The concentration of carbon dioxide in the atmosphere has reached 399.72 parts per million (ppm) and is likely to pass the symbolically important 400ppm level for the first time in the next few daysThe Guardian
解析 D 见第二段"In the atmosphere,carbon dioxide acts rather like a one-way mirror-the glass in the roof of a greenhouse which allows the sun’s rays to enter but prevents the heat from escaping.” 文章很明确地告诉我们二氧化碳所导致的结果。
However, plants use carbon dioxide in the process called photosynthesis. This process provides food for almost all life on Earth. Some groups that support burning oil and coal want to increase the amount of carbon dioxide in the atmosphere. They oppose international efforts to control carbon ...
文章第一段Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.告诉我们大气中二氧化碳的浓度越来越高会影响海水中化学物质的变化并可能影响...
But why is the concentration of carbon dioxide in the atmosphere steadily rising? (WHY 引导的疑问句) To blame are two factors. (不定式做主语)(First of all, in the last few centuries)(状语), (first coal, then oil and natural gas)(主语) (have been burned for)(谓语) (energy)(宾语) ...

In the atmosphere, carbon dioxide allows the sun's rays to enter but prevents the heat from escaping. According to a weather expert's prediction, the atmosphere will be warmer in the year 2050 than it is today, if man continues to burn fuel at the present rate. If this warming up took...
