【題目】An increased concentration of carbon dioxide and certain other gases in the Earth’s atmosphere ______ global warming.

A. contributing to B. contribute to

C. contributes to D. to contribute to

【答案】C

【解析】句意：地球大氣層中越來(lái)越多的二氧化碳和其他氣體導(dǎo)致了全球變暖。分析可知An increased concentration為句子的主語(yǔ)，謂語(yǔ)動(dòng)詞應(yīng)用單數(shù)第三人稱(chēng)形式。故選C。
