4 短语中蕴含的因果关系
对话中往往包含着日常交流中一些常用的短语和习语，对这些短语和习语的识别以及对其意义的正确理解对于因果关系的判断往往也起着非常重要的作用，尤其是在因果关系没有明示的情况下。
Example
You will hear：
Woman：Do you know that Mark turned down that job offered by a travel agency？
Man：Yeah.The hours were convenient，but he wouldn’t have been able to make ends meet.
Question：Why does Mark refuse to take the job？(https://www.daowen.com)
You will read：
A.Because the working hours were not suitable.
B.Because the job was not well paid.
C.Because he had to do a lot of traveling.
D.Because the job was quite difficult.
make ends meet 意为“收支相抵”，由此可以看出，马克嫌这份工作的薪水太低，所以拒绝了。所以正确答案应为B项。
