Information Related to the Reading PassageClimate Change and Global Warming
The term climate change is often used interchangeably with the term global warming, but “climate change”is growing inpreferred use to “global warming”because it helps convey the fact that there are other changes in addition to risingtemperatures.
Climate change refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lastingfor an extended period (decades or longer). Climate change may result from: natural factors, such as changes in the sun'sintensity or slow changes in the Earth's orbit around the sun natural processes within the climate system (e.g. changes inocean circulation);human activities that change the atmosphere's composition (e.g. through burning fossil fuels) and the landsurface (e.g. deforestation, reforestation, urbanization, desertification, etc.)
Global warming is an average increase in the temperature of the atmosphere near the Earth's surface and in the troposphere,which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes, both naturaland human induced. In common usage, “global warming”often refers to the warming that can occur as a result of increasedemissions of greenhouse gases from human activities.Greenhouse Gases:
For over the past 200 years, the burning of fossil fuels, such as coal and oil, and deforestation
have caused the concentrations of heat-trapping “greenhouse gases”to increase significantly in our atmosphere. Thesegases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse.
Greenhouse gases are necessary to life as we know it, because they keep the planet's surface warmer than it otherwisewould be. But, as the concentrations of these gases continue to increase in the atmosphere, the Earth's temperature is
climbing above past levels. According to NOAA and NASA data, the Earth's average surface temperature has increased byabout 1.2 to 1.4oF in the last 100 years. The eight warmest years on record (since 1850) have all occurred since 1998, withthe warmest year being 2005. Most of the warming in recent decades is very likely the result of human activities. Otheraspects of the climate are also changing such as rainfall patterns, snow and ice cover, and the sea level.
Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the
concentration of greenhouse gases will change the planet's climate. But they are not sure by how much it will change, atwhat rate it will change, or what the exact effects will be.PASSAGE LEARNINGLanguage Points
1 Explanation of Difficult Sentences
1.(Para. 1) Climate change may be a big problem, but there are many little thingswe can do to make a difference.
Analysis: May can be used to introduce concession in putting forward an argument. Translation:⽓候变化可能是⼀个⼤问题,但是我们仍然可以做许多⼩事来影响它。Example: The goal you set may be nice, but it is too difficult to reach.2.(Para. 1) As we have learned, these greenhouse gases trap energy in theatmosphere and make the Earth warmer.
Analysis: As is often used to introduce an indicator of the information source,such as in as we have learned. Similar structures are: as the sayinggoes, as everyone knows, as you know, as you put it, etc.
Translation:如我们所知,这些温室⽓体把能量困锁在⼤⽓中从⽽使地球变暖。Example: As the famous Adidas ad goes:impossible is nothing.
3.(Para. 3) By turning off lights, the television, and the computer when you arethrough with them, you can help a lot.
Analysis: By is followed by a gerund, introducing a prepositional phrase of
manner. Note, by is not necessarily always translated as “通过”. Translation:你⽤完电灯、电视或电脑就随⼿关闭,那你就是帮了⼤忙!
Example: You can save energy by sometimes taking the bus, riding a bike, or simply walking.4.(Para. 8) One of the ways to reduce the amount of greenhouse gases that we putinto the air is to buy products that don't use as much energy.
Analysis: Two that-clauses are used to serve as post-modifiers of nouns: the firstone is that we put into the air, modifying greenhouse gases; The second
that-clause is that don't use as much energy, modifying products. Note:In translation, the noun phrase products that don't use as much energycan simply be translated into “节能产品”, instead of “不消耗那么多能量的产品”。
Translation: 减少排放到空⽓中的温室⽓体的⽅法之⼀就是购买节能产品。Example: Join a national or local environmental group that is fighting the climatecrisis every day.2 Important Words
