请问As作从句中的主语,是代表后面整句话吗?As is known commenly,grammer is over v As is known to all.是否为从句,若是从句,那么此从句中的主语又是什么 请问 what is known as 引导的是什么从句啊? as is known to. as is known to all中的as是什么词性 is also known as...中的as是什么词性 请问：as 可以引导主语从句吗?刚看到一个句子：As is shown from the graph,…….在这as引导 Venice is known as"( )"London is known as"( AS IS KNOWN TO ALL As is known to us.和It is known to us.后面接什么啊?为啥 kunming is known as “spring city”.这句话的意思 whether he is coming is not known.是主语从句吗?拜托各位了 3Q
