Humans are quick judgment machines. With the seemingly reliable 1 , we form firm and far-reaching opinions of others. Science is 2 those judgments are also often correct although they can sometimes be 3 .
Actually, it turns out that we're not 4 to believe so firmly what someone's gesture or face 5 . It is found that these clues really can predict our personalities. Take a study, for example. When the scientists 6 data on walking and personality of more than 15,000 7 of all ages, strong patterns appeared: a fast walker is more likely to be outgoing. 8 , slow walkers are hesitant. Now we know personality indeed has an influence on walking.
But what about the 9 , you might ask We all tend to naturally slow down as we get older, but not everyone slows down at the same 10 . Personality affected not only walking speed, but also how the way of walking became different overtime. Those who were outgoing had a slower 11 in walking speed.

I'm not allowed to touch the moon rocks. This is the lab where the Johnson Space Center 1 the original samples that the Apollo astronauts 2 to the earth decades ago. As I stare at the rocks through glass, Charis, my tour guide, says in a 3 voice: No touching the moon rocks.
Before 4 this clean room, I remove all my jewelry. My guide and I cover our shoes with blue-paper booties and step into full-body jumpsuits. We then 5 gloves and a hair cover. Finally, we spend a full minute standing in an air shower, under a steady light wind 6 from ceiling to floor to 7 us of any fine dust.
Inside the clean room, the rocks are kept in 8 , pressurized containers.
Only five sample processors in the world get to 9 handle these precious stones. They preserve and prepare the samples for studies. To pick up an Apollo rock, they must use special tools, following pretty strict 10 about touching samples. All the 11 is to protect the 382 kilograms of rocks lifted from the moon.
"One big 12 belief is that the Apollo samples aren't being studied any more and that they only tell us about the moon," says Charis. "Neither of those is true."
Keeping priceless samples away from curious 13 allowed scientists to make one of the most surprising lunar 14 of the last 50 years: The moon is wet. Those samples are still offering fresh details about how the 15 — and the entire solar system— formed and developed.

One of the greatest mysteries in biology—how the monarch butterfly travels thousands of kilometers on its yearly migration—has just been solved.
Monarch butterflies use the sun to 1 their body clocks and make their journeys, according to US scientists.
No other butterfly in the world migrates like orange and black monarchs of North America. Each autumn, thousands travel up to 3,300 km to spend winter in the mountains of Mexico. There are so many that they almost 2 the sky. And you can hear their wings 3 .
It usually takes the butterflies two 4 to reach Mexico. After five months of stay, they head back up north in the spring. But not one butterfly 5 the whole round trip. They lay eggs along the way and die.
Three 6 of butterflies will live and die during the spring journey alone. The fourth and final offspring (后代) of the year are born in early autumn and will reach the 7 . But it hardly gets to rest before starting the 8 journey south to Mexico.
Past studies have shown the insects use the 9 as a compass to show them the way. But experts were unsure how the butterflies change their 10 as the sun moves in the sky.
This new study now shows the insects use a body "circadian" clock as part of their sun compass. In laboratory tests, monarch butterflies were 11 to fly in the right direction under normal daylight hours. But those flying in 24-hour light headed 12 towards the sun. They no longer had any 13 of time.
Steven Report, who led the research, said, "We have shown the 14 for the circadian clock for monarch butterfly migration. When the clock is interrupted, monarchs are 15 to fly towards Mexico. "

