④在"more...than..."中，肯定"more"后面的而否定"than"后面的，约等于"是……而不是……"或"与其说是后者，不如说是前者"如：

to remain silent / standing / seated / motionless  保持沉默/站着/坐着/不动

(3)停留： [v + adv. / prep]

考例1. (2009四川) Please remain ______ until the plane has come to a complete stop.

A. to seat B. to be seated C. seating D. seated

解析：答案是D。seat sb 意为"让某人坐下"，所以某人坐着即为 "(Sb) be seated"。

而remain同be一样也是系动词，所以后面也接seated。也可以把seated看作一个表状态的形容词"坐着的"。 remain 表示"依然，继续"，为系动词，后加名词，形容词或分词做表语。

考例2. With the ______ five dollars, she bought a pair of shoes for her daughter.

A. more B. remaining C. left D. rest

解析：答案是B。remain表"剩下"为不及物动词，表主动不用被动，所以它的形容词形式为-ing. C选项的left 做后置定语。D项的rest为名词，可带of短语，不修饰名词。

9. It can be proved that China has more population than any other countries in the world. 可以证明，中国人口比世界上任何其他国家都多。
