reduce是一种主观的减少、降低,主语是使减少的外力,to make something smaller or less in size,amount,or price；
decrese是一种客观的减少、下降,主语是减少的东西（size,amount,or price etc.）,to go down to a lower level,or to make something do this.

Answer 3

decrease ,reduce 一般含义为“减少”。
decrease 比较普通，如果用词不讲究，可以代替reduce。decrease (名词亦为decrease,但重音在第一个音节上)强调数目或使人不快之物的逐渐减少。
如:to decrease the number of working hours,to decrease traffic accidents.
The workmen want to decrease the number of working hours and increase pay.
工人要求减少工作时间而增加工资。
reduce 可以表示尺寸、数量、程度或强度的减少，词义引伸之后，可以表示地位、处境、状况的降低。如:to reduce the speed,to reduce household expense,to be reduced to tears,to be reduced to ashes.
This greatly reduced the speed of the ship ,for there was danger that if she travelled too quickly,this rudder would be torn away.
