動詞不定式?jīng)]有人稱和數(shù)的變化。

動詞不定式具有名詞、形容詞和副詞的特征，因此可在句中作主語、賓語、賓語補足語、定語和狀語等。2.動詞不定式的用法為了避免句子“頭重腳輕”，往往用it代替不定式作形式主語，而將不定式放在后面作真正的主語?！咀髦髡Z】：一般位于句首，謂語動詞用單數(shù)形式。例：學外語很有用。

It’sveryusefultolearnforeignlanguages.【浙江衢州中考】It’sabadhabitto____whatyoucandotoday

untiltomorrow.A.writedown

B.talkaboutC.worryabout

D.putoff【作賓語】：主語+謂語+todo

不定式常出現(xiàn)在一些及物動詞后，構成動詞短語。如：wanttodo,plantodo,agreetodo,learn

todo等。另一種是“及物動詞+疑問詞+帶to的不定式”。例：他教我如何使用手機。Hetaughtmehowtousemobilephone.

與特殊疑問詞連用：放在what,which,where,when,who,how等詞之后。他不知道怎樣回答這個問題。

Hedon’tknowhowtoanswerthisquestion.【山東菏澤中考】—Haveyoudecidedwhen____?—Yes,tomorrowmorning.A.willyouleave

B.areyouleaving

C.toleave【作賓語補足語】常接不定式作賓語補足語的詞有tell,ask,want,teach,allow,promise,order,advise,expect,wish,invite,encourage

等。例：他們請他在宴會上唱一首流行歌曲。Theyaskedhimtosingapopsongattheparty.一感(feel)二聽(listento,hear)三讓(let,make,have)四看(lookat,see,watch,notice)，半幫助(help)(即在動詞help后面作賓語補足語時，to可有可無)”。help后的不定式可省略to，也可以帶上to。例：我哥哥經(jīng)常幫助我做家務。

Mybrotheroftenhelpsme(to)dothehousework.【吉林長春中考】Igotomygrandparents’home______withtheirhouseworkeverySunday.A.help B.helpedC.tohelp D.helping

在感官動詞feel,hear,see,watch,notice,listento,lookat之后接不帶to的動詞不定式作賓語補足語。例：半小時前我看見她離開了。

Isawherleavehalfanhourago.【作表語】一、主語是不定式(表條件)；表語也是不定式(表結果)例：工作意味著謀生。

Toworkmeanstoearnaliving．二、動詞不定式做表語常用于以下結構：Myjob/dream/goal/aimis…例：他的夢想是在不久的將來出國學習。Hisaimistostudyabroadinthenearfuture．【作定語】：不定式作定語應放于被修飾詞之后。例：我想吃點東西。

Iwanttohavesomethingtoeat.【作目的狀語】動詞不定式可表示某一動作或狀態(tài)的目的，位于句首或句尾。例：她提高了她的聲音，以便聽得更好。

Sheraisedhervoicetobeheardbetter．

他將去車站見他的朋友。
