18、读(scanning) 寻读又称查读，同略读一样，寻读也是一种快速阅读技巧。 寻读是一种从大量的资料中快速查找某一项详细事实或某一项特定信息，如人物、大事、时间、地点、数字等，而对其它无关局部略去不读的快速阅读方法。 托福阅读高分方法四：略读(skimming) 略读又称跳读(readingandskipping)或扫瞄(glancing)，是一种特地的，特别有用的快速阅读技能。 托福阅读成果提升的方向 单词 依据自己的英语根底制定出每天可以坚持的，实在可行的背单词方案。 结合托福阅读文章记忆单词是颇为有效的方法。如脱离语言环境孤立地背单词汇，就很简单把单词的意义和正确用法遗忘或者混淆。而且，枯燥的单词书和字母表简单让人疲乏和产生挫败感。在精读托福文章的同时背单词，除了单词的收获，还能深化理解文章中的各类人文常识，兴趣科普学问，从而产生每天坚持阅读，坚持背单词的爱好和动力。另外，有效记单词的另一个重要原那么是：肯定要反复记忆。背过的单词肯定要定期复习
