小学英语不规则名词单复数
一般情况下,直接加s,如:apple-apples,pig-pigs,book-books等。
二、单数句变复数句
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。
1、人称代词由单数变复数:
主格Iwe youyou he/she/it they
宾格meus you you him/her/itthem
例1She is a girl.
例2 I likeher.We likethem.
2、指示代词由单数变复数:
单数thisthat
复数thesethose
例1This is a book .These are(some)books .
例2Is that apen? Are those(any)pens?
3、物主代词由单数变复数:
1、名词性物主代词:mineours,yours yours,his/hers/its theirs
2、形容词性物主代词:myour,youryour,his/her/its their 例1 The bookis mine. The books areours.
例2 This is her pen. Thesearetheir pens.
4、一般情况下,形容词性物主代词在单数句变复数句时不变。
例1 This is my book . Theseare my books .
5、当句中形容词性物主代词与句中的主语一致时,形容词性物主代词
应随主语人称的变化而变化,仍要保持一致。
例1 He likeshis bike.They liketheir bikes.
6、连系动词由单数变复数:is/am are
例1Iam a teacher.We are(some)eachers.
7、a/an表示一个,只能用在单数名词前,当单数句变复数句时,
一定要把a/an去掉,或改为some/any。
例1This isabook . These are(some)books.
例2 Is that a pen?Are those(any)pens?
8、当名词作定语或在介词短语中作介词宾语充当除宾语以外的
其它成分时,该名词不变。
例1 He is a boy student.
They are(some)boy students.(man和woman)除外。
例2She is a womanworker.
They are(some)women workers.
9、单数句变为复数句时,句式不能改变,即单数句是疑问句时,变为复数句时,仍然是疑问句。
例1 What’sthis?What are these?
例2 She likeshis bike.They liketheir bikes.
