阅读下面的短文．并根据短文后的要求答题。

Since 1850．the temperature of Earth’s surface has increased about 0.6°C．Scientists predict it may warm much more by the end of this century．Who’s turning up the heat? Well, it seems that we are! Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to peoples actions．Over the past 150 years, we've added huge amounts of certain gases, especially carbon dioxide（CO2）to the air．These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe storms，floods and droughts．

We add carbon dioxide to the air when we burn things, especially fossil fuels．Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago．Coal，oil，and natural gas are all fossil fuels．People in the United States and other countries started bunting large amounts of fossil fuels more than a century ago．The amount d fossil fuels being burned each year has been increasing worldwide．The more we burn，_____________________．

What can we do to help? Nowadays to live a low-carbon life is quite popular in the world． Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words. In fact, even the simplest everyday activities can make our lives low-carbon．

1．What problem can global warming cause?（根据短文内容回答问题）

2．What are fossil fuels?（同上）

3．请将第一段中的划线句子翻译成汉语。

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.
