I have tried to write a ghost story that won't make you unhappy with yourselves，with the seasons，or with me．I hope it haunts your houses pleasantly．
Charles Diclens
One Christmas Eve，old Scrooge and Bob were working busily in his office．It was a cold，foggy day．The fog was so thick that he houses opposite were like ghosts．It was only three o'clock in the afternoon，but it was already quiet dark．
"Merry Christmas，Uncle!God bless you!"cried a happy voice，It was Scrooge's nephew．"
"Bah!"said Scrooge．"Humbug!（骗人的话）"
"Christmas is a humbug!Surely you don't mean that，Uncle．"said his nephew．
"I do，"said Scrooge．"Merry Christmas!What reason have you got to be merry？you're poor．"
"OK，then，"replied the nephew cheerfully．"What reason have you got to be sad？You are rich．Don't be angry，Uncle!！"said his nephew．
"What else can I be？"answered the uncle，"I live in a world of fools!Merry Christmas!What's Christmas time to you？It's a time for paying bills without money．It's a time for finding yourself a year older，but not richer．Everyone who goes around saying‘Merry Christmas'should have his tongue cut out．Yes，he should!"
"Uncle!Please don't say that!"said the nephew．"I've always thought of Christmas time as a good time，a kind，and a charitable，happy time，And so，Uncle Christmas has never put any gold or silver in my pocket，but I think it has done me good．And it will do me good．And I say，God bless it!"
Bob，standing in the comer of the room，applauded（鼓掌）．He realized his mistake very soon，and went quickly back to his work，but Scrooge hand heard him．
"One more sound from you，Bob Cratchit，"said Scrooge，"and you'll celebrate Christmas by losing your job!"
"Don't be angry with him，Uncle．Come and have dinner with us tomorrow．"
"No．"said Scrooge．
"I'm sorry you don't want to celebrate Christmas．But I do，So a Merry Christmas，Uncle!"
"Good afternoon!"said Scrooge．
"And a Happy New Year!"said his nephew．
"Good afternoon!"said Scrooge again．
His nephew left the room，He stopped to wish Bob a Merry Christmas，And Bob replied，"A Merry Christmas to you，too．"

