An alcohol breath test (ABT) is often used by the police to find out whether a person is drunk while driving. In the United States, the legal blood alcohol limit is 0.08% for people aged 21 years or older, while people under 21 are not allowed to drive a car with any level of alcohol in their body. A “positive” test result, a result over the legal limit, allows the police to arrest the driver. However, many people who tested positive on the test have claimed that they only drank a “non-alcoholic” energy drink. Can one of these energy drinks really cause someone to test positive on an ABT? Researchers in Missouri set up an experiment to find out.
First, the amount of alcohol in 27 different popular energy drinks was measured. All but one had an alcohol level greater than 0.005%. In nine of the 27 drinks, the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT. They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27energy drinks, the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken. However, alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed. This shows that when the test is taken plays an important role in the test result. The sooner the test is conducted after the consumption of these drinks, the more likely a positive alcohol reading will be obtained.

Thousands of people living in the Chinese capital will celebrate the start of the Chinese New year by heading for the ski resorts (滑雪場). Never mind that Beijing’s dry weather seldom produces snow. It is cold enough in winter for snow-making machines to make a covering for the hills north to the capital. And the rapid growth of a pleasure-seeking middle class has formed the basis for this new craze(熱潮）.
Since Beijing’s first ski resort was opened ten years ago, the sport has enjoyed astonishing increase. There are now more than a dozen resorts. Clothes markets in the city have added bright colored ski suits to their winter collections. Mr. Wei, a manager of a newly-opened ski resort in Beijing, sees the growth of an industry that could soon lead Chinese to head for the ski resorts of Europe. In recent years ski resorts offering natural snow have opened in China. But many are in faraway areas of the country and can’t really match the equipment and services of some ski resorts in Europe.
Beijing’s skiing craze is partly a result of the recent increase in private cars. This has led to the growth of a leisure industry in the capital’s suburbs, which until the late-1990s were unreachable to ordinary people. According to Mr. Wei, about 40% of the visitors to his resort come in their own cars. The rest are bused in by schools, businesses or government offices.
The problem is making money. Starting ski resorts requires quite a lot of money: hiring land from the local government, preparing the hills, buying snow machines, making sure there are enough water and electricity to run them, and buying ski equipment for hiring out to customers.
The ski resort where Mr. Wei works cost nearly $4m to set up. And, as so often in China when someone comes up with a good idea, many others rush in and price wars break out. Beijing now offers some of the cheapest ski training classes in the world, though with most people rather new to the sport, expecting a few more doing the same job.
【小題1】What does this text mainly talk about?
| A．Convenience for skiers brought about by private cars. |
| B．Skiing as a new way of enjoying one’s spare time. |
| C．Things to be considered when starting a ski resort. |
| D．A sudden increase of ski training classes in Beijing. |
| A．To visit more ski areas. |
| B．To ski on natural snow. |
| C．For a large collection of ski suits. |
| D．For better services and equipment. |
| A．Difficulty in hiring land |
| B．Lack of business experience |
| C．Price wars with other ski resorts |
| D．Shortage of water and electricity |
