1 . Called the 4th industrial revolution, 5G will likely bring huge changes to our daily lives. Most importantly, it seems set to revolutionize healthcare.
One of the most exciting and publicized uses of 5G is telesurgery (远程手术). This is when a doctor remotely performs surgery on a patient. They may not be in the same room, nor even the same country! In January 2019, the world’s first remote surgery was performed in Fujian province. A doctor controlled robotic arms through a 5G network to remove the liver of a laboratory test animal. Two months later, China completed its first 5G-based human brain surgery between a doctor and a patient located more than 4,000 kilometers away.
Team leader Tian Wei told Xinhua News Agency, “The combination of 5G technology with surgical robots is a huge technological advance that will help us share our skills with more patients in distant regions.”
“People across society can now have access to top medical resources. In the future, using robots and 5G will be common. The medical community will be smarter,” he added.
These advances were only possible with 5G. The high speed of the network means there is no meaningful latency between a doctor’s movements in one place and a robot’s in the other. This allows doctors far more precision than on a 4G network. It’s the same as playing a computer game online. Slow connections mean trembling shaking and unpredictable movements.
5G will also bring everyday benefits to healthcare. Before treatment, 5G will support a high number of high-definition (高清晰度的) video calls with doctors and provide immediate advice to those who can’t visit hospital. After being treated, wearable devices will send data in real-time to doctors, allowing hospitals to monitor recovering patients from their homes.
5G technology aims to ensure everyone has access to good healthcare. But as 5G is rolled out, we may realize world where robot operations and home healthcare become common.
1. Which of the following best describes 5G technology from Tian Wei’s words?| A．5G will make good healthcare available to more patients. |
| B．It is hard to say whether 5G will be widely used in the future. |
| C．5G has great potential in various fields including community. |
| D．It remains doubtful about using robots and 5G for surgeries. |
| A．Rush. | B．Delay. | C．Speed. | D．Mistake. |
| A．Its precision allows patients to recover more quickly. |
| B．It provides doctors with more personalized treatments. |
| C．It is more convenient both for patients and doctors. |
| D．It will save a lot of energy to go to the hospital in advance. |

2 . If you're out for a run, what difference does it make if you're able to tough it out for another 50 seconds? If you're less than a minute from the top of the hill, that extra time can make the difference between having reached your goal and snatching defeat from the jaws of victory.
How do you get those extra seconds of energy? A research team at the Texes Tech University developed a study to measure what effect listening to music would have on exercise tolerance. The researchers based the study on a stress testing. As part of the testing, they noted any changes in heart rate and blood pressure as participants underwent physically stressful exercise.
The tests were done on treadmills (跑步机), which increased in both speed and incline (坡度) through three stages. In the final stage, the treadmills moved at 10 miles per hour at a 14-percent grade. Most of these tests were designed to last up to 40 minutes. The average gym-goers lasted 30 minutes. For this study, they divided 127 participants into two groups. One listened to upbeat(快节奏) music, while the other group had earbuds in but did not listen to music.
The group that listened to music was able to outlast the non-music group by an average of 50.6 seconds. Again, being able to go an extra minute may seem like a no-brainer ,but “after 30 minutes, you feel like you are running up a mountain, so even being able to go 50 seconds longer means a lot," said the study's lead author, Waseem Shami, MD.
The study has confirmed something runners and gym-goers have suspected for years: Listening to music during workout can be beneficial to your endurance. "Our findings reinforce the idea that upbeat music can help you exercise longer and stick with a daily exercise routine," said Shami. When doctors are recommending exercise, they might suggest listening to music, too."
1. Why did Shami’s team conduct the research?| A．To test the effect of music on health. | B．To know the cause of failure in sports. |
| C．To improve runners' exercise tolerance. | D．To record the body change of participants |
| A．They ran much faster than average runners. | B．They created a new record of indoor sports. |
| C．They could run a little longer with music on. | D．They all enjoyed extreme physical challenge |
| A．A dull activity. | B．A foolish action. |
| C．A demanding task. | D．An easy practice |
| A．Developing a daily exercise routine. | B．Listening to music while working out |
| C．Participating in physical stress testing. | D．Taking exercise as doctors recommend. |
3 . Confucius, a famous teacher , was a politician and philosopher who lived in “Spring and Autumn Period”. During his lifetime, he planted the seeds for China’s transformation by teaching thousands of people. Today, he is thought to be one of the world’s greatest teachers.
Confucius grew up in a poor family. As he grew up, Confucius worked to help his mother earn money. When he wasn’t working, he would read. His favorite thing to do was to learn. His mother saw this and did her best to help him learn. One day, rich families noticed how smart he was and offered him jobs counting their money and keeping track of their crops.
Confucius did this until he was 30 years old, but he always wanted to do more. He didn’t like the way rulers treated their subjects. He wanted to find a way to help people who were less fortunate than he was. Later, he founded the philosophy “Confucianism”. Confucianism states that by educating yourself, loving your family, and respecting tradition you could become a better person. Confucius believed a person could achieve these things by practicing self-discipline. For the rest of his life, Confucius traveled and taught the people of China about self-discipline and the importance of education. He even opened China’s first school that taught both the poor and the wealthy as equals. Although he became very famous among China’s lower classes, the rulers of China never accepted his teachings. Eventually, his philosophy of self-discipline helped China unite under one ruler and finally find peace. Today, Confucius is celebrated all over the world for his philosophy of education, equality, and peace over war, money, and injustice.

