21.原句是Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language. 正确选项为A,原句正确。 其中E选项是Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood, 解释E的错误是“Like D, this sentence attempts to attach a present-tense descriptor to a present-perfect clause.”
然而25题修改后的句子是Using accounts of various ancient writers, scholars have painted a sketchy picture of the activities of an all-female cult that, perhaps as early as the sixth century B.C., worshipped a goddess known in Latin as Bona Dea, “the good goddess.” 这样不是又犯了用present-tense 修饰present-perfect句子了吗?
