Big data（数据）is a lot of sets of information that are put together so they can be used by a computer program.It can have different kinds of information from many sources（来源），such as information that comes from schools，social media sites，companies，and governments. （2） Another set can have what they like，where they go to school，and how much time they spend on the computer.
（3） The government uses it to understand how many people travel on buses or trains.The information is then used to make bus or train systems better.Companies use big data，too.It helps them understand who buys their products.For example，one company uses weather data to see when people eat the most ice﹣cream.
Big data can be used for good reasons.Some hospitals use big data to predict if a baby who is born too early will get sick.The hospital can then take extra steps to take care of that baby so he or she does not get sick. （4） It can be used to predict which kinds of people are likely to break the law or hurt others，even if they have not done anything wrong.
（5） It is because the computer programs used to look at big data and understand it are written by people.People think a certain way.Because they think a certain way，they build a model of those ideas.These ideas are then used to look at the data.Sometimes，these ideas are helpful for people or businesses.Other times，bad ideas can cause problems for certain groups of people.

One cannot discuss Chinese music without mentioning the guqin，one of the four arts-along with game of go，calligraphy（书法）and painting.It first appeared over 3，000 years ago and stands for China's solo musical instrument tradition.
At first，the guqin had only five strings（弓玄），meaning the five elements（元素）of metal，wood，water，fire and earth.Later，in Zhou Dynasty，King Wen of Zhou added a sixth string for his son.King Wu of Zhou，added a seventh string to encourage his army to fight with the Shang.
Ambiencewas important in playing the guqin.Usually，it was practiced in a quiet setting and never for public performance.Ancient artists enjoyed performing by a stream in the mountains.The sound of the guqin mixed with the echoes（回音）from the mountains，until the musician felt he was at one with nature.Playing it in snow was also an enjoyable activity for ancient artists，who believed the instrument was the purest of its kind in the world.Also，a night with moonlight was considered wonderful for playing the guqin.Wang Wei（701-761），a highly talented man of the Tang Dynasty，liked playing it in a bamboo forest on nights with moonlight most.
Guqin pieces are usually three to eight minutes long，with the longest being Guangling Verse，which is 22 minutes long.Other famous pieces include Plum Blossoms in Three Movements，Wild Geese Landing on the Sandbank and Eighteen Songs of a Nomad Flute.
Nowadays，there are fewer than one thousand well﹣trained guqin players and perhaps no more than fifty living masters.The original number of several thousand pieces has greatly reduced to only one hundred works by today.The guqin and its music was added to the list of the Intangible Cultural Heritage of Humanity（人类非物质文化遗产）in 2003.

It was Saturday again.Lily and Lucy disliked Saturdays.That was another thing the twins had in common.They shared the same clothes and tied their hair in the same manner.In fact，it was hard for their classmates and teachers to tell them apart sometimes.
Unlike their classmates，they had to get up early at seven every Saturday to prepare for their lessons.Lily had to attend the art lesson and Lucy had to attend her ballet lesson. "How I wish I could do something different today，" said the twins with one voice.All at once，an idea came to Lily and Lucy at the same time. "Do you have the same idea as me？" they asked each other and laughed.It seemed like a wonderful plan to them.After giving each other a description of their own friends，Lily put on Lucy's ballet dress while Lucy put Lily's brushes and paints into her bag.Then they left for their classes.
When the art lesson started，Lucy couldn't understand the art teacher.Unlike Lily，Lucy was poor at drawing.When the art lesson finally ended，Lucy didn't dare to hand in her work.
Meanwhile，Lily was struggling in the ballet class as well.As she had no idea about the dance steps，she had to follow her classmates blindly.As a result，she kept knocking into them.Their ballet teacher became impatient with her， "Lucy，you should remember the basic steps.You can't depend on copying what others are doing."
When Lily and Lucy arrived home，they were tired out.They decided that they would never try to be someone else that they were not.

