易错易混知识总结
一、易混点归纳
(一)some,any及some-,any-,every-复合不定代词1.some一般用于肯定句,any一般用于否定句、疑问句。但在下列情况下多用some:
(1)some后接单数可数名词,意为“某一”时,相当于“ a certain + 单数可数名词”;
(2)在表示请求或邀请的句子中,期望对方给予一个肯定的答复时,通常用some,而不用any。
2.any常用于下列肯定句中:
(1)用于陈述句或祈使句中,后接可数名词单数形式表示“任何;无论哪一个”;
(2)用于肯定的条件句中,意为“什么;一个(些)”;if any是固定词组,意为“如果有的话”。
Some,any,every常与-one,-body,-thing构成复合不定代词,与some,any,every用法基本相同。
(二)other,the other,another和others
指代单数时,若是泛指,用another;若是特指,则用the other。
指代复数时,若是泛指,用other修饰名词的复数形式;若是特指,用the other修饰名词的复数形式。
others不能作定语,表示复数意义,相当于“other + 复数名词”;the others相当于“the other + 复数名词”。
another一般表示单数,其后接可数名词的单数形式。但若其后有数词或few时,则可接复数名词。
(三)both,either,neither,all和none
both,neither和either都表示两者,可作主语、宾语和定语。both还可做同位语。both表示肯定,意为“两
者都”;neither表示对两者的全部否定,意为“两者都不”;either表示两者中任何一个。
all和none表示三者或三者以上。all可作主语、宾语、表语、定语和同位语,表示全部肯定。None可作主语、宾语和同位语,但不能作定语,表示全部否定。
all作主语,指人时看作复数,指事物时看作单数;none做主语,看作单复数皆可。
(四)one,ones,that和those
one和ones表示泛指,代替上文提到的可数名词,one指代单数,ones指代复数,可有前置定语或后置定语,也可单独使用。如果其前面有定冠词the则表示特指。
that用来代替前面提到过的单数可数名词或不可数名词,不能和冠词连用,其后常有修饰语。those代替可数名词的复数。
