haveatry和tryaagain的区别

区别是：

have a try仅仅表示试一下。

try again强调再次尝试。

例句：

have a try

1、I will have a try even though I should fail.

哪怕失败，我也要试一下。

2、Let me have a try at it.

让我试一下。

3、You might as well have a try.; Why not have a try?

你何妨试一试。

try again

1、You might well try again.

你无妨再试一下。

2、All I can suggest is that you just hang fire and wait a minute or two and try again.

我的建议就是，先缓一缓，等上一两分钟再试一次。

3、Why not try again?

为何不再试一下？
