教學目標 1、講授there be句型的定義及結構 2、正確使用there be句型的肯定,否定及一般疑問形式
教學過程 today we’ll learn “there be”. 一:there be句型的定義及結構 1、定義:there be句型表示某地有某物或某人。 2、結構:一共分為三種 (1) there is +單數可數名詞+ 地點狀語. there is a book on the desk. there is an umbrella in the bag. (2) there is +不可數名詞+ 地點狀語. there is some milk in the cup. there is some sheep and a cow on the farm.
(3) there are +復數名詞+地點狀語.
there are four chairs in the living room.
there are some birds and a balloon in the sky. 從以上例句中我們可以發現there是引導詞,在句中不充當任何成分,翻譯時也不必譯出。句子的主語是某人或某物,be動詞表示“有”,謂語動詞be要與主語(某人或某物)的單復數保持一致。some既可用于可數名詞也可用于不可數名詞。 二:there be 句型的變化 1:變成否定句 there be+not+某物+地點狀語。 there be句型的否定式的構成和含有be動詞的其它句型一樣,在be后加上not. 注意,is not的縮寫是isn’t,are not的縮寫是aren’t. 當肯定句中有some時,要將其改為any(疑問變化也一樣)。 there isn’t a book on the desk. there isn’t an umbrella in the bag. there isn’t any milk in the cup. there isn’t any sheep and a cow on the farm.
there aren’t four chairs in the living room.
there aren’t a lot of birds and a balloon in the sky. 2:變成一般疑問句 ,. there be句型的一般疑問句變化是把be動詞調整到句首,再在句尾加上問號即可。 基本句型:be + there+某物+地點狀語? 回答:yes, there + be. \ no, there + be +not. - is there a book on the desk? -yes,there is. - is there an umbrella in the bag? -no,there isn’t. - is there any milk in the cup? -yes,there is. - is there any sheep and a cow on the farm?- no,there isn’t. -are there four chairs in the living room? -yes,there are. - are there a lot of birds and a balloon in the sky?- no,there aren’t.
