Unit 6 How long have you been collecting shells（第1课时）Section A 1a-1c导学案一、学习目标: 现在完成进行时能力目标: 了解现在完成进行时重点词语: collect , shell, skate,重点句子：How long have you been skating? Ive been skating for five hours.-How long did you skate? -I skated for two hours.-What sport do you play? -Tennis.-When did you start? -When I was eleven.难 点：区别不同点：“How long have you been skating?” And “ How long did you skate?”二、预习导学1.大声朗读目标1中的生词并能熟记这些生词。2.合上书后又快又好地完成如下任务：collection(v.)_ shell(复数)_滑冰鞋_ 自从_ 一双_滑冰马拉松_ how long_ a pair of skates_3.小组谈论1a 中的问题，并作答。 4.教师引导总结学习现在完成进行时。三、自学检测1.用所给动词的正确形式填空。四、合作探究 现在完成进行时1.现在完成进行时表示从过去开始一直持续到现在的动作,而且还要继续下去。2.现在完成进行时的构成： 肯定句：主语 + have / has been + doing . 否定句：主语+have/has + not + been + doing 一般疑问句：Have/Has + 主语 + been + doing? 3.现在完成进行时的用法： 现在完成进行时的句子中多用延续性动词,如live, learn, study, work等，常与for two hours, since 1998,all this morning, these few days等表示一段时间的状语连用。强调“谈论一直做某事”如: I have been cleaning the room all this morning. 我今天一上午都在打扫房间。Ive been studying English since I was 4 years old. 自从4岁起我就一直学英语。4.现在完成进行时与现在完成时的区别：(1)现在完成时强调动作的完成，而现在完成进行时侧重的是动作的持续进行。如：I have read a book about birds. （已经读完） I have been reading a book about birds.（一直都在读,现在还在读,有可能会继续读下去）(2)两种时态都有延续性， 但现在完成时往往只说明一个事实，一种影响或结果，无感情色彩；现在完成进行时表示一个动作的延续、重复，有时有一定的感情色彩。 如： She has been singing all the day. 她都唱了一整天了。（抱怨、厌烦）五、展示 1.个人或小组读。2听录音完成1b。3.对话练习1C六、学以致用必做题单项选择选做题6.
