Question

—Where did you pick up the stamp?
—It was at the post office ________ we worked in the summer vacation.

A．that	B．where
C．which	D．when

Answer 1

B

B 考察定語(yǔ)從句和強(qiáng)調(diào)句型。Where引導(dǎo)定語(yǔ)從句 ，在從句做地點(diǎn)狀語(yǔ)，修飾先行詞the post office，這是強(qiáng)調(diào)句的省略形式，句子補(bǔ)充完整是It was at the past office where we worked in the summer vacation that I picked up the stamp。強(qiáng)調(diào)的是整個(gè)定語(yǔ)從句部分。
