I was told that there were about 50 foreign students studying chinese in the school,most of whom were from germany.详细分析一下句子成分，非常感谢
I was told 不是被动语态吗？

Answer 1

I was told that ......主句
I 主句的主语
was told 主句的谓语
that there were about 50 foreign students studying chinese in the school,这些统统是主句的宾语，因为是个完整的句子，所以叫做宾语从句

其中
there were 引导词
about 50 foreign students 宾语从句的主语
studying 宾语从句的谓语
chinese 宾语从句的宾语
in the school,宾语从句的地点状语
most of whom were from germany这是主句的并列句。
most of whom 并列句的主语were 并列句的系动词，也可以叫谓语。from germany并列句的地点状语
请注意，宾语从句是第一个主句的宾语。与并列句没有关系。第二个主句，也就是并列句没有宾语。

Answer 2

I was told that there were about 50 foreign students studying chinese in the school,most of whom were from germany.
that there were about 50 foreign students studying chinese in the school宾语从句，做told的宾语。
most of whom were from germany.定语从句 修饰foreign students
这句话的整体翻译是：有人告诉我说学校里大约有50名学习中文的外国学生，他们中的大多数来自于德国。
tell是及物动词，后面直接接宾语或宾语从句。

Answer 3

told 后面是宾语从句，studying...school是伴随状语，most....是非限定性定语从句
