2、形容词和副词的特征，在句子中可充当主语、宾语、表语、定语和状语等成分。,非谓语动词,Collecting information is very important to business men.,I want to see you this evening.,Hearing the news,he looked disappointed.,The girl standing there is my sister.,Seen from the tower,the city looks beautiful.,I saw people coming and going in the street

5、 neither,如果要说明不定式表示的动作是谁做的，可以在不定式前加一个由for 引起的短语。It is easy for the students to read.It will be a mistake for us to help you.,在“It is+形容词+of sb+不定式”结构中，形容词往往表示人物的性格和特征，如kind,silly,good,unwise,clever,wrong,right,foolish,stupid,careless,rude,impolite,bold,thoughtful,honest,bad,sensible,naughty等。在“It is
6、+形容词+for sb+不定式”结构中，形容词通常表示事物的性质，如important,possible,impossible,necessary,difficult,hard,reasonable等。,比较 It is good of you to help me with my English.你真好，帮助我学英语。(强调you的特征=You are good to help me.)It is good for you to give up smoking.戒烟对你有好处。(强调的是give up smoking这一行为=For you to give up smoking is goo

11、 arrive and the last to leave.,2 动宾关系On Sundays,he always has a lot of letters to write.星期天，他总是有许多信要写。He can find no one to make friends with.他找不到可交朋友的人。,3 同位关系某些抽象名词后面用不定式说明某种情况，陈述某种事实，如：chance机会、opportunity机会、way方式/方法、time时间、right权利、need必要、moment片刻等。We students should have the courage to face any
12、difficulty.He has no chance to explain it to you.,4 修饰关系Now it is time to begin our class.现在是上课的时间了。,注意：、不定式作定语要考虑与主语的关系，主语是不定式的逻辑主语，不定式要用主动式；反之用被动式。He has many things to do.He wants his bike to be repaired right now.,、there be句型中用主动表示说话人的行为，被动表示说话人要别人做某事。There must be something to fear.,to be feare
13、d.,点津坊由于动词不定式与其修饰的词之间往往有动宾关系，表示动作尚未发生或有可能发生，只用一般式。因此，如果该不定式的动词是不及物动词，其后应有必要的介词，这种不定式也叫反射不定式，即不定式介词结构，介词一般不可省去，如：I need a pen to write withGive me some paper to write on.There are some thing to be grateful for.She has a child to take care of.There is nothing to worry about.He has no friend to depend
