In the modern world, computers and the Internet are getting more and more popular. Most people think they are very useful in their studies and lives.
The first computer was made in 1946. It was very big and it worked slowly. Today computers are getting smaller and smaller but working faster and faster. At the same time, our world is getting smaller and smaller because of the Internet. The Internet came into the world about twenty-five years later than computers, but it is important, too.
Many students like the Internet so much that they would not like to do anything else. They make friends on the Internet, but maybe they have never seen these friends. Some of the students are cheated by the “online friends”. Because of the Internet, some students can’t work hard at their lessons. Many of them can’t catch up with others on the school subjects. A few of them have to leave school.
We can use computers and the Internet to learn more about the world. But please remember, “Not all good things are good for you.”

If aliens are discovered one day, scientists fear their language may make it possible to understand them. But John Elliott of needs Metropolitan University in Britain has come up with a program that can figure out the structure(结构)of their language. He thinks that’s the first step in understanding what they are saying.
Dr.Elliott’s program would compare an alien language to a database(数据库)of 60 different languages in the world to look for a similar structure. He believes that even an alien language will have its own structure.Language has to be structured in a certain way, or it will be harder to use,he told New Scientist magazine.
Research had shown that it is possible to know if a signal(信号)carries a language rather than a picture or music. Dr.Elliott has gone a step further by finding a way to pick out what might be words and sentences. Because languages have different word orders, Dr.Elliott has set up a library of the sentence structures of 60 human languages.
If a message is received from outer space, it could be compared against this database. Scientist would then be able to see if ti’s similar to any human language, or a mix of the language.
However, Dr.Elliott also said that in order to translate what the aliens are actually saying, it may still be necessary to have a code book.

【推荐3】Photography has been a popular hobby for a long time. People used to take photos with cameras and then have them printed to share with friends. It’s still popular these days, but thanks to technology, this old hobby is changing a lot. For example, and 30 seconds later your photo is online. People everywhere are seeing exactly what you just saw.
This is called photo sharing. Photo sharing is using the Internet to share and store digital photos. There are many kinds of photo sharing, but we are going to look at two：social network sharing and subscription (订阅费)based sharing.
A social network is a website that people use to have fun and keep in touch. If a website lets you chat with friends, share information and send pictures, it’s a social network. The world’s biggest social networks are Twitter, and of course, Facebook. If you have ever posted a photo on a social network site, a problem brought by it is that it’s easy for strangers to see your pictures.
When you use a subscription based photo sharing website, you pay money to store your photos online. Then, you can use your photo anytime. This is safer(隐私).The problem, of course.
Technology has also brought us a new business called print on demand. To use print on demand, you have to go to a photo book company. Here’s how it works. You select some photos and you send them to a photo book company. The photo book company arranges your photos into a fancy book. You can pick every detail of your photo book. You can choose the size, shape and brightness of every picture. People pay photo book companies to make photo albums, calendars, postcards.
Technology is changing our lives all the time. What will be changed next? Who knows?

Have you ever shouted at your computer because it wasn’t working? Of course, your computer can’t “shout” back. But AI researchers have been working on computers that can argue and perhaps even win debates (辩论) with humans.
IBM scientists recently published a paper in Nature about their new AI system—Project Debater. It can debate with people in front of a live audience. After listening to arguments from its opponent (对手), the system can search around 400 million online articles in less than five minutes. And then it looks for ideas that can support its own argument.
Testing on the system began in 2019. When it debated with Harish Natarajan, a professional debater who holds the world record for the most debate competition victories. The topic was about subsidizing preschool (资助幼儿园)—and Project Debater argued to support this idea. Although Project Debater lost the debate in the end, the audience said it performed very well. Interestingly, 58 percent of the audience said that Project Debater increased their knowledge about the topic—only 20 percent said the same about Natarajan.
According to Scientific American, results show that the system is able to form logical statements (有逻辑的陈述). However, ★ . Their goal is to help humans make better decisions, according to Ranit Aharanoy, manager of the Project Debater team. “It can debate both sides, so it can very quickly help you understand both sides of the problem, so you can have a wider view of the problem and make a more thoughtful decision.” Aharanoy said.
Let’s wait and see how the Project Debater will develop in the near future.

【推荐2】Imagine using your coat to look through the internet, send and receive messages, and even read a map. Yes, you read that correctly—your coat.
It may sound silly, but it’s something scientists are working on. Researchers at Shanghai’s Fudan University have made a new type of cloth that can be used as a digital display （显示屏）.
Professor Peng Huisheng and his team have spent 10 years trying to make “digital cloth”. After testing different combinations, they chose two materials that worked: a silver-plated yarn （镀银纱）that can light up and a kind of thread （纺线）that conducts （传导）electricity.
The results have been admirable. It’s not only wearable and foldable, but also washable. After being put through 100 wash-and-dry cycles in a washing machine and folded 10, 000 times, the cloth remained almost unchanged.
Peng believes that the new cloth could be used for many things. For example, it could allow a driver to view a GPS map on their arm while they drive around. It could also help people communicate better if they have language barriers （障碍）or disabilities.
In one test, Peng’s team collected brainwaves from volunteers who had either been playing a game or meditating. The waves were then translated into messages like “anxious” or “relaxed” and shown on the cloth. This could help deaf-mute （聋哑的） people “talk” to each other in the future.
“We hope that new materials will shape next-generation electronic devices by changing the way we interact with them, ”said Peng.

