1、2019高考英语二轮专题强化典题精析阅读理解13Its true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. Theres also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summ

2、ary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”You may not believe that humans could change the planets climate, but the basic science is well understood. Each year, billions of tons of greenhous

3、e gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible(看不见旳) blanket.Of course, the earths climate has always been changing due to “natural” factors such as volca

4、nic eruption（熔化） or changes in solar, or cycles concerning the Earths going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere not the warming we would expect fr

5、om other possible causes.Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why arent carbon dioxide and the

6、 other greenhouse gases producing the warming that basic physics tells us they should be?”The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths one with human influence and one without. That obviously isnt pos

7、sible, and so most scientists are careful not to state human influence as an absolute certainty. 1. In most scientists opinion, the global warming is mainly caused by _.
