"试一试"怎么说?

Give a whirl

试一试

如果碰到做事犹豫不决的人，相对他说“试一试”可以用，

give a whirl, give it a try, give it a chane.

Whirl 是“回旋、旋转”的意思， 但是在 give a whirl 中 whirl 跟 chance 和 try 一样。

除了前面三个词组外，try to do it ,try it out, go for it, see what you can do, have a go at it, take a stab at it, have a shot at it都是试一试的意思。
