---Covering 71 percent of Earth’s surface, the oceans play an essential role in maintaining the conditions for human existence on land, moderating---temperature by the absorption of heat and carbon dioxide, and giving pure water back to the atmosphere through evaporation.
(A) Covering 71 percent of Earth’s surface, the oceans play an essential role in maintaining the conditions for human existence on land, moderating
(D) The oceans cover 71 percent of Earth’s surface, play an essential role in maintaining the conditions for human existence on land, and moderate
(E) The oceans cover 71 percent of Earth’s surface, playing an essential role in maintaining the conditions for human existence on land, and they moderate
正确答案是A,maintaining,moderating,giving是否是作动名词和in构成介宾短语,而非现在分词呢?maintaining和moderating和giving三个两两互相并列,是上面的第4种结构?
是否三个及三个以上的成分,要表示两两平行,应该是A, B, C, ..., and X.这样的表达呢?如果ABC...X都是动词原形是否两两平行的关系也成立?即SVO, VO, VO , and VO.,不考虑语义的情况下,语法上正确吗?还是应该SVO, and VO, and VO , and VO.?或SVO and VO and VO and VO.?如果只有XY,且XY是现在分词,要表示两两平行,是否只能用X and Y(即V-ing and V-ing)?如果有XYZ,且为现在分词,要表示两两平行,应该用上面3.4.5.6.7哪种结构呢? |
