考研英语语法归纳和练习
[A]as good as [B]as good [C]good [D]good as
在这里as good as 比较连词与better than比较连词同时出现时候，不能省略任何一个介词。答案为A On the whole, ambitious students are more likely to succeed in their studies than are those with little ambition.
2)比较的成分是否属于同类事物或同类概念，既是说比较要具有可比性。如：
The number of registered participants in this year’s marathon was half .
[A] of last year’s [B]those of last year’s
[C]of those of last year [D] that of last year’s
（前后相比的应该是今年和去年注册参加的人数“the number of”故代替它的应该是单数指示代词“that”，而不能选择B，those是指代participants，不是同类对比，答案为D。
Young readers, more often than not, find the novels of dickens far more exciting than Thackeray’s.
3）比较级与倍数词关系及其位臵
原级结构中可插入表达倍数的词，表示为“为….若干倍”,当与有表示倍数比较的词在一起时候等，他们的位臵是，倍数词+as…as…,或倍数词+more…than…，但again一般放在原级词之后，即 “as+原级＋again+as”.如：
Smoking is so harmful to personal health that it kills people each year than automobile accidents.
[A] seven more times [B] seven times more
[C] over seven times [D] seven times
(答案为B)
“Do you regret paying five hundred dollars for the painting?”“No, I would gladly have paid for it.”
[A] twice so much [B] twice as much
[C] as much twice [D] so much twice

4）下列词和短语不用比较级形式却表示比较概念：
inferior, minor, senior, prior, prefer to, superior, major, junior, preferable, differ from, compared with, in comparison with, different from, rather than. 如：

[A] superior [B] advantageous [C] super [D] beneficial
（答案为A）
Prior to his departure, he addressed a letter to his daughter. (1986年考研题)
5）“比较级＋and +比较级”或“more and more/less and less +原级”以及“ever, steadily, daily等副词＋比较级”结构表示“越来越……”的意思，与这类结构搭配的常用动词有grow, get ,become等。前面两种情况更多地出现在进行时态中，注意的是这三种情况引导的比较级后面都不需要用than.如： Things are getting worse and worse.
As I spoke to him he became less and less angry.
Her health was becoming daily worse
The road got ever worse until there was no road at all = the road got worse and worse.
6)比较级前面可以用even, still, yet ,all the (more)等修饰语用以加强语气，表示“更加”的意思。如 Today it is even colder than yesterday
I have yet more exciting news for you
7) 有关比较级的特殊句型：
