Now that both of my grandparents have retired from their jobs in the city, how they are going to spend their retirement is an important decision for them.

That Yuan Longing has developed hybrid rice to tack the crisis of the hunger of the world population is well known. Whether we can become a person like him depends on our intense effort.
Step 2: Learn subject clauses
在英语中，有的从句在复合句中的作用相当于名词，称作名词性从句。
在复合句中用作主语的从句叫作主语从句。
引导主语从
句的连接词
连词that ；whether（不能用if）
连接代词：who；whoever；what；whatever；which
连接副词：when；where；how；why
主语从句要用陈述句语序。

地球是圆的，这是个事实。
Whether she will win the prize is still unknown.
还不知道是否她能获奖。
Whoever is the last to leave should turn off the lights.
凡是最后离开的人应该把灯关掉。

What some scientists have found is that their long-term use can
sometimes harm both the land and people’s health.
有科学家发现长期使用（化肥和杀虫剂）有时会对土地和人体健康
造成损害。
为了避免主语显得过长，尤其是陈述句作主语从句时，可以用it作句子的形式主语，把主语从句移到句子的末尾。
It is a fact that the earth is round.
地球是圆的，这是个事实。
It is still unknown whether she will win the prize.
还不知道是否她能获奖。
It is believed that the couple have left the country.
据信那对夫妇已经离开了这个国家。
