阅读理解Boredom has become trendy. Studies point to how boredom is good for creativity and innovation, as well as mental health. It is found that people are more creative following the completion of a tedious task. When people are bored, they have an increase in "associative thought"—the process of making new connections between ideas, which is linked to innovative thinking. These studies are impressive, but in reality, the benefits of boredom may be related to having time to clear your mind, be quiet, or daydream. In our stimulation-rich world, it seems unrealistic that boredom could occur at all. Yet, there are valid reasons boredom may feel so painful. As it turns out, boredom might signal the fact that you have a need that isn’t being met. Our always-on world of social media may result in more connections, but they are superficial and can get in the way of building a real sense of belonging. Feeling bored may signal the desire for a greater sense of community and the feeling that you fit in with others around you. So take the step of joining an organization to build face-to-face relationships. You’ll find depth that you won’t get from your screen no matter how many likes you get on your post. Similar to the need for belonging, bored people often report that they feel a limited sense of meaning. It’s a fundamental human need to have a larger purpose and to feel like we’re part of something bigger than ourselves. When people are bored, they’re more likely to feel less meaning in their lives. If you want to reduce boredom and increase your sense of meaning, seek work where you can make a unique contribution, or find a cause you can support with your time and talent. If your definition of boredom is being quiet, mindful, and reflective, keep it up. But if you’re struggling with real boredom and the emptiness it provokes, consider whether you might seek new connections and more significant challenges. These are the things that will genuinely relieve boredom and make you more effective in the process.

阅读理解Have you ever wondered how acceptable it is to hug or touch someone? While it may sound safe to avoid all physical contact so as not to offend anyone, the lack of touching might imply cold attitudes or indifference in interpersonal relationships. So, what should we do? The simple answer is to thoroughly learn unique cultural norms for physical contact. In nonverbal communication terminology (术语), physical contact and the study of touching are generally referred to as haptics. Haptics in communication often suggest the level of intimacy. They are usually classified into two groups: high-contact and low-contact. Asia and quite surprisingly the United States, Canada and Britain belong to low-contact cultures. People from the rest of the world, such as Latin America, are considered to be in high-contact cultures, where they tend to expect touching in social interactions and feel more comfortable with physical closeness. Despite the classification, there are more complex factors such as relational closeness, gender, age, and context that can affect how someone views physical contact. One common French custom of greetings is cheek-kissing, but it is mostly restricted to friends, close acquaintances and family members. While cheek-kissing for Latin Americans is also a universal greeting form, it does not require such a high degree of relational closeness. However, gender matters more for them because cheek-kissing often only happens between women or a man and a woman but not two men. In contrast, in certain Arabian, African, and Asian countries, men can publicly hold hands or show physical affection as signs of brotherhood or friendship while these behaviors may suggest a romantic relationship in other parts of the world. Although men’s touching is more normal in these cultures, physical contact between persons of opposite sexes who are not family members is negatively perceived in Arabian countries. These factors could definitely affect the degree to which someone is comfortable with tactile (触觉的 ) communication and physical intimacy. Therefore, if you are someone who loves to show physical affection, you should not be afraid to show it or drastically change your behaviors—just ask for consent beforehand!

阅读理解Why it matters that teens are reading lessA) Most of us spend much more time with digital media than we did a decade ago. But today’s teens have grown up with smartphones. Compared with teens a couple of decades ago, the way they interact with traditional media like books and movies is fundamentally different.B) Analysis of surveys of over one million teens in the United States collected since 1976 reveals a major shift in how teens are spending their leisure time. Paper books are being ignored, in favor of screens. Digital devices are changing other behaviors, too. More and more, young people choose spending time on their electronic devices over engaging in other activities, regardless of the type. Indeed, by 2016, the average American high school senior said they spent six hours a day writing text messages, on social media, and online during their free time. And that covers just three activities, and if other digital media activities were included, that estimate would no doubt rise.C) Teens did not always spend that much time with digital media. Online time has doubled since 2006, and social media use has moved from a periodic activity to a daily one in the same period. By 2016, nearly nine out of ten young women in the 12th grade said they visited social media sites every day. Meanwhile, time spent playing video games rose from under an hour a day to an hour and a half on average. One out of ten American 8th grade students in 2016 spent 40 hours a week or more playing video games. Let me emphasize that this is equal to the time most adults spend per week at work.D) If teens are spending so much time using electronic devices, does that mean they have to give up some other activities? Maybe not. Over the years, many scholars have insisted that time online does not necessarily take away time spent engaging with traditional media or on other activities. Some people, they argue, are just more interested in certain kinds of media and entertainment. Thus, using more of one type of media does not necessarily mean less of the other.E) That may be true, but that still does not tell us much about what happens across a whole generation of people when time spent on digital media grows. Large surveys conducted over the course of many years tell us that American youth are not going to the cinema nearly as often as they did in the past. While 70 percent of 8th and 10th grade students used to go to the movies once a month or more, now only about half do this. More and more, watching a movie is something teens choose to do on their electronic devices. Why is this a problem? One reason is that going to the cinema is generally a social activity. Now, watching movies is something that most teens do alone. This fits a larger pattern. In another analysis, researchers found that today’s teens go out with their friends much less often than previous generations did.F) But the trends related to movies are less disturbing compared with the change in how teens spend their time. Research has revealed an enormous decline in reading. In 1980, about 60 percent of senior high school students said they read a book, newspaper or magazine every day that was not assigned for school. By 2016, only 16 percent did. This is a huge drop and it is important to note that this was not merely a decline in reading paper books, newspapers or magazines. The survey allowed for reading materials on a digital device.G) Indeed, the number of senior high school students who said they had not read any books for pleasure in the last year was one out of three by 2016. That is triple the number from two decades ago. For today’s youth, books, newspapers and magazines have less and less of a presence in their daily lives. Of course, teens are still reading. But they are generally reading short texts. Most of them are not reading long articles or books that explore deep themes and require critical thinking and reflection. Perhaps not accidentally, in 2016 reading scores were the lowest they have ever been since 1972.H) This might present problems for young people later on. When high school students go on to college, their past and current reading habits will influence their academic performance. Imagine going from reading texts as short as one or two sentences to trying to read entire books written in complex language and containing sophisticated ideas. Reading and comprehending longer books and chapters takes practice, and American teens are no longer getting that practice.I) So how can this problem be solved? Should parents and teachers take away teens’ smartphones and replace them with paper books? Probably not. Research has shown that smartphones are currently American teens’ main form of social communication. This means that, without a smartphone, teens are likely to feel isolated from their peers. However, that does not mean teens need to use electronic devices as often as they do now. Data connecting excessive digital media time to mental health issues suggests a limit of two hours a day of free time spent with screens, a restriction that will also allow time for other activities—like going to the movies with friends or reading longer, more complicated texts.J) The latter is especially important. I would argue that of all the changes brought about by the widespread use of digital devices, the huge decline in reading is likely to have the biggest negative impact on today’s teens because reading books and longer articles is one of the best ways to learn critical thinking. It helps people to understand complex issues and to separate fact from fiction. Thus, deep reading is crucial for being a good citizen, a successful college student and a productive employee. If serious reading dies, a lot will go with it.
