现在完成时的用法讲解1
现在完成时的讲解 对所学时态的回顾，引入现在完成时 通过数轴来概括讲解所学的四个时态：一般现在时、现在进行时、一般过去时、一般将来时。 （导入）有时候，这4种时态还不能满足我们表达的需要。比如：表示“某人过去曾经做过某事”或者“某人做某事多久”，以上五种时态就派不上用场了。这时，我们可以用一种新的时态——现在完成时表示。同样也用数轴来表示一下。 taught will teech -------- ---------- -------- --------- ---------- ? —过去时now 垠时 is teaching fit在发生） -------- ---------- -------- --------- ---------- ? DOW 枉进行时 past two years （has taught） ------ --------------------------------------------- Two years ago 现在完成时now 一现在完成时的构成：主语+ have/has +过去分词 （过去分词：规则动词的过去分词构成与动词过去式相同；不规则动词需要特殊记忆。 eg」_ have taught English in this school since 1999. 二、否定式：主语+ haven' t/hasn' t +过去分词。 疑问式：Have /Has +主语+过去分词？ 简略答语：Yes,主语+ have/has.肯定） No,主语+ haven' t/hasn' t.（否定） —Have you finished your work? —Yes,l have. 三现在完成时的含义之一表示过去发生或已经完成的动作对现在造成的影响或结果， 常与already/yet，just，never/ever, before, so far等连用。这些标志词可以表达这种含义 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）rve already read this book.我已经读过这本书了。 （“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）rve washed my clothes already 我已经洗了衣服。 （洗衣服的动作已完成，其结果是“衣服冼干净了”。）
现在完成时的用法解析
Lead in 一般过去时导入：一般过去时的概念 一般过去时表示过去某个时间发生的动作或存在的状态。 I lost my pen.(过去时) I have lost my pen.（现在完成时） 过去时一般表示过去所发生的动作或存在的状态。“我把笔丢了”，说话人只是想告诉对方在过去的某一个时间里他的笔丢了，仅此而已。（仅仅是在陈诉过去的一个事实，与现在没有关系） New lesson 一．现在完成时的构成： 助动词have/has(not) +动词过去分词 She has turned on the lights. 肯定式：have/ has+过去分词 否定式：haven’t/hasn’t+过去分词 疑问式：把have/has 提到主语前面 肯定回答：Yes,…have/has 否定回答：No,…..haven’t/hasn’t 二．用法 1.表示过去发生的动作对现在造成的影响或结果. 例如:She has gone. 她走了. She went in the past.(She is not here
now.) I have just cleaned my hands. 我刚洗过手。（“洗手”是发生在过去的动作，对现在造成的结果是“手干净了”） I have closed the door. (The door is close now.) She has turned on the lights. (The lights are on now.) He has written his name on the blackboard. (The name is on the blackboard now.) Mother has cooked the dinner. (We can have dinner now.) You have seen the film. （You know what the film is about.) We have cleaned the classroom. (The classroom is clean now.) 2. 表示动作发生在过去，并且一直延续到现在，甚至还可能继续延续下去。这时常和since所引导的短语或从句或for引导的短语连用(for有时可以省去)。以及so far, by now, these days, in the last/past … years/days…等连用。 I have lived here for over ten years. （表示他现在还在这里居住，并且还有可能继续住下去）比较：I lived here ten years ago.(仅仅说明了他十年前在这里记住过的事实,不代表现在他还住在这里) He has studied here since 2006. 都用How long 提问，例： We have learned English for three years. We have learned English since three years ago.
unless 与 if not
Unless 与 if not 1. unless 与if … not 都可以用来引导条件状语从句， unless 的语气较重，从句中的动词用一般现在时代替一般将来时。例如： We will visit the Great Wall tomorrow unless it rains. 除非明天下雨，否则我们就去参观长城。 I won't believe what you said unless I've seen it with my own eyes. 我要亲眼所见才能相信你所说的。 Don't enter the lab unless you are permitted to. 只有经过允许才能进入实验室。 2. 有的同学在遇到使用 unless 的句子时，弄不清该用肯定还是否定而出错。这时最好的办法是将 unless 替换成if … not 的结构，从而就一目了然了。例如： I won't go to the party unless I am invited. （ =I won't go to the party if I am not invited. ） 如果没有人邀请我，我是不会去参加聚会的。 3. 由于 unless 与if … not 的语气不同，有时两者替换后，其意思就不一样了。例如： Unless he were my friend, I shouldn't expect his help. 除非他是我的朋友，我才会期待他的帮助。（本句的潜在意思为：他并不是我的朋友。） If he were not my friend, I shouldn't expect his help. 如果他不是我的朋友，我就不会期待他的帮助了。（本句的潜在意思为：正因为他是我的朋友，我才会期待他的帮助。） 4. 在平时使用过程中，要注意 unless 与 until 的区别。
