15.Three minutes earlier, they could have escaped such a disaster.( )A. | so | B. | but | C. | or | D. | and |
分析 早3分钟,他们就能逃过这样一场灾难了.
解答 答案:D
A.so 表示因果关系:所以,因此; B.but 表示转折关系:但是; C.or表示选择关系:或者; D.and除了表示并列关系外,还可以用来连接表示目的(and之后)和条件(and之前)等关系的句子;分析句意可知,Three minutes earlier在意思上相当于if引导的条件状语从句"If they leave three minutes earlier";表示如果做到了前半句提到的事情,就会有后面句子表示的结果;故此处用来连接的是表示条件关系的句子;故选D.
点评 做本题时,首先需要掌握各连词的意义及用法,其次根据句意进行逻辑推理,然后选出符合句意的选项.
