英语语法问题-请从语法成分和时态方面帮我解析下这句话 HBU energetically implements and carries out the “two-wheel-drive” strategy,through which intelligences are brought in,teachers get trained abroad,and cross-university exchange programs are conducted. 主要是“through which intelligences are brought in”这是个什么用法?
which是带介词 的关系代词 引导定语从句 并作定从中 三个并列句的 状语 也就是 through the “two-wheel-drive” strategy intelligences are brought in, teachers get trained abroad, and cross-university exchange programs are conducted. i 这是介词短语作状语 作谓语动词 are brought in ,get trained ,和 are conducted的 方式状语
