【推荐1】One day when some government officials were rebuilding a barn (谷仓), they found a mouse hole in a corner and used smoke to force the mice inside the hole to come out. A while later they really saw mice running out, one after another. Then, everyone thought that all the mice had escaped. But just as they began to clean up, they saw two mice squeezing (挤) out at the mouth of the hole. With some efforts, the mice finally got out. However, it was strange that after they came out of the hole, they did not run away immediately. Instead, one chased after the other near the mouth of the hole. It seemed that one was trying to bite the tail of the other.

Everyone was puzzled, so they stepped nearer to take a look. They realized that one of the mice was blind and could not see anything, and the other was trying to allow the blind mouse to bite on his tail so that he could pull the blind one with him to escape.

After seeing what happened, everyone was speechless and lost in thought. During the meal time, the group of people sat down in a circle and started to talk about what happened to the two mice.

One serious American official said, “I think the relationship between those two mice was that of king and guard.” The others thought for a while and said, “That was why!”

A clever French said, “I think the relationship between those two mice was that of husband and wife.” Again the others thought for a while, and all felt it made sense.

A Japanese said, “I think the relationship between those two mice was that of mother and son.” Once again the others thought for a while, and felt this was more reasonable. So they expressed agreement another time.

At that moment, one Chinese asked, “Why did those two mice have to have a certain relationship?”

Suddenly, the group looked back at the Chinese and remained speechless. The American official, the French and the Japanese who had spoken earlier all lowered their heads in shame, and did not dare to answer.

In fact, true love is not built on friendship, loyalty or blood relationship. Instead, it is built on no relationship.

【推荐2】A psychologist walked around a room while teaching stress management to audience. As she raised a glass of water, everyone expected they’d be asked the “half or half full” question. Instead, with a smile on her asked, “        ”

Answers come out from 8 oz(盎司) to20oz.

She replied, “The real weigh doesn’t matter. It depends on how long I hold it. If I hold it for a minute, it not a problem. If I hold it for an hour, I’ll have an ache in my arm. If I hold it for a day, my arm will feel numb and paralyzed. In each case, the weigh of the glass doesn’t change, but the longer I hold it, the heavier it becomes.

She continued, “The stresses and worries in life are like the glass of water. Think about them for a while and nothing happens. Think about them a bit longer and they begin to hurt. And if you think about them all day long, you will feel numb —unable to do anything.”

It’s important to remember to let go of your stresses. As early in the evening as you can, put all your burdens down. Don’t carry them through the evening and into the night. Remember to put the glass down!

【推荐3】Friday was "Chatty Bus day", an experiment aimed at getting people to talk to each other on public transport. This is not an idea that would appeal to those who commute in the rush hour, because there is a smaller distance within which it's just as uncomfortable to talk. Elbow(肘) room is a precondition for sociability. It is no coincidence that the first truly personal music player, the Sony Walkman, was invented in Japan where the commuter trains are literally crowded with people.

We will also not talk to strangers who are physically too far away, of course. No one wants to shout their small talk. Only on country buses or similar unhurried and uncrowded forms of public transport can people reach out to their neighbors, confident that they are doing so from a position of strength and autonomy.

For all these drawbacks, the idea of talking to strangers is still a good one, and the promotion of sociability is good for society. Although it does seem to be a general rule that people are friendlier the fewer there are of them and more hostile and indifferent as cities get more crowded, there are still considerable cultural variations. And there is evidence that friendlier places are also healthier, and their inhabitants happier.

It is true that the apparent loneliness of many people on public transport is a false impression.

Many will be caught up with conversations with distant friends on their phones; some will be talking to the people in books. Some may be in willed solitude with their headphones. But there are always people who would be interested in an unexpected conversation with a stranger. This need not go on for too long.

It is not large and possibly life-changing conversations that are what most people in loneliness miss most. What they really need is not deep thought but superficiality. The kind of conversation that you could have with anyone reminds you that you yourself might be anyone. It is a release from the prison of the self, which is where lonely people serve their sentences, uncertain whether they ever can be paroled(假释). Friendship may be too rare a gift to hope for, but sometimes the kindest thing to say is also the simplest: "Don't be a stranger"-and sometimes that's also enough.

1. According to Paragraph 1, why the first Walkman appeared in Japan partly?

A．its corporate culture

B．its overcrowded public transport

【推荐1】The full stop, which comes from Greek punctuation (标点符号), is usually used to express the end of a sentence but now it frightens young people when used in social media communication as a sign of anger.

