2017届高考英语一轮复习课件：Unit12 Culture Shock(北师大版)

　　题型突破栏目链接现在分词考点综述语法专题一、现在分词的定义语法专题　现在分词是动词的另一种非谓语形式。它兼有动词、副词和形容词的特征，可以带宾语或受状语修饰。现在分词和宾语或状语一起构成现在分词短语。二、现在分词的基本形式语法专题现在分词由动词原形加词尾－ing构成，与动名词形式相同。其否定形式是在现在分词前加not构成。现在分词有一般式和完成式，及物动词的现在分词有主动语态和被动语态。其形式如下现在分词及物动词write 不及物动词go 主动语态被动语态一般式 writing being written going 完成式 having written having been written having gone 三、现在分词的句法功能语法专题　现在分词在句中可以作定语、表语、宾语补足语或状语。 ·The girl standing there is my sister.(作定语) ·The news was disappointing．(作表语) ·They kept me waiting for a long time.(作宾语补足语) ·Being ill，she didn't go to school today.(作原因状语) ·Her mother died in 1969，leaving her with four younger brothers and sisters.(作结果状语) 四、现在分词的考点语法专题 1．现在分词作状语。现在分词作状语，分词必须和句中的主语含有逻辑上的主谓关系。作状语时可以表示时间、原因、结果、条件、让步、行为方式、伴随情况等，并可以转换成相应的状语从句。 ·Not knowing her telephone number (＝Because I didn't know her telephone number)，I couldn't ring her up.(表原因) ·Walking in the street (＝While I was walking in the street)，I saw a friend of mine.(表时间) 语法专题 ·He sat at the table reading China Daily.(表伴随) ·The child fell，striking his head against the door and cutting it.(表结果) ·Turning to the right (＝If you turn to the right)，you will find the place you want.(表条件) 注意：如果分词表示的动作完成后，谓语表示的动作才发生，此时分词用完成式。 ·Having come to a decision，we immediately set to work.(做出决定后，我们立即开始了工作。) 语法专题 2．现在分词与动词不定式作结果状语的区别。现在分词作结果状语表示意料之中的结果，而动词不定式作结果状语表示意料之外、没有想到的结果。 ·The parents died，leaving him an orphan.(意料中之结果) ·He hurried to the station，only to find the train had left.(意料之外的结果) 3．现在分词与过去分词的区别。 (1)语态上的不同：现在分词表示主动的意思，而过去分词多表示被动的意思。语法专题
