根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。

Dear Sir,

I have to travel every day from So UK Road to the airport. Two buses travel along this route: No.49 and No.16. However, by the time No.16 reaches So UK Road, it is always full.__小题1:__

The timetable states that there are buses from So UK Road to the airport every ten minutes.__小题2:__ The instructions state that if there are empty seats on a bus, the bus must stop at every stop where people are waiting. __小题3:__

The instructions state that no bus may carry more than 40 seated passengers and 20 standing passengers. Yesterday, I was the first to get off the bus when it reached the airport. __小题4:__ There were 129 of them.

Clearly printed on the back of every bus is a sign that says “Maximum speed: 50mph.” ___小题5:__ Saturday morning a No. 49 bus traveled the distance in ten minutes, at an average speed of 60 mph. At times it must have done at least 80 or even 90 mph.

It is obvious that our bus companies have neither respect for the instructions nor consideration for their passengers. Can nothing be done about this?

Jerry

A.I counted the other passengers as they got off.

B.Why is it that half-empty buses go straight past me when I am standing at the bus stop?

C.The problem is that we have to pay more for our trip.

D.The distance from So UK Road to the airport is 10 miles. E. This leaves No.49 which sometimes has empty seats on it.

F. If this is so, why do I have to wait half an hour for a bus nearly every day?

题型:单项选择题

近几年来,许多在高楼大厦里工作的白领常常会莫名其妙地出现类似头疼、鼻塞、眼睛干涩发痒以及疲乏无力这样的症状。时间一长,人们将这种现象称为“病楼综合征”。于是,许多无端的责怪都冲向办公大楼,似乎是这些高楼大厦本身给楼内工作人员的健康带来了灾难。然而,英国科学家最近发表的一项研究报告显示,办公大楼本身并不是这种综合征的病源。人们在工作中所面临的日益增长的压力才是真正的元凶。
在这项研究中,研究人员调查了四千多名在办公大楼里工作的英国政府雇员的健康状况。这些公务员分布在伦敦44个办公大楼里工作。研究人员对其工作环境及所受的工作压力进行了分析。研究还分析了大楼里的有关环境指标,如温度、湿度、粉尘、空气中的真菌和细菌含量等。研究人员发现,虽然工作环境中的燥热和湿度情况,以及空气中的粉尘和细菌对楼内工作人员的健康有一些影响,但是真正具有明显统计意义的结果却是,这些政府雇员所面临的工作压力,以及常常所处的无助状态导致了这些人产生“病楼综合征”,而工作地点本身与这种综合征并无实质性的关联。
研究人员表示,“病楼综合征”的说法实际上是一种误导。这种综合征症状的存在,以及因此造成的许多工作人员经常请假,所带来的经济损失是相当大的。但是具体的工作环境并不是产生这些综合征的根源。
研究人员表示,像“病楼综合征”这样的情况,需要从心理和社会环境的综合角度去分析。总的来讲,人们所面对的工作压力是造成这种综合征的主要根源,而工作环境状况差则起到了推波助澜的作用。

出现“病楼综合征”后人们一般会怎么做

A.指责大楼设计者

B.指责大楼建筑者

C.指责公司领导

D.指责办公大楼
