习惯上后接to doing sth的名词根据英语的搭配习惯，有些名词通常要后接to doing sth，而不接to do sth，因为其中的to是介词，而不是不定式符号。这类名词比较常用的有：1. alternative 选择，可供选择的办法，替换用于alternative to doing sth，其意为“代替……的选择”。如：Unfortunately, there’s no practical alternative to driving. 遗憾的是，除了开车没有其他可行的方案。Amalgamation was the only alternative to going bankrupt. 要想不破产，唯一的选择就是联合起来。说明：have no alternative to doing sth与have no alternative but to do sth大致同义，均表示“除了做某事外没有其他的办法”，但前一结构中的to是介词，后接动词要用动名词，后一结构中的to为不定式符号。如：He had no alternative to staying at home.= He had no alternative but to stay at home. 他没有别的办法，只好呆在家里。另外，the alternative之后有时也接of doing sth，但此时不是表示“选择……代替……”而是表示同位关系。如：We took the alternative of keeping quiet. 我们选择了保持沉默。You have the alternative of marrying or remaining a bachelor. 你可以结婚也可以仍做单身汉，任你选择。2. aversion 讨厌，憎恶用于aversion to doing sth，表示“讨厌做某事”。如：He had an aversion to getting up early. 他十分讨厌早起。I have an aversion to traveling during the heat of August. 我讨厌在8月份的热浪中出去旅行。She has an aversion to eating cow liver; it makes her ill. 她对牛肝很反感，这使她恶心。3. dedication 专心致力，献身用于one’s dedication to doing sth，表示“专心于做某事”。如：His dedication to teaching gained the respect of his colleagues. 他专心致力于教学的精神赢得了同事们的尊敬。偶尔也接不定式，尤其是用于have the dedication to do sth。如：They had the dedication to continue their research in spite of the obstacles. 尽管有困难，但他们仍以献身精神继续进行研究。4. dislike不喜爱，厌恶Most of my friends feel a dislike to gambling. 我的大部分朋友都厌恶赌博。I have a strong dislike to wearing such clothes in public. 我非常不喜欢在公共场合穿那样的衣服。5. hindrance 妨碍用于a hindrance to doing sth，表示对于做某事是一个妨碍。如：Noise is a hindrance to studying. 噪音妨碍学习。Poor health is a hindrance to finding a job. 身体不好对于找工作是一个妨碍。6. key 答案，秘诀，关键用于the key to doing sth，表示“做某事的关键”。如(www.yygrammar.com)：The humble potato may be the key to feeding the world’s population. 这不起眼的土豆有可能是解决全世界人口温饱的关键。但是，若用于具体义表示“钥匙”，则可用a key to do sth。如：Have you got a key to open this door? 你有开这扇门的钥匙吗? 注意，即使是表示“钥匙”，若是用于引申义，也是用the key to doing sth。如：A chemical has been discovered that may be the key to unlocking the mysteries of Parkinson’s disease. 已经发现一种化学物质，可能是揭开帕金森氏病奥秘的钥匙。
