would to do sth和 would do sth

Question

不知道哪个是对的。还有，would有别的固定搭配吗？

Answer 1

would do sth对的 would是助动词would无词义，是will的过去形式，与动词原形构成过去将来时，用于第二、第三人称，例如：
　　He said he would come.　他说他要来。
　　比较：
　　"I will go," he said. 他说："我要去那儿。"
　　变成间接引语，就成了：
　　He said he would come.　
　　原来的will变成would，go变成了come.。

Answer 2

would do sth是对的还有would like 想要等固定搭配

Answer 3

would do sth= will do sth= would like to do sthwould 还可以跟rather 连接，就是would rather do sth than。。。
