When it comes to national parks, people often link them with those famous landmarks     1     (recommend) in tour and entertainment guides.

Recently, however, national parks in Canada appear on the prescriptions (处方) given by Canadian doctors.

According to CBC, a medical program named “PaRx”     2     (launch) in January by the government. Under the program, over 1,000 physicians, nurses and other medical     3     (professional) in Canada can prescribe the annual Adult Parks Canada Discovery Pass from the Canadian parks authority.     4     the pass, patients can gain free access to over 80 national parks, national historic sirs and national marine conservation areas around the country.

Many     5     (science) studies have shown that people     6     (spend) at least two hours a week in nature have     7     (good) health than before. It contributes to increasing life expectancy (预期寿命) and energy, reducing pain and stress, as well as improving heart health.

“We’re hoping that our PaRx program not only     8     (improve) patient health, but reduces costs to the healthcare system, and helps to grow     9     number of people who are more engaged in environmental activities,”said Prama Rahman,     10     is a leader of the BC Parks Foundation’s Healthy By Nature Program.

Chinese researchers     1     (develop) a robot designed to help doctors treat the new coronavirus and other highly contagious diseases so far. The machine has a long robotic arm attached to a base with wheels. It can perform some of medical examination tasks the same     2     doctors.

Cameras record the robot’s activities, which     3    (control) remotely so doctors can avoid     4    (come) in close contact with infected patients. Doctors and other medical workers can operate the machine from a nearby room or much     5    (far) away.

The robot’s main     6    (design) is Zheng Gangtie, an engineer and professor at China’s Tsinghua University in Beijing. He told Reuters News Agency that he got     7     idea for the device when the number of cases of the COVID-19 was rising quickly. COVID-19 is the disease caused by the new coronavirus.

Zheng said a friend of his is head of Beijing Tsinghua Changgung Hospital. He said his friend told him that one of the biggest     8    (problem) in dealing with COVID-19 was     9     health care workers treating patients were getting infected themselves. Zheng said he wanted to do something to deal with this situation.

So the engineers gathered a team and went to work on the robotic device. Zheng said the team was able to convert two robotic arms. The new robot is almost     10    (complete) automated. It can even disinfect itself after performing actions involving contact with patients.

In the last seven days I have seen the pressure that the NHS is under. I have seen the personal courage not just of the doctors and nurses but of everyone, the cleaners, the     1     (cook), the health care workers of every description—physios, radiographers—     2     have kept coming to work, kept putting themselves in harm’s way, kept     3     (risk) this deadly virus. It is thanks to that courage, that devotion, that duty and that love that our NHS has been unbeatable.

14 years ago, SARS broke out in the mainland of China, causing some people to be killed or nearly got close to     1     (die). The situation was so severe that there was no time to debate who is to blame. The most     2     (importance) thing for the government to do is to find out the cause of this     3     (dead) disease. They invited all the most famous experts in this field to discuss and quite a few suggestions were     4     (put) forward. Some of the top experts picked out those suggestions and tested them to see whether they were     5     (avail). Doctor Zhong chose one patient who was seriously ill and had little hope of picking     6     and had the new medicine     7     (test) on him. To his great joy, this patient recovered! He made his way     8     his office and telephoned to the top official,     9     (tell) him this exciting news. For     10    (convenient), he moved to live in his office. His method did make sense. Not soon after that, the other hospitals also controlled this terrible disease and kicked it out finally.

After studying a group of healthy individuals for more than 10 years, researchers at the University of Texas     1     (discover) that those who scored     2     (poor) on five simple medical tests were 20 times    3    (likely) to develop heart disease than those with good results. The tests are not all standard,    4     the results will give you a much better and earlier sense of your heart disease risk than the traditional     5     (rely) on blood pressure and cholesterol levels. They can help you change your habits as     6     (need) to protect your heart for life. If you smoke, are overweight, have a family history of heart problems, or have any other risk     7     (factor), ask your doctor about these tests. A standard, 12-lead electrocardiogram, also known     8    an EKG, is non-invasive, painless, and usually takes only five to ten minutes. It’s considered one of the best ways     9     (assess) heart disease risk. Your doctor will place 10 small electrodes     10     measure your heart’s electrical activity on your limbs and chest and will detect any abnormal rhythms and other dangerous cardiovascular conditions.
