        One of the reasons I loved going up to the farm was the frogs.
        On hot summer evenings, big green frogs would   36   from the pond near the house, their voices like the twanging (弦声) of rubber bands. But the best   37   to see them was in the ditch (沟) beside the road, not the   38  . The ditch was home to the frogs called spring peepers.
        I learned this on the very first   39   I went looking for the frogs. Holding a   40   in front of me so I could see the way, I   41   across the driveway and over the grass toward the pond. When I got there,   42  , I didn't hear the sound I   43  . The high peeping (唧唧叫) noise seemed to come from further away. I turned around and followed the   44  .
        Kneeling by the ditch beside the road, I   45   the frogs were there. But I couldn't see them, because I didn't know where to   46  . I also had no idea what the spring peepers looked like — I only knew them by   47   and from a description in a book on pond life. Hearing their lively song, though, I started   48   with my torch.
        And there he was on some grass! A frog so   49   that he could have stood on a coin. His slimy skin was   50   in the pale light of my torch. He became   51  , probably frightened by the light.
       We looked at each other, his tiny   52   sack (袋) inflating and deflating (胀缩) like a balloon as he   53  . As I took my light off his body, he slowly started to   54   again. Wanting to disturb him and his many relatives   55  , I stood up and walked back to the driveway, listening to the calling of the frogs.  

第三部分：阅读理解（共20小题；每小题2分，满分40分）

        Are you tired of looking for love in all the usual places? Nowadays, millions of lonely singles are now going online instead. The World Wide Web is quickly becoming the world's most popular matchmaker. With so many singles online, dozens of dating sites like Yahoo Personals and Match.com are helping singles find that special someone. Around the world, from America to China, love is now very much online.
        Singles are flocking to the Internet mainly because their busy lifestyles leave them little time to look for a significant other. Using dating sites is quick and convenient. They can "meet" a lot more people online than they could by hanging out at a club. Besides, many singles say the regular dating scene has just led them from one bad experience to another and are ready to try something else. They also appreciate the first distance of online dating, which allows them to hide themselves until they are ready to meet someone face to face. Dating sites also make it easy to avoid someone you are not interested in. In the real world, however, ignoring someone you don't like can be embarrassing.
        Despite all the advantages, online dating also presents its own set of problems. People aren't always who they claim to be in their online profiles. For instance, someone who tells you he is "handsome, successful and single" might turn out to be homely, unemployed and married. Safety is another concern. You are just as likely to find a criminal online as you are Mr. or Miss Right.
        Even so, supporters of online dating see things in a positive way. In their opinion, singles can safely play the online dating game with a little common sense. Online dating experts recommend following a few safety tips:
        Guard your personal information. Never give out your personal information online. This includes your last name, phone number, home address and place of work.
        Watch for red flags. Do any of the people you are chatting with make disrespectful comments? Do they try to control you? Do they give false information about themselves? If so, forget them!
        Meet in a safe place. When meeting someone in person, choose a public location with other people around. Following these tips and you might be able to find the person of your dreams.

        America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect (影响) American society in many ways — education, medicine, and business. Quietly, the aging of America has led to a very different society — one in which people have a quite different idea of what kind of behavior (行为) is suitable (合适) at various ages.
        A person's age no longer tells you anything about his/her social position, marriage or health. There's no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn't as strong as it used to be. It doesn't surprise us to hear of a 29-year-old university president or a 35-year-old grandmother, or a 70-year-old man who has become a father for the first time. Public ideas are changing.
        Many people say, "I'm much younger than my mother — or my father — was at my age." No one says "Act your age" any more. We've stopped looking with surprise at older people who act in youthful ways.

        Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
        When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜) industry was destroyed by a virus five years ago, work began on creating genetically engineered trees.
        Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
        Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
        Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
        The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.
        So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes.
        However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
        "It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
        But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
        They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

        College graduation brings both the satisfaction of academic achievement and the expectation of a well-paid job.
        But for 6,000 graduates at San Jose State this year, there's uncertainty (不确定) as they enter one of the worst job markets in decades. Ryan Stewart has a freshly received degree in religious studies, but no job prospects (前景).
        "You look at everybody's parents and neighbors, and they are getting laid off and don't have jobs," said Stewart. "Then you look at the young people just coming into the workforce... it's just scary."
        When the class of 2003 entered college the future never looked brighter. But in the four years they've been here, the world outside has changed dramatically (巨大地).
        "Those were the exciting times, lots of opportunities, exploding offers, students getting top dollar with lot of benefits," said Chery Allmen-Vinnidge, of the San Jose State Career Center. "Times have changed now. It's a new market."
        Chery Allmen-Vinnidge ought to know. She runs the San Jose State Career Center, a sort of a crossroads between college and the real world. Allmen-Vinnidge says students who do find jobs after college have done their homework.
        "The typical graduate who does have a job offer started working on it two years ago. They've prepared themselves well during the summer. They've had several internships (实习)," she said.
        And they've majored in one of the few fields that are still hot—like chemical engineering, accounting, or nursing — where average starting salaries have actually increased over last year. Other popular fields (like information systems management, computer science, and political science) have seen big declines in starting salaries.
        Ryan Stewart (he had hoped to become a teacher) may just end up going back to school.
        "I'd like to teach college some day and that requires more schooling, which would be great in a dad economy." he said.
        To some students a degree may not be ticket to instant wealth. For now, they can only hope its value will increase over time.

        More than 60 years ago, the American Volunteer Group (AVG) came from America, thousands of miles from their homes, to help China fight against the Japanese and transport critical supplies during the Chinese People's War against Japanese Invasion. As their nickname suggests, these talented, energetic, adventurous young men were tigers in the sky, roaring their way to victory, and conquering the hearts and souls of the people in China and in the world.
        In the summer of 1938, Claie L. Chennault, a retired captain of the United States Army Air Crops, accepted an offer from Song Meiling, Madam Jiang Jieshi, and arrived in Southwest China's Kunming city to form a new Chinese Air Force to help China. In 1941, with secret support from the Roosevelt Administration, Chennault recruited (招收) American pilots and technicians under the private name of constitution. Later that year, over 200 members came to Chins. AVG fighter planes were painted with large shark teeth on the front of the plane. About the same time, they were given the nickname "Flying Tigers."
        During the war, The Tigers flew old and broken planes to transport needed materials from India to China across the Himalayas, protected the Myanmar road, and won air fight against the much better-equipped and larger-scaled Japanese air force in most areas of China. After the AVG was disbanded (解散) on July4,1942, the China Air Task Force of the United States Army Air Force officially took over air operations in China in early March of 1943,the 14th Air Force was activated under the command of Chennault and replaced the China Air Task Force. Chennault was promoted to Brigadier (准将) and later Major General as commander of the 14th Air Force.
        By the end of the war in 1945, the Flying Tigers shot down all together 2,600 planes, and destroyed or sank 44 warships. Most of the members of the Flying Tigers received rewards from the Chinese government. Over 10 pilots were awarded Aviation Squadron insignia from the American or Britain governments.
