There be句型是小學(xué)英語教學(xué)中的重要內(nèi)容。表示某處存在某(物)人。基本結(jié)構(gòu)為“There be +某物(某人)+某地(某時)”。 Be動詞的單復(fù)數(shù)必須依主語的變化而變化。單數(shù)is,復(fù)數(shù)are 如: There is a table in the room. 房間里有一張桌子。 There are some birds on the tree. 樹上有很多鳥。 一、 There be句型的結(jié)構(gòu): 1.(一)There is+單數(shù)可數(shù)+地點狀語 例:There is a ruler on the desk. 書桌上有一把尺。 (二)There are+復(fù)數(shù)主語+地點狀語 例:There are four apples on the tree. 樹上有四個蘋果。 There are some flowers in the park. 公園里有許多花。 (三)there is + 不可數(shù)名詞 +地點狀語 (即使有some 也是 單數(shù)) 例:There is some water in the bottle. 瓶子里有一些水。 (水是不可數(shù)名詞) 2. There be選擇就近原則: There be句型的就近原則是There be句型中語法項目的重點考點。There be句型中be動詞的單復(fù)數(shù)形式由最挨近的一項的單復(fù)數(shù)決定。 如:There is a pen, two books and many pencils on the desk. 在本句中盡管有鋼筆、書和鉛筆,但是由于離be動詞最近的一項是單數(shù)a pen,因此,be動詞用單數(shù)is。 二、There be 句型的疑問句及回答 (一)There be 句型的疑問 1. 在“There is/are...”的疑問句中,要把Be動詞放在there之前,并將句號變問號。難點:句中出現(xiàn)的some要改成any。 2. 肯定回答為:Yes, there is/are. 3. 否定回答為: No, there isn’t/aren’t. 例句 可數(shù)名詞單數(shù) 1. 肯定句There is an apple on the tree. 疑問句 Is there an apple on the tree? 肯定回答: Yes, there is. 否定回答: No, there isn’t. 可數(shù)名詞復(fù)數(shù)2. 肯定句There are five pens on the desk. 疑問句Are there five pens on the desk? 肯定回答: Yes, there are. 否定回答 No, there aren’t. 不可數(shù)名詞的時候 3. 肯定句 There is some water in the cup. (水是不可數(shù)名詞) 否定句 Is there any water in the cup? 肯定回答: Yes, there is. 否定回答: No, there isn’t. 三、There be 句型的否定形式 (一)There be 句型的否定: 否定形式只要在be動詞后面加not即可,is not =isn’t are not= aren’t 但要注意的是句中如果出現(xiàn)some則改成any. 1.There is a knife in the kitchen. 否定:There is not a knife in the kitchen. 2.There are five apples on the tree. 否定:There are not five apples on the tree. 3.There is some ink in the bottle. 否定:There is not any ink in the bottle. (ink是墨水,不可數(shù)名詞) 4.There are some birds singing in the tree. 否定:There are not any birds singing in the tree.
