动词难点(请崔)
解题思路:
解题过程:
补充说明lack的用法: Lack缺乏,没有
Lack+of+名词: The plants died for lack of water.
Lack+名词: We lack the strength to walk any further.
短语: be lacking:欠缺、缺: Money was lacking to complete the building.
Be lacking in缺乏(某种品质、特点等),不够: He is not lacking in intelligence.
Lack for 缺(多用于否定句) She does not lack for friends.
作动词时,后面直接加名词.
lack 作名词时,有词组(the) lack of sth. 表示缺乏某物,此时lack不可数(因为表示抽象概念),而lacking是形容词,并且有词组:be lacking in sth. 也表示缺乏某物,第2道题可以选“lacking in”。那么用动词lack后面直接加名词这种形式,而且,由于the area 与lack成主谓关系,因此,要用v.ing形式,所以本题如果把作为动词使用,可选B,如果作为形容词,可选C.

lack
最终答案:略
