常见错误

❌ 错误:I need to buy some phosphates for my garden.
✓ 正确:I need to buy some phosphate fertilizer for my garden.

错误用法中'phosphates'作为可数名词复数使用,但在日常语境中,'phosphate'通常作为不可数物质名词,应使用'phosphate fertilizer'等具体搭配以避免歧义。

❌ 错误:This water has high phosphate.
✓ 正确:This water has a high phosphate level.

错误用法中直接使用'high phosphate',但'phosphate'作为名词时,常与'level'、'content'等词搭配表示程度,正确用法应为'a high phosphate level'以更准确表达含义。
