12. lack可用做形容词吗?
The boss praised the young man for his hard work, though heexperience.
A. is lack ofB. is lacking inC. lacks ofD. is lacking of
此题答案选B,be lacking in是习语,意为“缺乏”,其后通常接experience, frankness, courage等抽象名词。选A是错误的,因为lack可用做名词和动词,但不用做形容词;选C是错误的,因为lack用做动词时,它是及物动词,其后不用介词(注:用做名词的 lack后可接介词of);选D是错误的,因为没有be lacking of这个搭配。
