Both language and music play a huge role in our culture． Here are some of their similarities．
（1）Both language and music have a writing system．
In English we record language using letters． Similarly， we use notes to record music． Just as you are reading letters and find meaning in them， musicians read notes and create meaning in the form of music． So just as you read English， you can read music． By writing pieces of text or music， we are able to share experiences through time． I can read the ideas or hear the works of someone who lived hundreds of years ago， which is really exciting．
（2）
You can guess where someone is from by listening to the language they use．In the same way，styles of music are different around the world， giving us the chance to understand many different cultures， This also means that there is something for everyone! Even if you don't like British pop music， you may love the energy of Latin American salsa music．
（3）Both share feelings．
How do you know that I am angry？ Of course you can see it in my face， but you will know for sure through my words， Similarly， music can show you exactly how the composer （作曲者） was or is feeling． When I'm happy， I want to sing and dance to a happy song to celebrate my happiness； and I listen to slow and quiet music when I'm feeling down． I think we have all used music to express our feelings， often combining （结合）it with language in the form of song lyrics．
（1）Which of the following is the best for the blank？
A． Both are from daily life
B． Both bring us happiness
C． Both have a sound system
D． Both vary （变化） with culture．
（2）According to the passage， when the writer feels unhappy， he might listen to ．
A． scary movie music
B． exciting rock music
C． loud electronic music
D． sad piano music
（3）The underlined word "it" in the passage refers to " "．
A． music
B． idea
C． feeling
D． culture
（4）Which of the following is NOT TRUE according to the passage？
A． We use notes to write music．
B． We can write music if we speak English．
C． We can understand different cultures in music．
D． We can share the composer's feelings in his or her music．
Would you like to improve yourself？ Would you like to be a better person？ Good news! Here we've got some tips for you．
Tip 1Be Kind
Remember to be kind to yourself． You can do simple things to take care of yourself， like getting enough sleep to make yourself energetic． If you don't do like that， you will not bring anything good to anyone else． When you decide to show more kindness to yourself and to others， life changes quickly in a better way．
Tip 2Be Encouraging
It's amazing what a kind word or touch can do． When I was a kid， I went to a lot of schools． It always made me scared， and I was very nervous and unsure of myself． One time， a teacher touched my head and said， smiling， "Don't worry﹣you'll have a good time with us in this classroom．" I still remember my teacher's words．
All of us may come across some trouble in our life， and a bit of encouragement can be remembered for years．
Tip 3
When my sister and I were kids， my mum didn't have a car and our school was a 30﹣minute walk． Our neighbor offered to drive us to school when she dropped her son off， and that saved my mother a lot of time． Giving help to others can bring you happiness．
When thinking about how to become a better person， remember that small changes are also important． But "be kind to yourself" comes first． As the old saying goes， "You can't pour from an empty cup．" So in order to be a person who can give more love to this world， you have to fall in love with yourself first．

In recent years， a growing number of Chinese books and movies have been translated into other languages，（1） They have been learning Chinese and are interested in Chinese culture．Anna is one of them．Before she translated JinYong's novel Legends of the Condor Heroes（《射雕英雄传》），the writer was little known to English readers．（2）
But Anna managed to do it．Impressed（使……印象深刻）by the book's themes（主题） of good against evil，loyalty（忠诚）and love，as well as Chinese philsophy（哲学） ，Anna hoped to bring it to new readers．After five years of work， the translated book was published in 2018．（3） Many people think Anna did a good job．
Anna studied at the University of Oxford．（4） After the trip she became interested in China and began to learn Chinese．She calls herself "a clumsy（笨拙的） student， just like Guo Jing from Legends of the Condor Heroes， but one of loyal heart"．
（5） Last year， he translated the animated movie Ne Zha．He said．"I see China's stronger cultural influences．And we have a growing number of students majoring in Chinese．More Chinese stories will appear in front of new audiences．"
A．Like Anna， another translator David also learned Chinese in college． B．She took a trip to China at the age of 21． C．Many of the translators are young people． D．One reason for this was that his works were too hard to translate． E．It was reprinted（再版） seven times within several months in the UK． |
"Growing up， Einstein saw his father struggle to support the family and move the family for different jobs， Einstein had to move between schools and it was challenging for him to catch up with his new class．"
This story about the struggles（奋斗）of famous scientists can't be found in your regular science textbook， but a new study suggested maybe it should be．
In the study， 402 9th﹣ and 10th﹣grade students from four New York City high schools in low﹣income areas were divided into three groups． The students read some 800﹣word stories about Albert Einstein and Marie Curie． The control group read a regular science textbook description about their great achievements． Another group read about the scientists' personal struggles， like Einstein's running away from Nazi Germany． The third group read about the scientists' intellectual struggles， as they tried different experiments﹣﹣﹣ and failed．
As it turned out，the students who had read about scientists' struggles， whether personal or intellectual， had higher grades than students who had read about achievements． Those who weren't getting good grades to begin with gained the most． Those in the control group not only didn't see a grade increase， they had lower grades than the grading before the study began．
"We think that struggle stories showed scientists' weaknesses．" the researchers write， "which creates a sense of connection between the students and scientists． And that may make it easier for students to see them as role models．"
"When kids think Einstein is a talent who is untouchable， then they believe they will never get there， "said lead researcher Xiaodong Lin﹣Siegler， PhD．
If we want to educate a future generation of great scientists， we can start by changing the way we talk about the great scientists of the past． An 800﹣word story about scientists' failures， not just their achievements， in science textbooks will make it happen．

