写作基础题目A child's life is like a piece of paper.On it every pa

1.该句不可以改写成：A child's life is like a piece of paper that every passerby leaves a mark.
2.此题考查定语从句的关系词的用法和区别.
1）先行词为a piece of paper,而which可以代替它,并和介词on一起,在定语从句every passerby leaves a mark中充当地点状语.
即定语从句可以写为：on which every passerby leaves a mark
= on the piece of paper every passerby leaves a mark
= every passerby leaves a mark on the peice of paper
2）此题也可以改写成：where every passerby leaves a mark
即关系副词where = 介词on + 关系代词which
3.不过,在非正式场合如英语口语中,的确可以用that代替关系副词where/when/why等,但是如果书面考试,我认为不能得分.

that means a piece of paper
?every passerby leaves a mark paper?
That is not English.
Good luck.
NB: I really doubt it.
