we should do we can do to help forests.什么句式?为什么can 后面加的是to do
对不起，写错了，是we should do we can to help forests

这句话是个宾语从句~we should do something（what we can do to help forests）.我们应该做点什么的意思.要做的事情是指保护丛林,something就指的是保护森林.
你给出的句子省略了what~而句子中断句应该是we should do what we can do to help forests.最后的to do是指目的.

we should do we can do to help forests.什么句式?为什么can 后面加的是to d 为什么We can do what we can to help you . what do you think we can do to protect forests? 同义句we should do what we can do to help the poor.we should_ _ We think we should do whatever we can to help our school.该句中 We should do ____ _____ _______ we can to help people in tro We should do what we can （to help） them with their lessons. can't help but 后面加to do 还是do? We should do as much as we can___(help)poor children 为什么要加to can是情态动词但是为什么We should do everything we can 后面从句can单独使用? We want to know to help them.A.what can we do B.what we can We must do what I can to help him这里为什么要用to help
