1、1.动词-ing形式的构成：是在动词末尾加-ing 形式构成，因此又叫动词的-ing 形式。如：do-doing,be-being,ask-asking,etc.否定形式：not+-ing 构成2.动词-ing形式不能单独作谓语，没有人称和数的变化，但可以有自己的宾语和状语，还有时态和语态的变化。-ing 形式-ing 形式主要考查其在句子中作定语和状语的用法European football is played in 80 countries,_ it the most popular sport in the world.A.making B.makes B.C.made D.to mak
2、e解析Making it the popular sport in the world为现在分词短语作结果状语，这类分词短语常放在句子的后面。如：His parents died,leaving him an orphan.动名词：在句子中起名次作用，可作主，宾，表，定的成分。动名词的形式主动形式被动形式一般式doingbeing done完成式having donehaving been done1 The ving form used as subject:It is necessary to get water from wet to dry place.Getting water fr

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

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
