ENVIRONMENTAL POLLUTION In recent years the problem of environmental pollution has become a serious problem in big cities in our country. So, what are reasons and possible measures for this problem? Nowadays, we are living in a city with high population density, so domestic waste is the first reason. Then many people's social consciousness is not high. In several areas, they throw rubbish on streets, canals and rivers. It is easy for us to see rubbish of all kinds floating on the water. Moreover, uncultured people even pee in the public place. Now, let's come to other reasons. Our city is overloaded with vehicles that expel a lot of smoke and dust. This contributes to the heat of the air, and causes pollution. Besides that, in several places, trees have been cut down to have room for buildings, hotels, or supermarkets. This makes the atmosphere in our city mug and stuffy. New words:In addition, many plants and factories send out waste into canals or poisonous gas into the air. muggyLast but(adi) not nồm least, ẩm, the oi bứcdrainage system in our city is very old and downgrade, so it is always flooded whenever it rains. stuffy (adi) ngột ngạt 1. What is not the reasons of environmental pollution? A. high population density B. smoke and dust from vehicles C. domestic waste D. the new drainage system 2. What is the first reason of environmental pollution? A. domestic waste B. smoke and dust from vehicles C. population density D. rubbish on streets 3. What is the synonym of the word "consciousness"? A. awareness B. unculture C. unconsciousness D. awakeness 4. Why vehicles cause air pollution? A. Vehicles make the atmosphere in our city muggy and stuffy. B. Because they expel a lot of smoke and dust. C. Because they consume too much gasoline. D. Because many people use motorbikes and cars nowadays. 5. How is the drain system in our city?
3. A. It’s very modern. B. It's downgrade. C. It is new. D. It is very old and downgrade 2. Read the text then decide these sentences are true or false. CLIMATE CHANGE AND GLOBAL WARMING Climate change Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. The green house effect While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter. Consequences of global warming o There are two major effects of global warming: the increase of temperature on the earth by about 30 to 50C (5.40 to 90 Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below: • Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice. • Amounts and patterns of precipitation are changing. • The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased. • Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes. • Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. • Diseases like malaria are returning into areas where they have been extinguished earlier Sources: Wikipedia | Time for change Circle the correct answers. l.
