1 . Since 2001, robotic tools have revolutionized the practice of surgery. They have greatly reduced the stress and physical demands normally placed on surgeons and have made certain procedures possible.
One example is "keyhole surgery", or minimally invasive (微创) surgery, which normally requires surgeons to stand at awkward angles and make difficult movements with their hands to make a cut inside the patient. But in June 2022, surgeon James Ansell used 3D glasses and two joysticks (操纵杆) to control four robotic arms to perform a procedure to remove a cancerous tumor (肿瘤). "My colleague said . that this feels like cheating, " Ansell said to The Guardian.
Another area of surgery that has had major technological breakthroughs in recent years is telesurgery. Telesurgery, or remote surgery, is the use of technology that allows a surgeon to perform a procedure on a patient not in the same physical location.
Normally, telesurgery relies on a wired connection due to concerns of harming the patient if a wireless connection were to drop during surgery, but China made several advancements in wireless telesurgery based on 5G technology.
China achieved the first 5G-based remote operation in March 2019 involving a brain surgery procedure between a surgeon in Sanya and a patient in Beijing, a distance totaling nearly 3, 000 kilometers, reported CGTN. More recently, a team of surgeons successfully completed remote micron-level eye surgery on rabbits located in a different city, reported China Daily. The rabbits were at the Sun Yat-sen University in Guangzhou, Guangdong province, whereas the surgical team who operated on them via a 5G robot were at the Hainan Eye Hospital in Haikou, Hainan province.
Looking to the future, people hope that remote surgery could become commonplace to help heal injured soldiers on the battlefield while keeping surgeons at a safe distance. Some even believe that robotic systems, combined with AI, could one day surpass human surgeons. In 2022, engineers at Johns Hopkins University in the US used their Smart Tissue Autonomous Robot (STAR) to suture (缝合)the ends of a severed intestine (断肠) in four pigs, showing that certain procedures can be done autonomously by robots.
But, given current technological limitations and the high costs of these robots which can cost millions of dollars, the complete robot takeover of surgery may still be a while off.

2 . Guidelines on How to Use AED
An automated external defibrillator (AED)is a device that is strongly recommended to use in time to analyze the heart rhythm, provide electric shock when necessary and save life when SCA (Sudden Cardiac Ares) patient is discovered whose heart unexpectedly stops beating without any warning.
1. Check the patient’s condition, call for help and look for an AED:
If a person collapses in your presence, he or she has likely experience shock or fainting due to SCA, consistently pulseless, unresponsive and not breathing. Then call for medical help immediately and let the patient lie flat on the ground and ask someone nearly to get an AED. Place the AED net to the victim’s left ear, switch on the power and quickly check if the machine and accessories are working property. Voice instructions will sound.
2. Attaching the AED pads
Attach the AED pads to the designated locations of the victim’s bare chest following the animation and voice prompts. The rule of anterolateral AED pad placement for adults: the right pad is placed on the upper right side of the chest, while the left pad is on the lower let side, 7cm below the left armpit. For children under 8, the anterior pad should be placed lo the middle point of the line connecting the two nipples, and the posterior pad on the opposite side of the back.
3. Analysis of the heart rhythm
Insert the electrode pads wires into the AED host device. Press the “Analyse” key and it will automatically analyze the patient’s heart rate to determine the necessity of an electric shock. Never touch the victim during this process. Even a slight touch can affect the analysis. Upon completing the analysis (S-15 seconds). AED will recommend whether to perform defibrillation.
4. Delivering a shock
If an AED shock is required, then a fully automatic APD will ask you to step back and deliver the electric shock automatically. In the case of a semi-automatic AED device, you need to press a button to deliver the shock. If the effective heart rhythm is not restored, the operator should conduct CPR (心肺复苏), and then analyze the heart rhythm again. Repeat until emergency medical personnel arrive.

3 . There was a time when the word “surgery” used to scare people, and they would try their best to avoid a surgical procedure. The feeling is understandable, as the idea of a large cut on your body is discomforting in many ways. However, thanks to the advances in medical science, surgical techniques have improved considerably.
Compared with the traditional open surgery, minimally invasive surgery (微创手术)has several benefits to offer. Not only is the procedure quick and less painful, but also ensures rapid recovery. Now, surgical procedures, either big or small, are done within a few minutes to a few hours. The best part about the minimally invasive surgery is the painless procedure. The advanced techniques are helping with quality treatments to patients who have to undergo (进行) surgical procedures.
Unlike the traditional open surgery that requires a large cut, a surgeon makes multiple tiny cuts of less than an inch. For the process, the surgeon uses small surgical instruments, such as a tiny tube with a mini camera at one end. Once the surgeon marks the cuts, he then passes the tiny tube through one of the cuts. The doctor monitors the images taken by the mini camera on the screen and uses them as a reference. These images give the surgeon a clear picture of the area undergoing the surgery. After the surgery, the surgeon cleans the cuts and sometimes places a bandage for additional support.
Minimally invasive surgery has become the first choice of patients with multiple medical conditions. In fact, it would not be wrong to say that these surgeries are now the standard surgical procedures for many routine operations. Whether you have a minor issue or want a surgical intervention for a major health condition, it is the best option.

