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.

題目類型：explain

題目翻譯：

作為一種建材，竹子的堅(jiān)固程度比鋼鐵和水泥有過之而無不及。除此之外，在熱帶地區(qū)竹子比鋼鐵和水泥便宜很多且容易得到。因此，在熱帶地區(qū)，用竹子建成的房子比用鋼鐵或水泥建成的房子經(jīng)濟(jì)效益更高。但是，地價(jià)很高的地區(qū)除外，問為什么地價(jià)高的地區(qū)除外。

解題思路：

地價(jià)高的地區(qū)的房屋有以下特點(diǎn)：高、密，等。

逐項(xiàng)分析：

A、地震與地價(jià)無關(guān)，排除。

B、正確選項(xiàng)。竹子不適合建造高層建筑，而地價(jià)高的地區(qū)的建筑一般都是高層建筑。

C、為了防止白蟻和甲殼蟲破壞竹子，竹子一定要在防腐劑中浸泡。無關(guān)項(xiàng)。

D、腳手架和房子不是一回事。

E、竹子的生長(zhǎng)與竹子的使用不是一回事。

正確選項(xiàng)：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.

題目類型：flaw

題目翻譯：

辯論家：H公司制造部的某名員工每月加班的平均時(shí)間是14小時(shí)。絕大部分H公司的人員都在制造部工作。除此之外，每位員工每月的加班時(shí)間比較固定。因此，H公司的員工每個(gè)月至少要加一段時(shí)間班。

解題思路：

無既定思路，逐項(xiàng)分析。

逐項(xiàng)分析：

A、題干并沒有說“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

B、題干并沒有說“the manufacturing division is a typical division of the corporation with regard to the average amount of overtime”。

C、模棱兩可項(xiàng)。未指明哪一個(gè)claim。

D、正確選項(xiàng)。某名員工的加班時(shí)間并不能代表該部門的平均加班時(shí)間。

E、題干沒有忽略這種可能性。

正確選項(xiàng)：D
