1、雅思阅读提速技巧 在练习雅思阅读时，做题速度是很多烤鸭的弱点，一起来看雅思阅读提速的技巧经验吧。下面就和大家分享，来欣赏一下吧。雅思阅读提速技巧 经验分享雅思阅读相对于其他单项来说本应该是同学们的强项，但是如果阅读速度太慢，或者总是纠结在选答案迟迟无法作答，会令同学们马失前蹄。怎么办呢?不急，为你整理了九条雅思阅读的“提速高招”!1.先看题目后阅读考试时，一定是先看阅读题再看原文。注意：(1)阅读试题每一部分的开头与结尾;(2)每部分有多少道题;(3)每部分的答题时间;(4)先回答哪些问题。在开始阅读所给*前，应首先弄清需要回答的问题，再带着这些问题，去读那些与答题有关的部分。这样就可以节省出
2、更多时间，达到事半功倍的效果。2.主旨题+细节题主旨题与细节题考察考生是否具备掌握主旨、查找细节的能力。主旨题：List of Headings细节题：除List of Headings以外的所有题型，包括T/F/NG、Matching、Summary、Multiple Choice等。对于主旨题，我们主要通过把握段落结构(总分、分总、总分总、分总分)，重点抓住该段的主题句和反复出现的词汇(即高频词或核心词)，来进行突破。一般来说，主题句50%以上在段首句。做雅思阅读细节题时一定要先确定关键词然后回原文中定位，找一一对应关系。其中，T/F/NG题考察的是理解原文具体细节的精确度。而Matchi
3、ng题则考察学生查找细节的速度。先做主旨题再做细节题可以使定位细节变得更快更准确。3.合理安排阅读答题时间平时在家备考雅思阅读的时候就要养成比较好的做题习惯，计时并且是细到每篇雅思阅读*计时!第一篇一般8分钟完成，第二篇和第三篇分别是12-15分钟，超过时间发现题目还没有做完就不要再思考了。不要在某道小题目上思考太久，争取把能够做对的题目全都做对。4.注意力训练：20分钟完成一篇*一开始训练雅思阅读，很多考生可能无法适应1小时3篇阅读*的题量?很难注意力集中?这时候可以做拆分练习，20分钟做完一篇雅思阅读*，坚持1个月之后，随着对雅思阅读题型的熟悉，注意力逐渐能够长时间集中之后，很多考生就能适
4、应这种高强度的雅思阅读考试了。5.单项训练：一次做一个题型雅思阅读的题型很多，除了基本的单选和填空题，还包括判断、段落理解题，不同的题型的考察重点不同，比如，List of Headings考察是段落理解能力，True/ False / Not given考察的是句子理解能力。有针对性的答题往往会总结出适合自己的答题规律。6.“换句话说“别看了“换句话说、也就是说”意味着后面的内容与前面一致或是对前面的解释，因此只用看前面的内容即可。常见的表达有：that is (to say)，put another way，in other words等。如：“The state has no oblig
5、ation to provide a health-care system itself, but to ensure that such a system is provided. Put another way, basic health-care is now recognized as a public good, rather than a private good that one is expected to buy for oneself.”(剑桥雅思真题4, Test 4, Reading Passage 3) 略掉“Put another way”后面的内容，只看前面。7.
6、“论据“不看为了论证观点，*中经常会大量出现各式各样的论据，但它们并不是*的重点。故概览*时，论据可以先忽略不看。而常见的“论据”形式有：含“举例”的句子：for example / instance，e.g.，such as等;含“数据”的句子：百分比(%，percentage)，描述统计结果的数字;引用名人/专家言论(直接/间接引语)的句子;以some，a few，others等表达“某些”的单词为开头的句子。8.同义词的替换雅思阅读相比托福阅读，雅思会更加体现词汇量的重要性，特别是在雅思的阅读中，经常会出现同义的互换。所以，在日常生活中，大家应该加强同义互换能力的锻炼。往往正确答案是原文
7、的是这样写的，可是关键考点单词有可能被同义替换掉。如果不懂得同义词的使用的话，你可能会一脸懵。所以在日常生活中，我们应该多去扩展同义词、近义词和反义词等的积累。9.整理阅读词库在平时的阅读过程中，习惯性的去积累整理自己的词库语库，日常可以多去翻看阅读，这比你耗时间去背诵记词来得更快，在阅读的过程中一方面把题目做完了，一方面还能通过语境把词汇背下来，这样背单词记得会更牢。雅思考试阅读模拟试题精选Dont wash those fossils!Standard museum practice can wash away DNA.1.Washing，brushing and varnishing f

33、 systemStaff and agenciesWednesday December 27，20XXGuardian Unlimited1.A European spacecraft took off today to spearhead the search for another “Earth” among the stars.2.The Corot space telescope blasted off aboard a Russian Soyuz rocket from the Baikonur cosmodrome in Kazakhstan shortly after 2.20p
34、m.3.Corot，short for convection rotation and planetary transits，is the first instrument capable of finding small rocky planets beyond the solar system.Any such planet situated in the right orbit stands a good chance of having liquid water on its surface，and quite possibly life，although a leading scie
35、ntist involved in the project said it was unlikely to find “any little green men”.4.Developed by the French space agency，CNES，and partnered by the European Space Agency (ESA)，Austria，Belgium，Germany，Brazil and Spain，Corot will monitor around 120，000 stars with its 27cm telescope from a polar orbit 5
36、14 miles above the Earth.Over two and a half years，it will focus on five to six different areas of the sky，measuring the brightness of about 10，000 stars every 512 seconds.5.“At the present moment we are hoping to find out more about the nature of planets around stars which are potential habitats.We
37、 are looking at habitable planets，not inhabited planets.We are not going to find any little green men，” Professor Ian Roxburgh，an ESA scientist who has been involved with Corot since its inception，told the BBC Radio 4 Today programme.6.Prof Roxburgh said it was hoped Corot would find “rocky planets
38、that could develop an atmosphere and，if they are the right distance from their parent star，they could have water”.7.To search for planets，the telescope will look for the dimming of starlight caused when an object passes in front of a star，known as a “transit”.Although it will take more sophisticated
39、 space telescopes planned in the next 10 years to confirm the presence of an Earth-like planet with oxygen and liquid water，Corot will let scientists know where to point their lenses.8.Measurements of minute changes in brightness will enable scientists to detect giant Jupiter-like gas planets as wel
