为什么这英语句子要用what
我发两个句子给大家看看.
"in 1852 the British fought the Russians in （what） became known as the Crimean War"
"（what） they can not only increase knowledge but also to catch up with the times"
以上两句都有一个what,而且都是不翻译出来的.为什么咧.如果自己要造句的时候可以不用那个吗,加一个what有什么含义
答
山人之见:"in 1852 the British fought the Russians in THAT,WHAT became known as the Crimean War"
"WHAT they can do is not only to increase knowledge but also to cathch up with the times"
答
what 引导主语从句，在从句中做宾语。
答
第一个是定语从句what作引导词,在句子中作主语
答
表示强调吧
