马修真回答：
1.不加.这里furniture是不可数名词,apieceof是用来计量不可数名词的.
2.strikesbonthehead
strikesbintheface
3.setfiretosth意思是把某物点着,使某物燃烧
没有catchfireto这个短语,只有catchfire
catchfire意思是着火,例句：Hishousecaughtfirelastnight.昨晚他家失火了.
4.watchsbdo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preventsb/sthfromdoingsth,是人prevent噪声fromincreasing,所以要用被动语态,选A
例子：
Peoplearetryingtopreventthediseasefromspreading.人们正在努力阻止疾病蔓延.
Thediseasehasbeenpreventedfromspreading.疾病的蔓延已经被阻止.
