《Section A Grammar focus 4a-4c》教学设计八年级下册人教版-八年级英语教案

学校：教师：课题:Unit10I’vehadthisbikeforthreeyears.(GrammarFocus4a–4c)预计授课日期：教材分析：本单元的重点语法项目是带有since和for的现在完成时的句子。GrammarFocus表格总结了本单元的典型例句，包括由howlong引导的现在完成时的特殊疑问句，分别用for和since回答的例句，还有现在完成时的一般疑问句。教材4a-4c的活动编排不仅体现了从易到难的层次性，活动的设计也是从控制性到开放性，从机械的语法练习到实际运用。这一活动有助于学生之间的信息沟，使他们能在相对真实的交际环境中使用目标语言，也增强了学生之间的互动和相互了解。学生分析（学情分析）：从整体来说，学生的学习积极性还是比较强的，大多数学生学习态度较端正。部分学生学习的兴趣不够浓厚，学习的主动性不强，两极分化现象比较严重，尖子生不够突出。大部分学生还存在着依赖性，不愿意自己探究知识，没有好的学习习惯，还要教师在今后的学习中进行渗透。教学目标：1．知识目标：掌握现在完成时的用法 2．能力目标：正确区分现在完成时与一般过去时；正确运用for

和since的用法。 3．情感态度价值观：正确处理并充分利用自己的废旧物品。教学重难点：1.教学重点：会运用现在完成时。

2.教学难点：学习现在完成时表示过去某一段时间已经开始一直持续到现在的动作或者状态。教学方法与手段：任务教学法情景教学法教学过程：教学环节教师指导与评价学生学习活动设计意图leadin问题引领2.Expressioncomplete4aStudybyThemselvescomplete4plete4c6.ExerciseLastclass,wehavelearnedsomethingaboutPresentPerfectTense.Howmanythingsdoyouremember?Nowopenyourbookandturntopage76.ReadtheGrammarFocusandthesentencesontheblackboardandworkingroups.(板书)A:Howlonghaveyouhadthattoybear?B:Ihavehadthetoybearformorethansixyears.(2)A:Howlonghasheworkedasapoliceman?B:Hehasworkedasapolicemanfortenyears.(3)A:Howlonghavetheyworkedthere?B:TheyhaveworkedheresinceJune.(4)A:HowlonghasshestudiedEnglish?B:ShehasstudiedEnglishsinceshewasfive.Questions:1:现在完成时的特殊疑问句的结构是什么？用什么疑问句来询问拥有某物品的时间？for后面接什么？Since后面接什么？7.for与since的转换Allofyouhavedoneagoodwork.Nowlookatthefollowingsentencesandtellmeitistrueorfalse.HowlonghasMaryleft?HowlonghasMarybeenaway?Howlonghasheborrowedthebook?Howlonghashekeptthebook?MariahascomebacksinceMonday.MariahasbeenbacksinceMonday.教师总结buy–havehadleave—havebeenawayBorrow—havekeptDie—havebeendeadBegin-havebeenonOpen-havebeenOpenRewrite
