为什么有It was over但没有It was ended

为什么有It was over但没有It was ended It was all over get it over还是get over it ,over是介词还是副词?有句子是I said that was OK and that I was sure she would get over it.这里的解释是,over是介词,宾语只能放在over后,但也有说over是副词,与代词连用,必须放在get和ov It's over there?为什么用over? I Thought It Was Over 歌词 his hat was pulled down over his face to protect it from the sun.明白语义上it指的是face,但语法上it指的是主语hat吧~为什么指的是face呢? 是think it over 还是 think over it ? 为什么? 单句改错,I will think over it,为什么要改为think it over,over 是副词,但还是不是很理解 为什么有think it over 而不能有think it about ? it was covered with coins there were coins all over it 这两个是同义句转换 为什么用over就不对 Where was it invented [ in ] 如果不用,为什么Who was it invented 有个by Where was it invented [ in ] 如果不用,为什么Who was it invented 有个by it is over.和it was over.的区别.究竟哪个结束了?还有这两个句子在语法上有什么区别,意思相差多远. 请问：It is over.和 It was over.哪个语法才是对的呢?如果语法都对的话,两个意思分别有什么不同? 有什么put it up 但还有get over it ,是动介还有动副短语怎么区分,宾语放在那里? Could you come (over)for it?括号填over为什么? 为什么put it on 与get over it Dld it rain when school was over yesterday
