Let's go and buy some CDs,---?Dood.A.will you B.shall we C.d

B是正确选项.这里涉及到will you和shall we如何正确使用的问题.
以Let开头的祈使句,构成反意疑问句时,除Let’s用shall we构成反意疑问句外,其它均用will you.注意当前面是Let us的时候,后面需要使用will you,不要混淆.
例:
Let the boy go first,will you?让那男孩先走,好吗?
Let’s take a walk after supper,shall we?晚饭后,我们去散步,好吗?
Let's go and listen to the music,shall we?
Let us wait for you in the reading-room,will you
