Put technology in the hands of someone like Elon Musk and it can send people into space, make a future of clean and renewable energy a reality, or build electric cars. Put in your hands, and it can help you achieve all sorts of things, from learning to code to learning a language.
Educational apps are becoming increasingly popular as a supplement(补充), and sometimes as an alternative
(替代物), to traditional education. Why? Well, for starters, it’s extremely convenient to learn on a pocket-sized device that you already carry around with you at all times. The best apps are also highly interactive and adaptive, coaxing you in and getting you hooked on learning.
But apps, just like textbooks and language lessons, are a medium through which a language can be studied. The way you use them will affect how successful you are. If you flick through a textbook and don’t dare say a word in your language lessons, you’ll make slow progress. The keen reader who repeats each exercise in the textbook and engages the teacher in the conversation will move ahead. So how do you ensure you get the most out of your app, and what should you consider before you install(安装) one?
Before that, a very quick introduction: I developed the following five points from my experience as both a language teacher and learner, and from working in startups in the field of language. I spent six years teaching in Germany and Spain as well as developing a video learning startup. However, I first came to language learning late. I started learning Spanish at 22, and was able to use Spanish and German freely by about 28. I’ve been using language apps for the last few years, and participated in two successful one-week challenges to go from zero to hero in Italian and French. If you’re interested, you can see the French challenge here.
So, just before downloading an app, here’s what you should think about…
1.We infer that Elon Musk is most probably __________.
A. an app developer
B. a language teacher
C. a professor at college
D. an engineer and tech company owner
2.What does the underlined part in Paragraph 2 probably mean?
A. Causing you to get tired of learning.
B. Encouraging you to interact with others.
C. Making you keep learning the language.
D. Providing new leaning methods for you.
3.What does the author want to show by giving the example of how one uses a textbook?
A. Doing exercise is important.
B. Different people learn differently.
C. Textbooks have become out of date.
D. We should use a language learning app correctly.

Entrepreneur and CEO of Tesla and Space X, Elon Musk may have a little more time on his hands, as he’s leaving his position on the board of the Open AI, according to a blog post.
The departure is likely the result of Tesla’s moving into the field of Artificial Intelligence(AI)，which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Elon.”
Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv. Org, detailing the possible secure threats that come with “malicious” AI. In fact, Musk has heard of the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people. ”
Musk’s departure from the Open AI board could mean big things for Tesla. As Elon Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own Al projects than we thought.” He added, “Those who have had their ears to any rumors that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open Al development as a sign that the company is inching closer to that unapproachable goal. ”No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.
1.Why does Elon Musk leave his position?
A. To create safer AI.
B. To build the powerful Internet.
C. To develop social communication.
D. To avoid a possible conflict with Tesla.
2.What is the Elon Musk’s attitude towards the AI?
A. Suspicious B. Negative.
C. Sympathetic. D. Supportive.
3.What can we infer from Elon Goodbye’s comments?
A. Level 5 autonomy is impossible.
B. The rumors about Tesla is meaningless.
C. He has no confidence in Open AI.
D. Level 5 autonomy could set human drivers free.
4.What’s the best title for the text?
A. Elon Musk is planning to compete with AI.
B. Elon Musk is stepping down from AI safety group he co-founded.
C. Elon Musk: AI is humanity’s biggest existential threat.
D. Elon Musk: Open AI will take new measures to cooperate with Tesla.

