【推荐1】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. |
| I worry about my boys. They waste a lot of time in front of the computer playing games. I'd rather they read or ran around outside. How can I limit(限制)the time my children spend playing games? Mrs Smith |
| It might be best if you let the kids play games before doing their homework.Research shows that it's not a good idea to play them before going to bed, since they keep the kids from sleeping well, and that playing them after a learning activity can mitigate(减轻)the brain's ability. Alpreesh |
| My kids are only allowed to play computer games at the end of the school week and only after they have done their homework. It's very clear to them, and they have accepted the rule happily. We have no more arguments during the week. It's really been good for us. Cage |
| I personally find it difficult to set time limits but when they’re on the computer,I get some quiet time. I built and now use a simple timer program that lets me set time limits(like 1 hour each day). The program gives the kids an audible reminder like "5 minutes left", and they have to stop when their time is up. It has ended all the fighting over computer time in our house.

【推荐3】Are You Smarter Than a 5th Grader? is a new trivia quiz（问答） show video game. You can play it on the computers, Nintendo Switch, PlayStation, and Xbox consoles.
The game uses the ideas of a TV show. This TV show first appeared in 2007. It tried to test people on information they learned in primary school. Only a few players ever won the big prize of ￥1 million.
There were eleven different questions in the game of the TV show. Two each from first through fifth grade and one from sixth. Every player can ask “classmates” for help three times.
In the TV show, those “classmates” were real students. In the video game, the classmates are computer-controlled（控制） characters.
The video game has two main modes （模式）: Exam and Study. In the Exam mode, only one player can join it. The player tries to answer all the eleven questions. The questions get harder as you go along. If you need help, you can use a classmate’s answer, ask the class for help, or ask the host for a new question. Every classmate is good at different subjects. When you get points, you can ask more students for help and answer more new subjects and questions. There are 6, 800 questions in all.
In the Study mode, up to eight players can test what they learned at the same time, so you’ll be able to play with friends and family. Your real-life school experience can help you get ready for the game.

The following information is about four sports of the ancient city Xi’an.
Cuju（蹴鞠）is an ancient game in which players kicked a ball into a net. It was very popular during the Han Dynasty. Emperor Hangaozu Liu Bang not only liked watching cuju games, but always played it. The earliest record of women cuju players was also from the Han Dynasty.
Jiju（击鞠）was a popular sport in the Tang Dynasty. In the game, players used sticks to hit a ball while riding on horses. In the Tang Dynasty, there were lots of fields for playing. In the capital, there were formal courts for jiju games.
As early as the Zhou Dynasty, archery（射箭）was one of the Six Arts. And formal competitions were held during the Tang Dynasty. Archery was an important part of the wuju examinations, and five kinds of archery skills would be tested.
Ancient jueli is a Chinese-style wrestling（摔跤）. During the Sui and Tang dynasties, jueli was preferred by emperors. In the Tang Dynasty, there were professional wrestling teams. Wrestling competitions were usually held twice a year in spring and autumn.

【推荐3】The United Nations World Tourism Organization (UNWTO) and the Spanish government have announced that Chinese has become an official language of the UNWTO since Jan. 25.
That means the organization will use the Chinese language, increasing China’s soft power in global tourism and the cultural domain (方面). It will help China’s tourism growth, encouraging other countries to carry out its policies (政策). Tourist places in China will also welcome more visitors, encouraging more people globally to learn the Chinese language. China’s influence on the cultural and tourism domains will surely grow.
There are two main reasons for that. First, Chinese governments have been promoting Chinese culture for long. As far as in 2016, the Spring Festival was listed as a national cultural heritage (遗产) and given special protection and promotion. Now, there are many influential festival lists in the world and almost all of them list the Chinese New Year, or the Spring Festival; many even list it at the top.
Second, the year-on-year growth in the number of Chinese tourists before 2020 has also played a part in promoting the Chinese language and culture. In 2019, the number of foreign visitors in China were more than 670 million. That means Chinese faces have become common at tourist places in the world.
Although the data for 2020 have not been published yet, the numbers are expected to have fallen because of the outbreak(爆发) of COVID-19. But with China’s great efforts in stopping the virus from spreading, the number of tourists might still be larger.
Chinese language has now become a world language in tourism. That has a lot to do with China’s improving economy and people’s rising income (收入). With China’s growth, it is hoped that its influence on other soft power domains will also grow.
1. Paragraph 2 mainly tells us ________.| A．how to encourage foreigners to learn Chinese |
| B．why Chinese is widely used around the world |
| C．about the famous tourist places around China |
| D．the advantages of Chinese as a tourism language |
| A．discussing | B．spreading | C．admiring | D．researching |
| A．Official Languages of the UNWTO. | B．China’s Tourism Growth. |
| C．Chinese-A Tourism Language Now. | D．A National Cultural Heritage. |
【推荐1】Imagine this. There’s an apple and a piece of cake on a table. Which one would you like? The delicious cake or the healthy apple? A bestseller, Willpower: Rediscovering Our Greatest Strength, suggests that willpower (意志力) is the ability to make decisions that are better for us in the long term, rather than in the short term.
Here is a famous experiment in the book: The Marshmallow Test. In 1972, Professor Walter Mischel tested the willpower of 600 four-year-olds to six-year-olds. In the experiment, each child was left alone in a room for fifteen minutes with a marshmallow (棉花软糖) on a table in front of them. They were given two choices: they could either eat it or, if they waited fifteen minutes, they’d be given a second one (and then they could eat both).
So, what did the kids do? Well, as you can imagine, 70% ate the first marshmallow within the fifteen minutes. But the other 30% showed willpower—they controlled themselves and waited for the second marshmallow. But then Mischel discovered something really interesting. Twenty years later, he got in touch with the children, who, by then, were in their early twenties. And he found that those who’d had strong willpower were getting better marks at university and were more popular.
Willpower is like a muscle (肌肉), and the more you exercise it, the stronger it gets. So, if you do daily “self-control exercises”, such as making your bed or brushing your teeth, you’ll improve your overall willpower. And daily willpower exercises will help you with those bigger goals, such as studying for an exam or training for a marathon.
Be careful though. Just like any muscle, your “willpower muscle” can get tired. If you’ve had to do lots of things that require willpower, take a break or give yourself a treat. That way, you’ll build up your willpower again.
And one last thing, the writer mentions people who learn foreign languages usually have a lot of willpower. So, congratulations!
