don,t walk on the grass,will you.為什么當(dāng)陳述部分是祈使句時(shí)，疑問(wèn)句要根據(jù)語(yǔ)氣來(lái)表達(dá)，分三種情況：
1）一般情況下用will you 或won't you。
Give me a hand, will you?
Leave all the things as they are, won’t you?
2)以Let's（聽(tīng)者包括在內(nèi)）開(kāi)頭的祈使句，前肯后可肯可否，疑問(wèn)句必須用shall we（shall只用于第一人稱(chēng)）;只有以Let us（聽(tīng)話(huà)人不被包括在“us”里面）或Let me開(kāi)頭的祈使句，問(wèn)句才用will you。
Let us know the time of your arrival, will you?
Let's try again, shall we?
Let me help you, will you?
Let’s have a look on your book，shall we？
3)當(dāng)陳述句是否定的祈使句時(shí)，問(wèn)句可用will you 或can you 。
e.g. don’t make much noise, will/can you?
