在雅思阅读考试时长是一个小时,想要在规定时间里完成所有考题,对于考生来说也是有一定难度的,文章篇幅比较长,题型比较复杂。那么雅思阅读文章的篇幅有多长呢?接下来小编为大家介绍一下,大家在备考中一定要提升阅读速度。

  A类的文章大致有1500至2000字左右,另外再加上题目的字数,如果想在一小时之内把每个字都读懂,一般是不太可能的,因此需要考生要掌握一些快速阅读的方法。一个是略读法,一个是寻读法。略读指的是快速理解段落大意;寻读就是定位所问的细节,需要灵活的去运用这两种方法。雅思阅读八个题型中只有标题对应题是最典型需要略读法的题,其余的基本上都是这两种方法的结合。

  我们来看一篇原文找找感觉。
