Astronomers have captured(捕获) the first direct image of a planet being born.

Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.

The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.

Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.

Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.

Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.

Planets can change orbits(轨道) after forming, so it’s difficult to answer such questions by studying older planets.

“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.

Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮强过) them. Kraus and Ireland used two techniques to overcome this problem.

One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.

The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.

1.The research on younger planets helps scientists _____________.

C. They are generally too small.           D. They rarely form.

3.According to the text, Kraus and Ireland _____________.

A. have been working in the same university

B. observed the planet on a volcano in Hawaii

C. used two new methods in the observation

D. cut holes in the mirrors when observing

4.Which of the following would be the best title for the text?

    Ball Management

Players should always keep a tennis ball in their hand or pocket during a match. Even the most patient tennis players despise waiting for their opponent to find a ball to serve(发球).

Behavior & Attitude

Even if you’re playing badly, you should not shout or look depressed in a friendly match. Undoubtedly, your attitude affects how you play, so try to have fun and stay positive.

Pace

Do not deliberately slow the game down. Play at the pace of the server and look ready. Servers also should not rush to start each point. You should re-do the point if you serve the ball before the receiver is ready. The receiver is out of luck, however, if he claims he was not ready after making an attempt at returning the serve.

For Spetators(观众)

Cheering

While it is seen as proper etiquette(礼仪）to remain silent during the live play, loud and spirited cheers are welcome after a hard-earned point. The players appreciate the recognition for their efforts and are encouraged to continue playing at a high level when the crowd is actively involved.

Leaving and returning to your seat

During live play it’s expected that all spectators will remain seated until the next break between games. Movements in the stands(看台) can serve as a distraction(分心的事物) to the players and can also block the view of other audience.

Photography

The issue of camera shutter(快门) noise has earned a lot of attention in golf, but luckily for tennis fans it’s much less of a concern on the court. While the noise produced by the camera is not seen as a major issue, flash photography should be avoided during live play.

1.During warm-ups, tennis player ______________.

A. ought to hit a full pace

B. can place their shots anywhere

C. should not practice competitively

D. had better run around the whole court

2.According to the text, during tennis matches, _____________________.

A. players can slow the game down when tired

B. players don’t have to keep a ball in their hand

C. the receiver shouldn’t return the serve if not ready

D. loud cheers are not allowed even after hard-earned points

3.It can be inferred from the last paragraph that ____________________.

A. flash photography is acceptable on the golf court

B. tennis fans can use flash photography during matches

C. the noise from cameras is not permitted in tennis matches

D. tennis matches require a less degree of quiet than golf ones

4.What’s the text mainly about?

A. Some tips for tennis players to win a match.

B. What to do while watching tennis matches.

C. How to behave properly in tennis matches.

D. Rules tennis players must obey in matches.

Have you ever wondered: What drives successful people? Take a look around and talk to your friends and seniors who are very successful, you will see all of them have adopted certain values which have proved vital for their success.

It is evident that successful people take initiative (主动性). When they find something needs to be done, they just do it instead of waiting. They believe that responsibility is taken, not given. They weigh immediately what has to be done and then do it with pleasure, thus strengthening their reputation.

Successful people are enthusiastic about the things they do, especially when they believe in what they are doing. They are motivated by their own satisfaction and the joy they get from doing their work. They work hard even when no one is watching and they throw themselves into their work.

They do not fear failure. Failures and disappointments in life are unavoidable. It is failure that teaches us much more than success. Successful people pick themselves up after a fall and try again with more determination and commitment and learn from each failure. They associate with those they can learn from and enjoy the company of those who appreciate their achievement.

    Having good IQ often gets a person what he wants but it’s really the EQ that keeps him there and helps him enjoy a high reputation. Successful people are polite to everyone and treat others with respect. By giving respect to others, they command respect for themselves.

Another important quality of successful persons is that they never complain. It’s better to praise others and win favor with them. So instead of complaining about a situation, successful people always try to solve it.

To put it shortly, take initiative and be enthusiastic about them. Do not be afraid to fail, but get up and start again. When you do so, success will be just around the corner.
