2.语态对比：对比两组句子——Scientistswillbuildspacestations./Humanswilldiscovernewplanets.与Spacestationswillbebuiltbyscientists./Newplanetswillbediscoveredbyhumans.提问：Whatisthedifferencebetweenthesetwogroups?引出主动语态（强调“谁做”）与被动语态（强调“什么被做”）。教师播放视频，提出两个问题，引导学生对比两组句子的差异；学生观看视频思考未来太空建设，观察句子对比，初步感知主动与被动语态的区别。以太空探索视频创设情境，通过两组句子的直观对比，帮助学生建立“主动语态强调谁做、被动语态强调什么被做”的概念框架，自然引入本课语法点。Step2Task2语法感知+概念建立7min1.观察感知（4a）：阅读五个句子——Newtechnologywillsoonbedeveloped./ExplorationoftheplanetMarswillbecontinued./InternationalresearchstationswillbebuiltonthemoonandMars./Willlifebefoundonanotherplanet?/Willyoubevisitedbyotherastronauts?划出被动语态谓语，注意一般将来时的用法，总结：一般将来时被动语态willbedone。

2.用法探究：Whydoweusepassivevoicewhentalkingaboutfuturespaceplans?总结：Wefocusonwhattodoinsteadofwhotofinish.明确willdo（一般将来时）与willbedone（一般将来时被动语态）的区别。教师呈现4a句子，引导学生划出被动结构并总结规律，组织用法讨论；学生观察例句、圈划谓语动词，归纳willbedone结构并理解使用被动语态的原因。以本单元太空计划句子为语料，让学生在观察中自主发现一般将来时被动语态的结构与语用价值，实现“感知—归纳”的语法学习路径。Step3Task3结构梳理+即学即练9min1.句式结构：讲解一般将来时被动语态结构——肯定句：Subject+will+be+done；否定句：Subject+willnot(won't)+be+done；一般疑问句：Will+subject+be+done?及简短回答Yes,subjectwill./No,subjectwillnot/won't.拓展begoingto结构（am/is/aregoingtobedone）的肯定、否定与疑问形式。

2.即学即练：完成动词适当形式填空（willbebuilt,willbespread,willbecorrected,willbemade），渗透解题技巧：先判语态、再定时态、最后变形式。教师借助结构图表讲解句式构成，组织即时填空练习并讲解技巧；学生记录结构公式，运用“先判语态、再定时态、最后变形式”的技巧完成填空。系统梳理一般将来时被动语态的各类句式与begoingto变体，通过即学即练当堂检验掌握情况，渗透中考动词形式题的解题技巧。Step4Task4主动变被动+4c语篇应用11min1.转换方法（Task4）：总结主动语态变被动语态三步法——Step1换位：主动句宾语移至句首，作被动句主语；Step2变形：谓语改为willbe+动词过去分词；Step3处理发出者：主动主语放by后，可省略。以Thisprojectwillrequirestudentstodoresearchonspaceexploration.→Studentswillberequiredtodoresearchonspaceexplorationbythisproject.为例逐步演示。

2.转换练习（4b）：完成五个主动句变被动句练习并核对答案（willberequired...bythisproject/willbepositionedinspacebyscientists/tothespacemuseumwillbecancelledbecauseofthebadweather/aboutfuturespacetravelwillbepublishedbythemagazinenextmonth/anewrocketbelaunchedbythespacecentrenextmonth?）。

3.语篇应用（4c）：用括号内词语的正确形式完成系外行星短文并核对答案（isfilled,discovered,move,havebeenknown,willbefound,isthought），了解Whatareexoplanets?（Theyareplanetsthatmovearoundstars—justlikeinourownsolarsystem.），并运用句型框架（Ithinkitwouldbeexcitingbecause.../Itwouldchangethewaywethinkabout.../I'mnotsureif...because.../Mymainconcernisthat.../Iwonderif...等）讨论Whatareyourviewsonfindinglifeonanotherplanet?教师演示三步转换法，组织4b转换练习与4c语篇填空，引导学生讨论对系外行星与寻找外星生命的看法；学生掌握转换步骤，独立完成练习，并在语篇中辨析不同时态的被动语态。通过“方法演示—句型转换—语篇填空”逐层递进，实现语法从形式操练到真实语篇的运用；讨论环节将语法学习与太空探索话题结合，培养思辨与表达。Step5语言点精讲+当堂检测8min1.语言点精讲：讲解require（v.需要；要求——requiredoingsth需要被……（主动表被动含义）；requiresb.todosth要求某人做某事）与discover（v.发现（原本存在但不为人知的事物））。

2.当堂检测：完成句型转换练习（willbesent;Wherewill...bebuilt;Will...beinvited;isgoingtobefinished;willberepaired）与短文填空（wasconsidered,hasbeendeveloped,willbetested,willbesold,willbeaccepted），并核对答案。教师结合例句精讲require与discover的用法，组织句型转换与短文填空并当堂反馈；学生记录语言点，独立完成检测练习，巩固一般将来时被动语态。讲练结合，突破requiredoing（主动表被动）与discover词义的难点，通过两类检测题检验并夯实本课语法学习效果。分层课后作业层次作业内容基础必做1.抄写本课一般将来时被动语态结构公式（肯定句/否定句/一般疑问句及begoingto变体）与动词过去分词（require-required,discover-discovered,position-positioned,cancel-cancelled,publish-published
