文本分析：
[What]本节课围绕主题语境设计了四个活动：第部分是识别并了解主语从句的特征和功能。第二部分是从句匹配练习，根据对句子的理解，选择符合句意的另部分，再通过分析句子结构，判断所选的主语从句的连接词的功能，并对这些句子进行翻译。第三部分是一篇关于退休的爷爷奶奶选择到农村居住，过上绿色生活的短文，进一步帮助学生理解主语从句在语篇中的作用。第四部分要求学生以小组讨论的形式，根据已给观点及句型，描述像袁隆平一样的成功人士所具有的优秀品质，让学生尽可能多地使用主语从句，并在全班展示。
[Why]在单元主题语境中学习主语从句，让英语句式表达更丰富多彩。

Step I 学习理解
活动一：识别主语从句（Part1，P53）
Lk at the cmplex sentences belw and state the functins f the nun clauses italicised. Then find similar cmplex sentences frm the text.

Hwever，whether it was pssible t develp a hybrid f self-pllinating plants such as rice was a matter f great debate.
What impresses peple mst abut Yuan Lngping is his nging ability t fulfil his dreams.
【设计意图】通过介绍袁隆平这位农业先驱的事迹和在课文中寻找更多含有主语从句的句子，使学生在具体语境中分析句子结构，识别主语从句。
Step Ⅱ 应用实践
活动二：补全句子（Part2，P53）
Match the sentence parts，and then translate the cmpleted sentences int Chinese. Pay attentin t hw the subjects are intrduced differently.
Suggested answers：
①D 这些小麦农户什么时候会加入预试验仍然不得而知。
解析：当主语从句中句子成分完整，询问“时间”时，主语从句用when引导。
②C 如何能够找到一个合适的解决办法，在保证环境安全的同时，生产足够的粮食，是一个需要我们研究的重要课题。
解析：主语从句中句子成分完整，询问“方式”时，主语从句用hw引导。
③A 令很多人担心的是，这些化学制品甚至可能导致癌症。
解析：主语从句中缺少主语，表示“什么”用what引导。
④E 令我们所有人惊讶的是，通过这种新技术，可以无土栽培这些蔬菜。
解析：it为形式主语，that引导的从句是句子真正的主语。
⑤B 有些人更喜欢住在乡下而非城市的原因是前者生活节奏更慢、生活方式更健康。
解析：主语从句结构完整且描述的是事实，所以用that引导。
【设计意图】通过对句子的理解，让学生在补全句子的基础上，分析句子成分，区别主语从句连接词what、that、hw、when的用法，进一步要求学生翻译整个句子。从这些练习中感受、总结出主语从句的特征，并正确使用。
活动三：强化训练（Part3，P53）
Read the passage and underline all the subject clauses. Then in pairs，discuss whether the sentences with subject clauses can be paraphrased.
Suggested answers：
1. ...，that they lk beautiful n the utside is bvius.
→...，it is bvius that they lk beautiful n the utside.
2. Hwever，what she is unhappy abut is the lwer nutritinal value and reduced flavur.（Can’t be paraphrased）
3. ...，hw they are ging t spend their retirement is an imprtant decisin fr them.
→...，it is an imprtant decisin fr them hw they are ging t spend their retirement.
4. Whether they can live a healthy life is the first thing they are cnsidering.
→It is the first thing they are cnsidering whether they can live a healthy life.
小结：
主语从句常用it作形式主语，常见句型有：
1.It+be+形容词十主语从句.（bvius，clear，certain，uncertain，true，natural，strange，likely..）
2.It+be+名词十主语从句.（a pity，a fact，a mystery，a shame，an hnur，a questin，cmmn knwledge…）
3.It+be+过去分词+主语从句.（annunced，believed，expected，hped，decided，reprted，said，shwn，well knwn，prved…）（此结构中的主语从句不可提前）
4.It十不及物动词十主语从句.（seem，appear，happened…）（此结构中的主语从句不可提前）
【设计意图】通过分析句子结构，判断出语篇中含有主语从句的句子，并让学生通过小组讨论的形式判断该主语从句是否可以转化为同义句。通过进一步练习，使学生明确主语从句的特征，了解为避免头重脚轻，常会以形式主语it引导从句，并灵活使用。
Step Ⅲ 迁移创新
活动四：情境应用（Part4，P53）
What qualities d yu think make a persn like Yuan Lngping s successful？Wrk in grups.Have a discussin and prepare a presentatin.The fllwing pints and expressins may help yu.
Suggested answer：
Hell everyne! Tday I'm glad t share yu a great pineer in agriculture—Yuan Lngping. It is knwn t us all that Yuan Lnging always cnsiders himself a farmer. Actually, he is famus as the "father f hybrid rice" bth in China and Abrad.
What impresses me mst is that he refused his parents' suggestin t study science r medicine in a cllege and went t receive an educatin at Suthwest Agricultural Cllege in Chngqing. What makes him a great scientist is his determinatin t tackle the crisis f the pr harvests and starvatin f farmers. It is imprtant that he had a dream t develp high utput rice—hybrid rice. Whether his dream wuld be accmplished depended n his intense effrt t vercme all the difficulties during the research. It excited the whle wrld that he succeeded in finding the slutin t bsting yield in the field. That his lve and care fr his peple makes him belved. That he is devted t circulating his knwledge in Asia and many less develped cuntries t increase their harvests has been helping rid wrld hunger. That he never gives up and cares little abut mney and being famus are his mst imprtant qualities.
【设计意图】在学习和练习了主语从句的用法之后，要求学生以小组讨论的形式，根据已给观点及句型，描述像袁隆平一样的成功人士所具有的优秀品质，尝试尽可能多地使用主语从句，并在全班展示。把语法置入特定的语境中，学生将自己在阅读部分中对袁隆平的了解与本单元的语法主语从句紧密地结合起来，尝试去表达自己的想法，这加深了对主语从句用法的理解，改变了单纯语法练习，提高了学习语法的兴趣。
