n.(常与of连用)缺乏;需要 there is no lack of vegetable. 蔬菜不缺.the lack of rain aggravated the serious lack of food. "由于干旱少雨,缺粮问题更加严重." vt.是及物动词,直接接所缺乏的东西就可以:缺乏;不足;没有 he lacks courage.

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.

lack 作动词时,后面直接加名词,没有任何介词,所以第一道题应该只能选A.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),所以第二道题应该只能选A.而lacking是形容词,并且有词组:be lacking in sth. 也表示缺乏某物,可是第三道题可以填“lacking in”,可惜没有.那么只能用动词lack后面直接加名词这种形式,而且,由于无主语,因此,要用v.ing形式,所以本题应选C.
