Answer 1

1.How
about用来询问，"……怎么样”。“那么你上次撞到了路灯柱的事又怎么说呢？”
2.
3.我的解释跟ywlff相反，be
going
to是早就计划好了的，如I'm
going
to
HongKong
tomorrow.我明天去香港
而will有可能是临时决定，所以这里要用will
4.Not
at
all可表示“不客气”，回答“谢谢”时使用。而此题用That's
right表示“没事，不介意”，更恰当。
5.Come
off
it!用于祈使句，要某人不再说不确之事，意为“别胡扯了！”
6.这里的put表示处于一种状态。
对话的意思是“你境况很好”“事实上我们是在艰难地交着房租呢”