According to experts, youngsters used to communicating electronically break up their thoughts by sending each one as a separate message, rather than using a full stop, which they use only to signal they are annoyed. Some have said the full stop is redundant when used in texting because the message is ended just by sending it. “If you send a text message without a full stop, it’s already obvious that you’ve concluded the message.”

Owen McArdle from Cambridge University told the newspaper: “I’m not sure I agree about emails. I guess it depends how formal they are. But full stops are very much the exception in youngsters’ instant messages, and have a new role in expressing anger.”

In 2015, a study from Binghamton University in New York suggested that people who finish messages with full stops are considered insincere. The study involved 126 undergraduates and the researchers found that text messages ending in the most final of punctuation marks-eg “lol.”, “let’s go to Nando’s.”-were considered being less sincere. Unusually, texts ending in an exclamation point-“lmao!”, “what body part even is that? I hope it’s your arm!” -are thought heartfelt.

Research leader Celia Klin said at the time: “When speaking, people easily convey social and emotional information with eye gaze, facial expressions, tone of voice, pauses and so on. People obviously can’t use these when they are texting. Thus, it makes sense that texters rely on what they have available to them-special signs, deliberate misspellings that imitate (模仿) speech sounds and, according to our data, punctuation.”

1. What is the most likely reason for a young person to use a full stop when texting?

A．To show insincerity.	B．To conclude the message.
C．To express his anger.	D．To suggest it’s a formal message.

2. Which of the following is similar to the underlined word “redundant” in paragraph2?

A．Irregular.

B．Incorrect.

C．Illogical.

D．Unnecessary.

3. What can be inferred from the last two paragraphs?

A．The full stop is not as important as before.

B．The exclamation point is often used to show sincerity.

C．Punctuation is always associated with an angry tone of voice.

D．Deliberate misspellings are frequently used to convey emotions.

4. What could be the best title of the passage?

A．A new punctuation.	B．A new role of the full stop.
C．A new generation with annoyance.	D．A new way of texting in communication.

【推荐2】There’s more evidence that what’s good for your heart is good for your head. A new study shows that people who run, swim or do other moderate intensity(强度)exercise have brains that look, on average, 10 years younger than the brains of couch potatoes.

“Our study showed that for older people, getting moderate intensity exercise may be protective, helping them keep their brains work better, ”said Dr. Clinton Wright of the University of Miami, who led the study. But it’s not necessarily easy. Walking, golf, bowling and yoga didn’t count, and people need to start before they begin showing memory loss, Wright’s team reported in the journal Neurology.

The study of nearly 900 people who exercise regularly showed that 90 percent fell into the low-intensity group. These people are part of a larger group taking part in a bigger study called Northern Manhattan Study. They were asked how long and how often they exercised during the past two weeks. Five years later, they were tested for memory and thinking skills and got a brain MRI. Seven years after that, they took the memory and thinking tests again. The 10 percent who said they took part in moderate intensity exercise scored better on the tests. These included running, climbing, swimming, riding bicycles and so on．

“We found that those with moderate exercise had higher scores and slower decline than inactive patients when comparing the results,” the study team wrote.

Many studies have shown that exercise may not prevent Alzheimer’s but may delay it. The findings fit in with a study that found two years of exercising, eating healthier food and brain training can promote people’s memory function.

1. What do we know about the study？

A．It makes people’s heart better than their heads.

B．Running, Swimming and Yoga are regarded as moderate intensity.

C．More than 900 people participated in the Northern Manhattan Study.

D．Most people surveyed took low-intensity exercise.

2. How did the study team draw the conclusion?

A．By making a comparison.

B．By analyzing the existing data.

C．By recording people’s exercise.

D．By giving examples.

3. What can be inferred from the last paragraph?

A．Exercise can prevent people suffering Alzheimer’s disease.

B．Brain training will certainly strengthen people’s memory.

C．Exercise can put off the start of memory decline.

D．The findings fit in with the study of healthy food.

