分析 如果不小心应对处理,小帆船很容易翻在水里.
解答 答案A.
本题考查省略句.在whether,if,unless 等引导的条件状语从句中,当状语从句的主语与主句的主语一致时,并且从句中含有系动词be,可以省略状语从句的主语和系动词be.句子的完整形式是"if/unless it is not managed carefully",省略后的形式是"if/unless not managed carefully",根据省略的原则可排除B和D.if"如果",引导条件状语从句.unless"除非,如果不",在意义上相当于if…not,因此在有些场合中unless与if…not可互换使用,引导条件状语从句.根据句子所表达的意思可排除C,如果选C句子应改为"unless managed carefully".故答案选A.
点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.
