1The boy finally __ his mother to send him to college and he was very happy. suggested/persuaded/told/attracted 答案是第二个。但是劝说不一定劝说成功为什么要高兴呢？ 2They have tried all available means __ the door,but with no luck. 答案是 to open 我的问题是这个是考查短语try to do还是考察不定式表目的呢？
解题思路： 如下
解题过程：
1The boy finally __ his mother to send him to college and he was very happy.
suggested/persuaded/told/attracted
解析：persuade“ 说服,劝服”。persuade sb. to do sth.说服某人去做某事，这个短语本身表示已经说服。如：
He persuaded her to gowith him. 他说服了她和他一块去。
如果说而不服或劝而不服，则要用try to persuade sb. to do或advise sb．to do。如：
① I have never persuaded him to take the job. = Many times I tried to persuade him to take the job, but I failed to. 我始终没有说服他接受这份工作。
suggest 不可接动词不定式的复合宾语，正确的用法是：suggest doing sth .如：
I suggested putting off the sports meet.我建议将运动会延期。
根据题干部分he was very happy可知“已经说服”，所以用persuaded。
② I tried to persuade him to do it but he wouldn't. = I advised him to do it but he wouldn't.我设法说服他做但他不肯听。
2They have tried all available means __ the door,but with no luck.
答案是 to open
解析：本题是动词不定式做目的状语。句意是：他们曾尝试所有有用的方法来开这个门，但是没有打开.
try to do sth 意思是“努力去做某事”“尽力干……”，表示想尽一切办法要把事情办成； try doing sth 意思是“尝试着干某事”“试着（用什么方法）去做某事”，表示一种试着、做做看的做法。试比较：
I'm trying to learn English well．我决心（尽力）学好英语。
I tried knocking at the back door，but nobody answered．我试着敲了敲后门，但没人回答。
注意：不论是try to do sth 还是try doing sth的用法，动词try 不用于“hope + 宾语 + 动词不定式/动名词”的结构。
最终答案：略
