all we can do to help him is that give him some money这句话会因为从句中没有主语而成为错句吗?

all we can to 很常见的说法是：We should do all we can to help those who are in trouble.为什么不是：all we can do to help..all that we can to help..all that we can do to help..what we can to help..what we can do to help.. all we can do is to 为什么能用两个动词 is 跟 do all we can do is to 为什么能用两个动词我是说 do 跟 is all that we can do is to do sth.不是缺谓语吗?that we can do 做all的定语,如果省去定语就是all is to do sth,is to do 是非谓语,请问这个句子为什么正确? 英语作文We Can All Do It We must do all we can to help those in trouble.中的 all 是否可改为 whatever What ( on earth)can we do to improve our environment.这一空能用after all 代替么? We don' t need you anymore go to hel I guess all we can do is to stay home and watch TV.句中all 可换成anything吗?
