题目

I have reached a point in my life where i am supposed to make decisions of my own.为什么要选填
where?请详解、

答案

你好,你这个句子是由以下两个句子复合而成的.
I have reached a point in my life
I am supposed to make decisions of my own in my life
他们相同的部分是 in my life,所以in my life 是先行词.
从句中就要有个引导词来替代 in my life.并且连接主句与从句.那就是where这个关系词.
where = in my life. 是因为my life是一个名词,在从句中可以用which代替,
就成了 in which,而in which 是等于 where的,所以这里用where.
当然这里也能写 in which.
如果不明白还可以继续追问~如果对您有帮助请采纳~谢谢~
