    Worried about how many calories you will get in that piece of pizza, chocolate cake or bag of chips? A new iphone application Mealsnap may help. Users just need to take a picture of the meal with the phone, and it will give a calorie read-out almost immediately.
    Mealsnap was developed by DailyBurn, a health social network that focuses on helping its users lead healthier lifestyles. It has created several other health and diet-related iphone applications. The applications gives users a quick reply. To do that, it matches the taken picture to a databank containing the calorie information of nearly 500,000 kinds of food. Users then get the range of calories for the meal that is photographed.
    We started with something simple — an apple. A couple of minutes later the application replied that it was an apple and between 64 and 96 calories. More impressive was the reply we received after sending a photo of mixed salad bowl. Mealsnap replied that the bowl contained “yellow rice with corn, boiled eggs and beans” and that the food was between 532 and 798 calories.
    Mr. Smith, director of DailyBurn, said that usual calorie counting needed a long time, but that the application made it easier to know the calories in food. That’s why it is so popular among those who are trying hard to lose weight.
    In addition, Mealsnap can serve as a food diary. No need to write down what they’ve eaten, the photos will be stored. Then users can keep a visual log (记录). Mr. Smith said: “It’s like a food journal, but easier. All you do is to take the picture. The simple act of recording something can cause a psychological change that can help people on their health journey. Knowing the calorie range makes me think more about what I’m eating.

    A．help people have a healthy life

    MELBOURNE, Australia – A kangaroo frightened by a man walking his dog attacked the pair, throwing the pet underwater and hitting the owner in the stomach with its back legs. The Australian, Chris Rickard, was in stable condition Monday after the attack, which ended when the 49-year-old struck the kangaroo in the throat.
    Rickard said he was walking his blue dog, Rocky, on Sunday morning when they surprised a sleeping kangaroo in Arthur's Creek northeast of Melbourne. The dog chased the animal into a pond, when the kangaroo turned and knocked the pet underwater.
    When Rickard tried to pull his dog free, the kangaroo turned on him, attacking with its back legs and tearing a deep cut into his stomach and across his face.
    "I thought I might take action to drag the dog out from under his grasp, but I didn't expect him to actually attack me," Rickard, 49, told The Herald Sun newspaper. "It was a shock at the start because it was a kangaroo, about 5 feet high, they don't go around killing people."
    "I was stuck having to hold on to the dog with both hands because it was half drowned and I couldn't really see anything because the kangaroo just attacked me.”
    He added, "All I could do was just keep pushing for the bank and he was trying to push me under the water, so at that point I struck him in the throat and that made him back off a little bit.
    "I don't think I'll ever be able to watch kangaroo programs quite the same as I used to — it might bring back a couple of bad memories.”
    Kangaroos rarely attack people but will fight if they feel threatened.
    Dogs often chase kangaroos, which have been known to lead the pets into water and defend themselves there.
    Rickard said he ended the attack by hitting the kangaroo in the throat adding Rocky was "half-drowned" when he pulled him from the water.
    小题1:Rickard and his pet dog were attacked when _________.
    A．he was teasing a kangarooB．he was walking his dog
    C．swimming in the pondD．dragging his dog out from water
    小题2:In Australia, kangaroos ________.
    A．are only seen in zoos
    B．frequently attack people and pets
    C．get along rather peacefully with people
    D．can be found swimming in ponds
    小题3:The kangaroo attacked the man and his dog probably because ________.
    A．the man struck it in the throatB．the dog chased it
    C．the man wanted to drown itD．it wanted to drown the dog
    小题4:As a result of the attack, ________.
    A．the dog was drowned dead
    B．the kangaroo was killed
    C．kangaroos should be under stricter protection
    D．Rickard was left a deep impression

