Global warming will significantly increase the frequency of lightning strikes, according to a US research.

The research, published in Science, was carried out with the help of data from a US network of lightning detectors. The teams says they have calculated how much each extra degree in temperature will raise the frequency of lightning. "For every two lightning strikes in 2000, there will be three lightning strikes in 2100," said David Romps, at the University of California, Berkeley.

As well as triggering more wild fires, he said, this would alter the chemistry of the atmosphere.

The team's work reveals a new method of working out the relationship between temperature and lightning storms, by estimating the heat energy available to "fuel" storm clouds. "As the planet warms, there will be more of this fuel around, so when thunderstorms get triggered, they will be more energetic," said Prof Romps.

He and his colleagues calculated that every 1℃ rise in global temperature would lead to an increase in the frequency of lightning strikes by 12%.

They validated their calculations against a year of data from the US National Lightning Detector Network, which detects an electromagnetic pulse every time lightning strikes in the US. "The resulting data is exquisite," said Dr Romps. "The position and time of every lightning strike is very accurately recorded."

As well as triggering half of the wildfires in the US, each lightning strike— a powerful electrical discharge— sparks a chemical reaction that produces a "puff" of greenhouse gases called nitrogen oxides." Lightning is the

dominant source of nitrogen oxides in the middle and upper troposphere（对流层）," said Prof Romps.

And by controlling this gas, it indirectly regulates other greenhouse gases including ozone and methane. Prof Romps said that this was an example of a large response to "what sounds like only a few degrees of warming".

A scientist at the UK Met Office said it was important to understand future lightning patterns, but cautioned that there were still uncertainties in the researchers' model that needed to be tested further. The Met Office added that the application of this forecast to other parts of the world could be limited by the fact that rainfall patterns were very uncertain in many regions.

【1】The best title for the passage should be .

A. Global warming causes more wildfires

B. A new research on the effects of global warming

C. Climate change will make lightning strike more

D. The relationship between temperature and lightning

【2】According to Prof. Romps, .

A. it remains to be seen whether the lightning will trigger wildfires

B. the research is working out the causes of the wildfires

C. they detected an electromagnetic pulse every time lightning strikes in the US

D. lightning plays a major role in creating nitrogen oxides in the middle and upper troposphere

【3】What did the UK Met Office think of the result of the research?

A. The researchers’ model was not convincing enough.

B. The rainfall patterns stayed stable in many areas over a long time.

C. The result wouldn’t be applied to other parts/span> of the world.

D. No research would be needed to make sure of the result.

I recently heard a story about a famous research scientist who had made several very important medical breakthroughs. A newspaper reporter him why he was able to be so much more than the average person. What set him so far apart from others?

He that it all came from an experience with his mother that occurred when he was about two years old. He had been trying to remove a bottle of milk from the refrigerator when he dropped the slippery bottle, spilling its all over the kitchen floor—a real sea of milk!

When his mother came into the kitchen，instead of at him, giving him a lecture or punishing him, she said, “Robert, what a great and mess you have made! I have seen such a huge pool of milk. Well, the has already been done. Would you like to get down and play in the milk for a few minutes before we clean it up？”

Indeed, the boy did. After a few minutes, his mother said, “You know, Robert, you make a mess like this, eventually you have to clean it up and everything to its proper order. How would you like to do that? We could use a sponge(海绵)，a towel or a mop. Which do you prefer？” He chose the sponge and together they up the spilled milk.

His mother then said，“You know，what we have here is a failed experiment in how to carry a big milk bottle with two hands. Let's go out in/span> the back yard and fill the bottle with water and see if you can a way to carry it without dropping it. ”The little boy learned that if he grasped the bottle at the near the lip with both hands, he could make it. What a wonderful !

This scientist then remarked it was at that moment that he knew he didn’t need to be to make mistakes. Instead, he knew that mistakes were just for learning something new, which is, after all, what scientific are all about．Even if the experiment “doesn’t work”, we usually something valuable.
