Canadian smart－phone maker Research In Motion(RIM), which makes the BlackBerry, says it's back. The company is 1 to reclaim a market it once dominated by 2 two new devices. The last few years have been a painful time for the company as customers deserted its platform in 3 of newer and more 4 devices. This may be the company's last chance to 5 a vital player in an increasingly crowded market place.
Two brand new devices are perhaps a fresh 6 for a company that has seen its global market share 7 from 20 percent three years ago to just over 3 percent today.
For BlackBerry CEO Thorsten Heins, it's another chance to remake a faded 8. “We have 9 been on a journey of transformation, not only a journey to transform our business and our brand, 10 one that I truly 11 transforms mobile communications into true mobile computing，” he said.
The company promises the same 12 level of network security the BlackBerry is known for, 13 a fast new browser and a more intuitive operating system. The Z10 14 much like the touch－screen phones popularized by its competitors(竞争者), but the Q10 maintains the “qwerty” keyboard that has become BlackBerry's trademark.
Besides the technical and cosmetic(外观上的) updates, Heins says the company will no longer be called RIM or Research In Motion.
“Our customers use a BlackBerry, our 15 work for BlackBerry and our shareholders are owners of BlackBerry. From today on, we are BlackBerry 16 in the world，” he said.
Shareholders will be watching if customers 17 the new devices. The company's stock has dropped as much as 90 percent in the last four years as it lost 18 to competitors. But company shares have doubled in the last four months as anticipation(预期) 19 for the new models.
Analysts say the new devices could make or 20 a company, which many people praise for starting the technological revolution in smart－phones.
Many people argue that working can be a valuable experience for the young. However, working more than about 15 hours a week is 1 for teens because it reduces their involvement with school, and 2 a materialistic and expensive lifestyle.
Schoolwork and the benefits of extracurricular activities tend to be 3 when teens work long hours. As more and more teens have filled the many part-time jobs, teachers have faced increasing 4. They must both keep the attention of 5 pupils and give homework to students who simply don't have time to do it.6, educators have noticed less involvement in the extracurricular activities that many consider a 7 influence on young people. School bands and athletic teams are 8 players, and sports events are 9 attended by working students. Those teens who try to do it all may find themselves 10.
Another 11 of too much work is that it may promote materialism and an unrealistic lifestyle. Some parents say that working helps teach teens the 12 of a dollar.13 that can be true. It's also true that some teens work to help their family or to save for college.14, surveys have shown that a lot of working, teens use their earnings to buy luxuries. These young people won't spend 15 —they can just about have it all. In many cases, they are getting used to a lifestyle they won't be able to 16 several years down the road, when they no longer have parents 17 car insurance, food, and so on. At that point, they won't have enough money to pay for necessities as well as luxuries.
Teenagers can 18 the benefits of work while avoiding its drawbacks, simply by 19 their work hours during the school year. As is often the case, a moderate (适度的) approach will be the most healthy and 20.
If you studied pictures that ancient people left on rock walls and you tried to determine their meaning, you would not detect interest in romance among the artists.1, you would see plenty of animals with people running after them. Life for ancient people's seemed to center on hunting and gathering wild foods for meals.
In modern times, when food is available in grocery stores, finding love is more 2 to people's lives. The 3 is all around us. It is easy to prepare a list of modern stories having to do with love. An endless number of books and movies 4as love stories in popular culture.
Researchers are studying whether love, a highly valued emotional state, can be 5. They ask, what is love? Toothpaste companies want us to think 6is all about clean teeth, but clean teeth go only so far. Scientists wonder how much the brain gets involved. You have probably heard that opposites attract but that 7attract, too. One thing is certain: The truth about love is not yet set in stone.
First Impression
To help determine the 8 of attraction, researchers paired 164 college classmates and had them talk for 3, 6 or 10 minutes so they could get a sense of each other's individuality. Then students were asked to 9 what kind of relationship they were likely to build with their partners. After nine weeks, they reported what happened.
As it turned out, their 10 judgments often held true. Students seemed to 11at an early stage who would best fit into their lives.
