Language Output Ability 语言输出能力

Oral: 口语：

Clear articulation, able to express technical ideas, though sometimes hesitant when needing to elaborate for maximum marks. 表达清晰，能够阐述技术观点，但在需要详细阐述以获得最高分数时有时会犹豫。

Written: 书面：

Not directly graded on paper, but answers provided verbally showed good content but often lacked the specific depth/keywords required for full marks.
