The Amazing Penguin Rescue

    The summer of 2016, the ship MV Treasure sunk, creating an oil spill. Thirteen hundred tons of fuel oil were flowing right in the middle of the African Penguins' habitat. Soon the oil covered about 20,000 penguins. Without swift help, the seabirds would have no chance for survival. Volunteers were showing up by the thousands and I also took part in what was the largest animal rescue operation ever.

    A warehouse was turned into a rescue center near the habitat and hundreds of pools were built to hold about 100 oiled birds each. When walking into the center, I couldn't believe my ears. I had expected to walk into a chorus of honking and squawking(叫声). Instead, the center sounded like a library. The penguins were dead silent. My heart ached for the painful birds. Cleaning them all seemed like an impossible task. But we had to carry on like doctors in an emergency room. There was no time for doubt. Cleaning oil off a penguin wasn't easy. Even with more than 12,500 volunteers, it took a month to bathe all 20,000 birds at the center.

    While volunteers were busy bathing the oiled penguins, another crisis (危机) was developing. Oil from the spill had started moving north. Tens of thousands of penguins were in the oil's path. But we already had our hands full with 20,000 recovering birds. If any more birds were oiled, we wouldn't have enough resources to save them.

    One researcher came up with an idea: What if the penguins were temporarily moved out of harm's way? Experts decided to have a try. Volunteers rounded up the penguins and released them 500 miles away. The hope was that by the time the seabirds swam home, the oil would be gone. The plan worked! Another 20,000 penguins were saved.

    The entire penguin rescue took about three months. More than 90% of the oiled penguins were successfully returned to the wild. Looking back on the rescue, I am still amazed by the work of the volunteers. What I could hardly believe was that we accomplished an impossible task.

    For more than fifty years, a worker was forced to sit on the back of a truck and slowly drop plastic barriers（障碍） to set out lanes（车道）on the Golden Gate Bridge in San Francisco. Every day, their direction changes to control the traffic, meaning an employee had to go through the difficult task every twenty-four hours.

    But a new piece of machinery means the work can be completed in a matter of minutes. A new “zipper truck” has been introduced. The vehicle lays and moves a lane barrier as it drives over the bridge. Last weekend, the bridge was closed so the new safety barrier, designed to reduce the dangers of head-on crashes, could be set up.

    For the longest period in its nearly eighty-year history, the bridge was closed early Saturday to all but walkers, cyclists and buses to set up the barriers on the 1.7-mile bridge. A survivor of a 2008 head-on crash on the bridge spoke Sunday from a wheelchair to help introduce the new barrier, made of steel-clad concrete（铜包混凝土）blocks that can move across the bridge's six lanes to meet traffic needs.

    Gr. Grace Dammann pushed for a safer barrier since becoming unable to walk after the accident. She said she decided to drive near the middle of the bridge, which was called the “suicide（自杀）lane”, because she and her daughter were running late. Brian Clark, who was driving in the opposite direction, had just learned his father had cancer. “He suddenly lost control of the wheel, crossed over and hit my car,” Dammann said.

    She said she and Clark became friends as they persuaded（说服）the government to use the MYM30 million barrier. “I am so thankful,” said Dammann, who came to the ceremony with Clark.

    “Clark and I thank you.”

    If you have the opportunity to visit some places in New Zealand, then the list below is our recommendation.

    Fiordland National Park

    This park is part of the South Westland World Heritage Area and is New Zealand's largest national park and one of the largest in the world. The scenery in Fiordland is nothing short of extremely beautiful, with steep mountains, wild waterfalls, and abundant rain forests. Being able to come back and forth in its deep bay attracts most of the visitors.

    The area has some of the world's greatest walks including the world famous Milford Track, which was described as the finest walk in the world in the early twentieth century.

    Abel Tasman National Park

    Abel Tasman may be New Zealand's smallest national park, but the attractions are huge. Located in one of New Zealand's sunniest spots, the area also has the best beaches in the country.

    The popular Abel Tasman Walk is a great way to see this park. It takes 3-5 days to complete. Sea taxis are also available and can drop you off at any number of beaches within the park.

    Rotorua

    Accessible from New Zealand's biggest city, Auckland, Rotorua is famous for its volcanic activities. Rotorua is also famous for its plentiful lakes which are great for swimming and fishing. The surrounding area contains plenty of native bushes and some famous walks.

    Rotorua is also the best area in the country to experience and learn about Maori culture.

    Mt Cook National Park

    Mt Cook as well as the surrounding area is an alpine(高山的) park within the World Heritage listed in South Westland. The biggest peaks in all of Australasia are here. The park doesn't contain many trees or plants due to the altitude. Walks range from a two­hour walk to difficult tracks suitable for experienced mountaineers only.

    A helicopter or plane ride gives visitors excellent views of the mountains with the option of landing at the top of Tasman Glacier, a true permanent snow­covered alpine environment.

    Last week I was riding my special motorbike and then stopped at a convenience store. As I was getting my wheelchair off the back, a man watched me from his car and I noticed a wheelchair in his back seat. We spoke for a moment and I asked him about the wheelchair. He answered that it was for his daughter. "Well, do you think she would like to go for a ride on my motorbike with me?" I asked. He seemed shocked that a total stranger would ask him this. He thought about it for a second and said, "OK, as long as I can follow you."

    He introduced me to Amy and he sat her on my back seat. Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas. As we came back to the convenience store, she said, "This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn't know I could do this." I told her about some of the other things I do (ski, travel the world by myself, etc.). As her father was taking her off my bike, she turned to him and said, "Oh Daddy, I'm going to be OK. Mr. Bryant does all kinds of things, and I will too." Her father turned away as a tear of joy rolled down his cheek. He hugged me and said, "I was sitting here praying for a gift for Amy that would encourage her. She often felt that her life was dull compared to other children. God answered my prayer just now. Now I pray that God will bless you for your gift to Amy today." I believed what he said. Being kind and thoughtful to others, we can be an answer to prayer.

Livestreaming (直播) through platforms such as Amazon Live and TikTok is an increasingly popular way to sell goods online. It usually lasts between 5 and 10 minutes, and someone promotes a product. Viewers can then readily buy it by just clicking on a link.

We analyzed (分析) 99, 451 sales cases on a livestream selling platform and matched them with actual sales cases. In terms of time, that is equal to over 2 million 30-second television advertisements.

To determine the emotional (情绪的) expression of the salesperson (销售员), we used two deep learning models: a face model and an emotion model. The face model discovers the presence or absence of a face in a frame of a video stream. The emotion model then determines the probability that a face is exhibiting any of the six basic human emotions: happiness, sadness, surprise, anger, fear or disgust. For example, smiling signals a high probability of happiness, while an off-putting expression usually points toward anger.

We wanted to see the effect of emotions expressed at different times in the sales cases so we counted probabilities for each emotion for all 62 million frames in our database. We then combined these probabilities with other possible aspects (方面) that might drive sales — such as price and product characteristics — to judge the effect of emotion.

We found that, perhaps unsurprisingly, when salespeople show more negative emotions — such as anger and disgust — the volume of sales went down. But we also found that a similar thing happened when the salespeople show high levels of positive emotions, such as happiness or surprise.

A likely explanation, based on our research, is that smiling can be disgusting because it lacks true feelings and can reduce trust in the seller. A seller's happiness may be taken as a sign that the seller is gaining interests at the customer's expense.
