Do you know how to operate the machine?(2)用作不及物动词，意思是“运转；起作用；做手术” (3)作“手术”讲时，其后接介词onEg. The doctor is_ his mother.(4)operation (n) 手术 Her father did a major _ last week. 她父亲上周动了一次大手术。2. invent v. 发明 inventor n. 发明家 invention n. 发明物翻译：爱迪生是个伟大的发明家，在他的一生中他发明了很多东西。Edison is a great . He many during his life. Personal computers (invent) in 1976.【知识拓展】 invent, create, find & discover(1)invent “发明；创造”，指制造、发明出新事物。(2)create “ 创造；创作；创建”，强调从无到有，既可以表示创造具体的东西，也课表示创造抽象的东西。(3)find “发现；找到”强调结果。(4)discover “发现；发觉”指初次看见本来已存在但以前未被发现的事物。Exercises: 使用invent, create, find & discover填空。Columbus America but he did not explore the continent.(大陆)They looked for the bag everywhere, but in the end they didnt it. We must work hard to a harmonious society.(和谐社会) We all know that Alexander Bell the telephone.3. be used for 意为“被用于”，介词for表示用途，后接名词、代词或动名词。（1）be used by 意为“被使用”，介词by 后面接动作的执行者。 (2) be used as 意为“被当作，介词as 表示“作为”，后常接名词。Exercises: 用be used for, be used by & be used as 的适当形式填空。 English travellers all over the world. Clothes keeping warm. The box a table. Chinese the first language.【知识链接】(unit2-sectionA)Get/be used to doing sth. 习惯于做Used to do 过去常常做4、语法讲堂被动语态 英语的语态分为主动语态和被动语态两大类。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。 被动语态的结构被动语态由“助动词be + 及物动词的过去分词”构成。不同时态的被动语态的差异主要体现在助动词be的变化上，同时助动词be还要在人称和数上与主语保持一致。见下表： 时 态构 成例 句一般现在时 am /is /are + 及物动词的过去分词You are wanted on the phone.一般过去时was / were + 及物动词的过去分词The city was liberated in 1949.一般将来时 will / shall be +及物动词的过去分词The room will be cleaned tomorrow.现在进行时am / is / are + being +及物动词的过去分词The problem is being discussed.现在完成时have / has been +及物动词的过去分词The car has been mended.过去完成时had been + 及物动词的过去分词 He said the trees had been watered.含有情态动词情态动词+ be +及物动词的过去分词The computer must be repaired now. 主动语态变被动语态的方法【记忆秘诀】宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。【用法解读】把主动语态变为被动语态时，主动语态中的宾语变为被动语态中的主语；主动语态中的谓语动词变为be的适当形式 + 过去分词（时态与原句统一）； 主动语态中的主语变为介词by 的宾语，放在谓语动词之后（如果不强调动作的执行者，by短语常可省略）。变化时要注意be动词要与新的主语在“数” 和“人称”上保持一致。如：All the people laughed at him. He was laughed at by all the people.He has cleaned the windows. We cant see stars in the the day. 【知识拓展】被动语态的使用需要注意的几点:1. 在主动语态里,有动词see. hear. watch. notice. listen to. look at. make. have等的句子中，后面常常接不带to 的动词不定式作为宾语补足语，变为被动语态时，to 要补充出来。Eg：She was seen to dance with Tom in the hall.2. 有些句子中的谓语动词是不及物动词,其后接介词或副词够成短语后,作用相当于及物动词了, 变为被动语态时，不能去掉构成短语的介词或副词。Eg: My child is taken good care of by my parents. The shirt was taken off by him this morning.3. 主动形式表被动意义（1）.open. lock. write. read. sell. wash cut drive等词作为不及物动词时,它们的主语为物,可用主动形式表被动意义. Eg: The kind of shirt sells well.This orange peels easily. (2). look sound taste smell feel等系动词用主动形式表被动意义. Eg: Mooncakes taste delicious. The song sounds wonderful. (3). 在 be worth doing 中,doing 表被动意义. The topic is well worth talking about.(4). want need 等动词表需要,后面常跟v.-ing 形式表被动,相当于to be done . My bike needs repairing.= My bike needs to be repaired.(5) 当break out 、 take place 、 shut off 、 work out等动词表示“发生、关闭、制定”等意思时表主动。 The plan worked out successfully. 计划很切实可行。 An earthquake took place in Tangshan in 1976. 1976年唐山发生地震。4 习惯用法Its said that 据说Its reported that 据报道Its believed that 大家相信Its well known that 众所周知Its thought that 大家认为目标语言（TargetLanguage）四达标测评 基本题型我过关用所给词的适当形式填空1.

What do you think is the most helpful invention? 你认为什么是最有用的发明？ 1)do you think 在此处用作插入语，常置于疑问词之后，不可置于疑问词前。如：_ do you think _ _ us English?你认为谁将教我们英语_do you think our life _ _ _ in 100 years? 你认为一百年后我们的生活会是什么样？ 2)-ful构成的形容词：carecareful wonder wonderful use useful forget forgetful 2. I think it would be better to have 我认为拥有将是更好的。 Its better (for sb.) to do sth. 意思是“（某人）最好做某事”， it 为形式主语，动词不定式短语为真正的主语。如： It is better for you to walk to school. =You _ _ walk to school.3.Id like to have a radio because I could listen to music all day.我想带一个收音机因为我能整天听音乐。1) all day=the whole day eg:I study for the final exam all day/the whole day.2) because引导原因状语从句。辨析because，since, as （1） 关于 because：语气最强，表示直接原因，可用于回答 why 提出的问题、引导表语从句、用于强调句等，而其余三者均不行：“Why didnt he come?” “Because he was ill.” “他为什么没来?”“因为他病了。”My stomach hurts because I have eaten too many apples. 我肚子痛，因为苹果吃得太多。Thats because you cant appreciate music. 这是因为你不能欣赏音乐。It is because he is honest that I like him. 是因为他诚实我才喜欢他。(2) 关于 since 与 as：a. 两者所表示的原因都是人们已知的，即对已知事实提供理由，而不是表示直接原因。since 比 as 语气稍强，且比 as 略为正式，它们引导的从句通常放在主句之前，有时也放在主句之后：As you werent there, I left a message. 由于你不在那儿，我留了个口信。Since you are wrong, you should apologize. 你既然错了，就应该道歉。b. since 可用于省略句，而其他三者不行：Since so, I have nothing to say. 既然如此，我无话可说。(3) 关于 for：是并列连词(其余三者为从属连词)，它有时可表示因果关系(通常要放在主句之后，且可与 because 换用)；有时不表示因果关系，而是对前面分句内容的解释或推断(也要放在主句之后，但不能与because 换用)。比较：The ground is wet, for (=because) it rained last night.地面是湿的，因为昨晚下过雨。It must have rained last night, for the ground is wet this morning. 昨晚一定下过雨，你看今天早上地面是湿的。 (此句不能用 because 代 for）目标语言（TargetLanguage）四达标测评 基本题型我过关用所给词的适当形式填空1 .What do you think is the most_ (help) invention?2.This machine can be _(operate) easily even a kid can use it.3.Do you think its _(good) to have a TV set than to have a radio? 4You should listen to your teacher as _(care) as possible.完成句子。1.你的手机是国产的吗? _ your mobile phone _ _ China?2.我想给她打电话更好。I think _ would be better _ _her.3.你认为他会选择哪把雨伞？_ _do you think _ _ choose?4.它是由谁发明的？ Who _ _ _by?五课后反思：能力提升走进中考我能赢 单元程序导学案 Period 3 Exercise One一. 单项选择。( )1.
