4、.They are students.（他們是學(xué)生）3. she can play chess.(她能夠下象棋）4.

5、為三單，其后動(dòng)詞s添”。何謂第三人稱(chēng)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(dòng)詞第三人稱(chēng)單數(shù)變化規(guī)則動(dòng)詞第三人稱(chēng)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：looks,

6、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(shí)的句子轉(zhuǎn)換當(dāng)句子中有be動(dòng)詞或情態(tài)

7、動(dòng)詞時(shí)，則把be動(dòng)詞或情態(tài)動(dòng)詞(can,could等等)提到主語(yǔ)的前面變成一般疑問(wèn)句;在be動(dòng)詞或情態(tài)動(dòng)詞后面加not變成否定句.例：陳述句：She is a student.一般疑問(wèn)句 Is she a student?否定句 She is not a student.陳述句：I can swim.一般疑問(wèn)句 Can you swim?否定句 I can not swim.當(dāng)句子中即沒(méi)有be動(dòng)詞，也沒(méi)有情態(tài)動(dòng)詞時(shí)，則在主語(yǔ)前加助動(dòng)詞do (you,以及復(fù)數(shù)), does（單數(shù)she,he,it）變成一般疑問(wèn)句；在主語(yǔ)后謂語(yǔ)動(dòng)詞前加助動(dòng)詞dont（I,you,以及復(fù)數(shù)), doesnt（單數(shù)s

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