Teaching procedures:
Step 1. Revision
(1) Check the homework exercises.
(2) Revise future time by asking the students some questions about their future arrangement.
Step 2. Presentation and listening
SB Page 25, Part 1. Ask questions about the picture, and get students to tell you what they are doing. Teach the new words. Then play the tape for students to follow and tell them to answer the following questions:
① Why does the manager want to have a new factory built?
(The manager thinks his factory now is too small. It can't produce goods quickly enough for all their customers. Many of them have to wait six months for their goods. The manager hopes to build a new factory to produce more goods.)
② What’s the main problem if they build a new factory? Why?
(The problem is finding land for it. Some people don't want good farmland to be built on.)
③ What do you think is likely to happen? Why?
(The manager will persuade the government to let him build a new factory.)
Step 3. Reading
Get the students to read the dialogue and then go through the grammatical points and structures.
① Do you think our manager is going to have a new factory built? 你认为我们的经理打算新建一家工厂吗? have作为使役动词使用时常用于三种句型，如：* I had my left leg broken yesterday. (have...done可以表示不幸的遭遇)昨天我的左腿断了。
* The government had some trees cut down to widen the roads. (have...done 可以表示让……被做) 为了扩宽道路，政府叫人砍倒了一些树。

* The soldiers had the boy stand against the wall. (have...do 让……做了) 士兵们让那个男孩背靠墙站着。
② The majority of people in the town want to encourage new industry in the area. 这个城里的大多数人希望鼓励发展这个地区的工业。
1) majority 是名词，意为“多数”、“大半”、 “超过对方的票数”、“达到成年的法定年龄”。majority 作为主语时其谓语形式可以是单数，也可以是复数， 主要决定于它后面的名词中心词，如： * The majority of the machines in this factory are out of date. 这家工厂的大多数机器都已经落后。
* The majority were/was in favour of his plan. 大多数人赞成他的计划。
* He was elected president by a large majority. 他以绝对优势当选总统。
* He will reach his majority next month.下个月他达到法定的成年年龄。
2) encourage 是一个普通的及物动词，意为“鼓励”，主要用于两种结构，encourage sb./sth.和encourage sb. to do sth., 如：

* Michael encouraged his children to learn to use computers. 迈克尔鼓励他的孩子们学习电脑。
③ New jobs are needed because a number of people are out of work. 需要有新的工作(机会)，因为有一些人失业。 out of work 意为“失业”。out of 可以和一些抽象名词连用，构成一些习语，如：
Out of sight, out of mind. (谚语)离久情疏。 out of date 过时，落伍; out of fashion 过时; out of danger 脱离危险; out of question 肯定的; out of the question 不可能的,不用谈了
④ But some people don't want the farm land to be built on. 但有些人不希望在农田上搞建筑。动词不定式短语 to be built on 作the farm land 的定语。动词不定式短语作定语或作其它用时需注意主动和被动的区别，也要注意是否加介词。如：* What is to be done next? 下一步该干什么? * The doctor wanted me to be operated on. 大夫要我接受手术。
⑤ It's quite likely that a decision will be made before the end of the year. 很可能年底之前要作出决定。
make a decision 意为“作出一个决定”，如：Who made the decision to go there? 是谁作出决定去那里的?
make 常和一些名词构成固定搭配，它所表示的常常是一种创造性的劳动，如：make an invention 作出一项发明
make a speech 作讲演 make progress 取得进步 make a kite 做风筝
make contributions/achievements 作出贡献/取得成就
但也可以和一些具体的普通名词连用，如：make the bed 整理床铺 make repairs 干修理活
⑥ We just have to trust our manager. 我们只好依靠我们的经理了。
trust 是及物动词，意为“信赖”、“相信”，如：He is not the man to be trusted.
他不是一个可以信赖的人。
* Can you trust his account of what happened? 你能相信他对所发生的事的叙述吗? * Do you trust God? 你相信上帝吗? * I trust my affairs to my lawyers. 我把我的事物委托给我的律师。
trust和believe, believe in 基本同义，trust 既可以表示“相信……为事实”，也可以表示“信赖……的能力” 或“信仰”，believe 表示“相信…为事实”，believe in 表示“相信…的能力”或“信仰”之意。使用时需加以区别。

