90. A major cannadian city, Motreal is (second) only (to) paris (as) (the most largest) French-speaking city in world.
为什么second 前不用加the?
114.In physics, sound is (considered) to be the waves of vbratory (motion), (neither) or not they are heard by (the) human ear.
为什么motion 不用加"s", motion做运动讲不是可数名词吗? 就象pp1-77中的motions
举报
be second to...仅次于...,固定用法
motion做运动讲可数?那个是不是译作“动作”?要不你把那个题贴上来
70. Stars provided early (astronomer) with a (reference) system for measuring (the motions) of planets, the Moon, and the sun.
为什么这题的motions是加"s" 呢?
很是棘手啊!!
我的猜测:motion若是讲抽象的运动(比如说运动和静止),不可数;若是指具体物体、天体的运动(移动),可数。
大家讨论。
