A Four-day Week

Fancy a three-day weekend一not just once in a while but week in week out? You may think your bosses would never agree to it,but the evidence suggests that employers,employees and the environment all benefit.
The four-day week comes in two flavors.One option is to switch from five 8-hour days to four 10-hour days,meaning overall hours and salaries stay the same.Two years age,the state of Utah moved all of its employees,apart from the emergency services,to working 4/10,as it has become known.The hope was that by shutting down buildings for an extra day each week,energy bills would be cut by up to a fifth.
The full results of this experiment won't be published until October,but an ongoing survey of 100 buildings suggests energy consumption has fallen by around 13 percent. The survey also found that 70 percent of employees prefer the 4/10 arrangement,and that people look fewer days off sick.
The second form of the four-day week is to work the same number of hours per day for four days only,with a 20 percent pay cut. With the recession hutting revenues , accountancy(会计工作) company KPMG announced in February that it was offering its 11,000 U.K. employees the option of a four-day week to avoid job losses.So far 85 percent of employees have applied to join the scheme, and 800 now do a four-day week.
Not everyone will like the idea of working longer days or taking a pay cut in exchange for a 3-day weekend,but it appears most do.According to Rex Facer at Brigham Young University in Provo,Utah,it was the crash of 1929 that led to the five-day week.During the next big financial crisis in the 1970s,there was much talk of moving to a four-day week,but for a variety of reasons that didn't pan out."Things are different now,"says Facer."I wouldn't be surprised if we could get 50 percent or more of the workforce working four-day weeks in the next few years."

It can be inferred from the passage that_______.
A:the majority of people dislike a pay cut for a 3-day weekend
B:the 5 -day week schedule resulted from the 1929 economic crisis
C:the 4-day week schedule was widespread in the 1970s
D:the 4-day week schedule was put forward by Rex Facer

答案:B
解析:
本题是细节考查题。题干是:扰他州进行四天工作制实验,其目的是什么?选A的依据是第二段最后一句:"The hope was that by shutting down buildings for an extra day each week, energy bills would be cut by up to a fifth.”该州期望通过每周让办公大楼多关闭 1天的方式,削减高达1乃的能源费用。选项A的意思是降低能源的消耗,与原文相符。
本题是细节考查题。题干是:一个正在进行的调查显示_____。选C的依据是第三段第二句:."The survey also found that 70 percent of employees prefer the 4/10 arrangement, and that people look fewer days off sick.”这项调研还发现,70%的雇员更喜欢4天10'J、时工作制,而且雇员请病假的天数也减少了。选项C的意思是大部分员工赞同4天10小时工作制,与原文相符。
本题是细节考查题。题干是:我们对于四天工作制第二种版本的认识是什么? 选B的依据是第四段第二句:"With the recession hutting revenues, accountancy company KPMG announced in February that it was offering its 11,000 U .K.employees the option of a four-day week to avoid job losses.”毕马威会计师事务所(KPMG)在2月份宣布向其1.1万名英国员工提供4天工作制的选择,以避免裁员。选项B的意思是毕马威会计师事务所采用这一工作制是为了避免裁员,与原文相符。
本题是细节考查题。题干是:从短文中可以推理出什么? 选B的依据是最后一段第二句:"it was the crash of 1929 that led to the five-day week.”正是1929年的经济危机导致了五天工作制的诞生。选项B的意思是5天工作制是1929年经济危机的结果,与原文相符。
本题是细节推理题。题干是:费瑟说:“但现在情况不同了,”是想暗示什么?选C的依据是最后一段第一句:"Not everyone will like the idea of working longer days or taking a pay cut in exchange for a 3-day weekend, but it appears most do.”不是每个人都喜欢通过延长每天工作时间或减少薪水来换得3天周末,但似乎大多数人还是喜欢的。most do及最后一句的wouldn't be surprise…均表明,与20世纪70年底啊的情况不同,现在实行4天工作制的可能性非常大。选项C的意思是4天工作制很有可能普及,与原文相符。

7._________
A: on
B: after
C: off
D: for

答案:C
解析:
我们很清楚此处要选的是表示心跳的单词,常规理解的跳是jump,但是在英 文里表示心跳要用 heart beat,所以此处选beat的动名词形式beating。所以本题选C。
A项“快地”;B项“轻松地”;C项“温热地”;D项“正常地”。可见只有D项符合题意。故选D。
备选项中gain与weight搭配组成词组正是长胖了的意思。bring和take 不与weight直接搭配,carry weight的意思是重要,与题意不符。所以本题选A。
本题很明显要选有减少、降低意思的词汇。A项“加倍”;B项“降低”;C项 “修正”;D项“移动”。所以本题选B。
四个选项的意思分别为A项“原理”;B项“形式”;C项“方法”;D项“种类”。根据句意选A合适。
don't work for sb.表示对某人不起作用。根据后文也知道此处选work比较合适。此外题目给的一些备选项是及物动词,也可以作为排除的标准。
前文一直在用on diet这个词组,表示控制饮食,此处讲体重回升肯定要选和 on diet相反意思,on与off是一对反义词,go off the diet表示“停止节食”。故选C。
此题还是考察和weight的词语搭配。get不和weight搭配,meet和sup-port是够重、承受重量的意思,maintain weight是保持体重的意思。可见选D正确。
本题需要填入一个修饰“摄入”的副词。从词义上看,四个单词分别是A项 “部分地”;B项“希望地”;C项“明智地”;D项“实际地”。可见D选项正确。
本句很显然要选有“提高、增长”含义的词汇,因为增大运动量会多消耗卡路里,最终减重。四个选项中C项raise是“增长”的意思。D项grow也有“增长”的意思,但此句很明显需要的是及物动词,grow做及物动词的意思是“种植”,做不及物动词时才有“增长”的意思。所以此处不能选grow。故选C。
此处很明显要填入表示“形式”的单词。所以B、C选项不适合。ways表示方式,forms表示形式。form更强调客观物质的形式,方式,格式,例如:Ice, snow and steam are different forms of water.(冰、雪、蒸汽是水的不同形式。) way则强调事情解决的方法, form则不可以用来作为事情解决方法。例如:They are trying to find a way of settling the dispute.(他们正设法寻找解决争端的办法。)所以此处选forms,故D项正确。
此处主要考察和difference的搭配。make a difference是固定搭配,所以此处选C。
此处需要选择和stairs搭配组成“走楼梯”词组的单词。在汉语中我们常说爬楼梯,在英语里也用climb来表示。其他搭配都不符合题意。所以本题选B。
从后面的“Exercise can be a lot easier if there is someone to talk to.”可以看到此处要选的是同伴。所以选A, colleague一般表示同事,用于此处显然不适合。
你的目标是节食和减肥,自然要穿紧衣服。所以此处选A。
