trytodo(日积月累：try TO DO something 与 try DOING some
区别：
try后面可接不定式，也可接动名词，但意思有区别。若接不定式，try的意为“事情有难度，做起来可能成功，也可能失败，尝试一下，看看结果”。
例如：
I was very tired. I tried to keep my eyes open but I couldn't. 我很累，试图睁开眼睛，但睁不开。
He tried to open his car window but he couldn't. 他试图打开汽车窗户，但没能成功。
Mary tried to be serious but she couldn't help laughing. 玛丽想严肃点儿，但还是忍不住笑。
I'll try to call him again. 我再给他打电话试试看。
We must try to spend less money. 我们必须尽量少花钱。
若接动名词，try则表示“事情不难，但不知道做起来是否到能够达理想的结果，提出解决问题的办法或建议，看看结果”。
例如：
I don't know where Alice is. 我不知道爱丽丝在哪里。
Try calling her on her cell phone. 试试给她打手机。
