常见错误

❌ 错误:Erbium is a verb meaning to erase something.
✓ 正确:Erbium is a noun referring to a chemical element.

错误地将erbium误解为动词'擦除',实际上它是名词,指化学元素铒,与'erase'发音相似但意义无关。

❌ 错误:I need an erbium for my homework.
✓ 正确:I need information about erbium for my homework.

erbium是不可数名词,指物质本身,不能直接用作可数物品;应使用'information about erbium'等表达。
