最好有得出答案的原因，

1.how----- ----- feel to be back to school again after graduation for 20 years?Ado you B.does that c,did you d,does it2.Tom sat under a tree and seeing his friend,---------up in no time.a.to stand b.standing c.stood d.would stand3.---can i join your
1.how--do you(A现在,而且you 是用do的=》你有什么感觉)-- feel to be back to school again after graduation for 20 years?
Ado you B.does that c,did you d,does it
（其实这题应该也可以用D,如果用D的话意思就会变成回校的感觉是什么）
2.Tom sat(过去） under a tree and seeing his friend,---stood（B.过去）--up in no time.
a.to stand b.standing c.stood d.would stand
（应为句子是过去式所以后面的也应该是用过去）
3.--can i join your club,dad
---you can when you --get（A)---a bit older
a.get b.wlii get c.are getting d.will have got
（我觉得应该还是A会好一点,》你大一点就可以了）
4.---I'm sorry to keep you waiting .
---oh,not at all.I-----have been(A)----here only a few minutes.
a have been b.had been c.was d.will be
（不可能是过去或者是未来所以只有A可选）
5.I need one more stamp before my collection ---is completed (D).--
a.has completed b.completes c.has been completed d.is completed
（我是需要一个邮票就完成我的收藏了）
