英语Jane spend three years in China,during which time she was learning Chinese
Jane spend three years in China,during which time she was learning Chinese.我就是搞不懂,为什么during which =when后还要加time,
答
Jane spent three years in China, during which time she was learning Chinese. 相当于Jane spent three years in China, and during that time she was learning Chinese.
答
during which 不=when
你想想，which 可以是时间，人，事物或者地方等
所以which+time才=when
答
那是在强调前面讲的在中国的三年时间.which time 在代替 前面讲过的 three years.Jane spent three years in China.Jane was learning Chinese during her three years in China.用which time来连接上面要表达的俩句...
