技巧
1)拼写联想，即将拼写类似的单词一起记忆。
如：think，thin，ink;
could，would，should;
book，look，cook;
boy，toy等。
2)意义联想，即从词义方面联想与其有关联的词。
如想到：table—desk;想到：tall—short;想到同类词：由ship联想到各种交通工具—bus，car，bike，plane，train等。
3)形-义联想法，就是对单词的结构赋予一定的想象。
如eye，可以认为这个单词中的两个e就是两个眼睛，y就像一个鼻子。look，see，eye都是和眼睛有关的单词，可以用形似的记忆法。pencil通常比pen长，所以pen后面长尾巴的就是pencil。
4)音-义联想法，就是设法把单词的音和义联想起来。
这种方法主要适用于一部分单词，记忆时，要加以想象，如cab想象为“汽车开吧”等。four和five很容易混淆，four用拼音来记忆f+o--“佛”的谐音，就能分辨清楚。
