考點(diǎn)二 (not) so /as…as
比較級(jí)特殊句式(not)so/as…as 表示“如同……一樣、不如……”等意思，其結(jié)構(gòu)和than句式相仿，但as…as之間的形容詞必須用原形，而且as…as必須搭配使用，
如：It is as good as it looks.
The boss is not so bad-tempered as you have described.
填空題中常給出句子的一部分(第一個(gè)as)，要求填出相搭配的部分(第二個(gè)as)，一定要形成對(duì)這種搭配句式的敏感。
例題：
(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
答案：D
解釋：空格處需要?jiǎng)釉~have的賓語，同時(shí)包含as…as句式，A、B都缺少與as搭配的結(jié)構(gòu)，C語序有誤，均可排除。D中as…as possible, 為固定用法, 意為“盡可能”.
(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
答案：C
解釋：依句意空格處需要“早在”這一意思的正確表達(dá)，只有C符合題意，用的是比較級(jí)特殊句式as...as
考點(diǎn)三 the same…as
此句式也常用來表示“和……一樣”，the same和as既可連用，也可分開使用，
如：She looks just the same as before.
I got the same feeling as you did.
改錯(cuò)題中常將此句式誤用為the same…like /than, 要練就一雙火眼金睛將其識(shí)別出來
例題：
(1)
Meadowlarks are about the same size than robins, but they have heavier bodies, shorter tails, and longer bills.
應(yīng)改為：as.
解釋：the same as是固定搭配, 表示“與．．．一樣”
(2)
Due to sophisticated transportation networks, people can now buy the same types of perishable goods in Toronto like in New York City.
應(yīng)改為：as
解釋：與the same相搭配的只有as, like不行