Some fifteen years ago, when smartphone apps were new and few truly understood their potentials, retailers（零售商）barely knew that consumers could browse in stores while comparing prices and 1 from other item providers through certain apps before 2 making the purchase online. Ten years ago, brick-and-mortar（实体店）retailers had to acknowledge that showrooming existed and appeared to be a threat. That's the year when retailers were up in arms as online giant Amazon released an "evil" promotion that encouraged consumers to visit 3 stores and use Amazon's Price Check app at the same time. Any purchase completed through the app was given 4 discounts, which significantly stimulated sales and 5 many shop owners to the edge of bankruptcy.
From the point on, retailers began launching strategies to combat showrooming including releasing 6 items for sale so that no reference prices from other sources are available for comparison.
"Media have reported showrooming as a big threat to physical stores, "says Casey Carl, a retailer. "However, less 7 is the fact that it is also the greatest opportunity for us." Retailers need to accept that the act of showrooming is not illegal and any sensible buyer tends to 8 prices. As there's nothing you can do about it, you might as well offer conveniences like in-store internet access to 9 these consumers. With caring services combined with acceptable prices, the store might actually improve the likelihood for consumers to close the deal 10 .
And a showrooming study indicates that it's wise for retailers to limit the item price to at most 5 dollars higher than what online stores charge. After all, for the majority of consumers, getting the absolute lowest price is not their 11 . Many of them, instead, are willing to pay 12 in exchange for favourable shopping experiences, such as the pleasant store atmosphere, agreeable staff attitudes or even the merry music played, with reasonable price 13 , of course.
Besides, adopting a strategy of 14 channels is also essential. With many sale channels under control, retailers are sure to have access to the lowest price possible for an item. Therefore, when a customer pulls out a mobile device in store, retailers can be spared the 15 that was unavoidable for them some ten years ago.

Are you a digital hoarder
Most people are familiar with hoarding(囤积) and the psychological issues associated with it. Hoarding leads to messy homes and difficulty ____1____ with items that you don't use and don't even need. But hoarding can also occur in the digital world.
Digital hoarding, also known as e-hoarding, is too much acquisition and ____2____ to delete electronic material no longer valuable to the user. Most computer users save digital files to some extent, and that's expected. With digital hoarding, however, the act of saving the files becomes an uncontrollable ____3____. Digital hoarders may collect emails, photos, articles, podcasts, or any type of computer files they believe they may want to revisit in the future, and ultimately, in most cases, they ___4____ get to actually use it or listen to it or read it.
Digital hoarding also occurs when someone is too ____5____ to the data even to consider getting rid of it. This can include chats and photos of an old partner, ____6____ sent by a long-lost friend, or even screenshots collected several years ago.
Researchers have ____7____ digital hoarders into 4 different types, according to their characteristics. "Collectors" are organized, ____8___ and in control of their data. "Accidental hoarders", also called "____9____ or disorganized hoarders", don't intentionally save unnecessary data. They just don't know how to organize it. "The hoarders by instruction" keep data on behalf of their company (even when they could delete much of it). Finally, "anxious hoarders" have strong emotional ____10____ to their data — and are worried about deleting it.
The problem has only gotten worse since we have more ___11___ to digital storage than ever. In addition, cloud storage makes it incredibly easy to purchase more storage as needed. With ____12____ cloud space, it's logical when network users don't think twice about saving files.
However, studies found that digital hoarders experience increased levels of stress and now researchers are observing that the negative consequences of digital hoarding may be similar to those of ____13____ hoarding. ____14____, it's important to set time aside to have a good clear-out, in the same way we do in the physical world. By organizing and ____15____ useless files in a regular way, people with this problem can ease some of their distress and clear their own mind as well.

What would happen if a human brain was connected to a powerful computer That is what Kevin Warwick, a professor at the University of Reading, U. K., 1 to find out. "I want to have a go at exploring what it means to 2 ," he says.
Soon he will have an 3 A glass tube will be placed around a group of nerves in his arm. Inside the tube there will be tiny computer circuits. These will 4 messages being sent to the brain and send them to a computer.
"Pain provides a clear electronic signal on the nervous system as it moves from its 5 of origin to the brain. We want to find out what happens if that signal is sent to the computer and then played back again. Will I feel the 6 pain " says Kevin Warwick.
It is not just about 7 . The human nervous system sends a wide variety of other messages to the brain, which could have many different 8 . The computer could provide the eyes for a blind person.

