Digital Medicine
Could the next suggestion from your doctor be downloading an app? Collectively known as digital medicine, a large number of apps in use or under development can now detect or monitor mental and physical disorders or directly administer therapies. 1. ____D____
Many detection aids rely on mobile devices to record such features as users’ voices, locations, facial expressions, exercise and sleep; then they apply artificial intelligence to mark the possible change of a condition. Some smart watches, for instance, contain a sensor that automatically detects and warns people of a dangerous heart rate. 2. ____C____ These wearable detection aids will not replace a doctor any time soon but can be helpful partners in stressing concerns that need follow-up. 3. ____E____ Some are being developed to detect things such as cancerous DNA, stomach bleeds, body temperature and oxygen levels. The sensors inside your body can then send the data to apps for recording.
4. ____G____ For the most part, those intended to diagnose or treat disorders must be proved safe and effective in clinical trials and earn regulatory approval; some may need a doctor’s permission.
Clearly, society must move into the future of digital medicine with care—ensuring that the apps go through strict testing, protect privacy and go smoothly into doctors’ work. With such protections in place, healthcare costs could be saved by marking unhealthy behaviours and helping people to make changes before diseases set in. 5. ____A____ For researchers, the patterns that emerge will provide them with novel ideas for how best to build healthier habits and prevent diseases.

答案： 1. D 该段内容介绍数字医疗具备的功能，D 项承接前文，继续介绍数字医疗的功能，其中的“They”指代前文的“a large number of apps”。故选 D。
2. C 前文“Some smart watches... warns people of a dangerous heart rate.”列举智能手表中的检测提醒功能，后文“These wearable detection aids... follow-up.”对可穿戴检测辅助设备的作用进行评估，C 项承前启后，后文的“These wearable detection aids”涵盖前文的“Some smart watches”和选项中的“Other similar tools”。故选 C。
3. E 前文“These wearable detection aids... follow-up.”对可穿戴检测辅助设备的作用进行评估，后文“Some are being developed to detect things... send the data to apps for recording.”介绍新的置于体内的检测辅助设备，E 项符合语境，说明检测辅助设备的新形式，从前文的可穿戴的形式过渡到后文的介入人体内的新形式，其中的“eatable and sensor-bearing”和后文的“The sensors inside your body”呼应。故选 E。
4. G 空处位于段首，需引出段落内容。该段内容指出数字医疗发展中的严格限制和流程，G 项符合语境，说明数字医疗有其限制，可引出后文。故选 G。
