He was the first to pass the finishing line.分析英语句子成分.
He was the first to pass the finishing line.这句里的to pass做什么成分
There was a police officer standing by me.standing 做什么成分

答案

很乐意给你解答我比较擅长的英文：
这两个句子成分是一样的,都叫定语,定语是用来修饰表语或宾语.比如to pass the finishing line就是修饰was the first的,也可用中文理他是第一名.是什么的第一名呢?是第一个过线的.
下面句话也是这么理解.那个警察是站在我身旁的警察.
希望能帮上你!也欢迎追问,愿意为你解答!
