Question

这两句英语有语法错误么
What did the book do to help people
Why we say the internet is useful but dangerous
这是我英语演讲的两个问题,原文没有问题,我自己写的怕出问题,所以来问问
骗分的自重,这关系到我的学分

Answer 1

第一句,book是不能do任何事的,所以应该是how does the book help people to.干吗干吗,或者in what way does the book help people to.(比如 to become more optimistic about life,或者之类的）.
第二句,可以做句子的一部分,比如 this is why we say the internet is useful but dangerous.如果自己成一个问句要改成 why do we say the internet is useful but dangerous.