The 12 Knows
Scientists have also turned to nonhumans to increase understanding of attraction. Many animals give off pheromones — natural chemicals that can be detected by, and then can produce a response in, other animals of the same species. Pheromones can 13 that an animal is either ready to fight or is feeling 14to partnerships. In contrast, humans do not seem to be as 15 as other animals at 16 such chemicals. Smell, however, does seem to play a part in human attraction. Although we may not be aware of chemicals like pheromones consciously, we give and receive loads of information through smell in every interaction with other people.
Face Value
Being fond of someone seems to have a number of factors, including seeing something we find attractive. Researchers had people judge faces for 17. The participants had 0.013 seconds to view each face, yet somehow they generally considered the images the same as people who had more time to study the same faces. The way we 18 attractiveness seem to be somewhat 19.
When shown an attractive face and then words with good or bad associations, people responded to 20 words faster after viewing an attractive face. Seeing something attractive seems to cause happy thinking.
Nowadays it is found that school students seldom pay much attention to sports. Is it because they have no 1 in sports? It may not be the fact. They often say they have 2 more important things to do.
3 are these important things? Examinations! They have to 4 themselves for the most important School Certificates of Education Examination（毕业会考）, and also to 5 with the test and the exams in school. So many of them tend to 6 bookworms.
In the summer holidays of the former years they could do 7 they liked, but in the summer holidays of the 8 years, they have to 9 all their time to the preparation. So studies have 10 them from going in sports. Because of the pressure 11 their parents and teachers, they have to work harder and spend most of their time on books. Many parents 12 their children to pass this examination in order to get a stepping stone for higher studies or better jobs. As for the 13themselves, they want to get good results so that they can 14 their studies in the universities. So it is necessary that they 15 up their school activities, especially sports.
Indeed, a complete education cannot go 16 physical training, for a quick mind seldom 17 along with a weak body. It is well said, "All work no play 18 Jack a dull（迟钝的）boy." In one word, without a strong body, you can never 19 anything, let alone a great success in 20.
In terms of the original data in every way, the Chinese New Year — Spring Festival is the largest human event on the planet. In the seven1of the Lunar New Year, Chinese are expected to2more than $100 billion on eating and shopping — almost twice as much as Americans spend on Thanksgiving.3, Chinese predictably buy railway tickets online4a rate of more than 1,000 per second.
But it's5millions of Chinese people go home for the Spring Festival during "chunyun". All these6take place at this time.
Transport networks have set7highs for "chunyun" numbers almost every year for the past decade, the council(国务院)said.
Authorities expect travelers to make 356 million trips by8during this year's "chunyun" period. Taking the strain for the transportation is9China's high-speed railway network, now10to 20 000 kilometers — the world's longest. China's total rail network11more than 121 000 kilometers, the second largest in the world after the United States.
The "chunyun"12isn't just a wonder of logistics(组织工作)； it also shows how modern China is13.
Trains are packed with thousands of snoozing(打盹)14, reflecting education reforms that have greatly15the number of university places over the past decade.
16dressed office girls in high heels can be seen picking their way through17on their way home, which is a product of the mass migration of rural people to China's coastal cities in search of18jobs in service industries and factories.
Many of China's new middle classes will opt to drive private cars and traffic jam is now a(n)19feature of the holiday period.
Many others, however, will choose to20the confusion altogether and take a vacation abroad — increasingly an option for the new generation in China.
Teens around the world use social media a lot. But is this a 1 thing? While you can say nice and 2 things on the Internet, you could also say mean and hurtful things too. When someone says something mean or hurtful 3, it's called cyberbullying (网络欺凌).
When people say mean things to us, we feel 4, depressed and powerless. These are just some of the possible 5 effects that could affect teens who are cyberbullied. When people are often sad or depressed, they could begin to 6 suicide (自杀).They think that their lives aren't worth anything or that their lives are too 7 to handle. It's difficult to believe that one person saying mean or 8 things to another person could make him think about 9 himself, but it's true and it does happen. Now, you could 10 everything that was said. You could say that teens can just tum off their computers or their phones. They can just block (屏蔽) the person who 11 them or just simply ignore him. 12 people, especially teens love going on the Internet and talking to people. It's part of their daily lives. It's 13 to tell teens to turn them all off. In addition, 14 they block someone, the person can just 15 coming back on a different account or as someone else. Also if it's a 16 posted video, picture or message, everyone can see it and 17 report or share it. It's 18 to block everyone.
