A Vacation with My Mother

I had an interesting childhood. It was filled with surprises and amusements, all because of my mother---loving, sweet, yet absent-minded and forgetful. One strange family trip we took when I was eleven tells a lot about her.

My two sets of grandparents lived in Colorado and North Dakota, and my parents decided to spend a few weeks driving to those states and seeing all the sights along the way. As the first day of our trip approached, David, my eight-year-old brother, and I unwillingly said good-bye to all of our friends. Who knew if we’d ever see them again? Finally, the moment of our departure arrived, and we loaded suitcases, books, games, camping equipment, and a tent into the car and bravely drove off. We bravely drove off again two hours later after we’d returned home to get the purse and traveler’s checks Mom had forgotten.

David and I were always a little nervous when using gas station bathrooms if Mom was driving while Dad slept: “You stand outside the door and play lookout(放哨) while I go, and I’ll stand outside the door and play lookout while you go.” I had terrible pictures in my mind: “Honey, where are the kids?” “What?! Oh, Gosh…I thought they were being awfully quiet.” We were never actually left behind in a strange city, but we weren’t about to take any chances.

On the fourth or fifth night, we had trouble finding a hotel with a vacancy. After driving in vain for some time, Mom suddenly got a great idea: Why didn’t we find a house with a likely-looking backyard and ask if we could set up tent there? David and I became nervous. To our great relief, Dad turned down the idea. Mom never could understand our objections(反对). If a strange family showed up on her front doorstep, Mom would have been delighted. She thinks everyone in the world is as nice as she is. We finally found a vacancy in the next town.

5 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.

To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.

So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

6 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

What’s the problem? It’s possible that we all have compromised conversational intelligence. It’s more likely that none of us start a conversation because it’s awkward and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s an invaluable social practice that results in big benefits.

Dismissing small talk as unimportant is easy, but we can’t forget that deep relationships wouldn’t

even exist if it weren’t for casual conversation. Small talk is the grease(润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. ＂Almost every great love story and each big business deal begins with small talk,＂ he explains. ＂The key to successful small talk is learning how to connect with others, not just communicate with them.＂

In a 2014 study, Elizabeth Dunn, associate professor of psychology at UBC, invited people on their way into a coffee shop. One group was asked to seek out an interaction(互动) with its waiter; the other, to speak only when necessary. The results showed that those who chatted with their server reported significantly higher positive feelings and a better coffee shop experience. ＂It’s not that talking to the waiter is better than talking to your husband,＂ says Dunn. ＂But interactions with peripheral(边缘的) members of our social network matter for our well-being also.＂

Dunn believes that people who reach out to strangers feel a significantly greater sense of belonging, a bond with others. Carducci believes developing such a sense of belonging starts with small talk. ＂Small talk is the basis of good manners,＂ he says.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

On a bright, warm July afternoon, Mac Hollan, a primary school teacher, was cycling from his home to Alaska with his friends. One of his friends had stopped to make a bicycle repair, but they had encouraged Mac to carry on, and they would catch up with him soon. As Mac pedaled (骑行) along alone, he thought fondly of his wife and two young daughters at home. He hoped to show them this beautiful place someday.

Then Mac heard quick and loud breathing behind him. “Man, that's a big dog!” he thought. But when he looked to the side, he saw instantly that it wasn’t a dog at all, but a wolf, quickly catching up with him.

Mac’s heart jumped. He found out his can of hear spray. With one hand on the bars, he fired the spray at the wolf. A bright red cloud enveloped the animal, and to Mac's relief, it fell back, shaking its head. But a minute later, it was by his side again. Then it attacked the back of Mac's bike, tearing open his tent bag. He fired at the wolf a second time, and again, it fell back only to quickly restart the chase（追赶）。

Mac was pedaling hard now. He waved and yelled at passing cars but was careful not to show down. He saw a steep uphill climb before him. He knew that   once he hit the hill, he’d be easy caught up and the wolf’s teeth would be tearing into his flesh.

At this moment, Paul and Beeky were driving their car on their way to Alaska. They didn’t think much of it when they saw two cyclists repairing their bike on the side of the road. A bit later, they spotted what they, too, assumed was a dog running alongside a man on a bike. As they got closer, they realized that the dog was a wolf. Mac heard a large vehicle behind him. He pulled in front of it as the wolf was catching up fast, just a dozen yards away now.

9 . Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.     1    

Now we have the most direct evidence yet that he is right.     4    The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.

If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information — our brains may have smaller room for new experiences.

Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size.     5     “You keep what matters,” Tononi says.

10 . Hollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics（控制论）, put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”

A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.

The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.

Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.