4 . As the novel coronavirus outbreak interrupts businesses and everyday life for billions around the globe, massive conferences have moved online. The new form creates numerous technical and organizational challenges, but it also offers opportunities-for reaching wider audiences, reducing the carbon footprint of meeting travel and improving diversity. For some meetings, the switch may be lasting.
The scientific community is “ making lemonade out of lemons,” an expert says. “ Scientists are making use of a situation that’s really quite horrible and providing people a way to connect.”
In many ways, virtual conferences offer a better experience, says Altman, associate director of the Stanford Institute for AI. Altman’s institute had planned an inperson conference in April, but COVID-19 forced organizers to change it. They threw together a virtual conference to discuss how AI can help scientists fight the ongoing pandemic (流行病).The event was a great success. The original conference would have drawn a few hundred attendees, but 30,000 people watched the online version.
Altman says the virtual environment allowed hosts to better control the flow of discussion and questions from the audience. By privately messaging one another behind the scenes, they were able to make adjustments (调整).During the audience question period, the hosts didn’t open up the virtual floor for anyone to speak. Instead, they asked the audience to type their questions and screen the most insightful (有深刻见解的)ones.
Scientists acknowledge that virtual conferences can’t completely replace the conference experience. Virtual meetings might lose some of their appeal once stay-at-home requirements loosen. Even so, the success of some scientists further strengthens the society’s march toward virtual meetings.

5 . One of the most inspiring quotes I ever heard was by Brian Tracy. He said: “The difference between successful people and unsuccessful people is that successful people fail many more times than unsuccessful people.” I personally experienced its wisdom right after my first book was published. Like many authors, I expected hundreds of bookstore customers lining up for me to sign copies for them. I’m afraid to say, it didn’t quite happen like that.
My first signing was arranged at the largest book store in the city. Filled with anticipation, I was put into a private signing room in the beautiful store. However, not a single customer entered the room. As each minute passed, I became increasingly anxious.
After 90 minutes of long waiting I was absolutely distraught.
For the four years writing the book. I had felt a sense of mission and purpose like never before in my life. Working a full 8-hour day in my clinic. I had to get into bed by 9:30 pm every day, so I could wake up at 5:30 in the morning and have two hours of writing before heading into my clinic. Before I ever began each writing session, I would close my eyes for 10 minutes and then whisper, “Please grant me the words to touch just one person’s life.”
Now sitting there alone at my first book signing, I wondered if my entire life wasn’t just a big joke. At that moment, just when I couldn't feel any worse, a middle-aged couple walked into the room. I managed to hide my emotions and introduced myself and my book. The couple turned to each other, and the husband nodded to his wife. She then told me, “I think we’ll get the book.”
“We’re buying it,” she said hesitantly, "because we lost our son two years ago. Maybe your story will help us get over it.”
At that moment, I knew if I never sold another copy of the book, my four years of writing it had served its purpose. Although I would have many more challenging years until my book caught on and sold well, this couple’s story was all the motivation I needed at that point to keep me moving ahead.

