    Moving flight times from night to day could reduce air travel's contributions to global warming, a new study suggests. Scheduling more (lay time flights may reduce the influence of contrails ——the visible lines of white steam that many planes leave behind them in the sky.

    The role of contrails in climate change is still being studied, but some scientists believe they contribute to the greenhouse effect by trapping heat in the atmosphere.

    Nicola Stuber, first author of the study, suggests that contrails' overall impact on climate change is almost as big as that of aircraft? s carbon dioxide emissions (排放)over a hundred-year period. Aircraft are believed to be responsible for 2-3% of human carbon dioxide emissions. Like other high, thin clouds, contrails reflect sunlight back into space and cool the planet. However, they also trap energy in the atmosphere and increase the warming effect.

    Stuber and other scientists believe that the effect of the contrails is big. "On average, the green-house effect controls the effects of contrails, said Stuber, a meteorologist at England's University of Reading." The warming effect is far greater for contrails left by night flights," Stuber added. "The cooling effect only happens (luring the day when the sun is up. During the night the greenhouse warming is no longer balanced and that is why the contribution of night-flight is so large."

    Most commercial airline traffic occurs during daylight hours. For example, only one in four United Kingdom flights is a night flight, but those flights create some 60% of the warming created by contrails, the study reports.

(1)、How do contrails increase the greenhouse effect?
A、They give off heat. B、They absorb daylight. C、They trap heat in the atmosphere. D、They reflect sunlight back into space.
(2)、What does the underlined word "they" in Paragraph 3 refer to?
A、carbon dioxide emissions B、contrails C、flights D、thin clouds
(3)、What did Stuber explain about the contrails in Paragraph 4?
A、What their function is. B、How they cool the Earth. C、Why they create big warming at night. D、How big their effect is.
(4)、What can be a suitable title for the text?
A、Airlines Should Schedule Flights B、Night Flights Face a New Challenge C、Airplane Contributes Most to Global Warming D、More Day Flights May Reduce Global Warming

    “Success begins with belief and ends with doubt.”—Larina Kase

    I remember reading through a book and the author was writing about being a reverse paranoid. In that particular section he mentions how he has a belief that the world he's living in is out to give him everything he absolutely wants and desires.

    There are times when I think to myself,“Wow,the world is out to get me and make me miserable.” Then I thought,why can't I believe that the world is out to make me a better conversationalist. Then I started adapting to the belief of the reverse paranoia.

    When I started talking to people,I truly believed that I was the most interesting person in the room. I believed that everything I said added value to the conversation. I believed that people stayed behind and chatted with me because they found me charismatic.

    As a matter of fact, for about five months I wrote down on my bathroom mirror the following affirmation:“People love me and respect me. It is a privilege to talk to me. People find me interesting and charming and always want to get to know me better!”

    I would say the affirmation after I brushed my teeth. And I would continue to say it until I felt completely great about myself. There were days that I just wouldn't feel like saying it,because it would feel like a lie to me. But that's the trouble,like the quote says,success ends when there's doubt. And that's why I continued until I had no doubt in my mind.

    Then strange things happened,I noticed that people did find me more interesting,and that I gained more confidence in talking with people. I was more assertive(坚定自信的) at work. I was able to control politics and gossip at work to minimal levels,and became a much better manager,and developed better customer relations to the point that sales were up by 20% compared to the year before,on my best month sales were up by 39%,and this was a year that a recession was happening.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

    Eat your vegetables.Wash your hands.Always say“please”and“thank you”.We are full of advice for our children, but when it comes to money,we often have little to say.As a result,our children may grow up with clean hands and good manners,but without any idea how to manage their money.

    Here are some basics that will help guide them their entire lives:

    Show them the future.If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month,by the time she's 65,she would have $980,983!

    Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history,but they must be used responsibly,which means paying off your debt in time.Explain to your children that when you buy something using a credit card,you can easily end up paying two or three times what you would have paid if you used cash.

