4、女孩） 2。They are students.(他們是學生）3. she can play chess.(她能夠下象棋）4. They can sing。（他們能唱歌）(2）含實義動詞的謂語動詞.當主語為非第三人稱單數(shù)，謂語動詞用原型。當主語為第三人稱單數(shù)，謂語動詞用第三人稱單數(shù)形式。Eg1。We often get up early in the morning.Eg2。My father often gets up early in the morning。（3） 談?wù)劇爸髡Z為三單，其后動詞s添在含實義動詞的一般現(xiàn)在時中，當主語為第三人稱單數(shù)時，謂語動詞要用第三人稱單數(shù)形式。可以簡單敘述

5、為“主語為三單，其后動詞s添”.何謂第三人稱單數(shù)?用一句話概括就是“非你、非我、非復(fù)數(shù)，如he, she， it, my father, my mother, my sister， our English teacher， Tom, Mike， Liu Jia， China, my book, etc.Eg3。He sometimes goes to school by bike。Eg4。My father works in the hospital as a doctor。(4）動詞第三人稱單數(shù)變化規(guī)則動詞第三人稱變化的規(guī)則與可數(shù)名詞復(fù)數(shù)變化的規(guī)則相同.規(guī)則一、一般在詞尾加-s。如：look

6、s， puts. reads， sees, skis等。規(guī)則二、以-o, s, x， sh, -ch結(jié)尾的加es.如：goes， does, misses， passes, mixes， fixes， pushes, wishes, watches, teaches,等。規(guī)則三、以輔音字母加y結(jié)尾的,變y為i，再加-es。注意一定是輔音字母加y才變，若是元音字母加y,則直接加-s。如：flyflies,trytries,fryfries，copycopiesbuybuys，enjoyenjoys,playplays，saysays,paypays四一般現(xiàn)在時的句子轉(zhuǎn)換當句子中有be動詞或情態(tài)動

7、詞時,則把be動詞或情態(tài)動詞（can，could等等）提到主語的前面變成一般疑問句；在be動詞或情態(tài)動詞后面加not變成否定句.例：陳述句:She is a student。一般疑問句 Is she a student?否定句 She is not a student.陳述句：I can swim。一般疑問句 Can you swim？否定句 I can not swim.當句子中即沒有be動詞，也沒有情態(tài)動詞時，則在主語前加助動詞do （you，以及復(fù)數(shù)）, does（單數(shù)she，he,it)變成一般疑問句；在主語后謂語動詞前加助動詞dont（I，you，以及復(fù)數(shù)）, doesnt（單數(shù)sh

8、e，he，it)變成否定句，助動詞后的動詞要變成動詞原形。例：陳述句：We get up at 7:00 every morning.一般疑問句Do you get up at 7:00 every morning?否定句We dont get up at 7:00 every morning。陳述句:She has a little brother.一般疑問句 Does she have a little brother？否定句 She doesnt have a little brother.六、練習鞏固1.寫出下列動詞的三單形式go_ catch_ brush(刷）_ wash_do_
