3 . Traditional Chinese Medicine, or TCM, has been around for thousands of years and integrates Taoism(a nature-based philosophy) with elements of Buddhism and Confucianism. Centered around the core belief is that qi is the essential energy that flows through our bodies and powers all human life.     1    

The first suggests that everything about a person is interrelated.     2     And they affect one another because of this interconnection.

The second assumes that every person is part of the natural world, and in so being, is affected by everything from the time, the place, the season, to one’s age, genetic disposition(组成), and physical condition.

The third states that, like all things in nature, we are regenerative(再生的) and have the inborn ability to heal our bodies.     3    .

The fourth is that prevention is the key to staying well.     4     Do not ignore the warning signs. In this way, you can prevent a more serious condition from developing.

    5     They include herbal medicines and diet, foot reflexology (反射论) massage, tai chi, acupuncture, and acupressure (针压法) — to name a few of the more well-known ones. These methods are used to promote the unrestricted flow of qi throughout the body, which is said to promote health. They are also used to balance the opposing forces of yin and yang, believed by Taoists to be found in all things.

A．Taking physical examination regularly does not work

B．TCM is based on four key principles

C．The connections are unnatural enough

D．To achieve and maintain good health, TCM employs a number of methods

E．Listen to our bodies and making adjustments when necessary

F．Unlocking this ability is the key to regaining and maintaining good health

G．One’s physical body, emotions, mind, and spirit are all interconnected

4 . We know you care about your family and want the best for them. You want them to always feel safe and protected. Therefore, you’re expected to get trained for first-aid skills to care for them.     1    

When you take a first -aid course, you will understand how important it is to be prepared for the unexpected.     2     In fact, having more than one kit (工具箱) and placing them in your home, your car and somewhere else may be an action that will benefit someone greatly in the future.

    3     For example, if your child has a cut, you will know which cream to use to prevent further infections (感染). If you know the signs of a heart attack, you may save a life by giving immediate aid.

Knowledge of first aid will not just help the members of your family.     4     Having that first-aid kit on hand will be convenient, and having the knowledge to deal with the situation at hand will be even more helpful in dealing with the injury or illness.

By getting trained in first aid, you will show family members how important it is to be able to care for others during emergencies.     5     In this way, everyone will be prepared to deal with the unexpected.

A．It’s important to keep up with first-aid trends.

B．Packing up a first-aid kit will be your first step.

8 . Scared of needles? Then you might be interested in a new injection-free (免注射) way of taking the COVID-19 vaccine. By simply inhaling (吸气), your invisible shield against corona-virus is formed. It’s as simple as sipping your favorite bubble tea!

The new dose is an aerosolized (雾化的) version of the current COVID-19 vaccine. In other words, the only difference between the new vaccine and the current one is the way the drug is delivered. China’s CanSino Biologics, the company that produces the aerosolized vaccine, said on Sept 4 that it has been permitted for emergency use by the country’s top drug regulator (药物监管机构). It is the first aerosolized vaccine to be approved for public use in China. The vaccine will be used as a booster (加强针) only, according to the company.

An aerosolized COVID-19 vaccine is not only easy to administer (给与药物), but it also offers protection in a unique way, said experts. Sunney Xie Xiaoliang, a biophysical chemist at Peking University and academician of the Chinese Academy of Science, said during a recent forum in Beijing that aerosolized vaccine could be an effective way to protect against respiratory (呼吸道的) diseases in the future. Corona-viruses usually enter the human body through the nose and mouth. Delivering vaccine this way can increase immune responses at the location where viruses enter, according to Xie.

A recent study published in August revealed more advantages. It showed that when given as a booster, the aerosolized vaccine stimulate a stronger antibody response than an injection would. It thus claimed that aerosolized vaccine may be a valuable addition to the existing vaccines.

Marty Moore, co-founder of Meissa Vaccines in Califormia, US told Nature that the approval of the aerosolized vaccine in China confirmed the need for vaccines delivered through the mouth and nose. “That’s the direction we need to go globally, and the United States needs to catch up,” Moore said.

10 . Plenty of people hate needles simply because they do not want the discomfort of injection. A new invention could help — for those who are needle-shy, how about taking a pill instead?

Two of the most successful covid-19 vaccines, from Pfizer-BioNTech and Moderna, need to be administered via injections because their active ingredients are fragile molecules of mRNA, which would be quickly destroyed by acids in the stomach if administered orally.

Aware of these challenges, Robert Langer and Giovanni Traverso, engineers at the Massachusetts Institute of Technology (MIT), wondered if it might be possible instead to send mRNA into the stomach inside a protective capsule that is engineered to inject patients from the inside, where they would feel nothing.

The device they invented is the size of a large pill, encased in gelatin (明胶) and shaped like the shell of a tortoise. It carries a needle that is engineered to stick into the lining of the stomach only when the device’s flat section sits level to it. And the needle can then inject its payload painlessly into the stomach wall.

The researchers knew, however, that this trick alone would not be enough for safe passage of the delicate molecules into cells. Naked mRNA is not readily taken up by cells, but needs to be encased inside a protective envelope to gain entry. So, to investigate further, the engineers worked with colleagues at MIT and found three polymers (聚合物) that could carry the mRNA payloads successfully and also support a transfer into living cells.

The engineers loaded these polymer-encased mRNA molecules into their turtle-shell pills, which were then swallowed by six mice. As expected, they subsequently found evidence that the mRNA had transferred successfully into the stomach tissue of all the mice. The researchers then went on to test their technology on pigs, which have stomachs that are very similar to those found in humans. They introduced their turtle-shell pills into three animal sand studied their stomachs a day later. Two showed clear evidence of the mRNA having entered their cells. One did not.

The device shows the potential to get mRNA into the body without the need for an uncomfortable injection in the arm. More work is needed to understand why one trial in the pigs failed to yield results.
