If your finger’s wrinkling up had no use at all, “ it wouldn’t need to.” Professor Tom Smulders from Newcastle University, UK, told BBC News. By studying wet fingers closely, Smulders and his partners found that the wrinkles looked a bit like the patterns on the car tire or on the bottom of the running shoes. So they made a guess that wrinkles on fingers might be able to help the hand hold things more tightly.
To test this, researchers asked 20 people to pick up marbles from water with their hands. But before they started, some of the people had to keep their hands in water for half an hour.
The researchers found that the people with wrinkled fingers completed the task the task faster than those with dry hands. But when they were asked to move dry marbles, all the people performed equally well, no matter they had the wrinkled fingers or not.
Our ancestors might not have played with marbles, but wrinkled fingers could have made it easier for them to climb around in the wet forests and catch fish from rivers, researchers say.
Similarly, our toes also get wrinkled in water. This may have developed from our ancestor’s need to run on wet ground.
But the question is, if wrinkled fingers are so helpful, why don’t our hands just stay that way all the time? Researchers explained that wrinkling has its disadvantage: wet fingertips are far less sensitive than smooth ones, reducing our sense of touch.

How important is music? When they are asked this question, students and parents usually answer that music is nice, but not very important. It is often considered only as entertainment, but not the first choice for education. This opinion is shortsighted. In fact, music education is necessary and important for all students.
Music tells us who we are. Music reflects the creators’ thinking and values, as well as the social environment it came from. For example, just as Mozart music represents a lifestyle, rock music represents a lifestyle, too. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions.
Music provides a kind of ability to know the world in a different way. Science explains how the sun rises and sets. Music explores the emotive meanings. We need every possible way to discover and response to our world because no one way can get it all.
Music is a form of thought, as powerful as science. It is a way we human beings “talk” to each other. Through the language we expresses our feelings, our discoveries, our ideas, our imagination and our hopes so that they can be shared with others. When we do not let our children receive good music education, we take away from them the meanings that music expresses. Science does not tell us what it means to be human. Music does.
So music education is much more necessary than people generally realize.

Some people believe that your nationality can influence your personality. This is why you might hear someone saying “She is a typical(典型的) Australian” or “He is so French”. It seems that people from a certain country share certain similar characteristics.
French
French people are often seen as romantic and outgoing people with a great love for life, food and wine. They are good at singing and dancing.
Chinese
Chinese are friendly people who are hard-working. They are polite because they are careful about “saving face” when dealing with other people.
Australians
Australians are merry people who spend a lot of time outdoors. They enjoy a slower life. They laugh a lot but sometimes people think they are loud and rude.
Germans
Germans are often described as being serious and careful. They are hard workers and pay a lot of attention to details. However, sometimes people say Germans have no sense of humour.
All these national types can be true for some people, but very wrong for others. For example, you might meet a German who is a confident singer with a great sense of humour, or an Australian who is shy and quiet!

Every year, wildfires(野火) destroy much forest land. homes are broken down, and thousands of people die. smokejumpers are stop helping to stop this.
Smokejumpers are a special kind of firefight. they jump from planes into areas that difficult to reach by car or on foot. they race to put out fires as fast as they can.
At a fire site, Smokejumpers first examine the land and decide how to fight the fire. their main goal is to stop fire from spreading. using basic tools such as shovels and axes, smokejumpers clear land of burnable material like plants and other dry material. they carry water with them too, but not much.
Although most smokejumpers are men, more women are joining. Most important are your weight and height. Smokejumpers in the U.S. for example ,must be 54 to 91 kilograms, so they don’t get hurt when they land, or get blown by strong winds.
Smokejumpers must be able to live in the wilderness. in Russia ,many smokejumpers know how to find food in the forest and even make simple furniture from trees.
They work is dangerous, the hours are long. But for these firefighters, smokejumpers isn’t just a job. They love being able to jump out of planes, fight fires, and live in the forest. As 28-year-old Russian smokejumpers Alexi Tishin says,“This is the best job for the strong and brave.”
小题1:What are Smokejumpers?
小题2:Where do the jump from?
小题3:What’s their main goal?
小题4:Why should they have proper weight?
小题5:What’s needed to be a smokejumpers?
