2020天津公安消防考军校考试-连接词（三）

(4)till/until与not…till/until的区别：前者表示一个延续性的动作,后者表示一个才开始的动作。如：I will stay here and watch the baby until you return.(我会呆在这里看着娃娃直到你回来)(stay这个动作一直进行到你return) / They won’t go on working until they get what they think is reasonable.(他们要到获得了他们认为合理的东西时才会继续干下去的)

另外till与until基本可以互换,但是在句首时只能用until,不能用till. 如：Until the last minute of the match we kept playing.(我们坚持到比赛的最后一分钟)/ Not until he had finished his work did he go home.(直到做完工作他才回家)(倒装句)

(5)though与although的区别：两个词都表示“虽然”,均不可以与but同时使用,但在句中可加still或yet连用。although“尽管、虽然”仅作连词,比较正式,一般可以换为though; though“虽然、尽管、即使”,①还可以与even连用(=even if),表示“即使、纵然”,②作副词时意思是“然而、不过”,不能放在句首。③although不能放在句末，though则可以，用“，”隔开。如：He passed the exams although illness prevented him from going to classes.(尽管疾病使他无法上课但是他还是通过了考试)/ she won’t leave the TV set,even though her husband is waiting for her for the supper.(她不愿离开电视机虽然丈夫在等她吃饭)/ It was a quiet party. I had a good time, though.(这是个不热闹的聚会尽管如此我还是玩得很开心)

(6)prefer to…rather than…与prefer…to…的区别：prefer to…rather than…后面都是用动词原形,prefer…to…都是用动名词或名词。如：I prefer English to Japanese.(与日语相比我更喜欢英语)/ I prefer to learn English rather than learn Japanese. (与日语相比我更喜欢学英语)
