【推荐1】Do you have trouble trying to create the next big idea? Sometimes the answer isn’t to just force an idea out of your mind. Instead, you might want to try sitting back, relaxing and letting your mind wander. Yes, you heard that correctly. If you are in need of a new idea, try daydreaming.

Researchers from the university of California, Santa Barbara, found an association between daydreaming and creative problem-solving. Their study includes having participants first do an “unusual-use task”. They had to try to come up with as many different ways to use an object as they could.

Then, the participants chose to do one of the following four things before doing the “unusual-use task” again: complete a difficult task; complete an easy task; take a 12-minute break; or skip the 12-minute break and move right on to the task exercise again.

Surprisingly, the group that performed best was the one that completed the easy task. Many participants reported that they were daydreaming while performing the easy task. So the researchers believed that this daydreaming might have helped unlock their creativity.

But how could daydreaming help the brain come up with creative ways? The answer is something known as “unconscious thought”. Even when you are not actively working to solve a problem, it is still in the back of your mind. Your brain is still thinking about the problem, but in a much more subtle (不易察觉的) way.

When you daydream, your mind is allowed to think in ways it normally would not. Because it is free of control, it can create completely new and out-of-the-box ideas.

Great ideas never come easily, but that does not mean you always have to work hard to get them. Feel free to do what you want and let your mind wander.

【推荐2】You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.

“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd,” Gray told the BBC. “They are socially very interesting but often very awkward places.”

We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.

He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.

If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.

When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.

New entrants(新进入者) to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.

Why are we so awkward in lifts?

“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”

In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.

1. According to Gray, when people enter an elevator, they usually _____.

A．try to keep a distance from other people

B．look around or examine their phone

C．make eye contact with those in the elevator

D．turn around and greet one another

2. Which of the following describes how people usually stand when there are at least two people in an elevator?

C．put up with	D．judge

4. According to the article, people feel awkward in lifts because of _____.

【推荐1】According to researchers, money can buy happiness, but only if you spend it on someone else.

Spending as little as $5 a day on someone else could significantly bring you happiness, the team at the University of British Columbia and Harvard Business School found.

Their experiments on more than 630 Americans showed they were measurably (适度地) happier when they spent money on others — even if they thought spending the money on themselves would make them happier.

“We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia.

They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity (慈善机构).

“Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement.

Dunn’s team also surveyed (调查) 16 employees at a company in Boston before and after they received an annual profit-sharing bonus (奖金) of between $3,000 and $8,000.

“Employees who devoted more of their bonus to pro-social (有益社会的) spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor (预示) of their happiness than the size of the bonus itself,” they wrote in their report, published in the journal Science.

They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.

“These findings suggest that very minor alterations (改动) in spending allocations (分配) — as little as $5 — may be enough to produce real gains in happiness on a given day,” Dunn said.

【推荐2】Thailand’s capital Bangkok is both attractive and wonderful, a city of glass towers and concrete buildings crowded with nearly 10 million people. The ground beneath is spongy(松软多孔的) and moist. Imagine a brick resting on top of a birthday cake. That’s Bangkok-and it’s sinking into the Earth at an alarming rate.
Thailand’s disaster specialists have been warning of this coming disaster for years. One expert has said he’s worried about Bangkok resembling Atlantis. Another previously told Global post that the city will be under five feet of water by 2030. The latest estimates suggest that Bangkok is now sinking as fast as two centimeters per year in parts of the city. The predictions for 2100 are even more terrible. By then , Bangkok will be fully submerged and unlivable.
Like global warming, which will accelerate the city’s submersion by raising the sea leavel, Bangkok’s sinking problems are repeatedly _______But the monsoon season, currently underway, tends to bring this crisis to mind. A nasty storm can suddenly turn Bangkok’s streets into gushing streams. Sewers overflow, taxis move through dirty water and, occasionally, kids can pick up displaced fish.
Anond Snidvongs, director of the Southeast Asia Regional Research Center, predicts the city’s outskirts will be the first to go. Parts of the shoreline ebyong Bangkok are already liend with pumps that make noises and help to transform invading seawater. They don’t always work. During heavy rains, salt water flows in the streets of the city.
Bangkok is swallowed up a little more each day. Experts tend to offer two solutions. The first is to pu up a massive seawall that could cost nearly $3 billion-nearly 1 percent of Thailand’s current GDP. The second option is to give up entirely and move the capital to higher ground.
1. Why is Bangkok sinking into the earth?

