七年級英語Therebe句型講解和練習(xí)

1、There be 句型There be 句型1、定義：There be結(jié)構(gòu)主要用以表達(dá)“某地有某人(某物)”。其基本句型為“There be +某物或某人(主語)+某地”。2、be動詞的選擇：There be結(jié)構(gòu)中的謂語動詞be (is / are )在人稱和數(shù)上應(yīng)與 其后的主迫保持一致。主語是不可數(shù)名詞或單數(shù)可數(shù)名詞時(shí)用is ;主語是復(fù)數(shù)時(shí)用are。3、具體結(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.E.g. There is a desk in the classroom.在教室里有一張桌子。(2) There are +復(fù)數(shù)名詞+地點(diǎn)犬語.E.g. There

2、are 5 apples in the box.盒子里有五個(gè)蘋果?？谠E：“有”字放前面，有“啥”放中間；時(shí)間地點(diǎn)放后面；單數(shù)is, 復(fù)數(shù)are注意be的兩變化。4、句型變化：(1) 、否定句：there be 的否定式通常在 be后加not。E.g. There is a bike under the tree.樹下有一輛自行車。There isn't a bike under the tree.E.g. There are 2 little girls in the room.在房間里有兩個(gè)小女孩。There aren't 2 little girls in the room

3、.(2) 、一般疑問句及其答語：1 、一般疑問句：把 be動詞提前，首字母大寫，句末用問號即可。2 、回答時(shí)，“用什么問，就用什么答"，用Is / Are there來提問，就用there is/ are-來回答。否定回答：No, there isn't / aren't.樹上有兩只貓。肯定回答：Yes, there is / are.E.g. 1、There are two cats in the tree.Are there two cats in the tree?Yes, there are. No, there aren't.2、 There is

7、d some books on the desk.書桌上有兩支鉛筆、一支鋼筆和一些書。3 .There some books , two pencils and a pen on the desk.書桌上有一些書、兩支鉛筆和一支鋼筆。課堂練習(xí)：There milk and eggs on the table .在桌子上有牛奶和雞蛋。There eggs and milk on the table.7、 “there be ” 和 “have” 的區(qū)別There be表示“存在有“ ；have （has）表示“所屬有”。他們都翻譯為“有”，但具 體用法不相同,且兩種結(jié)構(gòu)不能同時(shí)合用。E.g.1、

8、I have a book .我有一本書。（注：書歸我所有，我是書的主人。一所屬有）2、There is a book on the desk .在桌子上有一本書。（注：書只是存在于桌子上，但書不屬于桌子所有。一存在有）8、常見的的介詞和介詞短語:on 在 上面后面 near 在. 附近on the floor在地板上near the zoo在動物介詞：at 在. in在 里面under在 下面 behind 在介詞短語舉例：at home 在家in the box 在盒子under the tree 在樹下 behind the door 在門后面園附近in front of在前面（2）變式
