2018考研英語長難句分析指導（十二）

　　We assumed that there were forces of attraction between molecules which varied rapidly with the distance so that the attraction between molecules that were more than a few ten millionths of a millimeter apart was very small but became considerable when the molecules approached more closely.

　　結(jié)構(gòu)分析:句子的框架是We assumed that there were forces of attraction…。that引導賓語從句。此賓語從句中套嵌一個由which引導的定語從句修飾先行詞forces of attraction; so that the attraction between molecules…是so that結(jié)構(gòu)引導的結(jié)果狀語從句;在此狀語從句中，除主干結(jié)構(gòu)the attraction…was very small but became considerable…，又有that were more than a few ten-millionths of a millimeter apart做定語從句修飾先行詞molecules和when the molecules approached more closely做狀語從句，修飾…but became considerable。considerable譯為“相當大(或多的)”。

　　譯文：我們曾經(jīng)假定，分子之間存在著引力，這種引力隨著分子之間距離的不同而有顯著的變化，因而，在間距為千萬分之幾毫米的分子之間的引力是很小的，但是分子靠得很近時，這種引力會變得相當大。
