1 . How to Feel Connected
It's easy to feel disconnected from what is going on around you in today's fast-paced world.
Consider why you feel disconnected. Knowing what is making you feel disconnected can help you choose the best ways to address it.
Interact with people in person. Technology is a great way to stay in touch, but sometimes you need to spend time with other people in person.
Your loved ones could feel shy, so you may never know how to improve your relationship unless you ask the right questions. Asking them to open the doors can give you some insight on what you can do. Learning this information can help to strengthen your bond.
Show your commitment to them. Simply showing up and being there for your loved ones says a lot about how much you value your relationships. Putting in the time shows them that you are committed and want to stay connected.
Show appreciation. A simple “thank you” goes a very long way. Unfortunately, it is something that people who are close often take for granted. Telling someone you appreciate their time, love, and efforts can strengthen your bond and help you to become more connected.
| A．Ask others what they need from you. |
| B．Sometimes you can feel isolated and distant from the ones you love. |
| C．Be brave to express your love. |
| D．Reach out to people to schedule a time to get together. |
| E．Attending family events, or simply visiting someone once a week can help to strengthen your relationship and keep it strong. |
| F．Targeting your efforts toward those issues allows you to close that distance more effectively. |
| G．You can have a gift delivered to friends on special occasions. |

3 . Artificial—intelligence systems like Grammarly, an automated grammar—checker, are trained with data. for instance, translation software is fed sentences translated by humans, Grammarly's training data involve a large number of standard error—free sentences and human—corrected sentences.
But grammar is the real magic of language, joining words into structures, joining those structures into sentences, and doing so in a way that maps onto meaning.
| A．Grammarly can seem to miss more errors than it marks. |
| B．One Grammarly feature that works fairly well is feeing analysis. |
| C．To correct such writing requires knowing what the writer intended. |
| D．Grammarly has some obvious strengths in understanding meaning or intentions. |
| E．Computers outpace humans at problems that can be solved with pure maths. |
| F．Developers also add certain rules to the patterns Grammarty has taught itself. |
| G．In this decisive structure—meaning connection, machines are no match for humans. |
4 . Babies are surrounded by human language, always listening and processing. Eventually, they put sounds together to produce a “Daddy” or a “Mama”. But what still confuses neuroscientists is exactly how the brain works to put it all together.
To figure it out, a team of researchers turned to a frequent stand-in (代替) for babies when it comes to language learning: the song-learning zebra finch. “We’ve known songbirds learn their song by first forming a memory of their father’s song or another adult’s song. Then they use that memory to guide their song learning,” said Neuroscientist Todd Roberts. “It’s been a long-term goal of the field to figure out how or where in the brain this memory is. This type of imitative learning that birds do is very similar to the type of learning that we engage in regularly—particularly when we’re young, we use it to guide our speech learning.”
Roberts and his team had a feeling that the interface (交叉区域) between sensory areas and motor areas in the brain was critical for this process, and they focused on a group of brain cells called the NIf.
“In order to prove that we could identify these circuits, we thought if we could implant a false memory.” First, they used a virus to cause the neurons (神经元) in the birds’ NIf to become sensitive to light. Then, using a tiny electrode as a flashlight, they activated (激活) the neurons. The length of each pulse of light corresponded with the amount of time the neurons would fire. And the birds’ brains interpreted that time period as the length of each note.
Soon enough, the birds began to practice the notes they had learned, even though they never really heard the sounds. Amazingly, the birds produced them in the correct social situations. The researchers say this is the first time anybody has found exactly a part of the brain necessary for generating the sorts of memories needed to copy sounds.
“This line of research is going to help us identify where in the brain we encode memories of relevant social experiences that we use to guide learning. We know that there are several neurodevelopmental disorders in people that have really far-reaching effects on this type of learning.”

