【分析】
本题是英语非谓语动词的语法专项练习题，核心考查不定式（含带to、不带to及否定结构）的用法，解题需牢记以下固定结构：1. It's + adj + for sb to do sth（it作形式主语，真正主语为不定式）；2. 使役动词make后接不带to的不定式作宾补；3. 表“想要、希望、选择、目的”等含义时用不定式作宾语或目的状语；4. ask/tell sb (not) to do sth（要求/告诉某人（不）做某事）；5. 感官动词hear后接不带to的不定式表动作全过程；6. “the + 最高级 + 名词 + to do sth”中不定式作后置定语。结合这些结构逐一变形括号内单词即可。
【解析】
1. 固定句型It's impossible for sb to do sth，需用不定式作真正主语，故填to finish；
2. 使役动词make的固定用法make sb/sth do sth，后接动词原形，故填taste；
3. 不定式作目的状语，表组织成立的目的，故填to help；
4. 动词want的固定搭配want to do sth，故填to fail；
5. 动词ask的固定搭配ask sb to do sth，故填to use；
6. 动词hope的固定搭配hope to do sth，故填to win；
7. 动词choose的固定搭配choose to do sth，故填to go；
8. 感官动词hear的固定用法hear sb do sth（强调动作全过程），故填sing；
9. 动词tell的否定结构tell sb not to do sth，故填not to point；
10. “the best man to do sth”中不定式作后置定语，修饰man，故填to do；
【答案】
