He has been working on agriculture education & the research into hybrid rice since he left the institute.In the 1960s, when China was suffering from serious famine, he came up with the idea of hybrid rice, which has a high yield ( or output). Ten years later, he succeeded in inventing a new species that produced a 20 percent higher yield than common types of rice. Yuan devoted himself to the research into agriculture, & was honored by UNESCO & FAO(联合国教科文组织）. Although he is 74 years old, he is still working on the research into agriculture.Period 2 ReadingStep 1 Lead-in。

Ⅰ阅读理解AToday’s beef comes from animals raised on farms.So do chicken and pork.Butsome scientists are looking to change that.They’d like to grow just the parts that wewant to eat.Create hamburgers, for example, without any cows.Opinions differ on how best to do this.Some would start with animal cells(细胞)．Others would reach for parts of plants instead.But whatever their source is, the goals are the same：tasty meat for more people, less stress on the environment.The idea of growing just the beef, not the whole cow, has been around since at least the 1890s. And it got a bit more real in 2013. That was when Mark Post introduced his labgrown hamburger at a televised tasting(品尝会)．But the cost of that first burger was high—more than $300，000.No one expected to buy a burger that cost more than a car, let alone a small plant.Other scientists want to make “meat”from plants.These dreamers are not looking to create a better “vegetable burger”．Indeed, one of these scientists, Patrick O. Brown, doesn’t like that term at all.Vegetable burgers are made from plants and have the shape of a burger.The taste is often quite different from true meat.Brown’s company, Impossible Foods in Redwood City, Calif, instead wants to make plant burgers so delicious that even those meat eaters will enjoy them and want to take another bite.When it comes to making meat，“Animals happened to be the technology that was available 10，000 years ago，”Brown says.“We stuck with that technology.But it is unbelievably inefficient(效率低的) by any measure.”Brown believes that science can come up with something better.His team is going towards the plant path. But if the scientists can make their animal-cell-based dream affordable, he adds，“I’ll be their biggest fan.”【解题导语】本文是一篇说明文。

金老师教育培训人教版高中英语必修4 专题2.3 Unit 2 Working the land G
Unit 2 Working the landGrammar：动名词作主语和宾语一、概念动名词由＂动词原形+ing＂构成。
英语动名词是非谓动词的一种形式。
从形式上，是在动词原形的末尾加上-ing，否定形式为not doing。
它既有动词的特征，又有名词的特征，故称动名词。
它也有时态和语态的变化，如表所示。
但要注意：不及物动词没有语态的变化。
形式主动语态被动语态一般式doing being done完成式having done having been done二、动名词的特点1. 它是从动词变化而来的，所以它保留了动词的某些特征，例如它能带自己的宾语、状语等，这时就叫动名词短语；2. 顾名思义，动名词最大的特点是它相当于一个名词，因此，动名词可以在句中作主语、宾语、表语、同位语等。
因为它作为名词来使用，所以动名词也有像名词一样的所有格形式。
三、动名词的用法一、作主语1. 表示经常的、习惯性的动作或状态，谓语动词通常用单数。
☛Walking is a good form of exercise for both the young and the old. 无论对年轻人和老年人来讲，走路都是一种很好的锻炼方式。
☛Watching news on TV has become a routine for me. 在电视上看新闻已经成了我的一种日常习惯。
☛Going to Hangzhou by train takes about 16 hours. 乘火车去杭州要约16个小时。
☛Asking a woman’s age is impolite in our country. 在我们国家，问一个女人的年龄是不礼貌的。
2. 作主语时常后置，此时须用it作形式主语，用形容词或名词(短语)作表语。
常用此种情况的形容词有dangerous, worthwhile, useless等；名词或名词短语有no use, no good, fun, hard work, a hard / difficult job, a waste of time 等。

动词-ing形式作主语1．动词-ing形式作主语时，往往表示经常性、习惯性的动作，通常置于句首。
◆Saying is one thing, and doing is another.说是一回事，而做是另一回事。
◆Reading aloud is a good way to learn a language.大声朗读是学习语言的一种好方法。
(1)不定式作主语表示具体的或一次性的动作。

It is useless doing... 做……没有用。

◆He tried to avoid answering my questions.他试图对我的问题避而不答。
2．作动词短语的宾语常见的跟动词-ing形式作宾语的动词短语有：insist on, object to, be good at, be fond of, lead to, put off, give up, look forward to, feel like, devote to, get/be used to, pay attention to, be worth等。

◆They continued working/to work as if nothing had happened.他们继续工作，好像什么也没发生过。
4．在love, hate, prefer, like等动词后接动词-ing形式作宾语指经常性的动作，用不定式作宾语指具体的动作。
◆He preferred staying at home when it rained.下雨时他宁愿待在家里。
(用动词-ing形式作宾语，指每逢天下雨都待在家里。
)◆I prefer to stay at home this afternoon.今天下午我宁愿留在家里。
(用动词不定式作宾语，表示“今天下午留在家里”这一具体的动作。
)【即时演练4】——单句语法填空He likes swimming but he doesn’t like to__swim this afternoon. (swim)5．有些动词(短语)后跟不定式和动词-ing形式作宾语均可，但含义不同。

【即时演练6】——一句多译①这个问题值得讨论。
→The__question__deserves__discussing.→The__question__deserves__to__be__discussed.②这个窗户需要清扫了。
→The__window__needs/requires/wants__cleaning.→The__window__needs/requires/wants__to__be__cleaned.动词-ing形式的否定形式动词-ing形式的否定形式通常是在其前加not，带有逻辑主语时not应放在逻辑主语和动词-ing形式之间。
◆You have no excuse for not going.你没有理由不去。
◆He was punished for not having finished his homework.他因未完成作业而受到惩罚。
【即时演练7】——完成句子①Excuse me for my__not__coming__on__time(我没能按时来)．②I’m sorry for not__having__kept__my__promise(没有遵守我的承诺)．动词-ing形式的复合结构动词-ing形式的复合结构实际上是给动词-ing形式加了一个逻辑主语。
