Results from the US National Heart,Lung and Blood Institute's study found that the odds of a child being obese increase about 14% for every five extra years of their mother's age,though why this should be so is not entirely clear.
最后从why开始怎么理解呢,so 有相关例句最好了,
Results from the US National Heart,Lung and Blood Institute's study found that the odds of a child being obese increase about 14% for every five extra years of their mother's age,though why this should be so is not entirely clear.最后从why开始
why引导原因状语从句,这个很常见.如:I still don't know why he has cheated on her.我现在还不知道为什么他要背叛她.
so代替前面(the odds of a child being obese increase about 14% for every five extra years of their mother's age)整句,就是这个现象.
为什么会如此的原因却并不十分清楚。
so在这里是指它上面所说的那个现象。
