Greenhouse effect is a natural process that warms the Earth's surface. Water vapor, carbon dioxide, methane, nitrous oxide, ozone are greenhouse gases.
and this natural greenhouse effect is needed to keep the global ecosystem running. However, too much of these gases has a negative effect on the average temperature of the Earth. Water vapor is the most abundant greenhouse gas. It differs from other gases in having concentrations linked, not ...

3. Fossil fuel firms are misleading the public about their moves to cut greenhouse gases and curb climate change – andsocial media are hosting ads that perpetuate this “greenwashing”,researchers say. Many companies have vowed to reach the “net zero” level of greenhouse gas emissions needed ...
Unlike cars, though, air-conditioners have drawn ittle criticism for theirsocial impact emissions or energy efficiency.可知,作者认为空调是一个被忽视的行业是因为它不像汽车那样受到应有的环境影响的批评。故选D。2.推理判断题。根据第四段中The more the earth warms, the more people need them. But ...
This greenhouse effect is essential; without it, the planet would become too cold to sustain life. But since the Industrial Revolution, human activities have significantly increased the amount of greenhouse gas emissions in our atmosphere. As they remain for years or even centuries, they amplify th...
order to be truly labelled as a ‘green energy’ source. Biomass power plants use wood waste, sawdust and combustible organic agricultural waste to create energy. While the burning of these materials releases greenhouse gas these emissions are still far lower than those from petroleum-based fuels....
第一段第一句“What is the single most effective way to reduce greenhouse-gas emissions?”以及后文中“The answer is: make air-conditioners better.”答案是使空调机更好,即改善空调的冷却系统,故选C。 (2)A 解析:推理判断题。根据第二段第一句“Air-conditioning is one of the world's great ...
