1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Deepfakes are videos which have been digitally manipulated (操纵) to show people saying something     1     they haven’t actually spoken. In the past, videos like these could be made only by     2     (experience) special effects artists or video editors. Now, anyone with the right tools can make a convincing deepfake.

These videos are easy to make and dangerous. Cases     3     (report) about misused deepfake technology in the past few months. So, how can we know whether what we are seeing and hearing is real?

Wael Abd-Almageed, who leads     4     team of five researchers at the University of Southern California, is trying to answer that question. This team has designed computer software which can determine whether a video is a deepfake. “If there is inconsistency (不协调) in the video, such as an unnatural eye     5     (move), we can spot it,” he said.

How can you avoid     6     (fool) by a deepfake? Wael Abd-Almageed suggests not     7     (immediate) believing what you see online. Instead,     8     (make) sure you research a video first. “Don’t take anything on the Internet for granted,” he warns. “Ask     9     (you), ‘Would this person really say something like this?’”

Wael Abd-Almageed also advises watching a video     10     a slower rate so you can spot inconsistencies. This is possible by using the settings on most popular video platforms.

3 . The rise of body neutrality You define (定义) beauty yourself. You are more than a number in measurement. Love yourself the way you are. Body positive messages like theses seem to be everywhere from social media to TV advertisements.

Body positivity’s aim to boost acceptance and appreciation of a variety of body types and sizes may explain why it has such a broad appeal. While some find the body positivity movement to be helpful, others have begun calling the movement toxic and suggesting it may be time to move on from this way of thinking.

More recently, people have voiced concerns. Some feel that the focus on loving your looks actually strengthens society’s stress on appearance over other values. Much body positivity content in advertisements may bring a stereotype (刻板印象) to viewers because it does little to challenge the hidden assumption that people are valued mainly for their appearance. Therefore, the movement still encourages people to be graceful and engage in beauty practices from head to toe. And if you fail to be body positive, it’s you that are at fault.

Many are now moving away from the body positivity movement and the pressures that come from it entirely, and instead are getting behind the body neutrality (中立) movement. Instead of focusing on physical appearance, body neutrality is a profound idea that we can exist without having to think too much about our bodies.

We are all more than just our bodies. We are complicated beings with a range of emotions and feelings about our bodies. And because body neutrality de-emphasizes (不强调) the focus on appearance, it motivates us to better acknowledge all the things our bodies are able to do. Being grateful for being able to take up your hobbies and appreciating your body for what it’s capable of doing are both examples of body neutrality.

Body neutrality can be beneficial to us. It is associated with the positive body image and mental well-being. The good news is that there are many ways you can develop body neutrality, including writing-based treatment, yoga and spending time in nature.

5 . 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.”

6 . Moving around Bogota can be a bit of a Jekyll-or-Hyde experience. On the one hand, the city is infamous (声名狼藉的)for having the world’s worst traffic. Yet, on the other, its cycling infrastructure is considered a good model of sustainable urban mobility, according to the Copenhagenize Index, which ranks bike-friendly cities. The Colombian capital generated a now-international movement in the 1970s called Ciclovia, which sees 1.5 million people cycle across 128km of car-free streets each Sunday morning.

So, when the pandemic reached its shores in mid-March, Bogota Mayor Claudia Lopez, an avid cyclist herself, introduced one of the world’s first plans to encourage bike travel, using traffic cones to create 76 km of temporary lanes.

“Everyone started using a bicycle, and they already knew how to get around on one because we have this bike culture thanks to the Ciclovia,” says Carlos Pardo, a local cycling advocate and senior advisor at the New Urban Mobility Alliance. Pardo got involved at the beginning of the pandemic by partnering with a local bikeshare company to provide 400 free e-bikes to health workers. Now, he’s busy persuading the public that the government’s new bike lanes should become permanent fixture (固定设施).

“Some drivers say, ‘you took away our lane’, but we’re saying, we took one car lane and made a two-lane bidirectional bike lane,” he explains. “So, you’re duplicating the effectiveness of the space, and moving more people per hour, per direction.”

Biking has enjoyed a renaissance (复兴) around the world as urban citizens avoid public transport for the relative safety of a two-wheeled commute. Now, many advocates like Pardo are working with local governments in the hope of turning these pandemic-response measures into lasting changes—ones that are more plausible now than ever after lockdowns provided an unprecedented (空前的)opportunities to fast-track infrastructure trials. The results of these urban planning experiments could not only radically shape the way we commute across global cities, but also make them more adaptable to future shocks.

7 . My phone was an extension of myself. I couldn’t go anywhere _________ it. I scrolled through my friends’ _________ into late night and turned my phone on before my eyes were fully open. I enjoyed having it until that day when I realized that what had started as a useful tool had turned into a(n) _________. So, I made a _________ decision to turn off that smartphone and _________ my old dumb phone out of hiding.

When I was watching TV shows or movies and there was a boring part, I _________ picking up the phone and checking out “what everyone else was doing.” Now I had to pay attention or find a way to _________ myself with my thoughts instead.

I have welcomed silence into my life with open arms and am enjoying the increased __________ from not constantly having to fight with the __________ to check my phone while I’m trying to get something done. I am allowing my thoughts to speak to me instead of my phone. I am connecting with others in a __________ way that isn’t all about me. Instead of always posting about what’s going on in my __________ perfect life, I am connecting with my friends one-on-one, talking about the reality of our lives and being there for them from a place of __________.

As much as having a smartphone was __________, not having one is freeing on a much bigger level.

9 . What comes to mind when you think about chocolate? A candy bar at Halloween? Ice cream on a hot day?

For Ibrahim, a 12-year-old boy from the West African country of Ghana, chocolate is not about sweet treats; it is about bitter work.     1     But if they did, we would learn that Ibrahim spends his days growing and harvesting cocoa beans, from which chocolate is made. We would also learn that he is just one of more than two million children who perform this difficult labour instead of attending school.

To change the harmful practices like this, some farms use an approach called Fairtrade.     2     It aims to create a different relationship between buyers (chocolate companies) and sellers (cocoa farmers) by encouraging farmers to join together to form a shared business called a cooperative. Because farmers work together instead of competing with each other, they can demand a higher price from the buyers.     3    

Consumers like you can play a role as well. You can buy Fairtrade chocolate if possible, pressure candy companies to change their labour practices, or ask local stores to sell Fairtrade products.     4     It is a programme recognizing schools that provide Fairtrade products in cafeterias or include related lessons in curriculum (课程).

Chocolate has a hidden story that affects children like Ibrahim—children who want a happy future just like you do.     5     By enjoying Fairtrade products or simply spreading the word, you can make chocolate as sweet for all children as it is for you.
