The program is intended to make and promote positive changes in the world. As Dr. Goodall says, “What you do makes a difference, and you have to decide what kind of difference you want to make.”In Bulgaria, where I live, homeless dogs are everywhere. Many people here turn a blind eye to them. But I cannot ignore the life of a street dog whenever I see one wandering in the street, looking for something to eat. That’s why I’m no longer a food waster. When I see wasted food, I always think of a hungry dog climbing to garbage bins, searching for food that people have thrown there. When eating in a restaurant, I’m not afraid to take leftover food to feed stray cats or dogs.A week ago, I saw a homeless dog around the garbage bins. Immediately I knelt down, spoke to her softly and ran my hands over her. I could see that she had had puppies. I couldn’t imagine how she could have been able to care for them. Hours earlier, I’d bagged up a plate of leftover fish. As I unwrapped it, she wagged her tail and sniffed at it. She ate all the fish in no time.It’s sad, isn’t it? I can’t understand why many of us waste so much and think little of it. These homeless animals have taught me that food is precious. Even when I don’t have leftovers with me, I’ll take the time to get something from the grocery store to feed them.I know my power is small, so I hope that next time you see wasted food, do turn it into worthy food. You have the power to save a life!25. The author uses what Dr. Goodall says to show__________.A. how we can develop our businessB. why it is important to be greatC. why the program is popular globallyD. how we can change the world positively26. What can be concluded from the text?A. There are few homeless dogs where the author livesB. The author takes homeless dogs home and raises themC. Seeing homeless dogs makes the author never waste foodD. People throw food into garbage bins to feed homeless dogs27. The author took the leftover fish with him to____________.A. eat it when he was hungryB. feed a homeless dog he metC. look for more homeless animalsD. set an example to those who throw away food28. The author wrote the text to ask us to__________.A. value our foodB. treat dogs as our friendsC. save wasted food for homeless dogsD. raise homeless dogs and catsCOff the coast of Hawaii’s Big Island swim masses of colorful tropical fish. Some of these fish will be caught and sold, ending up in aquariums around the world. Is the industry putting populationsof the fish at risk?Scientists who have studied the Big Island fishery say it is well managed. Rules put in place more than 15 years ago have helped to protect the fish. Along 35% of the coastline, for example, fish collecting is banned. Two years ago, the state cut the number of fish species for the aquarium trade from hundreds to just 40.Conservationist Robert Wintner objects to the findings. Wintner, who owns snorkel shops across Hawaii, started the Snorkel Bob Foundation to protect the island’s coral reefs(珊瑚礁). He says he simply doesn’t see yellow tang(刺尾鱼)in the protected areas. “There should be millions of them,” he says. “Where are tphey?”Wintner says people believe the numbers in reports. But few people have actually dived into the coral reefs to see for themselves how many fish can be found there. According to Wintner, the coral reefs along the coast should be filled with yellow tang, but they are “virtually empty”. Empty reefs are not good for tourism, Wintner points out, which brings out $800 million yearly. By contrast, the aquarium-fish trade brings out just $2 million yearly.29. According to Robert Wintner, ________.A. what the recent report says is wrongB. there are millions of yellow tang off Hawaii’s Big IslandC. the yellow tang’s population off Hawaii coast is largeD. the yellow tang is sold merely for both food and the aquarium industry30. Which of the following is caused by the empty reefs?A. Worse tourismB. More fish deathC. More hungry peopleD. Less swimming events31. What can be the best title for the text?A. Who will Win the Debate?B. Is the Tropical Fish Healthy?C. How Should We Protect Tropical Fish?D. Should the Sale of Tropical Fish be Banned?DComputers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.Why is poker(扑克)so difficult? Chess and Go are “information complete”games where all players can see all the relevant information. In poker, other player s’ cards are hidden, making it an “information incomplete” game. Players have to guess opponents’ hands from their actions----tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold’s Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”After two hours of quite defensive play, from the computer at least, we called it a draw.32. Why can’t the computer beat humans at the poker game?A. Because humans are cleverer than the computerB. Because humans practice playing the poker game every dayC. Because the computer can’t learn the regular rules of the poker gameD. Because the computer can’t know the other players’ cards completely33. What does the underlined word “vanquishes” in Paragraph 3 mean?A. LeavesB. DefeatsC. CheatsD. Serves34. What do we know about the reinforcement learning of AI?A. It solves problems correctly every timeB. It is the same as the learning of humansC. It learns from the mistakes appearing in a taskD. It is more developed than the studying ways of humans35. What can be inferred from the text?A. The new procedure of AI has some features of humansB. Computers are stronger than humans in every aspectC. Humans will beat computers at playing poker foreverD. Scientists feel unhappy about the result of the poker game第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
