GMAT逻辑题一直以来是不少考生的弱项，因为逻辑题考查的不只是考生对于英文题目的阅读和理解能力。考生必须具备一定的逻辑推理思维能力才能做好此类题目。下面小编就通过一些GMAT逻辑真题的完整分析来为大家讲解这一难点题型的解题思路和技巧。

例题分享：

Debater: The average amount of overtime per month worked by an employee in the manufacturing division of the Haglut Corporation is 14 hours. Most employees of the Haglut Corporation work in the manufacturing division. Furthermore, the average amount of overtime per month worked by any employee in the company generally does not fluctuate much from month to month. Therefore, each month, most employees of the Haglut Corporation almost certainly work at least some overtime.

The debater’s argument is most vulnerable to criticism on which of these grounds?

(A) It takes for granted that the manufacturing division is a typical division of the corporation with regard to the average amount of overtime its employees work each month.

(B) It takes for granted that if a certain average amount of overtime is worked each month by each employee of the Haglut Corporation, then approximately the same amount of overtime must be worked each month by each employee of the manufacturing division.

(C) It confuses a claim from which the argument’s conclusion about the Haglut Corporation would necessarily follow with a claim that would follow from the argument’s conclusion only with a high degree of probability.

(D) It overlooks the possibility that even if, on average, a certain amount of overtime is worked by the members of some group, many members of that group may work no overtime at all.

(E) It overlooks the possibility that even if most employees of the corporation work some overtime each month, any one corporate employee may, in some months, work no overtime.

题目翻译：

辩论家：H公司制造部的某名员工每月加班的平均时间是14小时。绝大部分H公司的人员都在制造部工作。除此之外，每位员工每月的加班时间比较固定。因此，H公司的员工每个月至少要加一段时间班。

解题思路：

无既定思路，逐项分析。

逐项分析：

A、题干并没有说“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

B、题干并没有说“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

C、模棱两可项。未指明哪一个claim。

D、正确选项。某名员工的加班时间并不能代表该部门的平均加班时间。

E、题干没有忽略这种可能性。

正确选项：

D
