How do we know the time？ A clock，a watch or a cell phone can help us． However many years ago there were no clocks and knowing the time was not so easy． Over the centuries people have developed different w（1） of telling the time．
About 5，500years ago， the Egyptians i（2） the sun clock． This was a tall stone structure． Its shadow （影子）showed the movement of the s（3） they were able to determine（测定）midday．
About 3，500years ago，the Egyptians made a sundial． It was smaller than the sun clock and could measure （测量）the time for half a day． On c（4） days or at night it was impossible to tell the time with a sun clock or a sundial．
Water clocks were the f（5） clocks not to use the sun． The idea is simple． Water flows（流动） from one container（容器）to another． When the water reaches a certain l（6） it moves a lever （控制杆）and this shows the hours． The Egyptians used water clocks about 3，400years ago． These clocks were popular in the Middle East and China but they f （7） to keep accurate（精确的）time．
In the 13th century，the mechanical clock was invented． This was more accurate， b（8） was expensive to make． Over the next few centuries it was developed． For example， springs（发条）were added around 1500． This i（9） accuracy and allowed clocks to be smaller．
In 1927， the first quartz clock was developed． Clocks became cheaper to build and own． People began depending on them more and more to2 run businesses， markets and so on．
More recently， in1956， came the digital clock． And nowadays satellites（人造卫星）send our cell phones the time to the exact second． There has been a lot of progress in timekeeping but some things never c（10） ． Man of us still have trouble getting out of bed on time and not missing appointments．
Albert Einstein（1879﹣1955）
Early Life
Albert Einstein was born on I4th March，1879 in Germany． He was an extraordinary （非凡的）person since he was born． Einstein wasn't able to speak a word until three． He was curious（好奇的）and imaginative． He loved watching things carefully and asked a lot of questions about them．His questions were often hard to answer for teachers．
Schooling
Einstein started school in 1885． Though he did well in maths and science， he failed in many subjects like history ，geography and languages． He was not the teacher's favourite． He didn't enjoy going to school． Einstein finished high school in Switzerland and entered a university in Zurich． He graduated（大学毕业）as a teacher of maths and physics in1900．
Scientific Work
After graduation， Einstein worked at the Patent Office． He spent much time studying physics． By 1909， Einstein had become a top scientist． Though he became successful in the field of science， he still put great effort in scientific research． Finally， he won the Nobel Prize for physics in 1921．
Later life
Einstein kept at his research until he died in 1955． Scientists studied his brain（脑）after his death to see if there was anything special about it． However ，there was no conclusion（结论）．
Today， many famous scientists still think Einstein is the smartest man in the world．
