4、1. Greet students as usual.2. Check their workbook exercises.A material about the environment protection.People today all over the world are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by the release of completely new and often artificial subs
5、tances into the environment or by releasing greatly increased amounts of a natural substance, such as oil from oil tankers into the sea. With the development of modern industry, many of the goods and machines we need and use in our daily lives are creating a number of waste products which upset the
6、environment balance. Many of these waste products can be prevented if people pay more attention, but clearly while more and more new goods are produced and made complex, there will be new dangerous wastes to be thrown away, for example, the waste products from nuclear power stations. Many people, th
7、erefore, see pollution as only part of a larger and more complex problem.There is no doubt that much of the pollution caused could be controlled if only companies, individuals and government would make more efforts. At home there is an obvious need to control litter and waste. Food comes wrapped up
8、three or four times in packages that all have to be got rid of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuadin
9、g many of us not only to buy things we neither want nor need, but also to throw away much of what we do have. Pollution and waste combine to be a problem everyone can help to solve by cutting unnecessary buying, over consumption(消费)and careless release of the products we use in our daily lives. Step
10、 2 Writing1.Option One: Lead-in1)Collect the names of types of environment pollution.Students can give a lot on this problem.The teacher can collect the answers on the blackboard.Suggested answers:water pollution, air pollution, noise pollution, desertification, garbage in everyday life2)Give an int

12、cult for you. So you can follow the steps and example on Page 38.Show a sample:Natural DisasterEarthquakeAn earthquake is caused by a sudden slip on a fault(断层). A fault is a fracture(断裂)in the crust(地壳)of the earth along which rocks on one side have moved relative to those on the other side. Stress
13、es in the earths outer layer push the sides of the fault together, builds up and the rocks slips suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake.Earthquakes tend to be concentrated in narrow zones. There are 7 major crustal plat
14、es on earth, about 80 km(50 miles)thick, all in constant motion relative to one another. They move at between 10 and 130 mm(from less than one half to 5 inches)per year.It is estimated that there are several million earthquakes in the world each year. Many of these earthquakes go undetected because
15、they occur in remote areas or have very small magnitudes(震级). The USGS Earthquake Info Center locates 12 000 to 14 000 earthquakes each year(about 35 per day). On average, about 60 earthquakes per year are classified as significant, with 19 classified as major. A significant earthquake is one of mag
16、nitude 6. 5 or higher or one of lesser magnitude that causes casualties or considerable damage. Major earthquakes have a magnitude larger than 7. 0.2. Ask students to read through the steps on Page 38 with the whole class and ensure them to know what to write down next.And discuss the structure of t
17、heir short passage.First, briefly describe the problem with a partner, taking down notes and key words.Then, give students about 15 minutes to write down a short passage individually. Try to use the suggestions given.After that, exchange their writing with each other to correct mistakes.At last, the
18、 teacher displays some excellent writing for the whole class to enjoy.Some samples about this topic.1Many students are taking part in the practice of improving the environment through selling used paper and planting trees. They even set up a website to help others take practice in protecting the env
19、ironment. Although people care much about the environment problems but they dont know how. So some organizations also published measures to encourage public participation in environment protection. The measures tell us what we can do to protect the environment.We surely cared much about the environm
20、ent protection but didnt do much. Actually there is much we can do in our daily life. Buy less to reduce waste. Dont throw away things before we have made the most use of them. Use electricity, water and gas only when necessary. Switch them off when we dont need them. Everyone can participate in mak
21、ing the planet suitable for future generations. Everybody can join in and make our world more fantastic. Just do it!2Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both n
22、ature and human life.Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that the governments will take measures to reduce levels of harmful waste.Some governments have realized how serious the dangerous waste problem
23、is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of danger
24、ous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods. Step 3 Everyday EnglishWhile learning English, we usually encounter some confusing expressions. If we
