标题[Ask ]compare a sentence with of and without of
时间Wed Apr 25 15:27:51 2007
Could anybody tell me what are the difference of following two sentences?
Smallpox infection has a mortality rate of between 20 percent and 50 percent.
vs
Smallpox infection has a mortality rate between 20 percent and 50 percent.
When you will choose to add of in a sentence?
