欢迎阅读你的 Year 10 WJEC 生物升学衔接指南。本资源旨在帮助你巩固本学年的关键概念，培养核心技能，并为 Year 11 及以后的挑战做好准备。无论你的目标是 GCSE 高分还是考虑学习 A-Level 生物，Year 10 的扎实基础都至关重要。
1. Understanding the WJEC Year 10 Biology Curriculum | 了解 WJEC Year 10 生物学课程
The WJEC GCSE Biology specification builds your understanding of living organisms progressively. In Year 10, you typically cover foundational units such as Cells, Organ Systems and Ecosystems (Unit 1) and begin topics from Variation, Homeostasis and Micro-organisms (Unit 2). You explore the building blocks of life, how organisms function, and their interactions with the environment. This knowledge sets the stage for more complex ideas in Year 11.
WJEC GCSE 生物课程逐步建立你对生命体的理解。在 Year 10，你通常会学习细胞、器官系统和生态系统（单元1）等基础单元，并开始接触变异、体内平衡和微生物（单元2）等主题。你将探索生命的基石、有机体的运作方式及其与环境的相互作用。这些知识为 Year 11 的更复杂概念奠定基础。
Grasping the structure of the curriculum helps you see the big picture. Each topic is connected; for example, understanding cell transport is essential for digestion and plant nutrition. Use the specification as a checklist to track your progress and identify areas that need more attention.
掌握课程结构有助于你把握全局。每个主题都是相互关联的；例如，理解细胞运输对消化和植物营养至关重要。将考试大纲用作核对清单，追踪你的学习进度并找出需要更多关注的领域。
2. Core Topic: Cells and Organisation | 核心主题：细胞与组织
You learned that all living things are made of cells. Eukaryotic cells (plants and animals) contain membrane-bound organelles such as a nucleus, mitochondria, ribosomes, and in plant cells, chloroplasts and a permanent vacuole. Prokaryotic cells (bacteria) are smaller, with no nucleus, but they have a cell wall and a single loop of DNA.
你学到了所有生物都由细胞组成。真核细胞（植物和动物）含有膜结合的细胞器，如细胞核、线粒体、核糖体，在植物细胞中还包含叶绿体和永久液泡。原核细胞（细菌）较小，没有细胞核，但有细胞壁和单链 DNA 环。
emember to convert units carefully, for example 1 mm = 1000 μm. Be familiar with the steps for preparing a specimen on a slide, from staining to focusing.
显微镜技能至关重要。你必须能使用公式计算放大倍数：放大倍数 = 图像大小 / 物体实际大小。记住单位换算要仔细，例如 1 mm = 1000 μm。熟悉从染色到调焦制作玻片标本的步骤。
Cell differentiation and stem cells are key. Stem cells are undifferentiated cells that can become specialised cells. You discussed ethical issues surrounding embryonic and adult stem cells, as well as their potential in treating conditions like diabetes and spinal injuries.
细胞分化和干细胞是关键。干细胞是未分化的细胞，可成为特化细胞。你讨论了胚胎干细胞和成体干细胞相关的伦理问题，以及它们在治疗糖尿病和脊髓损伤等疾病中的潜力。
3. Core Topic: Transport Systems | 核心主题：运输系统
Substances move across cell membranes by diffusion, osmosis (a special case of diffusion for water across a partially permeable membrane), and active transport (which requires energy). You need to recall definitions and explain how these processes are adapted for efficient exchange in lungs, gills, roots, and the small intestine.
物质通过扩散、渗透（水跨越部分透膜的扩散特例）和主动运输（需要能量）穿过细胞膜。你需要牢记定义，并能解释这些过程如何适应肺、鳃、根和小肠中的高效交换。
The human circulatory system comprises the heart (a double pump), blood vessels (arteries, veins, capillaries), and blood. You should be able to label the heart's chambers, explain how valves prevent backflow, and describe the functions of red blood cells, white blood cells, platelets and plasma.
人体循环系统包括心脏（双泵）、血管（动脉、静脉、毛细血管）和血液。你应该能标记心脏的腔室，解释瓣膜如何防止倒流，并描述红细胞、白细胞、血小板和血浆的功能。
In plants, xylem transports water and minerals upwards, supported by the cohesion-tension theory. Phloem transports sucrose and amino acids through translocation. You also covered factors affecting transpiration rate, such as temperature, humidity, light intensity and wind.
在植物中，木质部通过内聚力-张力理论向上运输水和矿物质。韧皮部通过转运运输蔗糖和氨基酸。你还学习了影响蒸腾速率的因素，如温度、湿度、光照强度和风。
4. Core Topic: Health, Disease and the Development of Medicine | 核心主题：健康、疾病与医学发展
Communicable diseases are caused by pathogens: viruses (e.g., measles, HIV), bacteria (e.g., Salmonella, tuberculosis), fungi (e.g., athlete's foot) and protists (e.g., malaria). You need to know their modes of transmission and methods of control, such as vaccination, hygiene and vector control.
传染病由病原体引起：病毒（如麻疹、HIV）、细菌（如沙门氏菌、结核病）、真菌（如脚癣）和原生生物（如疟疾）。你需要了解它们的传播途径和控制方法，如疫苗接种、卫生和病媒控制。
The human body defends itself with non-specific barriers (skin, stomach acid) and the specific immune system. White blood cells produce antibodies, engulf pathogens, and produce antitoxins. Vaccination triggers the production of memory cells, providing long-term immunity.
人体通过非特异性屏障（皮肤、胃酸）和特异性免疫系统进行防御。白细胞产生抗体、吞噬病原体并产生抗毒素。疫苗接种触发记忆细胞的
