She was a poor girl who worked to get money to pay for her lessons. She became the famous woman scientist of her time. That's the story of Marie Curie's life. She didn't mind working and she didn't care about the honors(荣誉)that were given to her in later years.

Marie was born in 1867. Her name was Marie Sklosovska then. She lived in Poland. Her father was a teacher. Everyone soon saw that Marie had a quick mind.

Marie's mother died when her youngest daughter was only ten. From then on, Marie knew that she would have to work hard at her lessons if she wanted to be successful(成功的)in her life. She studied very hard and was one of the best students at her school.

Marie and her older sister, Bronya, wanted to study in France at the Sorbonne. But their father didn't have enough money to send them there. It was Marie who had an idea: she would teach at home and send her money to Bronya. After her sister finished studying in Paris, she would get work and send Marie the money to study there herself. So Marie worked very hard for six years to pay for her sister's studies. At last it was Marie's turn but when she got to France, her sister was married and could not give her much help.

Again Marie worked. She studied in a small room without heat or light. She lived on bread and tea most of the time. But all she thought of was her maths and science. This was her world.

After four years' hard work, Marie and her husband found something which was called radium(镭). They were given the Nobel Prize(诺贝尔奖)for their great discovery(发现). But they were too ill to go Stockholm themselves to receive it.

Marie always said that it was because of her children that she want her work. And she discovered a hidden power and gave it to the world. It was the same power, however, that killed Marie in 1934.

What to go on holiday, but don’t have enough money for luxury (豪华的) hotels and expensive trips? Backpacking might be right up your street.

Backpacking is a very cheap kind of travel. European and American students and young adults who may not have all that much money often do it. It is called backpacking because, instead of using a suitcase (手提箱), people put all their things in a large backpack. A backpack sits on your back, and you pack all your clothes inside.

The most popular places for backpacking are Southeast Asia and South America. These countries aren’t very expensive, and are also very hot for most of the year. India and Australia are also very popular. In 2002, over 400,000 backpackers hit Australia. Sometimes, backpacking can be dangerous. A British backpacker was recently shot dead at a beach party in Thailand, and every year similar things happen.

Backpacking, in fact, is much more than a holiday—for young people in Europe, it is seen as a way of learning about the world.

Backpackers often travel alone for many months, as this is seen as more of an adventure and challenge. Beyond finding new words, backpacking, people say, is all about “finding yourself”.

1.Is backpacking an expensive kind of travel?

2.Why is it called backpacking?

3.Where are the most popular places for backpacking?

4.How many backpackers traveled to Australia in 2002?

5.What do people think of backpacking?