5 . The vaccine (疫苗) news continues to seem very encouraging. Britain started its mass vaccination effort and the U.S. isn’t far behind.
But there is still one dark cloud hanging over the vaccines that many people don’t yet understand.
The vaccines will be much less effective at preventing death and illness in 2021 if they are introduced into a population where the coronavirus is still severe—as is now the case in the U.S.
A vaccine is like a fire hose (消防龙头). A vaccine that’s 95 percent effective, as Moderna’s and Pfizer’s versions appear to be, is a powerful fire hose. But the size of a fire is still a bigger determinant of how much destruction occurs.
At the current level of infection in the U.S. (about 200,000 confirmed new infections per day), a vaccine that is 95 percent effective—distributed at the expected pace—would still leave a terrible toll (伤亡人数) in the six months after it was introduced. Almost 10 million or so Americans would catch the virus, and more than 160,000 would die.
This is far worse than the toll in a different situation where the vaccine was only 50 percent effective but the U.S. had reduced the infection rate to its level in early September (about 35,000 new daily cases). In that case, the death toll in the next six months would be kept to about 60,000.
It’s worth pausing for a moment on this comparison. If the U.S. had maintained its infection rate from September and Moderna and Pfizer had announced this fall that their vaccines were only 50 percent effective, a lot of people would have panicked.
But the reality we have is actually worse.
How could this be? No vaccine can get rid of a pandemic immediately, just as .no fire hose can put out a forest fire. While the vaccine is being distributed, the virus continues to do damage.
There is one positive way to look at this: Measures that reduce the virus’s spread—like mask-wearing, social distancing and rapid-result testing—can still have great consequences. They can save more than 100,000 lives in coming months.

6 . Great work is work that makes a difference in people’s lives, writes David Sturt, Executive Vice President of the O.C. Tanner Institute, in his book Great Work: How to Make a Difference People Love. Sturt insists, however, that great work is not just for surgeons or special-needs educators or the founders of organizations trying to eliminate poverty in sub-Saharan Africa. The central theme of Great Work, according to Sturt, is that anyone can make a difference in any job. It’s not the nature of the job, but what you do with the job that counts. As proof, Sturt tells the story of a remarkable hospital cleaner named Moses.
In a building filled with doctors and nurses doing great life-saving work, Moses the cleaner makes a difference. Whenever he enters a room, especially a room with a sick child, he engages both patients and parents with his optimism and calm, introducing himself to the child and, Sturt writes, speaking “little comments about light and sunshine and making things clean.” He comments on any progress he sees day by day (“you’re sitting up today, that’s good.”) Moses is no doctor and doesn’t pretend to be, but he has witnessed hundreds of sick children recovering from painful surgery, and parents take comfort from his encouraging words. For Matt and Mindi, whose son McKay was born with only half of a heart, Moses became a close friend. As Sturt explains, “Moses took his innate (与生俱来的) talents (his sensitivity) and his practical wisdom (from years of hospital experience) and combined them into a powerful form of patient and family support that changed the critical-care experience for Mindi, Matt and little McKay.”
How do people like Moses do great work when so many people just work? That was the central question raised by Sturt and his team at the O.C. Tanner Institute, a consulting company specialized in employee recognition and rewards system.
O.C. Tanner launched an exhaustive Great Work study that included surveys to 200 senior executives, a further set of surveys to 1,000 managers and employees working on projects, an in-depth qualitative study of 1.7 million accounts of award-winning work (in the form of nominations (提名) for awards from corporations around the world), and one-on-one interviews with 200 difference makers. The results of the study revealed that those who do great work refuse to be defeated by the constraints of their jobs and are especially able to reframe their jobs: they don’t view their jobs as a list of tasks and responsibilities but see their jobs as opportunities to make a difference. No matter, as Moses so ably exemplifies (例证), what that job may be.

7 . Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.
One idea is that sleep helps us strengthen new memories.
Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day.
Now we have the most direct evidence yet that he is right.
If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.
Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size.
| A．We should also try to sleep well the night before. |
| B．It’s as if the brain is preserving its most important memories. |
| C．Similarly, when people go for a few days without sleeping, they get sick. |
| D．The processes take place to stop our brains becoming loaded with memories. |
| E．That’s why students do better in tests if they get a chance to sleep after learning. |
| F．“Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea. |
| G．Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice. |
8 . How you talk to yourself about events, experiences and people plays a large role in shaping how you interpret events. When you find yourself interpreting something in a negative way or only focusing on the bad aspect of the situation, look for ways to talk about the events in a more positive light.
When you find yourself worrying about things, look for an uplifting activity to pull yourself out of this negative mindset(心态)
The negativity bias (偏见) can have a powerful impact on your behavior, but being aware of it means you can take steps to adopt a more positive outlook on life. One of the best ways to combat negative bias is taking a more mindful approach involving being aware of your own tendency toward negativity and consciously elevating (使情绪高昂) happier thoughts to the forefront of awareness.
| A．It refers to seeing things in a new view. |
| B．It takes more for positive things to be remembered. |
| C．You probably don’t realize how often you say negative things. |
| D．Thinking repeatedly about the negative can result in a serious loss. |
| E．So when something great happens, take a moment to really focus on it. |
| F．This doesn’t mean ignoring potential dangers or wearing rose-colored glasses. |
| G．For example, you may find yourself mentally reviewing an unpleasant event or outcome. |
