If the weather is fine，we will go. If __________，__________. A. not，not B. no，no C. not，no D. no，not http://yingyu.chazidian.com 此题应选A。这是一个省略句，若补充完整应该是： If the weather is fine，we will go. If the weather is NOT fine，we will NOT go. 如果天气好，我们就去，若天气不好，我们就不去。 该句的特点是：后句与前句的用词和句式完全相同，只是前句为肯定，后句为否定，为了简洁起见，将后句与前句相同部分省略，只保留否定词 not。类似的例子(只保留否定词not)如： 1. —Can you repair it yourself? 你自己会修吗? —I am afraid not. 恐怕不行。 (=I am afraid I can’t repair it myself. ) 2. —Did you know anything about it? 这事你以前知道吗? —Not until you told me. 你告诉我才知道。 (=I didn’t know anything about it until youtold me. ) 3. —Will it rain today? 今天会下雨吗? —I hope not. 希望不会。 (=I hope it will not rain today. )
