五年级英语基础知识3
一．句子单复数的互变。
同学们都会把单数可数名词变为复数，如何把单数句子变为复数句子呢？若掌握了下面九条规则，在做题时你就会易如翻掌的。
（1）指示代词由单变复：this→these,that→th ose
（2）、人称代词由单变复：主格：I→we,you→you,he/she/it→they
（3）物主代词由单变复：形容my→our,your→your,his/her/its→their.
(4) 联系动词由单变复：am/is→are.
(5) a/an表示“一个”，只能用在单数名词之前，当单数句子变为复数句子时，一定要把a/an去掉，或改为some/any，
(6)、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他成分时，该名词不变，如：He is
a boy student→They are(some) boy students.(man和woman除外)。
(7)、一般情况下，形容词性物主代词在单数句子为复数句子时不变，如：This is my pen→These are my pens.
(8)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改变而变化，仍要保持一致，如:He likes his bike→They like their bikes.
九、单数句子变成复数句子时，句式不能改变，即单数句子是疑问句，变为复数句子时仍然是疑问句，如：What's this?→What are these?
二．同学们明白了吗?下面来考考你：将下列单数句子改为复数句子:
(1). This is a chair. ( 2).This isn’t an old chair.
(3).He is a boy student. (4).Is he a boy?
(5).What's that? That's an egg. (6).Is this her bag? No,it isn't.
(7).Is she a woman doctor? (8) He likes his dog .
(9)He’s my good friends . (10) Is that a baby .。
