第二节 限定词



名词到底要用单数還是复数, 与名词以前的限定词有非常大关联, 限定词一般分以下几种:

1.以后肯定接单数:

a /an, every, one, another, each, either, this, that, such a, many a, etc.

词组: Each of them has two books.

You can read either book. (两本你能随意读一本)

2.以后肯定接复数:

these, those, many, such, other,

超过one的数词(ten, hundred, thousand, million…),

a few /few /fewer /fewest, a (great /good / large /small) number of, several

one of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of

3.以后既可接单数又可配复数: the, no, his, her, their, my, etc

留意:这几种词大多数不可以另外应用

考试点 否定限定词no

(1) no既可用以可数名词复数前又可用以单数前, 表明否定实际意义. 比如:

No flowers in the garden. 公园里没有花.

No one is here.

(2) no与否定副词not的区别是改错题的普遍考试点。 二者的区别取决于:

no立即修饰名词, 不可以与别的限定词另外出現;

not一般出現在be动词或助动词以后, a, an, any等限定词以前, 它是否定式的构成因素, 而不是名词的限定词

练习题:

(1)

The mechanism by which brain cells store memories is ---- clearly understood.

(A) none

(B) no

(C) not

(D) nor

回答: C

表述: 此句主谓详细, 据选择项得知空白需填写适合的词使原话变成否定, 仅有否定副词not能够 和is相互配合组成否定句, A、B、D 以后都必须名词短语, 不符合文题

(2)

Not woman held a presidential cabinet position in the United States until 1933, when Frances Perkins became secretary of labor.

应改成: No

表述: Not是否定副词应放置be动词或助动词以后, 且它与单数名词间要加冠词, 而no是修饰词, 能够 立即修饰后边的名词
