Global Warming Vs Rising Sea Levels; Paragraph 1;Paragraph 1;Paragraph 2;Paragraph 2;第3段;We cannot say definitely that the 主语 谓语 that引导宾语从句 temperature rises are due to the greenhouse effect, which is a phenomenon created by which引导非限定性定语从句 the heat energy radiated by the sun and greenhouse gases normally present in the atmosphere. 我们不能肯定地说温度升高是由温室效应——一种因太阳辐射的热能和普遍存在于大气中的温室气体造成的现象——导致的。 ;In simple terms , sunlight passes through the 状语 主语 谓语 atmosphere , warming the Earth . 宾语 分词短语做状语 简而言之，阳光穿过大气层时，使地表变暖。 In turn , the Earth radiates this energy back towards 状语 主语 谓语 宾语 space . 反过来，大地再将这束能量反射回太空中。;As it passes through the atmosphere , as引导时间状语从句 greenhouse gases 主语(water vapor , carbon dioxide , methane and nitrous oxide) absorb 谓语 part of the energy宾语 , while the remainder escapes into space. while=and，充当连词连接两个分句，表示两件先后发生的事 当反射的能量穿过大气层时，温室气体（水蒸气，二氧化碳，甲烷和氧化亚氮）吸收了部分能量，剩下的则回到太空中。;This means that some of the sun’s energy 主语 谓语 that引导宾语从句 主语 becomes trapped-thus making the lower part of 系动词 表语 结果状语从句 the atmosphere , and Earth , warmer. 这就意味着太阳的部分热量被困在大气层内， 因此使得大气层下方 ，还有大地变得更暖。 Very Good;; If the atmosphere accumulated all the trapped heat, then the Earth’s temperature would just rise and rise, but it doesn’t.; The temperature only rises until the amount of infrared or long wave radiation leaving the Earth balances the amount of energy coming in from the sun.; As long as the amount of greenhouse gases in the air stays the same, and as long as the amount of heat arriving from the sun is constant, an equilibrium is established.;词汇：; This is a steady state where as much energy is lost to space as is gained from the sun.; In equilibrium ,the natural greenhouse effect maintai
