1．While most people consider that laughter is one of the nature's great treatments for a whole range of mental and physical diseases，it is still a serious scientific subject that researchers are trying to figure out．
"Laughter is social．"says Robert R．Provine，author of the book"Laughter：A Scientific Investigation"，who has been studying laughter for decades．"Almost all people laugh‘ha-ha-ha'basically the same way．Whether you speak Mandarin，French or English，everyone will understand laughter．There is a pattern generator（发生器） in our brain that produces this sound．
Laughing is also a good way of communicating．Babies laugh long before they speak．No one teaches them how to laugh．They just do it．People may laugh at a prank（恶作剧） on April Fools'day．But surprisingly，only 10to 15percent of laughter is the result of someone making a joke．Laughter is mostly about social responses rather than reaction to a joke．Deaf people laugh without hearing and people on cell phones laugh without seeing，which shows that laughter isn't dependent on a single sense but on social interactions．
And laughter is not just a human thing．Chimps tickle（挠痒） each other and even laugh when another chimp pretends to tickle them．
Jaak Panksepp studies rats that laugh when he tickles them．It turns out rats love to be tickled．They return again and again to the hands of researchers tickling them，Panksepp's video shows．
By studying rats，scientists can figure out what's going on in the brain during laughter．It has been found that laughter in rats produces a chemical that acts as an antidepressant（抗抑郁药） and anxiety-reducer．Scientists think the same thing probably happens in humans，too．This would give doctors a new chemical target in the brain in their effort to develop drugs that fight depression and anxiety in people．
Even so，laughter itself has not been proved to be the best medicine，experts said．"No study has shown that laughter produces a direct health benefit，"Provine said，"largely because it's hard to separate laughter from just feeling good．"

20．Last week I was riding my special motorbike and then stopped at a convenience store．As I was getting my wheelchair off the back，a man watched me from his car and I noticed a wheelchair in his back seat．We spoke for a moment and I asked him about the wheelchair．He answered that it was for his daughter．"Well，do you think she would like to go for a ride on my motorbike with me？"I asked．He seemed shocked that a total stranger would ask him this．He thought about it for a second and said，"OK，as long as I can follow you．"
He introduced me to Amy and he sat her on my back seat．Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas．
As we came back to the convenience store，she said，"This ride is the best Christmas present I could ever receive．I have been in a wheelchair my whole life and didn't know I could do this．"I told her about some of the other things I do （ski，travel the world by myself，etc．）．As her father was taking her off my bike，she turned to him and said，"Oh Daddy，I'm going to be OK．Mr．Bryant does all kinds of things，and I will too．"Her father turned away as a tear of joy rolled down his cheek．He hugged me and said，"I was sitting here praying for a gift for Amy that would encourage her．She often felt that her life was dull compared to other children．God answered my prayer just now．Now I pray that God will bless you for your gift to Amy today．"I believed what he said．Being kind and thoughtful to others，we can be an answer to prayer．
