Although he is one of China’s most famous scientists时让步状语从句；for he works the land to do his research 是并列分句。

For后面可以跟分句，表示原因，但和because不同。

Because是从属从句，引导状语从句，表示直接的原因；for只是顺便带出一个事实作为陈述的理由，并不是直接的原因，也不能放在句首。

例如：Prepare to alight,for we are almost there.2.Indeed ,his sunburnt face and arms and his slim,strong body are just like those of millions of Chinese farmers,for whom he has struggled for the past five decades.句子的主语是一个较长的名词词组，his sunburnt face and arms 和his slim,strong body 由and 连接，是并列关系。

Those此处用来代替前面出现的sunburnt face and arms 和slim, strong body. For whom he has struggled for the past five decades 是非限制行定语从句。
