你要表达的这个句子是什么意思?是告诉我们一本好书必须去读它吗? good book是好书的意思,前面又加个well就错了,good在这是形容词修饰book,well放在这也想做形容词吧,两个形容词明显不行,所以放这句子里就错了. 可以把well去掉,变成to tell a good book must be resd. 这是well做形容词的用法: Is she well enough to travel? 她身体康复,能够旅行了吗? We're very well where we are. 我们处境很好. It would be well to start early. 最好还是早点动身.
