　　Matt Mason has seen the future—and it’s fun．Mason likes thinking about how machines can make our lives easier by doing the work we hate, such as cleaning．He shows a hard floor cleaning system (系统) that’s built into the wall： it will blow dirt to a part of the room where it will be collected by a vacuum (吸尘器) ．Then the system will drop some cleaner on the floor and an arm will mop (用拖把擦) it up．“This may trouble you,” says Kara, an expert in Mason’s company．“But you can program it to come on at 3 a ．m, and it will just wet － mop the floor for you．”

　　When it comes to the kitchen, Bruce Beihoff, another expert at Whirlpool, is sure that in a few years, robots will be doing most of the boring work, freeing us to relax．“More than just fun, future kitchens will be environmentally friendly,” he says．“A new system will be built in the house which can recycle energy (能量) lost from your kitchen to make the whole home warm．”

　　“The fridge will be the center of the home,” says Daniel Lee, a market expert．The fridge will have a touch screen (触摸屏幕) where you can watch TV, surf the Internet, check your e－mail, keep a shopping list and order vegetables．“Your fridge is the first place you go in the morning and the last place at night,” says Lee．

　　Ever wonder why a 1.9－meter man and a 1.6－meter woman have to cook meals on counters (工作台) of the same height．“The height was decided over 50 years ago, according to the height of ordinary women,” says Jane Langmuir, an expert of cooking machines．“But times have changed．We have made a new counter where you press a button and it moves to whatever height you want．” At the same time, Ted Selker at MIT’s Counter lab has made the Dishmaker which lets you make dishes and bowls out of plastics at home．After each meal, the dishes are changed straight back into plastics．

　　Have successful people ever felt sad? Do they have any “secrets” to success? The answers to these questions can be found in US president Barack Obama's “back to school” speech．Here is an excerpt(摘录)from his speech．

　　I know that sometimes, you get the sense that you can be rich and successful without any hard work-that your ticket to success is through pop music or basketball or being a TV star, when chances are, you’re not going to be any of those things．

　　But the truth is, being successful is hard．You won't love every subject you study．Not all the homework will seem rather important to your life right this minute．And you may not succeed at everything the first time you try．

　　That's OK．Some of the most successful people in the world are the ones who’ve had the most failures(the opposite of success)．JK Rowling's first Harry Potter book was turned down 12 times before it finally came out．Michael Jordan was cut from his high school basketball team, and he lost hundreds of games and missed thousands of shots(投篮)during his career．But he once said, “I have failed over and over again in my life．And that is why I succeed．”

　　These people succeeded because they understand that you can't let your failures beat(打败)you-you have to let them teach you．You have to let them show you what to do differently next time．

　　No one's born being good at things．You become good at things through hard work．

　　Don't be afraid to ask questions．Don't be afraid to ask for help when you need it．I do that every day．Asking for help isn't a sign of weakness; it's a sign of strength．It shows you have the courage to tell when you don't know something, and to learn something new．

　　And even when you’re struggling(奋斗), even when you’re discouraged (泄气), and you feel other people have given up on you－don't ever give up on yourself．Because when you give up on yourself, you give up on your country．

　　“No man is an island” is a well-known line from John Donne's Devotion．It was written more than three hundred years ago．Even now people still agree with him．No one can live a completely lonely life．Without other people, life will become empty and sad．We all need to have friends．

　　For some of us, although making friends is not difficult, feeling shy, we may not want to make the first move．It is also difficult at times to keep the friends we already have．

　　There are many books about friendship, but Dale Carnegie's How to Win Friends and Influence People, written in 1936, is the most famous．This “how to” book about getting along with other people became a best seller．It was later put into 28 languages．

　　Dale Carnegie's advice seems to be simple, but can his advice help you? Do you need to change the way you act? Here is the list of advice from his book：

　　Be friendly and polite．

　　Always greet with a smile．Begin with “Excuse me” or “Would you please” when you want to ask somebody．Remember to say “Thank you” and try to be as helpful as you can．

　　Go out of your way to be nice．

　　Find some time to do special things for other people．Making some soup for a sick neighbour may seem like a little thing to you, but it will make your neighbor feel a lot better．

　　Remember names．

　　They say that the sweetest music to a person's ears is the sound of his or her own name．

　　Be open-minded．

　　Try to understand other people's ways and ideas and learn something from them．

　　Listen patiently．

　　When someone is talking to you, look at him or her, listen carefully and say something when necessary．

　　The willful blindness in hockey toward concussions(头部撞击)has dropped．Hockey Canada has followed the lead of USA Hockey in preventing bodychecking(身体拦截)below age 13．A bad head injury of Sidney Crosby, the hockey's greatest star, opened the eyes of hockey people everywhere．This country's children have been facing similar danger at early ages, and Hockey Canada had to deal with a deep worry in the minds of Canadians to make the rule change．The liking for bodychecking from an early age is part of what makes Canadian hockey what it is．

　　The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger．It may also control the loss of thousands of young players who don't enjoy that environment．

　　For years, many Canadian hockey parents and coaches have insisted that bodychecking at early ages is necessary to ensure that players can do it safely at older ages．True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries．When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory(强制的)for all coaches, including those teaching players in the pre-checking ages．And it began to encourage more "touch"-without real bodychecking-from 9 t0 12．It also made the rules for 13 and up stricter．The USA is trying to show that it's possible to teach hockey protective skills without putting11 and 12-year-olds in greater danger．It's worth the try．

　　Hockey Canada has taken serious steps to do away with hits on the head．However, it's hard to change a sports culture so connected with who we are as a country．Too often, bodychecking has been used to try to separate a player from his head rather than from the ball．Children were paying a price for this country's love of the game．

　　There are always changes in Canada's game, and the change in the bodychecking age sends the clearest message yet to coaches and parents that player safety is paramount(至上的)in the game．
