最近在梳理这些真题的过程中，发现了一些很熟悉的题，再仔细对照，发现是去年ETS发布的第三套官方模考题（PPO3）的题目。

而这些题，你猜猜，都是哪一年的考题？

答案是：2012-2013年

比如下面这道巨难无比的逻辑题，最早出现在2013年2月12日：

In Bronze Age farm fields near the ancient circle of stones at Stonehenge, the furrows were found plowed at right angles to an imaginary line to the place where the Sun rises on the shortest day of the year. Some of the major stones at Stonehenge are also aligned, apparently intentionally, with that point on the horizon. Since these fields date from shortly after Stonehenge was completed, the plowing was probably consciously guided according to systematic observation of the Sun' s position.

Which of the following, if true, most strengthens the argument?

A. The landscape in which these fields were situated made it more difficult to plow in the direction in which the furrows were plowed than in other directions.

B. The direction of the plowing on any other Bronze Age farm fields near Stonehenge cannot be determined because of the deep plowing that has taken place in modern times.

C. Bronze Age farmers had primitive plows that were not capable of turning over soils heavier than those in the fields near Stonehenge.

D. The Bronze Age farm fields near Stonehenge were laid out in clusters that were not immediately next to other such clusters.

E. Even before Stonehenge was built, farmers in the area could have made a practice of observing the Sun' s position at various times of year.

再例如PPO3 Easy模式中的这篇短阅读，则最早出现在2012年3月31日：

There are two competing hypotheses regarding the origin of gold found in South Africa' s Witwatersrand basin. The placer model maintains that rivers transported sediments that included grains of gold into the basin; these sediments eventually transformed into rock. The hydrothermal model postulates that gold-rich hot fluids traveled upward through fractures within Earth' s crust, adding gold to the basin after the sediments had become rock. The question could be settled by establishing the age of the gold grains. If they are older than their host rock, they must have come from a source predating the sedimentation—namely, older terrain eroded by the river waters. If they are younger, they must have arrived after the sediments were deposited.

PPO3发布于2019年，用到的多是2013年的题，而这些题发布出来，以后肯定就不会再被考到了。

这说明GRE真题的生命周期约为6年。

当然，这不是说6年前的题绝对不会再被考到，但是我近期考试的经验来看，GRE的题库更新速度其实还是很快的，六年前被考过的题虽然今年依然会考，但是所占比例已经很低。大量的题目其实是今年才第一次出现而在年内被反复考到（ ETS题库告急？真题出现“内循环”！ ）。

所以总结来说，老题依然会被考到，但是越新的题“命中”率就会越高。
