区别是：have a try仅仅表示试一下。try again强调再次尝试。例句：圆烂have a try1、I will have a try even though I should fail. 哪怕失败，我也要试亩余一下。2、Let me have a try at it. 让我橘耐漏试一下。3、You might as well have a try.; Why not have a try? 你何妨试一试。try again1、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？
