1、Unit 4There be句型的用法 一、構(gòu)成There be .句型表示的是 “某處有(存在)某人或某物”，其結(jié)構(gòu)為There be (is，are，was, were )+名詞+地點(diǎn)狀語(yǔ)。 There are fifty-two students in our class.There is a pencil in my pencil-case.There was an old house by the river five years ago.二、各種句式 否定句：There be句型否定句式的構(gòu)成和含有be動(dòng)詞的其它句型一樣，在be后加上“not”。也可用“no”來(lái)表示。即：no +

2、n.（名詞）= not aanany + n.（名詞）。 There is an orange in her bag.There isnt an orange in her bag.There is no orange in her bag.注意：no + n.（可數(shù)名詞單數(shù)）= not aan + n.（可數(shù)名詞單數(shù)）；no + n.（可數(shù)名詞復(fù)數(shù)）= not any + n.（可數(shù)名詞復(fù)數(shù)）；no + n.（不可數(shù)名詞）= not any + n.（不可數(shù)名詞）。 There is some juice in the bottle.There isnt any juice in the b

3、ottle.There is no juice in the bottle.一般疑問句：There be結(jié)構(gòu)的一般疑問句變化只需把be動(dòng)詞移到句首，再在句尾加上問號(hào)即可。 There is something new in todays newspaper.There isnt anything new in todays newspaper.Is there anything new in todays newspaper?特殊疑問句：There be句型的特殊疑問句有以下三種形式： 對(duì)主語(yǔ)提問：當(dāng)主語(yǔ)是人時(shí)，用 “Whos + 介詞短語(yǔ)?”；當(dāng)主語(yǔ)是物時(shí)，用 “Whats + 介詞短語(yǔ)?”

5、提問方式： 如果主語(yǔ)是可數(shù)名詞，無(wú)論是單數(shù)還是復(fù)數(shù)，都用“How many +可數(shù)名詞復(fù)數(shù) + are there + 介詞短語(yǔ)？”表示：There are twelve months in a year. How many months are there in a year?There is only one book in my bag. How many books are there in your bag?There is a cat in the box.

There were many people in the street yesterday. 如果有兩個(gè)或兩個(gè)以上的名詞作主語(yǔ)，be動(dòng)詞要和最靠近它的那個(gè)主語(yǔ)在數(shù)上保持一致，也就是我們常說的 “就近原則”。例如：There is an orange and some bananas in the basket.
