3、考察點(diǎn)】一 there be 句型根本情況1定義：There be句型表示某處存在某物或某人。2. 構(gòu)造：1 There is +單數(shù)可數(shù)名詞/不可數(shù)名詞+ 地點(diǎn)狀語(yǔ). 2 There are +復(fù)數(shù)名詞+地點(diǎn)狀語(yǔ).注意：there是引導(dǎo)詞，在句中不充當(dāng)任何成分，翻譯時(shí)也不必譯出。句子的主語(yǔ)是某人或某物，謂語(yǔ)動(dòng)詞be要與主語(yǔ)某人或某物的數(shù)保持一致。當(dāng)主語(yǔ)是兩個(gè)或兩個(gè)以上的名詞時(shí)，謂語(yǔ)動(dòng)詞要與跟它最近的那個(gè)名詞一致。如： There is a bird in the tree. 樹(shù)上有一只鳥(niǎo)。 There is a teacher and many students in our classro

4、om.我們教室里有一位老師和許多學(xué)生。 There are two boys and a girl under the tree. 樹(shù)下有兩個(gè)男孩，一個(gè)女孩?！究疾禳c(diǎn)】二there be 句型的各種句型轉(zhuǎn)化。1.變成否認(rèn)There be句型的否認(rèn)式的構(gòu)成和含有be動(dòng)詞的其它句型一樣，在be后加上not或no即可。注意not和no的不同：not是副詞，no為形容詞，not a/an/any + n. 相當(dāng)于no+ n.。 如： There are some pictures on the wall. There aren't any pictures on the wall. =Ther

5、e are no pictures on the wall. There is a bike behind the tree. There isn't a bike behind the tree. =There is no bike behind the tree.2.變成一般疑問(wèn)句 There be句型的一般疑問(wèn)句變化是把be動(dòng)詞調(diào)整到句首，再在句尾加上問(wèn)號(hào)即可。但同時(shí)要注意：當(dāng)肯定句中有some時(shí)，要將其改為any否認(rèn)變化也一樣。如：There is some water on Mars. Is there any water on Mars? There are some fi

6、sh in the water. Are there any fish in the water? 3.特殊疑問(wèn)句1對(duì)主語(yǔ)提問(wèn)：當(dāng)主語(yǔ)是人的時(shí)候，那么用who 引導(dǎo)，當(dāng)主語(yǔ)是物的時(shí)候，那么用what 引導(dǎo)。注意：無(wú)論原句的主語(yǔ)是單數(shù)還是復(fù)數(shù)，對(duì)之提問(wèn)時(shí)一般都用be的單數(shù)形式答復(fù)時(shí)卻要根據(jù)實(shí)際情況來(lái)決定。如： There are many things over there. What's over there? There is a little girl in the room.Who is in the room? 2對(duì)地點(diǎn)狀語(yǔ)提問(wèn)：那么用where 引導(dǎo)。如： There is

7、a computer on the desk. Where is the computer? There are four children on the playground. Where are the four children? 3對(duì)數(shù)量提問(wèn),一般有兩種句型構(gòu)造： How many+復(fù)數(shù)名詞+are there+介詞短語(yǔ)？ How much+不可數(shù)名詞+is there+介詞短語(yǔ)？【考察點(diǎn)】三there be 句型的時(shí)態(tài)。 be可以有如今時(shí)there is/are、過(guò)去時(shí)there was/were、將來(lái)時(shí)there is/are going to be或there will be和完

8、成時(shí)there have/has been；還可用there must be ,there cant be, there used to be等。 如： -There is going to /will be a concert this evening. -Yeah. Exciting news! There is going to / will be a football match on TV this evening. 【考察點(diǎn)】四there be 句型的主謂一致 There be 構(gòu)造中的be動(dòng)詞要和后面所跟名詞保持一致,遵循就近原那么。 如：There isnany rice in

9、 the bowl. There is a teacher and many students in our classroom. There are two boys and a girl under the tree. 【考察點(diǎn)】五 there be 句型反意疑問(wèn)句的構(gòu)成：be not there? 如：There is some milk in the bottle, isn't there? 【易錯(cuò)點(diǎn)】六 there be 句型與have句型的區(qū)別1 There be 句型和have都表示“有的含義。區(qū)別如下：There be表示“某處存在某物或某人；have表示“某人擁有某物

10、/某人，它表示所有、擁有關(guān)系。 如： He has two sons. 他有兩個(gè)兒子。There are two men in the office. 辦公室里有兩個(gè)男人。2當(dāng)have表示“包括、“存在的含義時(shí)，There be 句型與其可互換。如： A week has seven days. =There are seven days in a week. 一個(gè)星期有七天。三、例題精析【例題1】【題干】David, there _ a dictionary and some books on your desk.
