摘要:下面是小编为即将参加托福考试的同学汇总了托福考试的语法知识点,名师指导绝不含糊,供各位考生参考。

  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
