    The Internet joins millions of computers, and today it is used by people all over the world. It was
    11 in the 1960s in the USA. The American government needed a network of computers for its army. Then in the 1970s, businessmen also wanted to send and receive 12 with the Internet. But at that time, the messages were only very 13 words without photos.
    The World Wide Web was invented by a British scientist 14 Tim Berners-Lee in 1989. He wanted to send documents (文件) to other scientists, so he developed the World Wide Web. This allowed 15 to send and receive multimedia(多媒体) documents.
    So what's the difference between the Internet and the World Wide Web The Internet is the hardware(硬件). It allows us to 16 with other people. The World Wide Web is the software(软件). It allows us to create, see and read multimedia documents. The Web that is 17 millions of documents called Web pages. These pages are held in 18 all over the world.
    The email is a way of using your computer to send and receive messages. It's 19 and quicker to use emails than to send normal mails. New users call the normal mail“snail mail” because it works too 20 . What will happen next on the Internet Let's wait and see.
    ( )11. A. invented B. improved
    C. borrowed D. copied

    (5)的同系物比少3个碳原子,则符合下列条件的的同分异构体共有 种。
    i.苯环上有两个取代基且其中一个是 ii.碱性条件下可以发生水解反应
    其中核磁共振氢谱五组峰的结构简式为 (任写一个)。
    (6)由A到B的反应过程如图所示:
    中间体K的结构简式为 。
    参考答案
    1.A


    故选C;
    ②贮存氦气时,能将6000L的氦气压缩贮存在40L的钢瓶中的原因是:分子之间存在间隔,受压后,分子之间的间隔变小;
    (2)工业上常用电解熔融氯化锂的方法冶炼金属锂,同时产生氯气,反应的文字表达式为:;
    (3)由化学式可知,淀粉中碳元素和氧元素的质量比为:;
    淀粉中C、H、O元素的质量比为:,故质量分数最大的元素是氧元素;
    (4)在原子中,质子数=核外电子数,故38=2+8+18+8+x,x=2,锶原子的最外层电子数为2,小于4,在化学反应中容易失去最外层2个电子,从而带上2个单位的正电荷,形成Sr2+;
    C粒子与锶原子的最外层电子数相同,均是2,化学性质相似,A粒子的最外层电子数也是2,但是A粒子只有一个电子层,达到了相对稳定结构,而锶原子在化学反应中容易失去电子,两者化学性质不相似;
