考题讲解

题目分析:
本题有些选项比较相对有难度,大家需要注意。

选项分析:

A选项:比较对象有误。最后的 they had anticipated是过去完成时。过去完成时必须要有一个过去时间作为参照,通常表示事件在这个过去时间点之前发生。显然地,在本选项中,由于cause是一般现在时,所以anticipate这个过去完成时没有时间的参照。

B选项:Correct. 本选项在语法和逻辑上均是正确的。

C选项:细分语法成分可知,划线部分是一个主系表结构。主干信息为:accidents, weather condition, and errors is the cause. 如果只看划线部分,这个主系表结构也是可以接受的。但是,由于未划线部分必须和划线部分保持but的关系,所以我们还要保证本选项能和未划线部分之间形成转折关系。未划线部分讲的是:喷洒农药是被小心的计划的。要和划线部分转折,我们必须要说,某事会引起计划之外的事情,而不能说,某事是一个原因。例如:
正确:虽然事故是不幸的,但是它引起了我们的警示。
错误:虽然事故是不幸的,但是它是警示的原因。
另外, they had anticipated错误同选项(A)。

D选项:
定语从句that are not foreseeable需改为 that cannot be foreseen。细分成分可知,本选项是主系表结构,即,
weather conditions are not foreseeable.
这句话讲的是:天气情况是不可以预测的。它并不代表这个天气状况没有被预测出来。例如:
(1) The book is not touchable.
(2) The book is not touched
句(1)讲的是“书是不可触摸的”,这是在描述书的一种特征,即,可能这些书是电子书,总之它们是不具备可触摸性的。句(2)讲的是“书没有被触摸过”。即,这些都是真的书,只不过没被触摸过。
同理,本题讲的是“没有被预见到的天气条件”,而不是“那些不具备可预见性的天气”(可能是一些神奇的气象条件,类似于刚才例子里的电子书),因此本选项是不正确的。

E选项:本选项错误同选项(A)。
