题目内容
15.-We will carry out the survey as we planned it rains tomorrow.-You needn't worry about the weather.It's sunny tomorrow.( )
| A. | until | B. | unless | C. | if | D. | when |
分析 -我们将按计划进行调查,除非明天下雨.
-你不必担心天气,明天晴天.
解答 答案:B;until直到;unless除非;if,如果;when当…时候;根据句意We will carry out the survey as we planned 我们将按计划进行调查,it rains tomorrow明天下雨.可知二者是条件关系,而且"明天下雨"和"我们将按计划进行调查"在逻辑上是相矛盾的,故此处用表示否定的连词,表示一种否定意义的假设,因此用unless"除非,要不然",相当于if…not;故选B.
点评 根据句中信息推测出该句的句意是解答此题的关键;还要对给出的答案进行分析和比较,从而作出正确解答.
