I am like this animal because I am strong and intelligent. I like water, and I like to eat vegetables. Grammar Focus: 　 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。 Many people speak English. 谓语：speak 的动作是由主语 many people 来执行的。 　 被动语态表示主语是动作的承受者，即行为动作的对象。English is spoken by many people. 主语 English 是动词speak 的承受者。 　　动态和被动态指的是动词形式，是词法概念；而主动句和被动句则指的是句子结构，从而是句法概念。所谓主动句就是由主动态动词 (词组) 作谓语动词的句子，而被动句则是由被动态动词 (词组) 作谓语动词的句子。 Grammar Focus: 被动语态的构成 　　被动语态由 “助动词 be＋及物动词的过去分词” 构成。人称、数和时态的变化是通过 be 的变化表现出来的。现以 teach 为例说明被动语态在各种时态中的构成。 　　一般现在时：am／is／are＋taught 　　一般过去时：was／were＋taught 　　一般将来时：will／shall be＋taught 　　现在进行时：am／is／are being＋taught 　　过去进行时：have／has been＋taught 　　现在完成时：have／has been＋taught 　　歌诀是：被动语态 be 字变，过去分词跟后面。　 Grammar Focus: 被动语态的用法:(1) 不知道或没有必要说明动作的执行者是谁。Some?new?computers?were?stolen?last?night.?一些新电脑在昨晚被盗了。(不知道电脑是谁偷的)This?book?was?published?in?1981. 这本书出版于1981年。 (2) 强调动作的承受者，而不强调动作的执行者。The?window?was?broken?by?Mike. 窗户是迈克打破的。This?book?was?written?by?him. 这本书是他写的。Eight?hours?per?day?for?sleep?must?be?guaranteed. 每天8小时睡眠必须得到保证。歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。 Make a survey writing Pairwork: A: Recycling paper is really easy.
