小学英语单复数的用法

小学英语单复数的用法在英语中,单复数是非常重要的语法概念。
单数表示一个,复数表示多个。
下面我将介绍小学英语单复数的用法。
一、可数名词单复数的规则变化1、规则变化a.在后面加s。
如:book→books,pen→pens,cat→cats。
b.以s,x,ch,sh结尾的单词加es。
如:bus→buses,box→boxes,watch→watches。
c.以辅音字母加y结尾的单词变y为i再加es。
如:family→families,strawberry→strawberries。
d.以元音字母加y结尾的单词直接加s。
如:boy→boys,toy→toys。
e.以o结尾的单词加s或es。
如:photo→photos,radio→radios。
2、不规则变化a.人称代词he,she,it是单数形式,分别是him,her,it。
b.指示代词this,that是单数形式。
c.动词和名词有单数和复数两种形式。
一般来说,主语是单数时用单数动词或名词,主语是复数时用复数动词或名词。
d.在and连接的两个名词作主语时,谓语动词用复数形式。
e.由there、here、in、at等引导的句子中,名词是单数时用单数动词,名词是复数时用复数动词。
f.由some、any、no等引导的句子中,名词是单数时用单数动词,名词是复数时用复数动词。
g.由what、who等引导的句子中,谓语动词的数由后面的名词决定。
如果是单数名词则用单数动词,如果是复数名词则用复数动词。
h.在疑问句中,如果主语是单数,则谓语动词用单数形式;如果主语是复数,则谓语动词用复数形式。
i.在特殊疑问句中,如果主语是单数,则谓语动词用单数形式;如果主语是复数,则谓语动词用复数形式。
在小学英语中,单复数的概念是十分重要的。
许多单词在添加后缀或者变换形式时,都需要考虑到单复数的问题。
而正确地使用单复数形式,也是英语写作和口语表达中的基本要求。
在英语中,单数和复数的概念与中文的相同。

一、第一人称单数:I我。
第二人称:you你。
第三人称单数:he他、she她、it它。

初一英语句型转换试题答案及解析

初一英语句型转换试题答案及解析1.【1】Andy is American. (同义句)Andy ______ _______America.【答案】comes from【解析】句意为:安迪是美国人。
联系转换后的句子可知,其同义于“安迪来自美国”。
由于主语是第三人称单数故可填:comes from或is from。
【2】He is in Huang he Football Team.(同义句)He is_______ _______ _______ Huang he Football Team.【答案】a member of【解析】句意为:他在黄河足球队。
联系转换后的句子可知,其同义于“他是黄河足球队的一个成员”。
“---的一个成员”在英语中应表达为:a member of。
【考点】句式变换。
2.【1】My father and mother are teachers.(改为同义句) My teachers.【答案】parents, are【解析】句意:我的爸爸、妈妈是老师。
这个题目要求我们改为同义句,原句中是用的fatherand mother,爸爸、妈妈,我们可以用一个单词parents来表示相同的意思,即父母,并且因为主语是复数的,所以用are。
【2】The CDs are on the desk. (对划线部分提问) the CDs?【答案】where are【解析】句意:这些光盘在桌子上。
这个题目要求我们对划线的部分进行提问,on the desk的意思是在桌子上,因此我们应该问在哪里,疑问词是where,然后把句中的are提前,变成疑问句。
【3】This is my book.(改为同义句) This book .【答案】is mine【解析】句意:这是我的书。
这个题目要求我们变为同义句,根据句意可知,这是我的书,即这本书是我的。
mine是一个名词性的物主代词,在句中做表语,即my book。
