1 . In our information-driven society, shaping our worldview through the media is similar to forming an opinion about someone solely based on a picture of their foot. While the media might not deliberately deceive us, it often fails to provide a comprehensive view of reality.

Consequently, the question arises: Where, then, shall we get our information from if not from the media? Who can we trust? How about experts- people who devote their working lives to understanding their chosen slice of the world? However, even experts can fall prey to the allure of oversimplification, leading to the “single perspective instinct” that hampers (阻碍) our ability to grasp the intricacies (错综复杂) of the world.

Simple ideas can be appealing because they offer a sense of understanding and certainty. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple that way.

Yet, when we embrace a singular cause or solution for all problems, we risk oversimplifying complex issues. For instance, championing the concept of equality may lead us to view all problems through the lens of inequality and see resource distribution as the sole panacea. However, such rigidity prevents us from seeing the multidimensional nature of challenges and hinders true comprehension of reality. This “single perspective instinct” ultimately clouds our judgment and restricts our capacity to tackle complex issues effectively. Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you would like to understand reality.

Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, consult people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. If this means you don’t have time to form so may opinions, so what?

Wouldn’t you rather have few opinions that are right than many that are wrong?

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

6 . As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?

Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the ever－rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.

The other underlying question, of course, is “does it really matter if the written word bows to the world of film/TV?” From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain’s most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.

It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.

Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.

7 . Concerns about the harm caused by “too much” screen time—particularly when it is spent on social media—are widespread. But working out what a “healthy” ___ might be is far from easy.

Some negative experiences on social media—like ____ how your appearance compares to others—do affect some children. However, this does not mean that technology use in ____ is harmful and it is difficult to make claims about how it will affect different people.

Consider the picture painted by a UNICEF review of existing research into the effects of digital technology on children’s ____ comfort, including happiness, mental health and social life. Rather than stating that social media was harmful, it suggested a more ____ effect.

The UNICEF report highlighted a 2017 study that examined 120,000 UK 15-year-olds. Among those teenagers who were the lightest users, it was found that increasing the time spent using technology was linked to ____ comfort—possibly because it was important for keeping up friendships. ____, among the heaviest users of technology, any increase in time was linked to lower levels of comfort. Overall, the UNICEF study suggested that some screen time could be good for children’s mental health.

A broader look at evidence provided by some other high quality studies again suggests the story is not ____. An early study in 2013 looked at how the television and video game habits of 11,000 UK five-year-olds affected them two years later. It is one of few studies actually ____ the effects of technology over time. It suggested that, compared with children who watched one hour of television or less on a weekday, a small increase in conduct problems was seen among those who watched more than three hours each day. Playing electronic games, however, was not seen as leading to a greater ____ of friendship or emotional problems.

So how much time should our children spend looking at screens? It is difficult to be ____ as different people spend time online in such different ways. A useful comparison might be with sugar. Broadly speaking, people ____ that too much sugar can be bad for your health. But the effect it might have can depend on many factors, from the type of sugar to the person and the amount. We would not ____ trust anyone who claims to predict how someone is affected by consuming one gram of sugar. The same could be said for ____ usage: the outcomes depend on so many factors that only very ___ predictions are possible.

8 . If you’re reading this, it’s safe to assume you arrived by internet.

Maybe you caught the headline as it raced by on Twitter. Or you might be taking a break from watching a boring movie on Netflix.

It doesn’t matter. Because according to a new study, it all adds up to the same thing: one distraction（分心的事情）after another.

And the thing is, they’re welcome distractions. Because, as the research — published this week in the Journal of Personality and Social Psychology — notes, people will do just about anything to avoid being left to their own thoughts.

For their study, researchers designed a sample test for more than 2,557 participants in 11 countries. They divided their test subjects into two groups. In the first group, people were asked to spend 10 to 15 minutes “entertaining themselves with their thoughts as best they could.”

