I believe I had done a very large amount of practice and summary as well. That was already my second shot. I also believe I can understand GMAT quite deeply but not superficially.
I guess I need some good luck a month later. But thanks for commenting anyway.
一是比较名次,这里边要注意that指代rate、level、number等比例之类的词,二是比较状态,注意肯定是要有be,比如常考得as likely as...后面一定是跟个be的,三是比较不定式动作,可以说也是一种习惯用法,如It is as difficult to prevent crimes against property as it is to prevent thoes against a person.四是比较there be,这也是一种习惯用法。比较的最大难题当然是省略,不过只要你会总结,还是上面这几种情况,很简单的~
