常见错误

❌ 错误:I need to change a bulb light.
✓ 正确:I need to change a light bulb.

错误:误将形容词和名词顺序颠倒。正确:在英语中,'light bulb' 是固定搭配,'light' 作为形容词修饰 'bulb',应说 'light bulb' 而不是 'bulb light'。

❌ 错误:The bulb is broken, so I'll buy a new one for it.
✓ 正确:The bulb is burnt out, so I'll replace it.

错误:用 'broken' 描述灯泡不准确,可能指物理破损。正确:灯泡失效通常用 'burnt out' 或 'blown','replace' 比 'buy for it' 更地道,表示更换动作。

近义词辨析

lamp

lamp 通常指整个灯具(包括灯座、灯罩等),而 bulb 特指灯泡部分。例如,你可以更换灯泡(bulb),但灯具(lamp)可能是一个台灯或落地灯。

bulbous

bulbous 是形容词,描述球茎状或膨胀的形状,而 bulb 是名词指具体物体。例如,'bulbous root' 指球根,但 'bulb' 本身是那个根。
