Do you know what makes lightning（闪电）？Why does lightning strike（击打）？
Lightning strikes happen when ice and water in clouds rub（摩擦）together， and cause atmospheric（大气层的）changes． When this happens， it creates a static charge（静电）．Lightning can strike inside the cloud， between two clouds or between a cloud and Earth． It's the last kind of strike that is the most dangerous for humans．
Lightning can be very dangerous． Every year， lightning kills people because it can start big fires or because it reaches a temperature of 28， 000 C． About l， 000people are hit by lightning every year in the United States， and about 100of them die as a result．
Lightning makes people shocked， and it happens all over the world! Scientists think that there are more than three million lightning strikes every day in the world﹣that's thirty strikes every second（秒）． An American mant Roy Sullivan， who worked in a park， survivedfrom the most lightning strikes． Between 1942and 1983， he was hit seven times! And he keeps the highest world record．
Lightning is sure not something to play with． When lightning strikes， it's best to stay inside a large building． To stay safe， do not stand under trees， on hills or near water． Also， do not lie down on the ground， or the electricity may go through you and cause a heart problem．

He thought it was pronounced just like the English word “sun”，so he said to the Chinese student, “ I see your name is sun. You are wanted here.”

One of the most famous scientists to study adaptations (适应能力) was Charles Darwin (达尔文). He was born in England in 1809. He wasn't the best student in his school, but when he was 16, his father sent him to a medical school. Charles liked spending time outdoors observing (观察) nature more than attending medical classes and dropped out(辍学) without graduating.
Next, Charles' father sent him to school to become a minister (牧师). This time he made it to graduation. But he didn't want to do the work of a minister. His friends encouraged him to follow his interest in science.
After graduation, Charles was invited to sail on the Beagle as an unpaid scientist. He wasn't the first choice, but he was the lucky one to go. The Beagle was to travel to South America and then around the world. The crew's task was to make maps of the places they visited.
On December 27th, 1831 Charles Darwin sailed from England on the Beagle. The trip was planned to last two years. In fact, it lasted five. During this time, he saw many amazing things. He collected lots of plants and animals and took them back to England to study.
Twenty-three years later, Darwin published a scientific paper with another man named Wallace. Darwin described how some animals have adaptations that help them survive.
