During the Spring and Autumn Period (770 BC-476 BC),Prince Chong'er of Jin had to leave his home.He 3 where to go and wanted to travel to other states.When he got to the state of Chu,King Chengwang gave him a big feast.The king 4 Chong'er with a question,"If you become the ruler of Jin, how will you thank me?” Chong'er thought for a moment."Your state has so many good things,"he said."I have nothing special.But the king still wanted a(n)5 answer.Finally,Chong'er said without 6,"If our armies fight,I'll ask my soldiers to retreat (sanshe."The king agreed and smiled. Years later,Chong'er returned to Jin and became King Wengong.Both states wanted to be stronger,so they went to war.King Wengong didn't break his 7-he ordered a retreat to Chengpu,sanshe away. The Chu soldiers thought Jin was afraid and 8 them.Suddenly,Jin's army surrounded (them! In the end,Jin won the famous Battle of Chengpu. Today,tuibi sanshe 9 stepping back to avoid a fight.It's a story where a promise counts,and "sanshe"isn't just a number-it's a way of solving problems 10 ( )1.A.stood out B.stood for C.stood up D.stood by ( )2.A.problem B.decision C.proverb D.idiom )3.A.doubled B.wondered C.knew D.understood )4.A.invited B.suggested C.challenged D.advised )5.A.right B.proper C.exact D.happy )6.A.determination B.hesitation C.decision D.resolution )7.A.promise B.require C.trust D.need )8.A.met B.cheated C.followed D.caught )9.A.replaces B.represents C.presents D.remembers )10.A.wisely B.originally C.sharply D.currently 二、阅读理解。 Have you ever met a number that seems to "magically"return to itself?The number 1,089 is famous for a surprising mathematical trick that works almost every time.This trick is often used by maths teachers to show how numbers can behave in unexpected ways. Here is how the trick works.First,choose any three-digit number where the first and last digits are ●>27● 英语·八年级·上册(HU) different (for example,352).Then,reverse (the digits to form another number(253).Subtract the smaller number from the larger one (352-253=99).If the result is only two digits,add a zero in front to make it a three-digit number (099).Next,reverse this new number (990)and add the two numbers together (099+990).The final sum will always be 1,089! Why does this happen?The reason lies in the way place values work.When you subtract a number from its reverse,the middle digit always becomes 9,and the sum of the first and last digits is 9.This creates a special structure that leads to 1,089 every time.Mathematicians have studied this pattern for years,and it still surprises people who try it for the first time. What makes 1,089 even more interesting is that it works for almost all three-digit numbers,unless the first and last digits are the same (like 121 or 343).In those cases,the subtraction gives zero,and the trick fails.But for any other three-digit number,1,089 appears like magic. This simple trick not only amazes people but also helps students understand important ideas in maths, such as place value,subtraction,and addition.Next time you want to surprise your friends,try the 1,089 trick一it never gets old！ ()1.What is the first step to perform the 1,089 trick? A.Add a zero to a two-digit number. B.Reverse the digits of a three-digit number. C.Choose a three-digit number with different first and last digits. D.Subtract the smaller number from the larger number. )2.Why does the trick fail for numbers like 121? A.Because they are too small. B.Because the first and last digits are the same. C.Because they have a zero in the middle. D.Because they are not three-digit numbers. )3.According to the passage,what must you do if the subtraction result has only two digits? A.Start the trick over from the beginning. B.Add a zero in front to make it three digits. C.Reverse the two-digit number directly. D.Choose a different three-digit number. ()4.What can we know from the passage? A.The 1,089 trick works for all three-digit numbers. B.The 1,089 trick is too difficult for most students. C.The 1,089 trick can help teach important maths concepts. D.Mathematicians no longer find 1,089 interesting. ●>28● 第一部分基础课堂 )5.What is the main purpose of the passage? A.To explain how a number trick works. B.To prove that maths is too hard to learn. C.To encourage readers to become mathematicians. D.To compare different number tricks. 三、短文填空。 