首先要掌握一些体现原因的词，如because, as, due to, on account of, in that, so... That, such... That, now that, thanks to, owing to, result in, give rise to 等等。熟悉这些词或词组的表达法很重要。
M: I was very sorry to hear about Bill's being fired. I know he was sick a lot and that he usually got to work late.
W: Oh, it wasn't that. Bill made a big error in ac-counting. Even though it wasn't really his fault, his boss was very angry.
Q: Why did Bill lose his job?
A) He hates it.
B) He likes it better than the blue dress.
C) He doesn't know which dress she means.
D) He doesn't like it as well as the blue one.
Bill被解雇的原因是made a big error in accounting.通常现在分词表原因居多，过去分词表结果或趋势，当然少数的例外也是有的。有时，这种因果逻辑型考题的正确答案是经过对有关信息的变换，或是一种解释性语言，这样考生不要指望答案会跟听到的词句完全相同而直接挑选出它。这样的考题是不会出现的。
