Although Tom is satisfied with his academic achievement ,he

Although Tom is satisfied with his academic achievement,he wonders _will happen to his family life.A.it B.that C.what D.this
答：C
译：汤姆尽管对自己学术上的成就感到很满意,却不知道自己的家庭生活会发生什么事情.
析：本题考查名词性从句的连词.it为人称代词,this为指示代词,不能引导名词性从句,排除AD.
that引导名词性从句时,只是一个标志,没有词义也不在从句中充当句子成分,故而引导宾语从句时常可省略,而这句中will happen缺少主语,所以排除B.
what是连接代词,可引导名词性从句,在从句中充当主语或宾语.
