Passport Control If you are arriving at London Heathrow Airport and are not transferring   to another flight outside Britain or Northern Ireland,you must pass through Passport Control and Customs immediately after leaving your plane. If you are not British or a citizen of the European Community,you must fill out a special form before your passport is examined.This form is called a landing card and should be given to you during the flight to London. After landing,follow the AKRIVALS signs.Make sure you are in the right channel   when you reach Passport Control.There is one channel for holders of European Community passports,and a second channel marked "Other Passports". Baggage Reclaim   Area After passing through Passport Control,follow the signs to the Baggage Reclaim Area.If you have luggage which was carried in the aircraft:along with other goods,it will be delivered to you in the Baggage Reclaim Area.Look for the sign with your flight number.If you have only hand luggage,go directly through the Baggage Reclaim Area to Customs. Customs    All passengers must pass through Customs   after Passport Control.There is a choice of two channels.Green and Red.If you have nothing to declare,go through the Green Channel.If you are not sure about your Duty Free allowances  ,or if you have something to declare, go through the Red Channel.Information about Duty Free allowances can be found on special notice-boards in the Baggage Reclaim Area.You should study this information carefully whether you are going through the Red Channel or not.Please note that if you go through the Green Channel,you may be stopped and asked to open your luggage for inspection  . When a Chinese traveller is arriving at Heathrow Airport for a trip in London,he must   _  . A) fill out a landing card first B) walk through the Red Channel C) pass through Customs before Passport Control D) immediately get back his baggage after landing

As anyone who has tried to lose weight knows, realistic goal-setting generally produces the best results. That's partially because it appears people who set realistic goals actually work more efficiently, and exert more effort, to achieve those goals.  What are far less understood by scientists, however, are the potentially harmful effects of goal-setting. There has been surprisingly little research on how the practice may have contributed to the current economic crisis and unethical  behavior in general. "Goals are widely used and promoted as having really beneficial effects. And yet, the same motivation that can push people to exert more effort in a constructive way could also motivate people to be more likely to engage in unethical behaviors," says Maurice Schweitzer, an associate professor of operations and information management at Penn's Wharton School. His paper, titled "Goals Gone Wild: The Systematic Side Effects of Over-Prescribing Goal Setting," appears in the February issue of the Academy of Management Perspectives.  "It turns out there's no economic benefit to just having a goal-you just get a psychological benefit and that's quite motivating in itself," Schweitzer says. "But in many cases, goals have economic rewards that make them more powerful." A prime example Schweitzer and his colleagues give is the 2004 closing down of energy-trading titan Enron, where managers used financial rewards to motivate salesmen to meet specific sales goals. The problem, Schweitzer says, is the actual trades were not earning money. Other studies have shown that pressing employees with unrealistic goals can force them to lie, cheat or steal. Such was the case, Schweitzer says, in the early 1990s when Sears imposed a sales target on its auto repair staff. It resulted in employees overcharging for work and completing unnecessary repairs on a companywide basis. Schweitzer admits his research run against a very large body of literature that praises the many benefits of goal-setting. Edwin A. Locke, from the University... How did Sears' goal-setting affect its employees? A) They were forced to work more hours to increase their sales. B) They competed with one another to attract more customers. C) The improved their customer service on a companywide basis. D) They turned to unethical practice to meet their sales target.

Ques: Plants may not have eyes and ears,but they can recognize their siblings  ,and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete  . Canadian researchers published that sea rocket,a common seashore plant,can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil,they "play nice" and don't send out more roots to compete.However,the moment one of the plants is thrown in with strangers,it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil. After reading Dudley's study,Bais decided to find the method behind the sibling recognition.Working in his laboratory,Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments,young seedlings were exposed to liquid media containing the root secretions from siblings,from strangers,or only their own secretions.The length of the longest lateral   root was measured.The exposure of plants to the root secretions of strangers induced   greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter,because so much of their energy is directed at root growth.Because siblings aren't competing against each other,their roots are often much shallower  . Biedrzycki did the _ laboratory research,observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns."Arabidopsis roots are nearly translucent   when they are young and were also twisted when I removed them from plates,"Biedrzycki notes."This manuscript   is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions." The research also may have implications for the home gardener."Often we'll put plants in the ground next to each other and when they don't do well,we blame the...
