英語中Lack的用法
請問lack,a lack of,be lacking in這3個詞有什么區(qū)別.
我知道lack可以做動詞和名詞.a lack of是個名詞詞組,并且a可以省略.be lacking in是動詞短語.
它們3個的用法到底該怎么用.
比如:
1;Those old people___a general understanding of the present situation.
A:lack of B:are lacking of
C:lack D:in lack of
就這道題而言,我認為AC都可以的.
2:The couple died because of___oxygen when bathing.
A:lack B:a lack
C:a lack of D:a lack for
我也覺得AC都可以.怎么回事呢.
希望英語好的可以盡快回答我.
3:Though___money,hie motehr managed to send him to university
A:lacked B:lacking of
C:lacking D:lacked in
選什么額,這個題根本不知道了.