    Which is sillier: denying we ever went to the moon or trying to convince the true nonbelievers?
    Once upon a time – July 20, 1969, to be specific – two men got out of their little spaceship and wandered around on the moon for a while. Ten more men walked on the moon over the next three and a half years. The end.
    Unfortunately, not quite. A fair number of Americans think that this whole business of moon landings really is a fairy tale. They believe that the landings were a big hoax (骗局) staged in the Mojave Desert, to convince everyone that U.S. technology was the “bestest” in the whole wide world.
    Which is the harder thing to do: Send men to the moon or make believe we did? The fact is the physics behind sending people to the moon is simple. You can do it with computers whose entire memory capacities can now fit on chips the size of postage stamps and that cost about as much as, well, a postage stamp. I know you can because we did.
    However, last fall NASA considered spending $15,000 on a public-relations campaign to convince the unimpressed that Americans had in fact gone to the moon. That idea was mostly a reaction to a Fox television program, first aired in February 2001, that claimed to expose the hoax. The show’s creator is a publicity hound (猎狗) who has lived up to the name in more ways than one by hounding Buzz Aldrin, the second man on the moon. Mr. X (as I will call him, thereby denying him the joyous sight of his name in print) recently followed Buzz Aldrin around and called him “a thief, liar and coward” until the 72-year-old astronaut finally lost it and hit the 37-year-old Mr. X in the face.
    Anyway, NASA’s publicity campaign began to slow down. The nonbelievers took the campaign as NASA’s effort to hide something while the believers said that $15,000 to convince people that the world was round — I mean, that we had gone to the moon — was simply a waste of money. (Actually, the $15,000 was supposed to pay for an article by James E. Oberg, an astronomy writer who, with Aldrin, has contributed to Scientific American.)
    If NASA’s not paying Oberg, perhaps it could put the money to good use by hiring two big guys to drag Neil Armstrong out of the house. Armstrong is an extremely private man, but he is also the first man on the moon, so maybe he has a duty to be a bit more outspoken about the experience. Or NASA could just buy Aldrin a commemorate plaque (纪念匾) for his recent touch on the face of Mr. X.
    小题1:We can learn from Paragraphs 2 and 3 that some Americans believe _______.
    A．moon landings were invented
    B．U.S. technology was the best
    C．moon landing ended successfully
    D．the Mojave Desert was the launching base
    小题2:According to the writer, which of the following is to blame for the story about the hoax?
    A．NASA’s publicity campaign.B．The Fox television program.
    C．Buzz Aldrin.D．James E. Oberg.
    小题3:According to the writer, Mr. X _______.
    A．told a faithful story B．was not treated properly
    C．was a talented creator D．had a bad reputation
    小题4:The believers think that NASA’s publicity campaign is ________.
    A．proof to hide the truth
    B．stupid and unnecessary
    C．needed to convince the non-believers
    D．important to develop space technology
    小题5:The tone of the article is _______.
    A．angry B．conversationalC．humorousD．matter-of-fact

    A couple of years ago, before a trip to China, Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.
    “I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,” said Davis.
    Known as the “Iron Hammer” for her punishing spikes(扣球), Lang made it possible for China to dominate in the sport in the early 1980s. She was a key player on China’s 1984 Olympic gold medal winning team.
    When the US team arrived for the Olympics, Lang, 48, who is from Beijing, had to take a different route to avoid a crowd of reporters and fans.
    Then came the greatest moment to Lang：while the US team was playing in a packed gym, at least 8,000 Chinese fans unfurled an American flag.
    “That really says it all,” Davis said. “They look at her as an icon(偶像)．I’m sure it’s hard for them to see her coaching another country, but they love her so deeply that her success is their success.”
    The loyalty of the Chinese fans was tested on Friday, when China lost a match to the US.
    “It’s a pity that China lost the match, but I’m still glad that Lang Ping’s team won, since she is the pride of China’s volleyball,” said Liu Chengli, a spectator. “We also cheered for Lang’s victory.”
    Lang said she just tried to stay professional when the two teams meet. “It doesn’t matter if we play China or any other team. It’s the same.” Lang said.
    Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players, said a US volleyball player Lindsey Berg.
    “It’s such an honor to be here and play for our coach here in China,” she said. “The amount of support that the Chinese give to her and us has been tremendous. The whole event has been unbelievable.”
    小题1:What’s the passage mainly about?
    A．Staying professional.B．Cheering for the Iron Hammer.
    C．A match between China and the US.D．Lang Ping’s career as a coach.
    小题2:Lang Ping avoided meeting the reporters and fans probably because she ________.
    A．was afraid to be questioned about her strategy
    B．didn’t want to be paid much attention to
    C．disliked to be with her fans
    D．didn’t want to disturb public order
    小题3:What does the underlined word “unfurled” exactly mean?
    A．destroyed completely B．tore into pieces
    C．spread out to the windD．rolled up
    小题4:What does Lang Ping mean by saying “It doesn’t matter if we play China or any other team.”？
    A．American Volleyball Team will beat any team.
    B．Chinese Volleyball Team is the same as other teams.
    C．She just tried to stay professional.
    D．The results of each match will be the same.
    小题5:What impressed the US team players most?
    A．The tolerance of Chinese people.B．The popularity of volleyball in China.
    C．Lang Ping’s coaching skills.D．The loyalty for volleyball of the Chinese.

