20 câu trắc nghiệm Tiếng Anh 11 Unit 5: Global warming -Reading- Global Success có đáp án

Read the text carefully then answer the following questions.

Energy is fundamental to human beings, especially to poor people – the one- third of humanity that does not have modern energy supplies like electricity, with which their life could be improve.

Many people who live in countryside have to gather fuel wood. This takes a lot of time. Moreover, it causes indoor air pollution because of heavy smoke. For many people living in rural areas in developing countries of the world, biogas is the large energy resources available and costs almost nothing. The main use of biogas is for cooking and heating. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, plant waste and animal manure cost almost nothing.

The tendency to use renewable energy sources is on the increase when non-renewable ones are running out. In the near future, people in the developing countries may use wind or sea waves as the environment-friendly energy sources.

Global warming is primarily a problem of too much carbon dioxide in the atmosphere, which acts as a blanket, trapping heat and warming the planet. Globally, the average surface temperature has increased by more than one degree Fahrenheit since the late 1800s. Most of that increase has occurred over just the past three decades.

We are overloading our atmosphere with carbon dioxide, which traps heat and steadily drives up the planet’s temperature. Carbon dioxide comes from the fossil fuels we burn for energy, such as coal, natural gas, and oil, and from the loss of forests due to deforestation, especially in the tropics.

Within the scientific community, there is no debate. Most scientists agree that global warming is happening and that human activity is the primary cause.

Global warming is already having significant and costly effects, and these consequences will only intensify as the planet’s temperature continues to rise. Global warming is accelerating the rate of sea-level rise and dramatically increasing coastal flooding risks. Climate change has significant effects on our health, including increased air pollution and a longer and more intense allergy season.

We must significantly reduce the heat-trapping emissions we are putting into the atmosphere. As individuals, we can help by taking action to reduce our carbon footprint. Tropical deforestation accounts for about 10 percent of the world’s heat-trapping emissions. Reducing tropical deforestation can significantly lower global-warming emissions and plays an integral role in a long-term solution to global warming.

Sometimes it is difficult to achieve meaningful solutions to global warming because misinformation about the truth of global warming misleads and confuses the public and makes it more difficult to carry out effective solutions.

Read the text carefully then answer the following questions.

The costs and benefits of global warming will vary greatly from area to area. For moderate climate change, the balance can be difficult to assess. But the larger the change in climate, the more negative the consequences will become. Global warming will probably make life harder, not easier, for most people. This is mainly because we have already built enormous infrastructure based on the climate we now have.

People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level more erratic rainfall, and droughts.

The crops, natural vegetation, and domesticated and wild animals (including seafood) that sustain people in a given area may be unable to adapt to local or regional changes in climate. The ranges of diseases and insect pests that are limited by temperature may expand, if other environmental conditions are also favourable.

In its summary report on the impacts of climate change, the Intergovernmental Panel on Climate Change stated, "Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.”
