请阅读短文。Do who choose to go on exotic, far-flung holidays deserve free health advice before they travel? And even if they pay, who ensures that they get good, up-to-date information? Who, for that matter, should collect that information in the first place? For a variety of reasons, travel medicine in Britain is a responsibility nobody wants. As a result, many travellers go abroad prepared to avoid serious disease.Why is travel medicine so unloved? Partly there's an identity problem. Because it takes an interest in anything that impinges on the health of travellers, this emerging medical specialism invariably cuts across the traditional disciplines. It delves into everything from seasickness, jet lag and the hazards of camels to malaria and plague. But travel medicine has a more serious obstacle to overcome. Travel clinics are meant to tell people how to avoid ending up dead or in a hospital when they come home, but it is notoriously difficult to get anybody pay out money for keeping people healthy.Travel medicine has also been colonized by commercial interests; the vast majority of travel clinics in Britain are run by airlines or travel companies. And while travel concerns are happy to sell profitable injections, they may be less keen to spread bad news about travellers' diarrhea in Turkey, or to take time to spell out preventive measures travellers could take."The NHS finds it difficult to define travellers' health, says Ron Behrens, the only NHS consultant in travel and director of the travel clinic of the Hospital for Tropical Diseases in London." Should it come within the NHS or should it be paid for? It's Gary area, and opinion is spilt. No one seems to have any responsibility for defining its role, he says.To compound its low status in the medical hierarchy, travel medicine has to rely on statistics that are patchy at best. In most cases we just don't know how many Britons contract diseases when abroad. And even if a disease linked to travel there is rarely any information about where those afflicted went, what they are, how they behaved, or which vaccinations they had. This shortage of hard facts and figures makes it difficult to give detailed advice to people, information that might even save their lives.A recent leader in British Medical Journal argued. "Travel medicine will emerge as credible disciplines only if the risks encountered by travellers and the relative benefits of public health interventions are well defined in terms of their relative occurrence, distribution and control. Exactly how much money is wasted by poor travel advice. The real figure is anybody's guess, but it could easily- run into millions. Behrens gives one example. Britain spends more than 1 million each year just on cholera vaccines that often don't work and so give people a false sense of security."Information on the prevention and treatment of all forms of diarrhea would be a better priority, he salts.Which of the following statement is not the problem of travel medicine?查看材料A．Traditional disciplines are not enough for travel medicine.B．Travel medicine has been colonized by commercial interests.C．The statistics about travellers are hard to obtain.D．People spend much money on poor travel advice.

5 Ways to Focus Your Energy During a Work Crunch Work invariably ebbs and flows,cycling between steady states,where we feel more in control of the pace and workload,and peak periods,where the difficult work situation hits us hard.Unexpected setbacks or even vacations and holidays can create disorder and tension.Maintaining focus and managing energy levels become critical as tasks pile onto an already full load.When you're in your next work crunch,there are a few things you can do to focus and manage your energy more productively:41.When an acute period hits,it's easy to resist the fact that it's happening.We wish for things to be like they were last month,or we long for the pace we had during vacation.By not being present to the here and now,we drain our energy by pondering on the situation.In fact,physicists define resistance as"the degree to which a substance or device opposes the passage of an electrical current,causing energy loss."In the case of a diffcult work situation,the more you oppose what's happening,the more energy you lose.Acceptance does not mean giving in.On the contrary,it means acknowledging the reality of the situation with awareness so that you can take clear action.42.Acceptance is particularly difficult given the underlying emotions that an acute work crunch can bring.Negative thoughts often predominate.David Rock,director of the NeuroLeadership Institute,suggests that,rather than suppressing or denying an emotion,an effective cognitive technique is labeling,whereby you take a situation and put a label on your emotions.By assigning a word to what's happening,such as"pressure","guilt",or"worry",Rock's research shows.you can reduce the arousal of the limbic brain's fight-or-flight system and instead activate the prefrontal cortex,which is responsible for our executive funcLioning sk川s.43.A research out of the Universiry of Pittsburgh shows that anxiety directly impacts our cognitive functioning,especially those areas responsible for making souncl decisions.Don't fall into a victim mentality.believing there are no choices or that you don't have control.Instead,bring greater vigilance to assessing your priorities,making tough trade-offs,and incorporating self-care where you can.44.Other people can be a real energy drain-or gain-during work crunches and set-backs.Pause and consider how you can renegotiate deadlines,set tighter bounciaries,or ask for more support during this time.Many of us pride ourselves on not bothering others and being self-reliant.The.se are great qualities,but there are times when we need to ask for help.Ask your loved ones for more help on the home front.Share the weight of the accountability for projects with your colleagues by delegating or teaming up,versus doing it all on your own.45.Probably the toughest thing of all during a work crunch or setback is how easy it is to beat yourself up,especially when you aren't hitting your high standards for work,Annie McKee,author of the forthcoming book Howio Be Happy at,Work,says this:"If you really want to deal with stress,you've got to stop trying to be a hero and start caring for and about yourself."45选？A.Communicate with your colleagues and loved onesB.Stop thinking any unrealistic thingsC.Accept the situationD.Preserve your sense of choiceE.Control your negative emotionsF.Observe and label your underlying emotionsG.Practice self-compassion
Text 4 Eva Ullmann took her master's degree in 2002 0n the part that humour has to play in psychotherapy,and became hooked on the subject.In 2005 she founded the German Insiitute for Humour in Leipzig.It is dedicated to"the combination of seriousness and humour".She offers lectures,seminars and personal coaching to managers,from small firms tO such corporate giants as Deutsche Bank and Telekom.Her latest project is to help train medical studenis and doctors.There is nothing peculiarly German about humour training.It was John Morreall,an American,who showed that humour is a market segment in the ever-expanding American genre of self-help.In the past two decades,humour has gone global.An Intemational Humour Congress was held in Amsterdam in 2000.And yet Cermans know that the rest of the world considers them to be at a particular disadvantage.The issue is not comedy.of which Germany has plenty.The late Vicco von Biilow,alias Loriot,delighied the elite wiLh his mockery of German senousness and stiffness.Rhenish,Swabian and other regional flavours thrive-Gerhard Polt,a bad-tempered Bavarian,now 72,is a Shakespeare among Lhem.There is lowbrow talent ioo,including OLto Waalkes,a Frisian buffoon.Most of this,however,is as foreigners always suspected:more embanassing Lhan funny.Germans can often be observed laughing,loudly.And they try hard."They cannot produce good humour,but they can consume it,"says James Parsons,an English man teaching business English in Leipzig.He once rented a theatre and got students,including Mrs Ullmann,to act out Monty Python skits,which they did wiLh enthusiasm.The trouble,he says,is that whereas the English wait deadpan for the penny to drop,Germans invariably explain their punchline.At a deeper level,the problem has nothing to do with jokes.What is missing is the series of irony,overstatement and understatement in workaday conversations.Immigrants in Germany share soul-crushing stories of atlempting a non-literal turn of phrase,to evoke a hoffified expression in their Gennan friends and a detailed explanaiion of the literal meaning,followed by a retreat into awkward politeness.Irony is not on the curriculum in Mrs Ullmann's classes.Instead she focuses mostly on the bas-ics of humorous spontaneiLy and surprise.Demand is strong,she says.It is a typical German answer to a shortcoming:work harder at it.German comedy is mentioned to show that Germans_____A.are insensitive to humorB.have a good sense of humorC.always embarrass foreignersD.are not good at performance

