Let,s return the book to the library.A shall we B will you C won,t we D don,t we 选什么WHY
选A,
因为前面的陈述句是Let us, 所以后面的反义疑问句就是 Shall we?
再问： 什么情况用BCD ?
再答： We have the same hobby, don't we? 前面是肯定句，我们怎样怎样。 Open the door, will you? 前面的句子一般是祈使句，请你，麻烦你做某事 won't we 不常见
再问： 再详细点么
再答： 当陈述部分是祈使句时，疑问句要根据语气来表达，分三种情况： 1）一般情况下用will you 或 won't you。 e.g. Give me a hand,will you? Leave all the things as they are,won't you? 2)以Let's开头的祈使句，疑问句用shall we;以Let us或Let me开头的祈使句，问句用will you。 e.g. Let's go out for a walk, shall we? Let us go out for a walk, will you? Let me help you,will you? 3)当陈述句是否定的祈使句时，问句可用will you 或 can you 。 e.g. Don't make much noise,will/can you?
