Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like James Bond in the movie Casino Royale? Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond’s wonderful performances that the sport has become popular worldwide.

Yes, that’s parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the barriers in the path using only the abilities of the human body. Parkour is considered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.

Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.

Overcoming all the obstacles on the course and in life is part of the philosophy behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back in your life, to reach the destination successfully. A parkour lover said, “I love parkour because its philosophy has become my life, my way to do everything.”

Another philosophy we’ve learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself.

And the heavier users of social media get to bed later and get poorer quality sleep. The new study was based on self-reported survey data from nearly 12,000 teenage participants in the U. K. Millennium Cohort Study.

Megan Moreno, a researcher at the University of Wisconsin Madison, says social media is too often described as either entirely good or bad, when the reality is more complicated(复杂的) for teens. Social media may have its problems, but it is the way that they stay in touch with each other,” she says.

Perhaps unsurprisingly, the study found a link between high social media usage and poor sleep patterns. Especially, teens who are heavier users of social media go to sleep later. And the researchers note late bedtime is linked with poorer academic and mental health consequences.

Holly Scott, a researcher at the University of Glasgow, isn’t sounding the alarm. She says, “It’s easy to look at the results of this and think, ‘We should just get teenagers to spend less time on social media. ‘ I think that’s an understandable response, but what I really encourage people to do is look beyond that. “ She says people should pay attention to the important emotional ,cognitive (认知的)and social factors when teenagers are using social media.

Scott stresses that the study is pointing to a connection between social media and poor sleep, but not necessarily explaining cause and effect.

“Certainly some teens do say they struggle to get away from social media at night - they might be worried about missing out on things, or affecting their friends by not answering messages -and they stay up late for that,” she says. “As for some of those young people, they have a naturally later body clock and they are passing their free time at night on social media until they^’e ready to fall asleep.”

【推荐2】Raising livestock (牲畜) is a big part of the carbon emission from agriculture. But it is hard to change people’s habits and get them to give up their hamburgers, especially since more than one-third of Americans eat fast food every day. We previously called for carbon labels on everything from buildings to burgers. Now, a new study from the Johns Hopkins Bloomberg School of Public Health found that labels on fast food affected people’s choices.

The study said shifting current dietary patterns to more sustainable diets with less red meat could reduce food-related greenhouse gas emissions by 55% and have health benefits.

The 5,000 participants in the study were shown fake menus. One group got menus with high climate impact labels on red meat items and another had low climate impact labels on fish or plant-based burgers. Both menus were effective in reducing the orders for red meat. But interestingly, the high-impact labels were far more effective, with 23% of the participants choosing a more environmentally sustainable selection, while menus listing low-impact choices encouraged only 10% participants to change.

“We found that labeling red meat items with high-climate impact labels was more effective in increasing sustainable selections than labeling non-red meat items with low-climate impact labels,” wrote the authors of the study.

Lead author, Julia Wolfson, said, “These results suggest that menu labeling, particularly labels warning that an item has high climate impact, can be an effective strategy for encouraging more sustainable food choices in a fast food setting.”

The study points out negative labels might be unpopular: “It is unlikely that the industry would voluntarily adopt a negative label approach; such an approach needs to be carried out via law. However, high climate impact labels may easily be adopted in settings like universities and hospitals.”

They have a point that this label is aggressively negative, more like a cigarette warning than a food label. In the study, the authors note that future research should test more label designs using qualitative and quantitative research on how people understand different climate impact labels.

1. What is paragraph 1 mainly about?

A．The background of the new study.

B．The influence of the carbon emission.

2. How did the groups respond to the menus?

A．They liked them very much.

B．They stuck to their preferences.

C．Some of them stopped eating fast food.

D．Some of them changed their food choices.

3. What can we learn about carrying out the approach from the text?

A．It will be banned by law.	B．It will produce bad results.
C．It will face some resistance.	D．It will be accepted by all industries.

4. What does the author mainly want to convey in the text?

A．Fast food has a negative effect on climate.

B．Raising livestock surely causes carbon emission.

C．Researchers care too much about climate impact.

D．Labels on fast food can help protect the environment.
