核心语法结构 — 英语阅读题

Last semester, Professor Chen introduced a new method for analyzing academic papers. He emphasized that students should focus on the logical structure rather than just memorizing vocabulary. 'The key to effective writing,' he stated, 'lies in understanding how non-finite verbs function as modifiers or complements.' Many students initially struggled with this concept, particularly when distinguishing between present and past participles. However, after two weeks of intensive practice involving rewriting complex sentences, their accuracy improved significantly. The final assessment revealed that those who mastered the logical subject relationship of non-finite verbs scored 20% higher on grammar sections. This experience highlighted the importance of applying theoretical knowledge to practical writing tasks, ensuring that students could produce clear and coherent academic texts. Based on the passage, what was the primary reason for the improved scores in the final assessment? A) Students memorized a larger number of high-frequency vocabulary words. B) Students mastered the logical subject relationship of non-finite verbs. C) Professor Chen reduced the difficulty of the exam questions. D) Students spent more time reading academic papers.
