1 . While scientists have many ideas, they are not certain why humans yawn(打哈欠). Still, there is one thing experts know—yawns seem to be contagious(传染)!
Have you ever caught a yawn from someone else? Most people have. In fact, a person is six times more likely to yawn after seeing someone else do so. Experts have done many studies into why yawns seem to pass from person to person. As a result, they have a few theories(理论) for the reason behind it.
One possible explanation has something to do with social mirroring, which is caused by mirror neurons(镜像神经元) in the brain. These mirror neurons help the brain notice useful behavior of others and then copy it. When one person sees another yawn, his mirror neurons observe the action and consider it to be beneficial. That may cause him to yawn, too.
Another popular theory is that yawns are contagious because of social relationships. Being social creatures, humans form friendships, families and live together in groups. That’s why many people mirror others, such as smiling when another person smiles. Yawning may be just another example of this. In fact, research has shown that one is most likely to catch yawns from another person if the two share a social relationship.
The answer could even be that yawns aren’t truly contagious at all. Instead, people yawn together simply because they’re in the same environment. Experts say many things may cause yawning, including temperature and time of day. Whatever the explanation is, experts do know that contagious yawns aren’t limited to humans. One study found that lions in South Africa also caught each other’s yawns.

2 . I came across some excellent tips on how to communicate better with others.
Pause(停顿)before replying to others.
Be honest.
Ask for feedback（反馈）from others. When it’s all said and done, one of the best ways you can learn to communicate more effectively is to ask for feedback. Take some time to speak to those who you communicate with frequently to find out how you can improve on your communication with them.

| B．Trust and hard work are valuable. |
| C．When you’re honest, communication becomes a lot easier. |
| D．I believe communication is key to living a good life. |
| E．It’s not always easy to ask for feedback, but it’s worth it! |
| F．You’ll be on the road to creating a better understanding with others. |
| G．Pause works wonders when it comes to communicating effectively with others. |
3 . Humans, by nature, have always lived in groups and social interaction is fundamental for every part of our health. Lack of it can lead to feelings of isolation and loneliness. A strong support network and solid community bonds promote our emotional and physical health, and are critical components of a balanced adult life. However, just as with many other aspects of our lives, there seems to be a limit to how large our personal networks can grow.
Back in 1992, a British scholar named Robin Dunbar came up with a hypothetical (假设的) number defining the maximum sum of meaningful human relationships a person can have. The number, which was later named after him, was discovered accidentally while he was studying the cleaning and brushing tendencies — a social behavior —of non-human primates (灵长类动物). Around that time, researchers had discovered that the large brain of these primates was a result of their socially complex societies. The relevance was that the larger the brain, the larger the animal's social group was likely to be. Scientists could then theoretically use an animal's brain size to calculate how many members could make up this group. Dunbar applied this theory to humans, and the resulting number was roughly 150.
Dunbar's Number, however, only refers to the limit of meaningful contacts within our social network. It does not account for other relationships. Human social relationships tend to have numerous layers, and extend outward from the individual in circles with the same centre. The innermost circle contains five people: our loved ones. The next circle holds of our good friends. The third circle is reserved for people we consider friends, and the fourth is where the limit of 150 can be found. Nowadays, with various forms of electronic communication, such as websites for social networking and microblogging people find it very convenient to create online communities to share information, ideas, personal messages, and other contents. Consequently, it is possible for a human to get into the fifth (500acquainitances) circle, an impressive breakthrough that was difficult to achieve in the past.

