動詞不定式是非謂語動詞的一種，它沒有人稱和數的變化，在句子中不能獨立作謂語。肯定式：to+

動詞原形否定式：notto+

動詞原形(to是不定式符號，無意義，有時可以不帶)動詞不定式的基本形式動詞不定式的用法

動詞不定式具有名詞、形容詞和副詞的特征。因此在句中可以做主語、表語、賓語、賓語補足語、定語和狀語。功能：

作主語

todo作主語，常放句尾，用it作形式主語1.Itis+adj.+(of/forsb.)+todosth.It’sgoodtoseeyou.

離開時請記得關好燈。動詞不定式作賓語的注意事項（2點）2．不定式作賓語時，如帶有賓語補足語，則要把不定式放到后面，用it作形式賓語，構成“主語+動詞+it+賓補（形容詞、名詞）+不定式”結構。如：

Hefounditverydifficulttogettosleep.

他發現很難入睡。作賓語補足語：(v.+sb.+todo)Sheasked

me

tohelpher.Theteachertold

him

tocomeontime.Edison’smothertaught

tocry.JimtoldLiMingtogivehisbestwishestoeverybody.Heletmedoitagain.注意A.有些動詞后面的不定式不帶to，如feel（一感）hear,listento（二聽）make,have,let（三讓）

see,watch,notice,observe（四看）.但變為被動語態時要加to.Iheardthemsingapopsong.Theywereheard

to

singapopsong.Wewatchedthemplayfootball.注意

B.

動詞不定式的否定式只須在to

前加

not.不帶to的不定式則在動詞前加not.

Myfatherdecidednottotakeupthejob.Theteachertoldusnottobelateagain.Mymotherletmenotdoitbymyself.注意C.帶疑問詞的動詞不定式在to

前加疑問詞。不定式與疑問詞連用,常用動詞有:askknowlearnteachtellunderstand等。Mr.Linwillteachushowtousethecomputer.Canyoutellmewheretogetthebook?構成形式作用例句who

whatwhichhow等＋todowherewhen主語Whentostarthasnotbeendecided.表語Thequestioniswheretogo.賓語Idon’tknowhowtodoit.賓補Nobodytolduswhattodo.注意D.作簡短回答或避免不必要的重復時，動詞不定式常常省去to后面的動詞，只保留to

。A:Wouldyouliketocometomyparty?Marywantedtousemybike,butIaskedhernotto(usemybike).B:Yes,I’dloveto(cometoyourparty).Mary想用我的自行車，但我叫她別用。感官動詞see,watch,notice,hear,feel

感官動詞后既可跟不帶to的不定式作賓補，也可跟v-ing作賓補，前者表示動作的全部過程已結束；后者表示動作正在進行。
