I passed the exam and I began to feel good about it中为什么不可以用in,with或on而用about呢?急呀,

I pasted the exam easily.还是I passed the exam easily.或者说两个都可以吗？还有是half an hour passed,还是half an hour past 我通过考试了英语怎么说：I passed the exam,I was passed the exam,I have passed the exam? ____ did i passed the exam ____ i got an A How-------(luck)!I passed the English exam I have passed the exam,and i am p___of myself. To my surprised ,I passed the exam.(改错） As a ______(结果）,I passed the exam They all passed the exam,but I didn't.They all passed the exam ___ ___.同义句转换 ___________.he passed the exam. I don't know___ A that I have passed the exam B if I had passed the examC how well I did in the exam to my great joy ,i passed the exam and got an a in it.为什么只能用joy而不能用enjoyment that is to say ,的疑问句?that is to say I have passed the exam.疑问句怎么说?is that to say I have passed the exam?还是 that is to say have i passed the exam? 在Both he and I passed the exam.和 He and I both passed the exam.中both的意思及词性. for后面可不可以接整句 例如 I am happy for I passed the exam. I passed the exam because of my friends help.改为同义句（）（）Myfriend helpIpassed the exam. I have passed the 9-rank exam for the piano这句话对不对 I have passed the 9-rank exam for the piano这句话对不对 I have passed the 9-rank exam about the piano这句话对不对
