第二节 限定词4 Z1 W, q& M2 ], A5 L- M
名词究竟要用单数还是复数, 与名词之前的限定词有很大关系, 限定词通常分如下几类:7 ~9 C) H8 I5 Q, ?/ x: z
1．之后肯定接单数: 0 J! ^4 R5 f7 A8 q* d
a /an, every, one, another, each, either, this, that, such a, many a, etc.2 j2 v7 x* P/ y9 s; C' h3 c7 l" C
例句： Each of them has two books.
& m/ C! X% a9 m1 R6 iYou can read either book. （两本书你可以随便读一本）
; H- t c" \! p2．之后肯定接复数:
0 S. n' P" t7 i2 r. [these, those, many, such, other，6 D% G8 A# L( X8 }8 U
大于one的数词(ten, hundred, thousand, million…),
7 F/ r, I9 x6 K" @9 r4 Qa few /few /fewer /fewest, a (great /good / large /small) number of, several
2 H$ e; d5 c, \& M* lone of, all (of), some /any (of), most (of), a lot of, lots of, the rest of, plenty of1 ~4 V0 I1 _! V1 M
3．之后既可接单数又可接复数: the, no, his, her, their, my, etc

考点一 否定限定词no / P* ]6 X( j" S& W$ O V3 W# Z
(1) no既可用于可数名词复数前又可用于单数前, 表示否定意义. 例如:
! p8 K/ i8 V4 ^7 Y; `No flowers in the garden. 花园里没有花.
+ e, x! Z0 E: l) l6 ANo one is here.
- y! ^0 H3 Y& ]/ ~' h& Q4 M(2) no与否定副词not的区别是改错题的常见考点。 二者的区别在于:
& Q0 _7 i1 n. } Q m7 Eno直接修饰名词, 不能与其他限定词同时出现; 9 f6 p# L' g5 u# c6 p
not一般出现在be动词或助动词之后, a, an, any等限定词之前, 它是否定式的组成要素, 而不是名词的限定词

(D) nor
4 j$ t4 j3 c/ c4 @答案: C
% I: m# R# E0 j, I1 w解释: 此句主谓完整, 据选项可知空白处需填入合适的词使原句变为否定, 只有否定副词not可以和is配合构成否定句, A、B、D 之后都需要名词词组, 不符题意 * C' g4 u0 o6 y, ?; E# e
(2)
. l1 c& _2 o- E$ V1 KNot woman held a presidential cabinet position in the United States until 1933, when Frances Perkins became secretary of labor. $ Q% `6 _* l. ~
应改为: No 8 |; q6 `" {) d) x
解释: Not是否定副词应置于be动词或助动词之后, 且它与单数名词间需加冠词, 而no是形容词, 可以直接修饰后面的名词 |
