形容词、副词的比较级、最高级： 考点讲解与训练 一、两者相比，甲=乙，用“as +形容词或副词原级+ as”。如： He is as tall as me. He got up as early as I did. 二、两者相比，甲＜乙，用“not as/so+形容词或副词原级+as”。如： He cannot run so/as fast as you. Corn doesn’t need as/so much water as rice. 1、as„as 结构的基本用法 其基本意思为“与„„一样”，其中的第一个as 副词，其后通常接形容词或副词(用原级)，第二个as 可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点： （1）在否定句中，第一个 as 也可换成 so： He doesn’t study as [so] hard as his brother. （2）两个as 之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much+不可数名词+as”和“as many+可数名词复数+as”： You’ve made as many mistakes as I have.

We’ve got food for as many people as want it. （2）若第二个as 用作连词引导一个表示将来意义的从句，则该从句可用现在时表示将来，也可直接使用将来时态。如： We’ll get there as soon as you do [will]. 3、as„as„结构的修饰语 该结构根据情况可用使用以下修饰语：(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent 等，并且这些修饰语必须置于第一个as 之前，而不能置于其后。如： He doesn’t play half as well as his sister.
