Once Wilhelm K. Roentgen and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube from which the air had been taken away. Then one day Roentgen noticed that though the tube was covered with black paper， some strange kinds of radiation （辐射） were coming through and making a screen nearby give out light. Roentgen could see nothing out of the tube. But then he discovered that if he put the screen in the next room on the other side of the closed door， the rays still seemed to affect it. The screen showed that the rays could pass not only through the black paper but also through wood.

The next thing he found out was that if he put his hands between the rays and a photographic plate， the rays would print a shadow of the bone framework of his hands on the plate. In fact， the rays could pass as easily through the fleshy （肉的） part of his hand as through the black paper， but hardly at all through the bone. So Roentgen made the first X-ray picture of a hand showing just how the bones in the hand fitted together.

Roentgen called these unknown rays X-rays， but other scientists called them Roentgen rays in honor of the man who first found them.

Most of the time， people wear hats to protect themselves from harsh weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays， hats， especially women's hats， are much more than that. More exactly， hats have changed into fashion and style symbols by many movie stars. What's more， people now consider many different features when choosing even a simple hat. Many designers point out that， when choosing the right hat， it's important to consider the color of your skin as well as your hair， your height， and the shape of your face.

First of all， the color of the hat should match the color of your skin and hair. For instance， black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair， one will look as attractive as a summer flower. Second， the height of the hat is also an important point. Tall women should not go for hats with tall crowns， just as short women should choose hats with upturned brims （帽檐） to give the look of height. Third， and most importantly， the shape of the face decides the kind of hat one should pick. A small， gentle hat that fits the head looks good on a small face. However， women with big， round faces should choose a different style.

As the saying goes， “Fine feathers make fine birds.” A good hat can not only help your dress but also support your features， so why not choose the best possible one next time you want to be in public？4.What does the underlined word “harsh” in Paragraph 1 probably mean？

Science Hero： Jules Verne

科学英雄：儒勒 · 凡尔纳

儒勒·凡尔纳（ Jules Verne ，1828年2月8日—1905年3月24日），法国小说家、博物学家，现代科幻小说的重要开创者之一。他一生写了六十多部科幻小说，总题为《在已知和未知的世界漫游》。他因其大量著作和突出贡献，被誉为“科幻小说之父”。

As a science fiction writer， Jules Verne is our hero. Jules Verne was born in France in 1828 and originally studied to be a lawyer. But he was fascinated with the exploration of nature and the world. Also， he loved writing. In his writing he was able to bring scientific ideas to a general audience. If he were alive today， he'd probably be writing for us.

Jules Verne also wanted to challenge people to think about new things that science could bring them. His stories were full of fantastic machines， but they were always things that could in principle be constructed. Because of this combination of knowledge and imagination， he was able to anticipate many things that now actually exist.

For example， you may know that in his novel Twenty Thousand Leagues Under the Sea， Verne imagined an enclosed boat that could travel underwater—what we now call a submarine. But did you know that on board his submarine he put another imaginary device， the electric stove？ Or that he was one of the first to suggest putting people inside a giant bullet and firing it at the moon？ That's not quite how we got there， but the principle is much the same.

作为一名科幻小说作者，儒勒·凡尔纳是我们的英雄。他于1828年出生在法国，起初他是学习法律的。但他对探索自然和世界十分着迷，而且他喜欢写作。在他的作品中，他能将科学概念带给读者。如果他还活着，他很可能还在为我们创作。

儒勒·凡尔纳也想挑战人们去思考科学可能带给他们的新事物。他的故事中充满奇妙的机器，但都總是理论上可以创造出来的东西。由于知识和想象力的结合，他预见了很多现在确实存在的事物。

比如，在凡尔纳的《海底两万里》中，你可能知道他设想了一艘可以在海底穿梭的船——我们现在称之为潜水艇。但你知道在其潜水艇上，他放置了另一件想象的工具——电炉吗？或者说他是第一个建议把人放在巨型炮弹里，瞄准月球发射的人之一吗？虽然我们并不是那样登上月球的，但理论上大致相同。
