When we're in need, we always turn to our parents for help. But would you like them to hear the conversations you have with your friends on the school playground or lunch queue? Social networking sites have become extensions (延伸) of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends?

    In the past the generation gap included a technology gap, where children were up to date with latest technology and parents were left behind, content to continue their day to day lives as they always had because they had no need to know more about technology. However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to educate themselves about social networking sites.

    These days many people are attracted to social networking sites because they can choose who they have around them; there's also a certain amount of control over privacy that we don't get in real life. Sometimes we feel that privacy is violated (侵犯）when we must accept a “friend” request from a parent or family member.

    It's a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don't want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before.

    A recent survey suggested that parents shouldn't take it personally if their child ignores their request: “When a teen ignores a parent's friend request, it doesn't necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to be independent.”

    Perhaps talking with parents and giving explanations would help soften the blow if you do choose not to add them to your friends list.

    Like most July days, it was hot. I stepped into a tiny ice-cream shop to cool off with a chocolate ice-cream. It was an old-time store with little round tables and chairs.

    As I entered, I found a very old woman bent over a table near the door. Her back was so badly twisted by some sadness that her face nearly touched the table top. I sat down facing her several tables away.

    “Poor woman,” I thought. “What does she get out of life? Why God let people live so long past their prime?”

As I thought, another aged lady entered the shop and sat down with her. Soon the two of them were talking about childhood days. They talked of how little the shop had changed in 70 years… In minutes, the two of them were trembling with laughter.

    I looked again at the first woman, then in the mirror on a nearby wall, catching a picture of myself.

I was wearing a dirty shirt. She was well dressed in white, her hands shining with gold rings.

    I was gloomy(愁闷的). She was laughing, smiling.

    I was putting the pieces of my life together. She had millions of wonderful memories to recall.

    I sat alone. She was sharing the day with a good friend.

I was secretly worried about getting old. She was old, but it wasn't hurting her.

    As I left the shop, I thought of my foolish question about God letting people live past their prime. Why, that woman was more alive, more sensitive to life than I was. Age has not bent her spirit.

    In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.

    But why , they pleaded. “Because I don't have time to take care of a dog.” But we'll do it. ” Really? You're going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don't believe you .” We will . We promise.

   They didn't . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”

    Quickly, she and I developed something very similar to a Vulcan mind meld (心灵融合) . She'd look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .

    Even so , part of me continued to resent walking duty . Joe and Becky had promised. Not fair , I'd balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I' d loudly remind anyone within earshot upon our return home .

    Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.

    Save one: Misty still needed walking. At the beginning, when friends offered to take her through her paces, I declined because I knew they had their own households to deal with.

    As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.

    When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.

    Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or 'one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.

After Joe died in 2009，Misty slept on his pillow.

    I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m' walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.

    The 2012 Nobel Prize for Literature was awarded to Mo Yan for his writing that mixes folk tales, history and the modern events with hallucinatory realism（魔幻现实主义）, the Swedish Academy announced.

    The 57-year-old is the first Chinese resident to win the prize. Only one other Chinese-language writer has won the Nobel Prize for Literature. Gao Zingjian was honored in 2000. However, he is a French citizen.

    Mr Mo said he was “overjoyed and scared” when he learned he had won the award. He will receive his Nobel diploma, a medal and more than one million dollars at a ceremony in Stockholm in December.

    China is celebrating the victory of this native son. Minutes after the award was announced, millions of Chinese expressed pleasure and pride for Mo Yan on social media websites. Senior CPC leader Li Changchun has congratulated Mo Yan on winning the 2012 Nobel Literature Prize. Li says in a letter to the China Writers Association that Mo's winning of the prize reflects the prosperity and progress of the Chinese literature.

    His real name is Guan Moye. Mo Yan means “Don't Speak.” The writer said he chose the name to remember to stop his tongue from getting him in trouble. Mo Yan's novel “Red Sorghum” first became a cable hit on the big screen both at home and abroad in 1987. The film was directed by Zhang Yimou and marked the acting start of Gong Li.

    As a productive author, Mo has published dozens of short stories, with his first work published in 1981. Mo Yan's other major works include, “Big Breasts and Wide Hips,” “Republic of Wine” and “Life and Death Are Wearing Me Out.”

    It's comforting to think if you were somehow swallowed by a whale, you'd simply hang out in his stomach until he eventually spat you out, unharmed and whole. Unfortunately, your chance of ending up in this type of situation is pretty low.

    In 2012 reporter Ben Shattuck read the records at the New Bedford Whaling Museum Research Library. Despite his extensive research at one of the most comprehensive whaling archives(档案), he failed to find a single report of anyone ever being swallowed alive by a whale. He found plenty of reports of whalers who were bitten or injured by the creatures, and several who died after fighting with a whale, but none related to swallowing.

    With whales' large mouths, it certainly seems possible that a whale could swallow someone whole, so why is it so unlikely? Baleen whales, or whales without teeth, are some of the largest creatures on the planet. Despite their massive size, baleen whales could never get you into their bellies thanks to their relatively small esophagus(食道). These whales are designed to eat small sea creatures, and the opening in their throat is only about as large as a basketball, so you'd never make it that far.

    But what about toothed whales? Sperm whales eat whole seals, so you could easily fit down their throats and into their stomachs. However, once you reached the first of the sperm whale's four stomachs, your journey would probably end quickly. Not only would the whale's stomach acid make quick work of you, but you'd experience a distinct lack of air on the inside. Actually, you're more likely to get eaten or injured as you try to make it past the sperm whale's sharp teeth. Plenty of whalers, have fought with sperm whales and lost their hands or lives due to these mean teeth.

Where does the meat on our table come from? It usually comes from livestock like chickens and cows. But did you know that meat can also be made in a lab? US company JUST has announced that lab-grown meat could be on some restaurant menus in the United States and Asia by the end of 2018, The Independent reported. 

"These meats include chicken nuggets (鸡块), sausage and foie gras (鹅肝酱), " Josh Tetrick, CEO of JUST, told The Independent. Lab meat is sometimes referred to as "clean meat". It is made using the stem cells (干细胞) of living livestock. The cells need to be grown in a lab for a few weeks. For example, making a hamburger patty (肉饼) takes about nine weeks, CNN reported. This is faster than raising a cow, which usually takes over 20 weeks. 

The first clean meat was a beef burger that was produced in 2013, but it was said to taste quite dry. How does clean meat taste now? Clean meat supporters told CNN that they think it tastes just like traditional meat. 

Clean meat has other advantages. It is healthier than traditional meat. Meat producers can control what type of fat goes into the meat. They can produce clean meat that contains healthy fats, such as omega-3 fatty acids (脂肪酸). This kind of fat is good for people's hearts. 

Clean meat can also help to solve global warming. According to The Washington Post, about 14. 5 percent of the planet's greenhouse gas emissions (排放) come from raising livestock. That's more than the emissions from every car, train, ship and airplane in the world combined. It is predicted that switching to clean meat could lower greenhouse gas emissions by 96 percent, The Independent reported.
