题型：不详难度：来源：
Carbon dioxide(CO2)_______ from burning fuels is the most common of the so-called greenhouse gases.| A．producing | B．having been produced | | C．to be produced | D．produced |
|
答案
| D |
解析
试题分析：句意：由于燃烧燃料而产生了的二氧化碳是最常见的被称为温室效应气体。整个句子的谓语动词是is，所以空格处是非谓语动词，carbon dioxide与produce之间是被动关系，故用过去分词，这里不强调produce发生的动作的时间的先后，故选D。
点评：本题难度适中。不容置疑，高考将继续加强对非谓语动词的考查，试题的特征将继续呈现出“情景化”和“设问角度的多样化”的趋势，但试题的难度将会有所控制。
即学即练：_________ what would happen, none of them could find a way out.
A. Having left wondering B. Leaving to wonder
C. Having left to wonder D. Left wondering
解析：D。考查非谓语动词的逻辑主语，由于none of them作leave的逻辑主语，它们之间形成被动关系，故选D项，其他几项都是主动形式。 |
