328.They will take a call from a persistent parent, even if they're loaded with works.

英语四级译文:
即使(儿女们)工作上忙得不可开交时，他们的父母也会经常打电话来催促。

四级词汇讲解:
even if意为“即使”，引导让步状语从句，相当于even though。二者的区别在于:even if表递进关系，用来强调尽管某事可能存在或发生，另一种情况依然存在;而even though则表转折关系，用于引出事实，使得句子的陈述令人意想不到。如:

※ Even if you saw him pick up the money, you can't be sure he stole it.就算你看见是他拾起的钱，你也不能肯定地说，钱就是他偷的。

※ Even though I hadn't seen my classmate for many years, I recognized him immediately.虽然多年没有见过我的同学，我还是马上认出了他。

英语四级考点归纳:
与even if, even though形式类似的表达还有even so，但是even so为短语，意为“即使这样”，通常用作插入语，而不能引导从句。如:

Professor Lee failed him in the finals;even so，Peter is still happy for the coming holiday.李教授把彼得的期末成绩判为不及格;即使如此，彼得还是为即将到来的假期而感到开心。
