Ход урока:
Today we are going to discuss a very important problem, the problem which requires urgent measures from out government and from ordinary people. What problems do I mean? The mankind faces a lot of different problems nowadays, but environmental problems are the most important. Do you agree with this opinion? Why? Why not? Today our aim is to discuss the problems of our environment and to try to find some possible solutions to them.
Environmental Problems Task 1 Fill in the gaps with words derived from the words in brackets. There are many problems which (1)_______ (threat) our natural environment. Acid rain, (2)_______ (globe) warming and air and water (3)________ (pollute) are among the most serious ones. There are several ways to help improve the situation. Firstly, we should encourage (4)_______ (recycle) because it is the (5) _______ (produce) of new materials which causes the most damage. We must learn to reuse things like plastic bags and glass jars. Secondly, driving an environmentally-friendly car is also (6)_______ (help). Furthermore, joining an (7)_______ (organize) which plants trees or cleans up beaches would be a (8)_______ (prove) that you are really (9)_______ (concern) about the environment. Lastly, supporting groups such as Greenpeace, which try to prevent many (10)_______ (environment) disasters, would help to ensure that our planet will be clean and safe for the future generations.
Environmental Problems Compare these pictures using the phrases given 1) In contrast to 2) In the first/the second picture one can see 3) Compared to 4) However 5) Moreover 6) Not only ... but also 7) Although 8) On the one hand/on the other hand 9) Whereas/Whereas it is 10) While 11) As well as 12) On the contrary 13) Different to 14) To have one or two thing in common 15) In comparison to 16) In order to 17) In addition 18) Generally speaking 19) First of all 20) Not only that, but I also think 21) There are various/several/many reasons for this 22) First/Firstly, second/Secondly 23) Another significant point is that 24) Because of 25) That is why 26) In that respect 27) The result of this is 28) Another aspect/point is 29) Although it is true that ... it would be wrong to claim that 30) One could argue that ... but 9) Now let’s talk about problems of big cities. Do the task. (Slide 27 + карточка с заданием № 2 для каждого ученика)) Environmental Problems Task 2 ERROR CORRECTION Look at the text below. Some of its lines are correct, so put a tick (/) next to them. Some others include an extra word which you must cross out. The first two lines have been done as an example. 0 00 level of its air pollution and the efforts made to control 1 it. However, the “City of Angels” is not neither 2 unique nor the worst one example of a polluted 3 city. Tokyo has such a serious air pollution 4 problem that oxygen masks are been supplied to 5 policemen who they direct traffic on busy roads. Milan, 6 Ankara, Mexico City and Buenos Aires face 7 their similar problems. The task of cleaning up 8 air pollution, though yet difficult, is not 9 impossible. Use of fuels that are low in 10 pollutants and a change to very less polluting 11 forms of power generation are methods 12 currently being in used. The example 13 of London, as well as to other cities, 14 has shown that major improvements in 15 air quality can be achieved in ten of years or less. 10) Let's check the task (Slides 28 – 29) 11) Global warming is one of the most difficult problems to solve. Let’s know more about it. (Карточка с заданием № 3 для каждого ученика) Environmental Problems Task 3 Six sentences have been removed from the article. Choose from the sentences A–G the one which best fits each gap 1–6. There is one extra sentence you don’t need to use. GLOBAL WARMING As long ago as the 1960s Professor Bert Bolin predicted “global warming”, caused by an increase in the amount of carbon dioxide (CO2) in the atmosphere, would lead to significant changes in the Earth’s climate. 1 __________ But most experts now agree that the amount of carbon dioxide in the atmosphere will double from 0.03% to 0.06% in the next 50 years and that temperatures worldwide will rise by 2° Celsius. Although a temperature rise of 2° may not seem significant, the local effect may be much greater: by 2025 a rise of 10° is possible in polar regions and 4° in Northern Europe. Indeed the first effects will be felt by the end of the century-perhaps they are already being felt... But how does the greenhouse effect operate and why should such a tiny proportion of CO2 have such a harmful effect? When living creatures breathe out and when things are burned, CO2 enters the atmosphere. 2 __________But the balance of nature has been disturbed. In power stations, in factories and in cars, we are burning more and more fossil fuels (coal, oil and natural gas). Eighteen billion tons of CO2 enter the atmosphere every year. And the destruction of forests means that there are fewer trees to convert the CO2 into oxygen. 3 __________ As sunlight enters the atmosphere, the surface of the earth is warmed. Some of this heat escapes back into space, but the rest is trapped by CO2, which acts rather like the glass in a greenhouse, allowing sunshine and heat to pass in but not out again. 4 __________ As the temperature rises, the amount of water vapour in the air will increase and this, too, will absorb more of the Earth’s heat. The oceans, too, will become warmer and store more heat, so that they increase the warming effect. According to some scientists, the polar icecaps will start to melt and the oceans will expand as more snow and ice melts. Because the exposed ground, formerly covered in snow, won’t reflect the heat so well it will absorb more sunlight and this will lead to even more snow melting. Scientists predict that the level of the sea will have risen by 1/2 to 112 metres by 2050. This will affect many low-lying areas of the world – millions of people today live less than one metre above sea level. 5 __________ For Northern Europeans, the extra warmth may be welcome – but there is also likely to be increased rainfall. But many areas may suffer: the southern states of the USA can expect hotter summers and less rainfall, leading to worse conditions for agriculture, and the Mediterranean region may well be much drier and hotter than now. Many experts believe that the Greenhouse Effect will bring significant changes to the Earth’s climate, though they don’t all agree how long this will take, or what form it will take. 6 __________ A) Until recently all of this was adsorbed by trees and plants which converted it back into oxygen. B) So the amount of CO2 in the atmosphere is increasing all the time. C) Some areas may actually benefit: the higher temperatures may allow a longer growing season for example. D) At the time his predictions were regarded as science fiction. E) But it certainly looks as if the inhabitants of this planet will have to get used to living in the warmer world. F) Consequently, the temperature rises. G) Surprisingly, the amount of CO2 in the atmosphere has continued to fall. 12) Let's check the task (Slide 30) 13) Many famous people try to save our planet. What can celebrities do? Do you know any famous people who give money for Green Organization, take part in charity concerts and set good examples for young people? One of these people is Michael Jackson who wrote a well-know song about the environmental problems and created a video clip. Watch the video and say what problems the singer wants us to think about. (Просмотр видеоклипа) 14) Now let's listen to the song again and this time your task is to fill in the gaps in the lyrics. (Карточка с заданием № 4 для каждого ученика) Environmental Problems Task 4 Listen to the song by Michael Jackson and fill in the gaps EARTH SONG What about1_______, What about 2_______ What about all the 3________ That you said we were to gain...

What can we do to reduce or even solve them? |
