The purpose of non-REM sleep is even more mysterious. The new experiments, such as those _____ for the first time at a recent meeting or the society for Sleep Research in Minneapolis, suggest fascinating explanations for the purpose of non-REM sleep.
[A] maintained
[B] described
[C] settled
[D] afforded
参考答案
正确答案：B
19. [B] 本题测试语义搭配。句中提到在某次会议上“讲述”的试验，故选 described最为贴切。[A] maintain“主张；维持”，[C] settle“解决”和[D] afford“担负得起；供给”，均不合上下文的逻辑搭配。
