Each “ha” is about one-15 of a second, repeated every fifth of a second, repeated every fifth of a second, he said. Deaf people laugh without hearing, and people on cell phones laugh without seeing, showing that laughter isn’t dependent on a single sense but on social interaction(交流) with life,” said Jaak Panksepp, a Bowling Green University psychology professor. “It’s deeply social.”
And it’s not just a people thing either. Chimps tickle (挠痒) each other and even laugh when another chimp pretends to tickle them.
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.
By studying rats, Panksepp and other scientists can figure out what’s going on in the brain during laughter. And it holds promise for human ills.
Northwestern University biomedical engineering professor Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant(抗抑郁药). He thinks the same thing probably happens in humans, too. This would give doctors a new chemical target （目标） in their effort to develop drugs that can fight depression.

Even so, laughter itself hasn’t been proven to be the best medicine, experts said.
Margaret Stuber, a professor at University of California studied whether laughter helped patients. She found that distraction(分心) and mood improvement helped, but she could not find a benefit for laughter alone.
“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. But he thinks it doesn’t really matter: “Isn’t the fact that laughter feels good when you do it enough”

5. Keep believing in yourself (4.12)
The professor stood before his class of 30 senior
molecular(分子的) biology students, about to pass out the final
exam. “I have been privileged(荣幸的) to be your instructor this semester, and I know how hard you have all worked to prepare for this test. I also know most of you are off to medical school or grad school next fall,” he said to them. “I am wee aware of how much pressure you are under to keep your GPAs (平均成绩) up, and because I know you are all capable of understanding this material, I am prepared to offer an automatic ‘B’ to anyone who would prefer not to take the final.”
The relief was audible (听的见的) as a number of students jumped up to thank the professor and left the class.
The professor looked at the handful of students who remained, and offered again, “ Any other takers This is your last opportunity.”
One more student decided to go.
There were seven students left. The professor closed the door and took attendance. Then he handed out the final exam. There were two sentences typed on the paper:
“ Congratulations, you have just received an ‘A’ in this class. Keep believing in yourself.”
I never had a professor who gave a test like that. It may seem like the easy way out of grading a bunch of exams, but
it’s a test that any teacher in any discipline(学科) could and should give. Students who don’t have confidence in what they’ve learned are “B” students at best.
The same is true for students of real life. The “A” students are those who believe in what they’re doing because they’ve learned from both successes and failures. They’ve absorbed life’s lessons, whether form formal education or the school of hard knocks, and become better people.
Take your cue(榜样) from Sir Edmund Hillary, the first person to reach the summit (顶点) of Qomolangma; “It’s not the mountain we conquer, but ourselves.” Don’t let the biggest limit be yourself.
1. The professor offered to give an automatic “B” to those who would prefer not to take the final because_______.
A. he thought all of his students had prepared for the test well.
B. he believed all the students were able to pass the exam C. he didn’t want to place too much pressure on his students D. he intended to tell his students about the importance of confidence
2. According to the text, which of the following statements is TRUE
