[单选题] A decade ago, the idea that the planet was warming up as a result of human activity was largely theoretical. We knew that since the Industrial Revolution began in the 18th century, factories and power plants and automobiles and farms have been loading the atmosphere with heat-trapping gases, including carbon dioxide and methane (甲烷). But evidence that the climate was actually getting hotter was still murky. Not anymore. As an.authoritative report issued a few weeks ago by the United Nations-sponsored Intergovemmental Panel on Climate Change makes plain, the trend toward a warmer world has unquestionably begun. Worldwide temperatures have climbed more than 0.5℃ over the past century, and the 1990s were the hottest decade on record. After analyzing data going back at least two decades on everything from air and ocean temperatures to the spread and retreat of wildlife, the IPCC asserts that this slow but steady warming has had an impact on no fewer than 420 physical processes and animals and plant species in all countries. Glaciers, including the legendary snows of Kilimanjaro, are disappearing from mountaintops around the globe. Coral reefs are dying off as the seas get too warm for comfort. Drought is the norm in parts of Asian and Africa. El Nino (厄尔尼诺) events, which trigger devastating weather in the eastern Pacific, are more frequent. The Arctic permafrost (永久冻土带) is starting to melt. Lakes and rivers in colder climates are freezing later and thawing earlier each year. Plants and animals are shifting their ranges pole-ward and to higher altitudes, and migration patterns for animals as diverse as polar bears, butterflies and beluga whales are being disrupted.

According to the United Nations-sponsored Intergovemmental Panel on Climate Change,________.

A. it is doubtful that worldwide global warming has begun
B. people should not show concern about global warming
C. it is obvious that the world has started getting warmer and warmer
D. we should carry out more research to prove the effects of global warming

[单选题] Millions of Americans lie awake at night counting sheep, or have a stiff drink or pop an allergy pill, hoping it will make them drowsy. But experts agree all that self-medicating is a bad idea, and the causes of chronic insomnia remain mysterious. Almost a third of adults have trouble sleeping, and about 10 percent have symptoms of daytime impairment that signal true insomnia. Sufferers readily cite the resulting problems: walking around in a fog, as memory and other cognitive functions slowly. Dozing off at the wheel or at work. Depression. Lack of energy. But for all the complaints, scientists know surprisingly little about what causes chronic insomnia, its health consequences and how best to treat it, a panel of specialists brought together by the National Institutes of Health concluded Wednesday. Two things are clear, the panel found: Chronic insomnia is a major public health problem. And too many people are using unproven therapies, even while there are a few treatments that do work. Among the panel's findings: Cognitive / behavioral therapy-a psychology-based treatment that trains people to reduce anxiety and take other sleep-promoting steps-is very effective, and doesn't cause side effects. But it can be hard to find health providers trained in the techniques. Insomniacs should check with board-certified sleep specialists and psychologists. Newer prescription sleep pills called Sonata, Ambien and Lunesta work without many of the side-effect concerns of older agents known as benzodiazepines (苯二氮类镇静药). One study of Lunesta showed effectiveness with six months of use, but more research on long-term use of all three is needed, as chronic msomma can linger for years. The most commonly used treatments are alcohol and over-the-counter sedating antihistamines (抗组．胺剂) like Benadryl. Alcohol use actually disrupts quality sleep, and antihistamines can cause lingering daytime sedation and other cognitive problems. The most common prescription insomnia medicine is an older, sedating antidepressant called trazodone, even though there's no good evidence that it offers more than a two-week benefit, and it comes with side effects.

One of most effective ways to deal with choric insomma is ________.

A. to have a stiff drink
B. to pop an allergy pill
C. to sleep and get up early
D. cognitive / behavioral therapy
