Unit2 Go for it!语法讲解与练习 both /either/neither /all/none考点梳理 一、基本含义对比 代词 适用范围 含义 语气 核心搭配 both 仅两者 两者都（肯定） 肯定 both...and... either 仅两者 两者中任意一个（肯定） 肯定 either...or... neither 仅两者 两者都不（否定） 否定 neither...nor... all 三者及以上/不可数 全部都（肯定） 肯定 all of... none 三者及以上/不可数 全部都不（否定） 否定 none of... 二、分类考点精讲 1. both（两者都） 含义:专门指代两个人/物,表 “两者都”,永远是肯定含义。 主谓一致规则:作主语时,谓语动词必须用复数。 ✅ Both of my parents are teachers. ❌ Both of my parents is teachers. 高频搭配：both A and B(A和B都),作主语时谓语用复数。 例句：Both you and he are good at English. 易错点： o不能用于三者及以上,不能说 both of the three books. o本身是复数,不能接单数动词,也不能和 not 连用（表部分否定用 not both） 2. either（两者中任意一个） 含义：指代两者中的 “任何一个”,表肯定选择。 主谓一致规则：作主语时,谓语动词必须用单数。 ✅ Either of the two answers is correct. ❌ Either of the two answers are correct. 高频搭配：either A or B（要么 A,要么 B），作主语时谓语动词遵循就近原则。 例句：Either you or he is wrong. 易错点： o不能用于三者及以上,不能说 either of the three. o表示 “也” 时,用于否定句（I don't like it, either.),和这里的不定代词用法区分开。 3. neither（两者都不） 含义：指代两者中的 “一个都不”，表完全否定。 主谓一致规则：作主语时，谓语动词必须用单数。 ✅ Neither of the two answers is correct. ❌ Neither of the two answers are correct. 高频搭配：neither A nor B（既不A也不B),作主语时谓语动词遵循就近原则。 例句：Neither you nor he is wrong. 易错点： o本身已含否定含义,不能再和 not 连用,不能说 neither of them didn't go. o不能用于三者及以上，三者及以上的 “都不” 要用 none. 4. all（全部都） 含义：指代三者及以上的人/物,或不可数名词,表 “全部都”。 主谓一致规则： o指代可数复数名词时,谓语动词用复数。例句：All of the students are here. o指代不可数名词时,谓语动词用单数。例句：All the water is gone. 高频搭配：all of...（后接名词时,名词前要有the/物主代词） 易错点： O all 表部分否定时,要和 not 连用： Not all students like math.（不是所有学生都喜欢数学） 不能说 All students don't like math.（易被误解为 “所有学生都不喜欢”） 5. none（三者及以上都不） 含义:指代三者及以上的人/物,或不可数名词,表“一个都不/一点都不”,完全否定。 主谓一致规则： o指代可数复数名词时,谓语动词单复数均可（正式文体用单数,口语中复数更自然，考试优先按单数记）。例句：None of the students is/are late. o指代不可数名词时,谓语动词只能用单数。例句：None of the milk is left. 高频搭配：none of...（后接名词时,名词前要有 the/物主代词） 易错点： o本身已含否定含义,不能再和 not 连用。 o回答 how many/how much 提问时,只能用 none,不能用 no one 问句：How many books are there on the desk? 答句：None.（不能说 No one.） 三、易混点对比（考试高频坑） *both vs. all o两者用 both,三者及以上用 all o例：Both of my hands are clean. / All of my fingers are clean. either vs. neither o肯定选一个用 either，两者都不选用 neither o例：You can take either of the two pens. / Neither of the two pens works. neither vs. none o两者都不用 neither，三者及以上都不用 none o例：Neither of the two shops is open. / None of the three shops is open. 主谓一致的特殊情况 both...and...：谓语永远复数。 either...or... / neither...nor...：谓语就近原则 none of +复数名词：单复数均可,考试优先单数。 四、补充:和of 搭配的规则 当这些代词后面接名词时,如果名词前有the/物主代词/指示代词,必须加 of： ✅ both of my parents ✅ either of the two books ✅ neither of these answers ✅ all of the students ✅ none of his friends 如果名词前没有限定词,直接接名词,不加of： ✅ both parents ✅ all students ❌ both of parents 【巩固练习】 一、用 both /either/neither /all/none填空 1.My parents are ________ doctors.
