第一題：中翻英【20 分】 肥胖是已開發國家中一個廣泛的問題，有一成的人口過重或肥胖，高達半數的人口稍微過重。因此，胖小孩很可能長大變成胖大人，年長後還增加心臟病的風險，就不足為怪了。 最好在年輕時避免這個問題，而且在變成問題以前先消除過多的體重。

第二題：中翻英【20 分】 台灣逐漸邁入 M 型社會，新貧家庭不斷增加。據統計台灣有超過 37 萬名弱勢兒童，其中 15 萬多人過著貧窮與高風險的生活。由於父母沒有能力供他們參加校外課輔班，放學後 也無人陪伴教導，導致許多孩子放棄學習，在外遊蕩，流連不良場所，成為社會隱憂。

第三題：英翻中【20 分】          In a survey of 4,000 remote workers, an employment website found that 95 percent of respondents report their productivity is the same as or higher than it was before the pandemic. In the survey, workers offered several reasons for their positive news on productivity. Among them were fewer interruptions, quieter environment, more comfortable workplace, more focused time and avoiding office politics.          Despite the highly positive responses, the remote workers find themselves dealing with a new dilemma: how to keep work life and home life separate when both happen in the same place. Telecommuting experts offer a tip on creating spaces and routines to help you maintain professionalism and productivity in your new “office” and keep work from creeping into personal and family time. You can establish a place that is just for work—a place where you can be in office mode, and where others in the house know not to disturb you unless necessary.

第四題：英翻中【20 分】           The merging of machine capability and human consciousness is already happening in the form of bionic technology.

Currently available devices are mostly apparatus that can replace damaged sensory organs. Cochlear implants can recover hearing for the deaf while retinal implants can help the blind see again. Bionic technology will even be offering more elective augmentation for able-bodied people, a trend that may soon become global in the next decade.
