题目

do you think it necessary to learn to wait in line?请问如何翻译?语法结构.

答案

意思就是你认为有必要学会等待吗!语法结构就是形式宾语
Do you think it necessary to learn to wait in line .形式宾语to wait in line 就是It部分,那么在这宾语从句中主语因为是to wait in line ,写清楚就是Do you think to wait in line necessary to learn?
Do you think it is necessary to learn to wait in line 宾语从句
区别就在这里
这是形式主语的句子：it is difficult to tell the differences.真正主语是后面的不定式to tell the differences
