9．In 2006，Sal Khan launched"Khan Academy"to provide YouTube teaching for his 12-year-old cousin who needed help with maths．The online school now provides more than 580 million online lessons in over 36languages．Last fall，Khan created a physical school in California．
The Khan Lab School runs differently from traditional schools．There's no homework or grades，and students-ranging from ages five to 12-share the same classroom．"It's only 150 years that we separated children by age in classrooms，"said Khan．"The idea is that you can learn a lot from the students who are a little older than you and if you're 12 years old you could exercise a lot of leadership being a teacher assistant for the younger students．"
The school also breaks up the students based on their"independence level，"rather than their age．"Whatever independence level you're on-whether in math，reading or writing-you're on your own track，"he explained．
Another unique feature of the school is that it runs all day，all-year long．Khan said the problem with the current school schedule is that they do not have enough learning time．"The gap between the U．S．and Shanghai test scores can be explained by time in the classroom，"Khan said．"You have the summer learning loss，which is not only time that you're not learning when you could be，but also you're forgetting the things that you learned at the end of last year．"
Now Khan Lab School enters its second year．Khan said he hopes to use the reach of the Khan Academy，which has more than 30 million users now，to send students and teachers in other schools information on how to create similar learning experiences in their classrooms．

8．When I was nine years old，I loved to go fishing with my dad．But the only thing that wasn't very fun about it was that he could catch many fish while I couldn't catch anything．I usually got pretty upset and kept asking him why．He always answered，"Son，if you want to catch a fish，you have to think like a fish"，I remember being even more upset then because，"I'm not a fish!"I didn't know how to think like a fish．Besides，I reasoned，how could what I think influence what a fish does？
As I got a little older I began to understand what my dad really meant．So，I read some books on fish．And I even joined the local fishing club and started attending the monthly meetings．I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature．That is why fish prefer shallow water to deep water because the former is warmer．Besides，water is usually warmer in direct sunlight than in the shade．Yet，fish don't have any eyelids（眼皮） and the sun hurts their eyes…The more I understood fish，the more I became effective at finding and catching them．
When I grew up and entered the business world，I remember hearing my first boss say，"We all need to think like sales people．"But it didn't completely make sense．My dad never once said，"If you want to catch a fish you need to think like a fisherman．"What he said was，"You need to think like a fish．"Years later，with great efforts to promote long-term services to people much older and richer than me，I gradually learned what we all need is to think more like customers．It is not an easy job．I will show you how in the following chapters．

3．The entire family was here recently-14 in all，including six kids under the age of 5．We had a joint birthday party for two of the grandkids．
The day after everyone cleared out I noticed that the drain stopper（排水塞） was missing from downstairs bathroom sink．
The last thing you want to do is accuse your own fresh and blood of stripping hardware from your bathroom，but a drain stopper doesn't just wash itself down the drain．
So I sent out a carefully-worded e-mail saying what a wonderful time we had and asking if anyone had accidently tucked a drain stopper in a purse，pocket or suitcase．I even attached a picture of a drain stopper in case there was any doubt as to what the missing part looked like．
Our son responded that he thought his 10-month-old might have eaten it．He said he'd let us know if they found it in the next day of two．
Our youngest daughter responded that she thought she saw it in her husband's lunchbox that morning，but she could be wrong．
Our oldest daughter replied that she had suspected her sister's husband all along．He replied that he had been framed．
Our oldest daughter then checked the guilt of one of her twins with following exchange：
Mommy："Do you know where Grandma's drain stopper is？"
Three-year-old："Yeah，let me show you．"（Heads to the bathroom．）
Mommy："No，not ours，where is Grandma's？Did you take it？"
Three-year-old："I think she took it．"（She points at her 18-month-old baby sister）．"She's a naughty kid．"
Naturally，the 18-month-old defended herself by saying："Bububbubnananabublalala!"
The next day，an email arrived from our daughter-in-law．"Guess what I found in my laundry this morning？I thought the dryer was louder last night．"
Our "perp" was short．He has a known history of building and disassembling，is mechanically inclined，determined and just turned 3．
It's always good to know a child's interests and talents．We have a valve（阀门） that occasionally drips under the kitchen sink．I may have him take a look at it the next time he's here．But I'll pat him down before he leaves．
