Around the world, Traditional Chinese Medicine (TCM) is     1     hot topic. It seems that most health food stores have a section with TCM herbal remedies, and many cities have at least one acupuncture (针灸) clinic. What’s more, some Western doctors recommend TCM for certain illnesses. Within China, TCM is     2     (wide) used. All in all, 28% of drug sales in China are made up     3     medicinal herbs, and there are over 4,000 TCM hospitals in China. Let     4     (we) take a look at how TCM started.

In ancient times, many people around the world thought that illnesses     5     (cause) by evil spirits, and so spells and prayers were used to get rid of the spirits and thus bring relief. At the same time, some doctors in China recognized that many illnesses had     6     (vary) possible natural causes. The doctors believed that since illnesses were natural in origin, they could be cured through natural remedies. Perhaps the most important of these early doctors was Qin Yueren, who wandered from place to place,     7     (provide) medical care to those in need. He was so respected     8     people called him Bian Que.

Much of what has been passed down through history about Bian Que has a legendary quality. However, Bian Que sought     9     (set) the medical profession on a firm basis of preventative treatment, observing symptoms, and offering natural     10     (cure) without resorting to spells.

2 . The 21st-century doctor now carries a whole set of diagnostic tools in his briefcase, and yes, unfortunately, the iconic stethoscope (听诊器) is now a little outdated! So, exactly what are all these necessary devices for the 21st century doctor?

The stethoscope goes digital. The Eko Core is the new revolution of stethoscopes. It can amplify the sounds of the heart by 40 times when in digital mode. It can also stream the heartbeat data to the cloud, allowing the physician to see the heartbeat in wave form on a mobile device as well as hear the sound at an amplified level.

A palm-sized ECG device. If someone asks you to think about the electrocardiogram (心电图) device, you will probably imagine a huge machine with many wires that are connected to a screen giving someone’s heart activity. In today’s digital health era, this machine has been down-sized so it can fit in the palm of your hand. The KardiaMobile 6L is a 6-lead medical-grade pocket-sized ECG machine. It will send the readings directly to your smartphone.

High-tech eye tech. The Personal Vision Tracker and the EyeQue Insight are light, accurate, and inexpensive devices. They allow for eye tests to be performed remotely.

Ear tech in your pocket. Ear examination can be uncomfortable for the patient and challenging for physicians in case of small or partially obstructed ear canals. The pocketable WiscMed otoscope aims to overcome these issues with its built-in nano camera which gives clear images of the eardrum.

TCM is short for Traditional Chinese Medicine. TCM, which has a history of more than 2,500 years in China,     1     (play) a big role in treating patients infected with COVID-19 so far. Let’s look at     2     it works. TCM cannot kill the virus,     3     it can treat patients by removing the trash which causes illness out of human body.     4     the trash, the virus will have no room to survive.

In early February, 102 mild patients in Wuhan received therapy with Jinhua Qinggan Granule (颗粒). As     5     result, it took only one and a half days for most patients taking it    6     (reduce) fever. An experiment of 710 cases     7     (conduct) by over 30 hospitals showed the Xuebijing Injection (注射剂), combined with regular     8     (treat), can reduce the mortality rate of severe patients by 8.8 percent.    9     (basic), TCM is believed to be more effective for disease prevention, while western medicine is     10     (good) for serious illnesses.

The 1918 Spanish flu was the most deadly outbreak in history. It     1     (cause) by an H1N1 virus found in genes of birds' origin. Although there is no universal agreement regarding where the virus     2     (actual) originated, it spread worldwide during 1918-1919. In the United States, it was first identified in the army in     3     spring of 1918.

It was estimated that about 500 million people     4     one-third of the world's population of that time became infected with this virus. The number of     5     (death)was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States. The death rate was high in people younger than 5 years old, 20-40 years old, and 65 years and     6     (old). The high death rate in     7     (heath) people, including those in the 20-to 40-year-old age group, was a unique feature of this disease.

While the 1918 H1N1 virus has been produced and evaluated by modern science, the features that have made it so deadly are got well understood. With no vaccine to protect against influenza infection and no medicine     8     (treat) secondary bacteria infections, control efforts worldwide were limited to non-medical methods,     9     separation, quarantine(检疫),good personal hygiene, and ban on public gatherings,    10     were applied in heavily infected areas.
