1 . History has not yet _______ what we will definitively call the postmillennial cohort (2000年后出生的人) that now _______ more than 60 million people in the U.S. These kids and _______ with no concept of life _______ 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 terorism. They’ve also been _______ the Plurals, for their historic diversity, as well as the Founders, at least by MTV.

Whatever we _______ naming them, marketers and academies are turning their attention to this group, which has billions in _______ 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 _______. They worry about their inability to _______ even five seconds of boredom. And they worry about the demands that come with ________ several identities online, from Facebook to Twitter to Snapchat. “There’s so much pressure on young people, who are still ________ their identities, to present this crystallized, idealized identity online,” says the University of Washington’s Katie Davis.

Historian Neil Howe sees ________ 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, ________ schools emphasize an intense far-reaching sensitivity to other kids. He suspects this ________ 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 ________.”

Museum Craze Involves More Teenagers

More museums are here waiting for you! China’s capital, Beijing, is going to open another batch (一批) of museums this year. The building of a new branch of the Palace Museum, one of the world’s most visited tourist attractions, kicked off as well.

As the museum craze has grown stronger in the past few years, teenagers in China have become more involved in exploring museums, where they can immerse (沉浸) themselves in modern technology as well as culture from the past. According to Educator magazine, visits by teenagers to museums each year increased from 220 million to 290 million in the past 5 years. Among the increasing numbers of museum visitors, many of them were teenagers accompanied by their families, reported Guangming Daily earlier this month.

To draw younger visitors, many museums are creating more offline activities for the purpose of spreading Chinese culture. They include artifact making, night visits, secret adventures, treasure evaluation, and some interesting courses. At the China Hangzhou Arts & Crafts Museum, for example, teenagers gathered around to make paper umbrellas during the Spring Festival holiday. With white gloves on and little spades in their hands, visitors in Henan province got to experience the daily work of archaeologists (考古学家). Apart from the activities, some museums even open branches especially designed for teenagers. A hall called Popular Agricultural Science for Young Visitors is a special branch launched by China Agricultural Museum. It is an exhibition hall that combines both visual and audio technology to involve teenagers in agriculture. Besides these offline approaches, a number of museums have also created official websites for teenagers, the Palace Museum in particular. Online visitors may go on an exciting adventure on the website in the style of a comic book.

4 . Artificial intelligence (AI) has amazing potential to change the world, and we’ve only just begun to scratch the surface. As AI matures and people move further away from distinct programming and monitoring of systems, unidentified bias (偏见) might make decisions continue for a long time that cause _______ harm for individuals and society. This bias might _______ input data or even the algorithms (算法) themselves.

All too often, data sets are incomplete and the sample represented in the data set does not _______ the population that the AI model is making predictions about — this is known as coverage bias. Some other types of bias related to input data include sampling bias, where data is not collected randomly from the target group, and participation bias, where users from certain groups _______ surveys at different rates than users from other groups. Still, another more challenging bias to identify is confirmation bias that occurs when a decision maker or analyst has a strong _______ belief or experience that affects their ability to consider alternatives. This could lead one to more strongly _______ data that confirms a preexisting belief.

Bias resulting from AI algorithms themselves, or algorithmic bias, is equally _______. One example of algorithmic bias is implicit bias or unconscious bias, where data scientists _______ make associations or assumptions based on their mental models and memories that affect data modeling decisions. Implicit bias can _______ how data is collected and classified, or how systems are designed and developed. As machines learn, their conclusions and decisions affect people. Ethical (道德的) AI must understand these impacts and create governance and testing methods to ________ mistakes and inaccuracies.

To create ethical AI, companies need to put the ________ of the individual at the center of data innovation. This means thinking about ________ rights as human rights and developing a comprehensive approach to data, including how we use AI.

Having ________ data practices for AI means having good AI governance. This governance not only focuses on data and analytics but also understands the impacts of any given analysis and makes sure it’s ________ and accurate. Good AI governance includes data responsibility as well as a commitment to transparency (透明性).

