Period 2 Speaking
Goals:
1. Make the Ss learn some useful words and expressions.
2. Further develop students’ speaking abilities.
3. Arouse the Ss to take better care of the earth.
Teaching procedures:
Step 1 Revision
We have known much about pollution around. What are the problems we are facing? Which one do you think is the most important? Why?
Group 1: The lack of safe and clean water.
More than 1.2 billion people lack access to clean and safe water
Providing safe and clean drinking water would save money by freeing hospital beds from patients with disease caused by dirty water.
12 percent of the world’s population uses 85 percent of its water, and these 12percent live in developed countries.
Group 2: Air pollution
Air pollution causes more than 2.7 million deaths in the world every year.
Most air pollution is caused by the burning of fuels like coal, gas and oil.
Each year tens of thousands of people die as a result of breathing polluted air.
Air pollution causes other diseases and may make it easier for children to get sick in the future.
Group 3: Poor sanitation
Over 2.4 billion people have no access to sanitation.
Every day, as many as half of all the people on the earth suffer from one of the many diseases caused by poor sanitation.
Without proper sanitation, efforts to improve health care are useless.
Group 4: Poverty
Half the world lives on less than two dollars a day.1.3 billion people live on less than one dollar a day.
In the year 2000, some 1.7 million children died as a result of poverty.
Almost 800 million people on the world do not have enough to eat.
Step 2 Speaking
1. Talking about what Ss can see in the picture.
(1) (2)
Q1: What is being piled in the picture 1?
Q2: What can coal be used for?
Q3: What is being giving off from the workshop?
Q4: What is being polluted?
Every coin has two sides. It is true with coal, which is a valuable resource that can be used to produce energy, but it can also cause serious pollution.
2. Group work: A debate Coal is/isn’t a valuable resource.
pros cons
A businessman An environmentalist
A scientist A local citizen
A local leader
… …
1. As we know, coal is a valuable resource to produce energy, but it can also cause serious pollution. We will attend a meeting and discuss the issue.
2. Four Ss get a group. You are citizen, businessman, scientist and environmentalist.
Citizen: We must burn the coal so that we can get money to develop our area as soon as possible, because…
Businessman: We should burn the coal because…
Scientist: We should spend more money on science so that we can use the coal in a better way, because…
Environmentalist: We shouldn’t burn the coal because…
3. As a local leader in this area, summarize and help the speakers decide.
4. Ask the Ss use these useful expressions:
We must make sure that… It’s clear that…
I believe that we must… I’m all for…
If nothing is done…, then… I can’t imagine that…
Sure/ certainly / absolutely It would be better if we…
Is there a better way to…?

We human beings should take good care of our planet, because it is the only place we can survive. Love the earth, love ourselves.

About World Day for Water
The United Nations General Assembly adopted resolution A/RES/47/193 of 22 December 1992 by which 22 March of each year was declared World Day for Water, to be observed starting in 1993, in conformity with the recommendations of the United Nations Conference on Environment and Development (UNCED) contained in Chapter 18 (Fresh Water Resources) of Agenda 21. States were invited to devote the Day, as appropriate in the national context, to concrete activities such as the promotion of public awareness through the publication and diffusion of documentaries and the organization of conferences, round tables, seminars and expositions related to the conservation and development of water resources and the implementation of the recommendations of Agenda 21.
hat is World Environment Day?
World Environment Day was established by the United Nations General Assembly in 1972 to raise environmental awareness and to encourage action to protect the environment.
Ⅲ. EARTH SUMMIT
In 1992, more than 100 heads of state met in Rio de Janeiro, Brazil for the first international Earth Summit convened to address urgent problems of environmental protection and socio-economic development. The assembled leaders signed the Convention on Climate Change and the Convention on Biological Diversity, endorsed the Rio Declaration and the Forest Principles, and adopted Agenda 21, a 300 page plan for achieving sustainable development in the 21st century.
The Commission on Sustainable Development (CSD) was created to monitor and report on implementation of the Earth Summit agreements. It was agreed that a five year review of Earth Summit progress would be made in 1997 by the United Nations General Assembly meeting in special session. This special session of the UN General Assembly took stock of how well countries, international organizations and sectors of civil society have responded to the challenge of the Earth Summit.

A. man did know B. man know
C. didn't man know D. did man know
答案D. 看到Not until…的句型，我們知道為一倒裝句，答案在C，D 中選一個。改寫為正常語序為，Man did not know what heat is until the early years of the 19th. 現(xiàn)在將not提前，后面就不能再用否定了,否則意思就變了。 典型例題

【重點難點解析】
1. 詞組to one’s joy的用法
詞組“to one’s joy”意思是“使人高興的是”，在句子中作狀語，不能當作句子使用；其中的名詞多為表示人的情緒的名詞如：surprise, joy, astonishment, horror, relief, satisfaction, sorrow等，如：
1)To our great disappointment, our team lost the game. 使我們大為失望的是，我們隊輸了那場比賽。
2)To the horror of everyone, the house caught fire. 使大家驚恐的是，房子著火了。
2. 過去分詞的用法
1)過去分詞在句中起形容詞或副詞的作用，但保留動詞的特征。及物動詞的過去分詞表被動動作，不及物動詞的過去分詞表完成的動作，如：fallen leaves 落葉，the polluted water 被污染了的水。
2)過去分詞的語法功能：
①作定語：
單個過去分詞作定語放于被修飾詞之前，過去分詞短語作定語放于被修飾詞之后。
例 A broken cup is lying on the ground. 地上有一只摔破的杯子。
This is the lab built in 1990. 這是1990年建的實驗室。
The canned food has gone bad. 這灌裝食品已變質(zhì)。
②作表語：
說明主語所處的狀態(tài)。
例 We were deeply moved. 我們深受感動。
She felt rather disappointed at his failure. 他的失敗令她感到非常失望。
We are determined to complete the work in time. 我們決心按時完成工作。
③作狀語：
與句子主語為動賓關(guān)系，表示原因、時間、條件、伴隨等。
例 Seen from the hill, the park looks very beautiful. 從山上看，公園看上去很美麗。
The scientist entered the room, followed by some young men. 這位科學家進了房間，后面跟著一些年青人。
④作賓語補足語，與賓語為動賓關(guān)系。
例 I didn’t know you had your hair cut. 我不知道你理了發(fā)。
We should make it known to the public. 我們應當讓公眾知道這件事。
