一、原级比较的基本用法。
1. 原级比较由“as+形容词或副词(或再加名词或短语)+as ”构成“原级相同”比较句，表示两者比较；其否定式，即“程度不及”比较句型为“not so(as) +形容词或副词+as”,而且as…as结构前可用just, almost, nearly, quite等表示程度的词修饰。
1) walking briskly for thirty minutes will burn as many calories as .
〔a〕 to run for fifteen minutes
〔b〕 running for fifteen minutes
〔c〕 you run for fifteen minutes
〔d〕 fifteen?minute walking

3) alaska is twice 〔a〕 as larger 〔b〕 as 〔c〕 the next largest 〔d〕 state, texas.
2. “as (so)+名词+as+名词”进行名词比较，这时一般情况下有一个表示原级的比较词，但如果第一名词前出现了形容词修饰该词或出现副词修饰谓语，应当用so而不用as
4) thomas jefferson’s achievements as an architect rival his contributions a politician.
〔a〕 such
〔b〕 more

〔d〕 than
5) i should say henry is not much a writer as a reporter. (88年考题)

〔b〕 so
〔c〕 this
〔d〕 as
二、比较级。
1. 比较级由“形容词(副词)比较级+than+…,构成表示在两者中间一方比另一方“更加…”.连词than后可接句子，也可接名词、代词、名词短语、介词短语、动词、动词不定式、?
ing结构和？ed结构，有时也可省去than.
6) natural mica(云母) of 〔a〕 a superior 〔b〕 quality is cheapest 〔c〕 to obtain than synthetic 〔d〕 mica.

2. 注意than前后两项相比较的人或事物要一致。
