No! Some Brits are now saying that traffic lights are to blame for much of the congestion(交通拥挤).They suggest that traffic lights be removed at busy roads. They believe people are a better judge of when it’s safe to go, not a traffic light programmed by an absent regulator.A report from the Institute of Economic Affairs, argues that abolishing traffic signals would decrease congestion, reduce exhaust emissions(废气排放)and improve safety.The report said that removing lights should also prevent other bad behavior caused by signals, such as speeding up to catch a green light. It would also avoid the wasted time when drivers have to sit at a red light even if no one is using the green.The idea may sound strange, but it’s not new. Seven cities and regions in Europe are experimenting with no-lights roads.Drachten in the Netherlands has got rid of 16 of its traffic light crossings and changed the other two to roundabouts under a ―shared space‖ scheme. At crossings, cyclists dutifully raise their arm when they want to make a turn, and drivers follow a first-arrived, first-through approach and communicate by hand signs, nods and waving.The result? Typical journey time has been cut in half, and accidents and congestion have mostly disappeared.There have been small collisions but no problem, said Hans Monderman, creator of thescheme. ―We want small accidents, in order to prevent serious ones. It works well because it’s dangerous. The driver has to be responsible for his or her own risk.‖―The many rules take away the ability to be considerate,‖ Monderman added. ―We’re losing our responsibility for socially responsible behavior.‖So far, Drachten’s locals have called the experiment a success. ―I am used to it now,‖said Helena Spaanstra, 24. ―You drive more slowly and carefully, but somehow you seem to get around town quicker.‖Tony Ooostward, 70, was equally enthusiastic. ―I am a walker and now you are the boss at the crossroads, everyone waits for you. But at the same time walkers wait until there are a number of people wanting to cross at the same time.‖Owen Paterson, UK’s Shadow Transport Minister, visited Drachten. He said Britain should learn from the model. ―The idea is to create space where there is mild anxiety among everyone so they all behave cautiously. No one drives fast along a busy street thinking that they have right of way.‖36. Which of the following is the best title for the passage?A. Don’t Count On Traffic LightsB. New Traffic Systems NeededC. Turn Those Traffic Lights OffD. Let People Have More Say In Traffic37. According to the report from the Institute of Economic Affairs, abolishing traffic lights would NOT lead to ____.A. more time being savedB. reduction of traffic jamsC. improvement of the environmentD. right of way being taken for granted38. The underlined word ―collision‖ in Paragraph7 means closest __________.A. jamB. accidentC. troubleD. congestion39. From the passage we can see that the experiment in Drachten worked well because ____.A. walkers have become the boss of the crossroadsB. cyclists, walkers and drivers each have specially designed routesC. everyone finds that they have to do their share in regulating trafficD. drivers are more careful and wait for cyclists or walkers to pass firstBIt is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, the basis for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.Memory can be defined as the capacity to keep information available for later use. It not only includes ―remembering‖ things like arithmetic or historical facts, but also involves any change in the way an animal typically behaves. Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile.Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory storage capacity of a computer with that of a human being. The instant access memory of a large computer may hold up to 100,000 ―words‖---string of alphabetic or numerical characters—ready for instant use. An average U.S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction(小部分) of the total amount of information that the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight.The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a person’s memory is in terms of words and combinations of words. But while language greatly expands the number of things a person can remember, it also requires a huge memory capacity. It may well be this capacity that distinguishes humans, setting them apart from other animals.40. Which of the following is TRUE about memory?A. It helps us be aware of things happening around us every day.B. It is based on the decisions we made in the past.C. It is rooted in our past habits and skills.D. It connects our past experiences with the present.41. What is the author’s view about computers and human beings in terms of intelligence?A. Computers have better memory than a child does.B. Computers are as intelligent as a teenager is.C. Computers can understand as many as 100,000 words.D. Human beings are far superior to computers.42. What is the major characteristic of man’s memory capacity according to the author?A. It can be expanded by language.B. It can remember all the combined words.C. It may keep all the information in the past.D. It may change what has been stored in it.43. Human beings make themselves different from other animals by _______.A. having the ability to perceive dangerB. having a far greater memory capacityC. having the ability to recognize faces and places on sightD. having the ability to draw on past experiencesCStudents’ InsuranceWhat Is Covered under Contents?Under the ―Contents‖ section your possessions – which you do not have to be listed—will be protect ed on a ―new for old ‖ basis where items will be replaced as new—regardless of their age or condition.―Contents ‖ include books, radios, audio and video players, TVs, jewellery, home computers, furniture, household goods, other electrical equipment and sports equipment.

