1 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.
That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.
Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.
By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology.
According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

2 . In the Hollywood movie The Martian, actor Matt Damon plays an astronaut who grows food on Mars（火星）to survive alone on the red planet.
After seeing the movie, Washington State University physicist Michael Allen and University of Idaho food scientist Helen Joyner decided to carry out a case study helping students figure out how to farm on Mars. In the case study, students have to imagine they are mining（采矿）on Mars and decide how to feed themselves there before starting on the journey. They get a proposal from Allen and Joyner on how to select crops and take the challenges of growing crops over long periods on Mars. Students use a scoring system to select three foods to plant on Mars.
Allen found the results impressive: among 30students, “no two people have ever gotten the same answer”, he said.
Human travelers to Mars will likely have to make use of resources on the planet rather than take everything they need with them on a spaceship. This means farming their own food on another planet, one that has a very different ecosystem（生态系统）from Earth’s.
One challenge for those who would like to live on Mars is the fact that there can be no farming tools. Like real astronauts, students taking part in the study cannot take a lot of farming tools with them. As Joyner put it to his student astronauts, “You are starting with nothing.”
Besides, students also have to deal with a very limited choice of diet. “If I had to eat a single food for the rest of my life, could I do it?” Joyner asked.
But Allen believes the case study is about more than farming and eating on the Red Planet.
“I’m not teaching about growing food on Mars,” Allen said. “I’m teaching about living with choices. I’m teaching about problem solving.”

