1、如何短期攻克雅思阅读雅思阅读一直是同学们认为在雅思中比拟好提分的一项，但是这真的非常容易吗则怎么才能在短期内提升雅思阅读呢下面小编就和大家分享，来观赏一下吧。想短期突击雅思阅读看这篇就够了我们的阅读量大致在3500-4000词左右，这对考生从知识储藏、时间和耐心上都是不小的考验。在本文中，将会给大家分析阅读短期突击的办法!融会贯穿下列几点你的雅思阅读可能会有较大的提升哦。解题顺序和时间分配在雅思阅读中，解题顺序是很关键的一步，很多考生及其容易忽略这一点，导致很多考生在考场上时间分配不合理，耽搁了整个阅读考试的进程，不少考生在考场上的第三篇文章根本都是连蒙带猜做出来的，正确率非常之惨淡。所以，拿

2、到一篇雅思阅读文章后：第一步：看文章标题很多文章我们在看完文章标题以后就能够结合常识对文章的内容进行合理预测。比方：lets go bats这篇文章，我们就能确定首先文章是在讲蝙蝠这种动物。而关于蝙蝠大家都知道的特点就是在夜晚活动和狩猎，喜欢生活在阴暗潮湿环境，知识储藏好一点的学生可能还会联想到声波。所以，文章里自然讲的东西也不会偏离太远。其次，在文章里遇到的不认识的单词，可以往这个话题上靠拢，比方：sonar，radar(声纳和雷达)，就是跟蝙蝠的声波有关的概念。第二步：看文章引言雅思阅读有一些文章是有引言的，引言一般和标题正文的字体都不一样。根本有下列3个作用：a 文章内容简介 7-P89

3、 b 文章背景介绍 8-P26 c答案来源 8-P50看引言能够帮考生在最短时间内了解文章的大略内容，减少阅读过程中的障碍第三步：看题目很多考生在拿到阅读文章后会习惯性地先粗略地看一遍文章或者文章段落的首末句，而这个时候一般收效甚微，因为会遇到单词困境，所以，比拟推荐是先去看题目，搞分明题目里要考的内容，在阅读过程中有意识地去寻找对应的答案，效率更高。而在7-1-1这篇文章的选取中，我们应该重点关注6-9和10-13这两大类题型。因为6-9是集中型的题目，定位的答案相对靠近，都在文章的D段，在读原文的过程中，会更容易定位，而且我们知道所有题目都和facialversion相关，大大缩小了定位范

4、围。10-13题，这种句子填空题一般是按照原文先后顺序出现的，在E段里面一次出现了相关内容。这样定位相对更有规律，而且根本每个题目都出现了sonar和radar这两个概念，所以，考生只需在读原文的过程中去关注和这两个概念相关的内容，再结合每个题目里的关键词，就比拟容易解决。而相反最靠前的1-5题反而是最难定位的段落细节配对题，完全在原文乱序又分散，这种题目倡议考生在把其他题目完成之后，借助原文和对其他题目的理解再来进行定位，可以节约不少时间。第四步:阅读原文在阅读原文的过程中，重点放在容易定位的题目上，因为即使在看不太懂原文的情况下，考生还是可以根据题目的关键词和定位规律快速定位。集中就联系高

5、低文，正序就从前到后，这种题目相对更容易。所以，简言之，考生在考场上的做题顺序并非按照出题顺序来做，而是应该按照定位的难易程度来做，要在有限的时间内把我们能够拿分的题目先做完，即：容易定位的题目一定要先做，不容易定位的放在最后做。雅思考试阅读模拟练习及答案Dont wash those fossils!Standard museum practice can wash away DNA.1.

6、rs and museum curators alike vastlyreduces the chances of recovering ancient DNA.2.

Much human cultural development took place in temperate regions. DNAdoes not survive well in warm environments in the first place，

For this reason， Geigl says， most ancientDNA studies have been done on permafrost samples， such as the woolly mammoth， oron remains sheltered from the elements in cold caves including cave bear andNeanderthal fossils.15. Better conservation methods
