问题描述：
To get a golden medal ,______.
A,hard training is needed B,it is necessary to train hard
C,one must train hard D,it needs hard training
为什么选C
答
主语一致，one是get的主语
答
A
答
动词不定式作目的状语
答
选C, 是垂悬结构, get a golden medal这个动作是由one 发出的,所以one为主语,要放在离逗号最近的地方,看到ABCD 只有C对
答
首先这个句子是以不定式开头的,做的是表示目的的状语,但是句子必须要有主语,这三个选项里,就C选项的one可做主语,因为毕竟是（人）为了拿到金牌,所以得努力,B,D选项的主语是It（它）指物,只有C指人,懂了没?
