Do you think laughter can help you deal with pain? Scientists from Britain did two experiments. The first was done in a lab. People wore special wristbands*. Some of them were asked to watch comedies while others watched serious programs. Then the scientists tightened* the wristbands to see how much pain the people could feel.
The other test was done at an art festival. Some people watched a comedy show and others watched a drama*. At the same time, they had to put their backs against the wall and keep their legs bent* just like sitting on a chair. They did this before and after the show.
Scientists found that just 15 minutes of laughter improves people's ability to stand pain by 10%. However, the serious programs and the drama didn't make a difference to pain at all.
The study found that the magic power of laughter comes from endorphins*. These are chemicals*. They are produced by the human body. They make you feel less pain and can make people feel happier. Exercise can produce endorphins.Your muscles* move in and out when you are laughing. Scientists believe that this makes your muscles tiring, so we start to produce endorphins.
Scientists also found that the only real and relaxing laughter works not just polite laughter.
Next time you have a headache, get together with a group of Mends, watch a funny movie and laugh. You will soon feel a lot better because laughter is the best medicine.
( )33. Scientists knew how much pain the people felt by in the first experiment.

Tim Berners-Lee is not the most famous inventor in the world. However, his invention has changed our lives.
He was born in London, England in 1955. When he was a small boy, Tim was interested in playing with electrical things. He studied science at Oxford University. He made his first computer from an old television at the age of 21.
Tim started working on early computers. At that time, they were much bigger than now. He worked in England then Switzerland. Tim was really interested in two things, computers and how the brain works. How could the brain connect so many facts so quickly? He had to work with people all over the world. They shared information about computers. It was hard to manage all the information. He answered the same questions again and again, and it took much time. It was even difficult for computers in the same office in Switzerland to share information. Tim also forgot things easily. Could a computer work like a brain? Could it “talk” to other computers?
There was an Internet already but it was difficult to use. In 1989, Tim Berners-Lee invented the World Wide Web (WWW) all by himself. This had a special language that helped computers talk to each other on the Internet. When people wanted to share information with others, they used the World Wide Web. The Internet grew quickly after that.
Tim Berners-Lee doesn’t think he did anything special. He says that all of the ideas about the Internet were already there. All he did was to put them together. He says that many other people worked together to make the Internet what it is today.
Most inventors want to become rich. But Tim gave away the World Wide Web for nothing. He now works in America. He helps people share technology and wants the Internet to be free for everyone to use. Maybe he is the most important but least famous inventor in the world today!
( )36. What was Tim Berners-Lee interested in?
A. Looking for jobs in different cities. B. Talking to people around the world.
C. Studying how to connect computers. D. Exploring how to improve memory.
( )37. The underlined word “it” in Paragraph 3 refers to “ ”.
A. Working on early computers B. Connecting different facts together
C. Travelling to the office in Switzerland D. Repeating the answers to the same questions
( )38. What does the writer think of Tim Berners-Lee?
A. He is not famous because he is not rich.
B. He has changed our lives and he is great.
C. He did nothing special but make people a good life.
D. He has made great achievements in memory research.
40. Why is Tim Berners-Lee one of the most important men in the world?
