About 2,500 years ago,people in Rome used their hands to count.In Roman numerals,two fingers means 2,three fingers means 3,you can keep your four fingers close on one side and your thumb on the other side.If you want to say five,you can keep your four fingers close on one side and your 带条 thumb on the other side.Make each of your hands be five,then you'll have ten.So in Rome,the numbers are“L,Ⅱ，Ⅲ，V,V,I,I,Il,X,X”.Also,“L”means fifty,“D”means five hundred and "M"means one thousand.But there is no zero in Rome numerals.Today,few people use them because they are difficult to write and count.But we can still see them on some watches and clocks. Today,most people use the Arabic numerals.They are easy to remember and write.They help people to count things every day.In fact,Indians first created and used the Arabic numerals.In the 训挺 late 8th century,people in Arabic countries learned about them.Then the Arabic people took them into Europe.So people in Europe called them Arabic numerals.Today,people around the world use Arabic numerals and they help a lot. 箭 )1.Which of the following means five in Roman numerals?

For example,the word for number 8 sounds like "making lots of money"in Chinese.So,people think it a very lucky number.Some people will even spend much more money to have 8s in their phone numbers.Do you remember the Summer Olympic Games in Beijing?It opened at 8:08 p.m.on August 8,2008. The number 9 is also a lucky number because of its connection to the emperors (of China. There were nine dragons on emperors'robes (and it's told in many Chinese ancient stories that the dragon has nine children.The number of 9 also means "long lasting".In China,a man would send 99 or 999 roses to his lover with the wishes that the love between them will be long lasting. What's more,Chinese think that the number 2 is lucky as it's said that "all good things come in pairs”.For example,during wedding celebrations（婚礼庆典)，you usually find pairs of red candles, double pillows and many other things in pairs.And people often give gifts in pairs for someone's birthday,wedding or other celebrations.

()5.From the article,we can learn that some people would pay much more money for A.the phone numbers with 8s B.the Summer Olympic Games C.the emperors'robes D.the wedding celebrations ()6.Why would a man like to send 99 roses to his lover? A.Because he thinks that women love roses the best. B.Because the number 9 has a connection to the emperors of China. C.Because he hopes that he will be in love with the woman for a long time. D.Because he wishes that he will have lots of children with the woman in the future. ()7.What can we learn from the article? A.The shape of a word makes Chinese think that a word is lucky or unlucky. B.The Beijing Olympic Games opened at 8:00 p.m.on August 8,2008. C.Chinese like to give gifts in pairs. D.Roses mean long lasting in Chinese. ()8.What is the article about?

Almost all human brains have a problem dealing with big numbers.In ancient times,early humans had no need to develop such a skill.They only needed to understand small numbers,like the number of people in the their family,or how many animals they had caught.So there's no need to tell the difference between large and very large. One way is to turn big numbers into something you know.For example,if imagining 400,000 people is too hard,you can think that a soccer playground usually can hold around 40,000 ·11· people.Then 400,000 people mean 10 soccer playgrounds of people.Or if you have 1,000 yuan,then a millionaire(百万富翁)hasl,O00 times more money than you. Although it is not necessary for us to understand larger numbers,we still can work out them and get useful answers. (）g.What might one“quetta”refer to? A.One followed by 30 zeros.

There is also a saying that came from the myth (of Northern Europe.12 gods attended the Havra banquet.During the banquet,an uninvited guest,Luo Qi,the god of worry and noise,suddenly came.The god Bolt was popular among other gods.The intrusion (of the 13th visitor led to ,12 Bolt's death.Therefore,13 has become the unluckiest number in the Western world. Westerners try their best not to use the number 13.In Netherlands,it is difficult to find the 13th house numbers.They replaced the 13th with "12A".You can't find the 13th rows and the 13th seats in British theaters.In addition,if the 13th day of a month is Friday,this Friday will be called Black Friday. )13.What's the relationship between Jesus and Judas?