⑴ For example, many farms now use computers to control the growing conditions of vegetables and other plants. 例如，现在许多农场运用电脑来控制蔬菜和其它植物的生长情况。
1) control 意为“控制”、“管理”、“支配”。它既是动词，也是名词。Control
作为动词使用时其过去式或过去分词需写成controlled，现在分词需写成controlling。它的用法简单，只接名词或代词作宾语。如：We have to control our expenses. 我们得控制消费。
They managed to control the prices. 他们设法控制住了价格。
比较名词control的用法：
The woman has no control of her children. 这位妇女管不住孩子。
I lost control of my temper at last. 我最终禁不住发了脾气。
With the help of the PLA men, they got the floods under control. 在解放军的帮
助下，他们控制住了洪水。
2) the growing conditions 长势 condition 作为复数一般指总体状况，如：the working conditions 工作条件 the living conditions 生活状况

condition 作为不可数名词指“状态”，如：

1) water 既是及物动词，也是不及物动词，译为“(给)浇水”，如：
The gardener is watering the lawn. 那个园工正在给草坪浇水。
The dense smoke made his eyes water. 浓烟使他的眼睛流泪。
2) 注意the watering of the plants 中动词的-ing 形式和名词的动宾关系，又如：the hunting of the animals 捕猎动物 the harvesting of the rice 收割稻子
the practising of the skills 对于技巧的操练
3) as well as 意为“除……以外” 或 “不仅…… (而且)”，如：
Abilities are important as well as knowledge. 不仅知识重要，能力也重要。
We will travel by day as well as by night. 我们将日夜兼行。
The disorder is everywhere, in the cities as well as in the countryside. 到处是一片混乱，乡村和城市都如此。
Lily as well as her family is on holiday. 莉莉和她的家人正在度假。
注意最后一例中的谓语形式与 as well as 前面的主语一致，而不是与as well as后面的名词一致。使用时需加以注意。
⑶ It is possible to work out whether you will save or lose money by increasing the temperature by 1℃。你可以计算出增加1摄氏度是省钱还是赔钱。
increase 意为 “增加”，既是及物动词，也是不及物动词。increase与by连
用表示“增加了多少”，increase与to连用表示“增加到多少”。如：
Please increase the temperature to 80℃. 请将温度增加到80℃。
The number of the students in this school increased by 1000 to 4000. 这个学校
的学生增加了1,000到4,000名。
⑷ Instead of going to the bank, they will use a computer and a telephone to change money and to pay their electricity bills and so on. 他们不需要去银行而是使用电脑和电话兑换货币或付电费等。

之前不付清帐单是不对的。
Did you see the concert bill? 你看到音乐会节目单了吗?
Did the Congress pass the bill? 国会是否已通过了这项提案?
bill 所指的是未经通过的提案，如果已经通过，则称为Act，意为“法案”。
在餐馆或饭店就餐后付钱，英语中称为pay the bill。
⑸ Lights will go off if no one is in the room. 如果房间里没有人，灯会自动熄灭。 go off与lights连用，意为“熄灭”，等于go out，注意与put out的区
别，put out意为“将……熄灭”或“扑灭”，相当于一个及物动词词组。
The lights suddenly went off/out. 灯突然熄灭了。
试比较：The fire was put out soon. 火被迅速扑灭了。

