Learner notes
Memory Tip
联想'脉搏':pulse作动词即像脉搏一样一下一下地发出、搅打或给予,核心是'间歇性脉冲'。
Context & Register
语域:mixed 常见场景:电子/科技、医学/实验、烹饪/食品加工、文学/活力描写 pulse 作动词时语域较混合:科技、医学和烹饪等语境中多为中性书面用法,文学作品里表示“充满活力”时较具文学性;口语中较少单独用作动词。具体语气需视搭配而定。
Pronunciation & Spelling
Convulse (/kənˈvʌls/) and repulse (/rɪˈpʌls/) rhyme with pulse: they share the stressed /ʌ/ and final /ls/. Impulse contains the spelling -pulse but the stress falls on the first syllable, so it is a lookalike, not a rhyme. Else is also a lookalike: it is pronounced /els/, with a different vowel.
