Question

1（what) a foreign language (is)is quite clear帮忙分析句子成分,为何两个is
2 then Mr smith told me (why what)he was doing was very Important这是宾从吗?why是副词可以与连词连接吗?

Answer 1

1.what a foreign language is是主语从句第二个is后面是表语.句子意思为：外语是什么很清楚.
2.我把what he was doing 换成the meeting你能看明白吗?Mr smith told me (why the meeting )was very Important原句中what he was doing 是宾语从句的主语.也就是说宾语从句中是由一个主语从句充当主语的.