None of this will be easy, but true innovation never is. By coming together and working on the problem of bias now, before it becomes a(n) ________ force, businesses can help bring out the best AI has to offer the world.

5 . Looking on the Bright Side with Moon Worship

According to Cheshire psychic Claire Stone, a growing number of women are looking to the moon to increase their health, power and wealth. Daily Mail reporter Samantha Brick recently ______ a full moon ceremony hosted by Ms. Stone in a field near Hale. She joined a group of females dressed in white as they stood in a circle holding hands.

“There is drumming and chanting,” wrote Ms. Brick, “then ______ as each woman engraves her hopes and ambitions for the coming month on a white or silver candle.” They were told to ______ what they wanted to attract into their lives. “We ‘see’ it coming true in our minds,” said Ms. Stone. “The ______ is amplified by the energy of the moon and those in the circle.”

Ms. Stone said that wishing on the moon helped her move into her ______ home, a £l.4 million farmhouse, which she shares with her husband and two daughters.

Ms. Stone was initially attracted to complementary sources of ______ as a teenager suffering from anxiety. “I started looking for something to help make me happier,” she said. “I first joined a couple of local groups where women would ______ once a month on the full moon when I was in my 20s. It seemed like a natural and ______ thing to do.” The paper commented: “Claire, who drives a black Mercedes GLE coupe, was so ______ by her early experiences of moon circles that she decided to hold her own monthly ceremonies outside her home.

They have been a(n) ______ success: at various times more than 3,000 women have come along. Her circles —priced at £22.00 for a two-hour session—______ for up to 100 women at a time online, and 50 at a time in person. Several famous and powerful women have announced their interest in moon worship. Friends actor Jennifer Aniston is said to ______ moon circles where women sit and share their experiences and dreams. Lady Carole Bamford, described in the press as a “billionaire eco entrepreneur” explains on her website. “Our bodies are made up of 70 per cent water, so it’s no wonder that the moon, which controls the ______, has the power to affect us all in different ways as well.”

The report ended with veterinary nurse Victoria Twist, who ______ the moon for her return to full health after spinal surgery. Ms. Twist is also convinced that ______ attending moon circles, she was also able to manifest her dream home.

6 . Eventually, the changes that will strengthen stepfamilies will likely come from shifts in cultural prejudices. Such change is slow, but there are signs that some movement along this line is beginning to take place. For instance, Roger Coleman, a clergyman in Kansas City, Mo., performs marriage ceremonies specifically designed to include children when a parent remarries. In years of officiating second marriages, he says, he became keenly aware of the confusion and insecurities of the children, and the ceremony — which includes a special medal worn by the child — aims to celebrate the “new family” and move the church beyond mere criticism of divorce. This year, Coleman says, over 10,000 families across the country will use the medal in their remarriage ceremony.

Similar changes are occurring in public schools around the country. One of the difficulties for stepfamilies is that schools and other public institutions have typically not recognized the stepparent as a valid parent; school registration forms, field trip permission slips, health emergency information — none of these required or acknowledged the stepparent. The message, whether intended or not, has been that only biological parents count. It’s a message that the stepparent and stepchild internalize, worsening what’s often an already difficult relationship, and one which the larger community takes as another sign that stepfamilies are not legally recognized in American society. Through the efforts of the Step-family Association of America and other advocates, schools around the country have begun changing their policies to acknowledge the increasingly important role of stepparents.

Change is also evident in a marketplace eager to exploit this wide social trend. In a particularly American sign of the times, the Hallmark greeting card company, is about to launch a line of cards devoted entirely to non- traditional families. The cards never use the word “step”, but most of the “Ties That Bind” line is clearly aimed at people who have come together by remarriage rather than biology — or, as one card puts it, “Thrown together without being asked, no chance of escape.” Some are straightforward (“There are so many different types and ways to be a family today”), while others are more indirect (“It’s like at a puzzle where the pieces aren’t where they used to be”). But all are aimed at the vast and growing market of people who don’t identify with the old definitions of family, and who are finding ways to make their new families work. Who knows — soon there may even be a card Tori La Londe can send to her former husband’s former mother-in-law.

