239. Sometimes, when I was pushed into an argument on left brain versus（相对于）right brain, or nature versus nurture（培育）, I would instantly fight fiercely on my behalf and all womankind.
译文有时，当我被卷入一些关于左脑与右脑或者天赋与培育的争论时，我会立刻为我自己和所有的女性进行激烈的抗辩。
点睛本句的主干是I would fight。when I was pushed into an argument on left brain versus right brain, or nature versus nurture为时间状语从句；instantly、fiercely和on my behalf and all womankind皆为fight的状语。
push sb. into sth.的意思是“逼迫某人做某事”，也可用作push sb. into doing sth.。如：
She was pushed into going to university by her parents. 她是被父母逼着上大学的。
on one's behalf的意思是“为某人的利益，做某人的代表或代言人”，也可用作on behalf of sb.。如：
On behalf of my parents and myself, I thank you. 我代表我的父母以及我自己向你表示感谢。
