选择题
---Was it under the tree ____ you were away talking to a friend?
--- Sure. But when I got back there, the bike was gone.
A.that
B.where
C.which
D.while
答案
答案:D
此题很容易误以为是强调句型而选A。做好此题关键是正确理解句中的it的意思。从上下文的语境来看,it 应是代词,指代the bike,故用while 引导时间状语。句子可以理解为:“当你离开去同朋友谈话的时候,你的自行车是在这树下吗?”“当然,但当我回来时,自行车就不见了。”故选D。