6 . Do you think alien beings exist somewhere in the universe? It seems like Mars, our closest neighbor, has inspired the most science fiction as the place where aliens are most likely to come from. Recent Mars probes (探测) have shown us that there is no life on that planet—at least not now. But that does not mean that life does not exist elsewhere—after all, the universe is really big. A lot of scientific research is going on in the search for “extraterrestrial life”.
Think about it—why should the seven billion people on this little planet be the only living beings in the universe? It would, in fact, seem logical that this is not the case. So scientific research in this matter is based around the idea of finding other planets that have environments that can support life —environments similar to the Earth. The search is on for the evidence of the existence, or earlier existence of life: from very wise beings to simple organisms (有机物).
So far, there have been a number of theories as to which planetary bodies may have an atmosphere that can support such life and therefore deserve closer attention. As for places within our own Milky Way Galaxy, it has been assumed over the decades that Mars and Venus, as well as some of the moons of Jupiter and Saturn, may have been hosts for life. Now, as technologies have improved and we can obtain measurements of the composition of the atmosphere on extra-solar planets, the chances of finding “alien” life forms are increasing.
There has been a theory that some of the planets in the habitable zone of the red dwarf star Gliese 581 may be able to support life. In 2007, scientists discovered exoplanet Gliese 581c—and felt that its atmosphere was most suitable for supporting life. But further research revealed that it would not. Now, attention has been turned to Gliese 581d, at the outer edge of the star’s habitable zone. The main standards for deciding whether a planetary body can be life-supporting are atmospheric conditions which allow the existence of water. Gliese 581 is about 20. 4 light years away from the Earth, so even if life does exist there, the distance would mean that communication would be unlikely.
Having said this—who says alien life forms (if they exist) need water?

7 . It was about seven years ago. I just picked up my threeyearold daughter from the nursery. I was weighed down with shopping bags, and with my daughter’s things. We arrived at a pedestrian crossing and she pressed the button. In the distance, I heard alarms, told my daughter to wait and watched a police car approaching.
Little did I know, as the_green_man flashed, that my daughter had begun to run into the road. I watched the police car speed toward us—that’s when you sounded your horn and waved wildly to me. My daughter was about a meter from the path of the police car, hidden from their view by your car.
I screamed her name and ran toward her. She stopped and was shocked by the rush of the police car as it sped past. She wondered why you had blown your horn, asking, “Mom, why was that woman so rude？” not realizing you had saved her life.
She wondered why I picked her up and burst into tears. My legs gave way as I reached the other side of the road. I should have followed my “wait” with a hand on her shoulder, or an explanation of why we were ignoring the green man this time, especially as I had in effect conditioned her to cross the road at the sight of the green flash.
I beat myself up for months, and still do, with flashbacks and horrible assumptions about what might have been. But for your sounding your horn, seeing what I hadn’t seen, I would have been left a mother on the other side of the road, totally broken. I apologize for putting you in that position—I can imagine that it upset you, too. You saved her life and I am so grateful.

