Unit,1,Energy and Our Planet,Book 2,Listening 1,A | Read the statements. Then listen to a talk about global warming and check () any ideas that are NOT part of the talk., Our use of fossil fuels has increased. The earth receives less sunlight because of air pollution. A very much higher average temperature leads to climate change and changes to the weather. Climate change is being driven by both natural and human-made forces. New reserves of fossil fuels will be hard to find. We need to produce more alternative energy. We can personally try to conserve energy. Changes in the way of life in rapidly developing countries will make a big impact on the worlds greenhouse gases.,,,,,,Listening 1,B | Read the statements. Then listen again and complete the sentences with what you hear.,Our demand for fossil fuels like _______ and ____________ is growing. Burning fossil fuels puts __________ into the air. When there is more heat in the earths atmosphere, __________________________ increases. Climate change can have _______________________ on peoples lives. People are starting to __________________ by trying to use less fuel.,oil natural gas,carbon,the average temperature,a negative impact,conserve energy,Our demand for fossil fuels such as oil and natural gas is growing. This growing need for energy causes us to burn more and more fossil fuels. Burning fossil fuels such as coal puts carbon into the air. Carbon dioxide, or CO2, and other gases reduce the amount of heat that goes out into space. When less heat goes out into space, it means that more heat stays in the earths atmosphere. When more heat stays in the earths atmosphere, the average temperature increases, making it warmer.,To be continued ,Listening 1,A significantly higher average temperature leads to climate change and changes to the weather. Climate change can have a negative impact on peoples lives. For example, climate change can make it difficult to grow food in some places. People are starting to conserve energy by making changes that cause them to use less fuel. For example, people are buying smaller cars. Smaller cars are more efficient because they use less gas and oil.,Listening 1,Listening 2,A | Read the statements. Then listen to a talk about energy and environment and check () the main idea you hear., Global warming is inevitable. Little can be done about it. Global warming is having a negative impact on our environment. There could be quick switches to lessen the effects of global warming. Stopping global warming requires urgent, unheard-of international cooperation. It is too big a job for us. Global warming poses a threat to our environment. There could be some practical ways we can help protect the environment.,,Listening 2,B | Read the statements. Then listen again and complete the sentences with what you hear.,Cut back on ___________ by using public transportation or walking more often. Shop at _____________ close to your home. Turn off _______________________ once you are not using them.

Then listen again and complete the sentences with what you hear.,_______________________ for your energy use each month using your energy journal. ___________________________ your lifestyle to reduce the amount of energy you use.,Set a lower target,Make small changes to,Scientists believe that the earths temperature is increasing. They believe this increase in temperature is having a negative impact on our environment. You might think that protecting the planet is too big a job for you, but it isnt. There are many small and practical ways you can conserve energy and help protect the environment. Here are some helpful tips. Cut back on driving by taking public transportation or walking more often. You will save a lot of gas if you drive to work two or three days a week instead of five! Shop at local stores close to your home.,Listening 2,To be continued ,You will drive less, so you can spend less money on gas and more money on food. Turn off lights and electronics whenyou arent using them so you dont waste electricity. Replace your old appliances like refrigerators and dishwashers with new, efficient models. Old appliances consume more energy than new ones. Keep track of the electricity and gas you use and how you use it. Write down the different activities you do that use gas or electricity and how often you do them in an energy journal.,Listening 2,To be continued ,Use your energy journal to help you set a lower target for your energy use each month. For example, if your energy bill is $100 one month, try lowering your bill to $80, or by 20 percent the next month. Try to reduce the amount of energy you use by making gradual changes to your lifestyle. You will see that making small changes each month can have a big impact on t。
