题目内容
1.Mr Black_______ Shanghai this afternoon.Do you know when the earliest plane to Shanghai _______?( )| A. | is leaving for;takes off | B. | will leave; takes off | ||
| C. | is leaving for; is taking off | D. | will leave; is taking off |
分析 布莱克先生今天下午准备前往上海,你知道去上海的最早的飞机什么时候起飞吗?
解答 答案:A.
根据this afternoon可知,此句表示将来发生的事情,第一空用用现在进行表将来,排除BD;又因为Do you know when the earliest plane to Shanghai,when引导的是宾语从句,表示"什么时候".当主句是一般现在时态,宾语从句应该根据需要选用任何时态,因为"最早的航班是固定的时间",所以用一般现在时态,第二个空用一般现在时态,排除C,故选A.
点评 when引导的宾语从句,当主句是一般现在时态或含情态动词的句子,宾语从句应该根据需要选用任何时态.
