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.

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books. It would seem that there are three kinds of travel books. The first are those that give a personal, subjective (主观的) account of travels which the author has actually made himself, if they are informative and have a good index (索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective (客观的)description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called "a guide" to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way. Whatever kind of travel book you choose you must make sure that it does not describe everything as "wonderful", "excellent" or "magical". You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.This passage is about （）.A、how to travelB、how to buy travel booksC、how to read a travel bookD、travel books

单选题There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books. It would seem that there are three kinds of travel books. The first are those that give a personal, subjective (主观的) account of travels which the author has actually made himself, if they are informative and have a good index (索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective (客观的)description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called "a guide" to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way. Whatever kind of travel book you choose you must make sure that it does not describe everything as "wonderful", "excellent" or "magical". You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.The date of the publication must be noticed because （）.Athe world is changing and so are the places you are going to visitBthe price of the book is always changingCthe author of the book may be differentDthe contents of the book are always the same

单选题Passage1Do 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 travelers ，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 says.What can we conclude from the last paragraph？ATravel advices are not important.BTravel medicine is hard to be credible.CHow to prevent and treat disease can actually help travel medicine popularize.DPeople haven't realized the importance of travel medicine.
