这里: when 做插入语<但这里的句子结构不完整>. that 就是vantage point,是表示这样的结构不是一个句子. 如果去掉that,那就成了一个句子. 是的,我要表达的就是这个意思,that是修饰的vantage point,但是有个when显得很奇怪,有人说这是副词,我到感觉这样的表达不简洁,如果是打算用来修饰vantage point的话,分词即可,没必要副词。when的出现显然是另一个句子的从句,但是句子也不完整,只有一个从句插入。如果去掉that的话,就是一句句子,前面的because从句和主句非常完整,意思也有关联,则若去掉that又when引导另一个主从复合句则必须用and连接或者分号格开 大全391: 1. In large doses, analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients, which may limit their potential to relieve severe pain. (A) which may limit their potential to relieve (B) which may limit their potential for relieving (C) which may limit such analgesics’ potential to relieve (D) an effect that may limit their potential to relieve(E) (E) an effect that may limit the potential of such analgesics for relieving 此题我认为主要是意思的问题. E的意思要比C 准确. 这个题我的的非限制性定从一定是错的,就近修饰的歧异,意思就不对,一定是DE中的一个
