In earliest times, men considered lightning （闪电）to be one of the great mysteries（神密） of nature． Some ancient people believed that lightning and thunder were the weapons(武器) of the gods．
In reality lightning is a flow of electricity （电流）formed high above the earth． A single flash（闪烁） of lightning 1.6 kilometers long has enough electricity to light one million light bulbs．
The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752． In the same year he also built the first Lightning Rod (避雷针)． His device（发明物） protects buildings from being damaged by lightning．
Modern science has discovered that one stroke of lightning contains more than 15 million volts(伏特)． A spark（火花） between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second．Scientists estimate (估计) that there are about 2,000 million flashes of lightning per year． Lightning hits the Empire, State Building in New York City 30 to 48 times a year． In the United States alone it kills an average of one person every day．
The safest place to be in case of an electrical storm is in a closed car． Outside, one should go to low ground and not get under trees． Also, one should stay out of water and away from metal fences． Inside a house, people should avoid open doorways and windows and not touch wires or metal things．

查看习题详情和答案>>To the Editor,
I have been reading your newspaper, the Hometown Gazette, for the past two years, ever since I moved to Smithville. We moved here from New York City, so I am accustomed(习惯的) to reading excellent newspapers such as The New York Times . In fact, we still have the Times delivered on Sundays. The entire family enjoys reading the recipes（食谱） in the magazine, as well as the Styles section.
The Times is great, but the Gazette is another story. I’ve never read an article that doesn’t contain at least three or four spelling or grammatical errors. For instance, in last week’s issue you misspelled the word “secretary”, used a singular verb with a plural noun, and used “it’s” as a possessive (所有格). And that was just in the lead story! In case you never went to elementary school, “it’s” means “it is ”.It’s also a possessive adjective!
It’s a pity that this tiny little hick(乡下) town has only one newspaper, because I’d like to have an alternative(替换物) to the rag you publish. I find it hard to believe your news stories. If you can’t spell correctly. How can you get your facts right?
I’ve been meaning to get this off my chest for some time. Please cancel my subscription(订阅). And buy yourself a dictionary.
Sincerely,
Jane Z, Jones
