Most people who travel long distances complain of jetlag. Jetlag makes business travelers less productive and more prone（1）making mistakes. It is actually caused by （2） of your "body clock"——a small cluster of brain cells that controls the timing of biological （3） , The body clock is designed for a （4）rhythm of daylight and darkness, so that it is thrown out of balance when it （5） daylight and darkness at the "wrong" times in a new time zone. The — （6） of jetlag often persist for days （7）the internal body clock slowly adjusts to the new time zone.Now a new anti-jetlag system is （8）that is based on proven （9）pioneering scientific research. Dr. Martin Moore Erie has （10） a practical strategy to adjust the body clock much sooner to the new time zone （11） controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates （12）of the discomfort of jetlag.A successful time zone shift depends on knowing the exact time to either （13） or avoids bright light. Exposure to light at the wrong time can actually make jetlag worse. The proper schedule （14） light exposure depends a great deal on （15） travel plans. Data on a specific flight itinerary and the individual’s sleep （16） are used to produce a Trip Guide with （17） on exactly when to be exposed to bright light.When the Trip Guide calls （18） bright light, you should spend time outdoors if possible. If it is dark outside, or the weather is bad, （19） you are on a plane, you can use a special light device to provide the necessary light （20） for a range of activities such as reading, watching TV or working.

Environmentalists may get off on terrifying climate change, but most people just turn away. “If it was really so bad, they’d do something,” says one colleague. The human tendency to convince yourself that everything is OK, because no one else is worried, is deeply seated.Our tendency to shrug off responsibility seems to hold true even when we ourselves are in danger. John Darley and Bibb Latane asked a series of college students to sit in a room and fill out a questionnaire. When smoke started to pour into the room through a vent, the others, all actors, ignored it and went on writing calmly. Ninety percent of subjects copied the actors, even when the smoke became so thick that they could barely see and were coughing. But subjects who were alone in the room, under the same conditions, almost all reported the smoke as an emergency. That is an astonishing finding — that the inaction of other people can make us underestimate threats to our own safety.In the past few weeks we have been told, by reputable sources, that the oceans are warming faster than anyone predicted. That species are becoming extinct a hundred times faster than fossils record. That we are approaching tipping points that may make climate change irreversible. This stuff makes me feel pretty desperate. I would think that other people would worry too. But then I go to the office, and to friends’ houses, and no one mentions it. Nor do the politicians. Despite the noise from green groups, we look for get-out clauses. We blame other countries or big corporations. The part of our brain that is programmed to imitate dominates the part cued to self-preservation — especially when the threats are complex and long-term. Could we send the herd in the other direction? Maybe. Ten years after Darley and Latane’s smoke experiment, another professor Arthur Beaman showed its films to his students. He explained the psychology. And in future those students were, apparently, almost twice as likely as others to react to help other people.In January I counted a Toyota Prius hybrid car on almost every one of the rich streets in a part of London just east of my house. Yesterday I did another count. They seemed to have increased to two or three. That is the power of imitation, for people who can afford it. But how do you get other people to imitate behavior that is less visible: buying less, traveling less or changing their electricity supplier? The answers must surely lie in social etiquette. If we are programmed to act like lemmings, then we must give some people incentives to break out and publicize their activities.The smoke is coming up through the vent. If enough people start talking about the smoke, perhaps others will start to see it too. And if enough people act, the rest may follow. For that, it seems, is human nature.1.It can be inferred from the first two paragraphs that people tend to （ ）.2.In face of environmental degradation, most people are （ ）.3.Professor Arthur Beaman's experiment shows that （ ）.4.The author suggests that in order to counter climate change,（ ）.