A．Its buildings are too heavy.

B．It has an overlarge population.

C．Its underground is too loose.

D．It is resting on top of a lake.

2. What is the most likely meaning of the underlined phrase “shrugged off” in Paragraph 3?

A．ignored

B．valued

C．agreed

D．misunderstood

3. What information does Paragraph 4 express?

A．The optimism and wisdom shown by the city people.

B．The present serious situation Bangkok is faced with.

C．The weakness of the pumps to transform water.

D．The huge power produced by the surrounding seawater.

4. What’s the best title of the passage?

【推荐1】Last night’s meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothsclild, Emerald Valley’s mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city’s lights that it darkened the light of the meteors passing overhead.

“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”

Astronomers—scientists who study stars and planets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats frogs, snakes, etc. For example, outdoor lighting severely affects migrating birds. According to the International Dark-Sky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”

Countless more animals casualties result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase person’s chances of getting cancer.

Emerald Valley is only one community that is becoming aware of the negative effects of high pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

【推荐1】We often purchase food that's been mass-produced and that’s travelled many miles before it ends up on our plate. So for some, growing their own food is a better option — and it tastes good too!

From growing vegetables in little pots on your balcony to tending to a small plot of land, called allotments, there are many ways to produce home-grown food. Allotments are a typically British idea, and they give people with a small or no garden, a space to plant and care for fruit and vegetables. It can be backbreaking work digging, weeding and watering the soil, but the result is fresh and organically grown produce.

The recent COVID-19 pandemic lockdown means demand for allotments has seen a renaissance (复兴). Miriam from the University of Sheffield told the BBC that people with allotments have been spending a lot of their time on their plots, growing plenty of fresh fruit and veg — which, at times, have been challenging to source in supermarkets. She says “Coronavirus has... highlighted to people the fragility (脆弱) within our globalized food system. In a time of crisis, interest in self-sufficiency rises.”

But for those with limited space, a solution to grow your own veg lies closer to home-using pots. Once you can lay your hands on some compost (堆肥), you can plant seeds. Sheila Brand lives in a third-floor flat. She has managed to grow tomatoes and aubergines and is already harvesting raspberries. She said excitedly: “Oh it’s got a new leaf!”

As well as the benefits of saving money and enjoying tasty food, gardener Mark says “growing your own from a balcony or window ledge not only improves your wellbeing and immediate environment, you can actually grow a lot of veg.” So, maybe it’s time for us all to get planting and develop our green fingers!

1. What is the characteristic of allotments?

A．Mass-produced.	B．Organically grown.
C．Typically American.	D．Only growing vegetables.

2. What is the reason for a renewed interest in allotments?

A．The outbreak of coronavirus.	B．The challenge from supermarkets.
C．Globalized food system.	D．The rise of self-confidence.

3. Sheila Brand is mentioned to      .

A．attract more readers to read the passage	B．offer a clear idea of the text structure
C．call on more people to stay at home	D．serve as an example of problem solving

4. What can we infer from the last paragraph?

A．It is very economical to buy food from the supermarket.

B．There are many advantages of growing your own food.

C．Planting can make our green fingers green and tender.

D．If you want to have delicious food, you must grow on your own.

【推荐3】The dodo is among the most famous extinct creatures, and_______ for human-caused extinction events. Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton(骨架) from a single bird takes advantage of modern 3-D laser scanning(扫描) technology to open a new window into the life of this famous extinct bird.
The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, "the 3-D laser surface scans we made of the fragile dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge."
A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. "Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was," said Juilan Hume, of the Natural History Museum UK, a co-author on the study.
The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the scans provide an insight into how the flightless dodo may have developed its giant size, and how it walked and lived in its forest home. According to Kenneth Rijsdijk, a biologist from University of Amsterdam, “the skull of the dodo is so large and its mouth so strong that it is easy to understand that the earliest naturalists thought it was related to sharks and other birds of prey（猛禽）, rather than the pigeon family.”
