恭喜恭喜啊，我是佛哥，没有抢到沙发真可惜，呵呵，我们群的实力真是很强悍啊。希望后面考试的兄弟姐妹继续创造辉煌。

In 1975 Chinese survey teams remeasured Mount Everest, the highest of the Himalayan mountains. Like the British in 1852, they used the age-old technique of “carrying in” sea level: surveyors marched inland from the coast for thousands of miles, stopping at increments of as little as a few feet to measure their elevation, and marking each increment with two poles. To measure the difference in elevation between poles, surveyors used an optical level—a telescope on a level base—placed halfway between the poles. They sighted each pole, reading off measurements that were then used to calculate the change in elevation over each increment. In sight of the peaks the used theodolites telescopes for measuring vertical and horizontal angles—to determine the elevation of the summit.
这是第一段

AppleStrudel

第二段应该是一样的。我不记得考试时候说了三个还是四个纠正，但是基本是原文。
第一段就不一样。我很肯定考试文章里没有谈两根杆子，通篇没有杆子。但是第一段具体讲什么，我一点也想不起来了。
这篇很简单，近乎白话文，题目选项也很简单。

很久很久以前，在遥远的东方，亚洲大陆上的最大的文明古国---中国，流传着这样一个传说，如果一个孩子与白鹭同名，那么在她成年之后，必然直冲云霄，翱翔天际，环游四海，让世人所仰视。于是，有越来越多的父母坚信这个美丽的传说，把最美好的期盼寄托在了子女身上。
今日，美丽与智慧化身，集结了东方美女的气质与西方美女的智慧融为一身的楼主，用实际行动向世人证明了这个美丽的传说的有一次成为了现实。是的，她做到了，She dreams it.So she can do it.
此时此刻，所有有幸见到这篇帖子的人，都有资格说，是的，我见证。见证了中国未来的领袖们在帮助祖国繁荣昌盛的道路上一地前进着。他们沉着，冷静，机智，不屈不挠的精神让世界为之感动~
有他们在，中国未来更美好~有他们在，世界的未来会更光明~