Just sit back and think about things. Sounds good, doesn’t it? Well, not really. The second group — the one where people were told to surf the Net, play a video game, or even read a book — reported having much more fun. They scored more highly on entertainment and lower on boredom. And the preference for distraction seemed to be a global phenomenon, which may come as a surprise to Italians who are famously brilliant at doing nothing.

“The preference for doing external（外部的）activities such as reading, watching TV, or surfing the internet rather than ‘just thinking’ appears to be strong throughout the world,” the researchers note in the study.

But there does seem to be an important thing that hasn’t been included in the study. Shouldn’t the quality of thoughts matter? If you’ve got something positive to think about — say, how you’re going to spend your vacation or the great screenplay you’ve already half-written in your head — why are you reading this?

On the other hand, if you are always bothered by negative thoughts — a sad or painful experience, perhaps — by all means, keep scrolling（翻网页）.

Unfortunately, we won’t be able to take up much of your time here; it’s a short study that gets to the point in a hurry. Don’t worry though. There’s a whole world of distractions out there. Say, have you seen that ship teetering at the brink of Niagara Falls? And how about those charming cows? Bet you didn’t know they could smell you from six miles away.

And that’s something to think about.

9 . Did you ever have to say “no” to somebody? Such as a classmate who asks to go to lunch with you? New research suggests that, at least socially, a rejection (拒绝) should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.

Gili Freedman is doing some related research at Dartmouth College. For her research, she asked over 1,000 people to respond to different examples of social rejection. In one example, the researchers asked people for their reaction (反应）after a person named Taylor asked to join a co-worker who went out to lunch every Friday. And Taylor was told “no”. But in some cases, the person rejecting Taylor offered an apology. In other cases, the people doing the rejection did not say they were sorry. People were asked how they would feel if they were being turned down, just as Taylor was. Most said they would be more hurt by a rejection with an apology than a rejection without an apology.

Freedman said the reason is that apologies make people feel like they need to say that the rejection was okay— even when they felt like it was not okay. Rejection without an apology lets them express their feelings of disappointment, hurt or anger more easily. Freedman also said that an apology often makes the person doing the rejection feel better—even as it makes the person being rejected feel worse.

Her research deals only with social communication. A business situation might be very different. “If a manager rejects a job interviewee or a boss must tell an employee that he or she is being fired from a job,” Freedman said, “reactions to apologies may be different.”

10 . Many small-business owners watched recent revelations about Facebook with mixed emotions. Like most Americans, they were surprised to discover how much information the social media giant collected on its users. But when it comes to small business, Facebook is a transformative advertising platform for small businesses, not easy to replace.

Let's say you own a small seafood restaurant, and Tuesday nights are $1 oyster （牡蛎）nights. Traditional advertising methods cost a lot and must be planned long in advance, and ifs hit-or-miss as to whether you actually get in front of oyster eaters. With Facebook, on Tuesday morning, with a few clicks, you can target Facebook users in your Zip code who love oysters and eating out （and are over age 21, so they can buy drinks, which is why you have $1 oyster nights）. And you can do this for as little as S20.

In my work with small businesses for more than 25 years, I've never seen a more effective method of micro-targeting prospects. Though Facebook is an effective tool for small-business, advertising does not justify （证明合理）the company's collecting vast amounts of data or allowing users' data to be invaded.

"Our primary concern was people's experience on Facebook," said Dan Levy, Facebook's Vice President. "Our teams have also been speaking to small businesses, and they want to make sure we're addressing the situation, and we are."

One concern small businesses want Facebook to address is protecting their uploaded lists. No one wants their customers' information misused or accessed by others, especially competitors.

Small-business owners are rightfully concerned about privacy. They don't want Facebook to know everything about them, and they don't want their customer lists to be let out to others.

But small businesses don't want to lose this effective advertising medium, either. Most Facebook ads are not invasive or offensive. And many receivers may actually benefit from receiving highly targeted ads—after all, those oyster lovers like learning about Tuesday night— $1 oyster night.
