When NASA astronaut Scott Kelly completes his yearlong mission on the International Space Station next year, he’ll come back just a little bit younger than his twin, Mark, than he was before. This is because time travels more slowly in space, a phenomenon first described by Albert Einstein’s 1915 theory of general relativity.

This December, universities and academies around the world are celebrating the 100th anniversary of the theory’s publication.

Even 60 years after his death, Einstein is still the most important scientist of the modern era. Looking back as far as 2,400 years ago, only Newton, Galileo and Aristotle were his equals.

Born in the era of horse-drawn carriages, his ideas started a technological revolution that brought about more change in one century than in the 2,000 years before.

In 1905, Einstein published four important scientific papers. These completely changed people’s ideas about space, time, light and matter. In one of these papers Einstein. introduced his theory of special relativity. Two groundbreaking parts of the theory were about the relationship between mass and energy and the speed of light. Einstein was able to show that mass and energy were connected through the formula E＝MC2. The theory also says that no object can travel faster than the speed of light.

About 10 years later came his theory of general relativity, the theory that modern physics is really based on. In Einstein’s mathematics, space has three dimensions, and the fourth dimension is time. Space and time are part of one continuum, called space-time. The presence of mass changes space-time, which explains where gravity comes from.

Computers, satellites, telecommunication, lasers, television and nuclear power, many of the biggest developments in the modern world, can be linked to Einstein’s work.

“We are a different people than we were a century ago,” said astrophysicist Michael Shara of the American Museum of Natural. History, “completely different, because of Einstein.”

However, there’s more to him beyond the image of a science mastermind. Einstein, as a person, has also become a grandfatherly icon in our culture.

He liked playing Mozart on his Violin and keeping fit by hiking and walking. Power was not his goal. In 1952, the young nation of Israel asked Einstein to be its president, but he refused.

And, yes, he was eccentric. With hair like that, how could he not be?

1.The first paragraph was written to 　　　　　 .

A. get readers to wonder about the effects of space travel on astronauts’ health

B. interest readers in the relationship between time and space

C. describe what gave Einstein the inspiration for his theories

D. lead in to the topic of the theory of general relativity

2.From the article, it can be concluded that 　　　　　 .

A. the theory of general relativity is mainly about space and time

B. the theory of general relativity proves that the speed of light is the fastest of all speeds

C. the theory of general relativity is about math and has nothing to do with physics

D. the most important parts of the theory of special relativity are about space and energy

3.By using Michael Shara’s words, the author intends to 　　　　　 .

A. give high praise to Einstein’s important publications

B. stress the great contribution that Einstein made to the modern world

C. suggest that more research needs to be done into Einstein and his work

D. say that there was more to Einstein than just being a science genius

In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution. It prevents our view of some of life’s most striking sights: stars, planets, and even galaxies.

“When I was a little boy, I loved the night sky. I remember looking up and the sky was filled with stars. I became an astronomer because I was amazed by their beauty,” says Robert gent, “Now in most big cities kids can’t see the stars like I did.”

Normally, about 2,500 individual stars are visible to the naked eye without using any special equipment. But because of light pollution, you actually see just 200 to 300 and fewer than a dozen from some cities. Only one in three Americans can see our own galaxy (星系) with the naked eye. Those people live far away from the lights of big cities, office building, and shopping malls.

Fortunately, there’s an inexpensive and useful way. If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save big amounts of energy and keep the beauty of the night skies. Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating much light pollution.

Light pollution affects more than our view of the heavens and can harm wildlife. Migrating (迁移) birds sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health. For all these reasons, researchers are working on ways to use light only when and where they are truly needed. Everyone deserves to look up at the sky.

1.According to the text, using our naked eyes, ______________.

2.Many cities and towns have passed laws limiting lights at night mainly to _________.

3.In how many ways will the light pollution do harm?

4.The underlined word “exhaustion” in the last paragraph means “_________”.
