高中英語(yǔ)閱讀理解100篇:lightning

In earliest times, men considered lightning to be one of the great mysteries (神秘的事物) of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (燈泡).

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 (避雷針). This device (裝置物) protects buildings from being damaged by lightning.

Modern science has discovered that one stroke (閃擊) of lightning has a voltage (電壓) of more than 15 million volts (伏特). A flash of lightning 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 judge 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 (平均數(shù)) 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 tress. 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.

最早的時(shí)候，男人認(rèn)為閃電是一個(gè)偉大的奧秘(神秘的事物)自然。一些古人認(rèn)為閃電和雷聲是武器(武器)的神。

在現(xiàn)實(shí)中，閃電是電流在高空形成。一個(gè)閃電，長(zhǎng)1.6公里，有足夠的電力一百萬個(gè)燈泡(燈泡)。

美國(guó)的科學(xué)家和政治家，本杰明富蘭克林，是顯示在1752電和閃電之間的聯(lián)系的第一。在同一年，他還建造了第一個(gè)避雷針(避雷針)。這個(gè)裝置(裝置物)保護(hù)建筑物免遭雷擊破壞。

現(xiàn)代科學(xué)已經(jīng)發(fā)現(xiàn)一個(gè)沖程(閃擊)閃電(電壓)具有電壓超過15000000伏(伏特)。一個(gè)閃光的云層和地面之間的閃電可能長(zhǎng)達(dá)13公里，并以每秒30000000米的速度旅行。

科學(xué)家們認(rèn)為，大約有2000000000的閃電每年。閃電擊中帝國(guó)大廈在紐約市每年30到48次。僅在美國(guó)就導(dǎo)致平均(平均數(shù))每天一人。

是電風(fēng)暴的情況下最安全的地方是在一個(gè)封閉的車。外面，一個(gè)應(yīng)該去低接地和不到樹下。同時(shí)，應(yīng)遠(yuǎn)離水和金屬柵欄。在家里，人們應(yīng)該避免敞開的門口和窗戶，不要觸摸電線或金屬的東西。

閃電，它是更好的安全比遺憾?