B． Reading stories of scientists' achievements will help educate future scientists．
C． Science textbooks should describe scientists' failures instead of their achievements．
D． Stories of scientists' struggles may make students see scientists as being untouchable．
（2）From Paragraph 4， we can know that ．
A． those good at science achieved most from this exercise
B． the control group had lower grades than the other two groups
C． the students' grades in the control group remained the same
D． the students in the third group had the highest grades
（3）What's the main idea for Paragraphs 5 and 6？
A． Findings of the study．
B． Explanations from the researchers．
C． Process of the study．
D． Suggestions from the researchers．
（4）In the study， which of the following would the third group probably read？
A． Einstein won many awards in his life， including the 1921 Nobel Prize in physics．
B．Going to college was hard for Curie because at that time women were not allowed to attend school． So， Curie had to study at secret classes．
C．By the time she reached college， Curie was able to understand five languages that top scientists spoke at that time．
D．Often working hour after hour and day after day，Curie devoted herself to solving challenging problems and learning from her mistakes．
Neijae is one of the world's youngest barbers（理发师）． At just 7 years old， she completed training at the Junior Barber Academy．
Neijae says she didn't think much about hair or styling before she heard of the academy， "I would braid（编成辫） my own hair and my doll's hair，" she said， "but I wasn't really interested in barbering course． I thought only boys could do it．"
Her mom， Graham， says she tried to get Neijae's older brother to take the barbering course．When he didn't want to go， Neijae decided to give it a try．
Neijae was the youngest student in her class． She was also the only girl． "I was never afraid，" she says．
During the six﹣week course， Neijae asked her teacher a lot of questions． "If she needed to say it in a way that she could understand， she would ask right away，" Graham says， "She's not afraid to use her voice． She's not afraid to ask questions．"
What was the most important thing Neijae learned from the course？ "Safety first，" she says．"That's always the first thing， Cleaning our tools， that's the second most important thing． I have to protect myself and my customers．"
After Neijae finished the course， a video of hers became popular． Since then， she has had the opportunity to meet professional barbers and famous persons．

If you are given only 1 yuan， could you live in a city for one day？ It seems this may be a little difficult． But students from Xi'an did it．
On April 10， more than 60 students from a middle school of Xi'an took part in the One Yuan Metropolis Survival． Students not only have to live， but also have to deal with a lot of hard tasks in this charitable（慈善的） activity． It has happened in eight cities and is going to four others ， including Beijing ， in May．
To make money． many students looked for part﹣time jobs and experience how hard life was． Zhang Qiyue， 14， asked more than 10 restaurants for a job and finally got one chance．"We were upset when they said no． But gradually， we got used to it ，" he said． After being a waiter for an hour． he got 25 yuan．
Some made use of their talents by singing and dancing in parks or shopping malls． Many people who walked by took notice and helped them． Zhao Jiacheng， 14， drew pictures and made paper crafts（手工）． "This showed it's important to learn a special skill，" he said．
Living was hard， but finishing the tasks wasn't any easier． They went to different places to finish tasks in a short time． The most amazing one was when they had to exchange things worth thousands of yuan with only a piece of paper in half an hour．"We learned how to explain to others， From a balloon to a cake to a bottle of yogurt…after almost 20 tries， we succeed，" he said． They will give all of the money they made to poor schools in Tibet．

