我对66题有疑问,
66. 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
(B) Covering 71 percent of Earth’s surface and playing an essential role in maintaining the
conditions for human existence on land, the oceans moderate
(C) The oceans cover 71 percent of Earth’s surface and play an essential role in maintaining
conditions for human existence on land, and by 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
B选项,og解释为 This version of the sentence is ungrammatical; and giving . . . suggests
that this is part of a series of participial phrases, but it is not.
我不懂前半句的解释,我觉得如果只看句子结构不看句意的话,并不觉得有ungrammatical的地方,covering和playing做现在分词短语修饰主句主语the oceans, 然后moderate是主句的谓语动词, 整个句子的结构是正确的啊,为什么会有问题?求解答!谢谢!
