非谓语动词一直是英语学习的重点，学好了事半功倍，学不好危机四伏，特别是在考试中。有些动词后面只接动名词或不定式（带 to 的或不带 to 的），有些动词后面既可以接动名词，也可以接不定式，而且意思往往大相径庭，有些令人苦不堪言，就比如 try to do 和 try doing.
一、try to do (make an effort)
Try to do 表示尝试去做某事，所做之事有难度，所以需要做出努力，但是结果不一定成功，例如：
I try to complete this report by the end of the day.
我必须设法在今天结束前完成这份报告。
Have you tried to learn a musical instrument?
你试过学乐器吗？
You should try not to drink more than twice a week.
你应该试着一周喝酒不要超过两次。
He likes to try to beat his sister at chess, but she always wins.
他喜欢在国际象棋上试着打败他妹妹，但她总是赢。
The children tried to put up the tent by themselves, but in the end they needed to ask their parents for help.
孩子们试图自己搭起帐篷，但最后还是得向父母求助。
She tried to catch the bus, but she couldn't run fast enough.
她想赶上公共汽车，但跑得不够快。
二、try doing sth (as an experiment or a test)
Try doing sth 表示寻找解决问题的方法，把做某事当作一个实验或测试，且事情简单；当你 try doing 某事时，这个动作总是会成功，但它可能会或不会帮助你的总体目标。当你为了解决问题而做某事时，使用 try doing sth，例如：
I’ve tried altering this recipe so many ways, but the cake never comes out quite right.
我试过很多方法来改变这个食谱，但蛋糕总是做得不对。
解析：每次改变食谱只是当作一个实验，这个动作是简单的且每次都成功了。

解析：邀请他只是一种测试，这个动作是简单的且成功了。

解析：接通电源是只是一种测试，这个动作是简单的且很容易成功。
三、区别
1. I tried to give up chocolate, but it was too hard. I always ate when my friends offered it to me.

解析：放弃巧克力这个动作是一件非常困难的事情，所以用 try to do sth.

2. It was too hot in the room. I tried opening the window. It didn't help though, it was very hot outside .

3. Have you spoken to Rachel? No I tried calling her but the line was busy.

解析：认为打电话可能是解决问题的方法。
Have you spoken to Rachel? No I tried to call her but the line was busy.

4. 总结一下
