教学过程内容画面时间一、片头(20秒以内)内容:您好,这个微课重点讲解辨析for和since的用法第 1 至张PPT2秒二、正文讲解(4分20秒左右)第一节内容:辨析for和since的用法第 2 至11 张PPT315 秒第二节内容:典型例子第 12 至 14张PPT116 秒第三节内容:总结内容第 15 至张PPT40 秒三、结尾(20秒以内)内容:感谢大家能认真的听完这个微课,希望大家回去后多做练习加以巩固。

第 16至张PPT 1 秒教学反思(自我评价)本微课通过用PPT的方式讲解了for和since的用法,因为是辨析两个单词的用法,因此我用了归纳法进行讲解,让学生在例子中发现规律,然后进行总结。

但是,在讲解的过程中,我所举的例子可能太少了,给学生思考和练习的时间也很少,中等以下的学生可能对知识点还不是很理解。

通过这节微课,我觉得在以后教学中,我要认真分析学生的认知能力,顾及大部分学生,然后寻找更好的教学方法,或者在讲解释可以使用多种方法,归纳法或者演绎法等,让学生理解所教授的内容。

人教版英语八年级下册现在完成时(易懂版本)

现在完成时一、两个含义:①表示动作发生在过去,但对现在的情况造成了影响。

(借古讽今)He opened the door.The door is open.I saw the movie.I have seen the movie.I got married.I have got married.②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作,用于延续性动词,且句中常带有表示一段时间的时间状语,如:since + 时间点/从句,for two months, so far等。

(从古至今)I have learned English for 10 years/since 10 years ago.I have lived in Chengdu for 12 years/since 12 years ago.I have been a teacher for 2 years/ since 2 years ago.二、构成have/has+动词的过去分词(done)三、标志词for, since, already, yet, before, recently, over the …., in the past few…..四、already与yet的区别already用于肯定句(已经)yet用于否定句(还)和疑问句(已经)ever & neverever作副词,意为“曾经”,常用于现在完成时的一般疑问句和肯定句中,置于主语之后,过去分词之前。

never作副词,意为“从不;从未”,用于现在完成时中,表示否定,位于助动词have/has之后,过去分词之前。

五.have been to & have gone to & have been inhave been to 去了某地,已回have gone to 去了某地,未回have been in 在哪里待了多久后面是地点副词there、here、home 时,省略to六、延续性和非延续性1. 含义:延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。

for和since现在完成时的用法

for和since现在完成时的用法

“for”和“since”在现在完成时中的用法如下:
“for”用于表示一个时间段,即动作持续的时间长度。

它通常与表示时间的名词(如年、月、日、小时等)连用,表示某个动作或状态持续了多长时间。

例如:“I have lived here for five years.”(我已经在这里住了五年了。


“since”用于表示一个时间点,即动作开始的时间。

它通常与表示过去某个时间点的词语(如从句、过去分词等)连用,表示某个动作或状态从何时开始一直持续到现在。

例如:“I have not seen him since last year.”(自从去年以来我就没有见过他。


需要注意的是,“for”和“since”在现在完成时中的用法是有所区别的,需要根据具体语境进行区分。

同时,在使用现在完成时时,还需要注意动词的正确形式,以及与时间状语的搭配等问题。

英语人教版八年级下册Present perfect tense

英语人教版八年级下册Present perfect tense
(只说明他过去学过五年英语,但现在不学了。)
He ___________(work) has worked in our school for one year.
came He _______(come) to our school last year.
have cooked They ____________(cook) the supper already. cooked (cook) the supper half an hour ago. They _______
※延续性动词与非延续性动词在现在完 成时态中的使用
(1)在现在完成时态中,延续性动词又称持续性动 词,可与表示一段时间的状语连用。 例如:study, eat, have ,teach, keep, stay等 (2)非延续性动词也称短暂性动词或瞬间性动词, 指表示短时间的动作,这些动词一发生就结束了, 常见的有come, go, arrive, reach, leave, begin, start, buy, join, die, borrow, get up, open, stop, marry等因此不能跟表示一段的时间状语连 用,因此要把它转为相应的延续性动词或短语。
现在完成时态的结构: have/has+动词的过去分词
现在完成时和一般过去时的区别:
现在完成时,强调这一动作产生的结果对现 在的影响,与现在有关。 一般过去时,仅仅表示在过去某一时刻曾发 生过这一动作,与现在无关。 He has studied English for five years.
(学习英语已经五年了,现在仍然在学)
He studied English for five years.

英语人教版八年级下册九年级英语现在完成时态语法复习讲解及练习(含答案)

英语人教版八年级下册九年级英语现在完成时态语法复习讲解及练习(含答案)

现在完成时态的讲解及专项练习现在完成时是初二要学到的语法内容,也是中考的重点和难点。

一. 现在完成时基本结构①肯定句:主语+have/has+动词的过去分词②否定句:主语+have/has+not+动词的过去分词③一般疑问句:Have/Has+主语+动词的过去分词④特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词)二. 现在完成时用法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 1996自从1996年以来,他一直住在这儿。

(动作起始于1996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. 现在完成时常见考点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。
