人教版八年级英语下册第二单元.docx

Unit2 Ill help clean up the city parks. 【教材依据】 本单元是人教版初中英语新教材八年级下册第二单元，本单元的核心话题为“volunteering”，通过本单元的学习，使学生能向别人提供帮助，争做一名志愿者。 【设计思路】本单元的中心话题是提供帮助，围绕着主动提供帮助以及志愿活动展开生动、活泼的对话和阅读，以观察图片、听力理解、阅读理解等训练方式和独立学习、合作交流、完成任务等形式完成目标语言的输入，学习 “I will ”，“I would like”等句型和一些重要动词短语为主要学习内容，并且设置任务型综合性语言实践活动，让学生在交际活动中，学会如何正确地用英语表达自己的意见和建议，重在培养学生的习得语言运用能力、实践能力、合作能力及创新意识。由于本单元的这些志愿活动与我们的生活密切相关，通过本课的学习，还要求学生能够谈论自己帮助别人的方式，学会关心社会，关爱他人。引导学生体会志愿活动，投身于社会公益事业。根据新目标对学生交际能力的培养，我将本课设计为一堂听说课。但对于八年级的学生可能已经不像七年级学生那样热衷于普通的课堂活动,所以设计怎样的课堂活动，采取怎样的评价方式来提高课堂气氛，从而使学生自然地融入整个教学环节显得尤为重要。【设计重点和难点】 根据教材的内容和学生的实际情况，我们可以围绕“我爱矿区，我要成为矿区志愿者的一员，尽自己的能力去帮助身边需要帮助的人”这一在中心思想来开展一系列教学活动。在培养学生听、说、读、写能力的基础上，培养学生爱家乡，爱矿区，形成健康的人生观，为他们的终身学习和发展打下良好的基础。 本课时主要运用动词词组围绕“volunteer”展开话题,怎样在规定的时间内通过什么样的活动来激发学生的学习热情,让学生自然地学会运用如此多的动词词组,并成为课堂教学的主角是这一课时的难点。【教学目标】 1 .Knowledge objects(1) Key vocabularyclean up, hunger, cheer up, give out, volunteer, homeless, come up with, put off, hand out, call up, sign, lonely, used to(2) Target languageId like to work outside.
