1.Do not talk so loudly . Your father____ A sleeps B is sleeping C slept D had sleep

2.How many people does the doctor know who ___ of the disease?
A.are dying B.is dying C.has died D.dies
3.I___ from my brother for a long time
A.not have heard B.have not heard C.have heard not D.do not hear请问这两道题怎么解答？帮一下我，详细的说明原因

1、B 用现在进行时，表示正在进行的动作。“别说那么大声，你爸爸正在睡觉。”
2、A people在这里是复数，只有A满足
3、B 首先排除A C，因为完成式的否定放在have后动词前。for a long time暗示这里要用完成时，所以只能选择B

希望可以帮到您，不明白的可以追问哈~