Say you're sitting around with some friends playing video games and someone mentions a game that happens to be one of your favorites．"Oh，that game's easy．So not worth the time，"one of your friends says．The others agree．Although you enjoy the game quite a lot，not wanting to argue with them，you go along with the crowd．
You have just experienced what is commonly referred to as peer pressure（同伴压力），also called peer
influence．You will adopt a certain type of behavior，dress，or attitude in order to be accepted as part of a group of your"peers"．As a teen，you are likely to have experienced the effect of peer pressure in a number of different areas．
We are all influenced by our peers at any age．For teens，as school and other activities take you away
from home，you may spend more time with your friends than with your family．As you become more
independent，your peers naturally play a greater role in your life．
According to Dr．Casey from Cornell University，teens are very quick and accurate in making decisions
on their own and in situations where they have time to think．However，when they make decisions in the
heat of the momentor in social situations，their decisions are often influenced by factors like peers．In a
recent study，teen volunteers played a video driving game，either alone or with friends watching．The
researchers discovered that the number of risks teens took more than doubled when their friends were
watching，compared with when they played alone．This shows that teens may find it more difficult to control risky behavior when their friends are around，or in situations where they are extremely angry．
Just as people can influence us to make unwise choices，they can also influence us to make good ones．A teen might join in a volunteer project because his or her friends are doing it，or get good grades because his or her friends think getting good grades is important．In fact，friends often encourage each other to study，or try out for sports．
While we are always influenced by those around us，the decision to act or not is up to us．So when it
comes to decision making，the choice is up to you．
52．According to the passage，Dr．Casey probably agrees that teens ．
A．like to play driving games with their friends
B．prefer situations where they have time to think
C．may take more risks when their friends are around
D．are slow in making decisions when they are on their own
53．The words" in the heat of the moment"in Paragraph 4 probably mean" "．
A．when teens avoid possible risks
B．when teens trust their judgment
C．when teens lose control over their anger
D．when teens give consideration to situations
54．What can we learn from the passage？
A．Teens are eager to be different from their peers．
B．Peer pressure has effects on both teens and adults．
C．Peer pressure does more harm than good to teens．
D．Tees think it challenging to get good grades at school．
55．Which of the following would be the best title for the passage？
A．Peer Pressure：Is It Necessary to Deal with It？
B．Peer Pressure：Is It Possible to Get Away from It？
C．Peer Pressure：Its Benefits to Teens and Friend Making
D．Peer Pressure：Its Influence on Teens and Decision Making．
All living things need energy to live and grow．This energy comes first from the sun．Plants use water and sunlight to make their own food．Animals can not make their own food，and they eat plants．Other animals then eat the plant eaters．
A food chain shows what eats what．It might show that zebras eat grass and then lions eat zabras．
Lions also eat other animals．Zebras eat other kinds of plants．So it takes more than one food chain to show how lions and zebras get their energy．
A food web shows how food chains work together．From it we can see how energy moves from plants to animals．
Plants and animals that live in hot，dry deserts depend on water as well as food．Creosote bushes have small leaves that hold water．Their seeds provide food and water for kangaroo rats．Kangaroo rats don't need to drink water．They get all the water they need from the plants they eat．Kangaroo rats keep cool by coming out only at night to look for food．Ringtail cats also come out only at night．Ringtail cats hunt and eat kangaroo rats．Coyotes eat both the kangaroo rats and the ringtail cats．
Nothing is wasted in a food web，Vultures eat dead animals．Vultures are scavengers．Scavengers do not hunt and kill other animals to get food．They eat animals that are already dead．When a ringtail cat or a coyote dies，it makes a meal for the vultures．Scavengers do an important job in keeping the environment clean．
31．Where does the energy that living things need first come from？
A．Animals
B．Plants
C．The sun
D．Plant eaters
32．Why do ringtail cats come out only at night？
A．Because they are afraid of coyotes
B．Because they are shy animals
C．Because it is very hot in the daytime
D．Because they can eat kangaroo rats
33．What kind of animal can be placed in the empty box of the picture？
A．Kangaroo

C．Cat
D．Zebra
34．Which of the following is NOT TRUE according to the passage？
A．Lions eat different kinds of animals
B．Plants are on the top of the food chain
C．Scavengers can keep the environment clean
D．Some animals get water from the plants they eat．
35．What's the best title of the passage？
A．Web of life
B．Things that we eat
C．Food in the desert
D．The place where food is from．
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 charged and 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.
（1）Negroponte thinks his laptop computers will help the world's poorest kids to .
A.work at home

The Sixth Time I Went to the Principal's Office
When I was in the seventh grade，I had problems behaving．My heart was in the right place，but I couldn't always follow the rules．I played many tricks
on my schoolmates．Once，I even pulled a girl's hair on the school bus to get her attention．As a result，I was repeatedly sent to the office of the principal（校长）．Although I hated going there，I did not hate the principal，Mr．Ratcliff．
Mr．Ratcliff was a kind，elderly man．When he spanked（ 打屁股） me for putting some ants into a
classmate's pencil box，it didn't hurt at all，but it did hurt my feelings．I thought so much of him and
moments like that seemed to prove I was hopelessly bad．
When I got called to Mr．Ratcliff's office for the sixth time，I had no idea what I had done．I
felt disappointed as I walked down there．I went into his office，sat down，and looked at the floor．Then he said the last thing I expected to hear："Kevin，I've heard you've been behaving really well lately．I
want you to know how proud I am of you，and I just called you down to my office to give you a
peppermint．"
"Really？"I was surprised．
"Yes．Now you can take that peppermint and go back to class．"
I carried the peppermint with me as if it was a gold coin．When I got into my classroom，I bragged （ 吹嘘） to my classmates about my turnaround，excitedly．I wasn't so bad after all．

