314.An examination of the history of humanity suggested that man in our epoch is so different from man in previous times that it seemed unrealistic to assume that men in every age have had in common something that can be called "human nature. "

對人性歷史的考查表明，我們這個年代的人跟先前年代的人有很大的差別，以至于那種以為所有時代的人都具有被稱做"人性"的共性特征的假設是不切實際的。

六級詞匯講解:

本句的主干是An examination...suggested that...o第一個that所引導的賓語從句that man in our epoch..."human nature."作主句謂語suggested的賓語，該從句中包含一個so…mat…結構，表示某種程度所導致的結果；第三個that引導的賓語從句that men in every age...nature則作assume的賓語；第四個that引導的定語從句that can be called...作定語修飾something。

epoch意為"時期，時代"。如：
The teaching method marked a new epoch in education.

這種教學方法開創了教育的新紀元。

unrealistic意為"不切實際的，不實在的"。如：
He has an unrealistic expectation of winning a prize.

他對獲獎抱有不切實際的希望。

have something in common意為"有共同之處，有共識"。如：
These two articles have something in common．

這兩篇文章有共同之處。"毫無共同之處"則可以表達為have nothing in common。

英語六級考點歸納
以下是so that與so…that…的用法辨析。
so that引導目的狀語從句時，意為"為了，以便"，從句里的謂語動詞前常加上may、might、can、could、will、would等情態動詞。如：
Let's simplify the instructions so that the kids can understand them.
讓我們簡化指令吧，以便于孩子們理解。
The thief hid into the building so that nobody would see him.

那個盜賊躲進樓里，為的是不讓人看見他。

so that還可以引導結果狀語從句，意為"因此，所以"，從句和主句之前常有逗號出現。如：
The boy often tells lies，so that no one believes him.
這個男孩經常撒謊，因此沒有人相信他。
It has been raining for ten days，so that everywhere floods.

雨已經下了10天了，結果到處都洪災泛濫。

so…that…引導的是結果狀語從句，意為"如此……以至于……"，在口語中，that常被省去。如：
Steven was so tired that he fell on sleep in the office.
吏蒂文太累了，以至于在辦公室睡著了。
You spoke so rapidly( that) we could hardly follow you.
你說得太快，我們很難聽清楚你在說什么。
