【题目】MOST of you may have heard about the Nobel Prize. But do you know the Ig Nobel Prize (搞笑诺贝尔奖)?The awards are given each year to 10 unusual achievements in science. It is to “honor achievements that first make people laugh, and then make them think.

This September the 2014 winners of the Ig Nobel awards came out! Research into why bananas are slippery(滑的) won the Ig Nobel for physics.

A team of scientists from Japan, tested 12 different banana skins. They then used sensors to measure the friction(摩擦力) between the slippery side of banana skin and the ground. They found that when someone steps on a banana skin, a special chemical, polysaccharide follicular gel(囊泡多糖凝胶), is set off. This chemical reduces friction by one-fifth. Later, scientists also compared banana skin with apple skin and orange skin and showed why apple and orange skins are not quite so dangerous. Friction was about 60 per cent higher on an apple peel.

Polysaccharide follicular gel is also found in the membranes (薄膜) where our bones meet. “This idea will help to design a joint prosthesis (人工关节),” Kiyoshi Mabuchi, the lead scientist, told the BBC news.

The Ig Nobel Prize in Medicine went to doctors from the Detroit Medical Center, US. They used salt pork to stop a young child’s nose bleed. Other interesting research includes whether owning a cat was bad for your mental health and looking at ugly art can be painful.

While Ig Nobel Prizes are mostly funny, great scientific breakthroughs(突破) can be made. In 2006, a team found that a type of mosquito(蚊子) is equally attracted to the smell of feet and cheese. As a result, mosquito traps were made using cheese to fight against malaria in Africa.

【题目】根据短文内容,将方框里A—E五个句子分别填入空缺处,使内容完整。

Everyone wants to be good-looking. We usually worry too much about how we look. Then how important is our appearance? 【1 Do you think beautiful people are always happier people?

2 Because some people may be more interested in looking at you than talking to you. They think of you as a picture rather than a person. There are also some people who think that women who are exceptionally(格外地) pretty and men who are particularly handsome must be stupid.3 .

4 No one wants to have a face that even his mother doesn’t want to look at. As a matter of fact, most of the people are plain----that is, to be neither attractive nor unattractive, and have a face that is easily forgotten.

Then maybe the best thing is not to worry too much about how you look, but simply try to be an interesting person. For interesting people are almost always attractive and unforgettable. 5 It can help you find happiness.
