考研网

距2014年10月的工程硕士GCT考研还有1个多月，新东方在线小编为大家整理了2014年考研工程硕士GCT英语语法复习，希望广大gct考研考生抓紧时间认真记忆。
    先行词和关系词二合一
    1)Whoever spits in public will be punished here.
    (Whoever 可以用 anyone who 代替)
    2)The parents will use what they have to send their son to technical school.
    (what 可以用all that代替)
    what/whatever; that/what; who/whoever
    1)what = the thing which;whatever = anything
    What you want has been sent here.
    Whatever you want makes no difference to me.
    2) who= the person that　 whoever= anyone who
    (错)Who breaks the law will be punished.
    (错)Whoever robbed the bank is not clear.
    (对)Whoever breaks the law will be punished.
    (对)Who robbed the bank is not clear.
    3) that 和 what
    当that引导定语从句时 ，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从　句，用作连接代词，作从句的具体成分，且不能省略。
    I think (that) you will like the stamps.
    What we need is more practice.