7 . A leaked IPCC draft reports, “Widespread use across millions of square kilometers globally of tree-planting and bioenergy crops could have potentially serious consequences for food security and land degradation (退化).” In other words, more massive monocultures (单种栽培) and more bioenergy crops, fueled by more fertilizers, could damage the structure of the environmental soil and its capacity to absorb carbon.

Everyone knows that to help ease the increasing climate crisis, we need to plant new trees. It’s said that the earth could support an additional 9,000,000 square kilometers of forest, potentially hosting 500 billion trees capable of capturing more than 200 billion tonnes of carbon dioxide at maturity. It would be a serious help to the environment.

Bioenergy now holds a 50 percent share of the world’s renewables consumption—as much as hydro, wind, solar and all others combined. It’s good news, but not entirely. If we consider that increasing desertification and rising ocean levels will take away more arable (可耕种的) land, we arrive at a crucial “trilemma”(三难困境). Should we use our spare soil for agriculture, reforestation or bioenergy?

Such a question would make sense in a multilateral, harmonious world, not on a planet where the richest country cancels an environment-saving agreement, thus encouraging the most tropically-forested nation to set about cutting trees.

Last year, 36,000 square kilometers of forest was cut down. Wouldn’t it be better to start by stopping deforestation altogether? Animal farming takes up 77 percent of the world’s arable land and provides us with 18 percent of the calories. Shouldn’t we cut back on global meat consumption? Modern bioenergy is already available. Shouldn’t we get rid of first-generation biofuels, which are produced from food crops?

8 . Lia Thomas, a student at the University of Pennsylvania, is an excellent swimmer. She often beats her rivals by tens of seconds, breaking records. Her success is based on three things. One is natural talent. Another is persistent training. And the third is biology.

For although she identifies as a woman,Ms Thomas was born male.Since humans cannot change their sex (unlike their self-identified gender),she remains that way.On the eve of her biggest competition, Ms Thomas finds herself at the centre of the bad-tempered debate about whether trans women-males who identify as women-should compete in women’s sports.That,in turn,is part of a broader argument: should brute (纯粹的) biological facts sometimes override people’s deeply held feelings about their identities?

This newspaper believes it is almost always unfair to allow transgender women to compete in women’s sports.The advantages bestowed by male puberty (青春期) are so big that no amount of training or talent can enable female athletes to overcome them.Florence Griffith Joyner’s 100-metres world sprinting record has stood for three decades.A male matching it would not even make it to the Olympics, let alone the final.In 2016,at an American event for high-schoolers, four of the eight boys in the 100-metres final ran faster.

Much of the male advantage is granted by testosterone (睾丸素), a potent anabolic steroid whose levels rise sharply in male puberty.For many years,many sporting bodies, following the lead of the International Olympic Committee, hoped to deal with the issue by allowing trans women to compete in women’s events provided they took testosterone-suppressing drugs.But the science suggests this does not level the playing field.Suppressing testosterone in adults, it seems, does little to undo the advantages granted by a male adolescence.

Sports must therefore choose between inclusion and fairness; and they should choose fair play. That does not mean, as is sometimes claimed, that trans women would be barred from all sport.One way to make that clear would be to replace the “men’s” and “women’s” categories with “open” and “female” ones.The first would be open to all comers.The second would be restricted on the basis of biology.

Sport is public, and results can be measured objectively. That means the argument that the material facts of biology should sometimes outrank a person’s subjective sense of identity is easier to make. But bias exists, as a Republican bill in Florida to restrict “instruction” in schools about gender identity or sexual orientation makes plain.

That should be resisted. Most of the time,it costs little or nothing to respect people’s choices about how they wish to present themselves.In the rare cases where rights clash (不相容), society must weigh the balance sensitively and with open eyes.
