New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth’s magnetic field, the onset of ice ages,
splitting apart continents
80 million years ago, and great volcanic eruptions.
选项
A、splitting apart continents
B、the splitting apart of continents
C、split apart continents
D、continents split apart
E、continents that were split apart
答案
B
解析
根据句意看,划线部分应该表明一种状态,是指80 million years ago的那次分离,只有这样才能与其余部分并列起来形成平行结构(第五章):磁极的颠倒,冰川时期的开始,大陆的分离及火山的爆发。由此可排除A,它是动名词词组,强调动作,与其余名词词组都不匹配;C是一个动宾词组,结构上不对应;D是一个句子,结构不对;E与原句意思相差太远,原句指那次分离,E却指被分离的大陆;因而只有B是正确的,通过在splitting前加上the表明了是发生在8亿年前的那一次分离,而不是其他时期的分离。apart of continents短语对thesplitting作修饰。
