manage有应付得来,能应付得了的意思。一般来说结果是成功的。try有尝试的意思,结果通常是失败的。attempt作动词的时候,跟try意义差不多,作名词的时候有企图的意思。给你举个例子:Amanaccidentallyfellintoawell.Hewassoscaredandyelled"help".Butnooneheardit.Helookedupandthought,itwastoohightoclimbupandgetoutofitbyhimself.Hedidn'tevenattempttodoanythingbutwaiting,however,therewasnopasser-by.Lateron,hesaidtohimself,"ihavetoclimbandgetoutofhere."Hetriedacoupleoftimes,butfailed.Thenhecarefullyexaminedthewallofthewell,andtriedagain.Thistime,hemanagedouteventually.