4 . As medical science develops rapidly with new technology, what is left for the doctor to do?
For medical humanist Dr. Abraham Verghese, the answer is simple: Spend more time getting to know your patients as people. Take the time to read a poem and other literature. Do your part to bridge the gap (鸿沟) between the two cultures of science and the humanities.
It takes a doctor who knows a patient’s life history well to make the best use of these tools, Verghese said. And that means paying more attention to human character.
Verghese said machines “have gone beyond human beings in their ability to care for the patient,” that is, in diagnosing illnesses and indicating the best treatment.
But doctors can awaken the human spirit, the knowledge of human beings and their motivations (动机), which can pull together a life picture of a patient and understand them as more than a collection of symptoms.
Case history: A 64-year-old man was admitted to the hospital after repeated falls, pains, and the loss of two teeth that just fell out, with no obvious cause.
What was wrong? Was it his medicine? Was it alcohol abuse (酗酒)?
The man rapidly improved after being hospitalized. It turned out he had bachelor scurvy, a disease among older men who live alone, which results from a lack of nutrition (缺乏营养).
“He was surviving on no fruits or vegetables, just alcohol and processed meats, I would guess,” Verghese said. “My point here is that this diagnosis, as clever as it was, also might have been made much, much earlier had we had a good relationship with this patient and had some sense of who that person was, as an individual.”
1. What is Verghese’s suggestion for doctors?A.Use machines less frequently. |
B.Remember to care for patients. |
C.Try to make an early diagnosis of patients. |
D.Keep up with the development of technology. |
A.It needs to be improved greatly. |
B.It will replace doctors sooner or later. |
C.It may give patients incorrect treatment. |
D.It is of great help in diagnosing illnesses. |
A.He lives on his own. |
B.He lives a healthy lifestyle. |
C.He suffers from a rare disease. |
D.He is a regular visitor to the hospital. |
A.By giving an example. |
B.By making comparisons. |
C.By providing explanations. |
D.By showing facts and opinions. |
A.To introduce some medical tools. |
B.To advise doctors to get to know patients better. |
C.To describe the development of medical science. |
D.To show the importance of machines in medical operations. |
5 . Many people love the Halloween season, particularly young ones. It’s not hard to understand. The Halloween season is a time for fun-sized candy, giving rocks to trick or treaters, apple cider donuts, and frights. The very last-frights, are generally all in good fun. But can they be dangerous? Can someone be scared to death?
The key factor in an imagined scare-caused death is a little chemical that anyone who’s played a particularly intense game of hide-and-seek is very familiar with: adrenaline (肾上腺素). Fear puts the body in a state of severe emotional anxiety, which in turn causes the autonomic fight-or-flight response.
The fight-or-flight response is an evolutionary defence mechanism (机制) which acts in your best interest when there is a noticed threat. You sweat a lot, your anxiety is exacerbated, your blood glucose (葡萄糖) levels are increased, and your heart rate is higher. Like a cornered animal, you’re a bit less reasonable, a bit stranger, but a bit more ready to survive.
Now, back to the adrenaline. Adrenaline causes all of these processes, but there’s just one organ, which, if overloaded, can lead to sudden death. The human body doesn’t immediately come to an end as soon as a kidney (肾) fails, but when a heart stops working, the whole business fails. This is what happens to your body during an adrenaline rush.
Adrenaline causes calcium (钙) to enter the heart at a higher rate, and when there’s more calcium rushing through the heart, it has harder time resetting to its normal resting rate. This can cause a dangerous condition, which prevents blood from pumping to the rest of the body. Without immediate treatment, this can lead to sudden death.
Of course, such cause of death isn’t unique to being scared. Any event that increases one’s adrenal level could lead to this dangerous condition. So if you are planning on scaring others the next Halloween season, be sure to do it in a controlled setting, especially if you have a history of heart problems.
1. What do we learn about the fight-or-flight response mentioned in Paragraph 2?A.It makes us think in a better way. |

6 . In US emergency rooms (ER), the average wait time to see a doctor is more than two hours. There are more patients in need than there are doctors, nurses and other staff to help them. Many parents have suffered through hours in the ER with a sick, upset child, only to get sent home because their case is not considered urgent. What if there was another choice—like a house call from an intelligent machine?
Now, a new study shows that AI systems can assess a child’s medical chart and come up with a diagnosis, a determination of what is wrong with that patient.
The study took place at Guangzhou Women and Children’s Medical Center in southern China. First, a team of doctors reviewed 6, 183 medical charts. They summarized the information in these charts into a list of keywords linked to disease-related symptoms or signs, such as “fever”. Researchers then taught these keywords to the AI system. Once trained, the system scanned children’s charts for the key terms, checking if they were present or not in order to come to a conclusion. Finally, it offered diagnoses based on the charts, narrowing down from among 55 illness categories.
It agreed with real doctors about 90 percent of the time. It was especially effective at identifying illnesses of the ear, nose and throat. For these upper-respiratory infections, the Al system got it right 95 percent of the time.
Dongxiao Zhu, an assistant professor of computer science at Wayne State University who did not take part in the study, however, sees this as “augmented intelligence (增强智能)” rather than “artificial intelligence”, because the system handled only 55 illness categories. Compare that to thousands of possibilities in the real world. The machine cannot yet get into the more complex aspects of a medical decision.
Zhu is also concerned about the amount of human work that went into the study—namely, the time and energy spent by human doctors. They spent hours grading the machine’s assessments and comparing them to their own. It’s no wonder that the process took four years. Considering that, it may be a while before you can skip the ER and see a robot-doctor instead.

