Now that的用法
我们在用now that这一词组时常常出错。它是个从属连词,可以归入because,as,since这一家族,意思和since(既然,由于)接近,但now that必须引出一个新的情况,否则需要由别的词替代。请看下面的例子:
① Now that none of us knows her telephone number, we will have to send someone to deliver the message.
既然咱们谁也不知道她的电话号码,只有找个人去把消息告诉她了。
② Now that he hasn't fully recovered yet,it will not be proper to assign him such a hard job.
既然他身体还没有完全恢复,指派他干这样的难活不适宜。
这两句中用now that不妥,该换成since或as,因为“没人知道她的电话号码”这一事实,过去如此,现在也如此,不是一个新的情况;“他还没完全恢复健康”也不是一个现在才发生的新情况。下面句子的now that都用对了:
① Now that everyone is here let's start work.现在人都齐了,咱们开始干吧。
②Now that We have coverd the whole chapter we may have a discussion next time we meet.
整个一章都看完了,下次见面时就可以是讨论了。“人到齐了”和“整个一章都看完了”都是现在的新情况。
