前言

第一屆香港中學文憑考試的成績已於本年 7 月 20 日發布。為讓教師、學生以及公人士進一步了解中學文憑考試考生的水平，本局選取個別考生的答卷，

輯錄為本套示例，以助說明各級考生的表現。

本科設有三卷，本套示例取材於其中的傳統筆試答卷，以便於說明各等級考生的

典型表現。卷一甲部為多項選擇題、卷三為校本評核，由於考生多項選擇題的答

案難以說明不同等級的表現及考生的校本評核課業樣本只屬有關評核的一部

分，因此未有選用這些卷別作為示例。

參閱這套示例時，讀者亦宜同時參考本年試卷及評卷參考，以了解試題及評分要

求。有關文件會刊於本年 10 月至 11 月間出版的《 2012 年香港中學文憑考試 --考試報告及試題專輯》內。

INTRODUCTION

The results of the first HKDSE Examination were released on 20 July 2012. To enhance the understanding of the standards of the HKDSE Examination, authentic samples of candidates’ scripts are selected to form this set of exemplars to illustrate the performance standards at different levels.

There are 3 papers in this subject. This set of exemplars is selected from candidates’ scripts of the written conventional papers to illustrate the typical performance standards at different levels. Paper 1 Section A comprises Multiple-choice (MC) questions while Paper 3 is the School-based Assessment. As candidates’ MC responses cannot illustrate well the performance standards and their SBA work only represents part of the assessment, exemplars have not been selected from these papers.

It is advisable to read this set of exemplars together with the question papers and the marking schemes in order to understand the requirements of the questions and the marking criteria. The question papers and the marking schemes will be published in the Examination Report and Question Papers for 2012 HKDSE which will be available for sale in October / November this year.
