1 . An 8-year-old boy I know is small for his age, shorter and slighter than his friends, even smaller than his 5-year-old sister. Concerned about the increasing use and possible risks of growth hormone(生长激素), I asked his mother if she’d considered treating him with it. She replied, “Not really. He’s built like his father, who was short and slight as a boy and didn’t shoot up until college.”
His father, at 41, is now 6 feet tall, though still very slender. He recalls being a reasonably athletic child but without the physical power of his friends, making up for what he lacked in mass with speed and agility. “I enjoyed competitive sports and worked on skills others didn’t have,” he told me, and said he encourages his son to recognize and capitalize on the skills he has.
If only every parent with a short but healthy child approached the matter as sensibly. Experts estimate that 60% to 80% of children who are short for their age do not have a growth hormone deficiency(缺乏) or other medical condition that limits growth. But knowing there’s a therapy available to increase height, some parents seek a medical solution for a perceived problem, even when there is no medical abnormality. They should also know, however, that new research has linked growth hormone treatment to serious unfavorable health effects years later.
Dr. Adda Grimberg, a doctor at Children’s Hospital of Philadelphia, recalled that “Twenty years ago, families were focused on health. They came in with a child who was not growing right and wanted to know if there was an underlying disease. Now, more and more, they’re focused on height. They want growth hormone, looking for a specific height. But this is not like online shopping; you can’t just place an order and make a child the height you want.”
In 2003, the Food and Drug Administration approved use of recombinant human growth hormone for the condition known as “idiopathic short stature”, or short build of unknown cause, which is not a disease. But it has caused a growing number of parents to consider using the hormone to boost the height of their children.
The resulting rush to therapy reflects concerns about a widespread societal bias(偏见) against shortness, rather than a true medical need. Experts have noted that the practice backs up the belief that short stature is unacceptable, leading to an increasing demand for therapy. It is far better, Dr. Grimberg suggested, to help a short child develop coping skills than to buy inches through medicine.

2 . Every day, it seems that some new algorithm (算法) enables computers to diagnose a disease with unprecedented accuracy, renewing predictions that computer's will soon replace doctors. What if computers could replace patients as well? If virtual humans could have replaced real people in some stages of a coronavirus vaccine trial, it could have sped development of a preventive tool and slowed down the pandemic. Similarly, potential vaccines that weren't likely to work could have been identified early, reducing trial costs and avoiding testing poor vaccine candidates on living volunteers. These are some of the benefits of “in silico medicine”, or the testing of drugs and treatments on virtual organs or body systems to predict how a real person will respond to the therapies.
The modeling begins by feeding anatomical data drawn from noninvasive (非侵入式) high- resolution imaging of an individual's actual organ into a complex mathematical model of the mechanisms that govern that organ's function. Algorithms running on powerful computers resolve the resulting equations and unknowns, generating a virtual organ that looks and behaves like the real thing.
In silico clinical trials are already underway to an extent. Heart Flow Analysis, for instance, enables clinicians to identify CAD (冠心病) based on CT images of a patient's heart. The Heart Flow system uses these images to construct a fluid dynamic model of the blood running through the coronary blood vessels, thereby identifying abnormal conditions and their severity. Without this technology, doctors would need to perform an invasive operation to decide whether and how to intervene. Experimenting on digital models of individual patients can also help personalize therapy for any number of conditions and is already used in diabetes care.
The philosophy behind in silico medicine is not new. The ability to create and simulate the performance of an object under hundreds of operating conditions has been a cornerstone of engineering for decades, such as for designing electronic circuits, airplanes and buildings. Various obstacles remain to its widespread implementation in medical research and development.
The predictive power and reliability of this technology must be confirmed, and that will require several advances. Those include the generation of high quality medical databases from a large, ethnically diverse patient base that has both women and men; improvement of mathematical models to account for the many interacting processes in the body; and further modification of Al methods that were developed mainly for computer-based speech and image recognition and need to be extended to provide biological insights.
In recent years American and European regulators have approved some commercial uses of computer-based diagnostics, but meeting regulatory demands requires considerable time and money. Creating demand for these computer-based diagnostic tools is challenging as well. In silico medicine must be able to deliver cost-effective value for patients, clinicians and health care organizations to accelerate their adoption of the technology.

3 . The Rise of Voice Technology
Voice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.
Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.
Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.
To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases where the software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.
To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the software beforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.
Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.

