  • 第6题:

    The girls are afraid that being friendly to strangers could be misinterpreted by their__neighbours.

    A. ever-present
    B. ever-presented
    C. ever-presenting
    D. ever-presently

    答案:A
    解析:
    考查形容词的用法。句意为“女孩们担心对陌生人友善会被如影随形的邻居误解”。ever-present修饰名词,表示“时时存在的”,例如,“爱是永恒的”可翻译为love is ever--present。没有B和C这类搭配。形容词修饰名词,排除D选项。所以正确答案为A。