He has gone off with his girl friend to Leeds. 他与女友私奔到里兹去了。

以辨认出你的声音并执行你的指令。

* Didn't you recognize my voice? 难道你没有辨认出我的声音吗?
⑺ The possibility that the majority of the labour force will work at home is often
discussed. 人们经常讨论未来大部分劳动力将有可能在家工作。
1)句中的that从句是一个同位语从句，修饰possibility， 同位语从句中的 that
只是一个连词，在从句中不担任主语、宾语或表语。因此也不可以用关系代词which去替代。而在定语从句中，that不是连词，而是关系代词，因而经常可用which去替代。试比较：
The fact that/which he told me was really surprising. (定语从句)
The fact that his son was in prison sent the old man mad. (同位语从句)
2) 经常接同位语从句的词有：order, suggestion, proposal, news, information,
idea, word(消息)，message等。如果是表示“命令”、“建议”、“请求”一类的词，后面的从句中需使用should+原形动词形式的虚拟语气，如：
* His suggestion that both sides should cease fire hasn't been accepted. 他所提的双边停火的建议尚未被接受。
* It will be much more convenient than spending a lot of time travelling to work every day. 那将会比每天花费许多时间去工作要方便得多。
much more 是程度状语，意为“……得多”， 可以修饰形容词、副词或不可
数名词。如果是可数名词，则应该用many more。如： * This computer can store much more information than that one. 这台电脑的存储量比那台大得多。
* We could see much more clearly than last time. 我们看得比上次清楚多了。
⑻ Computers will be used more and more in transport. 电脑将被越来越多地用
于交通。transport 用作名词时与transportation 意义相近，作动词使用时与carry是近义词，如：The transport/transportation of the troops will be carried out secretly. 这次军队输送将会秘密进行。
⑼ Trains will be operated by computer... 火车将由电脑来操纵……
operate是一个多义动词，如：
* The pumps are operating day and night to pump water out.为了将水排出去，水泵日夜工作。 * The company operates three factories and a mine. 这家公司经营三个工厂和一个矿。 * The new law will operate to the market. 这项新法律将会对市场起作用。 * The doctor decided to operate (on the patient) at once. 大夫决定立即(为病人)做手术。注意 operate on a patient 的结构中不可以省略on。
试比较名词的用法： * Is this rule in operation yet? 这条规则是否还有效?
* The study of the earth will enable us to see the operations of nature. 研究地球
会使我们看到大自然的造化。
* The doctor performed an operation on the wounded man's brain. 大夫给受伤的男子做了脑部手术。
⑽ As a result, costs will be reduced by as much as 90%.结果，费用将会被降低
90%。1) reduce可以被看成increase的反义词，其结构与increase 也相似，如果与by介词词组连用，则表示“减少了多少”，如果与to介词词组连用，则表示“减少到多少”。如：* We have to reduce the living expenses to buy the house. 为了买房子我们不得不降低生活开支。* He reduced his weight by 10 kilograms within two months. 他在两个月内体重减了10千克。 * She is almost reduced to a skeleton. 她瘦成了一把骨头。* The wealthy man reduced himself to begging in the end. 那个富人最终沦为乞丐。
2) as much as 在句中意为“多达”，类似的结构还有：
as early as 200 B.C. 早在公元前200年
as high as 1,567 metres 高达1,567米
as many as 2,000 people 多达2,000人
⑾ In the fields of education, health and research, computers will continue to play an important part. 电脑将在教育、卫生和研究领域里继续发挥重要作用。
1) play an important part 意为“起重要作用”。play a part也可以用play a role，
如： Electricity is playing an important part/role in our daily life. 电在我们的日常生活中起着重要作用。
The open and reform policy has played an important part/role in the development of the Chinese economy. 改革开放政策在中国的经济发展中起了重要作用。
2) field作为“领域”或“田野”使用时与介词in连用，而作为“场地”使用时与介词on连用，如：She was spraying pesticides in the fields. I believe she can make great achievements in her chosen field. 我相信她会在她所选择的领域里取得很大成就的。
⑿ The next step is to search the titles for more information. 下一步便是进一步寻找这些标题下的信息。
to search 动词不定式在句中作表语。在 plan, step, measure, idea以及all I want to do结构后面常采用动词不定式作表语。如：My plan is to climb the mountain from the northern side. 我的计划是从北边登山。
My idea is to search for the material first. 我的想法是先找材料。
⒀ They believe that the basic needs of the world's population should be satisfied first, like food and medical care. 他们觉得世界人口的基本需求，如食品和医疗，应首先得到满足。
satisfy/meet a need 满足/迎合一种需要need作名词使用时有时可用名词demand替换，如：
Electricity is in greater and greater need/demand now. 对电的需求越来越大。
need作为“需求”使用时常用作复数。如：
He earns enough to satisfy his needs. 他挣的钱足够满足他的需要。
What we should do is to meet his immediate needs. 我们所应该做的是迎合他眼下的急需。
need作为“贫穷”使用时常用作不可数名词，如：

Ex.3 The use of computers in the future
　　Computers are very useful machines. Although they can't think by themselves, they can do(or they can remember to do) what people ask them to do. So they will be widely used in the future. They can be used in many ways, such as industry and agriculture, trade and business, communication and transportation, scientific research work, education and health, space travel. They can do a great number of things as good as, if not better than, human beings. They can also help us in our personal lives, such as doing shopping and cooking, going to the bank or hospital, doing all sorts of housework, working at home. All in all, they can be used nearly everywhere. So we must do computer studies well and learn to use computers from practice.

So if the damage will come, the computer will decide to judge how to avoid it.
　　The managing system of the transportation will not need humans, either. It will be composed of many electric eyes controlling equipment and a man-made satellite a special kind of wireless equipment. The wireless equipment will pass the information that comes from the electric eyes or to the man-made satellite. And the man-made satellite will return the decision to the controlling equipment to control the country's transportation.
The transportation will become more safe and comfortable in the future.
