教学过程：
一、Pre-
1. Greeting
2. Leading-in
学生活动：
1、学生观察并分析活动 1中的句子，通过理解句子的结构和意义，画出主语，识别主语从句，并观察that引导的主语从句在句中的位置以及形式主语it的用法。
What Yuan Lngping really cared abut was nt mney r celebrity.
That Yuan Lngping had realised his dream f seawater rice surprised the whle wrld.
It surprised the whle wrld that Yuan Lngping had realised his dream f develping seawater rice.
•第一句是what 引导的主语从句，注意what在句中并非疑问词，而是连接代词。在该句中使用名词性从句，起到一定的强调作用。
•第二句是 that引导的主语从句，注意that放在句首，所以不能省去，这使得句子成分明确。
• 第三句是由it作形式主语，that引导的主语从句放在句末，这是该类型的主语从句更为常见的结构形式。
While- class
学生活动：
1、学生重读文本“A Pineer fr All Peple”，找出文中带有主语从句的复合句。例如:
... what cncerned him mst was that farmers ften had pr harvests and smetimes even had
a serius shrtage f fd t eat.
Hw this culd be dne was a challenging questin at the time.
... whether it was pssible t develp a hybrid f self-pllinating plants such as rice was a matter f great debate.
…It is estimated that abut 60 percent f dmestic rice cnsumptin in China is cmprised f crps generated frm Yuan's hybrid strains.
What impresses peple mst abut Yuan Lngping is his nging ability t fulfil his dreams.
2、学生尝试不用主语从句，而用其他表述方式复述这些句子，体会主语从句在表达上的不
同作用。
提示：主语从句的位置比较灵活，采用不同句式可以丰富自己的表达。需要注意的是不同句式的运用要遵循英语表达的一些重要原则，如“末端重量”原则，即重要的信息可放在句末。还需让自己的表达更容易理解，如当句末已有从句时，不宜再将主语从句放在句末。另外，即使同一个意思可以用不同的句式来表达，它们表达的意义也会有细微区别。
3、学生先完成活动2的匹配练习，观察主语从句中的语序，然后翻译这五个句子，体会英汉
两种语言的特点，并结合前面找到的句子整理出主语从句的引导词，弄清句子的主语是如何经由引导词引出的。
A What wrries many peple remains an unanswered questin.
B That the lifestyle is slwer and healthier is an imprtant tpic fr us t research.
C Hw we can find a suitable slutin t prduce sufficient fd while keeping the envirnment safe is that these chemicals may even cause cancer.
D When these wheat farmers will jin this pilt experiment these vegetables can even be planted withut any sil thrugh this new technlgy.
E It amazed all f us that is the reasn why sme peple prefer t live in the cuntry rather than in the city.
4、学生完成活动3，找出短文中的主语从句，体会从句在语篇连贯中的作用，并讨论是否可
以把主语从句改写成其他的表达方式，以及改写后的语义变化和效果。同时，教师还应引导学生关注这篇短文和农业主题的关联性——语篇反映了人们在生活中对绿色农业的态度。
Grandma has been cmplaining abut the vegetables sld in the supermarket, which have been grwn using chemical fertilisers. T her, that they lk beautiful n the utside is bvius. Hwever, what she is unhappy abut is the lwer nutritinal value and reduced flavur. Nw that bth f my grandparents have retired frm their jbs in the city, hw they are ging t spend their retirement is an imprtant decisin fr them. Whether they can live a healthy life is the first thing they are cnsidering. S they have made up their minds t mve t the cuntryside, where they can live a green life.
三、After-class
学生两人一组，讨论袁隆平为什么会取得成功以及他所具备的品质，利用提示框中的主语从句结构组织语言，形成有理有据的口头陈述。学生应聚焦两或三个核心品质，并陈述支撑性细节或理由。
四、Summary
