Question

【題目】The plane to Thailand ________ by the time I got to the airport in a hurry.

A. took off B. taken off

C. had taken off D. has taken off

Answer 1

【答案】C

【解析】

句意：當(dāng)我匆忙趕到機(jī)場(chǎng)時(shí)，飛往泰國(guó)的飛機(jī)起飛了。根據(jù)時(shí)間狀語(yǔ)“by the time I got to the airport in a hurry.”可知主句動(dòng)作發(fā)生在前，從句動(dòng)作發(fā)生在后，而從句用的是一般過(guò)去時(shí)，所以主句該用過(guò)去完成時(shí)。其構(gòu)成為had+過(guò)去分詞，因此答案選C。