It's late evening in the middle of the winter． The snow is deep， but off I go into the wild．Suddenly， I hear it： the howl （嚎叫） of wolves． Excitedly， I walk faster in the direction of the howling．
I've been working as a volunteer wolf tracker in Yellowstone National Park for over a year． It's my job to follow wolves to record information about them． Like wolves， however， I don't work alone． I'm one of a team of people who have been in a project to help reintroduce wolves to the park．
Humans have always feared wolves． From fairy tales to movies， the wolf is always the bad guy a danger to humans and other animals． In the 1920s， the organizers of the park shared this view about wolves and made the decision to drive them away from the park．As a result，the number of elk（麋鹿）in the park increased． The elk started looking for food near river banks since they didn't have to worry about wolves．This， in turn， stopped trees from growing along the rivers， doing great harm to the environment there．
The return of wolves has already made a big difference． To begin with， the elk soon learned to stay away from the rivers， so new trees have been able to grow there． The trees become home to new wildlife， such as birds， and provide food for more animals．
The park is now becoming more and more popular with those who want to see wolves in their natural environment． It has also helped the local people make more money， Tourists visit the area，stay in the local hotels， and eat in the local restaurants．
Looking at the wild animals and the beautiful sceneries around me， I am amazed at the changes the wolf has made to Yellowstone．And happily，it is playing a good guy in this story．

The cold wind blew strongly outside． Amaya was warm in her house， thinking about an article she'd read at school． The article was about kids who helped out their communities， and she thought it would be really cool to help her own town， Harvard．
The only problem was that she wasn't sure how to help． In the article， the kids had grown food for people who needed food， but it was winter． She couldn't start a garden． Amaya was deep in thought when her mom said it was time to go shopping．

Why are dogs our best friends．Maybe because they can understand our words much better than we thought，according to a study in Hungary．It found that dogs understand not only what we say，but also how we say it．
"The results were very exciting and very surprising．"Said the researcher Attila Andies，from Eotvos Lorand University in Budapest．
For the study，the researchers first trained 13 dogs for months．The dogs had to sit quietly inside machine，so that the researchers could check their activity．
Then the researcher put headphones on dogs and played people's voice to them．There were four different voice．Some were positive words，such as"well down"，or neutral（不带感情色彩的） words like"however"．The words were also in different tones（音调）．Some were positive and some were neutral．
Brain scans（扫描）showed that the dogs could recognize（辨认）words．as well as the tone of words，much like people do．The positive words with a positive tone brought the stronger activity in their brain's reward centers（反应中枢）．
"It shows that for dogs，a nice phrase can word very well as a prize，but it words best if both words and tones match．"Said Andies．
They also found that dogs deal with meaningful words with the left side of the brain and tones with the right．Human brains work in the same way．
It gave us a new understanding of language，said Andies．That is，not only do humans understand the meaning in words，other species（物种） do too．

What's a spacewalk？ Any time an astronaut gets out of a spacecraft（航天器） while in space， it is called a spacewalk． Astronauts go on spacewalks for many reasons． For example， experiments can be placed on the outside of a spacecraft． This lets scientists learn how being in space affects（ 影响） different things． By going on spacewalks， astronauts can also fix things instead of bringing them back to the earth to fix．
When astronauts go on spacewalks， they wear spacesuits to keep themselves safe． Inside spacesuits， astronauts have the oxygen（氧气） they need to breathe and the water they need to drink． To keep the astronauts and the spacecraft safe， the astronauts must leave and go back to the spacecraft through a special door． When on a spacewalk， astronauts use safety tethers to stay close to their spacecraft． Tethers are like ropes， connect the spacewalkers with the spacecraft． They keep astronauts from floating（ 漂 浮 ） away into space． Another way astronauts stay safe during spacewalks is by wearing a SAFER． SAFER is worn like a backpack． It helps an astronaut move around in space．
How do astronauts train for spacewalks？ One way is by going for a swim． Floating in space is a lot like floating in water． Astronauts practice spacewalks underwater in a huge special swimming pool． For every one hour they will spend on a spacewalk， astronauts need to train seven hours in the pool． Another way astronauts practice for a spacewalk is by using virtual reality（虚拟现实）． It looks and feels just like a spacewalk．
Today， only three countries have finished spacewalks independently． They are Russia， the United States and China． The first person to go on a spacewalk in the world was Alexei Leonov from Russia． Zhai Zhigang is the first Chinese astronaut to go on a spacewalk． The world record of spacewalks is held by Russian astronaut Anatoly Solovyev． He has been on 16 spacewalks and spent more than 82 hours outside in space．

