Throughout modern history, there has perhaps never been a scientist as iconic (标志性的) as Stephen Hawking.
On March 14, the British physicist passed away at his home in Cambridge, England. Since then, many people have expressed their condolences on social media. Whether be was educating the world with his knowledge of the universe, or making fun of himself in TV shows like The Simpsons, it's hard to imagine what the world will be like now Hawking is no longer in it.
Hawking was an icon for many reasons, but he will be best remembered for his work in the field of science. Building on German scientist Albert Einstein's work. Hawking explained his belief that space started with the Big Bang, and will end with black holes. This proposal kicked off a series of investigations, including into the origin of the universe itself. "This complex set of law can give us the answers to questions like how did the universe begin," Hawking wrote in his 2010 work The Grand Design. "Where is it going and will it have an end? If so, how will it end?"
His work in science abide, he also managed to overcome many difficulties in his personal life. While studying for a postgraduate degree in cosmology at Cambridge University, he was diagnosed with motor neurone disease at the age of 21. His illness left him paralyzed and he was told he only had a short time to live. However, he went on to become one of the greatest minds the world has ever known. "I felt it was very unfair — why should this happen to me," he wrote in his 2013 memoir. "At the time, I thought my life was over and that I would never realize the potential I felt I had. But now, 50 years later, I can he quietly satisfied with my life."
Hawking leaves behind a great legacy. His signature book A Brief History of Time: From the Big Bang to Black Holes published in 1988, became one of the world's best-selling science publications. He inky no longer be with us, but Hawking will continue to inspire the world for generations to come. As he once said himself, "Look up at the stars and not down at your feet."

Public Speaking Training
Get a coach
1., so get help. Since there are about a billion companies out there all ready to offer you public speaking training and courses, here are some things to look for when deciding the training that's right for you.
Focus on positives
Any training you do to become more effective at public speaking should always focus on the positive aspects of what you already do well. Nothing can hurt confidence more than being told that you aren't doing well. 2., so good public speaking training should develop those instead of telling you what you shouldn’t do.
3.
If you find a public speaking course that looks as though it’s going to give you lots of dos and don'ts, walk away! Your brain is so full of what you’re going to be talking about. 4.. As far as we’re concerned, there are basically no hard and fast rules about public speaking. Your audience can be your friends.
You are a special person not a clone.
Most importantly, good public speaking training should treat you as a special one, with your own personal habits. 5.. Your training course should help you bring out your personality, not try to turn you into someone you're not.
A. You aren’t like anybody else
B. You already do lots of things well
C. Turn your back on too many rules
D. Check the rules about dos and don’ts
E. Whatever the presentation, public speaking is tough.
F. The one thing you don’t want is for them to fall asleep
G. So trying to force a whole set of rules into it will just make things worse
Many scientists today are convinced that life exists elsewhere in the universe---life probably much like that on our own planet. They reason in the following way.
As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.
Life requires the right amount and kind of atmosphere. This eliminates(除去) all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it.
Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify.
Finally, life could evolve(进化) only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away.
If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.
This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.
1.The existence of life depends on all of the following factors EXCEPT .
A.the right amount of atmosphere B.our own solar system
C.steady heat and light D.the right distance from the sun
2.Which of the following statements is INCORRECT?
A.The planet must be as big and heavy as the earth.
B.Proper conditions are essential to the existence of life.
C.Double stars can provide steady light and heat.
D.The distance between a planet and its sun should be right.
3.What kind of planet might NOT support life?
A.Most of the planets of the stars. B.Stars similar to our sun.
C.Planets similar to the earth. D.Planets with proper conditions.
4.At the end of the passage the author suggests that .
A.it is impossible for life to exist on planets. B.earthlike life could only exist on a few planets.
C.life could exist on only one planet in a million. D.life could exist on a great number of planets.
