【参考范文】
Recently our English Club has had a debate about whether there should be policies on controlling the purchase of private cars in our city.We had different opinions.
Some people support it.They say nowadays a large number of people own private cars，which has caused many problems，such as air pollution，traffic jams and an increase of energy use.There is no doubt that controlling the number of private cars will reduce these problems.
However，others think differently.They argue that they have the right to buy cars.What’s more，if they don’t have their own car，it isn’t convenient for them to go out，whether for work or travel.
As for me，I agree with the former.In fact，we can use other forms of transport like buses，subways and bicycles.

——课文译文——
造福全人类的先驱者
袁隆平，被誉为 “杂交水稻之父”，是中国最著名的科学家之一。然而，他认为自己是个农民，因为他不断地在田间耕作，进行科学研究。确实，他瘦削但结实的身躯看起来和他为之奉献了一生的千百万中国农民一样。
袁隆平1930年出生于北京。他的父母希望他从事科学或医学方面的工作。然而，最让他担心的是，农民经常歉收，有时甚至严重缺乏食物。为了应对这一危机，他选择了学习农业，并在重庆的西南农学院接受教育。
1953年毕业后，他从事研究工作。袁隆平意识到，解决问题的办法并不是扩大农田面积，而是农民们需要提高他们已有土地上农作物的产量。如何做到这一点在当时是一个具有挑战性的问题。袁隆平坚信，可以在杂交水稻的培育中找到答案。杂交植物是一个物种的两个或多个变种之间的杂交。杂交作物的一个特点是它们的产量通常比常规作物高。然而，是否有可能培育出如水稻等自花授粉植物的杂交种，这是一个充满争议的问题。人们普遍认为这是不可能做到的。通过不懈的努力，袁隆平克服了巨大的技术难题，于1974年培育出了第一批可用于农业生产的杂交水稻。这种杂交植物使农民能够大幅度增加他们的水稻产量。
据估算，现在中国国内消费的稻米有大约60%来自袁隆平的杂交水稻品种形成的作物，这些品种(形成的作物)让中国农民每年能够生产出大约两亿吨稻米。袁隆平的创新不仅帮助养活了中国，也养活了许多其他依赖大米的国家，如印度和越南。因为他做出了不可估量的贡献，袁隆平在国内外获得了无数奖项。
考虑到杂交水稻使袁隆平变得相当富有，人们可能认为他会退休享受闲适的生活了。然而，事实远非如此。实际上，袁隆平在内心深处仍然是一位农民。作为一个土生土长的人，他不太在乎名利。相反，他大量捐款支持农业科学研究。
袁隆平给人印象最深的是他不断实现梦想的能力。很久以前，他设想水稻高至高粱，稻穗大如扫帚，而每粒稻谷大如花生。他成功地种植出一种可以养活国内外更多人口的水稻。他对 “海水稻” 的后来设想也成为了现实，并可能在中国开辟近100万平方公里的盐碱地，用于水稻生产。甚至到了晚年，袁隆平的内心仍然年轻，富有远见，大家总是激动地看他下一步的梦想。

【写佳作 背单词】
被誉为“杂交水稻之父”的袁隆平一生致力于中国农业。曾几何时，中国的粮食严重短缺。为了解决这个危机，缓解饥饿和摆脱贫穷，袁隆平确信农民能够在同样的土地上提高水稻产量。杂交种子的一个特性表明，它们可以获得比传统作物更高的产量。通过不懈的努力，袁隆平克服了巨大的困难，培育出了第一代杂交水稻，使农民能够大幅度提高产量。在内心深处，袁隆平仍然还是一个农民。身为土地之子，他不在乎名声和金钱。袁隆平虽然很富有，却没有过悠闲的生活。他关于在盐碱地种植水稻的最新设想也变成了现实。大米和小麦是中国人的主要食物，具有几乎相同的营养价值。
【参考范文】
Known as the “father of hybrid rice”，Yuan Longping devoted his life to Chinese agriculture.There was a time when China had a serious shortage of food.To tackle this crisis，alleviate hunger and get rid of poverty，Yuan was convinced that farmers could boost the yield of rice in the same field.One characteristic of hybrids showed that they could attain a higher yield than conventional crops.Through intense effort，Yuan overcame enormous difficulties to develop the first hybrid rice that enabled farmers to expand its output greatly.Deep down，Yuan was still very much a farmer.As a man of the soil，he cared little for celebrity or money.Despite his wealth，Yuan Longping didn’t live a leisure life.His latest vision for rice growing in salty land also became a reality.Rice and wheat are the main food of Chinese people，and have almost the same nutritional value.

