III Practice ----Make a sentence(PP6、PPt7设计意图:检测学生对现在完成时的理解和掌握程度,遵循由浅入深如:先肯定句再否定句子,再一般疑问句;先用“have”再用“has” 在此强调主格变化情况)
IV To learn No.2 Studyhing aims (PPt8常与现在完成时连用的副词:already、just、yet此环节举例子让学慢慢体会三个副词在句子中意思及它所表达的意境)
I've just made a model spaceship.
Astronauts have already been to the moon.
We have not found life on any other planets yet.
Has it arrived yet?
V Grammar summary(设计意图PPt9:语法小结使学生更清晰记牢already、just、yet三个副词的用法及区别)
语法小结: “刚刚做完某事” “已经做完某事”时,同样用现在完成时,just 用来表示“刚刚”,already 用来表示“已经”,一般置于have/has之后,两者都用于肯定句,在否定句和疑问句中则要用yet,表示“还、尚(未)”通常放在句末。
VI Practice(设计意图PPt10:从此环节起为本节微课重点语法项目的输出环节做一些笔头练习进一步熟练掌握“already、just、yet”三个副词的用法及区别 )
VI Practice ---Make a conversation(设计意图PPt11:培养学生综合运用语言能力形成自己的语言也口头的表达能力,能很好贴近生活使学生学到的知识更多运用到实际生活当中去达到学中用、用中学、学以致用、知行合一)
A: Have you… ?
B: Yes, …/ No, …
(using already, just, yet)
VI Practice-----Complete the news with“ already, just and yet” (设计意图PPt12. 培养学生运用所学知识对综合整篇阅读理解能力,进一步对所学知识强化及提升的过程,较好把握文章主旨及所学知识元点在文中所起到作用,更好体会“我中有你,你中有我”的文段意境及副词“already、just、yet”在文中不可缺少文段语境)
