2、n dirty or dangerous places.Today there are already robots working in factories.For example，they can help to build cars，and they do simple jobs over and over again.Fewer people will do such jobs in the future because they are boring，but robots will never get bored.Some scientists believe that there

3、will be more robots in the future.However，they agree it may take hundreds of years.Scientists are now trying to make robots look like humans and do the same things as us.Some robots in Japan can even walk and dance.These kinds of robots are fun to watch.But scientist James White thinks that it will

4、be difficult for a robot to do the same things as a person.For example，its easy for children to wake up and know where they are.Mr.White thinks that robots wont be able to do this，but some scientists disagree.They think that robots will even be able to talk like humans in 25 to 50 years.New robots w

6、r know what will happen in the future！,你认为你将会拥有自己的机器人吗？当我们看关于未来的电影时，我们有时候会看到机器人。他们通常像人类的仆人。他们帮助做家务，并在肮脏的、危险的地方工作。现在已经有机器人在工厂里工作了。例如，他们可以帮助造车，并且能够反复地做一些简单的工作。在未来会有更少人做那样的工作，因为它们很无聊，但是机器人从不会感到无聊。一些科学家相信将来会有更多机器人。然而，他们都一致认为这要经历上百年的时间。科学家们现在正尽力让机器人看起来像人并和我们做一样的事情。在日本，一些机器人甚至会行走和跳舞。这些种类的机器人看起来会是很有趣的。但是科学

7、家詹姆斯怀特认为对机器人来说和人做一样的事情会是很难的。例如，对一个孩子来说醒来和知道他们在哪里是容易的。怀特先生认为机器人将不能做到这点，但是一些科学家不同意。他们认为25到50年后机器人甚至能像人一样交谈。新生机器人将有许多不同的形状。一些将看起来像人，另一些可能像蛇。如果楼房倒塌而里面有人，蛇形机器人将能够帮助寻找楼房下面的人。现在看起来似乎是不可能的，但在100年之前，电脑、火箭似乎也是不可能的。我们永远不知道未来会发生什么！教材知识详解1They help with the housework and do jobs like working in dirty or dangerou

8、s places.他们帮助做家务，并在肮脏的、危险的地方工作。dangerous adj.有危险的；不安全的指对他人或物构成了危险或威胁。The tiger is very dangerous.老虎是很危险的。danger n. 危险，in danger意为“处于危险之中”，指自身处于危险之中。Some animals are in danger.一些动物处于危险之中。【例题】Its _ to climb(爬) the tall tree.Be careful.Adanger BdangerousCbusy Ddifficult点拨：根据“小心”可知“爬那棵高树是危险的”。danger是名词，

9、意为“危险”。is后接形容词作表语。答案：B2Today there are already robots working in factories.现在已经有机器人在工厂里工作了。本句含有固定句型：There is/aresb./sth.doing sth.表示“有某人/某物在做某事”。There are some boys swimming in the swimming pool.有一些男孩在游泳池里游泳。There is a bag lying on the ground.有一个包躺在地上。【例题】There will be robots _ with us in the future

10、.Atalk Bwill talkCtalking Dtalked点拨：句意为“将来会有机器人和我们交谈”。There will besb.doing sth.是There is/aresb./sth.doing sth.的变形。答案：C3For example，they can help to build cars，and they do simple jobs over and over again.例如，他们可以帮助造车，并且能够反复地做一些简单的工作。over and over again 多次；反复地He told me to look after his dog over and

11、over again.他再三地告诉我照顾他的小狗。I dont like to do boring exercises over and over again.我不喜欢反复地做无聊的习题。once again 再一次Lets do that once again.我们再做一次。【例题】Teachers shouldnt ask students to copy the words _.Its simple and boring.Aagain Bonce againCover and over again Dagain over and over点拨：A项意为“又一次”；B项意为“再一次”；C项

12、意为“多次；反复地”；D项短语有误。由句意“教师不应该让学生反复地抄写单词。那简单又无聊。”可知C项符合句意。答案：C4Some scientists believe that there will be more robots in the future.一些科学家相信将来会有更多机器人。believe v相信；认为有可能作及物动词，之后可以接名词、代词作宾语，也可以接宾语从句。I believe that hell come here.我认为他会来这儿。若要否定believe 后所跟宾语从句的意义，则往往承前否定。这一点与think相同。I dont believe that he wil

