正确的雅思阅读做题步骤
有很多同学在做雅思阅读的时候是按照题目的顺序来做，这样往往会导致在较难的题目上花费时间太多而简单的题目没有时间做，今天小编给大家带来了告诉你最最正确的雅思阅读做题步骤,希望能够帮助到大家，下面小编就和大家分享，来欣赏一下吧。
告诉你最最正确的雅思阅读做题步骤
首先，要选择正确的阅读方法。
雅思阅读量非常大，一般的中国考生根本无法把文章全部读完，“跳读”和“略读”就成了考试时无法取代的阅读方法。这样能够节省很多做题时间，如果像练习时的精读一样，根本不可能完成整个雅思阅读考试。那么选择跳读和略读就要注意一些阅读的细节：
1.先读题目，在做题，如果题目过度可以先读前几题，然后带着问题进行阅读，这样更加的有目的性，遇到重点信息也不至于漏掉，以至于反复回文定位。
2.仔细解剖文章首尾段或者各个段落的首句，理解大意。这样会对文章内容有个大致的了解，如这篇文章讲的是生物化学，环境保护还是宇宙探索。搞清楚文章的主题和作者想表达的内容。
3.标记定位词。所谓定位词，其核心即是一个可以根据题干回原文定位，并且能够找到出处的词，以帮助快速锁定答案解题。也就是我们所说的关键词。这也是节省阅读时间的一大特点。
然后，仔细阅读题干，开始作答。
上述内容基本完成了对文章的理解和重要信息的定位。那么接下来自然就是开始答题的步骤。此时需要做的就是仔细阅读题干，然后将问题(或选项)定位到文章中具体的某个段落甚至具体的句子。
1. 根据题型特点。可以选择简单，已经基本能够确定答案的题目，或者自己比较擅长的题型先作答。对于比较难的可以放在后面做仔细分析，以免导致简单题失分。
2. 按题目顺序做题。雅思阅读的出题规律很特别，有助于帮助大家做题，即一般情况下都是按照文章的段落和内容顺序进行题目的设置，所以第二题的答案一般在第一题答案内容之后。
3. 根据自己对文章的理解进行答题。如果时间充足的话可以看完题后先不看选项，根据自己对文章的了解找到答案，然后再跟选项做比较，找出正确答案。
雅思阅读机经真题解析-探测陨石湖
Detection of a meteorite Lake
A
As the sun rose over picturesque Lake Bosumtwi, a team of Syracuse University prepared for another day of using state-of-the-art equipment to help unlock the mysteries hidden below the lake bottom. Nestled in the heart of Ghana, the lake holds an untapped reservoir of information that could help scientists predict future climate changes by looking at evidence from the past. This information will also improve the scientist’s understanding of the changes that occur in a region stuck by a massive meteorite.
B
The project, led by earth sciences professor Christopher Scholz of the College of Arts and Sciences and funded by the National Science Foundation (NSF), is the first large-scale effort to study Lake Bosumtwi, Earth’s surface. The resulting crater is one of the largest an most well-preserved geologically young craters in the world, says Scholz, who is collaborating on the project with researchers from the University of South Carolina, the University of Rhode Island, and several Ghanaian institutions. “Our data should provide information about what happens when an impact hits hard, pre-Cambrian, crystalline rocks that are a billion years old”, he says.
C
Equally important is the fact that the lake, which is about 8 kilometers in diameter, has no natural outlet. The rim of the crater rises about 240 meters above the water’s surface. Streams flow into the lake, Scholz says, but the water leaves only by evaporation, or by seeping through the lake sediments. For the past million years, the lake has acted as a tropical rain gauge, filling and drying with changes in precipitation and the tropical climate. The record of those changes is hidden in sediment below the lake bottom. “The lake is one of the best sites in the world for the study of tropical climate change,”Scholz says. “The tropics are the heart engine for the Earth’s climate. To understand global climate, we need to have records of climate changes from many sites around the world, including the tropics.”