And finally no one can just 19 so many mean words that are being said to them.
Overall, cyberbullying is a (n) 20 thing that people do. There should be laws to protect people from cyberbullying.
Faster, cheaper, better--technology is one field many people rely upon to offer a vision of a brighter future. As we move into the 2020s, however, 1is in short supply. The new technologies 2_the past decade seem to mess up the things. Social media are better known for invading privacy and spreading fake news. E-commerce is3with underpaying workers and increasing inequality. Parents worry that smartphones have turned their children into screen-addicted zombies(僵尸).
4, the technologies also seem to be casting a dark shadow. AI may well threaten your job. Internet giants have changed from talent5to outcasts(被排斥者). "A mood of pessimism", the New York Times writes, has6"the idea of inevitable progress born in the scientific and industrial revolutions."
7that particular technologies might be doing more harm than good have arisen before. In the 1970s, the gloom was caused by fears of overpopulation and the prospect of nuclear disaster. The 1920s witnessed a boycott(抵制) of cars，which had been seen as a(n) 8solution to horse-drawn vehicles. Similarly, in the 19th century industrialization was greeted with9 from socialists.
However, a sense of techno-pessimism can be 10. Too often people focus on the drawbacks of a new technology, while taking its benefits for granted. Worries about screen time should be 11the much more real advantages of instant communication and easy access to information that smartphones make possible. A further danger is what Carl Benedikt Frey, an Oxford academic, calls a" technology trap. "Fears that robots will 12people of their jobs may motivate politicians to tax them. 13countries wishing to maintain level of living as their workforce ages and shrinks will need more robots, not fewer.
It's the choices people make about technology that 14the world.
As a result, the techlash (技术抵制潮) is a necessary step in the adoption of new technologies. At its best, it helps frame how society gives in to innovations and imposes rules and policies against their 15potential.
No business would welcome being compared to Big Tobacco or gambling. Yet that is what is happening to makers of video games. For years parents have1that their children are "addicted" to their PlayStations and smartphones. Today, however, ever more doctors are using the term literally.
On January 1st "gaming disorder" — in which games are played2, despite causing harm — gains recognition from the World Health Organization (WHO), as the newest edition of its diagnostic manual comes into force.
A few months ago, China, the world's biggest gaming market, announced new rules3children to just a single hour of play a day on Friday, Saturday and Sunday, and none the rest of the week.
Western politicians worry publicly about some games' similarity to gambling. Clinics are4around the world, promising to cure patients of their habit in the same way they might cure them of an addiction to alcohol or cocaine.
Are games really addictive? Psychologists are5. The case for the defense is that this is just another moral panic. In the old days, some killjoys issued6warnings about television, rock ‘n' roll, jazz, comic books, novels and even crossword puzzles.
As the newest form of mass media, gaming is merely enduring its own time in the stocks before it eventually7to be controversial.8, defenders argue, the criteria used to diagnose gaming addiction are too loose. Obsessive gaming, they suggest, is as likely to be a9(of depression, say) as a disorder in its own right.
The prosecution(指控) retorts that, unlike rock bands or novelists, games developers have both the motive and the means to engineer their products to make them irresistible. The motive10a business-model shift.
In the old days games were bought for a single-use cost. These days, many use a "freemium(免费增值)" model, in which the game is free and money is made from 11of in-game goods. That ties playtime directly to revenue.
Smartphones and modern platforms use their permanent internet connections to send gameplay data back to developers. That allows products to be12and modified to boost spending.
While psychologists argue the finer points of what exactly counts as addiction, and whether gaming's design tricks cross the line, the industry should recognize that, in the real world, it has a problem, and that problem is growing. Now that gaming addiction comes with an official WHO13, diagnoses will become more common.
Clinics are already reporting14business, as lockdowns have given gamers more time to spend with their hobby. The regulatory climate for tech is getting15. And being associated in the public mind, fairly or not, with gambling and tobacco will not do the industry any favors.
