英语单数句变复数句的八种类型及口诀速记

单数句变复数句1、人称代词主格单数变成相应的人称代词主格复数，即Iwe;youyou;she,he,itthey。 如：She is a girl. They are girls.2 am, is 变为 are。 如：I'm a student. We are students.3不定冠词 a, an 要去掉，固定搭配除外。如：He is a boy. They are boys.4可数名词单数要变为复数形式。如：It is a cat. They are cats.5指示代词 this, that 变为 these, those。如：This is a book. These are books.6 man, woman 作定语修饰可数名词时，要在 "数"上与被修饰名词保持一致。但其他名词修饰名词表示 "性质"时，不作变化。如：六、man或woman修饰可数名词时，在整个句子变成复数的情况下，它们也变为复数形式men, women。例如： She is a woman teacher.They are women teachers. 注意：普通单数可数名词要变为复数形式，但当名词修饰名词表示“性质”时不作变化。例如：apple/banana/orange/pear treeapple/banana/orange/pear trees苹果/香蕉/桔子/梨树；boy/girl studentboy/girl students等。 七、单数句变复数句时，句中的形容词、定冠词、副词、疑问词、介词短语和感叹词等保持不变。例如： Who is she? 她是谁？Who are they? 她们是谁？ 八、此外，还须注意的是并不是所有的英语单数句子都可以变成复数句子。例如： My name is Kate. 我叫凯特。 Three plus two is five. 三加二等于五。记住单数句变复数句的口诀。 单数句子变复数，变化规则要记住。 名词代词要变化，am, is 要变are。 this, that 该咋办，these, those 替代它。 he, she, it 要变啥，全部变 they 就行了。 I要变 we 别落下，名词后面把 s/es加。 名前冠词去掉它，其余成分原样加。但是，在英语中有些单数句不能变为复数句，如：Lily is fourteen.(莉莉十四岁。)His name is Jim.(他的名字叫吉姆。)等把单数的句子成复数的句子很简单：变法是把能变成复数的词变成复数，但a或an要把去掉。特殊疑问词、形容词、国家及地点通常不变。把下列句子变成复数1  I have a car.                                   2   He is an American boy.                         3  It is a car .                                 4  This is an eraser .                               5  That is a backpsck.                  6 I'm an English teather .                        7 It's a new shirt .                                 8 He's a boy .                         9 She's a singer .                                    10 What's this in English?                  小学五年级英语(上)-就划线部分提问方法:用特殊疑问词代替划线部分,其余的变为一般疑问句放在其后,注意:划线部分不能在问句中出现.1. 就名字提问,用what.(1) My names Zhou Pei.(2) His name is Tom.(3) Her name is Mary. 2.就班级/年级提问,用what.(4)Im in Class One.(5)He is in Grade Four.(6)They are in Class Three. 3.就人提问,用who(7)He is Bob.(8)That girl is my new friend.(9)Shes my aunt.(10)They are my grandfather and grandmother. 4.就年龄提问,用how old(11)Shes ten.(12)They are twelve.(13)Im eleven.(14)My brother is four. 5.就地点提问,用where(15)He is from France.(16)Im from China.(17)I come from New Zealand.(18)He comes from Australia.(19)They come from Japan.(20)The ball is in the box.(21)They work in a factory.(22)My uncle works in a bank. 6.就职业提问,用what(23)Shes a nurse.(24)My dad is a doctor. 7.就所属提问,用whose(25)These are my books.(26)That is his panda.(27)This is Bobs mug. 8.就事物提问,用what(28/)This is a book.(29)Thats a camera.(30)They are apples. 9.就数量提问,用how many(31)There are four people in my family.(32) I have five  pencils.(33) I can see two pens on the desk. 10.就时间提问,用what time(34) Its four oclock.(35)He goes to school at seven. 答案1.Whats your name?2.What is his name?3.
