Their coming to help was a great encouragement to us.Our sole worry is your relying too much on yourself.Do you mind my reading your paper?They insisted on my staying there for supper.如果不是在句子开头, 这个结构常常可以用名词的普通格（或人称代词宾格）, 这比用所有格更自然一些.I don ' t mind him going.She hates people losing their temper.4）只能用动名词作宾语的动词: suggest, finish, avoid, stop, can't help, mind, admit, enjoy, leave off, require, postpone, put off, delay, practise, fancy, excuse, pardon, advise, consider, deny, endure, escape, miss5) 既可用动名词, 也可用不定式作宾语的动词: love, like, hate, dislike, begin, start, continue, intend, attempt, can' t bear, propose, want, need, remember, forget, regret, neglect, try, deserve, c'ant afford 等.有时两种结构之间意义差别不大, 有时却有不同的意思. 在remember, regret, want, try 等词后差别是比较明显的.I remember seeing her once somewhere.I must remember to take my notebooks with me.I regret not having accepted your advice.I regret to say I haven ' t given you enough help.She doesn 't want (need) to come.The house wants (needs) cleaning.We must try to get everything done in time.Let ' s try doing the work some other way.6) 悬垂修饰: 分词作状语时, 表示的必须是主语的一个动作或状态.Walking through the park, we saw a lot of flowers.
