3、ed,to be rebuilt,语法精析,语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者说动作不是由主语而是由其他人完成的，则用被动语态。 被动语态的构成是：助动词be动词的过去分词。,一、各种时态的被动语态 1.各种时态的主、被动语态的构成,2.注意事项 (1)“be过去分词”并非都是被动语态，系动词 be，feel，seem，look等词后面的过去分词已转化为形容词，作表语用，构成系表结构，表示某种状态。 Im interested in mathematics.

4、我对数学感兴趣。 He seems unsatisfied with his work. 他似乎对自己的工作不满意。,(2)英语中有一些短语常以被动形式呈现，但表示主动意义。 She is usually dressed in white. 她通常穿白色衣服。 The boy was seated by the window. 小男孩坐在窗户旁。 (3)“get过去分词”也表被动。 We got separated when we entered the big hall. 我们进入大厅时被挤散了。,(4)某些情况用主动语态来表示被动含义。 read，write，act，iron，burn，c

5、ut，draw，drive，sell，wash，clean，wear，open，cook，lock，shut，dry，eat，drink等动词，用来说明主语的性质特征而不强调被执行者的动作时，用主动形式表达被动意义，且常与not，hardly，well，easily，badly，nicely等副词连用。 The door doesnt open easily.门不容易打开。 Bikes of that kind sell well.那种自行车好卖。,某些表示“发生”的动词(短语)，如happen，take place，occur，break out，burst out等没有被动语态，但其意义中

6、包含被动概念。 The war broke out in 1937.战争爆发于1937年。 Heavy rains occurred during a summer monsoon. 暴雨出现在一个夏季季风期。,(5)不能用于被动语态的及物动词或动词短语： fit，have，wish，cost，agree with，arrive at/in，shake hands with，succeed in，suffer from，take part in，walk into，belong to等。 This key just fits the lock.这把钥匙只适合于这把锁。 Your story a

7、grees with what has already been heard. 你的故事与听说的相符合。,二、不定式的被动形式 动词不定式具有动词的特点，可以有自己的宾语和状语，还有时态和语态特征。当不定式的逻辑主语是其动作的承受者时，不定式一般要用被动形式。 1.不定式的被动形式的构成,2.用法 (1)作主语 Its a pity to be kept in the house in such fine weather. 在这样的好天气里被关在家里真是遗憾。 (2)作宾语 The boy asked to be given an opportunity to try again. 那男孩要求

10、e has a family to support.(to support与family是动宾关系，与he是主谓关系。) 他要维持一个家庭。 注意：若句子的主语不是不定式的逻辑主语时，不定式要用被动式。 Ill go to the post office.Do you have a letter to be posted? (不定式的被动语态作定语，you不是post动作的执行者。) 我要去邮局，你有信要寄吗？,(2)在某些“形容词不定式”作表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，har

11、d，difficult，important，impossible，pleasant，interesting等。 That question is difficult to answer. 那个问题不容易回答。,(3)在there be.句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人；用被动形式作定语，重点在物。 There is no time to lose/to be lost.(用 to lose可看成for us to lose；用to be lost，谁 lose time不明确。) 没有可以失去的时间了。,高考链接,.单句语法填空,1.My washing m
