答案

mum,i think i`m()to get back to school
Not really,My dear.You`d better stay at home for another day or two
这一组对话显然是谈论孩子的身体状况.孩子说,我身体已经好乐,可以回学校了.所以应该选择A well enough这是说身体情况的正确用法.
How beautiful she sings!I have never heard（）
这句话的意思是：她唱得真好!我从来没听过这么好的声音.或者说,比她的声音更好的声音.这里应该用比较级来表示.应该选择B a better voice.
