    To switch or not to switch, that is the question.Google’s announcement of its Nexus One smartphone（智能手机） happened over a week ago and I’m still receiving lots of e-mails from readers asking the same question: Should they give up their iPhone for the Nexus One?
    Some people with iPhones, disappointed by American Telephone&Telegraph’s inadequate service and the high monthly cost, are wondering if they have really got something to replace it.Does the Nexus One offer the functions that Apple has led them to expect?
    I’m on the fence myself, even though I never thought I’d be interested in anything but the iPhone.From my experience using the Nexus One, and from talking to people who have made the change, it’s not necessarily about the differences between the iPhone and the Nexus One.The phones are extremely similar in design and general feel.Instead, the decision can be made based on the software（软件） services you use on your desktop.
    My friend Chad Dickerson received a pre-launch Nexus One from Google three weeks ago.He said Google’s phone feels connected to certain services on the Web in a way the iPhone doesn’t.“Compared to the iPhone, the Google phone feels like it’s part of the Internet to me,” he said.“If you live in a Google world, you have that world in your pocket in a way that’s cleaner and more connected than the iPhone.”
    Personally, the phones work perfectly with their own software, but both of them don’t make an effort to play well with other services.

    1. 1.

      Why are some iPhone users expecting a new type of phone?

      1. A.
        Because their old ones are out of date.
      2. B.
        Because they accept Google’s announcement.
      3. C.
        Because of the limited service and high cost.
      4. D.
        Because of the terrible software they can use..
    2. 2.

      What’s the author’s attitude towards the new phones in the third paragraph?

      1. A.
        Negative
      2. B.
        Neutral
      3. C.
        Indifferent

    Two elderly women in my community died "full of years,"which means both died from the normal wearing out of the body after a long and full life. Their homes happened to be near each other, so I paid visits to the two families.
    The son of one of the deceased(已故的) women said to me,"If only I had sent my mother to Florida and got her out of this cold ,she would be alive today. "The son of the other deceased woman said, "If only I hadn't insisted on my mother's going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. "
    When things don't turn out as we would like them to, it is very likely for us to think that if we had done things differently, the story would have had a happier ending. Any time there is a death, the survivors will feel guilty.
    There seem to be two elements in our readiness to feel guilty. The first is our pressing need to believe that the world makes sense and that there is a cause for every effect and a reason for everything that happens. That leads us to try to find the patterns and connections.
    The second element is the notion(观念)that we are the cause of what happens, especially the bad things that happen. Psychologists trace this feeling back to our childhood. A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. The world works for him. When he cries, someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow the notion that our wishes cause things to happen.

    1. 1.

      What is said about the two deceased elderly women?

      1. A.
        They lived long and died after a natural life.
      2. B.
        They died due to lack of care by family members.
      3. C.
        They died of the tiredness after the long plane ride.
      4. D.
        They weren't quite used to the change in weather.
    2. 2.

      People feel guilty for the deaths of their beloved ones because_______.

      1. A.
        they believe that they were responsible
      2. B.
        they do not know the natural course of events
      3. C.
        they couldn't find a better way to express their grief
      4. D.
        they didn't know things often turn out in the opposite direction
    3. 3.

      The underlined sentence "the world makes sense" probably means that_______.

      1. A.
        we have to be sensible so as to understand the world
      2. B.
        everything in the world is pre-determined
      3. C.
        there's an explanation for everything in the world
      4. D.
        the world can be interpreted in different ways
    4. 4.

      People have been made to believe since babyhood that_______.

      1. A.
        every story should have a happy ending
      2. B.
        their wishes are the cause of everything that happens
      3. C.
        life and death is an unsolved mystery

        everybody should obey their wills without question

    On August 26, 1999, New York City experienced a torrential downpour. The merciless rain caused the streets to flood. New York City' s subway system came to a screeching stop as the subway stations were drowned in water. Unfortunately, this happened during the morning rush hour.
    Many people who were going to work were trapped and forced to go home. Some battled with fellow New Yorkers to hail a cab or to get on a bus. Still others braved the storm, walking miles to get to work.
    I happened to be one of the people on their way to work that morning. I went from subway line to subway line only to find that most service had stopped. After running around like crazy and making my way through crowds of people, I finally found a subway line that was operating. Unfortunately, there were so many people waiting to board the subway that I could not even get down the stairs to the platform. Determined to get to work, I decided to take the train uptown several stops and then switch back to the downtown train. It was annoyance, but it paid off. However, the train got more packed at each stop. People pushed and shoved. I was constantly hit with elbows and bags. Finally, after what seemed like an eternity (no end),the train reached my stop.
    But the journey was not over yet. I would still have to walk several blocks to get to my office. When I finally got to work, I was completely soaked and left a puddle of water everywhere I sat. I was also exhausted (tired out)and discouraged from my commute.
    My co-workers and I spent most of the day drying off. When 5:00 rolled around,I was ready to go home. I was about to log off my computer when I received an email from Garth, my Deputy Director:
    I would like to thank all those who made the effort and eventually reported to work. It is always reassuring, at times like these, when employees so clearly show their devotion to their jobs. Thank you.
    His email was short,but I learned more from that brief message than I ever did from a textbook. The email taught me that a few words of appreciation can make a big difference.The rainstorm and the transit troubles had made me miserable.But Garth's words immediately invigorated me and put a smile back on my face.As a matter of fact,his email made the whole subway painful experience all worthwhile.
    August 26,1999 may have been one of the darkest days in New York City history,but it was one of the brightest days in my life thanks to Garth.

    Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics（抗生素）or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible.
    Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food.
    They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets.
    However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic.
    Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus（共同看法）is that, in the short term, organic farming is less damaging for the following reasons:
    ● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife.
    ● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals.        
    ● Organic farms are more energy efficient and produce less waste.
    Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food.     
    However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive.

    1. 1.

      Early consumers knew what food was “organic” by _______.

      1. A.
        firsthand experience                                    
      2. B.
        the “certified organic” label tag
      3. C.
        its packaging                                                     
      4. D.
        examining its organic certification
    2. 2.

      We can infer that _______.

      1. A.
        in America, organic food can only be bought in small stores or farmers’ markets
      2. B.
        organic food is also available in large supermarkets at present
      3. C.
        organic food is produced by large-scale farms
      4. D.
        organic food is often beautifully packaged
    3. 3.

      According to the passage, organic food is considered as _______.     

      1. A.
        junk food             
      2. B.
        delicious snacks              
      3. C.
        green food     
      4. D.
        conventional food
    4. 4.

      What is the main idea of the last paragraph?

      1. A.
        The benefits of organic food.                              
      2. B.
        The cost of organic food.
      3. C.
        The disadvantages of organic food.                  
      4. D.
        Organic food and conventional food.
    5. 5.

      Which of the following statements does NOT support the view that organic farming is more environment-friendly?

      1. A.
        Organic food is generally thought to be more nutritious.
      2. B.
        Organic farms are more energy efficient and produce less waste.
      3. C.
        Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals.

    Galaxy saw a man and a woman who communicated with the sign language at the train station when she was on the way home one evening. She noticed that the woman asked the mon for the direction. He told her that he did not know. Galaxy decided to help them. She had learned the sign language when she served as a volunteer in the deaf and mute（聋哑）school. Then she showed the woman the direction and left her email address to them in case they needed her help later.
    She received an email from that man the next day. Kazrim was his name. Galaxy replied his mail sincerely. They both started chatting online soon after and began seeing each other. Although they only communicated with the sign language, it never bothered her.
    Galaxy was fond of him gradually. Obviously, Kazrim was the same too. He presented Galaxy with a bunch of sunflowers and asked her sincerely, “Are you willing to be my girlfriend?” Galaxy was pleasantly surprised. She requested him to give her some time to persuade her parents.
    As she had expected, her parents were very angry after they had learned of their love story. Galaxy explained, “Kazrim is an excellent and a very optimistic person. He has a very positive attitude towards life and work. He cares for others always. He is 100％ better than the normal. Moreover, the mute is still a human. He should possess a perfect and wonderful love. ”
    Her parents asked to see him, then. The very worried Galaxy took Kazrim home a few days later. When they were on the train, Kazrim told her, ‘‘I’m going to tell your parents I’ll be looking after you well with all my life!” Galaxy was deeply moved.
    As soon as they had entered the house, Galaxy introduced him to her parents. She said, ‘‘This is Kazrim.” Just right after her speech, an unbelievable thing happened. Kazrim threw the gift away and held her in his arms tightly.
    He said, “YOU CAN TALK?” It was the same question that Galaxy wanted to ask, too.

    Age has its special advantage in America. And one of the more impressive of them is the senior citizen discount. Anyone who has reached a certain age—in some cases as low as 55-is automatically entitled to plenty of price reductions at nearly every level of commercial life. Eligibility（资格）is determined not by one’s need but by the date on one’s birth certificate. Practically the discounts have become a routine part of many businesses-as common as color televisions in motel rooms and free coffee on airliners.
    People with gray hair often are given the discounts without even asking for them；yet, millions of Americans above age 60 are healthy and solvent（有支付能力的）. Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous（同义的）. Perhaps that once was true, but today, to be sure, there is economic variety within the elderly, and most of them aren’t poor.
    It is impossible to determine the effect of the discounts on individual companies. For many firms, they are a stimulus to income. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they directly annoy some politicians and scholars who consider it a coming conflict between the generations.
    Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another point. Supported by laws and court decisions, more and more older Americans are refusing the retirement dinner in favor of staying on the job-thereby lessening employment and promotion opportunities for younger workers. Far from a kind of charity they once were, senior citizen discounts have become a powerful economic privilege（特权）to a group with millions of members who don’t need them.
    It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enrich the myth that older people can’t take care of themselves and need special treatment；and they threaten the creation of a new myth, that the elderly ale ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the heart of the very thing older Americans are fighting against-discrimination by age.

    1. 1.

      We learn from the first paragraph that   .

      1. A.
        offering senior citizen discounts has become routine commercial practice
      2. B.
        senior citizen discounts have enabled many old people to live a good life
      3. C.
        giving senior citizen discounts has increased the market for the elderly
      4. D.
        senior citizens have to show their birth certificates to get a discount
    2. 2.