Learning a new language is hard． In recent research， scientists found that your
chances of reaching fluency（流利） in a new language drop off at the age of 10． Does that mean you should give up your French class if you are older than 10？ No!
The research found that it's "nearly impossible" to reach fluency if you start learning a language after age 10． That's not because your language sills start to get worse． "You're still learning fast，" says Joshua． "It's just because your ability to learn starts dropping at around 10 or 11 years old．"
The researchers say people who try to learn a new language after 10 may still become quite good． But they will probably not become fluent． Kids may better than adults at learning new languages for many reasons． One is that children's brains are more adaptable（能适应的） than adults' brains． This means they are better able to change． Kids may also would like to try new things． And adults may depend on the rules of their first language． But kids are able to accept a new language without them．
（1）Why is it difficult to reach fluency if we start learning a language after age 10？
A． Our ability to learn starts dropping．
B． We can't learn fast any more．
C． Our language skills start to get worse．
（2）Why are adults worse than kids at learning a new language？
A． Adults' brains are more adaptable．
B． Adults like to try new things．
C． Adults may depend on the rules of their first language．
（3）Who would become more fluent in learning a new language？
A． Mary， 8 years old．
B． Tom， 18 years old．
C． Jenny， 42 years old．
In the past， I thought I was terrible at many things， such as math， French and science． Although I was good at drawing， I wasn't the best in my art class．I wanted to find out who I was，what I liked and how I could do it better．So， that winter，I took a notebook and kept my diary． When I filled that notebook，I started another one， and then another．
Keeping a diary helps a lot． Studies have shown that people who keep a diary sleep and feel better． It helps people remember what once happened such as dreams， friendships and happiness． Writing about bad feelings can also help brains get over themand move on． Personally， I learn better about myself and my relationships with others by keeping a diary．For example，when I am fighting with my dad， I'll try writing from his point and it works! If I want to compare myself with my classmates．I'll write something like，"I might not have clear skin， but I like my eyes．"
Right about now， you might be thinking： it sounds great， but I'm not a good writer； or I'd love to keep a diary， but my handwriting is terrible． Don't worry! Keeping a diary is not like doing your homework ﹣there are no rules， so do whatever feels best．

Mind Maps
Mind maps are a great way of showing a picture of information that you need to learn． You can use mind maps for all kinds of learning． They work very well for vocabulary when you are learning a new language．
1Draw a circle in the middle of the page and write the vocabulary subject in the middle． For example：
transport．
2Brainstorm some word groups for 'transport' and think of headings for each one． For example：
sea transport
land transport
air transport
For each one， draw a short line from the centre circle outwards． Add another circle and write the new group word in the middle．
3Look at each group and try to add more groups． For example， in 'land transport' there are two sub﹣groups；
●road
●rail
Draw two more lines， add two more circles and write the two new headings inside them．
4When you can't make any new groups， add a line for each word you know． Write the words along the lines or， if you have space， write them inside more circles．
5As you learn new vocabulary， add it to the mind map．
6To make the mind maps even better， use colour to show important ideas or parts of the map．

It's been 100 years since the actor and filmmaker Charlie Chaplin produced the film The Kid ，which many consider to be his greatest one.
Like all films at the time，The Kid was made in black and white and was silent （made without any sound，not even the characters talking）.The story is about the relationship between " the Tramp"，played by Chaplin，and his adopted （领养的）child，played by Jackie Coogan.The pair develop a partnership where the six year﹣old boy breaks windows and runs away，so that Chaplin's character can offer his services as a window fixer.
Although the film is a comedy，it also has some tragedy，reflecting Chaplin's own life.He started testing actors for the role of the Kid just a few days after his baby son had died.Chaplin was known for being hard to please，and it is said that if he could，he would have played every role in every one of his films.When Chaplin visited a theatre，a dancer brought his son，Jackie Coogan，on stage，and Chaplin knew he had his co﹣star （联袂主演者）.Chaplin later wrote， "All children in some form have talents；the trick is to bring it out in them.With Jackie it was easy.
Like the Kid in the film，Chaplin and his brother Sydney grew up very poor.They lived in London and were raised by their mother.When Chaplin was 10 years old，his mum became too ill to loo after her sons，so they had to take care of themselves.He later wrote that the film sets in The Kid were based （基于）on the places where he and Sydney had lived with their mother as children.