3 . During the ongoing battle against the Novel Coronavirus Pneumonia (NCP)(新型冠状肺炎), you may have read news that garlic can quickly kill the virus but it proved to be misinformation. While the nation continues to fight against the NCP, it’s also stepping up efforts to fight the spread of misinformation.
In the Internet era, the nature of how information spreads has changed largely. Information and misinformation can spread to thousands of people in seconds.
For most people, fact-checking is an afterthought — if it is a thought at all. Therefore, misinformation spreads, said The Washington Post. People simply prefer passing on information that will lead to an emotional response(反应) from readers. Whether or not it is factual is not always important.
Misinformation could be a greater danger than the virus itself. Misinformation is “making the work of our heroic workers even harder”, World Health Organization(WHO) Director-General Tedros told China Daily. He said misinformation “causes confusion and spreads fear”.
During the fight against the NCP, Ghebreyesus said that “at the WHO we’re not just fighting against the virus, we’re also battling conspiracy(阴谋) theories that undermine our response. ”
It is true that as China races to contain the NCP and minimize(减少到最低限度) its spread across countries, fears and rumors(谣言) surrounding the virus are creating their own problems on social media. “Ironically(讽刺地), speed is important on those things,” US professor Gabriel Kahn told The Los Angeles Times. “But.... those are the ones you have to be most certain about verifying (验证) before you share.”
As ordinary people, we may not be able to devote ourselves like those medical staff. But we could think twice about what we read. If you can be careful about sharing information, it’s your contribution to the fight against the outbreak.
1. According to the article, what is the main cause of the spread of misinformation?| A．The lack of fact-checking. |
| B．An increase in viruses. |
| C．People’s desire to trick others. |
| D．Changes in the way people view information. |
| A．Test. | B．Harm. | C．Guide. | D．Explain. |
| A．People have fears caused by misinformation. |
| B．It is hard to deal with misinformation across countries. |
| C．Rumors about the virus travel too fast to be controlled. |
| D．Social media creates problems for people to verify misinformation. |
| A．To share tips on how to fight against misinformation. |
| B．To introduce some misinformation about the NCP. |
| C．To call on people to watch out for misinformation. |
| D．To tell people what China has done to deal with misinformation. |
4 . Growing up, we are constantly reminded that young people are heavily affected by technology. We are the “antisocial club”, those who prefer to text our friends in the same room rather than make eye contact with them. And even though never-ending studies reveal to us the extent of our social media addiction, we should at least consider that it’s not only our young people’s problem any more.
There’s the rise of the Instagram mums, who like to post an abundance of cute baby pictures, share their mom feelings along the way and show their wonderful lifestyles. They are the so-called “Facebook mum generation”, a growing group of parents that like to overshare.
While all of this might be fine, and even a little humorous, new research suggests that parents’ technology addiction is negatively affecting their children’s behavior. According to the study, 40% of mothers and 32% of fathers have admitted having some sort of phone addiction. This has led to a significant fall in verbal interactions within families and even a decline in mothers’ encouraging their children.
There is no denying that I get annoyed when receiving the words “I’ll be with you soon” from a parent, when all I want to do is ask one question. But, at the same time, every day leaving the room to wait until my father is finished with his “serious business” (Farmville), has now become the norm. Whether you want to escape your disturbing children for a bit, or want to stay up late flicking through Twitter, know that wanting to do all of these is normal. We, your children, know how addictive it can be and how difficult it is to switch off. But before telling us to put our phones away at the table or even worse, listing statistics of how damaging social media can be for us, maybe lead by example, considering how much time you spend on the phone and how this is impacting your children and your relationship with us. Maybe in this way we can work on our addiction together.
1. From Paragraph 1, we can know that teenagers nowadays ________.| A．enjoy socializing with their friends | B．send messages to their friends every day |
| C．hate to make eye contact with their friends | D．are heavily addicted to their mobile phones |
| A．Boring. | B．Selfish. | C．Funny. | D．Meaningful. |
| A．security | B．standard | C．routine | D．custom |
| A．To share the author’s own experience with the readers. |
| B．To call on parents to get rid of their own media addiction. |
| C．To reveal that parents are always addicted to mobile phones. |
| D．To show the author’s dissatisfaction with parents’ phone use. |
5 . It's good to share, right? Growing up as kids we are told to share our toys and not be selfish. We also live in an age where discussing our feelings is encouraged. But when does it all become too much? With new fashion trending all the time, such as dance challenges and wearing a pillow as a dress, the question is: when can sharing become oversharing on social media?
What is oversharing? The term has become associated with social media, but it doesn't only belong to this platform. Imagine you head to a party and you meet someone. Within five minutes they have given away details about their personal life. While some of us may try to escape these people, according to marriage therapist Carolyn Cole, this form of oversharing could come from a strong desire to connect with someone. But how does this translate to social media?
Dr. Christopher Hand, a lecturer in internet psychology, says the more details people disclose, the less sympathy we express when things go wrong. This could be due to a belief that we attract our own negative experiences the more we share them. It seems that the idea of searching for sympathy by oversharing, is generally viewed as negative rather than the cry for help it could actually be.
However, Dr Hand's research also seems to suggest that the more positive posts we share on a platform, the more socially attractive we become. Even back in 2015, Gwendolyn Seidman PhD, said that we should avoid complaining and being negative online. We are supposed not to show off, as it's now known—especially about our love lives. It makes sense—if your date is going 'that well', would you really have time to share a photo with text?
So, how can you know if you are oversharing? Well, why not ask your friends in real life. They would probably be more than happy to tell you if your posts about your breakfast or your complaint about your lack of money really are too much.
1. Why do some people try to overshare at parties?| A．Because they want to catch others' attention. |
| B．Because they just want to show off something. |
| C．Because they have a strong desire to pour out their emotions. |
| D．Because they may expect to make a connection with someone. |
| A．explore | B．expose | C．display | D．discuss |
| A．We will become more socially attractive if we post more on a platform. |
| B．We tend to show sympathy when things go wrong. |
| C．We may be considered negative when seeking for sympathy by oversharing. |
| D．We can show off something positive especially about our love lives. |
| A．To inform. | B．To inspire. | C．To advertise. | D．To condemn. |
6 . As Shanghai prepared to introduce mandatory (强制的) garbage sorting on July I, games and toys that examined fun ways to spread information about the garbage sorting were to encourage younger people to take action.
A 15-second video of a game went on Chinese social media. In the video, players wearing VR (虚拟) headsets saw four different types of trash can in front of them, and had to throw different types of garbage into the right buckets (桶) to get points. Although it was not the only VR game in the place, visitors lined up around the booth to explore it because of the garbage-sorting theme.
“As a Shanghai, I am in great need of this game. Maybe I won't need to check how to categorize (分类) each piece of garbage on my phone while going through all my garbage every day if I play this game more often,” said Zhou Zhou, a young Shanghai. But some social media users in Shanghai have complained (抱怨) about the difficulty of sorting different types of garbage.
Wu Xia, founder and CEO of VitrellaCore, the company that created the game, said the idea was to provide an interesting way of learning about garbage sorting. “It’s simple and easy to understand. People can practice sorting garbage without actually going through their trash, and it is a more fruitful method than using paper materials when training volunteers,” Wu said.
1. What is the purpose of the VR game?| A．Just for fun. | B．Teach students to sort garbage. |
| C．Help to release (释放) stress . | D．Teach children to protect environment. |
| A．It is too hard to sort garbage. |
| B．There are too many people lining up. |
| C．The VR game should be more interesting. |
| D．There are more ways to use paper materials. |
| A．Effective. | B．Interesting. | C．Traditional. | D．Scientific. |
| A．Young people like VR games more. |
| B．Shanghai performs mandatory garbage sorting. |
| C．Games were used to help young people sort garbage. |
| D．Learning by playing VR games is practical for the young. |
7 . Winslow Homer was a famous American painter. Since Art History class in college, I had always admired his works and I was lucky to see a large exhibition of his works when I was in my early 30s. It was at this event that I bought a print of his painting “Snap the Whip”. It always hung in my classroom until I retired from teaching.
I thought it truly captured the freedom and fun of childhood. In the painting, a group of young boys are playing a game arm in arm on the grass ground in front of a farm house. They are jumping and laughing wildly with great joy. One of the boys is falling down to the ground. They are not even wearing shoes!
During my last year of teaching，there was a young woman in her first year of teaching right next door to me and we got to be good friends. She had been an art student before taking up education. Her eyes were drawn immediately to this print when she entered my room. So on my last day of teaching, after the students had left, I took the painting off the wall and walked next door and gave it to her.
She was really surprised，but very glad to have it. I was delighted that she liked it and all the students she would have would treasure it as much as I had. We found the perfect place for it on one of her walls and hung it together. I was happy that she brought back this wonderful memory for me.

8 . To me, life without music would not be exciting. I realize that this is not true for everybody. Many people get along quite well without going to the concert, and listening to the record. But music plays an important part in everyone's life, whether he realizes it or not. Try to imagine, for example, what films or TV plays would be like without music. Would the feelings, the moving plot, and the greatest interests, be so exciting or dramatic? I'm not sure about it.
Now, we have been speaking of music in its more common meaning----the kind of music we hear in the concert hall. But if we look at some parts of music more closely, we discover them in our everyday life too----in the rhythm of the sea, the melody of a bird in the woods and so on. So music surely has meaning for everyone, in some way or other. And, of course, it has special meaning for those who have spent all their lives working on playing or writing music.
It is well said, “Through music a child enters into a world of beauty, expresses himself from his heart, feels the joy of doing things alone, learns to take care of others, develops his mind and makes his body strong.”
1. What does the writer say more about in the text?| A．Life full of music. | B．The importance of music. |

| A．go to the concert instead of enjoying music |
| B．get along quite well without music |

| C．looking | D．singing |
| A．is very necessary for our everyday life |
| B．is very important, especially for children |