    Teach patience.Suppose your child wants a new bicycle that costs $150.Rather than paying the cash,give him some regular pocket money and explain that by putting aside,say,$15 each week,he will be able to buy it for himself in only ten weeks.

    Provide incentive(激励机制).Tell your children the importance of saving."For every dollar he or she agrees to save and invest rather than spend,you agree to add another dollar to the pot,"says Cathy Pareto,expert in money planning.

    Explain your values.Values and money are deeply intertwined(纠缠在一起),says Eilleen Gallo,co-author of The Financially Intelligent Parent.When your child demands that you buy something,explain why you really don't want to buy it.“You might say,‘I'd rather save that money for your education,'”advises Gallo.Every time you spend or don't spend money,you have a chance to share your values.

    The sharing economy, represented by companies like Airbnb or Uber, is the latest fashion craze. But many supporters have overlooked the reality that this new business model is largely based on escaping regulations and breaking the law.

    Airbnb is an Internet-based service that allows people to rent out spare rooms to strangers for short stays. Uber is an Internet taxi service that allows thousands of people to answer ride requests with their own cars. There are hundreds of other such services.

    The good thing about the sharing economy is that it promotes the use of underused resources. Millions of people have houses or apartments with empty rooms, and Airbnb allows them to profit from these rooms while allowing guests a place to stay at prices that are often far less than those charged by hotels. Uber offers prices that are competitive with standard taxi prices and their drivers are often much quicker and more trustworthy.

    But the downside of the sharing economy has gotten much less attention. Most cities and states both tax and regulate hotels, and the tourists who stay in hotels are usually an important source of tax income. But many of Airbnb's customers are not paying the taxes required under the law.

    Airbnb can also raise issues of safety for its customers and trouble for hosts' neighbors. Hotels are regularly inspected to ensure that they are not fire traps and that they don't form other risks for visitors. Airbnb hosts face no such inspections.

    Since Airbnb is allowing people to escape taxes and regulations, the company is simply promoting thefts. Others in the economy will lose by bearing an additional tax burden or being forced to live next to an apartment unit with a never-ending series of noisy visitors.

    The same story may apply with Uber. Uber is currently in disputes over whether its cars meet the safety and insurance requirements imposed on standard taxis. Also, if Uber and related services flood the market, they could harm all taxi drivers' ability to earn a minimum wage.

    This downside of the sharing needs to be taken seriously, but that doesn't mean the current tax and regulatory structure is perfect.

On an autumn afternoon, a remote sheep farm in southern Greenland is quiet. The silence is abruptly broken when dozens of sheep come thundering across the hills overlooking the farm. Walking after them are Lars Nielsen and his 37-year-old son Kunuk Nielsen.

The Nielsen family has owned and run the farm since 1972. Kunuk says the summers now are longer than when he was a child and that drought has become a problem. The fields are not so green as those in the old days. He has to buy hay (草料) from European countries.

The effects of a warming climate are obvious on the land. While he intends to struggle on, his older brother Pilu has chosen a different path.

Pilu, 40, lives in Qaqortoq in the south of Greenland -- a town of about 3,000 people. Ten years ago, he got his helicopter pilot's license and is now part owner of a small company called Sermeq Helicopters. It caters to construction and telecommunication workers and an increasing number of foreign tourists.

Pilu says he loves his family's sheep farm. But he saw that warming temperatures were making remote areas of Greenland more accessible and wanted to look for other opportunities. His company's most popular tours include a visit to Greenland's glaciers.

The warming temperatures are also affecting traditional ways of life, particularly hunting. The sea ice is changing; it's becoming less so that hunting on ice becomes more difficult. When there's no sea ice, it's difficult to use dog sledges (雪橇), and the whole culture around having dogs and dog sledges and doing traditional hunting on the ice is sort of diminishing.

Besides, many Greenlanders, like Pilu, are leaving the countryside for towns and the capital city Nuuk, where opportunities are greater. A report found that Nuuk's share of Greenland's population grew from 17.2% in 1977 to 29.2% in 2014. If there were enough houses in Nuuk, the share would even be bigger.