Can a green machine help the world's poorest kids learn better？Nicholas Negroponte thinks so.He and his team of scientists have invented a new type of computer.As a result，many children who live in poverty （贫穷） will have their own laptop computers!
Negroponte works at a university.He started a group called One Laptop Per Child （OLPC）.The people at OLPC don't work for money.They work to help children learn.OLPC makes computers that don't cost a lot.Then they sell the machines to governments of countries that have many people live in poverty.The governments then give the computes to kids for free.
The XO Laptop computers are made for school﹣aged children in developing nations.Many of these children live in faraway areas and go to schools with classrooms.In order to work，the laptops have to be lasting and student﹣friendly.
The machines have many fun characters like a built﹣in video camera，voice recording，and games.The WiFi lets students share information on the Web and read e﹣books.They also can make music and chat with friends.
Another great character is that it can last for a long time.It can be hand chargedand also can be recharged by connecting to a solar panel.Because of these characters the XO laptops make learning fun while helping the environment.
The computers have a colorful name﹣"the green machine".Negroponte thinks they could make a difference in the lives of millions of kids.He says， "Every problem you can think of﹣poverty，peace，the environment﹣is solved with education."
OLPC plans to give out over ten million computers in the next few years.Kids in Thailand，Nigeria，Brazil，and Argentina will get most of them.China and Egypt also want to take part in the program.After that，Negroponte hopes to sell computers to other countries with high poverty.

Life offers so many lessons， both practical and personal， that you're never too young to begin learning them． Here are some skills to learn as soon as possible．
Money Management 
When you start receiving money of your own． It's time to start understanding your relationship with money． In a world where you can buy any and every object， the key is to save money by buying only essentials （必需品） and a treat sometimes．
Cooking 
One great way to save money is to learn to cook for yourself． Beyond that， cooking at home also helps you control your diet for better health． If you start doing this at an early age， you will not have to depend on your parents too much．
Keeping Promises： 
Promises are a matter of honesty and should be made with care． We must learn from an early age that our word must be followed up by action． When it isn't， others will quickly lose trust in us and not respect us．
Accepting Rejection （拒绝） 
Though you must． be careful not to break your word， others' promises aren't always kept． Learn about it early， and you won't be hurt easily． Also， not every job application or desired （渴望的） friendship will work out， so remember that there are more fish in the sea．
Lifelong Learning 
No matter how old you get， there will always be things beyond your understanding． It's better to learn to be modest now rather than take a proud fall later in life． Be open to new experiences and keep learning． And it's never too late to start．
（1）How many skills are talked about in the passage？
（2）Which two skills can help you save money？
（3）If one of your friends breaks his promise to you， will you be angry？ Why or why not？

In China， writing brushes， ink sticks， paper and ink stones are called the Four Treasures of Study．Among the high﹣quality （质量） treasures， the writing brush produced in Huzhou， the ink stick produced in Huizhou， the xuan paper made in Xuancheng and the ink stone made in Duanxi are the best﹣known．
The writing brushes can be used to draw the pictures on painted potteries （陶器）．They are mainly made of the hair of animals．Those made of wool are called yanghao and those made of the weasel's （鼬）tail hair are called langhao． Their artistic effects （效果） in writing and painting cannot be copied by any other pens．
The ink stick is the pigment （颜料） used in writing and painting．The ink stick produced in Huizhou is of high quality． A story goes like this： Two famous skilled men Xi Chao and his son produced a kind of high﹣quality ink stick． As a result， the Emperor Li Yu in the Southern Tang Dynasty agreed to give them the family name"Li"， From then on， the fame of the Li Ink Stick was widespread． In the Song Dynasty， its producing area was changed into Huizhou， and it was then called the Hui Ink Stick．
Paper is among the four great inventions in ancient China． The famous xuan paper appeared in the Sui and Tang dynasties． In Xuanzhou， Anhui Province where the xuan paper is produced，it's said that Cai Lun's pupil Kong Dan took the job of producing paper but failed to make perfect white paper． Later he happened to see the ebony （檀木） in the rivers． It was wet with the water and turned white． Then he used the bark （树皮） to produce the world﹣famous xuan paper．
