可用shall。

Section A

考点① Do you think there will be robots in people’s homes? 你认为人们家里将会有机器人吗?

there will be… 意为“将有……”。这是There be句型的一般将来时态,其结构是:There will be+名词+其他,也可用:There is/ are going to be+名词+其他。

There will be fewer animals in the future. = There are going to be fewer animals in the future. 将来动物会更少。 注意:there be句型不能与have/ has(有)连用;there be后面接并列名词时,谓语动词应与最近的名词在单复数上保持一致。

There is a dictionary and some books on the desk. 课桌上有一本词典和一些书。

考点② Books will only be on computers, not on paper. 书只会在电脑上,而不会在纸上。

paper此处为不可数名词,意为“纸;纸张”。 Can you give me a piece of paper? 你能给我一张纸吗? There are two pieces of paper on the desk. 桌子上有两张纸。

7 / 17

注意:① 当表示不可数名词paper的量时,可借助于a piece of“一张”;多于一张时,piece用复数。 ② paper意为“报纸,试卷”时是可数名词,复数形式是papers。

考点② Will people use money in 100 years? 100年后人们还会使用钱吗?

“in+一段时间”意为“在多长时间以后,在多长时间以内”,常用于将来时态。当提问“in+一段时间”时,用how soon。

He will give you a call in an hour. 一小时后他将给你打电话。

---How soon will your father arrive home? 你父亲多长时间到家? ---In an hour. 一小时以后。

拓展:“after+一段时间”表示过去一段时间以后,常用于过去时态;“after+时间点”表示将来某时间点以后,常用于将来时态。

考点④ There will be more pollution. 将会有更多的污染。

pollution用作不可数名词,意为“污染;污染物”。

Water pollution has made our rivers and lakes dirty. 水污染使我们的的河流和湖泊肮脏不堪。 There will be less pollution. 将有更少的污染。

拓展:pollute动词,意为“污染”。 Don’t pollute this river. 不要污染这条河。

考点⑤ Everyone should play a part in saving the earth. 人人都应该参与到拯救地球的行动中来。

play a part in (doing) sth. 意为“参与(做)某事”,part前可用形容词active, important等修饰。 Why don’t you play a part in protecting the environment? 你为什么不参与到保护环境中来呢?

拓展:take part in意为“参加,参与”。 Did you take part in the sports meeting? 你参加运动会了吗?

Section B

考点① They help with the housework and do jobs like working in dirty or dangerous places. 它们帮助做家务,以及做像在脏的或危险的地方的工作。

dangerous形容词,意为“有危险的;不安全的”。其反义词为safe,意为“安全的”。

It’s dangerous to swim in the river. 在河里游泳是危险的。 It’s a dangerous bridge. 那是一座危险的桥。 拓展:danger名词,意为“危险”。in danger意为“处于危险之中”。out of danger意为“脱离危险”。 His life is in danger. 他有生命危险。

考点② Scientists are now trying to make robots look like humans and do the same things as we do. 现在科学家正在尽力制造一些看上去像人类,并能像我们一样做事情的机器人。

8 / 17

拓展:be like意为“像”,可指性格、品德、外貌上相像,比look like的范围要大一些。

Tom is like his father. 汤姆像他的爸爸。(性格等) Tom looks like his father. 汤姆看上去像他的爸爸。(外貌)

考点③ However, some scientists believe that although we can make robots move like people… 然而,一些科学家相信,虽然我们可以使机器人像人一样动……

believe此处用作及物动词,意为“相信;认为有可能”,其后可跟名词、代词、that等引导的从句作宾语。 Do you believe what he said? 你相信他说的话吗? I don’t believe he’s only 25. 我不相信他才25岁。 注意:当主语为I/ We believe/ think/ suppose/ expect…时,若对其后的宾语从句进行否定,该否定应移至主句,即否定主句的谓语动词。

