2024年6月英语六级第3套真题句子解析： It isn't ground-breaking to say workers feel fatigued after a meeting, but only in recent decades have scientists deemed the condition worthy of further investigation.

It isn't ground-breaking to say workers feel fatigued after a meeting

句首的"It"是形式主语,不指代任何实际内容,真正的主语是后面的不定式短语"to say workers feel fatigued after a meeting"(说工人会后感到疲劳)。句子的基本结构是"It is + 形容词 + to do",其中"It"占据主语位置,避免头重脚轻,将真正的主语不定式后置。完整的逻辑意思是"To say workers feel fatigued after a meeting isn't ground-breaking"(说工人会后感到疲劳并非突破性发现)。

It isn't ground-breaking to say workers feel fatigued after a meeting, but only in recent decades have scientists deemed the condition worthy of further investigation

句子由"but"连接两个独立的主谓结构,构成并列句。前一分句的主干是"It isn't ground-breaking"(这并非突破性的),后一分句的主干是"scientists have deemed the condition worthy"(科学家认为这种状况值得研究)。"but"表示转折关系:虽然工人会后疲劳是常识(不新鲜),但科学家直到最近才认为值得深入研究。两个分句地位对等,通过对等连词"but"连接,符合并列句的定义。

only in recent decades have scientists deemed the condition worthy of further investigation

当"only + 状语"位于句首时,句子需要部分倒装,即将助动词提到主语之前。此处"only in recent decades"(仅在最近几十年)作时间状语前置到句首,触发了部分倒装,将助动词"have"提前到主语"scientists"之前,构成"have scientists deemed"的倒装语序。正常语序应为"scientists have only deemed the condition worthy of further investigation in recent decades"。这是典型的"only + 状语"前置引发的部分倒装结构。

deemed the condition worthy of further investigation

本句中 "worthy of" 是固定搭配,表示「值得…的」。结构为 "deem + 宾语 + worthy of + 名词",其中 worthy of 构成宾语补足语。

"worthy of" 的核心语义是「配得上/值得」,后接名词表示所值得的对象或行为。常见搭配有 be worthy of attention/consideration/praise/investigation 等。

该搭配的关键学习点:

1. worthy 后必须跟 of,不能省略(区别于 worth 可直接接名词:worth doing);

2. of 后接名词或动名词,表示值得的内容;

3. 可用于 "consider/deem/think/find + 宾语 + worthy of" 结构中作宾补。

本句 "deemed the condition worthy of further investigation" 意为「认为这种状况值得进一步研究」,worthy of 作宾语补足语,修饰 the condition。
