The old man walked slowly into the restaurant. With head tilted, and shoulders bent forward he leaned on his trusty stick with each unhurried step. His torn cloth jacket, patched trousers, worn out shoes, and warm personality made him stand out from the usual Saturday morning breakfast crowd. He stopped, turned with his whole body, and winked at a little girl seated by the door. She flashed a big smile right back at him.
A young waitress named Mary watched him walk toward a table by the window. She ran over to him, and said, "Here, Sir. Let me give you a hand with that chair." She pulled the chair away from the table. Steadying him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she moved the table up close to him, and leaned his stick against the table where he could reach it.
In a soft, clear voice he said, "Thank you, Miss. And bless you for your kind gestures."
"You're welcome, Sir." She replied. "And my name is Mary. I'll be back in a moment, and if you need anything at all in the mean time, just wave at me!"
After he had finished a hearty meal, Mary brought him the change from his ticket. He left it on the table. She helped him and walked with him to the front door. Holding the door open for him, she said, "Come back and see us, Sir!" He turned and nodded a thank-you. "You are very kind." he said softly, smiling.
When Mary went to clean his table, she almost fainted. Under his plate she found a business card, and a note scribbled on a napkin. Under the napkin was a one-hundred-dollar bill.
The note on the napkin read, "Dear Mary, I respect you very much, and you respect yourself too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you."
The man she had waited on was the owner of the restaurant where she worked. This was the first time that she, or any of his employees had ever seen him in person.

Experts say that agriculture provides fourteen percent of the world's greenhouse gas emissions each year．The gases released include carbon dioxide, a major cause of global warming．
Twenty-one nations around the world recently joined forces to better understand and prevent greenhouse gas emissions from farms．The Global Research Alliance on Agricultural Greenhouse Gases was launched at the United Nations conference on climate change．The meeting took place in Copenhagen, Denmark last month．
Agricultural experts blame a number of farm activities for producing greenhouse gases．For example, animal waste and cattle digestive systems release methane （甲烷，沼气） gas．Fertilized soil and the burning of crop waste also release harmful gases into the air．Experts say some methods of farming ?turning the soil to prepare for planting ?also release harmful carbon dioxide．
An official of the European Commission's Directorate General for Research says agricultural greenhouse gas emissions can be cut．Maive Rute suggests feeding animals a diet designed to reduce emissions．
The new agricultural research group says protecting against global warming is only part of its purpose．It says the world also needs to develop better farming methods to feed growing populations in poor countries．
United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural greenhouse gas emissions and increase food production at the same time．This is why the alliance is important for combining resources and finding new ones．
The United States Department of Agriculture will increase spending on farm emissions research by ninety million dollars over the next four years．The total will reach one hundred thirty million dollars．The U．S．D．A．will share the research with other countries in the Global Research Alliance on Agricultural Greenhouse Gases and support researchers from developing countries that belong to the alliance．Money from the Borlaug Fellowship program will let the researchers study agricultural climate change with American scientists．
Mister Vilsack said that just as climate change has no borders, there should be no borders for research．
72．In Paragraph 4, Maive Rute recommends _____．
A．increasing food production
B．changing cattle digestive systems
C．developing better fanning methods
D．giving animals the food meant to produce fewer emissions
73．The underlined word "alliance" in Paragraph 6 probably means _____．

D．inform readers of the major cause of global warming

Compared to adults, children seem to be moving constantly．So it's no surprise that most parents who are quizzed about their child's physical activity level describe their children as fairly active．But a new study of nearly 2,000 British school children suggests that many parents overestimate the amount of physical activity their children are really getting．
The researchers equipped 1,892 British school children, ages 9 and 10, with accelerometers that measure all physical activity during a given time period．The research, known as the Speedy study collected the exercise data from children at 92 schools in Norfolk, England, between April and July 2007．
A child was regarded inactive if he or she recorded less than an hour a day of physical activity．Although the majority of children studied were getting enough physical activity, a sizable minority of children were not．Overall, 39 percent of girls and 18 percent of boys studied were getting less than an hour of physical activity each day．
But if you asked the parents of the inactive children to describe their child's activity level, the vast majority—80 percent—described their children as fairly or very physically active, according to the findings published in the American Journal of Preventive Medicine．Interestingly, the children themselves had more awareness about their lack of physical activity．Overall, 40 percent of children overestimated their physical activity．
But it wasn't the parents of overweight children who were most likely to guess wrong about physical activity levels．The parents who were most out of touch about their child's physical fitness were more likely to have children who were slim．Parents of girls were also more likely to overestimate physical activity．The researchers noted that parents should be educated about the importance of physical activity for children even if the child is not overweight．
"Parents of slim children appear to assume that their children are adequately active," the study authors reported．"Increasing awareness regarding health benefits of physical activity beyond weight control might help have a correct idea of physical activity levels and encourage behavior change．"
69．According to the Speedy study, what kind of children can be judged physically inactive?
A．Slim children．
B．Children with less than an hour a day of physical activity．
C．Overweight children．
D．Children out of touch with their parents for a long time．
70．What does the writer probably mean by saying "a sizable minority of children were not" in Paragraph 3?
A．The amount of children's physical activity is far from the writer's satisfaction．
B．Only a small number of children were not getting enough physical activity．
C．A small number of children didn't overestimate their physical activity．
D．The minority of children were not studied at all．
71．The passage is intended to ____．
A．encourage parents to fairly judge their child's physical activity levels
B．persuade parents to keep an eye on their children's weight
C．urge children to wear accelerometers during exercise
D．advise parents to keep in touch with their children

