[tr][/tr][td=1007][/td]中国人测量珠峰的那道,似乎9月jj上有了..一道问下面哪个会增加R问题: 增加和山峰的距离..一道主题题,其它忘了…
[tr][/tr][td=1007][/td]中国登山队测量喜马拉雅山高度的那道jj。以前的G友说过这篇文章第一段可以跳过,同意他的看法,只要大致扫过第二段所提到中国登山队不同于英国队的几点作法,心中有个谱即可作答。说真的,我只看懂其中第一点:光线穿透云层时会产生折射(refraction),其它两点似懂非懂,并不影响答题。大家不需浪费太多时间钻研里面的生词或概念,题目都很浅显、简单。 问题: (1) 主题题。参考答案:描述对某项程序(procedure)持续的改进。 (2) 下列哪些情形有可能产生折射。参考答案:当光线穿透湿气很重的云层时。 (3) 下列那个选项不是文中所提到改进的作法。参考答案:使用工具的改良。 (4) 目的题:第二段第一句话的作用。第一段在讲英国队和中国队一致的一些作法,第二段才开始讲述中国队的改良作法,有明显的转折 (Chinese team, however, blablabla…)。参考答案:translates the focus
[tr][/tr][td=1007][/td]有中国队北极科考的一篇。第一段都不需要看。第二段开始讲述了三个source of error,第一个是折射, 第二个不记得了, 第三个是uneven海平面
[tr][/tr][td=1007][/td]中国登山队对喜马拉雅山最高峰进行测试,用的方法基本和british队的一样,但是中国队才用了一些其他方法来纠正或者避免以前british队测量的error ” 第 一段没什么重要,主要是第二段,但是专业术语很多,建议速读,再回去定位就好。有一题问第二段开头一句话的作用。还有一题问一下那个选项不是影响测量的准 确性的要素。因为时间来不及仔细看了,在两个选乡间犹豫了一下,一个是mirage,一个是inaccurate instrument.

原文: 71. GWD-26-Q32-Q35 中国人改进了英国人测量珠峰高度的方法 In 1975 Chinese survey teams 1975年中国人量度珠峰,使用的 remeasured Mount Everest, the highest 技术和1852年英国人的相同。 of the Himalayan mountains. Like the 他们从海岸线开始行进,每隔几 Line British in 1852, they used the age-old 步量度一次上升高度。 (5) 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 mark- (10) ing each increment with two poles. To measure the difference in elevation 使用工具:置于两根杆中间的望 between poles, surveyors used an 远镜。 optical level—a telescope on a level base—placed halfway between the (15) poles. They sighted each pole, read- ing off measurements that were then used to calculate the change in eleva- tion over each increment. In sight of 看到峰顶时,他们使用经纬仪 the peaks they used theodolites— 探定顶点的上升。 (20) telescopes for measuring vertical and horizontal angles—to determine the elevation of the summit. The Chinese, however, made 但中国人努力改正英国人的误 efforts to correct for the errors that 差。 (25) had plagued the British. One source 误差1:由于不同温度压力造成 of error is refraction, the bending of 的光折射。这会产生峰顶幻象。 light beams as they pass through air layers of different temperature and pressure. Because light traveling. (30) down from a summit passes through many such layers, a surveyor could sight a mirage rather than the peak itself. To reduce refraction errors, the 解决:1,减少通过经纬仪的光, Chinese team carried in sea level to 2,使用天气气球测量温度压力。 (35) within five to twelve miles of Everest’s summit, decreasing the amount of air that light passed through on its way to their theodolites. The Chinese also launched weather balloons near their (40) theodolites to measure atmospheric temperature and pressure changes to better estimate refraction errors. Another hurdle is the peak’s shape. 误差2:测量者们的测量点不同。 When surveyors sight the summit. (45) there is a risk they might not all measure the same point. In 1975 the Chinese installed the first survey 解决:安装一个红色灯塔。 beacon on Everest, a red reflector visible through a theodolite for ten (50) miles, as a reference point. One 误差3:海平面不平。 more source of error is the uneven- ness of sea level. The British assumed that carrying in sea level would extend an imaginary line from (55) the shore along Earth’s curve to a point beneath the Himalaya. In reality, sea level varies according to the irregular interior of the planet. The Chinese used a gravity meter to 解决:用重力计改正误差。 correct for local deviations in sea level. ------------------------------------------------------------- Q32 It can be inferred from the passage that refraction would be most likely to cause errors in measurements of a mountain’s elevation under which of the following conditions? A. When there are local variations in sea level B. When light passes through humid air C. When theodolites are used relatively far from the mountain peak. D. When weather balloons indicate low air temperature and pressure. E. When sea level has been carried in to Within five to twelve miles of the summit.
------------------------------------------------------------- Q33 Which of the following best describes the purpose of the sentence in lines 23-25 (“The Chinese…the British”)? A. Introduce a definition B. Signal a transition in focus C. Summarize the preceding paragraph D. Draw a contrast between two different theories. E. Present information that contradicts the Preceding paragraph.
---------------------------------------------------- Q34 Which of the following is NOT mentioned as a possible source of error in surveying mountain elevation? A. Mirages B. Refraction C. Inaccurate instruments D. Variations in sea level E. Uncertainty about the exact point to be Measured
--------------------------------------------------- Q35 The primary purpose of the passage is to A. provide details about improvements to a process B. challenge the assumptions underlying a new method C. criticize the way in which a failed project was carried out D. call for new methods to solve an existing problem E. explain the theory behind a new technique
狗主的 原话“第一题和最后一题不一样。第一题也是推论,但是推论的中英两次测量活动异同点。最后一个失忆了…… ” |
