1. see/look at/watch/notice/observe/hear /listen to/feel/make/have/let/ 这些动词带不定式作宾补时，省掉to, 若这些动词以被动形式出现时，应加上to。动词help后面作宾补的不定式可省略to，也可加to。例：I saw him go upstairs. 被动形式是: He was seen to go upstairs.

如若主动变被动
该to一定要带着
例: I see him going upstairs.
He is seen going upstairs.

Have you anything to be sent?

I have a lot of work to do.
