CR 有報告顯示去年夏天氣溫是乾且熱,而今年夏天濕且涼爽,而溼的路面比較容易有汽車accident, 所以今年夏天的汽車accident一定比去年多。題目找weaken

 

 

 

CR: A說坐汽車繫安全帶在發生事故時可以有效保護小朋友

    B說但有report顯示小朋友的受傷是來自於發生事故時安全帶傷到小朋友,所以安全帶反而對他們造成傷害,題目問AB兩人disagree選項中那個陳述

 

 

 

RC : 美國GDP

Citing the fact that the real gross

  (5)  States economy performed ideally in

1997.  However, the real GDP is almost

always higher than ever before; it falls

AA: 64. The following appeared in a memorandum from the Director of Human Resources to the executive officers of Company X.

“Last year, we surveyed our employees on improvements needed at Company X by having them rank, in order of importance, the issues presented in a list of possible improvements. Improved communications between employees and management was consistently ranked as the issue of highest importance by the employees who responded to the survey. As you know, we have since instituted regular communications sessions conducted by high-level management, which the employees can attend on a voluntary basis. Therefore, it is likely that most employees at Company X now feel that the improvement most needed at the company has been made.”

AI : 我在official guide上找不到這個題目,題目開頭是 Constant innovation and change in an organization .大意是說constant innovation change對組織所帶來的damage 跟他們所能帶來的好處似乎差不多,然後問你是否同意這樣的說法.有誰知道這是在第幾題嗎??
