        1. 【題目】Our flight ______ at 8:00 pm, so we have enough time to go to the airport.

          A. has taken off B. takes off

          C. took off D. had taken off

          【答案】B

          【解析】

          考查時(shí)態(tài)。句意:我們的航班晚上8點(diǎn)起飛,所以我們有足夠的時(shí)間去機(jī)場(chǎng)。眾所周知,飛機(jī)航班的時(shí)間通常應(yīng)該是固定的,所以句子要用一般現(xiàn)在時(shí)態(tài),故選B。
