　　     Bats are the only flying mammals(哺乳动物)in the world. They can't see very well, but they have no trouble flying on the darkest nights and catching the insects (昆虫) that they eat. How do bats manage to fly by radar (雷达)?　　 The bats' radar system (系统) works the same way as the one the ships and planes use, like the radio signals that bounce (反射) back when they hit an object.　　As a bat flies through the air, he sends out of series (系列) of sounds, thirty to sixty per second. The sound can't be heard by the　　 human ear. If the sounds hit an object, these returned sound signals tell the bat where the object is.　　　　 　　The bats' radar system is very good.Tests have been made with　　 bats in a crowded room. Blind in the light, the bats could fly about the room and never touch any object.

Money, or the lack of it, changes everything, and that includes how people will be working out in 2010.

In these belt-tightening times  1  , cost-conscious workouts（锻炼）at home and at the gym topped the list of fitness trends for this year in a survey, followed  2   by shorter, more time-efficient regimens, such as  3   boot camp（强力集中训练） and circuit training.

"People are looking  4   for ways to accomplish as much as possible with as little  5   time and money as necessary," said Cedric X. Bryant, chief science officer of the American Council on Exercise (ACE), which conducted the online poll of fitness professionals.

"Last year money was on the list but this  6   year the majority of the respondents put  7   it as one of the top," he added.

Bryant said some 600 ACE-certified fitness  8   professionals responded to the annual poll  9  , which the non-profit organization has been conducting for a decade.

Other money-saving measures  10  , such as the shift from personal training sessions to small group training  11   classes and in-home workouts  12   using smaller, more portable equipment, also made the list.

"Personal trainers are seeing they've got to respond to market needs  13  . Working with two to four clients at a  14   time they can charge less  15   but still get their hourly fee," Bryant said.

Boot-camp workouts and circuit training, both of which burn  16   calories while building strength and endurance（持久性）, will be among the most popular trends in 2010, as time-constrained（受压制的） consumers  17   seek shorter, more intense activities.

One bright spot is the rise of exergaming-type systems, like Nintendo's Wii Sports, Wii Fit and the PC-based Dancetown. Bryant says the fitness-based video games are turning up  18   in health clubs and senior centers.

Functional training workouts, which are geared to improving the quality of life and the ability to perform everyday tasks, will remain strong  19  , and the use of computerized tracking and online training and scheduling tools will increase  20   in the coming year.

Four out of ten women who diet end up heavier than when they started watching their waistline, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight.
Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said, ‘In the UK 61.4 percent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.’
The “Food, Body, Mind” report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they were currently on a diet and one in five women said they were on a continuous diet.
It found the most common triggers to start dieting was seeing their reflection in the mirror,  preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half.
However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers’ polishing off（吃光）their children's leftovers was another common cause of weight gain.

Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart.
“I have two kids in college, and I want to say ‘come home,’ but at the same time I want to provide them with a good education,” says Jacobs.
The Jacobs family did work out a solution: They asked and received more aid from the schools, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program. They will each graduate with $20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators(管理者) expect to hear more families like the Jacobs. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition（学费）continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%. Student borrowing has more than doubled in the last decade,
“If we go on this way for another 25years, we won’t have an affordable system of higher education,” says Patrick M. Callan, president of the center. “The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt.”
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.
【小题1】How did the Jacobs manage to solve their problem?

A．They asked their kids to come home.

B．They borrowed $20,000 from the school.

C．They encouraged their twin sons to do part-time jobs.

D．They got help from the school and the federal government.

【小题2】 Financial aid administrators believe that ______________.

A．more families will face the same problem as the Jacobs

B．the government will receive more letters of complaint

C．college tuition fees will double soon

D．America’s unemployment will fall

【小题3】What can we learn about the middle class families from the text?

A．They blamed the government for the tuition increase.

B．Their income remained steady in the last decade.

C．They will try their best to send kids to college.

D．Their debts will be paid off within 25 years.

【小题4】According to the last paragraph, the government will       ____.

A．provide most students will scholarships

B．dismiss some financial aid administrators

C．stop the companies from making student loans

D．go on providing financial support for college students
