Make students master the language points
Make students master the usage of “ by + - ing”.
To learn how to say numbers.

He thought that (the key to feeding people was to have more rice and to produce it more quickly.)   宾语从句
the key to sth. / doing sth.  ---的关键 to 属于“介词”  
e.g.  这就是考试失败的关键。 This is the key to failure in the exam.
  她获得成功的关键在于她的努力。The key to her success is her efforts.
   沟通时解决这个问题的关键 The key to solving this problem is communication.

He though there was only one way to do this---by crossing different species of rice plant, and then he could produce a new plant which could give a higher yield than either of the original plants.
1) (one) way to do sth. = (one)way of doing sth.
Eg. That’s not a right way to solve the problem.
I’m not happy with this way of working.
2) “which”引导定语从句 (延伸)
如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置
He paid the boy $10 for washing ten windows,most of ____ hadn’t been cleaned for at least a year. （1990）  
    　　 A. these   B. those   C. that   D. which  
　He was reading a book which he had bought from London. 他正在读一本书， 这本书是从伦敦买回来的。（关系代词which在修饰book的定语从句中充当宾语。）  
3)by crossing … 通过(杂交)的方式（grammar 2 on page35）
by+动词—ing.意为：“通过…，靠…，凭…”。
eg. Switch it by pressing this button.
I will contact you by e-mail.

4）higher比较级,比原来的任何一种作物的产量都要高
比较级与最高级的转换： Mike is more intelligent than any other student in his class = Mike is the most intelligent in his class.

5）either
either两者中任一，
both两者都
None一点都不，否定三者或三者以上或不不可数
Neither 两者都不
Both are beautiful= Both of the bags are beautiful.这两个包都好看。
　　Either (of them)is OK. (他们两个中)任何一个都行。
I like neither.(两个)我一个也不喜欢。

3. This was the breakthrough.
breakthrough: an important development that may lead to an agreement or achievement    重大进展,突破
make a breakthrough  取得突破    a major breakthrough  大突破
The key to making a breakthrough is to study hard. 取得突破的关键是努力学习。

4. 50 kilometres of rice fields were converted to growing vegetables and other cash crops.
= 50 kilometers of Rice fields were changed to grow vegetables and other cash crops.
convert (sth) to / into sth:  把…转变成；转变，改变
e.g. 那家工厂把铁转变成钢。 That factory converts iron into steel.
e.g. 我把我的美元换成了欧元。I converted my dollars into euros.

5. Following this, Yuan Longping’s rice was exported to other countries, such as ….
Following this ,非谓语动词，现在分词作状语
一般来说，ving形式表主动、进行；过去分词表被动、完成
Ving形式做状语，可表示时间，原因，结果等
时间状语（when）Hearing the news, he got frightened
.作原因状语: Being a teacher,you should help your students in every way.
做结果状语：He comes home late every evening, making his wife angry.
Mary failed all her exams, making both her parents angry.

6. As a result of Yuan Long ping’s discoveries Chinese rice production rose by 47.5 percent.
percent 不加s

7.rarely稀少地
  partly部分地，在一定程度上
nearly 几乎
mainly 主要地，大体地
