Our warming planet is expected to face serious water crisis（危机）in the coming decades — which means each nation's natural resource will be more important than ever.

    When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.

    Encouraging pupils to keep noise to a minimum should be a valuable part of all children's education, according to a new research.

    Dr. Helen Lees, from Stirling University's school of education, says that “enforced (强制的) silence” is seen as a punishment and often acts to suppress children's natural ability. But she says that teaching children about the benefits of “enforced silence” — deliberate stillness that gives them the opportunity to focus and reflect in a stress-free environment — can have a significant effect on pupils' concentration and behaviour.

    It is the latest in a string of researches to establish a link between the classroom environment and pupils' academic ability.

    A study almost a decade ago in London found that children's exam results were cut by as much as a third if they taught in noisy classrooms. Teaching unions have also called for a     limit of 26℃ to be put on classroom temperatures because teachers and pupils struggle to work in hot conditions and some educationalists claim that too much clutter(杂乱的东西) on classroom walls can prevent children from concentrating.

    Dr. Lees said: “When we take some research on school settings and put it all together, what we see is that education without silence does not make much sense. In areas of better learning outcomes, better self-confidence and well-being measures, enforced silence in a person's life and an individual's education is shown throughout the relevant research to be a benefit.”

    Dozens of schools across Britain already introduce periods of “reflective silence” into the timetable.

    Kevin Hogston, head of Sheringdale Primary, south London, has just introduced a minute's silence at the start of twice-weekly meetings in which children are taught breathing techniques and encouraged to reflect. The school plans to introduce it into classrooms every day.

    Are you looking for some great beach movies? If you are, here are some beach movies that you are advised to watch.

    Blue Hawaii (1961)

    The first of Elvis Presley's Hawaiian three beach movies puts him into a setting(背景) as an army man who returns home for some surfing. Mom Angela Land sbury wants Presley to get a real job, but he's all about touring the island. Relax, Mom. Time for some wonderful parties!

    Beach Blanket Bingo (1965)

    The most famous of the “beach party” film of the 1960s stars Frankie Avalon and Annette Funicello. This movie is all about how fun it is to be a teenager, especially if you're at a party on the beach. Sunny, silly and energetic! You might find yourself laughing at the story and being happy after watching it.

    Six Days Seven Nights (1998)

    Anne Heche stars a woman unhappily engaged (订婚) to Frank Martin. On a vacation, she finds herself on a plane piloted by a sad man called Quinn Harris. They hate each other, which gets even more annoying once they two find themselves being alone on an island with no people. What better setting to fall in love?

Teen Beach Movie (2013)

    The Disney Channel remade the beach party movie in 2013 and brought us a new series of teens-dancing-on-the-beach movies. Ross Lynch is a kid suddenly thrown into a actual teen beach movie by a magic wave! Time to dress up fifties-style and sing tunes (曲调) like Surf Crazy and Cruisin for a Bruisin. In the end, the kids return to the real world. These are the movies to watch if you love happy endings.

Your 2018 Reading List, Provided by Bill Gates

    Most of us can't live like billionaire Microsoft co-founder Bill Gates, but we can read like him. Gates recommended four books in 2018—though some were published earlier.

    Leonardo da Vinci, by Walter Isaacson (2017)

    The bestselling biographer of Steve Jobs and Albert Einstein researched deeply into da Vinci's contributions beyond art, highlighting the breadth of his scientific, technological, and creative output. “Leonardo nearly understood almost all of what was known on the planet at the time. That's mostly because of his curiosity about every area of natural science and the human experience,” said Gates.

    The Best We Could Do: An Illustrated Memoir, by Thi Bui (2017)

    Gates calls this graphic novel “really impressive”. Bui is the daughter of Vietnamese refugees who came to America after the fall of Saigon, and becoming a parent inspired her to look into her own parents' miserable history. “I was struck by how the experiences Bui illustrates manage to be both universal and specific to their circumstances,” said Gates.

    Lincoln in the Bardo, by George Saunders (2018)

    Saunders, a long-time short story writer, won high praise for this novel. The book imagines the ghosts that haunt (萦绕) the basement of Willie Lincoln, Abraham Lincoln's son, who died at 11 in real life. “Willie's death after the Civil War made the president have a new understanding of the grief he's creating in other families by sending their sons off to die in battle,” said Gates.

Origin Story: A Big History of Everything, by David Christian (2018)

    This new book is by the creator of Big History, a free, online social studies course. It traces history in wide, sweeping movements, starting with the Big Bang, and it provides, in effect, a short course in modern science. This is a brief history of the universe. “David gets a little stuck on the current economic and political problems in the West, and I wish he talked more about the role innovation will play in preventing the worst effects of climate change,” said Gates.

    China became the first country to clone a monkey using non-reproductive cells, reducing the need to keep lab monkeys and paving the way for more accurate, effective, and affordable animal tests for new drugs.

    By December of 2017, Chinese scientists had created two clone macaques named "Zhong Zhong" and "Hua Hua" by nuclear transferring of somatic cells -- any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.

    Tetra, a rhesus monkey born in 1999, is the world's first ever-cloned monkey, but it was done using a simpler method called embryo splitting, but it could only generate four cloned offspring at a time and cannot be genetically modified to suit experimental needs, said Pu Muming, an academician at the Chinese Academy of Sciences and the director of Institute of Neuroscience, CAS. "Cloning a monkey using somatic cells has been a world-class challenge because it is a primate（灵长类）that shares its genetic makeup, therefore all of its complexity, with humans." Pu Muming said.

    "For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each monkey might have different genes," Pu said. "By cloning monkeys using somatic cells, we can mass produce large numbers of genetically same offspring in a short time, and even change their genes to suit our needs," he added. "This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine."

    Sun Qiang, director of the non-human primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different. "Monkeys and Humans are both primates, so they are much closely related and testing on Monkeys is supposed to be as effective as testing on humans," he said. This is especially useful in testing drugs for neural diseases such as Parkinson's disease, metabolic and immune system disease, and tumor, he added. "This achievement will help China lead the world research in an international science project related to neural（神经的）mapping of primate brains,"he said. However, bio labs from the United States, Japan, and European countries are also very able, and they will quickly catch up to China after the monkey cloning technology is made public, Sun added." This means we have to innovate continuously and work extra harder this year to stay ahead," he said.
