2 I haven't seen _______ this since I collected stamps.
A as old as a stamp as B so an old stamp as
C stamp as old as D as an old stamp as
答案是A 我不懂
答：我也不懂,因为题目抄错了,as ...as...怎么会有三个as呢?原题应该是：
I haven’t seen＿＿＿＿＿this since I collected stamps.
A.as old a stamp as B.so an old stamp as
C.stamp as old as D.as an old stamp as
这样选A就对了.
A项=I haven't seen a stamp as old as this .
其实A项如果将as改为so 更顺口一些,你不觉得吗?
B、D项是old与不定冠词词序错了.C项前加个a就对了.
