1.It is a pleasure to talk with you.2.All of us considered him honest.
3.He made it clear that he would leave the city.

Answer 1

1.It is a pleasure to talk with you.
整句是主系表结构：S + V + P.
it是形式主语，不定式短语to talk with you是句子的真正主语。
is a pleasure是系表结构，a pleasure是名词做表语。

2.All of us considered him honest.
整句是“主语 + 及物动词 + 宾语 + 宾语补足语”结构：S + V + O + OC.
主语是All of us，considered是谓语，him是宾语，形容词honest是宾语补足语。

3.He made it clear that he would leave the city.
整句是“主语 + 及物动词 + 宾语 + 宾语补足语”结构：S + V + O + OC.
主语是He，made是谓语。
it是形式宾语，真正的宾语是that从句：that he would leave the city.
clear为形容词做宾语补足语。

宾语从句he would leave the city.是“主谓宾”结构：S + V + O.
主语he，would leave是谓语，the city为宾语。
