哭啊gmatprep语法错了9个请教！！

今天第一次作prep，再有9天就要考了，错了9到语法，，，哭啊~~~~ 不知道考试的时候语法是不是也这么难。

请教几个问题：

Less than 35 years after the release of African honeybees outside San Paulo, Braile, their descendents, popular known as killer bees, had migrated as far north as southern Texas.

B In less than 35 years since releasing African honeybees outside San Paulo, Braile,

选项时A,谁能说说b为啥错的？

Employment costs rose 2.8 percent in the 12 months that ended in Sept, slightly less than they did in the year that ended in the previous quarter.

A less than they did

B less than they were

C lower than

D lower than they were

 王乐e是什么答案了。选a，为什么不能选d哪？

Less than 35 years after the release of African honeybees outside San Paulo, Braile, their descendents, popular known as killer bees, had migrated as far north as southern Texas.

B In less than 35 years since releasing African honeybees outside San Paulo, Braile,

选项时A,谁能说说b为啥错的？

A: 表示在release这个动作之后的某个时点，这个时点距离release这个动作少于35年，用来做状语。这是很标准的时间状语的用法。less than修饰35 years，用法等同于35 years after the release of African honeybees outside San Paulo

B: in表示在某个时点。可以用in the year of..。In less than 35 years since releasing逻辑混乱。当然，since releasing中的releasing用法不好。在有相应名词存在的前提下，ETS基本不倾向用分词。但这个问题不是主要错误。

Employment costs rose 2.8 percent in the 12 months that ended in Sept, slightly less than they did in the year that ended in the previous quarter.

A less than they did

B less than they were

C lower than

D lower than they were

主句的主谓是costs rose。比较中补出主谓。they指代costs。did补出相应助动词，指代rose。were不能指代rose。

差不多！~  mm不要灰心，你的情况和我类似，我接连两次模考语法都错9个。开始我还觉得是自己发挥不好，自以为og已经烂熟于心。没想到第一次做大全25题也是错了11题。备受打击。感觉光看og还是不够的，从那些已经很熟悉的语法题突然跳到陌生的语法题错误率直线上升，而且会觉得难度很大。

在已经掌握语法知识点的情况下，做做起他的语法题很有帮助，既能对知识巩固，也能使自己逐渐适应。
