Question

用定语从句在这几个简单句中选择合并成一个句子？

I often take a walk after dinner. It is my usual practice. It is known to us all. You may live up to ninety-nine years, if you take a walk after meals.

Answer 1

第一、二两句可以合并成一个含有定语从句的主从复合句，具体做法如下：用关系代词which代替 I often take a walk after dinner在定语从句里做主语，正确答案是： I often take a walk after dinner, which is my usual practice.

Answer 2

It is my usual practice that I take a walk after dinner. It is known to us all that you may live up to ninety-nine years if you take a walk after meals. 主语从句。。。发过来就是定语从句了。

Answer 3

It's known to us all that it's my usual practice that I often take a walk after dinner, which may let me live up to ninety-nine years old.
