第四章形容词和副词的比较等级第1讲关于than和as考点1.as…as与(not) as (so)…as①在as…as句型中，第一个as是副词，用在形容词和副词的原级前，常译为“同样”。
后面的as是连词。
He is tall.他高。
He is as tall. 他同样高。
（as修饰tall,“同样”，为副词）He is as tall as his brother is（tall）. 与他弟弟一样, 他是同样地高。
(后面的as为连词，同……一样。
)②只有在否定句中，第一个as才可换为so。
改错：He is so tall as his brother.答案：so改为as1.【1994全国】John plays football _____, if not betterthan, David.A. as wellB. as well asC. so wellD. so well as2.—Did you enjoy the movie last night?—Yes, I didn’t expect it _____ wonderful.A. moreB. asC. mostD. much考点2.在比较状语从句中，主句和从句的句式结构一般是相同的与as…as句式中后一个as一样，than也是连词。
as和than这两个连词后面的从句的结构与前面的句子结构相同，相同部分可以省略。

by far的用法：用于强调，意为“……得多”“最最……”“显然”等，可修饰形容词或副词的比较级和最高级，通常置于其后，但是若比较级或最高级前有冠词，则可置于其前或其后。
如：It’s quicker by far to go by train. 乘火车要快得多。
She ran fastest by far. 她跑得最快(显然她跑得最快)。
He’s by far the cleverer student.他是个聪明得多的孩子。
