〔内容深度拆解〕材料专业考研英语一与英语二的考试内容全解析
英语一:全面能力导向的学术型考试
英语一内容覆盖全面,对语言综合能力要求高,特别适合具备扎实语言基础、计划攻读学硕并进入科研院所深造的材料专业考生。
- 完形填空(10分):20空,一篇约250词短文,考察词汇辨析、固定搭配、逻辑连贯性。例如2023年真题出现“nanomaterials”“self-assembly”等材料专业相关术语语境选择。
- 阅读理解(40分):四篇独立短文,每篇400词左右,含细节题、推理题、主旨题、词义题。题材广泛,如2022年阅读Text 3探讨“graphene-based composites for aerospace applications”;2021年Text 4聚焦“recyclable thermosets in circular economy”。
- 新题型(10分):从七选五、排序、小标题匹配三类中任选其一。七选五最常见,如2023年考题为关于“additive manufacturing challenges”的段落逻辑衔接。
- 翻译(英译汉)(15分):150词左右科技类段落,常含长难句、被动语态、非谓语结构。如2022年真题:“The development of high-entropy alloys has revolutionized traditional alloy design paradigms by incorporating multiple principal elements in near-equal ratios.”
- 写作(25分):小作文(书信/通知/摘要)+大作文(议论文)。大作文常围绕科技伦理、创新政策、可持续发展展开。2023年大作文题为“Discuss the balance between scientific advancement and ethical responsibility in materials research.”
典型例题节选(2023年英语一真题)
【阅读理解】Text 1 Passage 2节选:
“Metal-organic frameworks (MOFs) represent a class of porous materials with exceptional surface areas and tunable functionalities. Their application in hydrogen storage for fuel-cell vehicles has drawn considerable attention, yet challenges remain in achieving practical storage capacities under ambient conditions.”
→ 问题:What is the primary challenge mentioned in the passage regarding MOFs for hydrogen storage?(细节推断)
英语二:聚焦学术应用的实践型考试
英语二内容更精炼,强调材料专业实际应用中的阅读与写作能力,适合以工程实践为导向、计划进入企业或科研院所应用型岗位的考生。
- 阅读理解(40分):一篇长文(约1500词)+5道选择题;或两篇短文(各300–400词)+5题。2023年真题长文题为“The Role of Surface Functionalization in Enhancing Nanoparticle Dispersion in Polymer Matrices”,考察段落主旨、作者态度、信息匹配。
- 完形填空(0分):不设此题型,减轻考生负担。
- 新题型(10分):多为“七选五”简化版或“信息匹配”,如给出5个段落标题与5个段落,要求匹配。2022年考题为“Matching headings to paragraphs about polymer recycling technologies”。
- 翻译(英译汉)(15分):150词左右段落,多为科技文献节选,句子结构相对简单。2023年真题:“3D printing of ceramic components requires precise control of slurry rheology and drying stress to prevent cracking during post-processing.”
- 写作(25分):小作文(通知/报告/建议信)+图表作文(描述+分析)。2023年图表作文题为“Describe the trend of global R&D investment in advanced ceramics from 2018 to 2022 and suggest reasons for the change.”
典型例题节选(2023年英语二真题)
【阅读理解】Passage节选:
“The adoption of AI-driven predictive models in materials discovery has accelerated the identification of candidates for solid-state batteries. However, model interpretability remains a critical bottleneck in gaining trust from experimentalists.”
→ 问题:According to the passage, what is the main limitation of AI models in materials research?(细节理解)
