中考英语知识点:because、as、since、for的用法 because(因为)表示原因的语气最强, 常表示必然的因果关系,从句一般放在主句后面; 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. As all of you have got here, now, let’s go to the zoo. I will ask Lin Tao to go with me since you are very busy We must be off now for the match starts at 7:00. (责任编辑:admin) |
