本文通过100个单句，涵盖了雅思考试的7000个单词。无论是准备考雅思还是单纯想要提高词汇量、提高英语综合能力，这100句都要好好收藏和记忆哦！
在背诵这100个句子之前，看看老师的建议吧：
这些词必须得引申一下，几乎每段话都有几个词需要好好的查下词典，这样你就会发现你背的不止7000个了，比如第6句话中的locality,这里它是一个名词，其实他的家族还有动词（localize）、形容词(local)、名词(locale)等等，并且每一个词性都有很多很多短语，光背这个词就够你背一会的了；
另外还有第10句，thigh这个词，是大腿的意思，你查查字典就会发现字典上把整个人身体的所有器官都写的明明白白的，这样你就不止是背一个词了，而是背了几十个之多。
由此看来，学英语真的得用心，还得动脑，不能死记硬背，每天只背5句话，把这5句话吃透了背熟了，**对你的英语有很大提高，这里面的很多句子都是典型的例句，我觉得还是挺有用的，我现在天天都在背呢，嘿嘿我说的也不一定都对，就是仁者见仁智者见智吧。