Elon Musk, perhaps the world’s most famous businessman, has a habit of making statements that stretch the bounds of believability.
On July 16th, 2019, he introduced a new type of brain-machine interface (BMI), starting from the design of a “neural lace (神经织网)”, a net of thin electrodes (电极) that capture the information from the brain. However, the electrodes must be flexible, so that they do not damage brain tissue and will last for a long time. And to make the implantation (植入) of so many electrodes safe, painless and effective, the process has to be automated.
Mr. Musk’s team does indeed seem to have made progress towards these goals. Its presentation included videos of a robot that is best described as a sewing machine. This robot grabs “threads”, and shoots them deep into the brain through a hole. The firm has also designed a chip that can handle signals from as many as 3,072 electrodes.
With all these technological breakthroughs, the firm now hopes to help people overcome such illnesses as blindness and paralysis. They designed a small device that would sit behind someone’s ear, picking up signals from the implanted chip and passing them on as appropriate. In a few years, using a brain implant to control your devices may be as prevalent as wearing wireless earphones today. Finally, Musk predicts neural lace will allow humans to be combined with AI systems, thus enabling the species to survive.
Though, as this announcement shows, Mr. Musk does have a habit of presenting himself as the hero of the human race, the idea that some machines at least will come under the direct control of human brains seems possible to be carried out. The biggest barrier to this happening will probably not be writing the software needed to interpret brainwaves, but rather persuading people that the necessary surgery, whether by sewing machine or otherwise, is actually a good idea.
1.We can learn from the first two paragraphs that _____.
A.electrodes should be flexible to extend life
B.Elon Musk constantly comes up with unexpected ideas
C.a neural lace is used to store information from the brain
D.electrodes are implanted by top surgeons for safety reasons
2.What does the underlined word “prevalent” in Paragraph 4 probably mean?
A.Useful. B.Common. C.Professional. D.Appropriate.
3.What is the hardest part of carrying out BMI?
A.Convincing people to accept the surgery.
B.Developing devices to perform the surgery.
C.Writing the software to interpret brainwaves.
D.Informing people of the success of the surgery.
4.What is the best title of this passage?
A.The Neural Lace, A New Type of BMI.
B.Elon Musk, the Hero of Human Beings.
C.Artificial Intelligence, the Way to Survive.
D.A Brain Implant, A Step to Control Machines.

In 2012, an iPhone fell into my hands. This smart technology seemed like the entrance to only fun and positive things like chatting with friends and blogging.
However, seven years later, I had become horribly limited to it. Recent reports show that I’m not alone. According to a study, the average American spends five hours a day on smart devices (装置) and about 2.5 of those hours are spent on social, messaging, media and entertainment apps.
It’s hard to explain when the love and joy I felt for my iPhone turned into a dependency. I fell asleep to my phone every night and woke to it each morning. I checked the weather app every morning before I chose how to dress for the day. I used it to help me find my way through a city I should know well enough on my own. I updated my email box every time I picked my phone up.
Just like with any addiction, my phone dependency began to influence my life. While spending time with family, I’d stare into a small screen on my lap instead of being involved in communicating with my loved ones. At work, my productivity levels dropped. And then, my four-year relationship came to an end. Eventually, I was left with years of memories and a mobile phone that couldn’t provide enjoyable company across a dinner table, share in the joys of experiencing a concert or kiss me goodnight before bed.
Now, I move through life with more purpose and intention. I’ve cut back on carelessly giving away my limited time and attention to my phone. Instead, I focus my efforts on being as present as possible. Truly training the mind to stay present is a long and challenging road, but it’s important to start somewhere.
I hope you’ll take a deep look at your own phone habits and reevaluate how important a role you are letting it play in your life. Whether or not you’ve reached a place in your life where your screen time feels problematic, there’s no harm in mindfully giving your current practices some thought.
1.What does the author mean by saying “I’m not alone” underlined in Paragraph 2?
A.He takes his iPhone for company.
B.He has many friends around him.
C.There’re many Americans like him.
D.Blogging brings him great pleasure.
2.According to Paragraph 3, the author _________.
A.was quite confused about some apps
B.became hopelessly addicted to his iPhone
C.was afraid of spending more time on his iPhone
D.never dressed himself by checking the weather app
3.What does Paragraph 4 mainly focus on?
A.Why the author’s productivity levels dropped.
B.Why the author finally had phone dependency.
C.How the author bravely corrected his mistakes.
D.How the author’s life was negatively affected.
4.What does the author intend to do in the last paragraph?
A.Persuade people to live a no-phone life.
B.Advise people to use their phones reasonably.
C.Inspire people to consider their roles in life again.
D.Urge people to devote their spare time to screens.

