几个关于英语 sb do,doing,to do的动词词组

see sb _/_(好像do和doing都可以,)
watch sb _
hope sb _

请回答完整谢谢咯

优质解答

must be sb doing 某人必须做.
see sb do是全过程,doing是看见某人正在做
watch sb 同上
hope to do sth,不能用hope sb to do sth句型 可以是hope +that 同位语从句.
如 His hope that he will have a large house one day is not impossible.
expect sb to do sth,希望某人可以做某事