For every dissatisfied customer, a store will lose up to three more due to negative reviews. The resulting ―snowball effect‖ can be disastrous to retailers.According to the research, shoppers who purchased clothing encountered the most problems. Ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered(塞满了的)shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved the parking problems by getting moonlighting(业余兼职的) local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided confrontation between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.Most importantly, salespeople should be diplomatic and polite with angry customers.―Retailers who’re responsive and friendly are more likely to smooth over issues than those who aren’t so friendly.‖ said Professor Stephen Hoch. ―Maybe something as simple as a greeter at the store entrance w ould help. ―Customers can also improve future shopping experiences by filing complaints to the retailer, instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they have no idea what is wrong.47. What does Paula Cour tney imply by saying ―…the shopper must also find a replacement‖(Line 2, Para. 4)?A. New customers are bound to replace old ones.B. It is impossible the shoppers to find the same products in other stores.C. Most stores provide the same kind of service.D. Not complaining to the manager causes the shopper some trouble too.48. Shop owners often hire moonlighting police as parking attendants so that shoppers _________.A. can stay longer browsing in the storeB. won’t have trouble parking their ca rsC. won’t have any worries about securityD. can find their cars easily after shopping49. What contributes most to smoothing over issues with customers?A. Manners of the salespeople.B. Hiring of efficient employees.C. Huge supply of goods for sale.D. Design of the store layout.50. To achieve better shopping experiences, customers are advised to__________.A. put pressure on stores to improve their serviceB. settle their disputes with stores in a diplomatic wayC. voice their dissatisfaction to store managers directlyD. shop around and make comparisons between stores第四部分:任务型阅读(共10小题;每小题1分,满分10分)Hormone-like chemicals in plastics and other products cause significant concern for public health, possibly causing cancer and malformations, according to a scientific report from theEndocrine Society, now meeting in Washington, D.C. Although scientists still have many questions about the chemicals, the report says that it's important for people to take a "precautionary approach" by reducing their exposures.Hormone-disrupting chemicals include bisphenol A, or BPA, often used in plastic baby bottles and metal cans. The new report is the latest in a growing number of statements from scientific groups warning of potential harm. In 2007, a group of 38 leading researchers published a statement noting serious risks from BPA.The Endocrine Society decided to release the scientific statement ---the first it has ever issued ---because these chemicals "affect everyone," says society president Robert Carey. The report notes that 93% of Americans tested have been exposed to BPA. Carey says the society wants to provide accurate information to lawmakers and regulators.The report notes that hormone-disrupting chemicals behave differently than other toxins(毒素). For most toxins, the danger is in the dose, with larger doses posing more risk than small ones, says Andrea Gore, an author of the new statement from the University of Texas. For hormones, the timing of exposure is often far more critical than the amount.Scientists at the annual meeting presented new studies on BPA, as well, including one linking the chemical to abnormal heart rhythms in rats and mice. That finding supports a September study in The Journal of the American Medical Association linked BPA to an increased risk of heart disease and diabetes in humans.Another new study found that people are likely exposed to greater doses of BPA than are considered safe by the FDA. And a third study, showing that BPA causes permanent changes in the DNA of mice, helps doctors understand how this damage is passed on to offspring, says author Hugh Taylor of Yale University School of Medicine. "I don't think anybody is saying this is the most poisonous stuff known to man," Taylor says. "But are we doing something that could affect our children into the next generation?"Although a group called the International Union of Pure and Applied Chemistry found there have been no "conclusive" studies proving that the chemicals cause disease, Taylor insists there is当前,家长普遍认为现在孩子的行为习惯没有他们自己小时候的好。

一、单项选择题(每题2.5分,共32.5分)题目1正确获得2.50分中的2.50分标记题目题干我国某企业记账本位币为美元,下列说法中错误的是()。
选择一项:A. 该企业以人民币计价和结算的交易属于外币交易B. 该企业以美元计价和结算的交易不属于外币交易C. 该企业的编报会计报表直接以美元反映D. 该企业的编报会计报表货币折算为人民币反馈【答案解析】企业业务收支以人民币以外的货币为主的企业,可以选定某一种货币作为记账本位币,但编制的财务报表应当折算为人民币反映。
在对于记账本位币以外的货币表示和计量的经济业务,则应通过一定的换算标准,将其换算成记账本位币以后才能计入有关账户。
记账本位币一经确定后,一般不得随意变更。
正确答案是:该企业的编报会计报表直接以美元反映题目2正确获得2.50分中的2.50分标记题目题干企业因经营所处的主要经济环境发生重大变化,确需变更记账本位币的,应当采用(),将所有项目折算为变更后的记账本位币。
选择一项:A. 变更当日的即期汇率的近似汇率B. 变更当日的即期汇率C. 当期期末汇率D. 当期平均汇率反馈【答案解析】企业因经营所处的主要经济环境发生重大变化,确需变更记账本位币的,应当采用变更当日的即期汇率将所有项目折算为变更后的记账本位币。
正确答案是:变更当日的即期汇率题目3正确获得2.50分中的2.50分标记题目题干直接标价法的特点是()选择一项:A. 本国货币币值大小与汇率的高低正相关B. 本国货币数随汇率高低而变化C. 本国货币币值大小与汇率的高低无关D. 本国货币数固定不变反馈【答案解析】直接标价法是用一定单位的外国货币为标准来计算应折合若干单位的本国货币的方法。
如1美元可以兑换6.25元人民币($1=¥6.25)。
在直接标价法下,外币金额固定不变,所折合的本国货币数额随着外国货币与本国货币之间的币值对比情况发生变化,当汇率上升时,表示要换取同样数额的外国货币,需付出更多的本国货币,即本国货币币值下降,反之,当汇率下降时,表示换取同样数额的外国货币,可少付出本国货币,表示本国货币币值的上升。
