答案解析:
1.【答案】B。解析:考查主语从句。句意:在这个商店里你用现金支付还是信用卡支付都没有关系。It为形式主语,whether引导的从句为真正的主语,whether…or…“是……还是……, 不管……还是……”,故选B。
2.【答案】D。解析:考查部分倒装。句意:直到我填完这张表,我才意识到有一半的问题与我无关。not until放在句首时句子使用部分倒装,即将情/be/助提前。根据上下文可知,时态为一般过去时,因此把did提前,故选D。
3.【答案】B。解析:考查虚拟语气。句意:如果他上周五已经离开了的话,他就已经到巴黎了。根据句意以及句中的would have got可知本题考查虚拟语气。虚拟语气用于表示过去情况的条件句中,主句用would have+过去分词,从句由had+过去分词构成,省略if后,助动词had可以提到句首,这时从句要部分倒装。此句原形为If he had left last Friday, he would have got to Paris,倒装后if可以省略,助动词提前,故答案选B。
4.【答案】译文:污染是我们现在必须解决的一个迫切问题。解析:略