D
Before the researchers could explore the lake’s surface, they need a boat with a large, working deck area that could carry eight tons of scientific equipment. The boat-dubbed R/V Kilindi-was built in Florida last year. It was constructed in modules that were dismantled, packed inside a shipping container, and reassembled over a 10-day period in late November and early December 1999 in the rural village of Abono, Ghana. The research team then spent the next two weeks testing the boat and equipment before returning to the United States for the holidays.
E
In mid-January, five members of the team-Keely Brooks, an earth sciences graduate student; Peter Cattaneo, a research analyst; and Kiram Lezzar, a postdoctoral scholar, all from SU; James McGill, a geophysical filed engineer; and Nick Peters, a Ph.D. Student in geophysics from the University of Miami-returned to Abono to begin collecting data about the lake’s subsurface using a technique called seismic reflection profiling. In this process, a high-pressure air gun is used to create small, pneumatic explosions in the water. The sound energy penetrates about 1,000 to 2,000 meters into the lake’s subsurface before bouncing back to the surface of the water.
F
The reflected sound energy is detected by underwater microphones-called hydrophones-embedded in a 50-meter long cable that is towed behind the boat as it crosses the lake in a carefully designed grid pattern. On-board computers record the signals, and the resulting data are then processed and analyzed in the laboratory.” The results will give us a good idea of the shape of the basin, how thick the layer of sediment are, and when and where there were major changes in sediment accumulation,” Scholz says, “we are now developing three-dimensional perspective of the lake’s subsurface and the layers of sediment that have been laid down.”
G
Team members spent about four weeks in Ghana collecting the data. They worked seven days a week, arriving at the lake just after sunrise. On a good day, when everything went as planned, the team could collect data and be back at the dock by early afternoon. Except for a new relatively minor adjustments, the equipment and the boat worked well. Problems that arose were primarily non-scientific-tree stumps, fishing nets, cultural barriers, and occasional misunderstandings with local villagers.
H
Lake Bosumtwi, the largest natural freshwater lake in the country, is scared to the Ashanti people, who believe their souls come to the lake to bid farewell to their god. The lake is also the primary source of fish for the 26 surrounding villages. Conventional canoes and boats are forbidden. Fishermen travel on the lake by floating on traditional planks they propel with small paddles. Before the research project could begin, Scholz and his Ghanaian counterparts had to secure special permission form tribal chiefs to put the R/V Kilindi on the lake.
I
When the team began gathering data, rumors flew around the lake as to why the researchers were there. “Some thought we were dredging the lake for gold, others thought we were going to drain lake or that we had bought the lake,” Cattaneo says, “But once the local people understood why we were there, they were very helpful.”
Question 14-18
Do the following statements agree with the information given in Reading Passage 1? In boxes 14-18 on your answer sheet, write
TURE if the statement is true
FALSE if the statement is false
NOT GIVEN if the information is not given in the passage
14. With the investigation of the lake, scientist may predict the climate changes in the future.
15. The crater resulted from a meteorite impact is the largest and most preserved one in the world.
16. The water stored in Lake Bosumtwi was gone only by seeping through the lake sediments.
17. Historical climate changes can be detected by the analysis of the sediment in the lake.
18. The greatest obstacle to research of scientists had been the interference by the locals due to their indigenous believes.
