名师辅导不含糊:托福语法全攻略(13)

  考点二 (not) so /as…as

  比较级特殊句式(not)so/as…as 表示“如同……一样、不如……”等意思,其结构和than句式相仿,但as…as之间的形容词必须用原形,而且as…as必须搭配使用,

  如:It is as good as it looks.

  The boss is not so bad-tempered as you have described.

  填空题中常给出句子的一部分(第一个as),要求填出相搭配的部分(第二个as),一定要形成对这种搭配句式的敏感。

  例题:

  (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

  答案:D

  解释:空格处需要动词have的宾语,同时包含as…as句式,A、B都缺少与as搭配的结构,C语序有误,均可排除。D中as…as possible, 为固定用法, 意为“尽可能”.

  (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

  解释:依句意空格处需要“早在”这一意思的正确表达,只有C符合题意,用的是比较级特殊句式as...as

  考点三 the same…as

  此句式也常用来表示“和……一样”,the same和as既可连用,也可分开使用,

  如:She looks just the same as before.

  I got the same feeling as you did.

  改错题中常将此句式误用为the same…like /than, 要练就一双火眼金睛将其识别出来

  例题:

  (1)

  Meadowlarks are about the same size than robins, but they have heavier bodies, shorter tails, and longer bills.

  应改为:as.

  解释:the same as是固定搭配, 表示“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.

  应改为:as

  解释:与the same相搭配的只有as, like不行
