7、re will be robots in peoples homes? 本句是一個(gè)含有賓語(yǔ)從句的主從復(fù)合句，Do you think是主句，there will be.是賓語(yǔ)從句。如果do you think放在句中，則為插入語(yǔ)，常放在疑問(wèn)句之后，結(jié)構(gòu)為：疑問(wèn)詞+do you think+主語(yǔ)+謂語(yǔ)+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意為“將有，會(huì)有”，是there be句型的一般將來(lái)式，其否定形式是there wont

8、be.,一般疑問(wèn)句形式是Will there be.?有時(shí)可以與There is/are going to be.相互轉(zhuǎn)換。 e.g. There will be a film this evening. 否定句，疑問(wèn)句，答語(yǔ)拓展：there be句型的一個(gè)重要用法是“就近一致”原則，即謂語(yǔ)動(dòng)詞be和最靠近它的名詞在數(shù)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與have/has的區(qū)別：前者表示某地存在某物；后者表示“擁有”

9、的意思。二者有時(shí)可以互換。 e.g. Our school has twenty classes. =There are twenty classes in our class.(2012.江蘇揚(yáng)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

I dont think you can go there by bus.思考

11、：其反意疑問(wèn)句的變法every此處用作形容詞，意為“每個(gè)的，每一”。 e.g. Not every horse can run fast.辨析：every與eache.g.Every teacher knows her. There are lots of trees on each side of the road. Each of us has a dictionary. every形容詞指三者或三者以上范圍中的“每一個(gè)”，側(cè)重總體，不能單獨(dú)使用each形容詞指兩者或兩者以上中的“每一個(gè)”，側(cè)重個(gè)體代詞可作主語(yǔ)或賓語(yǔ)，其后可跟介詞of every與each的區(qū)別every用來(lái)表整體，eac

12、h用來(lái)表個(gè)別，each最低需是兩，every最低需是三。every作主用單數(shù)，each可單也可復(fù)，作主、定用單數(shù)，其他情況用復(fù)數(shù)。3Books will only be on computers，not on paper. 書(shū)只會(huì)在電腦上，而不會(huì)在紙上。 paper n. “紙，紙張”，是不可數(shù)名詞。表示“一張紙”用a piece of paper，“兩張紙”用two pieces of paper。e.g. There is a piece of paper on the table.桌子上有一張紙。paper n. “試卷”，作可數(shù)名詞，有復(fù)數(shù)形式。 e.g. I lost a histo

He started on Sunday and arrived in Beijing after three days.in用來(lái)表示以現(xiàn)在為起點(diǎn)的將來(lái)某一段

15、時(shí)間之后，后接時(shí)間段用于將來(lái)時(shí)after既可接時(shí)間點(diǎn)又可接時(shí)間段用于過(guò)去時(shí)5There will be fewer people.將有更少的人。本句是含有there be句型的一般將來(lái)時(shí)的簡(jiǎn)單句。 結(jié)構(gòu)為：There will be主語(yǔ)其他。其否定形式是在will 后加not；疑問(wèn)句形式是把will 提到there前。簡(jiǎn)略肯定回答：Yes，there will.簡(jiǎn)略否定回答：No，there wont.e.g. There will not be enough room for people to live in. 將沒(méi)有足夠的給人住的空間。e.g. Will there be fewer a
