1、As a construction material, bamboo is as strong as steel and sturdier than concrete. Moreover, in tropical areas bamboo is a much less expensive construction material than either steel or concrete and is always readily available. In tropical areas, therefore, building with bamboo makes better economic sense than building with steel or concrete, except where land values are high.

Which of the following, if true, most helps to explain the exception noted above?

(A) Buildings constructed of bamboo are less likely to suffer earthquake damage than are steel and concrete buildings.

(B) Bamboo is unsuitable as a building material for multistory buildings.

(C) In order to protect it from being damaged by termites and beetles, bamboo must be soaked, at some expense, in a preservative.

(D) In some tropical areas, bamboo is used to make the scaffolding that is used during large construction projects.

(E) Bamboo growing in an area where land values are increasing is often cleared to make way for construction.

题目翻译：

作为一种建材，竹子的坚固程度比钢铁和水泥有过之而无不及。除此之外，在热带地区竹子比钢铁和水泥便宜很多且容易得到。因此，在热带地区，用竹子建成的房子比用钢铁或水泥建成的房子经济效益更高。但是，地价很高的地区除外，问为什么地价高的地区除外。

解题思路：

地价高的地区的房屋有以下特点：高、密，等。

逐项分析：

A、地震与地价无关，排除。

B、正确选项。竹子不适合建造高层建筑，而地价高的地区的建筑一般都是高层建筑。

C、为了防止白蚁和甲壳虫破坏竹子，竹子一定要在防腐剂中浸泡。无关项。

D、脚手架和房子不是一回事。

E、竹子的生长与竹子的使用不是一回事。

正确选项：B

2、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
