Jane looks after the cat.如果想要说“这些歌曲受到孩子们的喜爱”、“这只猫由简照看”，该：怎样用英语表达呢？这两组句子表达的重点很不一样：第一组句子侧重“人”，即某人怎样；而第二组句子侧重“事”，即某事如何。所以，第一组句子使用主动语态，而第二组句子使用被动语态。被动语态的表达有固定的结构。我们先来对比以下两组句子：Children lovethese songs. 主动语态(动作执行者)（动作） （动作接受者）These songs are lovedby children 被动语态(动作接受者）（动作）(动作执行者)Jane looks after the cat. 主动语态(动作执行者)（动作）（动作接受者）The cat is looked after by Jane. 被动语态（动作接受者）（动作） (动作执行者)从以上对比我们可以看出被动语态的构成和用法。四、精讲规则1.被动语态的构成被动语态中动作接受者作句子主语，动作执行者置于句末，用by连接，有时可以省去不用。谓语动词由“be+动词的过去分词”构成，一般现在时被动语态的结构为：主语（动作接受者）+is/am/are +动词的过去分词+（by+动作执行者）被动语态的句型总结如下：肯定句：主语+be+过去分词+（by ）否定句：主语+be not+过去分词+（by ）一般疑问句：Be +主语+过去分词+（by ）?特殊疑问句：特殊疑问词+ be +主语+过去分词+（by ）?下面我们来看一些具体例子-Is the boy called Jack?这个男孩儿叫杰克吗？- Yes, he is. / No, he isnt.是的。/不是。The baby is not looked after by his father .这个小孩儿不由他父亲照顾。-What languages are spoken inCanada?加拿大说什么语言？-French and English.法语和英语。2.被动语态的用法同学们会问，什么时候使用被动语态呢？一般说来，被动语态用于以下几种情况：1）要表达“被”、“受”、“遭”、“让”之类的语义。如：教师很受尊敬。 Teachers are well respected.这孩子很招人喜爱。 The child is well loved by people.2)强调动作接受者。如：他远近闻名。 He is known far and wide.3)不知道或没有必要指出动作的执行者。如：房子每天都有人打扫。 The room is cleaned every day.总的说来，判断该不该用被动语态主要是看主语是否为谓语动词的行为对象。五、练评（包含“考点链接” 应用探究 6分钟）一般现在时态的被动语态专项练习一、单项选择（ ）1Usually puters _ to search the Internet.A. useB. are usingC. are used（ ）2Trees and flowers _ every year to make our country more beautiful.A. cleanB. cleansC. are cleaned（ ）3Today Chinese _ by more and more people around the world.A.speakB.is spokenC. are spoken（ ）4Make sure all the lights _ when you leave the room.OK, I will.A.turn offB. are turned offC. are turned on（ ）5The baby _by his grandma.A. is looked afterB. are looked afterD. look after二、用动词的正确形式填空1) The Great Wall _ (know) all over the world.2) A storm _ often _ (follow) by a calm.3) Some newspapers _ (publish) once a week.4) English is very popular. It _ widely _ (use) in many fields.5) Plato was a great thinker. The modern world _ still _ (influence) by his thoughts about life, education and so on.三、把下列句子改为被动语态1.They play football on Sunday._2.Lucy does the homework in the evening._3.They often use puters in class._4.We make these machines in Beilun._5.People speak English as the first language inUK._四、阅读理解Teenagers should be allowed to work.
