📚 Interdisciplinary Question Training for SQA Computing | SQA 计算机跨学科综合题型训练
Interdisciplinary questions are increasingly common in SQA Computing assessments. They combine computational thinking with concepts from mathematics, science, geography, arts, and social subjects. This article provides targeted question training to help you apply programming, databases, web design, and data representation skills across different contexts.
跨学科综合题型在 SQA 计算机测试中越来越常见。它们将计算思维与数学、科学、地理、艺术和社会学科的概念结合起来。本文提供针对性题型训练，帮助你在不同情境中应用编程、数据库、网页设计和数据表示等技能。
1. Mathematics & Algorithms: Quadratic Equation Solver | 数学与算法：一元二次方程求解器
, and outputs the real roots. This combines algebraic discriminant analysis with conditional logic in programming.
题目：设计一个算法，要求用户输入一元二次方程 ax²+bx+c=0 的系数 a、b 和 c，并输出实数根。这结合了代数判别式分析与编程中的条件逻辑。
roots. If d = 0, there is one real root: x = −b/(2a). If d > 0, two real roots: x = (−b ± √d)/(2a). Use selection (if-else) statements.
解题思路：计算判别式 d = b² − 4ac。如果 d < 0，没有实数根。如果 d = 0，有一个实数根：x = −b/(2a)。如果 d > 0，有两个实数根：x = (−b ± √d)/(2a)。使用选择（if-else）语句。
Pseudocode:
伪代码：
INPUT a, b, c
d ← b² − 4ac
IF d < 0 THEN
OUTPUT "No real roots"
ELSE IF d = 0 THEN
x ← −b/(2a)
OUTPUT "One root: ", x
ELSE
x1 ← (−b + √d)/(2a)
x2 ← (−b − √d)/(2a)
OUTPUT "Two roots: ", x1, x2
ENDIF
logic efficiently. Edge cases such as a=0 (linear equation) could be added for robustness.
关键跨学科联系：数学提供了公式，而计算高效地实现了逻辑。可以增加边界情况，如 a=0（线性方程），以提高鲁棒性。
2. Physics & Data Logging: Temperature Conversion Logger | 物理与数据记录：温度转换记录器
input values in Celsius and produce a table with both units. Use the formula F = (C × 9/5) + 32.
题目：一个科学实验需要每分钟记录温度读数，将摄氏度转换为华氏度。编写一个程序，存储 10 个摄氏温度输入值，并生成包含两个单位的表格。使用公式 F = (C × 9/5) + 32。
This task integrates physics units, arrays (or lists) in programming, and output formatting. Data logging is essential in scientific experiments where computers automate calculations.
该任务融合了物理单位、编程中的数组（或列表）以及输出格式化。在科学实验中，数据记录是必不可少的，计算机可以自动完成计算。
Solution: Use a loop to read 10 Celsius values into an array. Then for each value, compute Fahrenheit and print side by side. Ensure array index is correctly managed. Example output table:
解决方案：使用循环将 10 个摄氏值读入数组。然后对每个值计算华氏度并并排输出。确保正确管理数组索引。示例输出表格：
| Celsius | Fahrenheit |
| 0 | 32.0 |
| 20 | 68.0 |
Interdisciplinary skill: Understanding unit conversion and automation mirrors real-world sensor systems.
跨学科技能：理解单位换算与自动化，反映了现实世界传感器系统的工作方式。
3. Biology & Binary Coding: DNA Sequence Compression | 生物与二进制编码：DNA 序列压缩
Problem: DNA is made of four bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). Design a binary encoding where each base is represented by 2 bits. Encode the sequence "ATCGGA" and calculate the number of bytes required before and after compression, assuming original ASCII uses 1 byte per character.
题目：DNA 由四种碱基组成：腺嘌呤（A）、胸腺嘧啶（T）、胞嘧啶（C）和鸟嘌呤（G）。设计一种二进制编码，每个碱基用 2 位表示。对序列 "ATCGGA" 进行编码，并计算压缩前后所需的字节数，假设原始 ASCII 每个字符占用 1 个字节。
Encoding table:
| Base | Binary Code |
| A | 00 |
| T | 01 |
| C | 10 |
| G | 11 |
The binary representation of "ATCGGA" n be stored in 2 bytes with padding. This demonstrates how biological data storage can be optimised using binary encoding, a key concept in bioinformatics.
"ATCGGA" 的二进制表示为 00 01 10 11 11 00。连接后：000110111100₂。原 6 个字符需 6 字节。压缩后：6 × 2 位 = 12 位 = 1.5 字节，补齐后可存入 2 字节。这展示了如何使用二进制编码优化生物数据存储，这是生物信息学的关键概念。
4. Geography & Database: Querying World Cities | 地理与数据库：查询世界城市
Problem: A database table 'Cities' has fields: Name, Country, Population, Area. Write a query
