英语六级基础语法：形容词、副词及其比较级

1.形容词的句能

形容词在句中做定语、表语和主语。考生应注意：

(1)以 a 开头的形容词如alone, alike, asleep, awake等不能做前臵定语，可做表语或后臵定语。

(2)某些以副词词缀 -ly 结尾的词是形容词，如friendly, leisurely, lovely等。

(3)下列动词既是实义动词又是系动词，注意用做系动词时，要求形容词做表语：remain, keep, become, get, grow, go, come, turn, stay, stand, run, prove, seem, appear, look。

2.考比较级时，考生应把握

(1)形容词和副词比较级的形式是否和比较连词对应出现，即是否符合原级比较及比较级的结构。

如： 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。

如： Young readers, more often than not, find the novels of Dickens far more exciting than Thackerays.

(3)比较级的修饰语如 a little, a lot, the, any, even, far, hardly, lots, much, rather，还有表示倍数比较的词等，他们的位臵是：修饰语 asas, 或修饰语 morethan。

如： Smoking is so harmful to personal health that it kills seven times more people each year than automobile accidents.

(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： Their watch is superior to all the other watches on the market.

3.高级形式应注意的问题

比较级形式表示高级意义时，比较对象的范围应用： any other 单数名词 the other 复数名词 the others、 anyone/anything else

上述词是用来将比较级结构转变成高级意义的关键词语，切不可遗漏，否则会造成逻辑混乱的错误。如不能说：John runs faster than anyone.注意与汉语表达的不同。

4.有关比较级的特殊句型

(1)not so muchas与其说不如说

The chief reason for the population growth isnt so much a rise in birth rates as a fall in death rates as a result of improvements in medical care.

(2)no/not any morethan两者一样都不

There is no reason they should limit how much vitamin you take, any more than they can limit how much water you drink.

(3)no /not any lessthan两者一样都 She is no less beautiful than her sister.

(4)just asso.正如，也(用倒装结构) Just as the soil is a part of the earth, so is the atmosphere.
