楼上的“sunnyleesun Lack”解答的非常好,
这里我为你补充lack的用法,应该算中学英语最常见也最主流的三种用法,望抽时间系统梳理一下：
【n.（名词）“不足”.通常用 “lack+of＋名词”.】
①A deficiency or anabsence:缺乏或没有；
②Something needed orwanted.欠缺的事物：缺乏或寻求的某物

food.没有食物,他再也坚持不下去了.
【vt.（及物动词）缺乏；不足；没有】
①To be entirelywithout or have very little of.缺乏：根本就没有或仅有一点

to illness.
(注：说lack不用于进行时是站不住脚的)
【vi.（不及物动词）还可作“缺乏,短少；不足；需要.常用进行时】
①To be wanting ordeficient:缺乏：处于匮乏或不足状态：

（注：这里把lacking处理为vi.,并没有作为adj.来得简单）
②To be in need ofsomething:需要：需要某物：
