关于表语从句It is no longer what it was 20 years ago 这为什么是表语从句,怎么应该直接接在系动词之后啊nolonger 做什么成分? It is no longer what it was 20 years ago中的what做表语从句的什么成分 为什么 China is becoming more and more stronger.It is no longer what it used to be.分析下表语从句中what成分 Our school is no longer the school that it used to be 这句话中that是从句的表语吧?是不是可以省略 IT seems that he is very tired.是主语从句还是表语从句 1.China is no longer what it used to be.这个句子是神从句,答案说是表语从句,可是,表语从句不是直接放在be或系动词后面吗?2.We heard the news that our team had won.这句是宾语从句吗，不是同位语从句吗？ 请问 关于表语从句和主语从句的一个问题 谢谢看语法书上讲主语从句和表语从句,有一点不明白. 第一句：It seemed that Tom is not coming to the party.书上说,这是主语从句,it是形式主语. 第二句：It s No one knew whether it would happen.这是一个什么从句?主语从句还是宾语从句还是表语从句还是同谓语从句? It is no longer _______ it was 10 years ago,_______ it was so poorly equipped.It is no longer ____what___ it was 10 years ago,____when___ it was so poorly equipped.请问what引导的是主语从句还是表语从句?it是形式主语吗?后面when 关于主语从句和表语从句的一个问题 急好几本语法书上都说：It seemed that he is not coming to the party.是主语从句,it是形式主语.It seemed as if he couldn't think of the right word.是表语从句.可是我觉得这两 How long do you suppose it is since he left for Europe?— No more than half a month.这句话it is ..是不是How long do you suppose 的表语从句 关于as if引导表语从句和宾语从句.语法书中说下面这句话中as if引导的是表语从句：It looks as if it is going to rain.那么为什么有的语法书中说下面的句子中as if 引导的是壮语从句：She looks as if sh it seem+that从句是主语从句还是表语从句 'it is what you wanted '是什么句型?是表语从句吗 引导词 that可代替定语从句中的表语 that可以省略吗?Our school is no longer the school that it used to be he is not the star that he was 两句中that都可以省略吗? IT seems that he is very tired.是不是即可做主语从句又可做表语从句 （It is ）no wonder that..引导的是什么从句? it is no doubt.句型是主语从句吗
