ing-bottom: 70.63%;">表示倍数时通常借助half, double, twice, three times等之类的词。如:Half (of) the apples are bad. 一半苹果是坏的。His homework is not yet half done. 他的作业还没完成一半。He eats twice what I eat. 他的食量是le: exactly">比较以下三句,虽然表达形式不同,但含义相同。如:(1) This rope is three times as long as that one. 这根绳子是那根的三倍长。(2) This rope is three times longer than that one. 这根绳子是那根的三倍长。(3) This rope is three times the length of that one. 这根绳子是那根的三倍长。第(1)句和第(3)句的意思比较清楚,但第(2)句常容易误解,有人认为它与其他两句意思不同,应理解为“这根绳子比那根绳子长三倍”,但绝大多数语法学家并不这样认为,而是认为以上三句意思相同。
