• identify as asexual
• asexual in nature

语域说明

常见错误

❌ 错误:He is asexual, so he doesn't like anyone.
✓ 正确:He is asexual, so he doesn't experience sexual attraction.

错误用法混淆了无性恋(缺乏性吸引力)与不喜欢他人(可能涉及情感或社交)。正确用法应强调性吸引力的缺失,而非一般情感。

❌ 错误:This plant is asexual because it doesn't have flowers.
✓ 正确:This plant reproduces asexually because it doesn't require pollination.

错误用法将无性(asexual)误用于描述植物外观(无花),而正确用法应聚焦于繁殖方式(无需授粉的无性繁殖)。

近义词辨析

agamic

Agamic 是更专业的生物学术语,特指无性生殖,尤其用于植物或低等生物,比 asexual 更正式且使用范围窄。

Agamic reproduction is common in ferns, while asexual reproduction can refer to various organisms.

non-sexual

Non-sexual 更泛指与性无关的事物,可能不涉及繁殖或性取向,而 asexual 在生物学中特指无性繁殖,在心理学中特指无性恋。

A non-sexual relationship might be platonic, whereas an asexual individual lacks sexual attraction entirely.
