比较状语从句 比较状语从句表达人或事物的属性或特征的不同程度。常由as···as(和···一样),not as / so···(不像···那样),than(比),the···(越···越···)等引导。 1. as+原级+as(第一个 as 是副词,含“如此”的意思,在主句说明所比内容的程度;第二个 as 是连词,含“比”或“如此”的意思,引导从句)。例如: Our classroom is as big as theirs. 我们的课室跟他们的一样大。 I hope you like it as much as I do. 我喜欢你跟我一样喜欢它。 在这种结构中,比较成分的前面常用表示倍数的词如···times(···倍),tw ice(两倍)等来表示相比较的两个成分相差的倍数,通常译作“像···几倍那样多”,“是···的几倍”。例如: The speed of sounds in water is about four times as great as in air. 声音在水中的速度是空气中的4 倍左右。 This book is tw ice as thin as that one. 这本书的厚度是那本书的二分之一。 2. “no+比较级+than”(不比···多,不少于)。no 是副词,在主句中作状语,修饰形容词或副词的比较级;than 是连词,引导从句。例如: Tom is no less diligent than peter. 汤姆用功不比彼得差。(汤姆和彼得同样用功) He feels no better today than he did yesterday. 他今天的感觉不比昨天好。(他今天的感觉跟昨天同样不好。) 3. not so / as ···as(不像···那样,不如)。第一个 as/so 是副词,在主句中作状语,修饰其后的形容词/副词;第二个 as 是连词,引导从句。not so···as 比not as···as用得比较普遍。例如: The weather is not so cold as it was last winter. 天气不如去年冬天那么冷。 It is not as easy as you think. 事情并不像你想的那么容易。 The work did not go so smoothly as we hoped. 这工作并不像我们希望的那样顺利。 4. 形容词/副词的比较级+than+被比较的对象。表示两个人或事物在某(些)方面的差别。than 是连词,引导从句。后面被比较对象如果是名词,多用省略形式,省去与主句中相同的部分。 This flower is less beautiful than that one but sweeter than that one. 这朵花不如那朵花看,但比它香。 Man grows faster than the planet he inhabits. 人类成长的...
