1 . Simon Griffiths is the founder of Who Gives A Crap, a company that has ________ the toilet paper industry.

Inspired by his experience in developing countries, Simon ________ to sell goods to make a difference. But what should he sell? One day, Simon walked into the bathroom and a good idea ________ him: he could sell toilet paper and donated half profits to help fund organizations building toilets. Who Gives A Crap was born.

Too often, people buy products that ________ to their taste but without clever packaging, so his ________ was to create something that ________ quality and aesthetics (美学), so that people would want to put it in their bathroom.

It was not beyond their ________ that their goods sold well. Their donation to WaterAid Australia has grown from the initial 2, 00 AUD to 5.85 million AUD, they becoming its largest ________ .

4 . Two years ago, my son sat me down for a talk. “Mom, it’s time,” he said. “Hear me out: It’s time we got actual TV. And you need an iPhone.”

This funny conversation two years ago marked a change in our relationship. Perhaps for the first time, I began to really listen to John’s opinion about our home technology. Since his reasoning was sound and his suggestions were within budget, I took his advice and was pleasantly surprised with the results.

I’d known for a while that my son understands technology better than I do. On airplanes, he grabbed my phone to put it in airplane mode. He wired the speakers in our house. After something was stolen from our front yard, he picked out, set up, and now monitors our security camera. When my computer died, I took him shopping with me.

He has a busy social life, with skateboarding, basketball, and online gaming. I see our time together reducing and our shared interests shrinking. That’s why I jumped at the chance when a friend mentioned writing technology reviews. When I presented the idea to my teen, he immediately accepted.

It’s changed our relationship in surprising ways. Where he used to get annoyed quickly at my technical ignorance, he’s learned to be more patient and explain things to me in a way that I can convey to an equally unknowing audience. The parent- child dynamic is not only changed; it’s even slightly reversed (颠倒). He’s leading me. I’m asking him for help and advice.

My son has risen to the occasion. He’s taking it seriously, and to watch him mature in this way is an honor. As someone not much of a reader, he now searches instruction booklets. Without any prompting, he’s even emailed and called — yes, made an actual phone call — to customer service or tech support when products weren’t working as expected.

I never imagined being a tech reviewer, but it’s proved to be a valuable way to learn from, work with, and enjoy time with my teen.

7 . People may form inaccurate impressions about us from our social media posts, finds new Cornell University research that is the first to examine perceptions of our personalities based on online posts.

An analysis of online status updates found great difference between how viewers saw the authors across a range of personality traits (个人特质), and the authors’ self-perceptions.

Viewers rated the Internet users as having lower self-esteem and being more self-revealing than the users rated themselves. Status updates containing photos, videos or links in addition to text facilitated more accurate assessments than those with just text, the researchers found.

Overall, the study illustrates the dynamic process by which a cyber audience tries to make sense of who we are from isolated fragments (碎片) of shared information, jointly constructing our digital identity.

“The impression people form about us on social media based on what we post can differ from the way we view ourselves.” said Qi Wang, professor of psychology and director of the Culture & Cognition Lab. “A mismatch between who we are and how people perceive us could influence our ability to feel connected online and the benefits of engaging in social media interaction.”

The Cornell researchers believe their study is the first to investigate audience perceptions of social media users through their posts. On platforms, users often share fragmentary personal narratives while interacting with “friends” they may know only a little or sometimes not at all.

Wang said the findings could help developers design interfaces (界面) that allow people to express themselves most authentically.

“If people’s view of us is very different from who we actually are, or how we would like to be perceived,” Wang said, “it could harm our social life and well-being.”

8 . I am asked repeatedly why anyone would want to keep an “ugly” building or a building that is dirty and clearly in need of work. I guess you could say we preservationists (文物保护者) look at buildings through a different angle — an angle that can see the swan in the ugly duck, the story in the simple lines, and the book behind the cover.

The Queen Emma Building is remembered by many as one of the ugliest buildings in town. Yet the angle from which a preservationist views the building is that it is uniquely constructed with an artistical sun shield to block the sunlight, a decorative wall designers used concrete bricks to form. Unfortunately, it was removed in 2011, making the building one of many contemporary buildings in town.

Other times, when a beautiful site is replaced by a “horrible” building, people hate it and can’t get over their anger, even when that “horrible” building becomes an important part of our story. This is particularly true in San Francisco with many Victorian buildings, which are many. preservationists’ favorite. Yes, it was a tragedy that many Victorian buildings. got torn down several decades ago, but those losses also tell another important story. It tells the story of the 1950s and 1960s when there was hope for a more equal society with inexpensive housing for the working class. Should that history be wiped from our memories?

Preservation is not just about keeping pretty, well-kept buildings, but about holding on to parts of our history — not just the history of huge events, but the story of how everyone used to go to a certain corner market. Our history cannot be told only in buildings that meet someone’s criteria of beauty; sometimes our history is painful, but no less important.

9 . Theophilus Tetteh is an African contemporary artist from Ghana. He _________ himself in the study of graphic design and painting at school while experimenting with _________ themes, ranging from politics to entertainment.

The art market as such is not yet _________ in Ghana. The country doesn’t even have a national gallery to _________ and promote Ghanaian art works.

The platform __________ welcomes artists who don’t have resources or promotional opportunities.

Tetteh says, “The world can be a better place if young artists are guided on their way without any form of disregard, but with __________ of the senior.”

10 . You probably know that sunshine affects your mental and physical health. New research shows it may also affect your appetite-but only if you’re male.

That finding surprised Carmit Levy, who had been studying how ultraviolet-B (UV-B) rays affect the skin of mice. The sun’s UV-B rays are the main cause of sunburns and skin changes that can lead to cancer. Levy exposed mice to these rays for a few weeks. The dose was so weak that it didn’t cause any redness. But Levy noticed changes in the animals’ fa t tissue. Part of the mice also became heavier.

Levy ordered new mice to look into these unexpected changes. The new group included a mix of males and females. She found that UV-B exposure enhanced the appetite of male mice — but not females’. The males also worked harder to get at food that was difficult to reach. Something was really motivating them to eat more.

She wondered whether sunlight might have a similar effect on people. To find it out, she gathered volunteers for two studies. Both suggested that men and women may respond differently to UV-B. But the number of volunteers in these tests was too small to be persuasive.

Fortunately, Levy’s colleague Andrews had access to data from almost 3,000 people. They’d all participated in Israel’s first nutrition survey, some 20 years before. These data showed that 1,330 of the surveyed men consumed more food in summer months. From March to September, they tended to down about 2,188 daily calories. They averaged only about 1, 875 calories from October to February. The 1,661 women in this study consumed about 1,500 calories per day all year long.

Longer days in summer give males of many species more time to hunt and provide for their families. Consuming more food would give them the energy to do just that. In human evolution, UV-B might have motivated our male ancestors to hunt more to help their community survive.
