whenever you are seeing a word you haven't known about it翻译

问题描述:

whenever you are seeing a word you haven't known about it翻译
全文,more talking with foreign people and more learning english whenever you are seeing a word you haven't known about it.这句话对吗?为什么word和you中间不加when

因为后面的you haven't known about it是用来修饰word的定语,如果一定要加也应该是加which,这样结构就更明了了,which引导一个个定语从句
