3、ry,better,the first,the next,the last,the best,too much,too little,not enough等。Its so nice to hear your voice.动名词与不定式都可作主语或宾语。动名词表习惯、笼统的动作;不定式表具体、一次性动作;分词不能作主语或宾语。5一、非谓语动词作主语或宾语(1)用于表示事物的特征、特点,表示客观形式的形容词,如 easy,hard,difficult,interesting,impossible等,常用It is+adj.+for sb to do sth句型。Its very hard for

5、谓语动词作主语或宾语2.只接动名词作宾语的动词。如:admit,suggest,imagine,avoid,risk,appreciate,delay,consider,excuse,fancy,escape,forbid,finish,mind,miss,practice,resist,bear,stand 等。3.只接不定式作宾语的动词。如:agree,refuse,offer,promise,decide,determine,intend,manage,fail,hope,expect,long,wish,tend,desire,plan,pretend 等。4.有些动词是既可以接动名词
6、作宾语,又可以接不定式作宾语,但意义不同。如:remember,stop,mean,regret,go on,forget等。5.need,require,want+doing(=to be done)主动形式表被动意义。8一、非谓语动词作主语或宾语6.注意:有的短语中,to是介词,而不是不定式。常见的带介词to的短语:be used to 习惯于get down to 着手做put ones mind to 全神贯注于give rise to 引起devote oneself to 献身于lead to 导致be opposed to 反对look forward to 盼望object t
7、o 反对9一、非谓语动词作主语或宾语比较:He devoted all he had to helping(help)those in poverty.The day we had looked forward to came(come)at last.Time should be made full use of to study(study)English.I object to being made fun of(make fun of).10二、非谓语动词作宾语补足语1.能接带to的不定式作宾语补足语和主语补足语的动词有:ask,tell,force,get,allow,want,wi