问答题Practice 5 We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that they are among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among them, deriving their just power from the consent of the governed. That whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience has shown that mankind are more disposed to suffer, while evils are sufferable, than the right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. Such has been the patient sufferance of these Colonies; and such is now the necessity, which constrains them to alter their former systems of government. (Thomas Jefferso: The Declaration o f Independence)
问答题Practice 10 All social occasions in Sweden are regulated by rules and traditions. And these traditions are expressed in a specific ritual made up of formal bows, handshakes, and greetings. When a visitor enters a Swedish home, he is invariably received with a “Welcome”; when he leaves, his host will tell him “You will be welcome again.” These charming phrases are an indestructible part of Swedish social life and they give it an old-world flavor of good manners. Equally attractive is the Swedish acceptance of modern technological equipment. A traveler never needs to search for a telephone is Sweden: telephone booths are placed at regular intervals along the main streets and highways. And in church, for example, long benches are fitted with hearing aids for worshippers who may be hard of hearing. Swedish homes are among the best equipped in the world and travelers in Sweden find their journeys made easy by the use of the most efficient modern devices. The Swedes are an efficient and most capable people. This is their respect for their friends and acquaintances and especially for the visitor to their country. At whatever cost to themselves, they take care not to give another person the slightest degree of discomfort.

单选题Although many people would not believe it, the mosquito is actually the most dangerous animal in Africa. While the bite of the black mamba is invariably lethal when untreated, this dreaded snake kills only a few dozen people per year. Hippopotami, with their immense strength and foul dispositions, kill hundreds of people per year in rivers and lakes, but the mosquito is still more dangerous. Mosquitoes bite hundreds of millions of people in Africa every year, and they infect over a million each year with malaria, a disease that is often fatal. Which of the following questions would be most useful in evaluating the claim made above regarding the mosquito?ACould a person survive an attack by a black mamba if that person received prompt medical attention?BWhat criteria are used to determine which animal is the “most dangerous” animal?CCould the incidence of mosquito bites be decreased through the judicious use of pesticides and insect repellent?DDoes malaria kill more people per year in Africa than tuberculosis?EHow does the percentage of people who survive hippopotamus attacks in Africa each year compare with the percentage of people who survive mosquito bites?
问答题Culture is not just a matter of language; it involves the intellect, emotions, and—to me the most important of all—our senses. It is our instinctive responses that invariably reveal our cultural affiliations. Language is one obvious indicator; few people would shout out sudden pain and pleasure in a second language. But there are clear non-linguistic indicators as well, one of the most important being our preferences for food, particularly when feel unwell. All these can perhaps be summed up as “gut feelings”. Since these are responses uncamouflaged by our own or other people’s, manipulation and wishful thinking, they are very reliable.My two worlds not only sounded different, but also had different smells, textures and each moved to different rhythm. I was intrigued by the tangibility of that difference. It was like looking at two paintings, one a traditional Chinese landscapes, the other an impressionist work. Only I wasn’t just looking at them, I was living in a both of them simultaneously.
