考试点二 (not) so /as…as
比较级特殊句式(not)so/as…as 表明“好似……一样、比不上……”等含意，其构造和than句式差不多，但as…as中间的修饰词务必用原型，并且as…as务必搭配应用，
如：It is as good as it looks.
The boss is not so bad-tempered as you have described.
填空中常会得出语句的一部分(*个as)，规定填出相搭配的一部分(第二个as)，一定要产生对这类搭配句式的比较敏感。
练习题：
(1)
The best way to control rats is by seeing that they have as ----.
(A) possibly little nourishment
(B) nourishment possibly little
(C) little as possible nourishment
(D) little nourishment as possible
回答：D
解释：空格处必须形容词have的宾语，另外包括as…as句式，A、B都缺乏与as搭配的构造，C词序不正确，均可清除。D中as…as possible, 为固定不动用法, 意为“尽量”.
(2)
There is evidence that prehistoric humans used fire ---- 400,000 B.C.
(A) so early
(B) the earliest
(C) as early as
(D) so early that
回答：C
解释：依句意空格处必须“早在”这一含意的恰当表述，仅有C合乎文题，用的是比较级特殊句式as...as
考试点三 the same…as
此句式也常见来表明“和……一样”，the same和as既可并用，也可分离应用，
如：She looks just the same as before.
I got the same feeling as you did.
改错题中常会将此句式错用为the same…like /than, 要练出一双慧眼将其鉴别出去
练习题：
(1)
Meadowlarks are about the same size than robins, but they have heavier bodies, shorter tails, and longer bills.
应改成：as.
解释：the same as是固定不动搭配, 表明“与．．．一样”
(2)
Due to sophisticated transportation networks, people can now buy the same types of perishable goods in Toronto like in New York City.
应改成：as
解释：与the same相搭配的仅有as, like不行
