  • 第5题:

    The Moon and most artificial satellites travel around the Earth in elliptical paths

    A: waves
    B: orbits
    C: voyages
    D: flights

    答案:B
    解析:
    句意:月亮和人造卫星都以椭圆轨道绕地球旋转。画线单词path意为“路径”。 wave意为“波浪”;orbit意为“轨道”;voyage意为“航海”;flight意为“航班”。根据画线单词意思,只有orbit与其意义相近,可进行替换。因此B项正确。
