分词是什么
英语上的分词分为现在分词和过去分词.
现在分词和过去分词主要差别在于：现在分词表示"主动和进行",过去分词表示"被动和完成"(不及物动词的过去分词不表示被动,只表示完成).分词可以有自己的状语、宾语或逻辑主语等.
1、 分词作状语分词在句子中作状语,可以表示时间、条件、原因、结果、让步、伴随等.
分词在句子中作状语,使用何种分词,要取决于分词与句子主语的关系：主谓关系用现在分词,动宾或被动关系用过去分词.
（1）现在分词The students went out of the classroom,laughing and talking.
（2）过去分词Accompanied by his friend,he went to the railway station.Given better attention,the plants could grow better.
2、"while ( when,once,until,if ,though等连词)＋分词"结构现在分词或过去分词作状语时,有时可以在分词前加while,when,once,although,until,if等连词.
When leaving the airport,she waved again and again to us.While waiting for the train,I had a long talk with my sister about her work……
Once recovered,he threw himself into his work and made every effort to do it well.
Although working very hard,he failed to pass the final exam.If translated word by word,the passage will be difficult to understand.
3、分词作定语分词作定语时,单个的分词通常放在被修饰的名词之前,分词短语一般置于所修饰的中心词后面.现在分词修饰的是发出该动作的名词(即与名词有主谓关系),过去分词修饰承受该动作的名词(即与名词是动宾关系).

This is really an exhausting day to all of us!

After a night spent in excitement and sleeplessness,I forced myself to take a long walk along the beach the next day.

4、分词作宾语补足语现在分词在see,watch,hear,observe,notice,feel,find,glimpse,glance等感官动词和look at,listen to等短语动词以及have,keep,get,catch,leave,set,start,send等使役动词后面与名词或代词构成复合宾语,作宾语补语的成分.
5、分词作表语分词作表语通常看作形容词来用.现在分词表示主语的性质,而且主语多为物；过去分词表示主语的感受或状态,主语多为人.
