3、risanexceptioninthisrespect,whichisanotherreasonwhyitsthreestateshavegiventhreedifferentnames.10参考答案及解析:改like为asdescribesthassth是把描述成的.意思。改heating为heated在时间，条件，让步等状语从句中，当从句主语和主句主语是一致的时候，可以将从句的主语和be的变化形式省略。改ismadeup为aremadeupwhich指代上文中的thegas，theliquid，andthesolid，表示复数概念，所以要用are5.将第一个will去掉在时间条件状语从句和条件状语从句中要用现在时表示将来时。6.by改为whenwhenwarm相当于whenitiswarmed7.改so为such8.改with为to短语familiarto后面才能接“某人”familiarwith是接sth9.改requiring为required过去分词短语作后置定语时，和被修饰的名词时逻辑动宾关系。10.have后加been动词give和主语threestates是动宾关系
