A B 现在完成时 Present perfect 构成：1. 肯定句 现在完成时的肯定句式是 “have (has)过去分词”。 注意：该句式中的have或has是助动 词，has用于第三人称单数，其它人称 一律用have。 2. 否定句：现在完成时的否定句式是 “havent（hasnt）过去分词”。 3. 疑问句：现在完成时的一般疑问句式 是把助动词have或has提到主语之前。 回答用Yes, have（has）. /No, havent（hasnt）. 连用时间状语：already, yet, ever, never, just, before, several times 等。 动词过去分词的变化形式大部分与动词 过去式形式相同，但是不规则动词的变 化形式没有规律，需要记忆，比如： see-saw-seen; be-was, were-been eat-ate-eaten; break-broke-broken go-went-gone; take-took-taken send-sent-sent; find-found-found make-made-made; have-had-had 现在完成时 Present perfect 现在完成时的完成用法 A、定义：现在完成时的完成用法指的是动作发生在过去 某一时刻并已结束，但该动作对现在产生了影响，与现在 情况具有因果关系。 例如：He has turned off the light. 他已把灯关了。 ( 动作结束于过去，但说明灯现在不亮了。) B、特点：现在完成时完成用法的特点是动作不延续，因 此，该时态只能与表示不定的过去时间状语(如：already ，yet，before，recently等)、频度时间状语(如：never， ever，once等)、包括现在时刻在内的时间状语(如：this morning month year.，today等)连用。 例如： Have you found your pen yet？ 你已找到你的 钢笔了吗？ 现在完成时 Present perfect 现在完成时的未完成用法 A、定义：现在完成时的未完成用法指的是动作开始于过去某 一时刻，一直延续到现在，或可能还要继续下去。 例如：He has lived here since 1978. 自从1978年以来，他 一直住在这儿。 (动作起始于1978年，一直住到现在可能还要继续住下去。) B、特点：此种用法的句中常需一个表示一段时间的状语(由 since或for引导)，或表示与现在时刻相连的时间状语(如：up to now，so far到目前为止)等。 例如：I have heard nothing from him up to now. 到目前为 止我没有他的任何消息。 注意：现在完成时的未完成用法只适用于延续性动词，不可用 于终止性动词，即瞬间完成或延续时间很短的动词。如：come ，go，arrive，leave，join，become，die等。 ( 1).for+表示一段时间的短语 ( 2).since+表示过去时间点的词语 ( 3).since+表示过去时间的时间状语从句 eg.I have been a teacher _ a year. He has been at this school _ 1992. We have learned 1,000 English words _ we came to this school. for since since 现在完成时句中常见的时间状语 A.表示从过去一直持续到现在, 不能是具体 的过去时间。 ever just already yet e.g. Have you _been to Japan? I have _ finished my homework. I have finished my homework _. I havent finished my homework _. B. just, already, yet, before/ ever, never有此 类副词时,常强调动作完成,不强调动作的持续. already “已经” ; yet “仍然, 还” 这两个副词常常用于完成时态, 其中already 常用于肯定句, yet常用于否定句和疑问句中。 如: Jim has already finished his work. Jim已经把他的工作做完了。 Mother hasnt come home yet. 妈妈还没回来。 Havent you read The Call of the Wild yet? 你还没读过野性的呼唤吗？ have been to 与have gone to 的区别 1. have (has) been to意为“曾经去过某 地”，表示现在已经不在那里了。可与 just, ever, never等连用。如： Ive just been to the post office. 我刚才去邮局了。 Have you ever been to Hangzhou? 你曾经去过杭州吗？ Mary has never been to the Great Wall. 玛丽从未去过长城。 have (has) been to 后面可接次数，表示 去过某地几次。 Ive been to Beijing three times. 我去过北京三次。 They have been to that village several times. 他们去过那个村庄好几次了。 have been to 与have gone to 的区别 2. have (has) gone to 意为“到某地去了” ，表示到了某地或正在去某地的途中。 总之，说话时该人不在现场，一般不用 第一、第二人称代词作句子的主语。如 ： - Where is Tom? 汤姆在哪里？ - He has gone to the bookshop. 他到书店去了。 have been to 与have gone to 的区别 have been to 与 have gone to e.g. (1) I have been to Beijing.

He has been a teacher for many years. (2) 一般过去时通常与表示过去的时间状语连用。 如：yesterday, last week, two years ago, just now, in 2002等；而现在完成时则常与just, already, ever, never等副词和these days, this week, since., for.等表示一段时间的状语连用。 动 词 填 空： 1.A：_ you already_ (clean) the room?
