根据第1段中的Global warming, greenhouse gases, destruction of forests, pollution of oceans,air可判断出A、B、D三项均为造成野 生动物灭绝的原因。 2. D 细节题。根据第2段中的but now the chan- ges are happening too quickly for them to adapt to and they are in danger of dying out completely...
Global warming, greenhouse gases, destruction of forests, pollution of oceans, air and land are all harming the environment that wild animals depend on to live. What is happening to wild animals? Many wild animals today are endangered or facing dying out as they struggle to adapt(适应) to th...

Scientists have debated about global warming for years. 科学家一直在全球变暖这个话题上争论不休。 Many have different opinions about the extent to which greenhouse gases are responsible for it. 许多人认为工厂,发电厂或机动车辆大量排放的温室气体(例如二氧化碳)是造成全球变暖的主要原因。 Greenhouse gases, ...

“Global Warming Science”). “Even though these greenhouse gases hold the heat from the sun the greenhouse effect is what keeps the Earth’s temperature suitable for life. Without the greenhouse effect Earth would be frozen and no one would be able to live on it” (“Global Warming- ...
important greenhouse gases. Here we extend recent work on halocarbons5,6by proposing an index of global warming potential for methane, carbon monoxide, nitrous oxide and CFCs relative to that of carbon dioxide. We find, for example, that methane has, per mole, a global warming potential 3.7 ...
根据第一段中Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. 当温室气体将来自太阳的热量和光困在地球大气层中,从而导致温度升高时,全球变暖就发生了。可知,文章第一段作者给出浅显易懂的例子,其目的是给读者解释...
Global warming is a reality.There’s no question that greenhouse gases are there and that they are going to increase.They have a residence(存在) time of about 300 years in the atmosphere,so it’s going to take a long time.We really have to do two things.One is that we have to live...
