【推荐2】Do you play video games? If so, you aren't alone. Video games are becoming more common and are increasingly enjoyed by adults. The average(平均)age of gamers has been increasing, and was said to be 35 in 2016. Changing technology also makes it possible for more people to play video games. A new type of casual gamer has appeared, who plays on smart phones and tablets in spare time throughout the day. So, we know that video games are an increasingly common form of entertainment, but do they have any effect(影响)on our brains?
Over the years, the media have been talking about the effect of video games on our health and happiness. "Games have sometimes been praised or criticized. Also, playing video games is a popular activity, so everyone seems to have strong opinions on the topic," says Marc Palaus, who carried out research together with his colleagues. They collected the results from 116 scientific studies, 22 of which looked at structural(结构的) changes in the brain and the rest of which looked at changes in brain functionality(功能).
The research shows that playing video games can alter how our brains perform, and even their structure. For example, playing video games affects our attention, and some studies find that gamers show improvements in several types of attention, such as sustained attention or selective attention.
Video games can also be addictive(使人沉溺), and this kind of addiction is called "Internet gaming disorder". Researchers have found functional and structural changes in the neural system(神经系统)in some people. These neural changes are basically the same as those seen in other addictive disorders.
So, what do all these brain changes mean? "We pay attention to how the brain reacts to video games, but these effects do not always turn to real-life changes." says Palaus."As video games are still quite new, the research is still in its early stage."
1. Why does a new type of casual gamer appear according to Paragraph 1?A.Because the work pressure becomes bigger. |
B.Because video games become more popular. |
C.Because people have fewer activities to relax themselves. |
D.Because changing technology makes it convenient to play video games. |
A.Change. | B.Avoid. | C.Doubt. | D.Cancel. |
A.Why video games affect brains. | B.When video games affect brains. |
C.What effects video games have on brains. | D.How video games affect our health. |
A.They can certainly change people's real life. | B.Their effects need to be further studied. |
C.They can help people feel more relaxed. | D.They are really harmful to people. |
【推荐3】Here is one of the world's largest indoor ski-slopes(滑雪斜坡). It covers an area of 22, 500 m2, about the same size as three football fields, and the temperature is about-1℃ to-2℃. However, the strangest thing about this place is that it's in the middle of the desert! It's called Ski Dubai.
It sounds crazy, but it just shows how serious people are about having fun. We spend huge sums on sports facilities(设备). We pay our sports stars lots of money. And we spend hour after hour playing games! I wonder if all the sports-lovers and game-players in the world aren't a little crazy. I know I am. I was once driving past a football field where some kids were playing. I turned to watch and crashed my car. I know it's stupid but I can do nothing about it. As someone said, "Football isn't a matter of life and death. It's much more important than that! ”
Of course, it isn't that important really. No game is. But the problem is that games are addictive(使人上瘾的). From the tennis court to the golf course, you'll fred participants and spectators who can't live without the drug of their choice. It could be a good thing. After all, it's really true that sports and games help us to relax. Maybe if it wasn't for sport, our societies would be more violent. Perhaps sport is a substitute(替代)for war? It's hard to think of a quieter, more peaceful game than chess, and what's the purpose? Getting control of your opponent(对手)'s king. And surely, it's better to have wars in athletics stadiums rather than on battlefields.
What's more, playing is natural. Little cats chase balls of wool and little dogs pretend to fight. Games help us perfect our skills and prepare us for the serious contest of survival.
But do all games help us relax and stay away from violence? What about computer games? A recent article in New Scientist suggests that playing violent video games makes people more likely to commit violent crimes.
Are these games a rehearsal(彩排)for life or a substitute for life? Do we play instead of facing up to our real problems? I don't know. But what I do know is that I need a break. Something to help me relax. Skiing would be nice. I wonder how much it costs to get to Dubai.

【推荐3】Many of us may have experienced the pleasant moment of seeing recommended (推荐) songs after we listen to some songs on a music app. When we open shopping websites, we often see things we want to buy on the home page. The businessman can decide which is the best place to build a new entrance in a big supermarket in the city center. If you want to take a taxi on a taxi app, it can even guess where you want to go before you tell it! Aren’t these things amazing?
This is based on data (数据). Data is no longer only about numbers, but information from almost every side of our lives: our shopping habits, interests or what we eat. All of this is called “big data”. In December 2017, President Xi Jinping called for China to speed up its big data strategy (战略) to better serve social development. As a result, people’s lives can be improved as well. He also asked for greater use of big data in areas like education, and transportation.
We have seen big data being used more often in China in the past few years. The role it plays in travel is just one example. Many travelers today like to share their experiences with others on the Internet. All the data that travelers share online is helping the tourism industry get a lot of information. After the data is analyzed (分析), these tour sights can know about travelers’ needs better. In this way, services will be improved, which is helpful to the development of the whole industry. As a result, travelers can expect better tours in the future.
Moreover, big data is also an important growth tool for trade. With growth rate of 30 percent every year, sales of big data industry in China will reach one trillion (万亿) yuan yearly by 2020. Having so many good influences, big data is sure to be seen more and more in China.

【推荐1】What do you say after you burp (打隔)? In the US, people usually say “excuse me” after they burp. I do it all the time.
But why do people say it in the first place? In Western culture, people think burping is a bit rude (粗鲁的). Burping loudly in public is especially rude. So when we burp, we say “excuse me”.
However, when we sneeze, we don’t say “excuse me”. In fact, it is polite for other people to say “bless you (保佑你)” when you sneeze. You don’t have to say anything yourself. This is partly because sneezing is hard to stop.
However, you can usually stop your burps—or at least try to burp quietly.
In fact, it can be bad for your health to try to “hold in” your sneezes. Just make sure you cover your mouth and nose when you sneeze so you don’t spread (传播) any germs (细菌).
1. The underlined word “sneeze” means “________” in Chinese.A.打嗝 | B.打哈欠 | C.打喷嚏 | D.打呼噜 |