7 . Jennifer Udler was in the middle of a 50-minute session with a patient when it started to rain. Walking and talking about anxiety and stress, she and her teenage patient got wet. But when they made it back indoors, Jennifer said, “Hey, look at us! We’re wet, but we got through it! Now you can use that next time you have anxiety before and during an event.” This kind of insight is key to her practice.
Jennifer, a social worker whose practice focuses on adolescents, has been a therapist(治疗师)for 20 years. For most of that time, she practiced in a traditional office, but she noticed how easy it was for her running partners to open up about their problems. After doing some research, in 2013, Jennifer founded Positive Strides Therapy, where she conducts sessions while walking outdoors. She conducts all of her sessions outdoors and in all kinds of weather.
“When somebody asks me if I specialize in walking therapy, I say, ‘No, that’s how I practice,’” Udler said. “I specialize in family systems theory. Walking in the park is just where I practice.”
Despite the lack of formal research, Jennifer believes strongly in the benefits, saying that it can be helpful. “We’ll be talking about ‘moving forward’ as we are actually moving forward on the path, building muscle memory of how they can move forward and leave the anxiety behind.”
And outdoor walking therapy doesn’t just benefit teens. Jennifer says the adults in her practice welcome the humanizing effect of taking therapy outdoors.
1. What lesson did Jennifer teach her teenage patient through the rain?A.Rain and suffering are a part of life. | B.She is ready to help the young man. |

Therapy dogs are dogs that are trained to give comfort and love to people in unfortunate situations. They are often used to help people in hospitals, retirement homes, schools and disaster areas. Whether or not a dog is suitable for this line of work is based on its personality. Because therapy dogs must work with many kinds of people, such as young children or the elderly, they must have patience.
During World War II, a soldier named William Wynne found a dog abandoned (遗弃)on the battlefield. He became friends with the dog and named it Smoky. When Wynne became ill and entered a hospital, his friends brought Smoky for a visit. Smoky became so popular with the other sick soldiers in the hospital that he was allowed to stay. The doctors in the hospital used Smoky to help cheer up the patients. After the war ended, he continued to work as a therapy dog in the United States.
In the 1970s, an American nurse named Elaine Smith started a program to train therapy dogs. Smith noticed that patients in hospitals seemed to get better faster when they were around dogs. Many other doctors and nurses noticed that having animals regularly visit hospitals helped lower stress and blood pressure among patients. In the 1980s and 1990s, other animals also started to help the sick. Cats, birds and rabbits have become “therapy pets” and they are now used in many hospitals around the world.
Today, therapy pets not only help injured soldiers, but also help children with reading disabilities by providing an audience that won’t look down upon them. Some therapy pets are used to work along with the doctor to help the patient learn to walk again after a serious injury.
1. What dogs are most suitable to be therapy dogs?(No more than 5 words)2. Why was Smoky allowed to stay in the hospital?(No more than 10 words)

10 . Heart disease is one of the major killers in the world today. Many who suffer from it must have heart transplants(移植). However, it's difficult to get a suitable heart donation, and even if a patient survives the wait, his or her body often rejects the heart.
But there is now new hope for sufferers of heart disease. According to a study published in the journal Advanced Science, researchers from Israel's Tel Aviv University printed a 3D human heart on April 15, 2019.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” Professor Tal Dvir told CNN.
Unlike the previous 3D-printed heart structure, the new heart is complete with cells, blood vessels(血管), chambers(心室) and other structures a heart needs to function normally. But scientists still have more to figure out before the 3D-printed heart can be fitted into the body. For one thing, the experimental heart is only the size of a thumb. And, although it can contract(收缩) like a muscle, it cannot pump out blood like a real one. At present, the heart prototype(样品) is like a tiny airplane that has all of the right parts, but can't fly.
However, the development is still regarded as a major breakthrough in medicine.
In the experiment, the researchers turned human fat tissue(脂肪组织) into human heart tissue with stem cell(干细胞) technology. The tissue was then turned into “bio-ink” for a 3D printer to ensure that tissue in the heart came from the patients themselves. So ideally, if it were to be placed in the body of someone in need of a transplant, there would be less risk of organ rejection.
“Patients will no longer have to wait for transplants or take medications to prevent their rejection,” researchers told USA Today. “Instead, the needed heart will be printed, fully personalized(个性化的) for every patient.”
“Maybe, in 10 years, there will be organ printers in the finest hospitals around the world and these procedures will be conducted routinely,” Dvir said.
