    "Indeed," George Washington wrote in his diary in 1785, "some kind of fly, or bug, had begun to eat the leaves before I left home." But the father of America was not the father of bug. When Washington wrote that, Englishmen hade been referring to insects as bugs for more than a century, and Americans had already created lightning-bug(萤火虫). But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

    　　The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.

    　　Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug, that is, "to install (安装) an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversation. Since the 1840s, to bug has long meant "to cheat", and since the 1940s it has been annoying.

    　　We also know the bug as a flaw in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as "little problems and difficulties" that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison "had been up the two previous nights discovering 'a bug' in his invented record player."

    1.We learn from Paragraph 1 that __________________.

    A. Americans had difficulty in learning to use the word bug

    B. George Washington was the first person to call an insect a bug

    C. the word bug was still popularly used in English in the nineteenth century

    D. both Englishman and Americans used the word bug in the eighteenth century

    2.What does the word "flaw" in the last paragraph probably mean?

    A. Fault.      B. Finding.        C. Origin.      D. Explanation.

    3.The passage is mainly concerned with__________________.

    A. the misunderstanding of the word bug

    B. the development of the word bug

    C. the public views of the word bug

    D. the special characteristics of the word bug