Governments around the world are pushing for an end to plastic straws （吸管） and bags.More and more businesses are turning to paper products as a choice.Paper is considered by many to be better than plastic.However，it，too，is harmful to the environment.
Firstly，paper bags and straws are made from trees.Trees，as you know，can reduce （减少） carbon dioxide （二氧化碳） levels in the atmosphere. Theycan slow down climate （气候） change.An increase in the use of paper bags can cause more acts of cutting down trees.
Secondly，products made from paper require more energy and water.About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one.You might say that we can use recycled paper to save that energy and water.This seems to be a good idea.However，it takes even more energy and water to go through the recycling process than to make a brand new paper bag.Products made from recycled paper are also often short﹣lived.
Thirdly，paper products are heavier than plastic ones.That means they require more oil to transport.Seven trucks are needed to transport two million paper bags，while only one truck is needed to transport the same number of plastic bags.The increased weight also leads to a large amount of waste once the bags are thrown away.
Paper products are actually a lose﹣lose for both the environment and businesses.They are more expensive than plastic products.A paper straw costs about 5 to 12 cents，while a plastic one usually costs only about 2 cents.
The most environment﹣friendly solution is to avoid single﹣use products altogether.Products like glass water bottles and steel straws can be used over and over again.They are much better than either paper products or plastic products.Through increasing the use of these products，you can greatly reduce your throwaway waste and truly make our Earth a greener place!

| A． |
Plastic products. |
| B． |
Trees. |

Have you ever imagined the life in space？The following will show you the astronauts' daily life.
• Eating in space
If you go camping for more than a week with some friends，you will make sure you have plenty of foods and keep them properly.At the end of your camping trip，you would deal with your rubbish properly before the ride home.
Astronauts almost do the same thing when they go to space.Preparation changes with the food type.Some foods can be eaten in their natural forms，such as chocolate cakes and fruits.Other foods require adding water，such as cheese.Of course，an oven is provided at the space station to heat the food.But there are no fridges，so space food must be kept properly.
• Sleeping in space
After a long day at work，nothing is better than a good night's sleep!Just like on the earth，in space astronauts go to bed at a certain time，then get up and prepare for work again.When going to sleep，they have to attachthemselves，so they don't float （漂浮） around or hit their bodies against something.They usually use sleeping bags located in small crew cabins （乘员舱）.Each crew cabin is just big enough for one person.Generally，astronauts have an eight﹣hour sleep each day when they finish their task.
• Doing sports in space
Exercise is an important part of every astronaut's daily life to prevent muscle loss （肌肉萎缩）.Usually，astronauts exercise two hours every day.Lifting 200 pounds on the earth may be a lot of work.But lifting that same object in space would be much easier.That means the things for exercise need to be specially designed，so astronauts can receive the exercise needed.
Living in space is not just all work and no play.Astronauts have fun，too.They like to look out the window and play with their food.Fun plays an important role in the quality of their life.

A small cloud moves slowly through the air in a hospital operating room （手术室）.In the room a patient with cancer（癌症），lies on a table.The cloud is all around the patient，covering her body and filling her lungs（肺）.The cloud is not smoke.It is made of millions of nano﹣robots（纳米机器人）.These tiny robots move from cell （细胞） to cell in the patient's body，killing the cancer.
Fighting cancer with nano﹣robots is only an idea today，but scientists say that it could be possible in the future.Using nano﹣robots for good purposes such as fighting the illness or repairing the environment may be the way to many of today's problems.
However，nano﹣robots could be a dangerous risk as well.Because nano﹣robots are so tiny，they will have to work in large teams of many thousands to many millions.For this reason，nano﹣robots will have to be programmed（被编程）to build themselves.Scientists will not have the ability to build millions of nano﹣robots one by one.
This ability to re﹣produce is making some scientists worried.What will happen if something goes wrong in the programming？Quite a lot of crazy nano﹣robots would be far worse than any illness.Some people think that if they get out of control，nano﹣robots could make the Earth gone.
What should be done？Should we continue researching nano﹣robots or should we search for other methods？This is one of the many difficult decisions that we have to make in the future.

Last Saturday，I went to a coffee shop to meet a friend of mine.I got there ten minutes earlier.

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.
