On some occasions it is important to adhere to the conventions that characterize serious public discourse and to avoid expressions that we might use in more casual situations. 把我人都绕麻了,这破句子怎么这么长
你觉得长是因为不晓得划分句子结构,把同位语从句和并列句混在一起看了。 其实就划分成四句话,①it is important to adhere to the conventions,,②(conventions)that characterize serious public discourse,,③(it is important) to avoid expressions,,④we might use in more casual situations ②作①的定语从句,that =conventions ③和①是共用it is important的并列句 ④是expressions的同位语从句,用来进一步补充解释expressions(什么样的expressions?解释:那些我们在更随意的场合使用的expressions)