Leslie Morissette's son, Graham, was six years old when he was diagnosed with leukemia (白血病). Throughout Graham's treatment in the hospital, he connected with everyone he met, from 1 patients to younger children.

He gave me the energies and the 4 to fight together with him." In 1997, when he was eight years old, Graham passed away.
Inspired by how Graham lived his life caring about others, Morissette founded the 5 Grahamtastic Connection in his late son's honor. The organization provides free technology—including computers, tablets and robots—for children 6 against cancer or other serious illnesses.
One of the major goals of Morissette's work is to 7 kids to their classrooms. This helps them continue their education despite frequent hospitalization (住院治疗) and days 8 from school.

If a child is unable to attend school, he can 11 turn on the tablet or laptop and 12 the robot. Children can walk up and down the school paths, and go to lunch with their friends. But the real magic happens 13 classes. The robots enable them to walk down the hallway with their friends, talking about their weekends, their favorite foods and other things. It's a really great 14 that gives children the feeling of control, when their world is maybe out of control.

Curious, Puri did some research and discovered a shocking 4 : Africa’s forest elephant population had 5 by about 62 percent between 2002 and 2011. Years later, the numbers continued to drop. Puri, a wildlife lover, wanted to do something to help protect the species and others still 6 by poaching.

Rockets were probably invented by accident about 2000 years ago. The Chinese had a form of gunpowder which was put in bamboo tubes and thrown into fires to make 1 during festivals. Perhaps some of the tubes jumped out of the fire instead of exploding in it. The Chinese discovered that the gunpowder 2 from the tube could lift it into the air. The idea of the rocket was 3 .
The first 4 use of rockets was in 1232. The Song Dynasty was at war with the Mongols. During the 5 of Kaifeng, the Song army 6 “arrows of flying fire”. The tubes were 7 to a long stick which helped keep the rocket moving in a straight direction. 8 the Mongols learned how to make rockets themselves and it is possible that they 9 them to Europe. Between the 13th and 15th century there were many rocket 10 in England, France and Italy. They were used for military purposes. One Italian scientist even invented a rocket which could travel over the surface of water and hit a(an) 11 ship.
Not everybody wanted to use rockets in battles. Wan Hu, a Chinese government official, invented a 12 chair. He fixed two big kites to the chair, and 47 rockets to the kites. The rockets were lit, there was a huge explosion and 13 of thick smoke. When the smoke 14 Wan Hu and his chair had disappeared, no one knows what happened.

History has not yet 1 what we will definitively call the post millennial cohort (2000年后出生的人) that now 2 more than 60 million people in the U.S. These kids and 3 with no concept of life 4 the Internet have so far been called the App Generation and Generation Z. They’ve been referred to as Homelanders, having grown up under the ghost of terrorism. They’ve also been 5 the Plurals for their historic diversity, as well as the Founders, at least by MTV.
Whatever we 6 naming them, marketer and academies are turning their attention to this group, which has billions in 7 and is already shaping the culture. This generation is growing up “totally and utterly connected” says California State University psychologist Larry Rosen. Experts like Rosen have concerns about these kids’ Google-inspired expectations that everything be 8 . They worry about their inability to 9 even five seconds of boredom. And they worry about the demands that come with 10 several identities online, from Facebook to Twitter to Snapchat. “There’s so much pressure on young people, who are still 11 their identities, to present this crystallized, idealized identity online,” says the University of Washington’s Katie Davis.
Historian Neil Howe sees 12 with the Silent Generation, the spoilt risk-avoiding “nice” generation of kids who grew up during the Great Depression and World-War II, although some marked differences are found. Today’s youths are also coming of age among geopolitical trouble and fears about the economy, he says, 13 schools emphasize an intense far-reaching sensitivity to other kids. He suspects this 14 will be known for being well behaved and perhaps boring the culture by playing it safe. “There are typical examples that occur repeatedly,” Howe says, "even if they go by different 15 .”
