1 . While screen time is known to affect sleep, new research suggests that interactive (互动的) activities, such as texting friends or playing video games, put off and reduce the time spent asleep to a greater degree than passive (被动的) screen time like watching television, especially for teens.

The team studied the daytime screen-based activities of 475 teenagers using daily surveys. They asked the teens how many hours they had spent that day communicating with friends through social media and how many hours they spent playing video games, surfing the internet and watching television or videos. Finally, the researchers asked if they had joined in any of these activities in the hour before bed.

Next, the team measured their sleep time for one week. The researchers found that the teens spent an average of two hours per day communicating with friends via social media, about 1.3 hours playing video games, less than an hour surfing the internet and about 1.7 hours watching television or videos. For every hour throughout the day that they used screens to communicate with friends, they fell asleep about 11 minutes later averagely. For every hour to play video games, they fell asleep about 9 minutes later. Those who talked, texted or played games in the hour before bed lost the most sleep: about 30 minutes later.

Interestingly, David, lead author of the study, said the team found no obvious relations between passive screen-based activities and sleep. “It could be that passive activities are less mentally exciting than interactive activities,” said Anne, co-author of the study. “It’s a tricky situation,” she said. “These screen tools are really important to everyone nowadays, so it’s hard to put a limit on them, but if you’re really looking out for a teenager’s health and well-being, you might consider limiting the more interactive activities, especially in the hour before bed.”

2 . You see a shopper trip over in a busy street. Someone else can help. That’s what you tell yourself. This is the bystander effect in action — the dilution (淡化) of responsibility in the presence of others — and it has been demonstrated in many past studies.

But life is complicated and psychologists have seen exceptional circumstances. Two experiments were conducted by Marco van Bommel and his team using an online chat room for people with extreme emotional problems. Eighty-six students were logged into the forum (论坛) and shown five messages from troubled users. They were told to write a reply if they wanted, but it was entirely up to them.

Basically, participants could see their names on the screen alongside others’ names. A counter also told them if the forum was quiet, with just one other person logged in, or busy, with 30 others online. This arrangement reproduced the classic Bystander Effect-participants were less likely to post replies with more people logged in. However, when the researchers cued (提示) self-awareness by highlighting participants’ names in red on the screen, they posted more replies on a busy forum.

A second study was built on these findings, but this time self-awareness was raised by the presence, or not, of a computer web-camera. Over 100 participants took part. Although told the camera wouldn’t be used until later, those with cameras were asked to check the camera’s indicator-light during the study. The Bystander Effect was reproduced when web-cameras were absent-on busy forums participants posted fewer replies to needy users. By contrast, those cued to be self-aware by the web-cam actually wrote more replies.

Nearly any online community can benefit from the research. The ability to turn hesitant bystanders into eager helpers is a recipe for engagement and collective benefit. As in the research, simple design cues could be integrated to help online users remember they are visible to the community. For example, the size of profile images and specific on-site reminders can be used to highlight how users see themselves within the community.

1. What does the underlined word “it” in paragraph 1 refer to?

A．The hidden danger of a busy street.

2. In the first study, the participants posted more replies to the troubled when

A．there were more emotional problems

B．the counter indicated the forum was quiet

C．their presence was reminded on the screen

D．more individuals were logged in the forum

3. Why is the web-camera used in the second study?

A．To encourage more replies.

B．To reproduce the bystander effect.

C．To further test participants’ mindset.

D．To better record participants’ actions.

4. What strategy can online communities learn from the research?

A．Working together to attract more users.

B．Combining designs to boost users’ memory.

C．Building more platforms for public promotion.

D．Exploring ways to change bystanders into upstanders.

4 . Being healthy is important. Often, we’re crazy about articles in health magazines talking about the latest popular diets, or advertisements that offer cures (疗法) for fatness that are often too good to be true. One of the latest crazy phenomena (现象) is intermittent fasting (间歇性禁食).     1    

There are different ways of intermittent fasting.     2     Another common way is choosing a diet that sees people only eating during a limited part of the day, for example, over eight hours.

    3     A study suggests intermittent fasting may help control blood sugar and reduce the possibility of suffering related disease. Other studies have shown intermittent fasting may help slow the ageing process, support brain function, lose weight, etc.

Some people try intermittent fasting for weight management, and others use the method to deal with some conditions such as high cholesterol or arthritis.     4     Fasting might not suit those who are underweight or with a long-term medical condition. Fasting may cause some people to experience symptoms (症状) such as headaches or make them easily suffer from overeating after a reduced calorie intake (热量摄入) day.

As with many diets, it’s always wise to speak to your doctor or weight-loss professional before changing your eating habits. And, at the end of the day, it could just come down to what lifestyle choice suits you.     5     If not, your health may suffer.

A．But what is intermittent fasting?

B．However, this diet isn’t for everyone.

C．Intermittent fasting has two main origins.

D．Let’s look at some of the possible benefits.

E．The idea of this is to reduce calories over a period.

F．In a word, you should avoid turning to intermittent fasting blindly.

G．You can eat normally on five days of a week and reduce calorie intake on the other two.

7 . People these days are posting about their lives on social media. But what if you’re a private and introverted person like me? What if you want to live in the moment instead of sharing every bit of your life? To be honest, it’s nobody’s business but your own.     1    

Escaping stalkers (跟踪者).

I’ve been a public person as a jazz vocalist for years. It exposed me to stalkers who felt they knew me, just because I was present everywhere. Needless to say, it brought me much anxiety and stress. At some point I asked myself-is being visible more important than my peace of mind?     2     The answer is a clear NO. I just want to spend life doing what I love with the people I love.

Protecting privacy

    3     I need alone time to process what I’m struggling with and honest real talks with the people I trust. I might share a lesson learned from an experience, but now I won’t. I know that by keeping my life private on social media I may miss out on some connections, but I honor and respect the people in my life who value their privacy, so I am being mindful and protect that.

    4    

Another reason I keep my life private is that I prefer to be in the present moment and appreciate it fully. To be on your phone constantly, or to film everything you do, can be quite disrespectful to the people you spend your time with. You lose out on those spontaneous(自发的) moments and a deeper connection. I choose what I share and when I share it, and the rest is for experiencing life without expectations.

Live your life fully, regardless of whether the world knows it or not!     5     I just want you to know it’s OK if you don’t.

A．Experiencing life

B．Living in the moment

C．Don’t I really care about privacy?

D．Are my followers more important than my friends and family?

E．If you feel like sharing your life openly without hesitation, go for it.

F．Here are my reasons for not sharing my personal life on social media.

G．It can be quite challenging to go through tough moments with everyone watching.
