不定式短語可以作賓語，以下動詞后，跟不定式作賓語eg.1)Hewantedtogo.

agree,decide,expect,fail,help,hope,manage,offer,plan,prepare,pretend,promise,refuse,wish▲(構(gòu)成"V.+todo"的形式)Ifinditinterestingtoworkwithhim.如果還帶有賓語補(bǔ)足語，往往把不定式賓語放在賓語補(bǔ)足語之后，而用it作形式賓語類似的動詞還有

▲(構(gòu)成"主語+V.+it+賓補(bǔ)+todosth."的形式)feel,think,consider,make,believe(3)作賓語補(bǔ)足語eg.Heaskedmetodotheworkwithhim.在feel,hear,listento,lookat,notice,observe,see,watch,

have,let,make

等詞后的補(bǔ)足語中，不定式不帶to。但是這些句子如果變成被動結(jié)構(gòu)時，就必須帶to。Eg.Ioftenhearhimsingthesong.

Heisoftenheardtosingthesong.注意

allow,ask,advise,encourage,expect,forbid,force,get,wouldlike,order,permit,persuade,teach,tell,want,warn,wish▲(構(gòu)成“V.+Sb.+todo”的形式)②不定式動詞在介詞but,except,besides

后面時，如果這些介詞之前有行為動詞do的各種形式，那么，這些介詞后的不定式不帶to,否則要帶to。Eg.1)Shecoulddonothingbutcry.2)Ihavenochoicebuttogo.注意

(4)作定語

Eg.Ihavesomebooksforyoutoread.①作定語的不定式如果是不及物動詞，不定式后面須有相應(yīng)的介詞。

Eg.Heislookingforaroomtolivein.

Thereisnothingtoworryabout.Pleasegivemeaknifetocutwith.注意

(5)作狀語,表示目的、原因、結(jié)果

Eg.Icameheretoseeyou.

Wewereveryexcitedtohearthenews.

Hehurriedtotheschooltofindnobodythere.(目的)(原因)(結(jié)果)

目的狀語還可以用inorderto

或soasto來表示。

Eg.1)Inordertopasstheexam,heworkedveryhard.2)Weranallthewaysoasnottobelate.(6)作表語。Eg.Myjobistohelpthepatient.

Step5不定式的省略1.有些固定搭配中只能跟動詞原形

wouldrather,hadbetter,can’tbut,can’tchoosebut,can’thelpbut,donothingbut,whynot,Ican’thelpbutadmirehimforhiscourage.Translation:我不得不佩服他的勇氣。1)omit“to”2)omit“do”Intheend,theenemyhadnochoicebuttosurrender.

see,watch,observe,notice(4)have,make,let,(3)hear,listento(2)feel(1)Heoftenmadehissister_____(cry),butthistimehewasmade______(cry)byhissister.

2.不定式作下列動詞的賓補(bǔ)時省to
