1. 以下动词和动词短语后只能接动名词：
常用动词：finish, mind, suggest, keep, enjoy, practice, consider, excuse, miss, escape,
resist, allow, permit, imagine, risk, delay, forbid, appreciate, understand
动词短语：give up, insist on, look forward to, it is (no )good (use, harm), object to（反
对）, get down to, devote oneself to, spend…doing, prevent…(from)…, waste…doing, have
(no) difficulty (in) doing, stick to, keep…from, stop…from
2. 动名词的几种形式要记清：doing 一般式；not doing 否定式；being done被动式；having done完成式；having been done完成被动式
3. 动词need、want、require后用动名词的主动形式表示被动意义（= to be + 过去分词）。
the baby wants washing. (= to be washed)
4. to后接动词时，to是不定式符号，应该接原形动词；to是介词应要接动名词。这一点一定要判断清楚。在“get down to开始做……；look forward to…盼望……；stick to…坚持做……；lead to…导致……；devote oneself to…献身于……；to be devoted to …献身于……；pay attention to …注意……；object to 反对做……”中，to都是介词，其后面应该接动名词。