It’s always exciting to think about the future and what kind of technology might exist in years to come. But what if that future is closer than you think?
The name Magic Leap is starting to spread across the Internet, and for a good reason. The Magic Leap technology company in the US has been working on something new and exciting, keeping it so secret that even the people working on the project have been hidden from the media. But recently they have started to release more information, and it seems that the future of computing is about to change dramatically.
Magic Leap’s preview shows the possibility of a classroom where you can interact with a miniature 3-D man and watch animals floating in front of your eyes. You could come face to face with fierce creatures like tigers and sharks, and more might be possible very soon.
The company hopes to create new technology that mixes reality and virtual reality computing. This means that the way we interact with computers could change completely, and so could the gaming industry.
Imagine a game in which you can not only look after a dragon on a screen, but also see it walking around your home, feed it and play with it. This is a world where movies will make you jump as things come, flying at you. Rio Caraeff, the company’s chief content officer, said that instead of staring at a phone screen, “the world becomes your screen”.
All of this could be the next step for Magic Leap, and their newly-released video suggests so. The video shows a small elephant floating in the hands of its user, a virtual reality pet that the user can interact with. Exciting to think about, no?
It seems that the excitement has inspired other companies who are lining up to join in on this new project. The technology, called Cinematic Reality, is attracting the attention of large companies like Google, who are already investing large sums of money in the project hoping to see it become a reality.
1.Which of the following is TRUE about the Magic Leap technology company?
A. The company is working on new technology that could improve the future of computing.
B. The company keeps updating the media on its progress.
C. The company has just discovered a way to mix reality and virtual reality computing.
D. The company’s newly released video is about the interaction between a dragon pet and its user.
2.What could a classroom in the future look like, according to Magic Leap?
A. A miniature 3D man could take the place of teachers.
B. Students could be encouraged to raise a virtual reality pet on campus.
C. The gaming industry could be invited to help students improve their studies.
D. Students could interact with virtual reality animals.
3.How could Magic Leap’s technology change the world according to the article?
A. It could discourage people from playing a lot of computer games.
B. It could turn the whole world into an interactive screen for its users.
C. It could help people improve their ability to interact with others.
D. It could make it hard for people to distinguish between virtual reality and reality.
4.What is Google’s attitude toward the technology named “Cinematic Reality”?
A. Unconcerned. B. Optimistic.
C. Worried. D. Negative.

Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resetting your body clock. 1. Here’s how to make one.
● 2. In order to make a change, you need to decide why It’s important. Do you want to get up in time to have breakfast with your family, get in some exercise，or just be better prepared for your day! Once you are clear about your reasons, tell your family or roommates about the change you want to make.
● Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes，and bags. 3. That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.
● Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 4.
● Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record.5. If not, take another look at other methods you could try.

Imagine that someone in your neighborhood broke the law, and the judge put the whole neighborhood under suspicion. How fair will that be? Well, it happens every day to high schoolers. Just because some students have stolen things in shops, all of us are treated like “shoplifters”. Even though I’d never steal, store employees looked at me like I’m some kind of hardened criminal mastermind.
For example, during one lunch period, my friend Denny and I went to the Grab “n” Go on Tuesday. We arrived to find a line of students waiting outside. A new sign in the window told the story:“ NO MORE THAN TWO STUDENTS AT A TIME.” After 15 minutes, we finally got in. But the store manger laid the evil eye on us. I asked him about the new sign, and he said, “You kids are lifting too much stuff.” You kids? Too much stuff? Not only were we considered to be shoplifters, but brilliant, greedy shoplifters.
The Grab “n” Go isn’t an isolated case. Earlier this year, a department store worker told me to leave my backpack at the front of the store. When I asked who was going to keep an eye on my stuff, she said, “Don’t worry. It isn’t going anywhere.” In other words, I had to risk losing my stuff so that the store wouldn’t have to risk losing theirs. “Don’t worry,” I replied, “I don’t need to shop here.”
The most annoying thing, though, is the way employees watch my friends and me. It’s almost strange and frightening. Once, at a drug store, I went down an aisle and found a guy standing on a box, stocking the shelves. He was watching my hands, which were empty. He got down off his box and rushed off, as if he was going to get the store manger. How crazy is that?
You know, this kind of prejudice can go both ways. I work at the CD Crib, and every day I see adults commit a terrible crime. They put on a set of headphones and sort of dance to the music. Talk about bad! Tomorrow, I’m going to put a sign in the window: “ NO MORE THAN TWO ADULTS LISTNENING TO MUSIC AT A TIME.”
1.“ Shoplifters” ( Paragraph 1) refers to _____________.
A. the neighbor B. thieves
C. employees D. store owners
2.The manager of the Grab “n” Go thought that _______________________.
A. people might be angry about the lining up
B. the shop might be over-crowded
C. students might steal things
D. kids should be accompanied by their parents
3.What is the tone of the writer?
A. Angry B. Sad
C. Pleased D. Excited
4.By saying “this kind of prejudice can go both ways”, the writer intends to _______________.
A. put up a notice to prevent adults from committing a crime.
B. encourage adults to listen to CDs before they buy them.
C. stop adults from talking bad things when in CD stores.
D. accuse adults in the same way as they did towards the boys
5. How does the writer develop his argument?
A. By example B. By classification
C. By comparison and contrast D. By cause and effect
