[答案与解析]
1. B。不定式的被动语态作状语。表示没有预料到的情况或结果；句意为“晚校后，那焦虑的孩子多次要爬墙，结果每次都被学校门卫逮住。”
2. D。本题考查不定式的否定结构作宾语。动词invite发生在谓语动词thought之前，应用完成时，故答案为D。句意为“舞会很成功，但我认为没邀请你很遗憾。”
3. C。句意为“我还没给他写信，因为我不知道如何开头。” 疑问词+不定式短语，其作用相当于一个名词性从句，常用在某些动词如tell, know, imagine, learn, decided, forget, remember, consider, understand等后面做宾语。
4. C。此题受定式思维的干扰，很容易误选为D. 实际上，本题考查不定式作目的状语。句意为“这里的每个人将因为消防队员预防火灾使环境更安全所做的事情而感激他们，”
5. D。本题考查不定式的省略。为避免重复, 用to来替动词不定式或不定式短语。句意为“杰克，我们明天要去看老师，你一起去吗？”“真的？我想去。”
6. C。本题考查不定式作后置定语，用主动形式表被动意义。句意为“在一些老师看来，学生学习越用功，他想起要问的问题就越多。”
7. C。该题通过调整语序考查非谓语动词在固定结构中的用法。prefer后可接不定式也可接动名词，构成词组prefer doing… to doing…意为“喜欢…而不喜欢”和prefer to do…rather than do…意为“宁愿…而不愿”。句意为“他总是宁愿早点开始，而不愿凡事留到最后时刻”。
8. A。英语中有些动词如want, decide, ask, apply, choose, determine, long, fail, wish, hope, manage, offer, promise, learn, pretend, expect, refuse等只能跟不定式做宾语。句意为“起初,我们没有现成的技术资料,但也设法照样干下去了。”
9. A。不定式作宾语补足语。句意为“儿童节那天孩子们总是盼望着父母能给他们买些礼物。”
10. B。本题考查不定式的时态。不定式的一般时表示的动作通常与谓语的动作或状态同时或几乎同时发生或在它之后发生。不定式的完成式所表示的动作通常在谓语的动作或状态发生之前就已发生或完成。根据句意“通常认为中国人发明的印刷术。”答案为B。
11. B。本题考查but后面跟动词不定式的情况。当but前面有实义动词do时，后面的不定式不带to。故答案为B。句意为“我们好像只能步行回家了。”
12. A。not to speak of为固定词组，意为“更不用说”。句意为“他的朋友和同事都会难过，更不用说他的父母了。”
13. D。to tell the truth 意为“说实话”。句意为“说实话你的计划很吸引人,不过似乎行不通。”
14. C。不定式的否定结构由“not+ 不定式”构成。in order to和so as to为同义词，但so as to只能位于句中，不能位于句首。故答案为 A（注意要将 not 放在不定式符号 to 的前面）。句意为“为了赶火车，她匆匆做完了她的工作。”
15. D。根据句式“It+ be+ 形容词+ for sb. to do sth.”可排除B和C；ask与me的关系是被动的，因此用被动语态。故答案为D。句意为“被邀请在会上发言是我的荣幸。”