UNIT 5 WORKING THE LAND
Part Ⅱ Learning About Language
[语法突破 精研细究]
Ⅰ.语法图解
Ⅱ.自主领悟
1．(教材原句)However，what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat.
2．(教材原句)However，whether it was possible to develop a hybrid of self-pollinating plants such as rice was a matter of great debate.
3．(教材原句)Today，it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan’s hybrid strains，and his strains have allowed China’s farmers to produce around 200 million tons of rice per year.
4．(教材原句)What impressed people most about Yuan Longping was his ongoing ability to fulfil his dreams.
5．(教材原句)It surprised the whole world that Yuan Longping had realised his dream of developing seawater rice.
我的发现：句1、4中what在从句中作________；句2中whether不充当任何句子成分，起________作用，意为“是否”；句3、5中的it作____________；that引导的从句是真正的主语，that在句中不充当任何句子成分，本身无任何意义，只起________作用。
主语
连接
形式主语
连接
Ⅲ.要点精析
一、定义
在主从复合句中充当主语的从句即为主语从句。
What made people excited was that the solar ship had completed around-the-world trip.
让人们激动的是太阳能船已完成了环游世界的旅行。
It worried the woman that her son was always playing computer games.
儿子一直在玩电脑游戏，这让这个女人很担心。
二、主语从句的连接词及其句法功能
1．连接词that和whether
(1)that在从句中不充当任何句子成分，本身无任何意义，只起连接作用，但不可省略。
That she survived the accident is a miracle.
她在事故中幸免于难简直是奇迹。
(2)whether在从句中不充当任何句子成分，起连接作用，意为“是否”，不可省略。
Whether the plan will be carried out is still unknown.
＝It is still unknown whether the plan will be carried out.
这个计划是否会实施还不知道。
2．连接代词(who，whose，whom，what，which，whichever，whoever，whomever，whatever等)
连接代词引导主语从句，在从句中可以作主语、宾语、表语或定语。
Whichever (of you)comes in first will receive a prize.
无论(你们)谁先到都可以得奖。
Who will go to the concert is not known.
不知道谁会去听音乐会。
Whatever you do in your spare time should do no harm to others.
无论你在业余时间做什么都不应该伤害其他人。
[名师点拨] who引导的主语从句表示一件“事情”，而whoever引导的主语从句指“人”。
3．连接副词(when，where，how，why等)
连接副词引导主语从句并在从句中作状语。
How this happened is not clear to anyone.
这件事怎样发生的，谁也不清楚。
When we will have a meeting is an important question.
我们何时举行会议是个重要的问题。
Where I spend my summer is no business of yours.
我在哪里过暑假不关你的事。
[即学即练1]
用适当的连接代词或连接副词填空
①______ it was done was a mystery.
②______ John was late for the class has been unexplained.
③________ part of the country he will travel to needs discussing.
④_____________ the English evening will be held has not yet been decided.
⑤_______ surprises me most is that he is too proud.
How
Why
Which
Where/When
What
三、主语从句中用it作形式主语的结构
1．It＋be＋形容词(obvious，true，natural，strange，etc.)＋主语从句．
It is important that he should know about this.
他应该了解此事这是重要的。
[名师点拨] 在“It＋be＋形容词＋主语从句”结构中，若形容词为important/necessary/strange等，主语从句中的谓语用“(should)do”结构。
2．It＋be＋名词词组(no wonder，an honour，a pity，a/no surprise，etc.)＋主语从句．
It’s a pity that he didn’t come.
很遗憾他没来。
3．It ＋be＋过去分词(said，reported，thought，expected，proved，etc.)＋主语从句．
It is suggested that the meeting be put off.
有人建议会议延期召开。
[名师点拨] 在“It＋be＋过去分词＋主语从句”结构中，过去分词若为suggested/ordered/required/advised等，主语从句中的谓语用“(should)do”结构。
4．It＋不及物动词(happen，seem，appear，remain，etc.)＋主语从句．
It seems that it is going to rain.
看起来好像要下雨。
5．It＋及物动词＋宾语＋主语从句．

It’s suggested
It seems to me
whether she will be able to come to the party
It happened that
四、主语从句中应注意的问题
1．从句要用陈述语序
What we will do next should be decided.
应该决定一下我们下一步该做什么。
2．主谓一致
(1)从句作主语时，主句的谓语一般用单数形式。
Where he will get a job after graduation has puzzled him much.
毕业后到哪儿找份工作使他很困惑。
[名师点拨] what引导主语从句时，有时主句谓语动词应与主句中作表语的名词保持一致。
What the school needs most are books.
这所学校最需要的是书。
(2)如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句时，谓语动词用单数。
When they will start and where they will go have not been decided yet.
他们将在什么时候动身以及要去哪里还没定下来。
When and where they will hold the meeting is not clear.
