Little Kate went to school___it rained heavily yesterday.
问题描述：
Little Kate went to school___it rained heavily yesterday.
A though
B since
为什么选B不选A?
答
though开头状语,一般在放句子前部分,且以逗号隔开.如本句可表达为：though it rained heavily yesterday,Little Katestill went to school. 同意那就是说不能像这道题一样放中间咯？？？没有表达清楚，though用法比较灵活，可以放开头作状语，一般在放句子前，中，后都可以，以逗号隔开。since没有这一用法表让步，所以选since是错误的， since有表示原因的用法但是此题不能选，意思不符合。
