Mary and her husband Jim had a dog named “Lucky”．Whenever Mary and Jim had friends come for a weekend visit，they would warn their friends not to leave their luggage open because Lucky would steal something from their luggage and he always hid his finds in his toy box in the basement.

    It happened that Mary found out she had breast cancer.She felt she was going to die of this disease.The night before she was to go to the hospital，a thought struck her，“What would happen to Lucky？” “If I die，who will look after Lucky？” Mary thought.The thought made her sadder than thinking of her own death.

    Mary stayed in the hospital for two weeks.Jim took Lucky for his evening walk every day，but the little dog just looked sad and miserable.

    Finally the day came for Mary to leave the hospital.When she arrived home，Mary was so tired that she couldn't even make it up the steps to her bedroom.Jim made his wife comfortable on the bed and left her to sleep.

    Lucky stood watching Mary but he didn't come to her when she called.It made Mary sad.But she felt so sleepy that soon she fell asleep.

    When Mary woke，for a second she couldn't understand what was wrong.She couldn't move her head and her body felt heavy.But panic(惊慌) soon gave way when Mary realized the problem.She was enclothed with a blanket，and with every treasure Lucky owned!

    While she had slept，the sorrowing dog had made trip after trip to the basement bringing his beloved hostess all his favorite things.He had covered her with his love.

    It's been 12 years now and Mary is still living.Lucky? He still steals treasures and hides them in his toy box but Mary remains his greatest treasure.

    A handshake is one of the most common ways to greet others, but US President Donald Trump's unusual method has been put under the microscope lately.

    Much like an arm wrestler in a match, the recently-elected leader has a habit of yanking (猛拉) people's hands toward himself during handshakes. And while a typical handshake is only brief, the one between him and Japanese Prime Minister Shinzo Abe on Feb 10 lasted a full 19 seconds.

    Simply having a strong hand is not the explanation here. According to Darren Stanton, a body language expert from the UK, while handshakes are usually an exchange of kindness, Trump uses his as a way to show power and control, regardless of how uncomfortable it makes people. “It is as if to say, 'Hey, I'm in charge, don't mess with me,' ” Stanton told The Independent.

    Apart from Trump's “yank-shake”, there are other ways people display power with their hands. At business talks or political meetings, for example, some people may rotate (旋转) their wrists during handshakes so that their hand ends up on top instead of underneath. Some may squeeze so hard that it leaves the other person's hand in pain.

    According to Stanton, by pulling people into his personal space, Trump is also testing whether they are willing to cooperate with him. “For example, if someone was resistant to being yanked towards him and stood their ground, he would know that he has work to do with them before he got what he wanted,” Stanton told Express.

    This is probably why on Feb 13 when Canadian Prime Minister Justin Trudeau visited the White House, all eyes were on how he was going to handle Trump's handshake. Fortunately, Trudeau managed to avoid the embarrassment by grabbing Trump's shoulder to stop himself being pulled in. Afterward, some Twitter users wrote that this proved Trudeau's strong leadership, with one even calling the moment “one of Canada's greatest victories”.

    Vice magazine summed up the exchange between the two leaders as: “... no regular handshake. This was the first shot in a bloodless war.”

    South Africa is a multiethnic society encompassing a wide variety of cultures, languages, and religions. It has 11 official languages. If you want to say hello, it's "sawubona" in Zulu, and "hallo" in Afrikaans. Now, South Africa's school children may start using "ni hao" to say hello.

    The country's education minister says, the nation is adding the Mandarin language teaching in some schools. Mandarin is the official spoken language of China. That country is a major trading power for South Africa.

    A recent agreement between the two nations centers on five areas of cooperation. They include development in basic education, school books and lessons, mathematics and science, teacher training and career education and research.

    South Africa officials have not said how much they teaching Mandarin will cost. Troy Martens is an officials with South Africa's Ministry of Basic Education. She says the new partnership is extremely valuable.

    A public opinion study last year found that South Africans have mixed feelings about China. The survey showed 46 percent of South Africans do not like the spread of Chinese ideas and customs in their country, the results also showed that 60 percent dislike Chinese music, movies and television.

    But Ms Martens said Chinese trade is more important than those feelings. She said it is extremely helpful to learners in South Africa to study Mandarin as well as Chinese culture. And she said not every school will offer Mandarin.

    “Now this will not be compulsory, it will not be for every school, and it will not be for every child. But for schools that feel they have the capacity to offer Mandarin as a subject, we think it is a great opportunity for South African learners to be exposed to this international type of language,” said Martens.

