There be句型

(1)There be句型主要用以表達“某處(某時)有某人(某物)。”其基本結構為“There be+某物(某人)+某地(某時)”其中there是引導詞,沒有詞義;主語是be後面的名詞, be是謂語動詞,在一般現在時中be只用is和are兩種形式。下面這首歌訣可幫你巧記there be句型結構:

There be放句首,主語跟在後。地、時放句末,強調置前頭。There is a book on the desk. 有時為了強調地點,也可把介詞短語放在句首。如:On the desk there is a book.

(2)There be句型中的be動詞如何確定呢?請先看看下面這首歌訣:

Be動詞,有三個,am,is還有are。“There be”真特別,不留am只留倆,那就是is還有are。要用is還是are,須看其後的名詞是單數還是複數。若是單數或不可數名詞用is,否則就用are。如:

①There is a tree behind the house.

②There is some water(水)in the bottle(瓶子).

③There are some pears in the box.

(3)注意:如果“be”後的`主語是由and連接的兩個或兩個以上的名詞,那麼be的形式要遵循“遠親不如近鄰”的原則。也就是説,“be”的形式是由與它最近的那個名詞來確定的。若那個名詞是單數或不可數名詞要用is,是複數就用are。如:

①There is a book and some pens on the floor.

②There are some pens and a book on the floor.
