strokes tend to peak
问题描述：
strokes tend to peak
This could also explain why deaths from
heart attacks and strokes tend to peak on a Monday morning as there are 20% more
heart attacks on Mondays than on any other day.
答
这也可以解释为什么心脏病和中风的死亡率在周一早晨趋向顶点,因为在周一心脏病发病率比一周中的其他日子高出了20%
stroke中风
原句中explain...宾语从句,由why引导
在宾从中,deaths是主语,from heart attacks and strokes对deaths起修饰限定的作用,相当于deaths的定语,tend to为谓语动词
as引导了原因状语从句
