关于一个英语的句式

Of the millions who saw Haley’s comet in 1986, how many people will live long enough to see it return in the twenty-first century.
1986年看见哈雷慧星的千百万人当中,有多少人能够长寿到足以目睹它在二十一世纪的回归呢?

Return在这为什么没 to or doing.
When should use doing, and when should use to do.
Is return a noun or verb?

When a infinitive is used after the verb see, watch, observe, notice, look at, feel, hear, listen to, make, have, or let, and sometimes after help, the infinitive must be used without "to". In the setence above, "to see it return" is one of such a structure, so "to" must be missed.
用汉语说就是当动词不定式用于上述所列动词后作宾语补足语时,to必须省去。
非谓语动词作补足语有三种情况,以see为例:
1. see sb. do sth.看到某人做过某事;
2. see sb. doing sth. 看到某人正做某事;
3. see sth. done (by sb.)看到某事被做了。
注意。省to的情况仅限于上述动词,不能类推。告诉你一句口诀:一“感feel”二“听see, listen to”三“使make, have, let”五“看see, look at, watch, notice, observe”半个“帮助help(即:help do和help to do都对)”。

see sb./sth. do sth.按照字面意思这句话是一般陈述式~所以用动词原形。
当然也有see sb. doing sth. 看到某人正在做某事~

verb.
如果表示名词的话要改成see its return.
see sb./sth. do/doing 都可以,doing更强调看到动作正在进行。
至于什么时候用doing,什么时候用to do,这跟前面的动词有关系,有很多,需要自己平时积累,跟这道题没什么关系。
