6、ng 例如：Its no use going there today;he wont be at home.Its a waste of time arguing about it.而在Its important/necessary/advisable/essential/fitting 这类句型中，只能用不定式，如：Its important to learn foreign languages.2.在allow,advise,forbid,permit后直接跟动名词作宾语，如果有名词或代词作宾语，则构成“allowadviseforbidpermit 名词代词不定式（宾语补足语）”之形式。

7、如：We dont allow smoking hereWe dont allow anybody to smoke here3.动词need,require,want意为“需要”时，后跟动名词的主动式或不定式的被动式作宾语，意义没有区别。如：The window needsrequireswants cleaningto be cleaned4.在begin,continue,love,like,hate,prefer,intend,start 后用动名词和用不定式作宾语均可，意义没有多大区别。5.动词forget,go on,mean,regret,remember,stop,try,be

8、 used to,cant help后跟动名词和跟不定式区别较大，须注意:forget,regret,remember后跟动名词，动名词表示已经发生的动作；后跟不定式表示将要发生的动作。go on doing 继续做原来做的事go on to do 接着做另一件事mean doing 意味着要做某事mean to do 想要做某事stop doing 停止做某事stop to do 停下来（别的事）开始做某事try doing 试着做某事try to do 努力做某事be used to doing 习惯于做某事be used to do 被用来做某事cant help doing 禁不住做某

10、意为“记得曾经告诉过我”。怎么判断是动名词还是现在分词呢？方法一：My job is teaching.Teaching is my job.The boy is sleeping.Sleeping is the boy.A girl is dancing.Dancing is the girl.找出右边成立的句子。动名词现在分词现在分词在做表语的时候：作表语（1）动名词My job is teaching.=Teaching is my job.Her full-time job is laying eggs.=Laying eggs is her full-time job.作表语（2）现

11、在分词The play is exciting.Exciting is the play.The story he told us was very interesting.Interesting was the story he told us.方法二：在做定语的时候：A drinking cupA cup for drinkingThe sleeping boyA boy for sleepingA cooking panA pan for cooking找出右边成立的句子。动名词动名词现在分词现在分词作定语表示动作。如果是单词，放在被修饰的名词前；如果是短语，放就放在被修饰的名词之后。动

12、名词作定语表示性质或用途。总结：现在分词做宾补的时候，表示正在进行的动作。e.g.I saw the boy crying sadly.V+sb.+doing sth.像这样的单词还有：make、let、have、look at、listen tosee,hear,feel,watch,notice,observe,find,leave等。能跟现在分词作宾语补足语的常见动词有这些，看看有什么好方法可以将它们记住：make,let,have,look at,see,watch,hear,listen to,notice,feel.对了，用“三让、三看、两听、注意感觉”。多简单！1.It took
