燃油样品检查发现有微生物污染。
答案解析
解析：
**A: Fuel sample was checked for contamination of microorganism.**
- 这个句子使用了被动语态，表达了“燃油样品被检查以检测微生物污染”。虽然语法上没有错误，但它并没有明确说明检查的结果是什么。我们不知道样品是否被污染了。
**B: Contamination to microorganism was detected in the fuel sample.**
- 这个句子在语法上存在问题。“Contamination to microorganism”这个短语不太通顺，应该是“contamination by microorganism”或“contamination of microorganism”。此外，这个句子也没有明确说明污染的性质。
**C: Fuel sample check reveals positive contamination of microorganism growth.**
- 这个句子清晰地表达了检查的结果，使用了“reveals positive contamination”，说明检查结果是阳性，确实发现了微生物的污染。这个句子结构合理，信息完整，是最准确的表述。
### 知识点解析
在科学和技术领域，准确的语言表达至关重要。特别是在描述实验结果时，使用明确的术语和结构可以避免误解。例如，在实验室报告中，通常会使用“检测到”或“发现”这样的词汇来清晰地传达结果。
### 生动的例子
想象一下你在一个科学实验室工作，正在检查水样是否受到细菌污染。你可能会写下这样的报告：
- “水样检查显示细菌污染阳性。”（类似于选项C）
如果你写成：
- “水样被检查以检测细菌污染。”（类似于选项A）
那么，读者就无法得知水样的实际情况。
