Question

【題目】-- Did you have a discussion with him about the matter?

--- No. When I saw him, he________ his history project busily.

A. has prepared B. prepares C. was preparing D. prepared

Answer 1

【答案】C

【解析】句意：——你和他關(guān)于那個(gè)問題討論過了嗎？——沒有。當(dāng)我看見他時(shí)，他正在忙碌地準(zhǔn)備歷史項(xiàng)目。When引導(dǎo)的時(shí)間狀語從句，用一般過去時(shí)，主句用過去進(jìn)行時(shí)was/were doing，故選C。
