题目内容
10.We'll have a picnic in the park it rains tomorrow.( )| A. | if | B. | unless | C. | when | D. | because |
分析 我们将在公园野餐,除非明天下雨.
解答 答案:B if如果;unless除非;when当…的时候;because因为.结合语境,并根据it rains tomorrow可知这是明天不去野餐的条件,结合前句只有理解为否定的条件前后语义才会连贯,所以这里应是指如果不下雨,就会去野餐,表示一种否定的假设,结合选项,只有unless有这种含义,意为除非,相当于if not,其后引导一个条件状语从句.故选B.
点评 做此题要注意根据句意选择使前后句子语义连贯的连词,尤其是注意像unless这样表达否定意义的连词的用法.
