9. Governments enforce strict ___ in GMO approvals, requiring extensive toxicity and allergenicity(致敏性) testing to prevent contamination and unforeseen health consequences. (caution)
题目解答
答案
根据题目要求,需将“caution”填入空格。分析可知,“strict”后需接名词“caution”,表示“谨慎”。尽管“precautions”更贴合语义,但不符合题目限制。最终,填入“caution”即可。完整句子为:
"Governments enforce strict caution in GMO approvals, requiring extensive toxicity and allergenicity testing to prevent contamination and unforeseen health consequences."
答案:caution
解析
本题考查词汇的词性运用。解题思路如下:
- 首先,分析句子结构。在“Governments enforce strict ___ in GMO approvals”这个句子中,“strict”是形容词,通常用来修饰名词。所以,空格处需要填入一个名词。
- 接着,看所给单词“caution”,它本身既可以作动词,也可以作名词,作名词时意为“谨慎;小心”。
- 虽然从语义上来说,“precautions”(预防措施)可能更符合语境,但题目明确要求使用“caution”这个词,所以我们只能将“caution”填入空格。
- 最后,将“caution”代入句子中,“Governments enforce strict caution in GMO approvals, requiring extensive toxicity and allergenicity testing to prevent contamination and unforeseen health consequences.” 句子表达“政府在转基因生物审批中执行严格的谨慎措施,要求进行广泛的毒性和致敏性测试,以防止污染和不可预见的健康后果”,语义通顺合理。
