参考谜底及解析：
1.改like为as
describesthassth是把……描述成……的意思。
2。改heating为heated
在时刻，前提，让步等啄暌癸年夜句中，昔时夜句主语和主句主语是一致的时辰,可以将年夜句的主语和be的转变形式省略。
3.改with为of
becomposedof意思为“搜罗,由……组成"
4.改ismadeup为aremadeup
which指代上文中的thegas，theliquid，andthesolid，暗示复数概念，所以要用are
5.将第一个will去失踪
在时刻前提啄暌癸年夜句和前提啄暌癸年夜句中要用此刻时暗示未来时。
6。by改为when
whenwarm相当于whenitiswarmed
7。改so为such
8.改with为to
短语familiarto后面才能接“某人"familiarwith是接sth
9。改requiring为required
曩昔分词短语作后置定语时，和被润色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
