The new sixth-grade teacher, Sava, is like most teachers in schools. This morning, she is calling the attendance list and asking the students in the back of the room to be quiet. Sava(smile) at the students and looks happy. Sava doesn't really look different from other teachers,she is. Sava is a robot. She is remote controlled a person through a camera inside the robot. Although Sava is not ready to be a real teacher, the children enjoy her visits.
Wilbur and Orille Wright are brothers famous for inventing the first aeroplane. Their interest in flight(start) on the day when their father brought home a toy helicopter for them. It was made of paper and wood. The boys played with it until it broke, and then made their own(replace) it. When they were older, they owned a bicycle shop where they started producing and selling their own bikes. This provided them with the money to pay for their experiments in flight. Eventually, they built their (fly) machine.
Because deaf people can't hear, they have special ways of communicating. For example, they can learn to understandsomeone is saying by looking at the mouth of the speaker. This(call) lipreading. Also, speaking is very difficult for the deaf, because they can't hear(they) own voices. However, it is possible with special training. According to many deaf people all around the world, the most (practice) and popular way of communicating is with sign language.
“Come on, Cindy!" Darcy sounded so impatient, “We'll be late for class."
“Darcy, I can't find my1." I dropped my book bag to dig through my coat pockets. “My money was in it."
“Someone took it." Darcy said. As usual, she was quick to point away from the2side of things. “Oh. I'm sure I just misplaced it." I hoped. Even though we were best friends, Darcy and I were just so3.
We rushed into class. Darcy4the news about the theft. By last period in gym class, I was5of having to say over and over again, “I'm sure I just left it at home."
After gym, we went into the locker room. I was changing6I heard a gasp from Darcy. I looked at her and found her face was white with7. There, at her feet, was my wallet.
“It fell out of her locker!" Darcy pointed at Juanita, a “new girl" in our class. “She8it."
Everyone began to9Juanita at once.
“Darcy caught her red-handed."
“Report her!"
I looked over at Juanita. She picked up the wallet and held it out to me. Her hands were10. “I found it in the parking lot. I was going to give it to you."
Darcy spit the words “I'm so sure!" at her.
“Really, it's true." Juanita's eyes began to fill with tears.
I11for my wallet. I didn't know what to think,12when I looked over at Darcy, her attitude made me sick inside. I looked at Juanita. She was scared but looked13. I knew I held her14in my hands.
“I am so glad you found it," I smiled. “Thanks, Juanita."
The15around us broke.
“Good thing she found it," everyone but Darcy16.
“If there is any money left in your wallet."
“Not now. Darcy!"
“You are so naive!"
It wasn't until others left there that I opened my wallet.
“It's all here." I couldn't help but feel17. A folded piece of paper fluttered from my wallet. I opened it to see what it was.
“She just didn't have time to18it yet."
“Darcy, maybe you spend too much time19people."
Darcy grabbed the note, read it and threw it back at me. “Whatever!" she said and stomped off. I knew that something had20between us.
I read the note again.
Cindy,
I found your wallet in the parking lot. Hope nothing is missing.
Juanita
P.S. My phone number is 55-3218. Maybe you could call me sometime.
And I did.
Slowly, so slowly that we never even noticed how it happened, our family stopped talking to each other. Our own worlds opened up to us through the computer or the cell phone or the CD player.
Family Night was born when Mom called us for dinner. Jessica and I came and sat down. Dad loaded his plate and started to rise from the table.
“Where are you going?” Mom questioned.
“To the living room. I have some work,” Dad replied as he hurried away. Mom's face got tight, but she said nothing. About two minutes later, my cell phone buzzed. Jessica kept her earphones on during most of the meal. Mom was clearly upset.
Family Night started the next week. Mom established three rules: no phones, no music, and no leaving the table. Everyone would eat together and play a game together “like a real family.”
All seemed to be going according to Mom's plan until the first buzz of a cell phone. After dinner, we had been playing the board game for only ten minutes when another cell phone let out a shrill scream. This time the phone belonged to my father.
“Work's calling. I have to answer,” he whispered as he hurried out of the room.
