（动词的）不定式（英语中的动词不定式可单独使用，如 She can swim 中的 swim，或带 to，如 She likes to swim） - Modal verbs generally take the bare infinitive.
情态动词通常用不带 to 的不定式。 - The use of the split infinitive is now generally acceptable.
分裂不定式的用法现在已被广泛接受。 - You use ‘have’ to form the perfect infinitive of a verb.

Idioms
split an infinitive
- to place an adverb between ‘to’ and the infinitive of a verb, for example to say ‘to strongly deny the report’. Some people consider this to be bad English style.
使用分裂不定式（在 to 和动词不定式之间插入副词，如 to strongly deny the report，有人认为这种用法有语病）