When Reginald Johnston， a British scholar（学者）， first walked into the Forbidden City in 1919， most palaces weren't allowed to visit． But a century later， when the People's Republic of China is to celebrate its 70th founding anniversary（周年纪念） in October，the 599 year﹣ old palace complex（宫殿群） becomes the world' s busiest museum．
Open to the public
In the old days， ordinary people could only imagine what it looked like inside． When the Palace Museum was founded in 1925． the public could go into the palaces． Now 80% of the total area of the museum is open to the public and it will increase to 85% in 2025．
Embracing（拥抱） the world
"It felt like you were hit by hundreds of years of history．"Christopher Allen from Britain said， "I beginto love its history and culture．"
The Forbidden City is becoming more open and friendly to visitors． It attracted about 3.5 million visitors from abroad and 9 overseas（海外的） exhibitions were held in 2018 The Palace Museum exhibition becomes a cultural phenomenon（文化现象） everywhere it goes．
Attracting the youth
On the Palace Museums online store on Taodao， you can find more than 10， 000 cultural products． The ones with cute and humorous pictures of emperors are very popular．
Some favourite products also go offline． For example， the Kangxi Emperor's Favourite Chocolate"， the most popular drink always has people lining up（排队） to get a taste．
As a child， Xu Jing often rode a bike in front of the Meridian Gate（午门）．"I had little memory of the museum then， but now I am more willing to visit it after watching several popular TV shows about the museum， "she said．

DNA is the whole"map" of the human body.It is something that all humans have，and it tells the body what to do.DNA is the reason that we look like our parents，because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time.In 1860，Mr Mendel discovered why we look similar to other people in our family.It is because of small things called "genes（基因）"in our body.In 1953，two scientists，Watson and Crick，found out that those small parts are real messages.They are written in the DNA with a special language.
In 1961，another two scientists found the first "word" that they could understand in that language.It shows how DNA tells the cell（细胞） to build its parts.So far，scientists have found all the words in the DNA map，but we do not understand what they all do.By understanding what just one "word" means，we can help to save people from several illnesses.So the more we understand ，the more doctors will be able to do.
Most people hope that this will help to make better medicine to help sick people，Other people worry that when we learn more "words" and find out more information，we will use it in the wrong way，just to make people more attractive（有吸引力的）or stop sick people getting jobs.

We spent holidays with our uncle．He loved to go on walks to collect stones．One day，he bought us backpacks（背包） and asked us to go to the mountain with him and carry the stones．
The whole day we walked around．Every now and then he put stones in our bags．To our surprise，he also took some stones out from our bags．But we thought he had just found better stones．
When we returned to the house，we were very tired．The backpacks were so heavy that we felt relaxed when we put them down．But uncle's backpack was half empty．
"Why did you put so many stones into our backpacks？"we asked．
"I didn't．You did．"He said．"You didn't know it，but I gave you a test today．I listened to every word you said．Whenever you were complaining（抱怨），I added a stone to your bags．Whenever you talked about something with positive（积极的） thinking，I took out a stone．And now look at your backpacks．"Our backpacks were full of stones．
Your negative（消极的） thoughts are like stones．You carry themin your mind just like those stones in a backpack．The more negative thoughts，the heavier your mind．
With great love，our uncle taught us one of the most important lessons in life．

I was filled with doubts and worries until my grandfather told me to stand tall．
For me， height was my trouble． I was much taller than other girls， so I often bent（ 弯曲） my body at the back of the line． I had always felt unsafe as the tallest student of my class in Bala Cynwyd． And I wasn't looking forward to entering the ninth grade．
My grandfather didn't laugh at me． Instead， whenever I tried to bend myself in order to appear shorter， he would tell me "Stand straight and tall， Alisa． "I trusted my grandfather more than anyone else in my childhood． And whenever I was afraid of something， he always told me stories of his life．
