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 seemed as if he couldn't think of the right word.它说这是表语从句.
可是从我觉得这两个句子就是连接词不同,若从从句所做的成分来讲,如果第一个从句做主语那第二个也做主语,同理,如果第一个从句做表语那第二个也做表语.别人在讲的时候只说第一个为什么是主语从句,第二个为什么是表语从句,但是我觉得按他们分析第一个是主语从句的原因,也可以用来说明第二个也是主语从句.同样的,按他们分析的第二个是表语从句的原因,也可以说明第一句是表语从句.总之,很矛盾.请问该怎么理解啊?

第一句：It seems that…句型也可以转换成 名词或代词 ＋ seem ＋ 动词不定式的句型,其原意不变.如果动词不定式为to be ＋ 形容词时,to be往往省略.如：
It seems that he likes his new job=He seems to like his new job. 主语从句.
第二句：as if 从句的作用,【注意】它在look, seem 等系动词后引导表语从句.如： She looks as if she were ten years younger． 她看起来好像年轻了十岁. It seems as if our team is going to win． 看来我们队要胜了.
这就是你混淆的原因了!
【注意】在It seems/seemed as if...句型中,从句的谓语动词常用虚拟语气来表示所设想的事情不可能发生.例如：It seems as if she had read this novel.看来她好像看过这本小说.但如果句中的情况可能发生或可能被设想为真实,则仍然用陈述语气.例如：It seems as if our team is going to win.看来我们队要胜了.It seems as if he has learned by heart a speech written by someone else.看来他像是背了一篇由别人写的演讲稿
还有一点要提醒楼主：连接表语从句不可以用if,而用whether但as if例外.
