But do you know it took men millions of years to be able to think this way?In fact,one of the most difficult things to teach children is the idea of numbers. In ancient times when a man wanted to tell how many animals he owned,he had no system of numbers to use.He put a stone into a bag for each animal.The more animals,the more stones he had.It may explain why the word“calculate”comes from the Latin word“calculus”.“Calculus”means“stone'”. Then,man used lines to count.People would just draw a line for each thing they wanted to count,but they had no word to tell the number. Later on,people used fingers.Again,we have the word that goes back to this.The word "digit" comes from the Latin word“digitus'”.It means“finger'”！And the fact that we have 10 fingers led to the use of 10 in the system of numbers. The number system we use today was invented by the Hindus in India thousands of years ago and was brought to Europe during 8th to 11th century by Arab traders ()In this system,people count things with ten numbers:1,2,3,4,5,6,7,8,9 and 0.It is decimal system,that is,it is built on the base of 10. ()1.How many ways of counting things are introduced to us in the passage? A.One. B.Two. C.Three. D.Four. ( )2.If A and B each drew four lines to count their own sheep,how many sheep did they have together? A.Four. B.Six. C.Eight.

C.Because we have no word to tell the number. D.Because we have no system of numbers to use. )4.What does "decimal system"mean in the last paragraph?

C.Simple counting methods firstly led to written numerals. D.Scientists think those lines show how ancient people used numbers. 3E.But the origins of numbering systems remain unknown. F.They likely counted single items by making marks on bones or sticks. One plus one equals two.There are 60 seconds in one minute.Sixty minutes equals one hour.There are 24 hours in one day.1.These basic number facts are part of our daily lives.But have you ever wondered how numbers first appeared and evolved throughout human history? It's certain that human civilization couldn't have progressed without numbers.2. That's because early counting methods left no written records.Archaeologists (believe counting began with simple quantities-probably starting with the concept of "one",though ancient people didn't use the word we know today.3. The most famous early counting tool is the Ishango Bone（伊尚戈骨)，discovered in Africa in 1960. This 20,000-year-old bone contains series of carved lines that resemble modern tally marks.4.And they suggest early understanding of basic mathematics.Some scientists believe the Ishango people might have even tracked lunar cycles using these bones. From these humble beginnings,numbers gradually developed into the complex systems we use today 5.Then they advanced to mathematics that built our modern world.The journey from bone carvings to computers shows how important numbers are to human progress. ●>39《●《高效课觉宝典川练》·英语·八年级上册（护教版》 3.prize title奖项勋章 12.To realize 4.(1)spend one's life doing...win awards for... 就课时过关月 inspire future generations set a new world record -、l.golden/gold 2.unwise 3.promised make great contributions to... 4.realize 5.thought 6.correctly (2)在…领域取得突破被视为… 7.hesitation 8.wonderful 9.replied 使数百万人受益献身于…作为榜样 10.challenging 二、l.a Chinese scientist 二、1.realize 2.rest 3.quantity/amount 2.is best known for which changed 4.double 5.chessboard 6.wise 3.received was called 7.promised 8.replied 9.hesitation 三、spent his whole life such as 10.ordered changed the way people lived had been used 三、1-5 BACDA 6-10 BCBDA awards was called 课时2阅读 四、 Xu Fengcan was born in October,1999 in Zhejiang. 〔课时精进月 She has showed great interest in space since she was a little 1.(1)is/was (2)are/were girl.She joined the army in 2017 and trained really hard. 2.(1)is (2)If you know the answer Because of her wonderful performance,she got the chance 3.(1)Wouldn't you like (2)instead and became the first female pilot for a solo flight in the PLA 4.(1)There isn't enough milk in the fridge. in2021.
