本文为 KS3 CIE 骨骼填空工作表提供详细评分标准。它解释了预期答案、分值分配以及教师在评分时应接受的常见等价答案，适用于剑桥初中科学与 Checkpoint 备考。
1. What the Skeleton Gapped Worksheet Assesses | 骨骼填空工作表评估内容
The worksheet typically assesses three areas: the functions of the human skeleton, the names and positions of major bones, and the structure of joints. Each gap is worth one mark unless a question states otherwise. The total mark is usually 20 to 25.
填空工作表通常评估三个领域：人体骨骼的功能、主要骨骼的名称和位置以及关节的结构。每个空值 1 分，除非题目另有说明。总分通常为 20 至 25 分。
If a question contains two blanks, such as "The ribcage protects the ____ and ____" receives one mark. Marks are independent, so an error in one gap does not affect another.
如果一道题包含两个空，例如“肋骨保护 ____ 和 ____”，每个可接受答案各得 1 分。各空独立评分，一个空错误不影响另一个空。
2. General Marking Principles | 总体评分原则
In CIE KS3 science, spelling of technical terms is usually not penalised if the word is phonetically recognisable. However, if the misspelling changes the meaning, the mark should not be awarded. For example, "femur" written as "femer" can be accepted, but "humerus" written as "humorous" should be rejected because it is a different word.
在 CIE KS3 科学中，技术术语的拼写通常不扣分，只要拼写能辨认发音即可。但如果拼写错误改变了含义，则不应给分。例如，“femur”写成“femer”可以接受，但“humerus”写成“humorous”应判错，因为它是另一个词。
Common names may be accepted for some bones, but the mark scheme below also shows the precise anatomical term. Teachers should use professional judgment when a learner gives an acceptable everyday name, such as "skull bone" for "cranium".
某些骨骼可使用通用名称，但下方评分标准也给出了精确的解剖学术语。当学生给出可接受的日常名称时，如用“skull bone”表示“cranium”，教师应使用专业判断给分。
3. Section A: Functions of the Skeleton | A 部分：骨骼的功能
The first section of the gapped worksheet asks learners to complete a function list. The most common gapped sentence is: "The human skeleton has five main functions:
