3、his book is twice as thin as that one. 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

4、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（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 l

5、ast one. 这次实验的结果要比上次好。The students in 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

6、好。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。 “ 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t
