题目

Around two o'clock every night, Sue will start talking in her dream. It somewhat ________ us. A．bothers  B．had bothered C．would bother  D．bothered 答案： A。考查动词时态。解题思路：从状语around two o’clock every night可判断出，本句要用一般现在时，will start表示现在的趋势而非将来时，故选择A。 【句意】每晚两点左右，他总是开始说梦话，多少总会打搅我们。13．已知a2x=3，求$\frac{{a}^{3x}+{a}^{-3x}}{{a}^{x}+{a}^{-x}}$的值．