8 . Mirroring body language is a way to bond and to build understanding. It is a powerful tool that we use without even knowing it.
The most obvious forms of mirroring are yawning and smiling. When you see someone yawn, you are likely to yawn immediately. Smiling is also pretty contagious-seeing a smiling person makes you want to smile too.
Mirroring body language is a nonverbal way to say “I am like you, I feel the same”. Research shows that people who experience the same feelings are likely to trust, understand and accept each other.
Women have the natural ability to pick up and understand body signals. Therefore, it is not surprising that a woman is more likely to mirror another woman than a man is to mirror another man. That's why women are regarded as better talkers, even if they might not really have more close friends.
It is interesting that when a man tries to mirror a woman's body language while she is talking, he may seem to her as caring, intelligent and attractive.
Mirroring body language is an excellent way to build trust and understanding quickly. If you want to set up a connection with a new person, mirror his or her gestures, sitting position, tone of voice and talking pace. This will make them feel that there is something about you that they like.
While mirroring body language gains you acceptance, you still need to take into consideration your relationship with the person you are mirroring. If you are in a lower social position and are mirroring the body language of your boss, he will view you as arrogant. However, if you want to defeat those who are trying to prove superior to you, mirroring their body language will help defeat them and change their position.
1. What does the underlined word “contagious” in paragraph 2 mean?| A．Affecting each other. | B．Powerful to show one's feelings. |
| C．Attractive to the others. | D．Being gentle to people around. |
| A．send wrong messages | B．hide true feelings |
| C．win others' acceptance | D．avoid misunderstanding |
| A．You will appear very attractive. | B．It will help to soften his position. |
| C．You will seem unacceptably proud. | D．It will be a good way to build trust. |
| A．It is important to copy the others' gestures. |
| B．Why women are regarded as better talkers. |
| C．Men is not good at nonverbal communication. |
| D．Mirroring body language can be a useful tool. |
9 . Pang Hui placed a few more pairs of chopsticks on the table for a family dinner, though she did not expect her big family of seven would use them as serving chopsticks.
Surprisingly, her 75-year-old father, who used to shrug off the idea of serving chopsticks, became a firm supporter this time, said Pang, 40, from Beihai, a coastal city of South China's Guangxi Zhuang Autonomous Region.
Chinese people often share dishes, and diners use their own chopsticks to serve themselves food from the shared dishes, a tradition now being challenged by the outbreak of COVID-19.
"We feel a sense of crisis as well as the urge to desert our old habits when we see reports of family infections, " Pang said, pointing to the reports of the virus spreading via droplets and close contact.
Local governments are helping to encourage a shift, too. On Feb. 13, 2020, local authorities of Beihai started a campaign promoting serving chopsticks and spoons, which will avoid cross infection caused by the use of personal chopsticks.
Similar measures were also adopted in other cities like Beijing, Shanghai and Hangzhou. Taizhou city in East China's Jiangsu Province even standardized the colours of serving chopsticks and spoons to help diners differentiate (区分) them from personal ones.
The practice of eating wild animals has been targeted by the government, which remains present in certain areas.
China stopped the illegal trading and transportation of wild animals shortly after the outbreak. The move became a permanent ban on Feb. 24, 2020, when the country made a decision on thoroughly prohibiting (禁止) the illegal trading of wildlife and the consumption of wild animals.
Li Bo, with the Hainan International Center for wildlife Protection, said wild animal consumption could lead to the faster extinction of particular species, damage the ecological balance and harm people's health.
" The epidemic(流行病) could become a turning point to eliminate the bad habit, " Li said.

10 . Like you and your pet dog, plants are living things: they eat, drink, and grow. Unlike you and your dog, they can't run away, use fists or teeth, or hide under the covers when they're threatened. But they can fight back.
Why would a plant need to fight back? To avoid being eaten, of course! Plants have several ways of protecting themselves. A plant can grow in a hidden or hard-to-get-to place. Think of plants you've seen growing on steep, rocky cliff (悬崖). Or, a plant could make only some parts of itself attractive to hungry insects and animals. For instance, if a plant produced really tasty leaves, herbivores (creatures that eat only plants) might eat the leaves instead of the seeds, which the plant needs for making more plants. Some plants have sharp or slippery (滑的) parts that discourage insects and other animals from getting too close, like the thorns(刺) on a rosebush.
But the most interesting way that plants fight back is by using chemicals. Plants take minerals from the soil and combine them into chemicals that do a lot of work. For example, plants produce chlorophyll(叶绿素), which helps convert sunshine and water into the sugars that plants eat.
They also produce chemicals to help protect themselves. One kind of tobacco plant releases a chemical into the air whenever small bugs begin to eat it. The chemical signals large bugs, saying "Dinner's ready!" The big bugs come to eat the little ones and save the plant.
Most plants use chemicals in a more direct way against their enemies. In other words, plants make poison.
