Step 4. Note making
Tell the students to read the text more carefully to find out the specific information. Then fill in the blanks with appropriate information from the text. After they have finished the work, get some students to yell out their answers to the rest of the class.
Step 5. Language points
(1) 5. It is thought that one billion people, that is half the world's workers, earn their living by farming. 据认为有十亿人，也就是全世界劳动人口的一半，是靠务农谋生的。
① 本句的句型结构是 It is thought + that-clause。其中的 it 是形式主语，代替真正的主语 that-clause。在这个that-clause 中有一个插入句(that is half the world's workers)，用以说明前面的one billion people.
It is thought + that-clause 的意思大体相当于 People think + that-clause。（人们认为......，据认为......）。例如：
It is thought that our basketball team will certainly win. (= People think that our basketball team will certainly win.)
据认为（人们认为），我们的篮球队肯定会获胜。
It is thought + that-clause 句型结构中的谓语动词 think 还可以
换用下列动词：
believe, know, report, say, suggest等，构成 It is believed / known / reported /said / suggested + that-clause 句型，分别相当于 People believe/know/report/say/suggest + that-clause的意思。
② earn one's living 是“谋生”、“挣钱过活”的意思。例如：
He began to earn his living at the age of twelve. 他12岁就开始自谋生活。
They earned their living by hunting. 他们靠打猎谋生。
She earned a hard living (by) washing ten hours a day.
她每天洗10个小时的衣服，以此维持艰苦的生活。
(2). For one thing, two thirds of the earth's surface is water, although this does provide a lot of food in the form of fish. 首先，地球表面的三分之二是水，尽管水的确提供了大量的可作食物的鱼类。
for one thing 作“首先”，“一则”解，用来列举理由。后面有时跟 for another （其次，再则）。例如：I can't go. For one thing, I have no money; for another, I have no time. 我去不成。一则没有钱，再则没有时间。
We should invite Jenny to the party. For one thing, she is fond of dancing and singing.
我们应当邀请珍妮来参加晚会，理由之一是她喜欢唱歌跳舞。
I don't want to buy the coat. For one thing, I don't like the colour, and for another, the price is too high.
我不想买这件外衣。一来我不喜欢这个颜色，再说价格也太贵了。
(3). First, it is being built on. 第一，在耕地上搞建筑。
本句中的 it 指上文的 farmland, is being built 是现在进行时的被动语态(be + being + p.p.),后跟介词 on。全句的意思相当于Various kinds of buildings are being built on the farmland.
注意：原句中的介词 on 不可省略。类似的例句如下，其中的介词不可省略。
All the most urgent matters are now being attended to. (= We are now attending to all the most urgent matters.) 最紧急的事情现在全都在处理中。
This question is being much talked about. (=People are talking much about this question.)
人们对这个在议论纷纷。

Step 1. Revision

(2) Revise the key points of the previous lesson.
Step 2. Presentation
Tell the students that this lesson will continue to tell something about the “Food Problem” in the world.
Step 3. Scanning
Tell the students to read the text carefully and answer the questions on Wb P87. Do orally with the class. Answers: See Wb P87.
Step 4. Language points
Tell the students to read the text and underline the language points. Talk about the language difficulties with the students.
(1) What can be done in order to make sure that no one in the world goes hungry?
为了确保世界上没有人挨饿，人们可以做些什么呢？
go hungry 作“挨饿”解。 go + adj. 表示“转变成......”，go 是连系动词，作“变得”解。这个结构常表示变坏。例如：
The machines go wrong. 机器出了毛病。
He went almost mad when he heard the news. 他听到这个消息时几乎发疯了。
His illness is going worse. 他的病情正在恶化。
(2). the European Union (EU) 欧洲联盟（简称欧盟）
(3). It has been proved that the way to produce the most food is to let farmers grow crops either to feed their family or to sell, whichever they choose. 事实证明，要生产出最多的粮食的办法，就是让农民种庄稼，或是为了供自家用，或是为了出售，由他们选择。
① 这是一个 it is thought that ... 的句型。从句 whichever they choose (= no matter which they choose)是让步状语从句，修饰 grow.
② whichever 在这里意思是“不论哪一个” (no matter which)，引导让步状语从句。又如：
You can either keep the book for yourself or give it to your friend, whichever you choose. 你可以把这本书留给自己或是送给朋友，悉听尊便。
It has the same result whichever way you do it.
不管你用哪种方法做这件事，结果都一样。
(4) 在课文的第三段有二个含有虚拟语气的句子：
1) If the peasants could farm the land themselves, food production would be much higher.
倘若农民能够自己种田，那么粮食产量就会高得多。
(5). They would not vote to lose their land and wealth, even if it resulted in a fairer society.使自己的土地和财产遭受损失的事，他们是不会投赞成票的，即使这样做的能导致一个更为公平的社会。第二个句子都使用了虚拟语气，即：对当前的情况作相反的假定。在这种句子中，条件从句的谓语用一般过去时（be动词用were），如第1)句中的 could farm, 第2)句中的 resulted in, 第3)句中的 were grown; 主句用 would / could / might + 动词原形。例如：
I'm busy. If I had time, I would go.
我现在很忙。如果我有时间，我是会去的。
So you have to leave. How nice it would be if you could stay a bit longer!
那么你不得不走。 要地你能多呆一会儿该多好！
If everyone in the country knew first aid, many lives would be saved.
倘若每个国民都懂急救，那么许多人的生命是可以得救的。
If I were you, I would not give up. 如果我是你，我就不会放弃。
What would happen if she were told about it?
如果她知道这事，会发生什么情况呢？
(6). Many less-developed countries are in debt because they borrowed money from richer countries in order to develop industry.
许多不太发达的国家都欠了债，因为它们从较富裕的国家借了钱来发展工业。
① less-developed 是一个“副词 + 过去分词”的结构，作定语。
② (be) in debt 作“欠债”解。例如：
Han Meimei is now is debt to Li Lei for more than one hundred yuan.
韩梅梅现在还欠李雷一百多元钱。
He was in debt when he was poor, but has been out of debt since he got rich. 他穷的时候欠过债，但变富以来就不负债了。
(7). Unfortunately they find it difficult to repay this money.
不幸的是，他们发现这笔债很难还清。
句中的it是形式宾语，用以代替后面的真正宾语(to repay this money)。形容词difficult 是宾语的补足语。英语中有一些动词 (如 consider, feel, find, think等)，后面可以跟带形式宾语 it 的复合结构。即consider / feel ... + it + adj. / n. + 不定式短语。例如：
I found it very hard to understand what he said at the meeting.
我发现很难理解他在会上讲的那些话。
Do you think it possible to finish the work in time?
你认为及时完成这项任务有可能吗？
We consider it a waste of time and money to go on with the project.
我们认为继续搞这项工作是浪费时间和钱财。
(8). Many western countries raise and butcher a large number of beef cattle. 许多西方国家饲养并屠宰大量的肉牛。
句中 raise 作“养育子女”，“饲养（牲畜）”解。例如：
Both the husband and wife had to work hard to raise their children.
夫妻二人不得不辛勤劳动来养育他们的孩子。
Another nature park has been built to raise more milu deer.
又修建了一座自然公园以饲养更多的麋鹿。
A large number of pigs and ducks are raised on this farm.
这个农场饲养了大量的猪和鸭子。
