选择题
The reason ____ their failure you know is _____ they didn’t get fully prepared for the experiment.
A.why; that
B.that; why
C.for; that
D.why; because
答案
答案:C
题目分析:考查介词及表语从句。“the reason for… is that…”是一个固定搭配。意为:...的原因是什么,for修饰the reason,that引导的表语从句,句意:他们失败的原因是他们没有充分准备好实验。因为the reason后面不是定语从句,不能用why。选C。
点评:这里的介词和表语从句,都取决于reason的搭配,reason和for搭配,意思是:…的原因,而cause也是原因,但是和of搭配,还有考生会用because引导表语从句,实际是受到汉语的影响。