13、l come here.我认为他不会来这儿。【例题】I _ believe he _ speak three languages.Adont；cant Bdo；cantCdont；can Dam not；can点拨：浏览各选项看出本句是否定句，believe 后接了宾语从句，否定时前置，故排除B项；否定前置，后面用肯定形式，故排除A项；主语是I，动词是believe，所以否定时要借助于助动词dont，排除D项。句意为“我认为他不会说三种语言”。答案：C5However，they agree it may take hundreds of years.然而，他们都一致认为这要经历上百年的时间。h

14、undreds of许多；大量，后接名词复数。类似用法的还有：thousands of 成千上万的；millions of 数百万计的；billions of 十亿计的Hundreds of people lost their homes in the floods.数百人在洪水中失去了家园。hundred前有基数词时，hundred不用复数形式，且后面也不用of。thousand，million，billion同hundred。There are eight hundred workers in the factory.这个工厂有八百名工人。【例题】There are _of student

15、s in our school but only _ of them are girls.Ahundreds；two hundred Bhundred；two hundredsChundreds；two hundreds Dhundred；two hundred点拨：hundreds of students意为“数百名学生”；two是基数词，因此hundred用原形。句中第二空格后of 意为“的”，并非two hundreds of，故选A项。句意为“我们学校有数百名学生，但其中只有二百名是女生”。答案：A6Mr.White thinks that robots wont be able to

16、 do this，but some scientists disagree.怀特先生认为机器人将不能做到这点，但是一些科学家不同意。be able to 能够做某事；会做某事He is able to swim.他会游泳。be able to 和can二者都可以表示“能；会”。在表示现在和过去“力所能及”时，二者可以互换。I can/am able to speak a little English now.我现在会说一些英语。He was able to/could run fast when he was eight.他八岁时就能跑得很快了。但它们也有一些区别：be able to可用于各

17、种时态；可用于不定式的后面；不能用于表示猜测的句中。can只用于一般现在时和一般过去时。不能用于不定式的后面。表示猜测时，只能用can。You will be able to learn another foreign language in two years.两年后你将能够学另一门外语。I hope to be able to go fishing with you.我希望能和你一起去钓鱼。Mr.King cant be at home now.现在金先生不可能在家。disagree v. 不同意；持不同意见；有分歧，其反义词是agree。disagree with sb.不同意某人He

18、disagrees with me and Im very angry.他不同意我，我很生气。disagreement n. 分歧；不同观点，反义词是agreement。We students often have some disagreements.我们学生经常有分歧。【例1】Take it easy.I am sure you _ work it out soon.Awill can Bwill be able toCbe able to Dcould点拨：句意为“别着急，我相信你很快就会把它给解出来的”。用be able to 的将来时。A项错误，因为can没有将来时；C项中的be受人

19、称单复数所决定；D项不符合时态。答案：B【例2】It _ be our English teacher，because he is in Shanghai now.Acan not Bcould notCisnt able to Dis able to not点拨：浏览题干，根据后半句句意“因为现在他在上海”可知“那肯定不是我们的英语教师”，故表示推测，排除C、D两项；could在表示推测时，可能性要小，故选A项。答案：A【例3】At this point，Bob and Tom have some _.But who do you _ with?Adisagree；disagreements

20、 Bdisagreements；disagreeCagreements；disagree Ddisagreement；disagree点拨：some后接disagreements或agreements都可，排除A、D两项；C项在句中与句意不符；故选B项。句意为“在这点上，鲍勃和汤姆有一些分歧。但是你不同意谁呢？”。答案：B7If buildings fall down with people inside，snake robots will be able to help look for people under the buildings.如果楼房倒塌而里面有人，蛇形机器人将能够帮助寻找楼

