“chalkboard” 指“黑板;粉笔板”,通常是用粉笔书写、用板擦擦除的板面(多见于教室)。也常用来泛指教学或会议场景中的板书工具。
/ˈtʃɔːkˌbɔːrd/(美式常见)
/ˈtʃɔːkbɔːd/(英式常见)
The teacher wrote today’s homework on the chalkboard.
老师把今天的作业写在黑板上。
Although the classroom had new computers, the professor still explained the proof step by step on the chalkboard, filling it with formulas.
尽管教室里有新电脑,教授仍然在黑板上一行一行地讲解证明过程,把整块黑板都写满了公式。
“chalkboard” 由 chalk(粉笔) + board(板子) 组成,是一种非常直观的复合词:用粉笔写字的板。随着教学工具发展,现代也常见 “whiteboard(白板)”,但 “chalkboard” 仍用于描述传统黑板或强调“粉笔书写”的场景。
