7

南中学案

英语 (必修二)

A

词用 has,其余人称一律用 have。 has,have 的缩略式分别为's 或've。实例: 1) I've just copied all the new words . (表示不要再抄了) 2) She has lost her books . (表示到目前为止还没有找到) (如果用过去时 She lost her books.则强调书是过去丢的这一动作,而不知现在有没有找到) 3) We've just cleaned the classroom . (表明现在教室是干净的) (二)否定式 主语+助动词 have /has+not+过去分词+其它 说明:现在完成时构成否定句时,只需在助动词 have /has 后面加 not 就行。have not, has not 的缩略式分别为 haven't ,hasn't。另外,肯定句中有 some,already 时,改为否定 时要分别改成 any,yet。 实例: 1)I haven't finished my homework yet. 2)She hasn't travelled on a train . 3)We have never spoken to a oreigner. 注:有时 not 可以用 never 代替,表示“从来没有”的意思。又如: 4)I have never seen him before. (三)一般疑问式 助动词 Have /Has +主语+过去分词+其它 ? 说明:把陈述句中的 have 或 has 放到句首,句末打问号,同时把句中的 some ,already 改为 any ,ye t 就构成了一般疑问句。肯定回答用“Yes ,主语+have/has. 否定回答 用“No, 主语+haven't/hasn't. ”有时也可以用“No, not yet. /No , never. /No, not even once.”等。实例: 1)—Have you ever made dumplings ? —Yes ,I have .是的,我做过。 2) —Has she ever been abroad ? —No, never. 不, 从来没有。 3)—Have they found the lost books yet ? —Yes ,they have.是的,他们找到了。 注意:当句中有否定词 not ,hardly(几乎不) ,never 的时候,在改为反意疑问句时,附 加部分用肯定形式。例如:You have never come to our school ,have you ? (四)现在完成时地被动语态:主动语态即主语为动作的执行者;被动语态即主语为动 作的承受者。现在完成时的被动语态同它的主动语态一样,强调过去的动作对现在造成 的影响或结果,但主语为动作的承受者,表示“……已经被……”。如: The new school has been set up. 2) 现在完成时被动语态的肯定式为:have / has + been + done。如: The experiment has been done successfully. 现在完成时被动语态的否定式为:have / has + not + been + done。如: Tom’s novel has not been published. 现在完成时被动语态的一般疑问句需将 have / has 提到主语的前面。如: Has his bike been repaired? 现在完成时被动语态的特殊疑问句为:疑问词 + have / has + been + done。如: Who has been invited? (五)现在完成时被动语态的主要用法 1.表示被动的动作发生在说话之前(即现在的过

A

去),强调对现在造成的影响和结果。例如:The door has been locked.门被锁上了。 (结果是现在没有人能进去) 2.表示一个被动的动作或状态开始于过去,持续到现在,并可能将持续下去,常与 for 或 since 引导的时间状语连用,或用于 How long...?句型中。例如: They have been told about it for many times. (可能还会有人告诉他们) How long has the machine been used? 二、现在完成时的用法 (一)现在完成时的用法 1:表示过去发生或已经完成的某一动 作对现在造成的影响或结果。此时,常与时间副词 already(已经) ,yet(还、已经) , just(刚刚、仅仅) ,ever(曾经) ,never(从不) ,before(以前)等连用。这几个副 词的用法如下: 1.already 意为“已经”,通常用于肯定句中,可放在助动词之后,过去 分词之前,也可以放在句末。实例: 1)I've already read this book. (“读”这一动作发生在过去,对现在造成的影响是“知道书中的内容”。 2)I've washed my clothes already. (洗衣服的动 作已完成,其结果是“衣服冼干净了”。 ) 注意:在表示吃惊或明知故问等感情色彩时,already 也可用于(口语)疑问句中。实例: 3)Have you met him already ? 2.yet 用在疑问句中意为“已经”,用在否定句中意为“还”,常放在句末。实例: 1) —Has he found his watch yet ? No, not yet. 不, 还没有。 2)The woman hasn't found her dog yet . (没找到狗,心里着急,这就是对现在的影响) 3.just 意为“刚刚”,表示行为刚刚过去,常放在助动词与过去分词之间。实例: He has just come back from school . 4.ever 意为“曾经”,用于疑问句或否定句中,放在助动词与过去分词之间。实例: 1)Have you ever been to Hong Kong ? 2)I haven't ever spoken to her. 5.never 意为“从来没有”常与 before 连用(before 要放在句尾,而 never 多放在助动词与 过去分词之间.实例:I have never travelled by plane before.我以前从来没有乘飞机旅行过。 6.before 意为“以前”,指过去不确定的某个时间,总是放在句末,不受句型的限制。实 例:1)Have you been to Hainan before ? 2)I haven't eaten Guangdong food before. (二)现在完成时用法二——持续性用法(肯定句,疑问句中谓语动词必须是延续性动 词) :表示过去已经开始,持续到现在的动作或状态。此时常与“for +一段时间 或“since +过去的点时间或从句(从句用一般过去时)以及 so far(到目前为止)等时间状语连用。 for + 段时间, since +点时间 实例: 1) 自从 1990 年以来我就住在这里。 I've lived here since 1990. = I've lived here since 13 years ago. = I've lived here for 13 years. = It is 13 years since I began to live here. 2)我三年没有看见他了。I haven't seen him for three years .= I haven't seen him since three years ago = I haven't seen him since 2000. = It is 3 years since I saw him last time.

3)Mr Wang has worked in the factory since he came to the city . 自从到这个城市以来,王先生一直在这家工厂工作。 4)She's been at this school since five years ago. 自从五年前以来她就在这个学校。 注意:①在这类句子的肯定句和疑问句中谓语动词必须用延续性动词。短暂性动词由于 动作不能持续,故不能与 for(达到;累计)或 since(自从。 。 。到现在)引出的时间状语连 用。 ②对 for 和 since 引导的时间状语提问要用 How long 1) 他入团两年了。 误:He has joined the League for two years. 正:He has been a League member for two years. 2)我买这辆自行车三年了。 误:I have bought this bike for three years. 正:I have had this bike for three years. 2) ▲部分短暂性动词与之对应的延续性动词: 短暂性动词 延续性动词 die → be dead borrow → keep buy/catch → have get up → be up come → be in finish → be over leaver → be away open → be open close → be closed begin → be on become interested in → be interested in 注意:1.一般过去时和现在完成时所表示的动作的区别: ①一般过去时与具体的表示过 去时间状语如:yesterday 连用;强调动作在过去发生,与现在无关。②现在完成时与自 己的特征词连用,强调过去发生的动作对现在的影响或过去开始发生一直持续到现在的 动作。例:He saw the film last night. (过去时,表示他昨晚看过那部电影了,现在不知还 要不要再看一次) He has (ever) seen the film before.(现在完成时,表他已看过那部电影,现在不想再看了) 2.用于现在完成时的句型:1)It is the first / second time…. that…结构中的从句部分,用现 在完成时。 It is the first time that I have visited the city. It was the third time that the boy had been late. 2)This is the… that…结构,that 从句要用现在完成时. This is the best film that I've (ever) seen. This is the first time (that) I've heard him sing. Exercise:一. 句型转换。 1、He has never surfed, ?(改成反意疑问句) 2、They have been here since 2000. (对划线部分提问)
