常见错误

❌ 错误:Thallium is a common metal in daily life.
✓ 正确:Thallium is a rare metal, not commonly encountered in daily life.

错误在于夸大了铊的普遍性;实际上铊是稀有金属,日常接触较少,主要用于专业领域。

❌ 错误:I bought a thallium for my experiment.
✓ 正确:I bought some thallium for my experiment.

错误在于将thallium用作可数名词;作为物质名词,它通常不可数,应使用some或具体量词如a sample of thallium。

近义词辨析

lead

铅(lead)是另一种重金属,但更常见且毒性不同;铊(thallium)毒性更强,在电子应用中更特异。

While lead is often used in batteries, thallium is preferred for certain optical devices.

arsenic

砷(arsenic)也是有毒元素,但化学性质和用途不同;铊更常用于高科技材料,而砷在农药中更常见。

Arsenic contamination is a major issue in groundwater, whereas thallium is more linked to industrial waste.
