A. one must work hard
B. working hard is important
C. it is important to work hard
D. to work hard is necessary
选择说明理由 谢谢
參考答案:选a
To make great progress是目的状语,这句话是目的状语提前。
这句话可以这么说:one must work hard to make great progress.One表示“一个人”要和“make great progress”构成逻辑上的主谓关系,即一个人努力工作,然后“人”取得进步。因此C是错误的。
B. working hard is important 主语working hard和make great progress没有逻辑上的主谓关系;
D错误的原因同上
