Three questions about English grammar in senior high school ~ ~

1. When the subject clause contains do, the slogan behind be is: (to) Do something.

What does Yang want ... to be shared? ...

2.a could have been, but the subject is lovers = men&; That woman, so I repeated it.

Getting married means the future from time to time, and engagement is for the future marriage.

3。 I intend to give it to him. I was going to return it yesterday, but I couldn't (so I didn't return it in time)

What I intended to do in the past, but I didn't actually do it.

It means a virtual future. But here is what I didn't do yesterday.
