单数句变复数句 默认分类 2010-10-06 18:48:57 阅读127 评论0 字号：大中小 订阅 1．人称代词单数变成相应的人称代词复数,即a主格:I→we;you→you;she/he/it→they.b宾格me →us you→you her/him/ its→them. 如：She is a girl.→ They are girls.2.物主代词由单数变成相对应的复数,即a,形容词性物主代词：my→our ; your→your; his/her/its→their.b 名词性物主代词：mine→ours;yours→yours; his/hers/its→theirs.3． be动词：am is变为are.如：I'm a student. →We are students.4．不定冠词a an 表示“一个”,只能用在单数句中,当变成复数句时,一定要把aan去掉或改为 some/any.如：He is a boy. → They are (some) boys. 5．普通单数名词要变为复数形式.如：It is a cat. →They are cats.6．指示代词 由单变复.即this变为these；that 变成those.如：This is a book.→ These are books.7．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：He is a man doctor.→They are men doctors.This is an apple tree.→They are apple trees.8. 一般情况下,形容词性物主代词在单数句变成复数句时不变.如：This is my pen.→These are my pens.9. 当句中形容词性物主代词与句中的主语一致时,该物主代词应随主语人称的变化而变化,仍要保持一致.如：He likes his bike.→They like their bikes.10. 单数句变成复数句时,句式不能变.即单数句是疑问句时,变成复数句时仍然是疑问句.如：What's this?→What are these? ※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.
