雅思阅读定位方法谈

千里之行，始于第2页/共2页精品文档推荐雅思阅读定位方法谈信息检索与定位是雅思阅读考察的最基本的语言力量之一，这将在Ieltser们出国留学的时候起到特别大的作用。我给大家带来了雅思阅读定位方法谈，盼望能够关心到大家，下面我就和大家共享，来观赏一下吧。

雅思阅读定位方法谈：请给我一双慧眼or写轮眼

那么假如同学们定位定不到，究竟是为什么呢?我认为有以下三个缘由：

雅思阅读定位之真的缺乏一双发觉的眼睛

这个应当是许多同学会比较头痛的问题，那是真的没有擅长发觉爱的眼睛啊。人家出题句就在那个地方，死都看不到，这也真的是醉醉了。其实，这就是在考察各位scanning的力量，我们所谓的scan是带着一个特别的词或信息，在文中查找，找到了停住即可，其他那些在查找中所遇见的词或句子都是浮云，千万不要较真的一一读懂，铺张表情～

雅思阅读定位方法：scanning在生活中无处不在，你看航班，火车信息，其实都是在用scanning只是自己不知道而已，所以大家要好好的训练一下，定位词的选择不要出错(否则你看破大天也定不出来)。这里，刚刚提示各位，我们雅思阅读中许多题目都是有挨次的，请千万不要犯倔，肯定要从第一题定到最终一题，先定最好定位的，然后再依据挨次原则去推(把全文定位变为局部定位)

雅思阅读定位之遇到难题，定位词同义替换了

假如各位烤鸭对于雅思阅读的分数停留在7分以下，那么遇到这种定位词同义替换的题目，我只能说大家运气不好，一般这种状况都会发生在第三篇。那这种状况，其实不怪各位，你们的题干定位词都找对了，但就是在文中找不到，这个时候肯定要有一个意识，或许定位词被同义替换了，

如：C10T1P3的第34题：Peopleworkingunderadominantbossareliableto

这道题目我们的定位词用dominantboss是没有问题的，可是你通篇去找你会发觉根本找不到类似的词，这个时候我们发觉，他就是定位词被同义替换了，大家看下下面这个出题段，看看同义替换成了什么?

没错，就是Authority，dominantboss就是支配型的老板，那么衍升一点就是有权利的老板，对应我们的Authority，所以这道题目的对应出题段就是文中的倒数第三段。遇到这种题目怎么办呢?

雅思阅读定位方法：同义替换的总结，这肯定是不能偷懒的

另外，还是想说，把全文定位变为局部定位，各位假如从全文去找dominantboss这无疑是大海捞针，所以为什么不先做33题，然后做35题，然后依据挨次原则在35和33的中间去卡34的位置呢。这样加上前面对同义替换的预备，我们找起来，也会便利许多。

雅思阅读定位之不信任自己，总觉得自己是错的

这个问题，主要消失在推断题上。我们都知道推断题是有一个选项NG的，而NG的一种状况就是原文未提及。许多同学在做此类题目的时候，定位定不到就往死里定(有的时候我真的不怕你们定不到，而是怕你们凭想象力去定，天啊噜)。总觉得，自己定不到确定是自己的问题。同学你这样真的好嘛?

雅思阅读定位方法：任何一种题型，肯定有定位的突破口，找到它(也就是最好定位的题目)，先去定位，然后依据推断题的挨次原则去上下推想四周题目的出题范围(局部定位)，信任自己，假如没有找到，就大胆的选择NG(但千万不要选太多NG啊，一般6-7个推断题出2-3个NG)

最终刚刚想说的，定位是雅思索察的最基本的语言力量之一，这将在各位出国留学的时候起到特别大的作用，所以各位同学肯定要留意这个问题。当然，大家也不要被刚刚上面说的给吓到了，雅思作为一门语言评测类考试，只要各位下功夫，多练习，多总结(当然要每天关注刚刚的推送啦)，是肯定会有提高的。
