The eighth chapter is exceedingly brief, and relates that Gibbons, the amateur naturalist of the district,     1     lying out on the spacious open downs without a soul     2     a couple of miles of him, as he thought, and almost dozing, heard close to him the sound as of a man coughing, sneezing, and     3     swearing savagely to himself; and looking, beheld nothing. Yet the voice was indisputable. It continued to swear with that breadth and variety     4     distinguishes the swearing of a cultivated man. It grew to a climax, diminished again, and died     5     in the distance, going     6     it seemed to him in the direction of Adderdean. It lifted to a spasmodic sneeze and ended. Gibbons had heard nothing of the morning’s occurrences,     7     the phenomenon was so striking and disturbing that his philosophical tranquillity vanished; he got up hastily, and hurried     8     the steepness of the hill towards the village, as fast as he could go.

Why do people read negative Internet comments and do other things that will obviously be painful'？Because humans have an inherent need to    1     uncertainty，according to a recent study in Psychological Science. The new research reveals that the need to know is so strong that people will seek to satisfy their curiosity even when it is clear the answer will hurt.

In a    2     of four experiments，behavioral scientists at the University of Chicago and the Wisconsin School of Business tested students' willingness to express themselves to unpleasant stimuli in an effort to satisfy curiosity. For one    3    ，each participant was shown a pile of pens that the researcher claimed were from a previous experiment The twist. Half of the pens would    4     an electric shock when clicked.

Twenty-seven students were told which pens were electrified；another twenty-seven were told only that some were electrified.When left alone in the room，the students who did not know which ones would shock them clicked more pens and incurred（遭受）more shocks than the students who knew what would happen.Subsequent experiments reproduced this effect with other stimuli，such as the sound of fingernails on a chalkboard and photographs of     5     insects.

The drive to discover is deeply    6    in humans，much the same as the basic drives for food or shelter，says Christopher Hsee of the University of Chicago. Curiosity is often considered a good instinct---it can lead to new scientific advances，for instance---but sometimes such    7     can backfire.The insight that curiosity can drive you to do self-     8     things is a profound one.

Unhealthy curiosity is possible to     9     , however. In a final experiment，participants who were encouraged to predict how they would feel after viewing an unpleasant picture were less likely to choose to see such an image.These results suggest that imagining the outcome of following through on one's curiosity ahead of time can help    10    whether it is worth the endeavor.“ Thinking about long-term consequences is key to reducing the possible negative effects of curiosity，" Hsee says. In other words，don't read online comments.

In recent weeks, many parents have realized the difficult truth about school this fall because of COVID-19. Hoping for a better     1    , parents around U.S. have started organizing “pandemic (流行病) pods”, or home schooling pods, for the fall, in which groups of 3 to 10 students learn together in homes under the guidance of the children’s parents or a hired teacher.

For parents who can organize and     2     them, pods seem like an easy choice. “I don’t believe that the online courses for that age group are     3    . Kids at this age really need that multimodal sensory learning (多模式感官学习).” one parent said.

These pods could     4     families with a schooling choice that feels safe—yet also allows kids to have fun and build social skills. However, it also has unavoidable shortcomings.

Depending on how the pods are set up, they may offer parents break. But given that pods can be     5    , complicated to organize and self-selecting, it is possible that they are most popular among wealthy families, experts say, and may     6     educational inequality.

Another     7     about pods is that families may not know how to minimize Covid risks. Pods shouldn’t have more than five kids     8    , said Saskia Popescu, an infection prevention expert. When you add together the teacher and all of the kids’ family members, a seemingly small pod ends up including dozens of people, and the more people in it, the greater the     9     for coronavirus exposure (接触). Furthermore, families in learning pods shouldn’t socialize with people outside the pod unless they wear masks and     10     socially distant, Dr. Popescu said. Pods should have clear rules on wearing masks and washing hands.

A huge milestone has just been reached in the field of artificial intelligence: AlphaGo, a program developed by Google’s DeepMind unit, has defeated legendary Go player Lee Se-dol in the first of five historic matches being held in Seoul, South Korea. Lee     1     after about three and a half hours, with 28 minutes and 28 seconds remaining on his clock. The series is the first time a professional 9-dan Go player has taken on a computer, and Lee is     2     for a $1 million prize.