Mom sighed, but she forced a smile and encouraged us to continue with the game. We kept playing through every interruption afterwards: the beeping of Jessica's phone, the buzz of another text message from Darnell, the soothing voice announcing the arrival of an e-mail on Dad's computer. When the game was over, Mom released us to our rooms.
That first Family Night was not a success, but Mom soldiered on. Every Monday evening we silenced our electronics and gathered around the table; and each time, setting aside our technological toys became a little easier. The next two months my father would be taking business trips. We wouldn't be able to have Family Night every Monday.
To my surprise I realized that I would miss those few hours each week when the house was filled with my family's laughter and conversation. I was also glad to know that when we really wanted to, we could silence the electronic buzz and just be a family again.

Alanna Mallon is a Cambridge City Councilor.
Each year in November, I receive a flurry of emails and texts from friends who want to volunteer with their families on Thanksgiving as a way to give back. I also field phone calls from organizations who want to donate to local programs that provide Thanksgiving meals.
However, as an official who still works in the nonprofit sector, I also feel deeply anxious because I know the other 51 weeks of the year, these critical programs that provide food access to residents in need are starving for both volunteers and donations. Hunger is a year round problem, and each week volunteers are the necessary part to ensure that programs are able to serve the community.
At Food For Free, we rely on about 100 volunteers per week, and each of those volunteers is extremely important to providing fresh, healthy food to people in the Greater Boston area who need it. School children who take backpacks of food home on Fridays, community college students who rely on our Family Meals program to thrive in class, elderly and disabled residents who receive twice monthly deliveries of food to their doors through our Home Delivery program, — they all rely on us ensuring enough volunteers show up to do the work.
These volunteers don't show up in your social media feeds, they don't win awards and no one writes about them in the local newspapers. But they are heroes. And you can be too.
If everyone made a promise to volunteer once a month, or even once a quarter, I know that we could reduce some of the anxiety these organizations feel, as a more reliable volunteer network allows them to focus on helping people, not filling volunteer slots.
Here is a list of a few organizations who are doing critical work in Cambridge to address food insecurity. Offer your time to an organization, they will be deeply grateful—and I am going to bet that you will feel pretty good about yourself too.

Many of us listen to music while we work, thinking that it will help us to concentrate on the task at hand. And in fact, recent research has found that music can have beneficial effects on creativity. When it comes to other areas of performance, however, the impact of background music is more complicated.
The idea that listening to music when working is beneficial to output probably has its roots in the so-called “Mozart effect”. Put simply, this is the finding that spatial rotation performance(空间旋转能力) is increased immediately after listening to the music of Mozart, compared to no sound at all.
How sound affects performance has been the topic of research for over 40 years, and is observed through a phenomenon called the irrelevant sound effect. To study irrelevant sound effect, participants in the research are asked to complete a simple task which requires them to recall a series of numbers or letters in the exact order in which they saw them. The tricky thing is being able to do this while ignoring any background noise.
Two key characteristics of the irrelevant sound effect are required for its observation. First, the task must require the person to use their rehearsal abilities(复述能力), and second, the sound must contain acoustical variation(声学变化). Where the sound does not vary much acoustically, the performance of the task is much closer to that observed in quiet conditions.
The irrelevant sound effect itself comes from attempting to process two sources of ordered information at the same time—one from the task and one from the sound. Unfortunately, only the former is required to successfully perform the recall task, and the effort in ensuring that irrelevant order information from the sound is not processed actually hinders(阻碍) this ability.
A similar conflict is also seen when reading while in the presence of lyrical music. In this situation, the two sources of words—from the task and the sound—are in conflict. The cost is poorer performance of the task in the presence of music with lyrics.
What this all means is that whether having music playing in the background helps or hinders performance depends on the task and on the type of music, and only understanding this relationship will help people maximize their productivity levels.
According to official government figures, there are more than twice as many kangaroos as people in Australia, and many Australians consider them pests(有害动物). Landholding farmers say that the country's estimated 50 million kangaroos damage their crops and compete with livestock for scarce resources. Australia's insurance industry says that kangaroos are involved in more than 80 percent of the 20,000-plus vehicle-animal collisions reported each year. In the country's underpopulated region, the common belief is that kangaroo numbers have swollen to “plague proportions."
