众所周知，词汇是GRE考试的基础。那么怎样才能掌握GRE必备的词组呢？
这里为大家总结一些常用的核心词组，希望对各位备考有帮助。
本期CRE必备词组:
on the periphery of 在……边缘
释义:
If something is on the periphery of an area, place, or thing, it is on the edge of it.
例句
Geographically, Shanghai is on the periphery of China, while Xi'an is at the heart of the country.
GRE
If individuals on the edge of a group are more vigilant because they are at greater risk of being captured, then individuals on average would have to be more vigilant in smaller groups, because the animals on the periphery of a group form a greater proportion of the whole group as the size of the group diminishes.
如果队伍边缘的个体会因为容易被擒获而保持更高的警惕，那么一般来说队伍规模越小体会们更警惕，因为当整体规模缩小时，处在边缘的个体所占的比例上升了。
