每次看到墨尔本文波雅思学员的有些写作错误，我就痛心疾首，感觉自己在一遍一遍的改一样的错误。我就希望汇集一个常见经典错误集，让每一个要考7分写作的同学先读读。今天墨尔本文波雅思就给大家讲下lack 这个词：
lack / læk; læk/ v
1.及物动词[不用於被动语态] 没有（某事物）; 缺乏; 不足:
lack creativity, self-discipline, courage 缺乏创造性﹑ 自制力﹑ 勇气 *
They lacked the money to send him to university. 他们没钱送他上大学. *
What he lacks in experience he makes up for in enthusiasm. 他热心工作以弥补其经验的不足.
2. 不及物动词：[不用於被动语态] ~ for sth (fml 文) need sth 需耍某事物:
They lacked for nothing,他们无所需求（已应有尽有）.
(idm 习语) be `lacking 缺:
Money for the project is still lacking. 进行这个项目的钱还没有着落.
be lacking in sth not have enough of sth 不足; 不够: be lacking in warmth, courage, strength 缺乏温暖﹑ 勇气﹑ 力气 *
The film was lacking in pace. 这部影片不紧凑.
> lack n [U, sing] absence or shortage (of sth that is needed) （所需事物的）缺乏, 短缺: a lack of care, money, water 缺乏关心﹑ 金钱﹑ 水 *
The project had to be abandoned for lack of funds. 工程因资金匮乏只得放弃.
文波老师点评：
lack 这个词既是及物动词，也是不及物动词，而且也是名词。所以很多同学用混了。最常见的错误是 be lack of…. 四不像。还有就是用做名词的时候是不可数。一般为 for lack of+名词 但是也见过a lack of…
简单记为：
Sth lacks sth
Sth is lacking in sth
Sth fails for a lack of sth/lack of sth(复数).
经典搭配：
a lack of planning on your part 你缺少规划！
a lack of boundaries invites a lack of respect 缺少界限就缺少尊重！
a lack of compassion can be as vulgar as an excess of tears 缺少同情和眼泪泛滥一样粗陋。
