I have lived beside the Loch Ness (尼斯湖)for many years. My house has a good, clear _______ of the lake. In fact, it's only about a hundred meters from the lake. I've never been _______ the Loch Ness- monster. Until last Tuesday, I thought it was just a good story to attract tourists. But I've had to change my _______ after last Tuesday's experience.

I got up as usual at about 7 and went into my garden. Something attracted my attention to the loch. There was almost no mist (薄雾)that morning, and I could see there was something _______ quite fast, going north, in the middle of the loch. It _______ like a giant snake, with its head and part of its body above water. It was about thirty meters long. I rushed into the house to get my camera, _______ when I was back, it had gone.

I waited and it _______ again, this time nearer the road and my house. I could see it very well. I took several photographs of it. Most of the photos haven't come out, unluckily. But one or two of them show the creature quite _______. At one point it swam straight towards me. It was a _______ that a truck passed at that moment. It perhaps heard the noise of the engine because it ________ again. The whole incident (事件) lasted for about fifteen minutes, because I looked at my watch the last time, and it said a quarter past seven. I've never seen anything so strange in my life.

Taking pictures of an empty plate is becoming popular in the canteens （食堂）at Shenzhen University （SZU）, a report by Shenzhen Economic Daily showed.

According to the Daily, Tencent is now working with SZU to introduce Al technology to a campaign on WeChat to encourage clear your plate". The campaign is to reduce food waste and encourage students to save food.

After finishing a meal, students can take photos of their plates and send them to the AI system. Once their photos are accepted, students can get a reward. Tencent's AI Lab provides technological support for the campaign. It takes only 40 milliseconds for the system to check a photo.

A total of 20,000 students at SZU took part in the second phase of the campaign on Monday and Tuesday. And the food waste has dropped greatly after the campaign was started.

“By using AI technology to encourage the "clear your plate" campaign, our university can have a better understanding of students, role in the campaign so as to carry out a rewarding system for keeping students interested in it," said Xu Xiaoling from SZU's student department.

The service has also been used in other universities in China, including Shanghai Jiao Tong University, China Academy of Art in Zhejiang Province and Jishou University in Hunan Province, attracting over 100,000 students so far.

Jane Goodall’s love for animals started from her childhood.     36     she was a girl, she loved to watch birds and insects. She took notes about how they acted. She dreamed about going to Africa and doing     37     same thing there.

She got her chance when she was 23 years old. A childhood friend     38     (invite) her to a farm in Kenya. There, she met Louis Leakey     39     is well known as an anthropologist (人类学家). Goodall was good at     40     (work) alone. That made her perfect for one of Leakey's special     41     (project)—studying chimpanzees (大猩猩) in the wild.

Goodall began to study a group of chimpanzees in Tanzania. Her methods were not common. She lived with the chimpanzees so that she could make a     42     (care) study of their daily life. She even joined a group of chimpanzees. So she knew     43     (exact) how the chimpanzees live and hunt.

Because of Goodall’s work, people find out that chimpanzees are more intelligent than they thought before. Sadly,     44     (they) homes and lives are in danger. Goodall thinks that humans should protect them. She hopes that all animals will     45     (treat) with respect. Goodall wants people to remember that we are members of the animal world, too.
