怎样学好名词性从句？

下面是我编写的一个小故事，语篇中含有各种名词性从句，请找出来：　　　　

Our teacher wondered why Tom had not attended his lessons for a few days. It was said that he had asked for leave. What surprised the teacher most was that Tom was suffering a very serious disease. 　　

His doctor suggested that he should be sent to the hospital for further medical treatment. Tom became relieved when the news that his disease was not deathful was announced last week. However, the problem that he later developed another rare heart disease bothered the doctors and his parents. Yesterday the doctors made the decision that Tom should be operated on in no time. The fact that Tom’s illness got worse disappointed his parents and all his friends. The doctors hold the belief that the operation might lead to many important scientific breakthroughs. 　　

But then the question came to their minds whether the operation would be successful. Besides that, there was also a different opinion about the question whether Tom and his parents would agree to the operation. Finally, after several discussions, the doctors and Tom’s parents reached an agreement that the operation would be performed next day.(www.hxen.net)
