如果我能勇敢一点 用英语怎么说 ？

If i was stronger...这是虚拟语气，看你要表达什么
一般用 if i can be stronger,就OK

一般都是有下句的吧

If a little bit braver,I can/could ...
上面有人说的more braver本来就是语法错误

If I could be more brave

If I were brave, I had reach the top of mountain.

几种语境
1、Just be brave
2、If i have been brave enough
3、I wonder to be more brave

if i can be a little more brave