In the absence of traditional hunters, the thinking goes, killing kangaroos is critical to balancing the ecology and boosting the rural economy. A government-sanctioned(政府认可的) industry, based on the commercial harvest of kangaroo meat and hides, exported $29 million in products in 2017 and supports about 4,000 jobs. Today meat, hides, and leather from kangaroos have been exported to 56 countries. Global brands such as Nike, Puma, and Adidas buy strong, supple “k-leather" to make athletic gear. And kangaroo meat is finding its way into more and more grocery stores.
Advocates point out that low-fat, high-protein kangaroo meat comes from an animal more environmentally friendly than greenhouse gas-emitting sheep and cattle. John Kelly, former executive director of the Kangaroo Industry Association of Australia, says, “Harvesting our food and fibers from animals adapted to Australia's fragile rangelands is extremely wise and sustainable. Many ecologists will tell you that there is no more humane way of producing red meat."
Opponents(反对者) of the industry call the killing inhumane, unsustainable, and unnecessary. Population estimates are highly debatable, they say, but “plague proportions" are biologically implausible. Little kangaroos grow slowly, and many die, so kangaroo populations can expand by only 10 to 15 percent a year, and then only under the best of circumstances. Dwayne Bannon-Harrison, a member of the Yuin people of New South Wales, says the idea that kangaroos are destroying the country is laughable. “They've been walking this land a lot longer than people have," he says. “How could something that's been here for thousands of years be 'destroying' the country? I don't understand the logic in that."
Can Australians' conflicting attitudes toward kangaroos be reconciled(和解)? George Wilson says that if kangaroos were privately owned, then graziers(放牧人)—working independently or through wildlife conservancies—would protect the animals, treating them as possessions. They could feed them, lease them, breed them and charge hunter a fee for access. “If you want to conserve something," Wilson says, “you have to give it a value. Animals that are considered pests don't have value."
Privatization could also help reduce grazing pressures. If kangaroos were more valuable than cattle or sheep, farmers would keep less live-stock, which could be good for the environment. Under this scheme, landholders would work with the kangaroo industry on branding, marketing and quality control. The government's role would be oversight and regulation.
Empathy is the ability to imagine what it must be like in someone else's situation. It is an essential part of what it means to be human, to the extent that we are suspicious of anyone who does not show empathy in their behavior.
We read novels, watch television and go to the theatre, and part of our enjoyment comes from understanding the dilemma faced by the characters because we know how we would feel if we were in the same situation.
One study has shown animals displaying empathy towards other animals and towards humans. Creatures from across the animal kingdom such as bees and whales, as well as domestic pets, display behavior that suggests they cooperate with and protect each other.
In another study, psychiatrist Jules Masserman and his team conducted an experiment with monkeys in which the monkeys pulled one of two chains that released food. One chain simply released the food, while another gave an electric shock to a second monkey. The first monkey stopped pulling the chain that delivered the shock.This empathetic behavior was observed in a number of monkeys.
The origin of empathy is probably the need for the young of all animal species to be cared for. They communicate this requirement by crying for attention and to show pain. Both human and non-human young were more likely to survive if their parents reacted positively to their needs. People and animals alike are social beings and are more likely to work together.If we help others, we are also helping ourselves and so empathy is sensible and realistic.
We don't always display empathy, however. Just as animals react aggressively to unknown creatures from their own or other species, humans tend to regard people they don't know with suspicion.Our unwillingness to trust anyone unfamiliar is as natural to us as our empathy towards those we know and love.
A. To feel empathy is not restricted to real life.
B. You can empathize with someone without feeling sympathy for them.
C. This fear of strangers will, we believe, protect us from personal danger.
D. It seemed to be willing to go hungry rather than see a fellow animal suffer.
E. However, it seems that in fact empathy may not be a quality unique to humans.
F. Empathy plays a role in that as it allows us to understand our fellow humans better.
G. It's certainly difficult to understand an animal's intention behind an emphatic response.
