1. 定義:There be句型表示某處存在某物或某人。
2. 結(jié)構(gòu):
(1) There is +單數(shù)可數(shù)名詞/不可數(shù)名詞+ 地點(diǎn)狀語.
(2) There are +復(fù)數(shù)名詞+地點(diǎn)狀語.
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。句子的主語是某人或某物,謂語動(dòng)詞be要與主語(某人或某物)的數(shù)保持一致。當(dāng)主語是兩個(gè)或兩個(gè)以上的名詞時(shí),謂語動(dòng)詞要與跟它最近的那個(gè)名詞一致。
eg. ① There is a bird in the tree. 樹上有一只鳥。
② There is a teacher and many students in our classroom. 我們教室里有一位老師和許多學(xué)生。
③ There are two boys and a girl under the tree. 樹下有兩個(gè)男孩,一個(gè)女孩。
3. There be句型與have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/某人”,它表示所有、擁有關(guān)系。 eg.
①He has two sons. 他有兩個(gè)兒子。
②There 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。
eg. A week has seven days. =There are seven days in a week. 一個(gè)星期有七天。
變臉一:否定句
There be句型的否定式的構(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.。例如:
There are some pictures on the wall. →There aren't any pictures on the wall. =There 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.
變臉二:一般疑問句
There be句型的一般疑問句變化是把be動(dòng)詞調(diào)整到句首,再在句尾加上問號(hào)即可,此為\"調(diào)整法\"。但同時(shí)要注意:當(dāng)肯定句中有some時(shí),要將其改為any(否定變化也一樣)?纯聪旅鎯删涫侨绾蝄"改頭換面\"的吧:
There is some water on Mars. → Is there any water on Mars?
There are some fish in the water. →Are there any fish in the water?
變臉三:特殊疑問句
There be句型的特殊疑問句形式有以下三種變化:
① 對主語提問:當(dāng)主語是人時(shí),用\"Who\'s+介詞短語?\";當(dāng)主語是物時(shí),用\"What\'s + 介詞短語?\"。注意:無論原句的主語是單數(shù)還是復(fù)數(shù),對之提問時(shí)一般都用be的單數(shù)形式(回答時(shí)卻要根據(jù)實(shí)際情況來決定)。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 對地點(diǎn)狀語提問:提問地點(diǎn)當(dāng)然用"Where is / are+主語?\"啦!例如:
There is a computer on the desk. → Where is the computer?
There are four children on the playground. →Where are the four children?
③ 對數(shù)量提問:一般有兩種句型結(jié)構(gòu):
How many+復(fù)數(shù)名詞+are there+介詞短語?
How much+不可數(shù)名詞+is there+介詞短語?
