帮我看看这句话里THAT的用法
begin its run on the qinghai_tibet railway that went indication saturday
这句话怎么翻译啊,THAT在这句话里是什么用法
我把原句写出来吧
The train arrived in xining,capital of northwest chinches provinces at 6 P.M.Sunday and began its run on the qinghai_tibet railway that went indication saturday
答
关系代词，代替前面的qinghai_tibet railway 。
答
它在青藏铁路上开始运行那天是星期六。that是关系代词代前面的its.
答
在这个句子中的that是关系代词,用来引导定语从句修饰前面的先行词railway的,在从句当中做主语.至于整句话你确定拼写正确吗?
