I do a lot of (work to) help people.括号里为什么不能填jobs或jobs to?

I have a lot of work to do,变为被动 i do a lot of traveling in my work i have a lot of work to do.否定句 i ( )have ( )work to do. I have a lot of work to do为什么不是 I have a lot of work to be done i have a lot of work to do to do是句子里的什么成分 I have____ to do this evening .A.a lot of works B.many work c.a lot of work D.some work I have ____to do this evening.A.many work B a lot of work C.some work D.a lot of works 我觉得不对 I do a lot of work every day.改成以He为主语的句子 i have a lot of work to do.这里工作是被做 为什么不用to be done. i have rather a lot of work to do请问,rather在这里是什么意思? I have (lot of ) work to do this week.a,many b,some c,much This weekend,I still have a lot of work 【do】.适当形式填空 I've got to lot of work to do I have a lot of homework-----(do) Robots can do a lot of ____(danger) work. I have a lot of work to do this week,What I need is more time为什么这里用What I had__to do last night.A.a lot of works B.some works C.many works D.a lot of work 刚学很弱智的.2I do a lot of work every day.换成He开头的主语就是 He does a lot of work every day.(但三do变does吧)可是如果是过去式.I did a lot of work yesterday.那么如果用He开头做主语.应该怎么变?He did a lot of
