1 . Many parents of both boys and girls have witnessed striking differences in the way their kids use technology, with their sons generally gravitating to videogames and their daughters often spending more of their screen time scrolling through social media. Emerging research indicates that brain differences between males and females help account for the split.
Marc Potenza, a professor at Yale University, teamed up with researchers at universities in China to find out why. Using functional MRIs, which measure brain activity by detecting changes in blood flow, the team studied neural responses in young male and female gamers, particularly in the parts of the brain associated with reward processing and craving --a motivating factor in addiction. When the men and women were shown photos of people playing videogames, those parts of the men’s brains showed higher levels of activation than those parts of the women’s brains.
Brain regions that have been implicated in drug-addiction studies also were shown to be more highly activated in the men after gaming. The researchers said the results suggest men could be more biologically prone (有倾向的) than women to developing internet gaming disorder.
But girls and women aren’t free from problems when it comes to digital media. Data from Pew shows that, in general, women use social platforms such as Facebook, Instagram and Pinterest far more than men. Many girls and women are drawn to those photo-sharing sites because they like to form bonds and find similarities, says Rosanna
Guadagno, a social psychologist at Stanford University. Some recent studies show that girls feel the ill effects of too much social media use, such as depression and anxiety, more than boys do.
Researchers at the University of Zurich looked at how differences in brain functioning can help explain why women tend to be more prosocial—that is, helpful, generous and cooperative—than men. In the 2017 study, they hypothesized that the areas of women’s brains related to reward processing are more active when they share rewards and that those areas in men are more active when receiving, selfish rewards. Brain scans conducted on men and women, in which they chose between receiving a monetary reward only for themselves or one that involved sharing money with others, supported their theory.
Scientists say understanding those differences is critical to parents’ ability to help kids navigate the fast-changing world of tech.

5 . During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street — so I can focus. ” His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.
Why does the interviewer prefer a coworking space?
| A．It helps him concentrate. |
| B．It blocks out background noise. |
| C．It has a pleasant atmosphere. |
| D．It encourages facetoface interactions. |
6 . People have been pouring into stadiums since the days of ancient Greece. In around 80 A. D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.
How many people could the Circus Maximus hold?
| A．104,944. | B．107,601. |
| C．About 150,000. | D．About 250,000. |
7 . The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