4 . It is the season for taking the time to reflect on what we’re thankful for in life. Spending that time with friends and family to give thanks is what makes the holidays so special. But why should limit it to just a few weeks in the year? Gratitude（感恩）is a muscle we should strengthen year-round to make us healthier, happier humans and leaders.
Gratitude builds empathy. We often take for granted the simple things in life. Those who recognize the goodness in life, no matter how simple or automatic, are more likely to be sensitive to the needs of others and to help whenever they can. Being empathetic to others’ opinions, experiences and backgrounds will make you a better professional, no matter your career.
Through his research, Emmons, a leading researcher, found that grateful people reported feeling healthier, both mentally and physically. Specifically, those who were grateful were 25 percent happier than those who weren’t. In the workplace, well-being（健康快乐）is a crucial topic when it comes to preventing employee burn-out and promoting engagement. Beyond the research that shows that employees who are shown that they are appreciated are more productive by 50 percent, caring for your employees’ well-being is simply the right thing to do. Offering fitness classes or carrying out flexible work schedules are just a few things that, when paired with gratitude, can lead to more productive, engaged and happier working professionals.
Working in a developing, fast-paced industry, we are often surrounded by ambitious people who are always striving（奋斗）for more and better. Gratitude makes us more self-aware. It challenges us to reflect in the moment instead of always thinking about the future. It starts by paying attention to what’s going on in our life, and that true self-awareness is a key factor to being successful in our career.
Gratitude is a powerful tool for making relationships stronger, both at work and in our personal life. People who express their gratitude tend to be more willing to forgive others and therefore able to create relatively long-lasting connections.
During my month-long vacation, I made it a point to be reflective during the time I had without disturbances or deadlines. Part of that was making a mental list of the people, things and experiences I was grateful for in my life. I decided to reach out to my fifth-grade teacher and thank her for being positive instructor and a strong influence on my life.
The old saying goes “It’s never too late to say you’re sorry,” but the same is true of gratitude. Taking the time to thank people for their work, kindness or empathy-whether it was today, last month or many years ago-makes you happier, healthier and more self-aware. And that’s a gift worth celebrating 365 days a year.

| B．The desire to help people in difficult situations. |
| C．The ability to understand other people’s feelings. |
| D．The feeling of pleasure or satisfaction towards others. |
| A．People who have self-awareness can succeed without effort. |

| C．The Way to Show Thanks. |
| D．The Special Holiday of Gratitude. |
5 . Lessons in the Lost Art of Listening
When was the last time you listened to someone? And when was the last time someone really listened to you? I once asked people what it meant to be a good listener. The typical response was a blank stare.
Of course, technology plays a role. People find phone calls interrupting them, preferring text or wordless emoji. Besides, schools and colleges rarely offer classes or activities that teach careful listening. You can join clubs to perfect your public speaking, but who attempts to achieve excellence in listening? The loud unpleasant mixture of sounds of modern life also stops us from listening.
Generally, listening goes beyond simply hearing what people say. It also involves paying attention to how they say it and what they do while they are saying it, in what context, and how what they say is related to you. It’s not about merely holding your peace while someone else holds forth. Quite the opposite. A lot of listening has to do with how you respond—the degree to which you facilitate the clear expression of another person’s thoughts and, in the process, have a clear mind of your own.
Good listeners ask good questions. They engage in exploring the topic, not to divert attention. There are curious questions like “Wouldn’t you agree…?” or “Don’t you think…?” These questions have strong tendencies. They will greatly influence the other person to change his or her view. And you’d better stay away from some personal questions like “What do you do for a living?” or “What part of town do you live in?” Just try to find out what excites people. Ask about the last movie they saw or for the story behind a piece of jewelry they’re wearing. Also good are expansive questions, such as, “If you could spend a month, where would you go?” Research indicates that when people who don’t know each other well ask each other this type of question, they feel more connected than if they spend time together achieving a task.
Because our brain can think a lot faster than people can talk, be careful with the tendency to take mental side trips when you are listening. Smart people’s attention is easily taken away by their own runaway thoughts. They may also assume they already know what the other person is going to say.
The reward of good listening will certainly be more interesting conversations. Researchers have found that attentive listeners receive more information from speakers, even when they don’t ask any questions. We are, each of us, the sum of what we attend to in life. The gentle voice of a mother and the criticism of a boss both ultimately form and shape us. And to listen poorly, selectively or not at all limits your understanding of the world and prevents you from becoming the best you can be.
1. One of the factors that influence listening is that ________.| A．our confidence in listening is decreasing | B．our speech creates a lot of noise around us |
| C．listening skills are seldom taught in school | D．texting causes a better effect than phone calls |
| A．Why the art of listening gets lost by itself. | B．Why effective methods are used in listening. |
| C．How people make themselves well understood. | D．How people can reclaim the lost art of listening. |
| A．Avoid being absent-minded. | B．Come up with curious questions. |
| C．Focus on the speaker’s personal information. | D．Try to find common interests with the speaker. |
| A．Listening and speaking deserve equal attention. |
| B．Good listeners maximize the benefits for themselves. |
| C．Bad listening ultimately contributes to people’s failure. |
| D．Listeners’ clear mind facilitates speakers’ expression of thoughts. |
