常见错误

❌ 错误:The battery is discharging now.
✓ 正确:The battery is being discharged now.

“discharging”是动词的现在分词,强调正在进行的动作;而“discharged”是形容词或过去分词,描述状态。这里应使用被动语态表示电池正在被放电。

❌ 错误:He discharged from the company.
✓ 正确:He was discharged from the company.

“discharge”作为及物动词时,通常用于被动语态来表示被解除职务或合同,所以需要加上“was”构成正确表达。

近义词辨析

released

“released”更通用,指从束缚或控制中解脱,如释放囚犯或信息;而“discharged”更具体,常用于正式场合如出院、退役或放电。

The prisoner was released from jail. (通用解脱) / The patient was discharged from the hospital. (特定正式过程)

emptied

“emptied”强调清空容器或内容物,如倒空杯子;而“discharged”侧重于排出或释放过程,如放电或排液,常带技术或正式色彩。

She emptied the glass of water. (清空内容) / The battery was discharged to zero. (释放能量)
