题目

And i thought that the best way to do this was to become a flight attendant.求分析
And i thought that the best way to do this was to become a flight attendant. 求分析一下句子结构,还有为什么要用TO BECOME

答案

动词不定式作表语.如果不加TO的话,独立的动词是没法成为表语的.
I（主语） thought（谓语）that...（宾语从句）
从句：
the best way to do(主语) was（系动词）to become a flight attendant（表语）
