C.will not be prevent;to hear
D.don't prevent;to be heard
正确答案是A,
D为什么不可以?为什么不能用don't?

Answer 1

1.不加.这里furniture是不可数名词,a piece of是用来计量不可数名词的.
2.strike sb on the head
strike sb in the face
3.set fire to sth意思是把某物点着,使某物燃烧
没有catch fire to这个短语,只有catch fire
catch fire意思是着火,例句：His house caught fire last night.昨晚他家失火了.
4.watch sb do 意思是看某人做某事,而且是看全过程,并且经常带有一点监督的意思
5.prevent的用法是prevent sb/sth from doing sth,是人prevent噪声from increasing,所以要用被动语态,选A
例子：
People are trying to prevent the disease from spreading.人们正在努力阻止疾病蔓延.
The disease has been prevented from spreading.疾病的蔓延已经被阻止.
