9、h my English. 他经常帮助我学英语。（help这个动作经常发生often；故用一般现在时）英语中常用的时态有：一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时等等。2. 语态：在英语语言中，语态主要讨论句子主语与行为动词的关系。语态有两种：主动语态和被动语态。 主语是动作的发出者(执行者)为主动语态；如： The tall boy often hits his classmates（主语boy是谓语动词hit的发出者）。 主语是动作的接受者（承受者）为被动语态。汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用：助动词b

10、e + 及物动词的过去分词构成如： Chinese is spoken by the most people in the world（主语Chinese是谓语动词speak的接受者）。2. 语态与时态的关系：在任何一个英语句子中都同时存在语态时态，他们是分析一个英语句子的两个主要元素。如： He is looking after his sister at home.（此句为现在进行时的主动语态结构） He is being looked after well by his parents. （此句为现在进行时的被动语态结构）说明：我们以前所学的各种时态的结构其实都时主动语态的各种时态结构。

11、二、被动语态最基本的句型结构是： be +及物动词过去分词 说明：、be 有时态，人称和数的变化。、被动语态中的谓语动词必须是及物动词；因为被动句中的主语是动作的承受者，某些短语动词如look after, think of, take care of, work out, laugh at等，也可用于被动语态。三、被 动 语 态 的 使 用1.当不知道或没有必要指出动作的执行者时，常用被动语态，这时往往不用by 短语。 “Mr. White, the cup with mixture was broken after class. ”(只是告诉老师杯子坏了，不知是谁弄坏的，或不想说出谁弄坏的

12、)。 2.突出或强调动作的承受者，如果需要说出动作的执行者，用by 短语。如：The cup was broken by Paul. 3.当汉语句子的主语既不是动作的执行者，也不是动作的承受者时，这时常用in + 名词作状语，而代替 by 短语。 如：These cars were made in China.四、主动语态变被动语态的变法：主动语态与被动语态之间如何转换1.把主动语态的宾语变成被动语态的主语。 2.把主动语态的谓语变成被动语态的be + 过去分词，时态要与原句保持一致。 3.把主动语态的主语变为介词by 的宾语，放在被动语态里谓语动词之后，by 短语可以省略。如果原句主语是地点

13、名词，在被动语态中用in + 地点名词作状语。 口诀：宾变主，主变宾，谓变be done ,时不变，数格必须随被变。五、一般现在时的被动语态：am /is/ are +done如： Tea is grown in Hangzhou. 杭州种植茶叶【课堂变式】The room every day. You can live in now. A. cleans B. is cleaning C. is cleaned D. has cleaned【解析】 根据句意“房间每天都打扫，你现在可以居住了”，可知，房间是每天被打扫，所以要用一般时态的被动语态，所以选择答案C。五、练评（包含“考点链接” 应

14、用探究 6分钟）根据汉语意思完成下列句子，每空一词。1. 他的新手机是美国制造的。 His new mobile phone _ _ _America.2. 这台电视机是由工厂的工人们制造的。 The TV set is _ _ the workers in the factory. 3. 这些瓶子是塑料做的。 These bottles are _ _ plastic.4. 面包是小麦做的。 The bread is _ _ wheat. 5. 这种沙拉是用香蕉和苹果做的。 The salad is _ _ bananas and apples.补全对话 根据对话内容，填写适当的话语，使对话完整、正确。（每空词数不限）A: What is this?B: Its a plike.A: 1. _?B: Its made of steel and iron.A: 2. _?B: Its used to fly like a plane and ride like a bike.A: 3._?B: I think its strange.A: 4._?B: Yes, I want to try it.A: OK, _.B: All right.【教学反思】
