参考答案和解析
正确答案： One minute.
解析：
由于车头进隧道到车尾出隧道这一段时间也要包括在内，因此火车通过的路程实际上是隧道长加车长，即0.5+0.25=0.75(miles)。则可列方程80miles/60minutes=0.75miles/x, x=0.5625(minute)≈1minute.

    C) the rapid speed through the air does damage to people's lungs

    D) to those with high blood - pressure, the rapid speed of the train causes them to die


    正确答案：D
    答案：D
    [试题分析]细节题。
    [详细解答]从第二段的内容我们可以找到选项A，B，C对应的内容，而D不对，因为，文中只是提到“In those with high blood-pressure，the movement of the train might produce apoplexy，”，而不是让血压高的人死去。因此，答案为D。

  • 第3题：

    All the flights ______ because of the snowstorm, we had to take the train instead.

    A.were canceleD
    B.had been canceleD
    C.having canceleD
    D.having been canceleD.

    答案：D
    解析：
    本题考查非谓语

    句意：所有的航班因为暴风雪已经取消了,我们决定乘坐火车

    独立主格结构在句中一般只做状语,且用逗号和句子其他成分隔开，且前后主语不一致，逗号前后两个成分,后部分句首并没有并列连词and/so等,前部分也没有because等,说明这是一个简单句,而逗号前面只是一个状语,而不是一个并列句/复合句。如果是并列句,则句子应该写成：All flights had been canceled because of the snowstorm,so we decided to take the train.如果是复合句,则句子应该写成：Because all flights had been canceled because of the snowstorm,we decided to take the train.由此可以排除使用两句的选项AB,

    因为它们都是一个句子的谓语结构；而all flights和cancel之间明显是被动关系,而C则也是句子的谓语结构,则它表明all flights和cancel之间为主动关系,排除.

    D项是语法上的独立主格结构,该结构中的非谓语结构having been canceled的逻辑主语是其前的all flights,并非句子的主语we；它表明all flights和cancel之间为被动关系,且cancel该动作发生在谓语动词decided to...之前.

    故正确答案为D选项。