Question 19-22
There are three steps of collecting data from the lake as followings, please filling in the blanks in the Flow Chart below:
Summary

参考译文：
A:当太阳从如花的博苏穆图湖面上升起，Syracuse 大学的研究学者们正准备在新的一天用最尖端的设备来解开深藏在湖底的谜团。博苏穆图湖坐落在加纳的中心位置，蕴含着很多未知的讯息，通过对该湖过往的观察可以帮助科学家预测未来的气候变化，以及对被巨大陨石撞击过的地区的变化。
B: College of Arts and Sciences 地球科学系的教授Christopher Scholz 负责这个勘察项目，该项目是由National Science Foundation(NSF)提供资金支持的，也是第一个大规模研究这个110万年前由巨大的流星撞击地球表面形成的湖的项目。据Scholz称，这次撞击形成的火山口是世界上最大也是保存最完整的年轻的火山，Scholz正和来自亚利桑那大学，南加利福尼亚大学，罗德岛大学以及几家加纳的研究机构的学者一起探索博苏穆图湖之谜，他们致力于弄明白在前寒武纪当流星猛烈撞击地球表面那些10亿年前形成的结晶岩时发生了什么。
C: 另一个同样重要的事实是这个直径达8公里的湖没有天然的出口，火山口的边缘高出湖面大约250米。Scholz发现，溪流汇入湖中，但是水通过蒸发和从湖内沉淀中渗透而流失。在过去的几百万年中，博苏穆图湖作为热带雨量的测量器，湖水量的变化和降雨量以及热带气候密切相关。这些变化的记录藏在湖底的沉淀物中，Scholz认为博苏穆图湖是世界上最适合研究热带气候变化的地方，而热带是地球气候的加热器。为了更好地研究全球气候，人们需要收集全世界很多不同地方的气候变化的记录，包括热带。
D: 在研究者探索湖的表层时，他们需要一艘船，船上需要有足够的工作空间来装载8吨重的科学设备。去年，他们在佛罗里达州建造了一艘名为R/V KIlindi的船，它是在1999年11月末12月初废弃的集装箱内用了10天的时间在加纳的Abono郊区重新组装完成的。研究小组在接下来的两周时间测试了这艘船及上面的设备，这些完成之后他们才返回美国休假。
E: 在1月中旬，小组的5个成员——来自SU的三位成员地球科学研究生Keely Brooks，研究分析员Peter Cattaneo，博士后学者Kiram Lezzar以及地质物理学工程师James McGill和来自迈阿密大学的地质物理学工程师Nick Peter 博士回到Abono开始通过地震反射成像收集湖面表层的数据。在这个过程中，他们用一个高压气枪在水里引发小型爆破。声音产生的能量在反射回来之前会穿过湖面下大约1000到2000米。
F: 反射回来的声音通过水下镶嵌在50米长的电线中的麦克风探测，电线吊在船的后面，当船穿过湖面的时候，通过精心设计的固定模式收集信号。船上的电脑记录收集到的几号，然后信号被带到实验室进行处理和分析。Scholz说道，“研究结果可以帮助我们更好地研究盆地的形状，湖底沉积物的厚度，以及在沉积物积累的过程中这些主要的变化时在什么时候以及在什么地方发生的，我们正在建立三维的湖面 结构以及沉积层的结构。”
G: 小组成员在加纳花了约4周的时间收集数据，一周工作七天，太阳刚升起来他们就已经到达湖边开始工作。在天气晴朗的时候，所有的事情都能按计划顺利进行完，他们在下午把收集到的数据带回到码头。除了几次相关的微小的调整外，船和其上的设备运作良好。问题主要存在于非科技方面，比方说树桩，渔网，文化障碍以及他们和当地村民偶尔的误解。
H: 博苏穆图湖是国内最大的天然淡水湖，对Ashanti人来说是很神圣的，因为他们相信，他们的灵魂会到湖里向他们的神明致敬。博苏穆图湖还是周边26个村庄捕鱼的主要场所，与传统的独木舟和小船是禁止在湖面上航行的。渔民通过传统的木板在湖面上来往，使用小型的船桨。在研究项目开始前，Scholz和加纳的同伴要从部落的首领那里获得特批才能把R/VKilindi船放入湖中。
I: 当小组开始收集数据的时候，关于研究者为什么在湖面上的谣言四起。Cattaneo说：“一开始有的人以为我们再湖里找金子，还有一些人一位我们再疏通湖水，或是我们把这个湖买下来了。但是，当他们了解到我们来的原因时，他们就开始很热心地帮忙。
