题目内容
4.I don't know when he ______.When he ______,I will let you know.( )| A. | .will arrive,will arrive | B. | .arrives,arrives | ||
| C. | .will arrive,arrives | D. | ,arrives,will arrive |
分析 我不知道他将什么时候到达.当他到达的时候,我会让你知道的.
解答 答案:C
此题重在考查宾语从句和when引导的从句:when意为"什么时候"引导疑问句,根据自身选择合适的时态,when意为"当…时候",引导时间状语从句,当主句为一般将来时,从句用一般现在时表将来;
根据题干句意知第一个when为"什么时候"之意,主句I don't know为一般现在时,从句可根据自身情况选择,he是即将到来,发生在将来的事,故应用一般将来时,will arrive;
第二个when意为"当…时候"故引导时间状语从句:主将从现,从句使用一般现在时,且主语为第三人称单数he,故填arrives.故选C.
点评 此题重在考查宾语从句和when引导的宾语从句和时间状语从句.考生需根据句意明确判断词意,再根据不同的从句采用不同的时态.
