英语语法问题(老师或英语专业的同学请进)students are suffering from ( ) of free time.

Question

Believe it or not，both teachers and students are suffering from ( ) of free time. 请问括号里应该填lack还是lacking？？？
不胜感激！！！
请解释一下

Answer 1

填lack
这儿lack 是名词，从后面的of 也可以看出此处需要一个名词
lack 可以是名词也可以是动词“缺乏，没有，不足”
n. ：lack of sth
Vi. : be lacking in
eg. they reception of us was lacking in warmth
他们接待我们不热情
Vt. : lack + sth
eg. you lack courage

常用的还有lack for
you lack for money
你不缺钱用

Answer 2

用lacking
因为suffer from 后面一般接名词或动名词：suffer from sth 或 suffer from doing sth.

Answer 3

lack
不管你信不信，教师和学生都苦于缺乏空余时间。

Answer 4

应该lacking吧

Answer 5

lack。