    When Debbie Parkhurst choked on a piece of apple at her Maryland home, her dog jumped in, landing hard on her chest and forcing the piece of apple to pop out of her throat. Debbie Parkhurst’s husband, Kevin, was at his job at a Wilmington, Del., chemical firm when she took a midday break from jewelry and bit into an apple. When the Keesling family of Indiana were about to be overcome by carbon monoxide(CO), their cat clawed(抓) at wife Cathy’s hair until she woke up and called for help.
    　　For their timely acts, Toby, a golden 2 1/2-year-old dog, and Winnie, a gray-eyed American shorthair, were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals.
    Neither Parkhurst nor Keesling could explain their pets’ timely heroics,though Parkhurst suggested it might have been guided by God intervention(干预). “That’s what our veterinarian(兽医) said,”she said. “He wasn’t making a joke; he’s very spiritual, and now I have to agree with him.”

    As the Keeslings recalled it, a gas-driven pump spread carbon monoxide through the house. By the time Winnie moved into rescue spot, the couple’s 14-year-old son, Michael, was already unconscious. “Winnie jumped on the bed and was clawing at me, with a kind of angry noise,” Cathy Keesling said. “When I woke up I felt like a T-bar had hit me across the head.”
    State police and officers responding to her 911 call said the family was only minutes from death, judging by the amount of poisonous gas in the house.

    The Beijing government has set out to recruit thousands of university graduates to work as junior officials in rural areas to both improve rural administration and ease the city’s employment problems.
    The government plans to recruit 3,000 university graduates this year,1,000 more than last year, to work as assistants to village heads or Party secretaries in suburban areas.
    People interested in jobs in Beijing’s rural villages and townships can submit applications to the Beijing Municipal Personnel Bureau or online at www. Bjbys. com from February 1 through March 15.
    “We hope university graduates will seize this opportunity to use their knowledge in rural villages and to start their careers,” Sun Zhenyu, deputy director of Beijing Personnel Bureau, told Xinhua News Agency.

    The ministry predicts that 4. 95 million students will graduate from universities across the country this year, 820,000 more than last year. About 1.4 million of them are unlikely to find jobs when they graduate.
    In Beijing, a record 200,000 people are expected to graduate from university this year. Less than half of them are expected to be offered jobs, according to the personnel bureau.

    WASHINGTON — It is announced Friday that White House visitor records will be opened up on a regular basis for the first time in modern history, providing the public an unusually detailed look at who gets the opportunity to help shape American policy at the highest levels.
    “Americans have a right to know whose voices are being heard in the policymaking process,” the president said in a written statement issued by the White House while he vacationed with his family at Camp David.

About 70,000 to 100,000 people visit the White House each month, and the records will include tourists as well as people conducting business.
    The White House pointed out several exceptions to the policy: “purely personal guests” of the Obama family; those cases in which the disclosure(透露) of visitors’ names “would threaten national safety interests”; and those who come for “particularly sensitive meetings,” like candidates for a Supreme Court nomination(提名). Officials said only a “small number” will fit in the latter category（类别）, and their names would eventually be disclosed after they are no longer secret, like after a nomination is publicly announced. Moreover, they said, the number of undisclosed visitors will be disclosed, to make clear how few they are.

    BEIJING, March, 17th --The Japanese automaker Toyota will recall some 4,400 units of FJ Cruiser cars in China over seat belt flaws, China's consumer quality watchdog said Saturday.
    The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) said on its website that Toyota China will recall these imported cars produced between December 2007 and March 2013.
    Toyota is busy working on the solution to the flaw and will release improvement methods before April 15, according to the administration.
    This marks Toyota's second recalling this year after the auto giant announced in January that it would recall 22,869 units of Lexus IS cars in China due to wiper arm problem.

    Also on Saturday, the AQSIQ said in a statement on its website that its research has basically confirmed the German automaker Volkswagen's direct shift gearbox (DSG) transmission has defects which may cause engine power failures and urged Volkswagen to recall defective cars after China Central Television (CCTV) exposed Volkswagen's gearbox defect on Friday.
