9、央语。（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。1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 疋谓语动词 hit 的发出者）。2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 be +及物动词的过去分词构

10、成女口： Chin ese is spoke n 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冋时存在语态时态，他们是分析一个英语句子的两个主要元素。如： He is look ing 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 paren ts.（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。二、被动语态最

11、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, thi nk of, take care of,work out, laugh at等，也可用于被动语态。26三、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）。2. 突出或强调

12、动作的承受者， 如果需要说出动作的执行者，用 by 短语。女口： 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。女口： These cars were made in Chi na.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，时态要与原句保扌寸致。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名词，在

13、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 +do ne女口： Tea is grown in Han gzhou.杭州种植茶叶【课堂变式】The roomevery day. You can live in now.A. clea nsB. is clea ningC. is clea nedD. has clea ned【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Co五、练评（包含“考点链接”应用探究 6 分钟）根据汉语意思完成下列句子，每空一词。71. 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:
