G 【解 】根前“Cutting down the use of fossil fuels helps."并结合备选项可知 G 项是此句的递进说明,表示 要减少化石燃料的使用进而使用可再生能源,符合语境。 故选 G 。 5.D 【解析】分析本段内容可知,本段是对减少化石燃料的 使用,使用可再生能源的方式的说明,空处内容应与后文 为总分关系,结合备...
C. It uses less energy and is cheap. D. It transforms fossil fuels into ammonia. 相关知识点: 试题来源: 解析 A 解析:细节理解题。根据第二段中的“it produces more CO2 than any other chemicalmaking reaction”可知,用哈伯—博施法生产氨会产生更多的二氧化碳,会对环境有害。 答案:A...
Misuse: these fossil fuels are more likely to be misused because it is free source of energy and can be extracted by anyone, anywhere. Hazardous: the fossil fuels like coal produces carbon dioxide when burned which gives off sulphur dioxide. This is a green house gas which badly andnegatively...
One example is Kenya's 55-megawatt Garissa Solar Power Plant, financed and constructed by Chinese firms. As the largest grid-connected solar power plant in East and Central Africa, it produces over 76 million kilowatt-hours annually, reducing carbon dioxide emissions by approximately 64,000 tons...
Ethanol-burns more cleanly and produces fewer harmful greenhouse emissions(排放物)(such as carbon dioride) than oil-based fuels, so it is considered as a possible replacement.Biofuels' environmental impacts are carefully assessed by working out how much energy is used during their production , ...
A Choose the best answer.(共12分) What Is a Carbon Footprint? A carbon footprint refers to the total amount of carbon dioxide (something or somebody) lets out. How Is a Carbon Footprint Calculated? For example, driving to a nearby shop burns a certain amount of fossil fuels, which ar...
So if we burn one of these fuels, we're putting its carbon into atmosphere. Right? But in a balanced system, somewhere else in the world the same amount of carbon is going back. It gets taken in by growing vegetation. So burning biomass fuel produces sort of not-so-bad carbon. In ...
our total yearly emissions, or 73.2% to be precise, come from the energy that we use. That has a fair bit to do with our over-reliance on fossil fuels and the like, something that indicates that reducing our reliance on fossil fuels can do a lot to avert the impending climate ...
The Energy Action Network (EAN) produces an annual analysis of Vermont’s greenhouse gas emissions, renewable energy development, and emissions reductions goals. This year, they provide an in-depth analysis on a pathway forward that would transition Vermont away from fossil fuels while diversifying ...