考点④ …that robots will never be able to wake up and know where they are. ……机器人永远不能醒来并知道它们在哪里。

wake up意为“醒来”。

He didn’t wake up until 11 o’clock in the morning. 他直到上午11点才醒。

注意:wake…up意为“把……叫醒”。 Please wake me up at six. 请在6点钟叫醒我。

考点⑤ But many scientists disagree with Mr. White. 但是,许多科学家不同意怀特先生。

disagree动词,意为“不同意;持有不同意见;有分歧”。disagree with sb. 意为“不同意某人”。 I’m sorry to disagree with you. 对不起,我不同意你们的意见。

注意:disagree虽然是否定的意思,但为肯定形式,在反意疑问句中,附加问句部分要用否定形式。

考点⑥ However, they agree it may take hundreds of years. 然而,他们承认这也许会花费数百年的时间。

(1)agree用作动词,意为“同意;赞成;应允”,其反义词是disagree。agree后可跟that引导的从句。 Do you agree that Jack is a violinist? 你同意杰克是一名好的小提琴手吗?

拓展:① agree with sb. 意为“同意某人(的意见)”。 We all agree with you. 我们都同意你的意见。 ② agree to do sth. 意为“同意做某事”。 Tom agrees to help with the housework. 汤姆同意帮助做家务。 (2)hundreds of意为“许多;大量;数以百计的”,表示不确切的数目。hundred, thousand(千), million(百万)等表示不确切的数目时,词尾加s,且和of连用,分别表示“数百,数千,数百万”等。 There are hundreds of students in our school. 在我们学校有数百名学生。

注意:当hundred, thousand, million等词前有数词或several,some等时,词尾不加s,也不和of连用,直接跟名词。

考点⑦ If buildings fall down with people inside, these snake robots can help look for people under the buildings. 如果倒塌的建筑物里有人,这些蛇形机器人能够帮助寻找建筑物下面的人。

(1)fall down意为“突然倒下;跌倒;倒塌”,后接宾语时应加介词from。

9 / 17

拓展:fall off从……落下,跌落 The girl fell down from/ fell off the bike. 女孩从自行车上摔了下来。 (2)look for意为“寻找;寻求”。表示有目的地找,强调“寻找”这一动作。 I’m looking for my glasses. 我在找我的眼镜。

拓展:① find意为“找到;发现”,强调“找”的结果,其宾语往往是某个丢失的人或物。

② find out意为“查明,发现”,着重表示通过理解、分析、思考、询问等“弄清楚,查明”某个情况、事实等。

考点⑧ This was not possible 20 years ago, but computers and rockets also seemed impossible 100 years ago. 20年前这是不可能的,但100年前,电脑和火箭似乎也是不可能的。

此句中possible和impossible是互为反义词的两个形容词。其中possible意为“可能的”,impossible意为“不可能的”。

It is possible to get there by bus. 可以乘公共汽车到那里。

Please don’t ask me to do such impossible things. 请不要让我做如此不可能的事情。 拓展:as… as possible意为“尽可能……”,其中两个as中间用形容词或副词的原级。 We will get your order to you as soon as possible. 我们将会把您的订货尽早送达。

考点⑨ During the week, I’ll wear smart clothes. 从星期一到星期五,我将穿讲究的衣服。

(1)during介词,意为“在……期间”。

Where will you go during the summer? 夏天你们将去哪儿?

注意:during既指某个动作在某时连续不断地进行,也指某个动作在这段时期里的某个时间发生。 (2)wear及物动词,意为“穿;戴”,其过去式为wore。

Jane is wearing a green skirt. 简穿着一条绿色的裙子。 Mr. Zhang wore glasses. 张老师戴着眼镜。 辨析:wear与put on wear “穿戴(衣物),及物动词,表状态” put on “穿(衣);戴(帽)”,及物动词短语,表动作 Put on your coat if you are going out. 如果你要出去,穿上你的大衣。
