Answer 1

答案：B

翻译：我们都知道：那位老医生，尽管他过去的生活非常艰苦，但他在晚年还是非常辛苦地工作。

解释：

1. 分析句子结构可知：主句主语是一个从句 ____ is known to us，主句谓语是一个系表结构，其中系动词is，而表语又是一个从句 that the old doctor still works very hard in his late life.
   

2. 该主语从句 _____ is known to us中，缺少一个表示sth的主语，所以必须用what代替并引导该从句。

3. 而表语从句中又含有一个非限制性定语从句 for _____ life was hard in the past，它修饰先行词the old doctor.

   将先行词代入定语从句，只能变化为：

   life was hard (for the old doctor) in the past

   = life was hard (for whom) in the past

   = (for whom) life was hard in the past.

4. 由此可知只有答案B为正解。
