20、wherever)连词的辩析8 1).because, as, since, for 的用法： because(因为)，表示原因的语气最强，常用于必然的因果关系，从句一般放在主句后面；另外，回答 why 的问句只能用 because, as(因为)表示一般的因果关系，语气比 because 弱，说明比较明显的原因，它引导的从句可以放在句首也可以放在句尾。since(既然)表示对方已经知道，无需加以说明的原因或事实。for(因为)是并列连词，语气较弱，用来补充说明理由或提供一种解释。如He is not at school today because he is seriously ill. 他

22、hough“尽管，虽然”仅作连词，比较正式，一般可以换为 thoug; though”虽然，尽管，即使”，还可以与 even 连用(evenif),表示“即使，纵然”，作副词时意思是“然而，不过”，不能放在句首，如：He passed the exams although illness prevented him from9 going to classes. 尽管疾病使他无法上课，但是他还是通过了考试。She wont leave the TV set even though her husband iswaiting for her for the supper. 她不愿意离开电视机虽然

23、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。【热点题型】例 1 用 be 动词的适当形式填空。Whose socks _ they?【答案】are【解析】socks 常用于复数，所以动词也要用复数 are.例 2 用适当的助动词填空。-What _ she _ at the weekends?-She usually plays games with her friends.【答案】doesdo【解析】此句是一般现在时态，主语是第三人称单数，所以疑问句要借助于助动词 does,

24、后面的动词用原形，What does she do at theweekends?周末她做什么？例 3 选择正确答案。How many books_ you see on the desk?A. may B. can C. should【答案】B10 【解析】此句意是：在桌子上你能看到几本书？can 能。例 4 用所给代词的适当形式填空。I _ to school from Monday to Friday.