21、房下面的人。本句是复合句，if引导的是条件状语从句。fall v. 倒塌；跌倒；掉落，过去式为：fell。Rain is falling.雨正在下。fall down 突然倒下；跌倒；倒塌An earthquake happened and many houses fell down.地震发生了，许多房屋都倒塌了。fall n. 秋天Its cool in fall.秋天很凉爽。look for 寻找；寻求，强调找的过程。Hes looking for his dog.他正在寻找他的小狗。look for，find，find out(1)look for意为“寻找”，强调“寻找”的过程。(2)

22、find指“偶然发现”或“几乎无困难地找到”。强调“寻找”的结果。(3)find out指通过观察、探索而发现事实的真相。一般指主观有意识的动作。The police found out who was the criminal.警察查明了谁是罪犯。The police looked for the thief everywhere，but they didnt find him.警察到处找那个小偷，但没找到。【例1】Last night his house _ after a heavy rain.Afell down Bfalls downCfelt down Dfeels down点拨：

23、根据last night可知时态用一般过去时；fall 是动词原形，过去式为fell；而felt是feel的过去式。句意为“昨天晚上，他的房子在一场大雨后倒塌了”。答案：A【例2】Lily _ her shoes，but she didnt _ them.Alooked for；find Bfound；looked forClooked for；find out Dfound out；looked for点拨：look for强调“寻找”的过程。find强调“寻找”的结果。find out指通过观察、探索而发现事实的真相。综上所述，只有A项符合。句意为“莉莉寻找她的鞋子，但是没有找到它们”。答

24、案：A8That may not seem possible now，but computers and rockets seemed impossible 100 years ago.现在看起来似乎是不可能的，但在100年之前，电脑、火箭似乎也是不可能的。possible adj.可能存在或发生的；可能的Its possible for an eightmonth baby to walk对于一个八个月的婴儿来说，会走路是可能的。impossible adj. 不可能的，是possible的反义词。Nothing is impossible if you try your best.如果你尽

26、s.在将来，人们会更多地工作，所以他们可能有更少的假期probably adv.很可能；大概可放于句首，也可放在助动词、系动词、情态动词之后或实义动词之前。Probably he has come.他可能已经来了。Itll probably snow.也许要下雪。probably，maybe，perhaps，may beprobably 也许；可能，表示把握性很大的事情。maybe或许；大概，把握性比probably小，相当于perhaps。常放于句首。Maybe/Perhaps he is right.或许他是对的。may be 可能是，是情态动词maybe，常用作谓语动词。Maybe he

27、 is a doctor.He may be a doctor.他可能是一名医生。【例1】 He will _come tomorrow.Aperhaps BmaybeCprobably Dmay be点拨：浏览题干可知will come是谓语动词，故排除D项；A、B两项常放于句首，故排除；C项意为“或许；大概”，可放于句首，也可放于助动词、系动词、情态动词之后或实义动词之前，符合句法。句意为“明天他可能回来”。答案：C【例2】 Maybe my uncle is at home.(改为同义句)My uncle _ _at home.点拨：maybe意为“或许；大概”，是一个副词。句意为“或许

28、我叔叔在家”。第二句缺少谓语，又含有“大概；或许”之意，故用may be，是情态动词后接be，可作谓语。答案：may be交际用语指导：你对未来有何愿望？你是怎样规划未来的蓝图的？如何表达对于未来的设想？请看本单元涉及对未来的预测的对话：1Will people use money in 100 years?100年后人们会使用钱吗？No，they wont.Everything will be free.不，他们不会。一切都将免费。对于一般将来时的一般疑问句的简略回答，肯定形式为：Yes，主语will.否定形式为：No，主语wont.2I think there will be more p

30、00 years?No，I think kids will study at home.ADo；have BAre；/CWill；be DWill；have解析由时间状语in 100 years可知用一般将来时；句前有there说明要用there be结构，故选C项。答案C句意“100年后会有学校吗？”“不会，我认为孩子们将会在家里学习。”【例2】 I think there will be fewer trees.I dont agree _ you.Aat BtoCon Dwith解析agree with sb.意为“同意某人的意见或观点”。答案D句意“我认为将会有更少的树。”“我不同意你的观点。”【例3】 Who do you think_ here tomorrow?I think Lucy will.Aco