4. What’s the best title for this passage?

A．How to keep mentally healthy

B．Moderate intensity exercise keeps your brain younger

C．Steps to promote your brain performance

D．How to prevent the Alzheimer’s disease

【推荐3】Due to the increasing number of violence acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can assure their safety and well-being，although teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons in charge of the safety of the students．
The main reason for violence acts are the films and cartoons that fill the children’s time．They want to do everything．they watch on TV and never think at the consequences，and they may hurt a classmate or a teacher．
On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results．
When a teacher has to watch 30 students in class he can’t probably see what each of them is doing，how he is writing，or if he understands the explanations．At home the teacher can explain in details everything the child doesn’t understand as many times as he considers proper．
And many times，the child grows fond of the teacher at home，who becomes his best friend，and who helps him whenever he needs someone to talk to．       
However, the best solution would be a mixture between the education received at school and that at home，because school makes children communicate and socialize．Keeping a child at home for fear that there might be something bad happening to him only makes the child’s character weak and prevents him from knowing what real life is．Staying in a crystal ball only does harm to the child．
All in all，schools have been created to help children，not to harm them，so it’s best to keep children in these special places，where they learn，laugh，have fun and make new friends．

【推荐2】(The New York Times, Oct.7) The 2019 Nobel Prize in physiology(生理学) or medicine was jointly awarded to three scientists — William G. Kaelin Jr., Peter J. Ratcliffe and Gregg L. Semenza — for their work on how cells sense and adapt to oxygen availability. The Nobel Assembly announced the prize at the Karolinska Institute in Stockholm on Monday.

Their work established the genetic mechanisms(机制) that allow cells to respond to changes in oxygen levels. The findings have implications(启示) for treating a variety of diseases.

Why did they win?

“Oxygen is the lifeblood of living organisms(生物体),” said Dr. George Daley, dean of Harvard Medical School. “Without oxygen, cells can’t survive.” But too much or too little oxygen can be deadly. The three researchers tried to answer this question: How do cells regulate their responses?

The investigators uncovered detailed genetic responses to changing oxygen levels that allow cells in the bodies of humans and other animals to sense and respond to fluctuations(波动), increasing and decreasing how much oxygen they receive.

Why is the work important?

The discoveries reveal the cellular mechanisms that control such things as adaptation to high altitudes and how cancer cells manage to hijack(攫取) oxygen. Randall Johnson, a member of the Nobel Assembly, described the work as a “textbook discovery” and said it would be something students would start learning at the most basic levels of biology education.

“This is a basic aspect of how a cell works, and I think from that standpoint alone it’s a very exciting thing.” Johnson said.

The research also has implications for treating various diseases in which oxygen is in short supply — including anemia, heart attacks and strokes — as well as for treatment of cancers that are fed by and seek out oxygen.

1. This research has won the Nobel Prize mainly because ____________.

A．there was no research of this kind in the past

B．oxygen is the lifeblood of living things

C．it has uncovered how cells sense and respond to changes in oxygen levels

D．various diseases will be cured with the help of the findings of the research

2. We can learn from the passage that _____________.

A．The Nobel Prize was awarded to a physiologist on Monday in Sweden.

B．Cancer cells manage to hijack oxygen and need oxygen to develop.

C．The more oxygen there is in blood, the healthier a living body will be.

D．The genetic mechanisms have been found that allow oxygen to adapt to cells.

3. Which of the following can best explain the underlined word in the text?

【推荐3】At the start of every working week, millions of people around the world get ready for something they do endlessly, joylessly and badly ： a meeting

It was awful before the pandemic (疫情), when research showed there were an average of 55 million meetings daily in the US alone. I fear to think what the figures look like now that Covid-19 and remote working have started the age of the continuous meeting.

It wouldn't be a problem if all meetings did what they were supposed to do and helped busy people make good decisions about important matters. But the evidence suggests otherwise. Studies over the past 15 years have shown about 70 percent of workers have rated their meetings poor or unproductive, writes US professor, Steven Rogelberg, in his 2019 book The Surprising Science of Meetings.

“The root of the rotten meeting is simple," says Madeleine de Hauke, a meeting coach and teacher. “We spend our lives in meetings, but there's very little investment (投入)into helping people run them effectively," she told me last week.

A meeting coach might say that, but I think Ms de Hauke is correct. Running a meeting well takes skills. At a minimum, people need to know in advance why they are meeting； what they are supposed to achieve ； who really needs to be there and how they should contribute. Yet meeting leaders are expected to learn all these on the job.

I thought the pandemic had made things worse. But Ms de Hauke makes a convincing argument that Zoom calls merely strengthen what was going on before. If a meeting was productive and cheerful before, it is probably better now. If it was wasteful and annoying, it is likely to be worse.

