在台灣有許多人渴望考取公務人員，投入公務員考試的人數一直居高不下，雖然有許多以語料庫當作工具的研究，卻很少研究主題在關注在公務人員的考試上，因此本研究目的在於分析從2007到2013年之間，公務人員考試的英文試題，研究出現在試題當中的高頻率單字，以及字彙的涵蓋率。並以Wordsmith為工具，製作出字彙表和找出高頻率單字，再以Range作分析的工具，統計出單字的字彙量，進而和BNC作比較。本研究主要建立了兩個語料庫，第一個是高普考，另一個是地方特考，從這兩個主要的語料庫，可以得出8個字彙表，以及互相重複的字彙，最後再和BNC做比較時就可以得知他們的字彙量。研究結果顯示出高普考和地方特考的字彙覆蓋率為77%。從結果可以得知公務人員考試的等級是依據難度而向上提升的。

Civil service examinations have been attracting more and more attention due to the increasing number of test-takers in Taiwan. As there are many corpus-based studies on textbooks and academic fields, few studies have focus on civil service examinations. This study aims to examine the most frequently used words in civil service examinations (2007-2013) in Taiwan and the vocabulary coverage. Wordsmith was implemented to create wordlists and to explore the most frequently used words. The analytical tool, Range was used to make comparisons of the vocabulary coverage with BNC. In order to make comparisons, two major corpora were constructed, including (1) Civil Service Level 3 (高普考), (2) Civil Service Special Examination of 3 levels (地方特考). The results firstly provide 8 different wordlists based on frequency, the overlapping rate and words between the two main corpora and the vocabulary coverage between civil service examinations compared with BNC. Results show that the overlapping rates between Civil Service Level 3 and Civil Service Special Examination of 3 Levels word lists are 55.7%. Lastly, the vocabulary coverage of Civil Service Examinations are presented and compared. It's found that the levels of each civil service examinations are consistent accordance with the designed level by the Ministry of Examinations.
