文法句型

have ideas about [topic]

ideas come into one's head

用法筆記

Subject of mental verbs like 'come', 'float', 'fill', 'pass through'. Distinguish from sense 4 (opinions): here the focus is on the mental content itself, not what the person believes is true.

常見錯誤

I have a good idea in my head / mind.
💡use 'head' or 'mind' for the place where ideas live, not 'brain'.

文法句型

have ideas about how to [do something]

用法筆記

Frequently in the plural with adjectives like 'fresh', 'clever', 'wild', 'simple'. Distinguish from sense 1 (thoughts in the mind): here someone proposes a doable course of action, not just a passive mental image.

常見錯誤

💡after 'ideas for', use a gerund (-ing form), not 'to + verb'.

文法句型

ideas about [topic]

old / modern / strong ideas

用法筆記

Often paired with adjectives signalling stance (strong, firm, old-fashioned, modern, radical) and the prepositions 'about' or 'on'. Distinguish from sense 2 (plans): opinions describe what someone thinks is true or right, not what they propose to do.

常見錯誤

💡for opinions, use 'different ideas from', not 'with'.

文法句型

with the ideas of + gerund

用法筆記

Common with 'behind' (the ideas behind X = the goals motivating X) and in 'with the ideas of + gerund' (purpose). Distinguish from sense 3 (opinions): here the focus is on the goal driving an action, not on what someone believes.

常見錯誤

💡when listing several goals, use plural 'ideas' with a plural verb.

反義詞

文法句型

have no ideas (about / where / how / why) [clause]

用法筆記

Restricted to informal speech; the singular 'have no idea' is far more common in everyday English. Distinguish from senses 1-4: this is a formula expressing ignorance, not a content noun for thoughts, plans, opinions, or aims.

常見錯誤

I have no ideas what does she mean.
I have no ideas what she means.
💡after 'no ideas what / where / why', keep normal word order, not the question form.
