短文改错对非谓语动词的考查主要涉及不定式符号 to
的有无，介词后该使用动词的什么形式(用动名词)，并列结构中几个非谓语动词是否一致，动词用作主语时用何种形式(可用动名词或不定式，但不能用动词原形)等。
真题单句归纳：
(1) I want to thank you again for have me in your home for the summer
holidays. (have改为having，因为介词后接动名词作宾语) (全国卷)
(2) I look forward to hear from you soon. (hear改为 hearing，因为其前的 to 是介词)(3)
I‘ll spend the whole weekend reading and prepare for it. (prepare 改为
preparing，因为它与其前的reading 并列，与其前所用的动词 spend 有关) (北京春季卷)
(4) He did not want share things with other people. (want 后加 to，因want
后要接不定式)
(5) Soon I began to enjoy talk to myself on paper as I was learning to
express myself in simple English. (talk 改为 talking，因为动词 enjoy 后要接动名词作宾语)
