LESSON 2: SKILLS 
I. READING 
Activity 1. Read the text about the causes and effects of counter-urbanisation. 
I. READING 
Activity 2. Read the text again and decide whether the following statements are true (T), false (F), or not given (NG), and tick the correct box. 
While urbanisation has led to fast urban growth, counter-urbanisation has resulted in the opposite situation. Counter-urbanisation happens when a great number of people move from urban areas into rural areas.This phenomenon is linked to the ‘push' and ‘pull' factors of migration. Trying to avoid overcrowded inner cities, city dwellers look for larger, cleaner and quieter houses with more land at cheaper prices in rural or suburban areas. They want to escape the air and noise pollution, and the crime in inner cities.However, counter-urbanisation causes serious problems in the shrinking cities. These cities face severe economic strain and a sharp increase in poverty. Despite declining populations, they still have to spend money maintaining infrastructure, such as roads, sanitation, public transport, etc., built for a much larger population. 
Meanwhile, villages in the countryside become increasingly urbanised, grow fast and soon lose their uniqueness and charm. Local prices go up because city migrants have more money. They earn money from well-paid city jobs and high-valued city properties. Villagers often find it more and more difficult to earn a living and provide for their families.Counter-urbanisation has caused many negative effects. Governments should find urgent short-term solutions before implementing a long-term comprehensive programme to make life sustainable for people in both urban and rural areas.

Audio script 
	 As you know, the burning of fossil fuels like coal, oil and natural gas emit greenhouse gases. That is why environmentalists insist that we use clean, renewable energy sources. Wave energy, produced by ocean surface waves, is both eco-friendly and cost-efficient. Research has suggested that ocean wave power could make a major contribution to the world’s energy resources. Scientists claim that using 1% of wave energy can provide the equivalent of 500 times the world energy consumption. With 70% of the earth’s surface covered with water, wave energy is undoubtedly a valuable source of green energy. 	However , there is the challenge of converting wave power into energy and transmitting it to shore. Building and operating wave power stations in the ocean is far more expensive and difficult than on land. Also, salt water is a very hostile environment to devices. They go rusty easily and cannot last as long as those on shore. Sea waves make energy harvesting even harder by moving up and down most of the time. 	Viet Nam has a long coastline with great potential for producing wave energy. Hopefully, advancements in renewable energy technology will soon allow us to exploit wave energy effectively and efficiently.

IV. WRITING 
Activity 5. Write meaningful sentences about the pros and cons of solar energy. Use the words given. 
4. solar panels / expensive / use rare / special materials / technology / store solar energy / costly /. 
Solar panels are expensive as they use rare and special materials, and the technology used to store solar energy is costly. 
5. solar energy / not always available / access / sunlight / limited / certain times /. 
Solar energy is not always available since access to sunlight is limited at certain times. 
6. although / greener / fossil fuels / production / solar panels / emit / greenhouse gases /. 
Although it is greener than fossil fuels, the production of solar panels may emit some greenhouse gases. 
IV. WRITING 
Activity 6. Use the ideas in 5 (and your own ideas) to write an essay of 180 – 250 words about the pros and cons of solar energy. 
You can start your essay like this:  Nowadays, it has become necessary to use green technology with green renewable energy sources. Among all green energy sources, solar energy is the most important renewable energy source.  First of all,... 
Nowadays, it has become necessary to use green technology with green renewable energy sources. Among all green energy sources, solar energy is the most important renewable energy source, which has both advantages and disadvantages.  First of all, solar energy comes directly from the sun and this abundant renewable energy source is sustainable. In general, this type of energy is environmentally friendly and does not cause pollution. Another advantage is that solar energy is available everywhere in the world, not only in hot and sunny countries near the Equator. Furthermore, it is very quiet because solar energy devices do not have any moving parts.  However, solar energy is not cheap. Solar panels are expensive to produce as they use rare and special materials. In addition, the technology used to store solar energy is costly. A further disadvantage is that solar energy is not always available since access to sunlight is limited at certain times. Furthermore, although it is greener than fossil fuels, the production of solar panels may emit some greenhouse gases.  In short, there is no energy source that is completely risk-free. 
 However , the pros of solar energy as a renewable energy source 
 outweigh the cons. I hope that further development of green 
 technology will soon eliminate the disadvantages.