    Lisette Noonan heads the 80-year-old Pretoria Chinese School in South Africa's capital. The school serves about 500 students from kindergarten to grade 12. Every student studies Mandarin.

    Ms Noonan says the school welcomes the new cooperation between South Africa and China. She said it is in the best interests of children to study Mandarin. She said that especially true with China becoming what she called “a huge economic power in the world”

    Some of the most famous universities in America are urging students to consider the idea of putting off college for a year. It's called a “gap year.” And while it's been common and popular in Australia and the U.K. for decades, the concept is now starting to gain significant steam here in America.

    Why? A growing number of high school seniors are tired of riding the academic conveyor belt from preschool all the way to university. They're burnt out. Or not quite ready. Or they want to explore a few interests before deciding what to study in college, they're volunteering in New Orleans or teaching in Thailand. They're starting the great American novel, or working for a short time to help figure out what they want to do with their lives.

    Understandably, that makes a lot of parents nervous. But a gap year does not mean that a student will remain degree-less forever. While there are no formal studies on the number of students who don't finally go to college after the gap year, evidence from admissions officers across the country says very few actually leave college without finishing their courses. Taking a gap year can actually make kids more focused and ready for future academic life. In fact, Harvard University believes so much in the gap year that it encourages every student it admits to consider a year off before matriculation (入学).

    The reason behind higher education's support of the gap year is clear: Better-prepared students mean higher completion rates. And it's completion that matters. Parents should remember that getting a kid into college is only half the battle. According to the College Board, three out of five students who enter a public four-year college don't manage to obtain a degree within five years. And nearly 30 percent of all students who enter college don't return after the gap year. Considering the fact that this year's average price at a four-year private college is about $ 23,712 per year, it's a pretty expensive place to play around.

    Shoppers in the UK are spending less money on toilet paper to save money, research has shown.

    Penny saving UK consumers choose cheaper products from discounters such as Aldi and Lidi rather than expensive alternatives.

    This has wiped 6% off the value of the soft tissue paper market in the UK. It has reduced from £1.19 billion in 2011 to £1.12 billion in 2015, according to a new report from market research company Mintel. Furthermore, the future of the market looks far from positive, with sales expected to fall further to £1.11 billion in 2016.

    In the last year alone, despite an increase in the UK population and a rise in the number of households, sales of toilet paper fell by 2%, with the average household reducing their toilet roll spending from £43 in 2014 to £41 in 2015.

Overall, almost three in five people say they try to limit their usage of paper – including facial tissue and kitchen roll    to save money. “Strength, softness and thickness remain the leading signs of toilet paper quality, with just a small part of consumers preferring more expensive alternatives, such as those with flower patterns or perfume,” said analyst Jack Duckett. “These extra features are considered unnecessary by the majority of shoppers, which probably reflects how these types of products are typically more expensive than regular toilet paper, even when on special offer.”

    While consumers are spending less on toilet paper, they remain particular about it when it comes to paper quality. One in 10 buyers rank toilet rolls made from recycled paper among their top considerations, clearly showing how overall the environment is much less of a consideration for shoppers than product quality. In a challenge for makers, 81% of paper product users said they would consider buying recycled toilet tissue if it were comparable in quality to standard paper.

    Researchers say getting a good night's sleep is probably the best tool for memory and learning. But short periods of sleep may help our brains work better, says a recent study on napping. And taking a nap  may also help old adults fight off age-related memory loss.

    CDC, an American scientific organization, found that 50 to 70 million Americans have chronic（长期的）sleep disorders. So, someone who naps as a way of paying off a sleep debt may not experience the same improvements from napping as a well-rested person would. Also, that only children, the very old, sick or  lazy people nap is not an uncommon opinion.

    Researchers recently looked at information provided by nearly 3,000 Chinese adults, aged 65 years or older, to learn if napping after a mid-day meal had any effect on the mental performance of the subjects.

    First, they asked the people if they napped and for how long. Then, based on their answers, researchers put them into four groups: non-nappers (0 min), short nappers (≦30 min), moderate nappers (30-90 min), and extended nappers (≧90 min).  Nearly 60% of the people said they did take a nap after lunch and that   their naps lasted anywhere from 30 to 90 minutes. Most of the subjects said they napped for about an hour.

    The study found that people who took an hour-long nap did much better on mental tests than those      who did not nap. The hour-long nappers also did better on the tests than those who napped for shorter and longer periods. In this study, it seemed that the most effective nap lasted for about an hour, but not much longer.

    Yet Doctor Michael Twery notes that an hour long nap may be too long for young, healthy adults. 30 minutes is enough to remove the pressure to sleep and will help us feel more awake.