“I was very surprised,”said Lee after the match.“I didn’t expect to lose. But I didn’t think AlphaGo would play the game in such a perfect manner.”DeepMind founder Demis Hassabis expressed“huge     3     for Lee Se-dol and his amazing skills.”calling the game“hugely exciting”and“very tense.”Team lead David Silver said it was an“amazing game of Go that really pushed AlphaGo to its     4    .”

Go is an ancient Chinese board game that has long been considered one of the great     5    faced by AI. While computer programs ow best the world’s leading human players of games like checkers and chess, the high level of intuition and     6    required by Go has made it tough for computers to crack. DeepMind’s AlphaGo program is the most     7    effort yet, using a complex system of deep neural networks and machine learning; it beat European champion Fan Hui last year, but Lee Se-dol is another     8     rival entirely.

“I don’t regret accepting this challenge,”said Lee.“I am in shock, I admit that, but what’s done is done. I enjoyed this game and look forward to the next. I think I failed on the opening layout so if I do a better job on the opening aspect I think I will be able to increase my     9     of winning.”Lee was surprised both by how strong AlphaGo’s opening was, and by some     10    moves.

Nine times out of ten, students complain to their Physical Education teachers about being out in the hot sun, running around for no reason. Perhaps in lower level education, children see it as a     1     of escaping the classroom, but as they grow older, it’s simply looked upon as a huge waste of time and energy.

However, engaging in acts of physical activity from a young age is very important for both the mental and physical health of a child; the habits learnt in youth tend to continue into adulthood, thus having an effect on the prevalence of obesity and     2     illnesses in society. Physical activity has been     3     with an increased life expectancy in adults so its importance is obvious, but its value for children sometimes needs to be     4    . It is never too early to start teaching a child    5     behavior and habits; however, in middle childhood (ages 6-10) children tend to be in a stage of development where they think very literally and will absorb everything you teach, do and say.It is during this stage of development that they are most likely to be taught healthy eating habits, develop exercise programs and have an interest in     6     sports.

Physical activity is one of the most important things we all can and should do to keep our body in healthy     7    . There are many health conditions that don’t require a pill to be swallowed on a daily basis but ca be helped with a tiny amount of time invested in exercising. Physical activity is     8     for both mental and physical health. It has also been considered a tool for boosting our social life.

People who see exercise as a total waste of time should understand that exercise is essential to life because it not only prevents us from being susceptible to illness, but it also teaches us how to be disciplined in the     9     that we have complete control over our body and its outcome. Today we live in an environment where we get more unhealthy foods and beverages for a lesser cost, which in     10     promotes greater consumption, and unhealthier children and adults.

If the package looks pretty, people will buy just about anything. So says an advertising executive in New York, and he has proved his point by selling boxes of rubbish for the price of an expensive bottle of wine.
Justin Gignac, 26, has sold almost 900     1    presented plastic boxes of rubbish from the street of Big Apple at between ＄50 and ＄100 each. Buyers from 19 countries have paid for the souvenirs(纪念品). The idea has been so successful that he is thinking of promoting it around the world.
It all began when Mr. Gignac was at a summer workshop, “We had a discussion about the importance of     2    ,” he recalls. “Someone said packaging was unimportant. I disagreed. The only way to prove it was by selling something nobody would ever want.”
He searches the streets of Manhattan and typical     3    include broken glass, subway tickets, Starbucks cups and used     4    forks. “Special editions” are offered at a high price. He charged ＄100 for rubbish from the opening day of the New York Yankees’ stadium.
Mr Gignac denies     5    his customers for fools: “They know what they’re getting. They appreciate the fact that they’re taking something nobody would want and finding beauty in it.”
Some     6    customers include people who used to live in the city and want a down-to-earth souvenir. He claims he has even sold to art collectors.
Realizing that the concept appears to be a real money-maker, Mr Gignac has     7    a company and is employing his girlfriend as vice president. He     8    to discuss his profit margins: “It’s actually quite a lot of effort putting them together—but yes, garbage is free.”
Mr Gignac is considering more varieties of souvenirs. He maintains that he has signed     9    with people interested in similar projects from as far as Berlin and London.
