英语语法现在完成时
英语语法现在完成时一、现在完成时的基本结构肯定句:主语+have/has+动词的过去分词+其他否定句:主语+have/has+not+动词的过去分词+其他一般疑问句:Have/Has+主语+动词的过去分词+其他特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他)二、现在完成时的用法1. 现在完成时用来表示过去已经完成的动作对现在造成影响或后果。
也就是说,动作或状态发生在过去但它的影响现在还存在,强调的是现在。
I have already posted the photo.我已经邮寄出了照片。
与此种用法连用的时间状语时一些模糊的过去时间状语,如already(肯定句句中), yet(否定句/疑问句句尾), just, before, recently,still, lately,never等。
2. 现在完成时也可用来表示动作或状态发生在过去某一时刻,持续到现在并且有可能会继续持续下去。
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。
)此种用法常与for(+时间段),since(+时间点或过去时的句子)连用。
谓语动词必须是延续性动词。
有些瞬间动词可变为延续动词:go out----be outfinish----be overopen----be opendie----be deadbuy---havefall ill---be illcome back----be backcatch a cold----have a cold三、现在完成时常见考法对于现在完成时的考查,多以单选、句型转换或词语运用的形式考查学生在具体语境中灵活运用时态的能力。
在考试中,会让大家判断是否该用现在完成时,或者是考查“瞬间动词”不能与表示一段时间的状语连用”这一知识点。

现在完成时说课课件
现在完成时说课课件现在完成时说课课件现在完成时说课课件(一)内容分析现在完成时是课程标准要求学生重点掌握的语法项目,也是初中英语语法的重点和难点之一。
语法现象较为复杂,难度较大,是中考重点考查的内容之一。
其考点主要体现在:1.基本用法。
2.havegoneto/havebeento/havebeenin的区别。
3.延续性动词和费延续性动词在现在完成时中的应用。
4.现在完成时与一般过去时的区别。
根据以上考点的分析和发展学生的综合运用语言的能力为宗旨制定一下教学目标(二)教学目标:1.知识与能力:通过复习使学生巩固现在完成时和一般过去时的有关知识,能够运用所学知识解决时态的题目。
2.过程与方法:通过复习提高学生综合运用所学知识解决问题的能力。
3.情感态度:通过复习使学生树立较强的自信心,形成克服困难的意志。
(三)教学重难点由于英语和汉语两种语言对“完成”和“过去”概念定义的差异,学生往往对两种时态的含义和用法产生混淆,同时两种时态既有联系又有区别,因此,正确理解现在完成时和一般过去时的用法及区别,正确使用现在完成时和一般过去时解决有关时态的题目既是本节课的重点,又是本节课的`难点。
二.教法学法分析说教法:结合教材和复习课的特点,采用讲授和练习相结合的教学方法。
精讲巧练,循序渐进地深化教学内容。
展开以教师为主导,以学生为主体的师生双边活动。
说学法:结合教学内容,在课堂上指导学生使用了比较归纳、分析概括的方法,这样不仅有利于学生更好地从整体上理解和把握知识的结构和体系,更有利于发展学生求同辩异的思维能力,培养学生的自学能力。
三.教学过程分析第一步:知识复习总结,首先分别复习现在完成时和一般过去时的有关知识,对重点进行分析并结合习题进行巩固,再对两种时态进行比较归纳,使学生从整体上理解和把握这两种时态的结构和体系。
第二步:知识点练习。
结合历届中考试题中部分考查现在完成时和一般过去时的试题让学生在规定时间内完成。

英语语法大全:现在完成进行时
英语语法大全:现在完成进行时现在完成实行时现在完成实行时和现在完成时一样,表示从过去某时开始到现在这一段时间里一直延续着的动作。
现在完成时侧重于动作的结束或完成;而现在完成时则侧重于动作的未结束和继续实行。
我打了门。
(完成了这个单一动作。
)现在完成实行时 I have been reading aloud the poem sincethen.从那时起我一直在朗读这首诗。
(动作从过去一直持续到现在还在继续。
)1 现在完成实行时的形式肯定句主语+have (has) been +现在分词(doing)….[比较]现在完成时的被动语态主语+have (has) been +过去分词(done)….疑问句 Have(Has)+主语+been +现在分词(doing)…?Have you been writing all the day?你一整天都在写吗?How long has it been raining?雨下了多久了?It has been raining for three days.雨下了三天了。
He hasn’t been sleeping for 5 hours.他没有一直睡了五个小时。
——而是四个、三个或六七个小时。
(这句话中否定词在形式上似乎是否定谓语hasn’t been sleeping,但实际上却否定了状语for 5 hours.)注意现在完成时有否定结构,而现在完成实行时基本上没有否定结构。
2 现在完成实行时的用法1.在强调指出动作还未结束,还要继续下去时不能用现在完成时,而要用现在完成实行时,以避免使人误认为动作已经全部完成。
I’ve been writing the composition for two hours, but I haven’tfinished it yet.这篇作文我写了两个小时了,但还没写完。
(强调动作没有结束,还要继续写下去。
)I’ve written the composition. I’m not satisfied with it. Youcan read it and tell me what you think of it.我已经写完了这篇作文了。