4 . Honesty is important. However, not everyone seems to think so. Lies and the hiding of truth are commonplace. But when examining the case for honesty, you realize it’s a better option. Here are the reasons why the value of honesty is beyond measure.
It is easier to understand.
You are more likely to get what you want. We often hide our true desires or preferences rather than speak out the truth. But when we are completely honest with ourselves and others, we encourage the right actions that lead to what we want.
It is better for your inner peace. Lying doesn’t come easy for most people. When you cheat others, it can feel like you are going against your values. Not only that, but as soon as you lie, you will live with the fear of that lie being discovered. That’s a mentally tiring thing.
| A．Telling the truth is simple. |
| B．It is the best way to prove your honesty. |
| C．Instead, it is so hard that no one can do it. |
| D．When we speak up, the other person is more likely to listen. |
| E．Honesty, though not always easy, doesn’t carry such burdens. |
| F．When you are clear in what you think, there’s no grey area for confusion. |
| G．Actually, it can be hard when you tell others what they don’t want to hear. |
5 . Having to deal with a rejection can be extremely difficult. But something that many people find even more difficult is to be the one who has to reject. Sometimes we accept out of politeness, in other cases because we simply don’t know in what possible way to say no.
Saying “no” in a proper way is quite difficult.
But due to the fact that we are no robots, it is not easy for us to make a decision based on whether we just like something or not.
Anytime you say “yes” when you know that you should have said “no”, no matter whether you rationalize (使合理化) it as a sign of friendship or kindness, in the end, it doesn’t change the fact that you have agreed to do something you absolutely do not want to do. That’s just because you don’t want to give others a reason to think negatively of you or believe that they will quit the friendship when you’re not doing everything they demand.
| A．If you don’t like it you just say “no” and reject it. |
| B．You can finally live the life the way you want it to. |
| C．As a result, we always end up with amounts of extra work. |
| D．It might help to see the situation just as emotionless as a robot. |
| E．Would you clearly express that you will not be able to do the extra work? |
| F．There will always be other factors that highly influence our decision-making process. |
| G．But actually a real friend will try to get his life straight without taking advantage of you. |
6 . How to Deal with Nosy (好管闲的) People
Nosy people are everywhere. They are just too much for us to tolerate. However, no matter what type of nosy people you meet, there are ways you can use to get out of the situation.
Respond. Do not react.
When someone starts asking personal questions one after another, you might get confused as to why. When you find yourself in this situation, remind yourself to slow down.
Answer them reasonably without showing too much.
One great way is to give a satisfactory answer without saying too many details. This way, you will satisfy their curiosity and keep your personal boundaries (界线) .
Sometimes, you just don’t feel like answering the other person’s questions. It could be because they have no business knowing the details. It could also be that they are rude. So, if someone asks you a personal question, you could politely decline to answer by saying, “Sorry, but I am not comfortable discussing my private matters like this.”
Show a lack of enthusiasm.
Your body language tells a lot about you. It tells other people whether you are interested in talking to them, whether you are having a good time and so on. So, if you want to communicate that you don’t appreciate them being nosy, you can do so with your body language. How do you do this? Easy! Just show a lack of enthusiasm.
| A．Avoid talking with them. |
| B．Politely decline to answer. |
| C．So, give yourself time to react. |
| D．There is no need to feel rushed at all! |
| E．Use this way when the other person is a loved one. |
| F．Give brief answers and don’t look them in the eye too much. |
| G．Follow the ones below and you will find it easy to deal with them. |
7 . Claire Wyatt, a 24-year-old British volunteer, led eight Cambodians living with disabilities on a 155-mile bike ride from Phnom Penh, the nation’s capital, to Siem Reap to raise money and deliver supplies to those in need in the coronavirus pandemic(新冠病毒大流行).
“Leading this trip was an incredibly special experience for me,” said Claire. “Not only was I encouraged by the determination of each and every rider, but also the team taught me every day not to focus on their disability.”
When she was first asked to lead the trip, Claire admitted, she was feeling nervous about her team traveling such a distance in just a few days because cycling with a disability can come with added physical and emotional challenges.
One team member named Dy, who lost an arm in an accident, biked using just one arm to balance. Another named Vulta could only pedal on one side due to polio(小儿麻痹). Despite all the difficulties, Claire realized quickly that she didn’t have to worry about her team. She saw them deal with rough area that she had seen abled cyclists give up on before.
The volunteers covered the distance in just four days, not only helping so many people across the country, but also overcoming huge difficulties to get there.
“The best thing about this ride is that the riders have all volunteered their time to do this. They are so enthusiastic about Cambodia and raising money for others in need,” said Claire. “The money raised will feed 99 families in Siem Reap.”
Claire recalled her favorite moment of the experience, when one of the cyclists pushed an exhausted teammate up a hill for 2 miles. “One moment that stood out for me was when Naret, our only female rider, was feeling tired,” she said. “Her fellow rider gently put his hand on her back and pushed her for 2 miles! They were encouraging each other to push through the tiredness.”

8 . Talking to someone on a train, bus, or subway can be risky yet exciting, as you never know when they’re going to get off. Starting a connection can be fun as the costs are fairly low and you can easily start and stop a conversation, or get off if things become awkward.
Make eye contact. Making brief eye contact can show the persons that you’re interested and help you judge whether they are interested in you. Glance at the persons and try to hold your gaze (注视) for just a second or two.
Smile at the persons. If you’ve successfully met their gaze, smile at them.
If you want to start a conversation with the persons, smiling is a great way to get somebody’s attention.
Approach the persons to start talking to them.
| A．Use open body language. |
| B．Mind your manners while talking. |
| C．Notice how they respond to your gaze. |
| D．Don’t worry because you can follow some tips that make you smile. |
| E．Once you’ve read that the persons are interested in chatting, make a move. |
| F．A small but sincere smile makes you appear interested, friendly and approachable. |
| G．Therefore, try to get someone’s attention and start a conversation by following the tips. |
9 . Suppose you become a leader in an organization. It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.
Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.
People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people’s wish of participation from an internal factor (e.g. “I volunteer because it’s important to me”) to an external factor (e.g. “I volunteer because I’m required to do so”). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.
Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.
Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in Hospital is an important part of who I am.” Consistent with the researchers’ expectations, they found a positive correlation(正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: “Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity....Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity”.

10 . Suppose you are out shopping and come across an acquaintance who starts telling you a story that seems to be dragging on and on. You want to seem interested, so you offer the occasional “Oh” or “I see”. To your surprise, though, this person angrily stops in their tracks and says, “Sorry if I’m boring you!”
Where did this come from? Clearly, your body language must have betrayed you. The idea that verbal (口头的) and nonverbal messages can conflict was the inspiration for a recently published study from Yale University’s Lueylle Armentano. As part of her study of communication in relationships, Armentano’s research also examined communication channels in people meeting for the first time.
To test the role of verbal-nonverbal mismatch on emotional communication, Armentano and her partner created experimental conditions to see what happens when someone asks for help from strangers. The research team created videotapes of a fellow Yale student expressing nervousness in his words, bodily gestures, or both. The bodily gestures included running his hands through his hair, grabbing his arm, and facially expressing uneasiness. The key question was whether the other participants, another 82 Yale students, would believe the student and provide the help he was requesting. They needed to give their responses.
Turning to the findings, those nonverbal cues (提示) of nervousness had a greater impact on helping behavior than the verbal cues. Surprisingly, helping behavior was the highest when verbal expressions of nervousness were low but nonverbal cues were high.
Recognizing that your body language can outweigh your words means that you need to be mindful of what your body is doing when you’re interacting with others. Generally, when someone is speaking to you, you want to look like you’re interested. Not only should you maintain eye contact, but you should keep your body still and face toward the other person. If you’re not trying to look interested, it may be more polite to say you have to be somewhere else.
