她坚定不移地要上大学：she was determined to go to university为什么要用被动语态呢? she was determined to overcome 中的was determined是什么时态是 被动吗? Tom was heard to gou out just now.为什么要用被动语态, She determined to go that very afternoon. 上大学是go to university还是go to a/the university? 这题为什么用被动语态啊?She was taken between whether to follow her husb He was happy to be made the host.为什么不用to?不是说被动语态中要变成be made the girl was able to explain what had happened.不是被动语态为什么用was “Why to go to university”是不是病句?（意思想要表达的是“（我们）为什么上大学” make和let后面为什么主动语态不用to而被动语态要to 感官动词 为什么说它没有被动语态,又说它的被动语态要在感官动词后加to呢? 关于感官动词 为什么说它没有被动语态,又说它的被动语态要在感官动词后加to呢?
