Searching for airfares (飞机票价) often seems like a game that passengers are bound to lose.
Prices change from day to day, even minute to minute. Looking through multiple websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.
“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog.com.
Harriet Levy paid $179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $215. A few rows back, Ellis and Dianne Traub paid $317 each. There were at least 12 fares on the flight, ranging from $169 to $360.
There’s no reason for it, Harrison said.
Fares can fluctuate significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $755 to $1,143 from a Friday to Saturday in late April, then fell to $718 on Sunday.
The flight was one of a dozen the Associated Press followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.
There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:
? Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.
? Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are highest eight to 10 weeks and two to three weeks in advance.
? Make use of social media. Airlines are giving more benefits like exclusive (独家) sales to travelers who interact (互动) with them on Twitter and Facebook. Those specials are often gone within hours.
? The so-called discount (折扣) airlines – JetBlue, Air-Tran, Southwest and Frontier – adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.

Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.
Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
1.According to the author, attention should be paid to how driverless cars can __________.
A.help deal with transportation-related problems
B.provide better services to customers
C.cause damage to our environment
D.make some people lose jobs
2.As for driverless cars, what is the author’s major concern?
A.Safety. B.Side effects.
C.Affordability. D.Management.
3.What does the underlined word "fielded" in Paragraph 4 probably mean?
A.Employed. B.Replaced.
C.Shared. D.Reduced.
4.What is the author’s attitude to the future of self-driving cars?
A.Doubtful. B.Positive.
C.Disapproving. D.Sympathetic.

高三英语单项填空中等难度题查看答案及解析
We often seek food after focused mental activity,like preparing for an exam.Researchers guess that too much thinking consumes a lot of energy from the brain.So the brain,sensing that it may soon require more calories to keep going,apparently leads to bodily hunger,and even though there has been little physical movement,we eat.
The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.
Because the brain uses sugar and lactate as fuel,researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.
Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was.Afterward,they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted.At a later date,the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.
Next,half the students sat quietly for 15 minutes,before being given pizza.The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking,repeated five times.These students were then allowed to gorge on pizza,too.But by and large,they did not overeat.
When the researchers factored in(将……作为因素考虑)the calories burnt on running,they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.
The researchers do not know if the runners consumed extra calories at dinner.They also cannot tell whether other types of exercise would have the same effect as running,although the researchers say they suspect that if an activity causes someone to break into a sweat,it should also increase blood sugar and lactate,feeding the brain and weakening hungers call.
1.What do we learn from the first paragraph?
A. We eat for more physical movements.
B. A busy brain can make one hungry.
C. Energy from the brain can’t be used up.
D. An exam results in caloric consumption most.
2.What can a physical movement do?
A. Increase blood flow. B. Increase the amount of blood sugar.
C. Urge one to eat more. D. Make the brain tied.
3.What does the underlined phrase“gorge on”in paragraph 5 mean?
A. Eat. B. Purchase. C. Taste. D. Obtain.
4.What do the researchers want to know from the study?
A. Whether brain uses sugar and lactate as fuel.
B. Whether brain can be tired during exercise.
C. Whether exercise can reduce eating desire.
D. Whether exercise increases blood sugar.
