7、re will be robots in peoples homes? 本句是一个含有宾语从句的主从复合句，Do you think是主句，there will be.是宾语从句。如果do you think放在句中，则为插入语，常放在疑问句之后，结构为：疑问词+do you think+主语+谓语+其他成分？ e.g. Do you think he is a teacher? What time do you think the train will arrive here?there will be意为“将有，会有”，是there be句型的一般将来式，其否定形式是there wont

8、be.,一般疑问句形式是Will there be.?有时可以与There is/are going to be.相互转换。 e.g. There will be a film this evening. 否定句，疑问句，答语拓展：there be句型的一个重要用法是“就近一致”原则，即谓语动词be和最靠近它的名词在数上保持一致。 e.g. There is a book and two rulers on the desk. There are two rulers and a book on the desk.there be与have/has的区别：前者表示某地存在某物；后者表示“拥有”

9、的意思。二者有时可以互换。 e.g. Our school has twenty classes. =There are twenty classes in our class.(2012.江苏扬州）-Why are you in such a hurry, John? -There _ a basketball match between Class Three and our class in ten minutes. A. is going to be B. is going to have C. will have D. will holdA2. I think every home

10、will have a robot. 这是一个含有宾语从句的主从复合句，I think为主句，every home will have a robot 是宾语从句，用来表述自己的看法。 e.g. I think the boy will buy a few new books about English.拓展：根据语法的惯例，I think/suppose/believe等后的宾语从句如果是否定句，要把否定转移到主句的动词上，这种现象称之为“否定转移”。 e.g. I dont think he can swim. I dont think you can go there by bus.思考

11、：其反意疑问句的变法every此处用作形容词，意为“每个的，每一”。 e.g. Not every horse can run fast.辨析：every与eache.g.Every teacher knows her. There are lots of trees on each side of the road. Each of us has a dictionary. every形容词指三者或三者以上范围中的“每一个”，侧重总体，不能单独使用each形容词指两者或两者以上中的“每一个”，侧重个体代词可作主语或宾语，其后可跟介词of every与each的区别every用来表整体，eac

12、h用来表个别，each最低需是两，every最低需是三。every作主用单数，each可单也可复，作主、定用单数，其他情况用复数。3Books will only be on computers，not on paper. 书只会在电脑上，而不会在纸上。 paper n. “纸，纸张”，是不可数名词。表示“一张纸”用a piece of paper，“两张纸”用two pieces of paper。e.g. There is a piece of paper on the table.桌子上有一张纸。paper n. “试卷”，作可数名词，有复数形式。 e.g. I lost a histo

13、ry paper. 我丢了一份历史试卷。【例题】 The teacher marked(批分数) the exam _ and wrote the students grades on a piece of _.Apapers；paper Bpaper；papersCpaper；paper Dpapers；papers解析: 根据前半句的marked可知第一空填papers，意为“试卷”，是可数名词；第二空填paper，构成固定搭配a piece of paper “一张纸”。答案 A句意老师批阅了试卷并把学生们的分数写在了一张纸上。4.Will people use money in 100

14、 years?in 100 years意为“在100年以后”，其中in为介词，其后跟一段时间表示“.之后”，通常用于一般将来时，对其提问时须用how soon（多久）。 -How soon will your mother finish cooking dinner? -In an hour.辨析：in 与afterin和after都表示“在.之后”，它们的用法见下表： e.g. He will be back in two days. He started on Sunday and arrived in Beijing after three days.in用来表示以现在为起点的将来某一段

15、时间之后，后接时间段用于将来时after既可接时间点又可接时间段用于过去时5There will be fewer people.将有更少的人。本句是含有there be句型的一般将来时的简单句。 结构为：There will be主语其他。其否定形式是在will 后加not；疑问句形式是把will 提到there前。简略肯定回答：Yes，there will.简略否定回答：No，there wont.e.g. There will not be enough room for people to live in. 将没有足够的给人住的空间。e.g. Will there be fewer a

16、nimals in the world? 世界上将有更少的动物吗？fewer adj. (few的比较级) 较少的；更少的，修饰可数名词的复数形式。 e.g. I have fewer friends.我有更少的朋友。fewer，less和more(1)fewer同上。 e.g. My friend has fewer apples than I. 我朋友比我的苹果少。(2)less较少的；更少的，little的比较级，修饰不可数名词。 e.g. I have less money in my bag. 我包里的钱更少了。(3)more更多的，many和much的比较级，可修饰可数名词，也可修

17、饰不可数名词。 e.g. There is more water in the bottle. 瓶子里的水更多了。 e.g. We have more challenges. 我们有更多的挑战。【例1】Will there _ any paper money in 100 years?No，_. Ahave；there wontBbe；there wont Chave；they wontDbe；they wont点拨：根据问句中的there可知是考查there be句型；其简略否定答语也用there。答案：B【例2】Well try our best to do the work with _

18、money and _ people. Afew；little Ba few；a little Cless；fewer Dfewer；less点拨：money是不可数名词，要用little及其有关的词或短语修饰；people是复数形式，要用few及其有关的词或短语修饰。句意为“我们将尽力用更少的资金、更少的人去完成这项工作”。答案：C【例3】根据汉语意思完成下句我想要更多水、更少的食物。I would like _ water and _ food.答案：more；less6.

19、为“污染；污染物”。 air pollution 空气污染 noise pollution 噪音污染 e.g. There is a lot of pollution in the air here.拓展：pollution的动词形式是pollute,意为“污染；弄脏”，其过去式为polluted，现在分词为polluting。 e.g. All these waste products are polluting the river.【例题】Now _ is very serious.Some rivers and lakes are _.Apollution；polluteBpollute

20、d；pollutionCpollution；polluted Dpollute；polluted点拨：浏览题干可知，第一空在句中作主语，故用名词pollution；第二空在系动词are后，故用形容词polluted；pollute是动词。句意为“现在污染很严重。一些河流、湖泊被污染了”。 答案：C7.Whats your prediction about the future?future名词，意为“将来；未来”。常用短语：in the future意为“在将来，以后”，特指将来的某一时刻。 e.g. Who knows what will happen in the future?拓展：in
