英语动词有两种语态，即主动语态（The Active Voice)和被动语态（The Passive Voice).主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者. Bell invented the telephone in 1876.(主动语态） The telephone was invented by Bell in 1876.(被动语态） 用法：当我们不知道谁是动作的执行者，或者没有必要 指出谁是动作的执行者，或者只需强调动作的承受者时， 要用被动语态。 English is spoken in Canada. * Unit 3 1.concentration(动词） 2.design（名词） 3. opportunity（同义词） 4. experience（形容词） 5. mess（形容词） 6. reply（近义词） 7. sleepy(动词） 8. achieve（名词） 9.reality（形容词） 10.teach（过去分词） 11.important(名词) 12.succeed(名词)(反义词） concentrate designer chance experienced messy answer sleep achievement realistic taught importance success/fail 用所给单词的适当形式填空。 1.He is a ______ boy.
