1. Experts generally agree that diet has an important bearing on ones health.
    A) result B) factor C) cause D) influence
    答案及解析: D。 解題思路：從習(xí)慣搭配的角度解題：只有D才能和介詞on搭配使用。
    補(bǔ)充：
    influence n. （常與on連用）影響力；感化力; vt. 影響
    e.g. Many a woman has had an influence upon her husband. 許多婦女對(duì)其丈夫有影響。
    Bearing: n. （與on, upon連用）關(guān)系
    e.g. What they have done has no bearing on the promotion of sales.
    他們所干的事情與這次促銷活動(dòng)毫無聯(lián)系