根据短文内容，从短文前的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。 A.They can only use numbers or letters instead. B.There are also superstitions (about some numbers in China. C.In Western countries,some people think the number 13 brings bad luck. D.It is interesting to see how Chinese people use numbers in different ways E.So instead,they used the hotline number-10010.com.This is easier to type and remember. F.Many couples choose to get married on May 20th for this reason Do you like the number 13?1.In the past,a lot of tall buildings didn't have the 13th floor. 2. For example,the number"4"is said to be unlucky because it sounds like the Chinese word for "death".But that's just one example about numbers in China. When I first came here,I was surprised to see that many websites had numbers in their names instead of letters.I soon found that this is actually convenient,as Chinese characters (cannot be used for website addresses.3. In pinyin,the telecom company China Unicom is called Zhongguo Liantong.If the company used their pinyin name for their website address,it would be quite long.4. In addition,the pronunciations of some numbers sound similar to other words in English.This is wordplay(双关语).For example,the numbers“S20”in English sound similar to the pronunciation of the Chinese phrase“I love you”.5. 四、信息匹配。 下面的材料A一F是关于数字知识的简介，请根据五名学生的研究兴趣，将其与对应的材料进行 匹配。 A.The number 9 has an amazing property.When you multiply 9 by any number from 1 to 10,the digits of the answer add up to 9.For example,9 x3=27 and 2+7=9.This works for 9 x1 to 9 x10. B.A googol is 1 followed by 100 zeros.It is a very large number.A internet company got its name from this number,but changed the spelling a little. C.Palindromic numbers read the same forwards and backwards.For example,121 reads the same both ways.Other examples include 343,1221,and 12321.They are like word palindromes such as "radar". ●>29● 英语·八年级·上册(HU) D.The Fibonacci sequence is a number pattern:0,1,1,2,3,5,8,13...Each number is the sum of the two before it.This pattern appears in nature,like in sunflowers,pinecones,and seashells. E.Perfect numbers equal the sum of their divisors ()excluding the number itself).The smallest perfect number is 6 because 1+2+3=6.The next is 28.These numbers are very rare. F.Prime numbers can only be divided by 1 and themselves.Examples include 2,3,5,7,11,and 13. They are called the "atoms"of mathematics because every other number is built from them. )1.Linda wants to find a number that reads the same forwards and backwards.Her maths teacher said these numbers are called palindromes.She wants an example. )2.Tony is curious about the number 9.He wants to know what special property it has when you multiply it by other numbers. )3.Sally heard that some numbers are called "perfect numbers".She wants to know the smallest perfect number and why it is special. )4.Ben is learning about the Fibonacci sequence.He wants to know where this number pattern appears in nature. )5.Anna wants to know what a "googol"is.She heard it is a very large number and that a famous company got its name from it. 五、语法填空。 Once upon a time,there was a detective (named Detective Maths.He was very good 1. solving maths problems and loved to help people with their calculations.One day,he received a letter from the Maths Kingdom.2. letter said that a number had gone missing in the kingdom.The king ordered Detective Maths 3. (help)his kingdom! Detective Maths packed 4.(he)notebook and pencil and set off.He soon arrived at the Maths Kingdom,a place filled with colourful numbers and friendly maths 5. (symbol).The king said,"Because of the missing number,all our calculations are wrong.I know you have the 6. (able)to solve this case(案件).” Detective Maths started investigating（调查)by7. (talk)to the numbers and symbols. He asked them if they had seen anything strange or unusual.They said no. Then Detective Maths 8. (check)all the calculations in the Kingdom.After working out many maths problems and puzzles 9. correct),Detective Maths finally found that the missing number was 5.He also discovered a number thief (hiding in a secret cave.The thief was a little number named Zero.Zero took away the missing number 10. he wanted to be the only number in the Maths Kingdom.Detective Maths told Zero that all numbers were important and that they needed to work together. ●>30●
