    16．Up to now，the Hope Project ______ thousands of children who would otherwise have died．（　　）
    A．would saveB．savesC．had savedD．has saved

    分析 到目前为止，希望工程已经拯救了成千上万个不然会死去的孩子．

    解答 答案：D
    根据句中的时间状语"Up to now"（到目前为止），此处表示过去的动作"save"（拯救）持续到了现在，所以这里应使用现在完成时；故选D．

    点评 本题考查了现在完成时除了强调"影响性"之外的另一用法；即表示过去发生的动作持续到了现在；做本题时，需要熟练掌握现在完成时的意义及用法．

    7．On countless mornings over the past year，I stood with my son，James，in our driveway，watching our neighbor hurry off to kindergarten．My wife and I wanted to give James the best  education，but that meant we'd have to change our jobs and spend less time with our kid．I asked myself，"Would this trade-off be worth it？"When I look at the research on child development，I think it might not．Where our kids go to school might matter less than most American parents think．
        Social scientists have long tried to determine why some children grow up to be successful．In a 2001 study，Greg Duncan，a professor of education at the University of California，measured the influence that the people in a child's life have on how well the child does in school．Duncan and his team found almost no relationship between how students did on the test and whom they sat beside in class，whom they hung out with after school and who lived in their block．The only meaningful link they found was between siblings （兄弟姐妹） and twins in particular．
         For a long time，scholars thought that a family's income heavily affected how well kids did   in life．But that might not be the case．When Susan Mayer at the University of Chicago looked at the relationship between family income and lifetime achievement，she ran a series of experiments to measure it，finding such outcomes weren't caused by income．She argued that the things that make a difference are relatively inexpensive：the number of books a kid has or how often his family goes to museums．
        Lareau，another scholar began one of the most in-depth observations of American parenting．He concluded that success is much more related to the amount of time parents spend with their children．He said"Many parents I interviewed are anxious about their children's futures．But they have exaggerated（夸大） the sense of the risks involved if they don't give their children'the best'of everything．"
        So at last，we decided to leave things as it were．More time with our kid is the best we can provide．
    25．The first paragraph is intended toA
        A．introduce the topic of the passage
        B．confirm the result of a research
        C．stress the importance of good education
        D．support a research on child development
    26．From the passage we know that most American parentsC．
        A．spend a lot of time with their children
        B．like to buy a variety of books for their children
        C．think children's achievement largely depends on schools
        D．believe their income cannot afford children's education
    27．Who believes children's brothers and sisters may influence their academic performance？B
        A．Lareau．         B．Greg Duncan．    C．Susan Mayer．    D．James．
    28．Which of the following can be the best title of the passage？A
        A．Parents'time matters to children's future．
        B．School education determines children's future．
        C．Family income counts to children's achievements．
        D．Less education means more risks for children's success．

    4．Google Glass，a wearable computer，will not go on sale for many months．But the resistance is already under way．The glasses-like device，which allows users to access the Internet，take photos and shoot videos，has been banned by a bar in Seattle，because according to the bar'owner，the bar was"kind of a private place．"Besides，large parts of Las Vegas will not welcome wearers．
    Google Glass is a pair of glasses with a tiny computer attached to the right earpiece and has the ability to capture any chance encounter and broadcast it to millions．As personal technology becomes increasingly invisible，it is causing questions of whether it will rob people of privacy．
    As Google sees it，Glass is a revolutionary new way to quickly and effortlessly connect people with information．Google stresses that Glass is a work in its early stage，with test versions now being released to 2，000developers．The company hopes they'll be seen as normal and become accepted in the same way smart phones are．The wearer has to speak or touch the device to activate（激活） it，and must look directly at someone to take a photograph or video of them．"We are thinking very carefully about how we design Glass because new technology always raises new issues，"said Courtney Hohne，a Google spokeswoman．
    Critics view Glass as an unfriendly new technology that could rob people of what few privacy they have left．They think Google is downplaying the privacy and security risks．According to Google，it's obvious when someone is taking pictures or recording a video on Glass．Developers，however，are pushing the limits．One created a small sensation in tech circles with a program that eliminated the need for gestures or voice commands．To snap a picture，all the user needed to do was wink（眨眼）．
    Imagine a surveillance（监控） device that you could wear on your body all day without anyone being the wiser．Out on the street，in the subway，at a bar or cafe，people would never know whether the stranger next to them is secretly recording their every move．It is really a privacy disaster．

    41．What can we know from the first paragraph？D
    A．Google Glass sells well in the market．
    B．Google Glass is not welcomed by customers．
    C．Google Glass can not be used in private places．
    D．Google Glass has heard some sort of disapproval．
    42．According to Google Company，which of the following statements about Google Glass is NOT true？C
    A．Google Glass is an immature product．
    B．They are acting cautiously in designing Google Glass．
    C．People can take photos without eyeing the objects．
    D．Google Glass is just as normal as a smart phone．
    43．The underlined part"pushing the limits"in Paragraph 4refers toB．
    A．speeding up the production time of Google Glass
    B．improving the functions of Google Glass
    C．objecting to what Google has said
    D．experimenting with something risky
    44．In the last paragraph，the author wants to tell us thatD．
    A．Google glass is not worth buying
    B．people are constantly monitored
    C．people can become wiser with Google Glass
    D．Google Glass is threatening people's privacy
    45．Which of the followings is the best title of this passage？C
    A．The Disadvantages of Google Glass．
    B．A New Way to Gain More Information．
    C．Privacy Concerns of Google Glass．
