比较状语从句讲解及精选练习附答案

1、 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。主要运用于形容词和副词的原级、比较级及最高级的句子之中。原级：asas（和一样），not so（as）as （和不一样）；比较级：morethan（更）；最高级：The mostin/of， the + 形容词+estof/in。一原级比较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

2、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），twice（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 twice as thin as that one.

3、 这本书的厚度是那本书的二分之一。2. 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 soas比not asas用得比较普遍。例如：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。二比较级1. 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（

4、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。Man grows faster than the planet he inhabits. 人类成长的速度远比他居住的星球快得多。注意： 从句中的主语（名词）如果与主句中的主语一致，为了避免重复，常用that代替不可数或某可数名词，用those代替可数复数名词，用one或ones代替可数名词。例如： The result of this experiment is better than that of the last one. 这次实验的结果要比上次好。The students in

5、our class are more diligent than those in their class. 我们班的学生比他们班的学生用功。 比较状语从句的动词，如果与主句的谓语动词一致，且为行为动词时，常用do（does，did）代替，以免重复。例如： We have produced even more coal this year than we did that year. 我们今年出产煤要比去年出产得更多。 She drives better than her husband does. 她开车开得比她丈夫好。2. “no+比较级+than”（不比···

6、;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。 “ not more than” 不如 (前者不如后者) Jack is not more diligent than John. 杰克不如约翰勤奋。3 句型the···the··

7、83;（越···越···）。即：从句：the + 比较级···，主句：the + 比较级···The more we study, the more we discover our ignorance. 我们越学习，就越发现自己无知。主句如果是将来时，从句可用现在时代替将来时。例如：The longer the treatment is delayed, the worse the prognosis will be. 延误治疗的时间越长，预后越差。三最高级1. The mo

8、stin/of This book is the most interesting of the three. 这本书是三本中最有趣的。 2. the + 形容词+estof/in This road is the busiest street in our city. 这条路是我们城市最繁忙的街道。 3. one of the + 名词(复数).之一(用于最高级) Tom is one of the best students in our school.
