问题描述:

It must be kept in mind that there is no secret of success but hard work.这句话中的that是什么成分?

连接词

连词,引出各种从句,翻译时不需要翻出中文来

that 引导的是主语从句,显然是连词。
可以这样看:
That there is no secret of success but hard work must be kept in mind.

由it是形式主语,that引导的是真正的主语,所以是主语从句

!

that做定语,记在心中的内容用that来代表

这是个主语从句,it是形式主语,真正地主语是that后面的从句,that不做任何成分,不用翻译

that是主语从句的连接词
It (形式主语)must be kept (谓语)in mind (地点状语)that (主语从句的连接词)there is no secret of success but hard work.(後面全部是真正的主语)

作后面同位语的引导词,there is no secret of success but hard work 作为句子的同位语表示前面 it 的意思

it是形式主语,that后的从句时真正主语,所以tht只是连接词,不做成分。
