二、动词遇到单数第三人称时的表示方法
一般现在时的句型
1.肯定句构成:
主语+动词(注意人称变化)+其它成分
Ihaveadog.Welikethelittlecat.Shesingswell.
2.否定句构成:
行为动词的否定句:
主语+助动词(do/does)+not+动词原形+其它成分
Hedosen'thaveadog.Heisn'tyoung.Wedon'tlikethelittlecat.
(借助于助动词do)Shedoesn'tsingwell.(借助于助动词does)
3.一般疑问句:
A.行为动词的一般疑问句:
助动词(do/does)+主语+动词原形+其它成分
Doyoulikeit?
Yes,Ido./No.Idon't.Doeshe(she)/itlikeit?
Yes,he(she)does./No,he(she)doesn't.
Dothey/welikeplayingbasketball?
Yes,they/wedo.No,they/wedon’t.
B.动词BE的一般疑问句Am/Is/Are+主语+其它成分
AreyouateacherYes,Iam./No,Iamnot.
Aretheystudentsofyourschool.Yestheyare/Notheyaren,t.
4.特殊疑问句:
特殊疑问词+一般疑问句
Whatdoyoulike?
Whatdoyoudo?
Howoldareyou?
Whereareyoufrom?
Whatclassareyouin?
Howdoyouspellit?
_这里所说的行为动词,指的是除be动词、情态动词和助动词之外的全部动词。
难点
1:
主语不是第三人称单数的句子,肯定句:
主+动词+宾语;否定句:
主+don’t+动词+宾语;疑问句:
Do+主+动词+宾语?
Yes,I/they/wedo.No,I/they/wedon’t 难点
2:
如果主语是单数第三人称,情况比较复杂.肯定句:
主+动词(s)+宾语;否定句:
主+doesn’t+动词+宾语; 疑问句:
Does+主+动词+宾语?
Yes,she,he/itdoes.No,she/he/itdoesn’t/ 难点
3:
当主语为第三人称单数he,she,it时,词形有变化:
通常有三种变化:
1、多数在动词后加s 如play—plays like—likes,read-readssing-singsdance-danceslook-looks
2、以s,x,sh,ch,o结尾的动词加es go—goes watch-watchesdo-does
3、以辅音字母加y结尾,把y改i再加es study—studies (这种变化与名词的单数变复数有点相像)
那么,什么情况下用行为动词的一般现在时呢?
当这个动作经常发生或表示习惯性的动作时,通常用一般现在时,它经常与表示频度的时间状语连用,如,当句子中有everyday,everyyear,onSunday,inthemorning,often,sometimes,usually,atoneo’clock,等词时,用一般现在时。
轻松击破:
只要记住下面的顺口溜,什么时候在动词后加S就易如反掌了。
我老大,你老二,他,她,它是老三;我们,你们和他们,能量可是不简单。
只有老三能量低,加个S保平安。
不过不要太贪婪,does加上S减,这样一来才安全.一写出
在一般现在时中,当主语是单数第三人称时,行为动词的形式是在词尾加-s或–es具体方法如下:
1.一般情况下,直接加-s
eg.works,plays,rains,sees
2.以sh,ch,s,x或o结尾的词后加–es
eg.washes,teaches,fixes,does,goes
3.以辅音字母加-y结尾的,先把‘y’改成‘i’,再加-es
eg.studies,flies,carries
注意:
动词加-s以后的读音.
动词加-s后的读音
1.在[p][t][k][f]等清辅音后,发清辅音/s/
eg.helps,works,likes,hates,laughs
2.在浊辅音和元音后,发浊辅音/z/
eg.drives,cleans,plays
3.在[s][z][∫][t∫][[dʒ]后,发/iz/
rises,wishes,teaches,urges
4.在[t][d]后,发/ts//dz/
eg.fits,sets,needs
5.其他情况下发[z]
eg.plans,cries,shows
