1 . My wife and I parked by a rough path the same time as a young man covered in tattoos (纹身). I ______ he was unfriendly，so we tried to ______ ourselves from him. But he struggled hard to ______ and wanted to talk some. We slowed down. He said he was recovering from a bad time in his life. We ______ left him in the dust，heading up the river.

Hours later we turned back ______ a flash flood had taken out the bridge. There he was again, following to ______ us. He shared a little more of his ______. He lost his mother and sister in a car accident and he was permanently ______ too. We slowed down to the pace he could ______ for the whole way back.

He continued, “During much surgery and ______ I came to hate life...” Then he pulled up his shirt to show us a ______ life size tattoo from neck to waist. It was two ladies in a ______ light waving to him. “This is my mom and this is my sister,” he pointed, “They told me to stop hating everything. They loved me just as they always had and ______ me to live in love too!” He explained the brightly colored tattoo was the exact dream he had that day.

My ______ went away. It had painted a wrong picture of this wonderful person with a beautiful ______ . I learned more than he hoped to tell.

The power of Chinese emperors rose and fell with their control of the Grand Canal. Today, this waterway is shorter than it was once,     1     it is still the longest man-made river in the world.     2     (important), the Grand Canal continues to provide a vital cultural and economic link for modern China.

The original Canal system began around the year 605,     3     China’s emperor Yang realized that he needed a better way to move food and feed his army, so the emperor ordered the construction of the first section of the Grand Canal,     4     (connect) those existing canals, lakes and rivers.

For more than a thousand years, goods     5     (transport) along the Grand Canal. Even today the country’s watery highway plays an important economic role in China. Boats continue to carry tons of coal, food and other goods     6     Hangzhou and Jining. However, local governments eager to increase     7     (tour) and city development have torn down almost all of the older canal-side buildings. In 2005 a group of citizens proposed that the historic Grand Canal be made     8     UNESCO world heritage site, hoping this status would protect both the waterway and the architecture around it. With UNESCO status officially     9     (grant) in 2014, the world’s greatest engineering accomplishments continue to link north and south China for     10     (century) to come.

4 . Imagine driving behind a huge truck shooting clouds of smoke into the air while your new fully electric vehicle cleans up its carbon emissions (排放). This dream may soon be a reality. A team of students in the Netherlands has created an electric car that not only doesn’t produce carbon dioxide when driving, but actually pulls it out of the air.

The two-seater sports car was designed and built in less than a year by a team of 32 students at Eindhoven University of Technology. Called “ZEM”, which stands for “zero emission mobility”, the car is equipped with special devices that remove carbon dioxide from the air as it drives. The team says if ZEM is driven about 32,000 kilometers, it can remove 2 kilograms of carbon dioxide from the air. That’s not a huge amount. The team calculates that 10 ZEM cars on the road for a year would remove as much carbon dioxide as a typical tree does during that time. However, they also point out that there are over a billion passenger cars in the world that could be using this technology. And if a billion cars were removing carbon dioxide instead of producing it, the result would be huge.

ZEM also has several other innovations that help to make it more capable of being sustained: the car’s frame and panels (面板) are 3D printed to reduce waste; it was built using recycled and recyclable materials; and it can be easily taken apart so that many of its parts can be reused. ZEM’s battery is also reusable, and has another handy feature: it can be charged with solar panels on the car’s roof—and can even be used to provide power to your house when the car isn’t on the road.

According to the statistics, transportation was responsible for over 20% of global carbon dioxide emissions in 2020—and of those emissions, cars were responsible for 41%. The Eindhoven team says its goal is to challenge the electric car industry: If 32 students can build a car like this in less than a year, then surely car manufacturers (生产商) are expected to adopt these innovations, too.

5 . While enjoying my fresh lunch in a restaurant in Amsterdam, I noticed something odd. Customers coming in for something to eat ignored the person standing behind the counter (柜台), preferring to________through a smart phone.

What was the crazy thing about this? They were just several________apart! In fact, they were so close that the staff member took a quick________at his screen to get a head start on picking the right vegetables—all without any words________. Now, I get it: Modern technology allows us to be more________, but I might be witnessing something deeper: we prefer not to talk to each other anymore.

Think about it for a moment. When was the last time you naturally ______ a conversation with somebody you didn’t know? The chances are that you don’t even________! Likely either you or the other person was “busy” with other things like________with a smartphone. Now, with the________of digital technologies, one can’t help but pay the________for modern efficiency: our ability to talk to strangers.

We shop,________a hotel, or order a taxi, all via an app.________with random strangers is becoming rarer and rarer. Yet there are surprising________of having even a short and simple conversation with strangers. You might learn something________, and beyond doubt, it has the power to enrich your understanding of others and________a special bond in our modern world.

6 . African penguins live on the rocky coasts of South Africa, Namibia and nearby islands. Like other types of penguins, the birds have white feathers covering their chests and black feathers covering their backs. They form lifelong pair bonds with mates, but they nest in huge colonies — so, scientists wondered how the birds were able to identify their partners among the sea of black-and-white birds. They wondered if their chest spots had something to do with it. To test this theory, they studied 12 African penguins at a zoo and marine park near Rome called Zoomarine Italia.

In one test, they hung two life-size photographs of the African penguins. One showed a random member of the colony, while the other showed the test subject’s mate. The scientists recorded the birds’ interactions with the photos: How long did they spend looking at each one, as well as how much time did they spend standing near each photograph? The penguins spent more time gazing at the photo of their partners — about 23 seconds longer, on average — than looking at the other photo. They also stood next to the image of their beau s for twice as long. Then, the researchers covered up the heads of the birds in the photographs, leaving only their speckled bodies visible, and the penguins still lingered near their partners’ portraits.

In another experiment, the researchers hung up two photos of a bird’s mate — but, in one, they had digitally removed its spots. In this case, the penguin again spent more time looking at the photo with the dots.

Finally, the researchers posted two photographs of penguins with digitally removed spots — one of the test subject’s mate and the other of a random penguin from the colony. In this scenario, the penguins did not appear to recognize their partners. They spent roughly the same amount of time gazing at or standing near both photos.

Together, the results of these experiments suggest African penguins are zeroing in on their partners’ spots and using them like name tags, scientists say.

“Our results provide the first evidence of a specific visual cue responsible for spontaneous individual recognition by a bird and highlight the importance of considering all sensory modalities in the study of animal communication,” the researchers write in the paper.

The first “forest library” in Shanghai recently opened to the public, giving readers the chance     1     (relax) and read in a natural environment.

Known as Read & Joy Forest, the forest library that was     2     (joint) launched by Pudong New Area and Shanghai Library     3     (locate) in an urban green space area near Shanghai Library East. Covering an area of 20,546 square meters, it allows visitors to take a pleasant walk in the quiet and green forest,     4     includes many different kinds of trees.

The design of the forest library ensures minimal (极少的) disturbance to the forest, with existing green spaces     5     (connect) by wooden walkways. The library is in the open air and equipped with facilities such as benches and     6     information desk.

    7     (have) a library in the woods is an extension of reading indoors, according to Xu Qiang, one leader of Shanghai Library. “It offers different reading experiences to readers,” Xu added.

Most of the visitors to the forest library were young people and parents with their children, who either immersed (沉浸在) themselves in reading     8     took wanders leisurely in the forest. “The fresh air and the scents of the trees here are really     9     (impress). I’ve spent the whole morning indoors, and wanted to get some fresh air. The library makes it possible to enjoy reading in natural surroundings. I must say I have a     10     (prefer) for it,” said one reader sitting on a bench.
