12、r five years.重点语法-被动结构我们前几期已经对被动语态做了系统的归纳，今天我们再补充一些被动语态中常遇到的问题。1. 带双宾语的动词很多动词，如：give, send, show, lend 等都可以直接加直接宾语和间接宾语，因此有两种结构：A. 动词+间接宾语+直接宾语。如：She gave her sister the car.B. 动词+直接宾语+介词+间接宾语。如：She gave the car to her sister.这两个结构都可以变成被动式：A. 间接宾语变成被动式的主语。如：Her sister was given the car.B. 直接宾语变成被动式的
13、主语。如：The car was given to her sister.2. 不带 to 的动词不定式在主动结构中，hear, see, make 和 help 后面可以跟“宾语+不带 to 的动词不定式” 。但是，如果变成被动结构，to 一定要加上。如： I saw him come out of the house. He was seen to come out of the house. They made him sell them everything. He was made to tell them everything.3. 宾语补足语在一些动词后面， 直接宾语后面可以跟宾
14、语补足语， 宾语补足语通常为名词或形容词。如： They selected Bush as President. Youve made the house beautiful.在被动结构中，这些成分是主语补足语，要放在动词后面。如： Bush was selected as President. The house has been made beautiful.注意：我们学了被动语态，不要误认为所有的句子都有被动语态，下列情况就不能用于被动语态。1. 某些表示“静止状态”的动词常表示状态而不表示动作，且一般不用于进行时态，如： have , fit , cost , last 等不能用于被动
15、语态。如：I have an English dictionary. The coat fits me well. 2. 某些及物动词可以用作不及物动词，特别是后加副词(well, easily 等)时，这时用主动语态表示被动意思。常见的这类动词有：sell, write, wear, wash, open, close 等。如：These books sell well. These kind of cloth washes well.3. 由实义动词演变而来的系动词，后接形容词作表语，不可用于被动语态。这类动词有：look, feel, sound, taste, smell, appea
16、r 等。如：He looks very young. The fish tastes nice.4. 宾语是不定式或动词的-ing 形式时，不可用于被动语态。如：He hoped to see his parents in Beijing.She enjoys watching TV in the evening. 5. 宾语是反身代词或相互代词时，不可用于被动语态。如：The little boy can dress himself.We should help each other.6. 宾语是同源宾语时，不可用于被动语态。如：We live a happy life.The girl dreamed a sweet dream.
