Your biology teacher may insist that science is not a laughing matter，but scientists would argue that laughter is a scientific matter.These scientists have found a basic difference in how men and women laugh.
Jo-Anne Bachorowski and her research team recorded the laughter of 97 volunteers.The volunteers watched clips（電影片段） from funny movies.The scientists were surprised at the variety of sounds people made when they laughed.Rarely did they hear sounds that we stereotype as laughter such as "tee hee hee" or "ho ho ho." More often they heard vowel （元音） sounds such as those heard in "car" （aah） or "glow" （ooh）.What's more，women tended to laugh in a more sing-song way，while men more often grunted （發(fā)出哼聲）.
The researchers caution that this work was limited to people in the United States，so the results may not be universal.Bachorowski predicts that cultural influences may affect what causes people to laugh，but it probably does not change how we laugh.
Although we do laugh at jokes and funny movies，80% of our laughter occurs during everyday comments in everyday social situations.Robert Provine，a neuroscientist who studies laughter，went to places such as shopping malls and collected more than 1，200 conversations.He found that the person speaking laughed 46% more than the listeners and that women laughed more often than men.Furthermore，the response to the speaker depended on the speaker's gender.People，whether male or female，laughed more readily in response to a male speaker.The researchers also observed that laughter rarely interrupted speech.Instead，laughter came at the end of a phrase，much like punctuation following a written sentence.
Humans may be "tuned（使協(xié)調(diào)）" for laughter much in the same way that songbirds are "tuned" for song — especially their own specific family song.Certain nerve cells （神經(jīng)細(xì)胞） in the songbird's brain "fire" in response to hearing his song.Perhaps humans have specialized nerve cells that respond to laughter.After all，laughter is a specialized vocalization，and we are "tuned" to respond to vocalizations in language.

1．For some people，the warmest memories from childhood come from being read a great story．（1）
It develops children's language skills and increases their ability to succeed in school and，later，work．

（5）Of all the six to 17-year-olds in the Scholastic study，more than 90%said their favorite books are the ones they chose for themselves．
A．The Scholastic report also suggests permitting children to choose their own books．

2．Chinese students always complain that they're under great pressure and don't get enough sleep.But they may be surprised to learn that they're much luckier than their peers（同齡人）in South Korea and Japan，according to a recently published report，conducted by Shanghai Academy of Social Sciences on the physical and mental health of senior high school students in the three Asian countries.
According to the study among nearly 6，000 high school students in the three countries，Chinese students are the tallest but poorest in physical fitness.Chinese students are on average 168.17cm，compared with 167.61cm for South Korean students and 164.70cm for Japanese students.Chinese students asked for sick leave more than students in other countries.About 72 percent of Korean students never asked for sick and injury leave during high school，compared to 53 percent for Japanese students and 45 percent for Chinese students.Moreover，Chinese students drink alcohol and smoke earlier than Korean and Japanese students.Around 70 percent of Chinese students have drunk alcohol，compared to 50 percent for Korean and Japanese students.
According to the survey，Japanese and South Korean students suffer more pressure than their Chinese peers.Statistics show 16 percent of students in China said they experienced mental pressure often over the past year，while the numbers in Japan and South Korea were 33 percent and 47 percent respectively.Their worries come from "study"，"future after graduation"， "friendships" and "relationship with their parents".To go with stress，57.9 percent of Korean students sleep the least，less than six hours a day，compared with 46.6 percent of Japanese students and 30 percent of Chinese students.
More Chinese students were satisfied with their physical appearance，double that of students in the survey from Japan and South Korea.The report said that over half of students in South Korea had tried to lose weight in the past year，while in China the figure was only 22 percent.In measures of self-worth，such as "I think I am valuable" and "I think I am successful"，"I can complete many things"， "I won't give up to failure，" Chinese students showed greater self-confidence than students in Japan and South Korea.

3．Paying ﹩25，000 to get your pet cloned might sound attractive，if you have the money and can't imagine life without your pet.
There are two companies now that can clone your pet：ViaGen and Sooam Biotech.Lab techs there will clone your pet using a process called somatic cell nuclear transfer （體細(xì)胞核移植），the same method used to clone Dolly the sheep in 1996.This involves removing the nucleus from a female's developing egg cell and replacing it with the nucleus from a cell from the animal you want to clone.The new cell is then stimulated （刺激） with an electric shock to make it divide and then implanted into a host organism （有機(jī)體）.
The decision to clone your pet has to take place while they're still alive.You need to sign up with the company and take your pet to the vet so they can harvest some cells.Then，for between ﹩1-2000，the company will store the cells.Even if you decide to stop，there's no refund for the storage.If you decide to have your pet cloned，you'll pay a much larger deposit to perform the cell transfer and implant the cells into a host animal.
What's most important to consumers is the product.Your clone is a twin of your former pet，but it won't necessarily look or act like the original.They may have different colors and you don't get your money back.Even the companies admitted in New York Times "You can clone the look of a dog，but you can't clone the soul."
（1）Why did the author mention Dolly the sheep？
A．To ensure the safety of cloning.
B．To show that it is easy to clone sheep.
C．To prove the technology has a long history.
D．To tell readers the method used to clone their pets.
（2）What can we know about cloning a pet？
A．Your pet can be brought back to life.
B．The charge of pet cloning is ﹩1-2000.
C．Your new pet will have a parent when cloned.

（3）What do the companies' words in the last paragraph mean？
A．Cloning is a moral issue.
B．The future of cloning is unclear.
C．The technology of cloning is not perfect.
D．Yon won't get the exact copy of the former one.
（4）Where is the text most likely from？
