Be动词的讲解
Be动词用法及综合练习
一.基本形式:

二.定义:
1.是(表状态)(打开书本P77-P78,找出一下意思的句子)
Ex:
A.Iamveryhappy.
B.Theyareourfriends.
2.在(表存在,位置)

单数(I):
am
Iamaboy.
复数(We):
are
Wearestudents.
第二人称
单数(you你):

Youaregirl.
复数(you你们):
are
Youareyoung.
第三人称
单数(she、he、it):
is
Heisright.
复数(they):
are
Theyarecoming.
四.Be动词的否定
1.含be动词(am、is、are)的肯定句在be动词后加not,即变成否定句的格式:
肯:
主词+am/is/are+……
否:
主词+am/is/are+not……
Ex:
肯:
Heisagoodfather.
否:
Heisnotagoodfather.
练习isabadgirl.(写出否定句)
2.Itisadog.
3.be动词可以跟not缩写在一起
isnot=isn’tarenot=aren’t(注意:
amnot一般不缩写)
Ex:
Heisnotagoodfootballplayer.
=Heisn’tagoodfootballplayer.
练习arenotahard-workingboys.(写出它的缩写句)
isnotgoodatdancing.
五.Be动词的疑问句:
1.在谓语是be动词的句子中,将be动词移到主词前,句尾加“”,即可构成疑问句格式:
肯:
主词+am/is/are+……
疑:
Am/Is/Are+主词+……
Ex:
肯;Itismypen.
疑:
Isitmypen
练习ismysister.(写出它的疑问句)
isahandsomeboy.
动词开头的一般疑问句,可用Yes或No回答,而答句中的主词需要用代名词(I/She/He/They/We等)代替.
格式:
肯:
Yes,主词+am/are/is.
否:
No,主词+am/are/is+not.
Ex:
Isthatmanyourfriend
答:
Yes,heis/No,heisnot.
练习:

肯定回答:

特殊疑问句:
疑问词5个W:
、Who、Where、When、What、Why

变疑问,往前提,句末问号莫丢弃。
变否定,更容易,be后not莫忘记。
疑问否定任你变,句首莫迟疑。
