The incidence of this disease has been greatly reduced thanks to our health care program.
A. seriousness
B. frequency of occurrence
C. mortality
D. cure rate
题目解答
答案
B. frequency of occurrence
解析
题目要求我们选择一个词来替换划线单词“incidence”，以保持句子的意思不变。划线单词“incidence”的意思是“发生(率)；影响；影响的方式”。根据句子的意思，我们需要一个词来表示“发生频率”，因此选项B“frequency of occurrence”是正确的。
