单选题People travel for a lot of reasons. Some tourists go to see battlefields or religious shrines. Others are looking for culture, or simply want to have their pictures taken in front of famous places. But most European tourists are looking for a sunny beach to lie on. (77) Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year in the rain. This is the reason why the Mediterranean has always attracted them. Every summer, more than 25 million people travel to Mediterranean resorts and beaches for their vacation. They all come for the same reason: sun! The huge crowds mean lots of money for the economies of Mediterranean countries. Italy's 30,000 hotels are booked solid every summer. And 13 million people camp out on French beaches, parks and roadsides. Spain's long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly, or one tourist for every person living in Spain. (78) But there are signs that the area is getting more tourists than it can handle. The Mediterranean is already one of the most polluted seas on earth. And with increased tourism, it's getting worse. The French can't figure out what to do with all the garbage left by campers around St. Tropez. And in many places, swimming is dangerous because of pollution. None of this, however, is spoiling anyone's fun. The Mediterranean gets more popular every year with tourists. Obviously, they don't go there for clean water and solitude. They tolerate traffic jams and seem to like crowded beaches. They don't even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as the sun shines, it's still better than sitting in the cold rain in Berlin, London, or Oslo.

单选题On-the-job smoking is a hot issue for both smokers and non-smokers, and many managers now see smoking as a productivity(生产力) problem. Although some people question whether smoking really affects one"s productivity, it has, in fact, been proven that a smoker costs a company more than a non-smoker. According to Professor William Weis, a smoking employee costs his or her employer about $5,700 more a year than a never-smoker. These costs include medical care, lost earnings and insurance. And absence due to smoking breaks is one of the productivity problems, yet it accounts for a great deal of employer costs. When the issue of smoking at the workplace is discussed, perhaps the most important problem is the health risk that smoking causes to both smokers and never-smokers. It has long been proven that smoking is linked to lung cancer. Now many health experts warn that passive smoking can cause lung cancer and other illnesses in healthy never-smokers. Passive smoking can be defined as exposure to second-hand tobacco smoke in enclosed areas. Anyone who has been with smokers indeed knows that their smoke can cause eye irritation (刺激), coughing, headaches and throat soreness. While eye irritation may seem a small thing to some smokers, it nevertheless is a problem that occurs every workday in offices and break-rooms and can lead to greater health problems. Employees who do not smoke should not be subjected(遭受) to the risks of passive smoking and need to be able to work in a safe environment. Surgeon General Koop states that the right of the smoker stops at the point where his or her smoking increases the disease risk of those occupying the same environment.
