非谓语动词问题 急非谓语动词我主要有3个疑问 1非谓语动词如何起到省略句子的作用了 请举例说明2动名词和非谓语动词 能同

1.I meet you and it is nice .用不定式做非谓语动词,这句话变成 It's nice to meet you.简介通顺.
2.可以同时出现.I would love to go shopping....to go...就是非谓语动词,...shopping是动名词.
3.以上两个例子都非常口语.还有其他一些常用的对话：
I am going to meet my friend.( to meet )
Working hard is my family tradition.(Working hard)
There is a shop selling flowers.（selling）
非定语从句把几个简单句组合在一起.
