用法要点

句型搭配

通常用作可数名词,在句子中作主语或宾语,描述其作用或特性。

• The mutagen caused DNA damage.
• Exposure to mutagens can lead to cancer.
• Scientists study various mutagens in labs.

介词用法

常与介词如 'to'(暴露于)、'from'(来源)、'in'(在...中)搭配,表示关系或环境。

• Exposure to mutagens is hazardous.
• Protection from mutagens is essential.
• Mutagens in the environment pose risks.

语域说明

主要用于学术、科学和医学语境,在正式讨论或专业写作中出现,日常对话中较少使用。

• In genetic research, mutagens are key tools.
• The report highlighted mutagen risks.
• Avoid mutagens in industrial settings.

基础例句

Some chemicals in cigarettes are known mutagens that can harm your health.

香烟中的某些化学物质是已知的诱变剂,可能危害健康。

In science class, we learned about mutagens and how they affect DNA.

在科学课上,我们学习了诱变剂及其如何影响DNA。

To stay safe, avoid exposure to environmental mutagens like radiation.

为了安全,要避免接触辐射等环境诱变剂。

The doctor warned that certain drugs might act as mutagens if misused.

医生警告说,某些药物如果滥用可能起到诱变剂的作用。

高级例句

The study identified a new mutagen in industrial waste, prompting stricter regulations.

该研究在工业废物中发现了一种新的诱变剂,促使了更严格的法规出台。

In genetic engineering, controlled use of mutagens can help develop crop varieties with enhanced traits.

在基因工程中,受控使用诱变剂有助于开发具有增强性状的作物品种。

The pharmaceutical company conducted mutagenicity tests to ensure drug safety before clinical trials.

制药公司在临床试验前进行了致突变性测试,以确保药物安全。

常见错误

❌ 错误:The mutagen is a kind of medicine.
✓ 正确:The mutagen is a type of agent that can cause mutations.

错误:将诱变剂误认为是药物;正确:诱变剂是一种能引起突变的物质,不一定是药物,可能是有害的化学或物理因素。

❌ 错误:I feel mutagen when I touch it.
✓ 正确:I might be exposed to mutagens if I touch certain chemicals.

错误:用'feel'描述接触诱变剂,不准确;正确:使用'exposed to'表示暴露于诱变剂,更符合科学表达。

近义词辨析

carcinogen

致癌物特指能引起癌症的物质,而诱变剂是能引起基因突变的物质,不一定致癌;所有致癌物可能是诱变剂,但并非所有诱变剂都是致癌物。

Some mutagens are also carcinogens, but not all mutagens lead to cancer.

teratogen

致畸物是能导致胎儿发育畸形的物质,而诱变剂是引起基因突变的物质;致畸物可能通过突变起作用,但焦点不同,一个在发育,一个在基因变化。

A teratogen affects fetal development, whereas a mutagen causes genetic changes that might not be immediately visible.