      The reason to give the senior citizen discount is that   .

      1. A.
        the elderly need humane help from society
      2. B.
        businesses should do something for society in return
      3. C.
        old people are entitled to special treatment for their contribution to society
      4. D.
        the senior discounts can make up for the lack of the Social Security system
    3. 3.

      What does the author think of the Social Security system?

      1. A.
        It encourages elderly people to retire in time.
      2. B.
        It opens up broad career chances for young people.
      3. C.
        It benefits the old at the expense of the young.
      4. D.
        It should be strengthened by laws and court decisions.
    4. 4.

      What does the author mainly argue in the passage?

      1. A.
        Senior citizens should fight hard against age discrimination.
      2. B.
        The elderly are selfish and taking senior discounts for granted.
      3. C.
        Senior citizen discounts may well be a type of age discrimination.
      4. D.
        Discount should be given to the economic needs of senior citizens.

    Picking tomatoes
    For as long as I can remember, Grandma’s plentiful tomato garden has been a sign of summer’s end. Each September, just as the decreased heat of the sun suggests cooler days, Grandma requests my help in her tomato garden. She convinces me she cannot pick tomatoes without my youthful eyes and quick mind. She says we need to examine each tomato and agree on its readiness for picking. While Grandma’s request for my help in the tomato garden is always the same, her desire for my help seems to increase each year.
    Grandma has eyes for finding even the tomatoes hidden by undergrowth and other tomatoes. I, however, just turn circles looking for the ones I think Grandma will like. I spot what looks like a ripe tomato, head in its direction, and then get sidetracked by another that appears to be equally ripe. I usually end up watching Grandma and trying to stay out of her way, which seems the only way my eyes and mind ale useful.
    There we are, lost in the tomato vines（藤）. Grandma’s eyes are always knowing, and they are no different in the vegetable garden. From afar she spots what looks like a ripe tomato. As she walks toward the garden, she evaluates the tomato for a second time. but from a different angle. I already know it will end up in the basket with the pile of others Grandma has carefully chosen. However, Grandma acts as if she needs a final look to be sure. She calls me to her side, kneels beside the vine while enjoying the warmth of the fading sunlight on her face, and grasps the tomato in her hand. She turns each round, red ball toward the sunlight before disconnecting it from thevine with a half-hearted smile.

    Are you a new rider who simply wants to travel outdoors on the weekend，weather permitting？Do you intend to test yourself on the rough roads，every day，rain or shine？Or are you going to use your new mountain bike to ride to and from school or work？Be honest about your intentions，and you’re more than half way toward choosing the right mountain bike for you.
    Visit your local bike shops.
    Any good bike shop will stock a wide range of quality mountain bikes in all price points and sizes. Your local bike shops will carry more than one brand of bicycle. Not only will they sell you a mountain bike that suits your needs，but they will service what they sell. Visit at least a few shops. You’ll get one that satisfies you right away.
    Don’t be bashful.
    Tell your salesperson how you intend to use your new mountain bike，and how much you are willing to spend. Your salesperson will show you a selection of models and brands accordingly. He or she will also help you determine the right size for you. You may ask more without any sense of shyness.
    Take a test ride.
    All good bike shops let customers take test rides. There’s a good reason for this beyond “try­before­you­buy” salesmanship. Since you already know your price range and find the right size，you now have to find out which brand you ride best. They want you to be happy with your purchase. After only a few test rides from more than one bike shop，the right mountain bike will choose you.

    Agnes Miller was one of the earliest leaders of the Women’s Liberation Movement in the United States. She was born on a farm in Missouri in 1892. Strangely enough she had a very happy life as a child. She was the only daughter and the youngest child of five. Her parents and her brothers always treated her as their favorite.
    In 1896 the family moved to Chicago. Three years later they moved back to St. Louis where Agnes spent the rest of her childhood. She enjoyed her years in school and was an excellent student of mathematics. She also was quite skillful as a painter.

    I clearly remember my mom telling me to drink milk every day—one glass in the morning and another at night. I also remember loving it while my sister thought quite the opposite—she would surreptitiously pour her milk into the sink or water the plants with it! I guess I should thank my mom for making us drink a lot of milk, so rich in calcium(钙), during those important years.
    Today, calcium shortage is one of the main concerns of women in their 30s or even early 20s. The great fear is that when we reach our 50s or 60s, osteoprosis(骨质疏松症)will set in. That is why you can see a lot of advertisements for products supposedly containing a lot of calcium.
    Because calcium is not that easy to acquire from the food we normally eat, busy women these days should take calcium supplements(补充物). There are a lot of different forms of these---calcium carbonate(碳酸钙)，oyster(牡蛎)shell or bone-meal-based calcium supplements.
    You have to be careful when choosing which kind to take. This is because calcium is not easily absorbed by the body. So the fact that you are taking supplements doesn’t mean that the body is actually benefiting from them. Different supplements may have different instructions on dosage(剂量)and manner of intake. You can ask your doctor to help you determine which supplement is the best for your needs.
