1．The man ________to escape from prison，but he couldn't find an effective way.
A．managed B．succeeded
C．attempted D．offered
解析：manage to do sth.设法做成了某事，由but he couldn't find an effective way 可知，“越狱”没有成功，故可排除A项；succeed常用于succeed in doing sth. 结构中，排除B项；offer to do sth.主动提出做某事，不符合句意；attempt to do sth. 尝试或企图做某事，符合题意。
答案：C