Last year was the year of the travel deal, with resorts and
airlines practically begging for bookings, and many travelers
finding bargain airfares and hotel rooms as a result．Now the
economy looks as if it might be on a slight rebound．So now is
the perfect time to review your booking strategy（策略）．
Here are 4 simple steps you can take to help cut your travel costs in 2010．
1．Find the Cheapest Dates to Fly
ITASoftware．com, which provides the technological backbone for many airfare shopping sites, allows users to scan an entire month's fares for the least expensive rate．（Log in as a "guest" and click on "month-long search．"） In January, the 28th and 30th were the cheapest dates to fly nonstop to London from New York （$536） for a week's vacation, according to a recent search．The next best was Saturday, Jan．23, at $640．To book the ticket, users must go to another site．Kayak．com has a flexible-dates option （registration is required）and a calendar that shows the best fares found by other Kayak users in the last 48 hours．Bing Travel, the Microsoft search engine, offers a similar option, found under "plan trips," about halfway down the page．
2．Consider Nearby Airports
A recent Web search showed nonstop flights from Los Angeles International Airport to Miami International from $299 round trip on American in early January．But flying into Fort Lauderdale, roughly 30 miles north of Miami, was $219 on Virgin America, an $80 saving．
3．Go Against the Grain
If possible, avoid popular travel dates like holidays and spring break because airlines have begun to charge anywhere from $10 to $30 extra at those times．Farecompare．com offers a handy breakdown of the new fees by date, airline and amount．Early-morning and late-night flights may also be cheaper depending on the route．
4．Make Yourself at Home
For a 6 to 12 percent booking fee, AirBnB/com connects budget travelers with locals who are offering a place to bed down．The Times's Frugal Traveler, Matt Gross, described it as "a cross between CouchSurfing．com and the vacation rentals section of Craigslist．" There were more than 2,000 listings in a recent search for New York including a futon （床垫） in a one-bedroom near Gramercy Park （$65） and a bedroom with private bath and separate entrance in Hell's Kitchen （$150）．
65．According to the first paragraph, ____．
A．the economy in 2010 is surely getting better
B．2009 saw a sharp decrease in travel fees
C．the booking strategies can be put away in 2010
D．in 2009, airlines begged the travelers to buy more travel guides
66．If you want to book a ticket, you may log on to _____．
A．ITASoftware．com B．CouchSurfing．com
C．AirBnB．com D．Kayak．com
67．What does "Go Against the Grain" probably mean in the passage?
A．Going travelling in the off-season．
B．Going travelling without taking any grain．
C．Going travelling during holidays and spring break．
D．Going travelling without meals served on early-morning and late-night flights．
68．The passage is most probably taken from ____．
A．a book review B．a magazine
C．a website D．a story book

For many employers, Facebook, MySpace and other social networking sites are already a threat （威胁） that cut into productivity．Now they have something else to worry about—the games hosted by these sites．
This new type of social gaming is called "asynchronous" gaming and allows people to play with their friends without having to be online at the same time．The low-intensity （低强度） engagement has made games such as FarmVille, Cafe World and Pet Society popular among employees who often log on during office hours．
"What we are seeing is that more and more people and organizations are recognizing the productivity lost so probably more chief information officers are blocking Facebook applications," Rebecca Wettemann of Nucleus Research said．
Boston-based Nucleus Research, which conducted a recent study into the effects of social networking sites on productivity, said nearly half of office employees in the United States access social networking sites at work, which leads to an average loss of 1．5 percent of total office productivity．
Facebook, which has 350 million users, says at least 20 percent of its members play games online．Sebastien de Halleux, CEO and co-founder of online game creator Playfish, said Asia is growing at a faster pace than other regions．"We had no idea that it would spread so fast．．．when we had 100,000 users after one month, we thought it was the biggest success ever．Now with 60 million users we think this is only the beginning of something much bigger," he added．
Zynga's FarmVille, the best known game with over 70 million active users to date, allows players to own a virtual farm where they can grow crops and raise animals．
While companies try to limit access to social networking sites, not everyone sees the games as harmful．
61．We can learn that Pet Society is a game _____．
A．popular among employers B．without having to be online
C．merely played during office hours D．that can be played online at a different time
62．It can be inferred from the passage that ____．
A．Playfish is owned by Sebastien and Rebecca
B．Playfish has over 70 million active users to date
C．Asia will be the largest potential market for Playfish
D．Playing online games loses 1．5 percent of total office productivity
63．The best title of the passage would be ____．
A．Social Network Gaming B．New Threat to Productivity
C．Social Networking Sites D．Latest Survey on Productivity
64．What would most probably be discussed next after the last paragraph?
A．Opinions in favor of online games．
B．Measures to limit access to social networking sites．
C．Suggestions on how to improve productivity．
D．More examples about the bad effects of online games．
