     What will you be doing when you are 26 years o1d? Studying at university or working for a living? Take

a look at what Albert Einstein was doing at the age of 26.

    100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or

help, he wrote five papers (论文) for a physics magazine. Three of these greatly changed the study of

physics and our understanding of space, time, light and matter (物质). His most famous work is on the

Theory of Relativity (相对论). Einstein was given the Nobel Prize (诺贝尔奖) for it is discoveries. Although

he did many other things later, 1905 has been called Einstein's "Year of Wonders (奇迹)". It has been 100

years since then. Because of this, the UN has named 2005 me World Year Of Physics.

     Fifty years after Einstein's death, a question is asked, "Will there ever be another Einstein?" It may take a

1ong time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist.

Besides, physics is a different field (领域) now, and education is different, too. Even if you can't be the

next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought

independently (独立地) and read widely. He left us with a formula (公式) for life: If A is a success in life,

men A=X+Y+Z.X is work; Y is play; and Z iskeeping your mouth shut.

1. What was the field of Einstein's study? [ ]

A. Physics.

B. Wonders

C. Success in life.

D. Relativity.

2. The year 1905 is known as Einstein's "Year of Wonders'' because _____. [ ]

A. Einstein was working in Switzerland in 1905

B. Einstein was 26 years old in l905

C. Einstein made some very important discoveries in 1905

D. Einstein studied physics in l 905

3. Why hasn't there been another scientist as great as Einstein? [ ]

A. Because the study of physics is not enough.

B.  Because it is hard to make important discoveries as Einstein did.

C. Because people don't work hard any more.

D. Because physics is getting more and more difficult. 

4. The UN has named 2005 me World Year of Physics because _____.  [ ]

A. Einstein is 100 years old this year

B. Einstein has been dead for 50 years

C. There have been other great discoveries after Einstein's death

D. 1905 has been called Einstein's "Year of Wonders"

5. What does Einstein's formula of success mean? [ ]
