此题考你两个语法点:
【1】介词without,其后加动词的现在分词,即-ing形式,是故,排除D选项;
【2】被动语态,此句逻辑主语为happy times 美好的时光,应该是不被注意地流逝,be noticed,结合【1】,可知答案是【without being noticed】.
期待再次与你交流英语学习!

首先without是介词 后面一定要接名词或动名词
所以排除D
然后因为happy time是被notice
所以是被动语态be noticed
综上 应该是being noticed

Happy times是被注意,所以用被动语态,without是介词,后跟进行词,所以选B

22. Happy times usually pass quickly without _______.
A. noticing B. being noticed C. having noticed D. to be noticed
选项是C
问题很简单,因为without是介词,介词后面跟名词或动名词。Happy times 没有【被注意】用动名词的被动形式

notice happy times.所以当happy times 做主语的时候要用被动语态,此时without 为介词,所以要用being noticed~欧了!

without doing,被注意到,选被动
