When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.

Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.

The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.

This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

When something goes wrong，it can be very satisfying to say，“Well, it’s so-and-so’s mistake.”or “I know I’m late，but it’s not my mistake；the car broke down.”It is probably not your mistake，but once you form the habit of blaming somebody or something else for a bad situation，you are a loser You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.

　Winners are good at dealing with problems. For example, if you were late because your car broke down, maybe you need to have your car checked more regularly. Or, you might start to carry the useful phone numbers with you, so you could call for help when in need. For another example, if your colleague(同事) causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t depend on the person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.

　　This is what being a winner is all about-creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose mistake it is.” Once you are confident about your power over bad situations, problems are just stepping stop on for success.

A. have responsible and able colleagues

B．blame him for his lack of responsibility

C．tell him to find the cause of the problem
