第175句：

High scores on the GRE helped explain who got in; degrees of prestigious universities didn't.

在GRE考试中获得的高分有助于解释谁能人选，而名校的学位则不一定。

六级词汇讲解:

本句由两个分句构成，第一个分句的主干是...scores... helped explain...，其中who got in为宾语从句，充当explain的宾语；第二个分句的主干是degrees...didn’t，省略了谓语help。

get in在句中意为“被录取；进入”。如：

The football player can get in any team.

这名足球运动员有能力在任何球队中立足。

prestigious意为“享有声望的”。如：
