    From New Delhi to Beijing，commuters（通勤者）spend a lot of time stuck in traffic．In the United States，Los Angeles（L．A．）and San Francisco tie for second place（并列第二）for having the worst traffic problems．Washington，D．C．is in first place with the worst traffic，according to the Texas A＆M Transportation Institute．
    In L．A．．drivers spend sixty－one hours every year stuck in traffic．These drivers know all too well how bad the traffic can be．Professor Cyrus Shahabi also knows about traffic jams．He said，“It’s a prison of cars．There are too many cars，you can’t move around a lot．I live more than 65 kilometers from my office at the University of Southern California．in L．A．．I’m always late even with the help of a navigation（导航）system．I thought it would be appropriate to do something to solve it．”
    Therefore，he and PhD student Ugur Demiryurek decided to develop an app for that．The ClearPath app claims to do what other navigation systems cannot．Professor Shahabi says his program uses historical data to predict traffic conditions even before the driver leaves the house．
    ClearPath uses two and a half years worth of traffic data from 9，000 sensors（传感器）on the roads of L．A．．It also collects information on accidents．
    Professor Shahabi says his system does more than just respond to current traffic conditions．With ClearPath，he says，a driver can enter what time he wants to leave on a specific time and date，and ClearPath will give the fastest route．It looks at the entire road network，including surface streets as well as highways，before the driver hits the road．
    Ugur Demiryurek says they will launch the free ClearPath app for roads in L．A．in two months．In a year，he and Professor Shahabi hope to have ClearPath available nationwide and overseas once they can collect traffic data from other cities．
    “I thought always that L．A．had the worst traffic，but now I know that Shanghai，Beijing，Seoul，Tokyo，believe it or not，Singapore，Hong Kong definitely are examples that can immediately use this．”
    小题1:The ClearPath app can mainly be used to __________．
    A．predict traffic conditionsB．kill the boring time

    England will play Italy, Uruguay and Costa Rica in a tough Group D at the 2014 World Cup in Brazil. Roy Hodgson's men open their campaign against Italy in the Amazonian city of Manaus on 15 June in the only World Cup game which kicks off at 02:00 BST. England take on Uruguay on 19 June and play Costa Rica five days later.
    Hosts Brazil are in Group A with Cameroon, Mexico and Croatia while the World Cup holders Spain open with a repeat of the 2010 final against Netherlands.
    England will have to travel 1,777 miles from their chosen base in Rio for their first match in the tropical heat of Manaus.
    Earlier this week Hodgson described Manaus as "the place to avoid" because of the climate—temperatures reach 30C and humidity is about 80%—although after the draw the England boss took comfort from the fact his team face a fellow European side.
    "The conditions in the north will be tough, so we will both be in same boat," he said. "If we'd had three games up in the north, it would have been difficult."
    Following Hodgson's initial comments, the mayor of Manaus, Arthur Virgilio, said England would not be welcome in the city.
    England takes on two-time champions Uruguay in Sao Paulo and they play Costa Rica in Belo Horizonte—both cities are within 225 miles of their base.
    England have never previously beaten Italy or Uruguay at a major tournament(锦标赛), while they have never faced Costa Rica.
    Uruguay, who reached the semi-finals in 2010, and Italy, who knocked Hodgson's men out of Euro 2012, are ranked sixth and seventh respectively in the Fifa rankings while Costa Rica are 31st in the world - 18 places below England.
    小题1:When and where will England play its third group stage match?
    A．On 24 June; in Manaus
    B．On 24 June; in Belo Horizonte
    C．On 19 June; in Manaus
    D．On 19 June; in Sao Paulo
    小题2:Which of the following can England take comfort from?
    A．The place where its first match in the group stage is held.
    B．The distance from its base to where its first match is held.
    C．The fact that two of its group stage games are not in the north.
    D．The fact that it is 7 places below Uruguay in the Fifa rankings.
    小题3:Which of the following is true according to the news report?  
    A．Roy Hodgson is the coach of Brazil national football team.
    B．Netherlands took the second place in the last World Cup.
    C．The mayor of Manaus is a fan of the British soccer team.
    D．England has never played against Uruguay in the history.

