    单选题
    The newest fiber-optic cables that carry telephone calls cross-country are made of glass so ______ that a piece 100 miles thick is clearer than a standard windowpane.
    A

    fragile

    B

    immaculate

    C

    iridescent

    D

    tangible

    E

    transparent


    正确答案: A
    解析:
    根据句法关系可以判断,后半句“a piece 100 miles thick is clearer than a standard windowpane”是对空格处词语的进一步解释,主要说明光纤电缆的材料的透明度比较高,因此选项中符合句意的只有E transparent(透明的;清澈的);A fragile 脆弱的,易碎的;B immaculate 完美的,洁净的,无瑕疵的;C iridescent 彩虹色的,闪光的;D tangible 有形的,切实的,可触摸的。
