📚 KS3 CIE Skeleton Gapped Worksheet: Bones, Joints and Movement | KS3 CIE 骨骼填空练习：骨、关节与运动
This gapped worksheet is designed for KS3 CIE Biology students revising the human skeleton, joints and movement. It can be printed or completed on screen. Each gap should be filled with one word or a short phrase, taken either from the word bank in Section 2 or from your own knowledge. Work through Sections 1 to 11 in order, and use the answer key in Section 11 to mark your work, find misconceptions and plan your revision.
这套填空练习专为 KS3 CIE 生物课程中复习人体骨骼、关节和运动的学生设计，可打印或在屏幕上完成。每个空格应填入一个单词或短语，答案可以取自第 2 节的词库，也可以来自你自己的知识。请按顺序完成第 1 至第 11 节，并用第 11 节的答案要点批改自己的练习，找出误解并安排复习。
1. Learning Goals | 学习目标
By the end of this gapped worksheet, you should be able to name the main bones of the human skeleton, describe four functions of the skeleton, explain the difference between hinge and ball-and-socket joints, and use the key terms cartilage, ligament, tendon, synovial fluid and bone marrow correctly. You should also be able to explain how a pair of antagonistic muscles moves a bone about a joint.
完成这套填空练习后，你应该能说出人体骨骼的主要骨名，描述骨骼的四个功能，解释铰链关节与球窝关节的区别，并正确使用软骨、韧带、肌腱、滑液和骨髓等关键术语。你还应能解释一对拮抗肌如何使骨绕关节运动。
This worksheet follows the KS3 CIE Biology topic on the skeleton and movement. In a typical revision test each gap is worth one mark, and the spelling of scientific terms must be accurate. Read the whole sentence carefully before you write an answer, because the surrounding words usually tell you what kind of word is missing.
本练习对应 KS3 CIE 生物中骨骼与运动主题。在典型的复习测试中，每空一分，且科学术语的拼写必须准确。写答案前请通读整句，因为句子中前后的词通常能提示所缺词的类型。
- Name the main bones of the human skeleton and locate them on a diagram.
说出人体骨骼的主要骨名，并能在图上指出它们的位置。 - Describe the four functions of the skeleton: support, protection, movement and the production of blood cells.
描述骨骼的四个功能：支持、保护、运动和造血。 - Explain the difference between a hinge joint and a ball-and-socket joint, giving examples of each.
举例解释铰链关节与球窝关节的区别。 - Use the terms cartilage, ligament, tendon, synovial fluid and bone marrow correctly.
正确使用软骨、韧带、肌腱、滑液和骨髓等术语。 - Explain how antagonistic muscles work in pairs to produce movement.
解释拮抗肌如何成对工作以产生运动。
2. Word Bank for the Gaps | 填空词库
Here is the word bank. Not every word is used only once, and some words may fit more than one gap, so pay close attention to the context of each sentence. A few gaps are deliberately not covered by the word bank: for those you must use your own knowledge and the correct scientific term.
以下是词库。并非每个单词只使用一次，有些词可能适合多个空格，因此请特别注意每个句子的语境。有少数空格故意不在词库范围内：这些空需要你运用自己的知识和正确的科学术语来填写。