【推荐3】The future of the city is here. An American company, Sidewalk Labs, won a competition to design a new neighborhood in Canada. The competition is to make the buildings, public spaces and transportation (交通) in the area of Toronto better.
The neighborhood’s name will be “Quayside”. It will have many good and new technologies (技术). Some examples are self-driving buses and shared-ride taxi robots (机器人). There will also be fewer cars and more room for parks.
The buildings will use plastic (塑料) instead of wood or steel, so they are cheaper and easier to change. People will have user accounts (账号) to get into the fitness center, or get help fixing something. They will even be able to use them to ask the neighbors to be quieter.
There are also many worries about the project. One is that there is already a housing problem in Toronto, and Quayside may not help with that. So it is important for Quayside to be made for all kinds of people, rich and poor, old and young.
Another is about data (数据) collection. People are worried about their privacy (隐私). However, Dan Doctoroff, the CEO of Sidewalk Labs says that the data will only be used to improve things in Quayside
As this kind of neighborhood is new and different, there will be many things to do. But it will be interesting to see how this future neighborhood works.

【推荐1】Do you think England teaches maths the same way as China does? The answer is yes!
In England, our maths lessons are similar to what kids have in China. During each lesson, our teacher teaches us a new maths concept (概念). Later, we finish either a worksheet or a booklet to improve our understanding. We have a test once every term to see how much we have learned.
But things were a little different in Year 7. We didn’t do any end-of-year exams. We did something different—a maths test to form “sets”. What does set mean? In each class of 26 students, only 30 percent will reach the top set. The other students will be in the medium set. To get into the top set, you need to get high scores on your maths exams. With the sets, teachers can focus on a smaller group of students who are good at maths. They can give them harder questions to do.
My maths sets exam had two parts, A and B. For Part A, we had 40 minutes. It was mainly arithmetic (算术) and questions about numbers. For Part B, we had 50 minutes to answer problem-solving questions.
I got into the top set. It is true that the lessons are much harder. But I like it because it makes me more competitive.
1. In England, students take a test once every term to ________.| A．learn a new maths concept |
| B．check how much they’ve learned |

【推荐2】Every year, as the summer days grow shorter, an amazing change happens in Canadian forests. As summer changes to autumn, the trees turn colors, changing from summer greens to shades of red, orange, and yellow. It’s a truly wonderful sight! From a distance, the forest looks as if it’s on fire.
When I was a boy, my grandmother told me that a strange little man came at night with a paint brush to paint the leaves those wonderful colors. And I believed her for it was a wonderful way of explaining this change to a little boy. But as I grew older, my natural curiosity led me to do some research on my own. As always, science had the answer.
Trees need food, just like all lives. Leaves produce food for the tree. It’s just sugar, which is sometimes called glucose (葡萄糖). Leaves use sunlight to change water and CO2 into oxygen (氧气).The process by which leaves do this is known as photo-synthesis (光合作用). A chemical called chlorophyll (叶绿素) helps make this happen. Chlorophyll is the reason why leaves are green summer.
However, Canadian winters are long, cold and dark. There isn’t enough sunshine in winter for the leaves to make food. In autumn, as the days shorten, the trees get a signal to slow down. It’s time to take a rest. Don’t worry, though. They have enough food prepared to last all winter.
When the leaves stop making food, they no longer need to make chlorophyll. Slowly, the chlorophyll disappears. Remember, this is the chemical that makes leaves green. As the chlorophyll goes away, so does the green color. We begin to see the other colors that are always there. We could not see them before because green is a strong color.
1. The writer thought ________ changed the color of leaves in autumn when he was a child.| A．the wind | B．a strange man | C．the sun | D．his grandmother |
| A．Because the chlorophyll goes away in the leaves. |
| B．Because green color has a chemical change with sunlight. |
| C．Because the trees need more food in winter. |
| D．Because cold and dark environment can make new colors. |
(① = Paragraph 1)
A． | B． | C． | D． |
| A．We could not see the other colours before because they are not always there. |
| B．The writer always believes his grandmother’s explanation. |
| C．When the leaves no longer need to make chlorophyll, the trees can change from summer greens to shades of red, orange, and yellow. |
| D．When the writer was a little boy, he did some research on his own to know the answer. |
【推荐3】Nanako Hama was holding a light envelop. When she tore it open with care, locks of hair emerged. Many strangers send Hama locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change. But hair possesses useful qualities that it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks in the ocean.
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mat, which are then used to clean up the floating oil. “Hair is particularly well-suited for this,”says MoT co-founder Lisa Gautier.“That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair—significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil. Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氮), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes—for oil and soil,” Hama says.
1. How does the author introduce the topic?| A．By presenting a scene. |
| B．By detailing the background. |
| C．By describing the usage of hair. |

【推荐2】In some places in North Africa, great cities once stood. There were gardens and trees and grass. But now these places are like deserts(沙漠). Scientists have begun to study this land to find out what happened. Many of them think the land died when the trees were cut down. Trees help other plants grow. Tree roots hold the earth in place. They stop the soil from being blown away. In forests, leaves on the ground keep rainwater from running off. Trees near farms protect growing plants from strong winds.
Once there were hundreds of farms in the Southwestern United States. Then the farms turned into fields of dry land, because few trees grow in the dry Southwest.
Now we try to save trees. In many forests, when a tree is cut down, a new tree is planted in its place. We do not want the land to die.

【推荐3】On January 27, in order to win the new pneumonia Resistance War（抗击新型肺炎战）, the Ministry of Education issued（教育部公布） a notice on putting off the start time of school in spring 2020. It was said that school should not start before March. The exact start time of school will depend on situations and further notices.
However, many parents are very worried that putting off the start of school may affect（影响） children’s studies. If they have such a long winter vacation, children will not learn any knowledge, read books or study at all. They may forget what they have learned before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical and mental health.
In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform（平台）, where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.
It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection（感染) of the disease, but also make them study at home, improve their learning ability, and truly achieve “no suspension of classes”. Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.
Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical health at home.