Still, a bad meeting is like a virus. By failing to produce good decisions it often requires another meeting to be held, then another and another. Luckily, there is no need for a vaccine (疫苗), just a bit more care and preparation, and an understanding that there is no shame in being taught how to lead a meeting well.

1. What does the passage focus on?

A．Why people hate meetings.

B．How Covid-19 affects meetings.

C．Recommending experienced meeting coaches.

D．Suggesting developing the skills of meeting running.

2. According to the author, what's the problem of bad meetings?

A．Meetings are poor and short.

B．Meetings are dull and fruitless.

C．Meetings make people less interested in work.

D．Meetings cause people to make wrong decisions.

3. How can a meeting leader run a good meeting?

A．Invite people to attend the meeting in advance.

B．Invest much money to run meetings successfully.

C．Set clear goals and make preparations for the meeting.

D．Make everybody present at the meeting learn some skills.

4. How does the author develop the last paragraph?

A．By comparison.	B．By classification.

【推荐1】Florence, a 17-year-old senior student in High School, was busy ,composing(编曲)a song. She plans to release an album(唱片)with three other music lovers whom she met at the 2016 Campus Singing Competition. Edward, 18, is another one of the four students to make their own album. Actually, he was the one who came up with this fun idea in the first place.

"Everyone loves music. Being a good way to express our feelings and emotions, music can tell something about who we are and our experience of the world. We hope we can use our music to touch our peers(同龄人)." Edward said.

The album includes 15 songs across three themes - love, campus life, and youth, with pop and electronic music styles. The inspiration for the songs came from the students' lives. Take the song Sea of Tranquility for example - it was written by Edward during a flight back to Chengdu after he took part in the China High School Biology Olympiad in summer. "The sky is clear and the ground looks small from the plane. This scene makes me feel calm and peaceful." Edward explained.

The songs were created one by one with the efforts of the four writers. But a challenge soon appeared. The students found that they didn't have enough money to produce the album. So to cut down their budget, they used an iPad and headphones to record the songs in an empty classroom on the weekend.

Apart from reducing their cost, they also tried to raise money through crowd funding on the internet. They raised more than 7,000 dollars before the album was released in October. "Thanks to all the supporters, we'll keep working on our own music." Edward said.

1. Why did they make the album?

A．To earn money.	B．To be famous.
C．To influence young people.	D．To make friends.

2. Which of the following best describes Edward and his music team?

A．Upset.	B．Stubborn.

【推荐3】With coronavirus outbreaks at different stages around the world, in many countries lockdowns are being carefully eased off while urging citizens to keep on practicing the social distancing rules. Singapore is trying a new way of carrying it out—a robot dog.

The government has arranged Spot, a yellow and black robotic dog made by Boston Dynamics Company, at one local park. The same robot has been previously seen dancing to hit song “Uptown Funk.”However, 2020 is an extremely difficult year and the company is trying to assist the national coronavirus-control effort. In turn, the job has been handed over to Spot.

The four-legged robot dog patrols(巡查) the park and broadcasts a pre-recorded message to encourage visitors to observe safe distancing measures. As it walks around the park, the dog says in a female voice, “Let's keep Singapore healthy. For your own safety and for those around you, please stand at least one meter apart. Thank you.”

Spot is one of the world's most advanced robots and unlike wheeled robots, it is capable of going pretty much anywhere a dog can go and can walk up to three miles per hour over different areas, making it ideal for operation in public parks and gardens. Furthermore, it is remotely controlled and has cameras with 360-degree vision and analytic tools to scan the surroundings and help officials estimate the number of people gathering in the park.

For now, the pilot project is currently set to run in a limited trial for two weeks at one park during off-peak(非高峰)hours. But if all goes well, authorities will consider expanding the program to improve enforcement(强制)of social distance throughout on Singapore

Spot is also being used in other ways during the public health crisis beyond just patrolling a park. The government says it's also using Spot in another capacity- at a local isolation facility where the robot helps bring medicine to patients.

1. What do we know about Spot in the passage?

A．It's a dog-like robot that can speak.	B．It’s a robot that can sing a popular song.
C．It’s a wheeled robot that can walk anywhere.	D．It's a robot newly invented during the pandemic.

2. How does Spot carry out its duty in the park?

A．It enforces people to follow the rules.	B．It politely reminds people to keep apart.
C．It works day and night to patrol the park.	D．It warns visitors against littering anywhere.
