As a small children in primary school, I enjoyed sport very much. I could play freely. Move on to high school marked a big change in this respect. I was no longer encouraging to play with friends at a break. Instead, I sat and chatted, or if I particular wanted to learn I studied. As a teenager, I became more aware about what other people thought of me or how I looked. Sport became something I have to do to stay healthy and pass my PE test. The fun element had taken away from it. Last year, I practiced yoga, that has helped me change my attitude towards sport.

【題目】Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.

Today, the events 【1】 in realistic-looking or-sounding video and audio recordings need never have happened. They can instead be 【2】 automatically, by powerful computers and machine-learning software. The catch-all term for these computational productions is “deepfakes”.

The term first appeared on Reddit, a messaging board, as the username for an account which was producing 【3】 videos. An entire community 【4】 up around the creation of these videos, writing software tools that let anyone automatically 【5】 one person’s face onto the body of another. Reddit shut the community down, but the technology was out there. Soon it was being applied to political 【6】 and actors.

Tools for editing media 【7】 have existed for decades—think Photoshop. The power and peril of deepfakes is that they make fakery cheaper than ever before. Before deepfakes, a powerful computer and a good chunk of a university degree were needed to produce a realistic fake video of someone. Now some photos and an Internet connection are all that is required.

The consequences of cheap, widespread fakery are likely to be 【8】, albeit slow to unfold. Plenty worry about the possible impact that believable, fake footage of politicians might have on civil society—from a further loss of trust in media to the 【9】 for electoral distortions. These technologies could also be deployed against softer targets: it might be used, for instance, to bully classmates by creating imagery of them in embarrassing situations. In a world that was already saturated with 【10】 imagery, deepfakes make it plausible to push that even further.

【題目】

When it comes to food coloring, why should we have to prove just exactly how and why the substance causes a negative effect on the people who consume it before we can 【1】 it ? If this were a necessary or meaningful food ingredient (材料) in any way, sure, that would be a reasonable standard. But food coloring has no nutritional value. Why are we 【2】 it?

Most likely because it helps companies sell products. Pretty food pays off because aesthetics (美學(xué)) in food does 【3】. We have relied on 【4】 cues (暗示) for thousands of years to help us determine what is edible, nutritious, and safe to eat. Man has adapted to appreciating natural colors, including a varity of green, red, pink, orange, yellow, and purple produce. Colors 【5】 that food is ripe (成熟的) or that it contains healthy compounds. Because of that 【6】 background, color is money for food manufacturers. Children are especially attracted to a variety of bright, vibrant colors and succumb to (屈從于) targeted marketing.

Food aesthetics can also affect how we look at taste. In one study, when subjects were given sugar water in different 【7】 of red, they reported that the deep red drinks tasted sweeter than the light red ones. We’ve been programmed to expected certain things from certain colors. Another study showed people had a harder time 【8】 drink flavors when the drinks did not have the expected colors. We expected what nature has taught us, and even though our food system has changed dramatically in the past several decades, our expectations have yet to 【9】 up. Food companies can instead use this knowledge to 【10】 us and make their processed products appear more delicious.