    April 11, 2003 12:44 a. m. PST, Associated Press
    The respiratory(呼吸系统) virus known as SARS has appeared to spread in the United States only to family members of health workers with close contact to a sick person.
    On Thursday, the head of the Centers for Disease Control and Prevention said there might be a case of severe acute respiratory syndrome（综合症） spreading through the workplace.
    Dr. Julie Gerberding said a suspected SARS virus patient who became ill after traveling to Asia might have infected a co-worker in Florida, which made her “very worried”.
    So far, a dozen people—nine family members and three health workers—were infected after coming into close contact with the person with SARS. The rest of the 166 suspected American cases have something to do with people who were infected while traveling in Asia.
    In the Gainesville, Fla. area, a 47-year-old woman was believed to have been infected at work by a 60-year-old woman who was the nation’s first suspected SARS case, said Tom Belcuore, director of the Alachua County health department.
    Since the World Health Organization announced a worldwide warning last month about SARS, the United States has started infection control in hospitals and among families of suspected cases.
    Florida officials said a school in Okaloosa County went through a cleaning after a 6-year-old boy suspected of having SARS appeared at school with slight symptoms. “Health officials are watching the boys’ contacts at school to make sure no one else is infected,” said Rob Hayes, health department spokesman, “The boy may have been infected from a family member,” Hayes said, “We immediately became aware of it and had the child sent home. He’s staying at home with his family until 10 days after symptoms disappear.”
    The researchers guessed that the virus might have come from animals. However, the scientists have not ruled out the possibility that some other microbe might also help make SARS more serious or easier to catch.
    小题1:The best title for this text is _______.
    A．A Worldwide Warning
    B．Suspected SARS Cases
    C．What Is SARS
    D．Possible Spread of SARS in the USA
    小题2:The writer wrote this text mainly to _______.
    A．discuss the danger of SARS
    B．report research result about SARS
    C．inform people of the spread of SARS
    D．explain to the readers what SARS is
    小题3:How many cases of suspected SARS are there in the U.S.A. according to the text?
    A. 166.             B.178.              C. 12.              D. 181.

    To make our digestive (消化的) system work well, we should avoid doing some things after having a meal, for example, drinking water. It is true that a person should drink 8 glasses of water every day to stay healthy. However, drinking water right after eating or even during a meal may disrupt (扰乱) digestion. It might affect the natural levels of acid and bile (酸和胆汁) that are necessary for proper digestion. What’s more, drinking cold water after eating might slow down digestion. So try to avoid drinking water at least an hour after a meal, and avoid drinking it while eating.
    Though walking after eating is healthy, doing it immediately after a meal is not. Doing so will make it difficult for the digestive system to take in nutrients (营养) from the food. Besides, the blood will flow towards other parts of the body, like legs, hands, etc., which will make the digestive tract not have enough amount of blood flow that is needed for proper digestion. So we should wait for at least 2 hours after eating, and then begin exercising.
    Sleeping should also be avoided right after eating. This is because going to bed right after a meal will lead to improper digestion. What’s more, such a habit will also make you put on a lot of weight. Therefore, wait for an hour or two, and then go to sleep.
    Many of us have the habit of drinking tea just after lunch or dinner, which is really unhealthy. The tea leaves contain a large amount of acid which prevents the protein in the food from digesting. The best time to drink tea is at least one hour after eating.
    Eating fruits right after a meal may fill the stomach with air and cause discomfort. They will also take time to reach the digestive tract, disturbing the entire process of digestion. To protect your stomach from digestive problems, eat fruits before or after 1-2 hours of a meal.
    In a word, if you avoid doing all the above things after eating, you will surely make your digestion easy, and you will be less likely to have digestive problems.

    A photographer takes a picture of the Chinese bronze rat head and rabbit head sculptures display on the preview of the auction（拍卖） of Yves Saint Laurent and Pierre Berge’s art collection at the Grand Palais in Paris, France, Feb, 21, 2009. Chinese lawyers have asked the French court to stop auction house Christie’s putting two bronze relics（文物）looted (掠夺)from China
    under the hammer, lawyers said Friday.
    A Paris court on Monday ruled against stopping the sale of two
    looted Chinese bronze sculptures which come up for auction at
    Christie’s on Wednesday. Under the ruling of the Tribunal de Grande
    Instance in Paris, the plaintiff（起诉人）, the Association for the

    Ren Xiaohong, a lawyer for APCAE, told Xinhua that it was “of great significance” to file the lawsuit. “We hope to arouse public attention in Europe on the fate of numerous Chinese works stolen in the past, to help keep those relics well protected and collected,” Ren said.
    The Qing Dynasty（1644—1911）relics, the heads of a bronze rabbit and a rat, were among an original set of 12 bronze animal heads that were once decorated at the imperial summer resort Yuanmingyuan. They were looted when the palace was burnt down by Anglo-French allied forces during the Second Opium War in 1860.
    The pair became part of a collection of the late fashion designer Yves Saint Laurent. They have been put up for auction by his partner, Pierre Berge. The two items are expected to fetch between 16 million and 20 million euros.
    So far, five of the 12 bronze animal heads have been returned to China, while the whereabouts of five others are unknown.

    A．The 12 bronze animal heads have been put up for auction.
    B．The 2 bronze animal heads haven’t been returned to China.
    C．The 12 bronze animal heads were used as imperial decoration.
    D．Yuanmingyuan was once burnt down by Anglo-French allied forces.
