A boy named Pepe lived in a village. Nobody there had much to give, but they shared what they could. This was true for all villagers except one, a 1 baker.Every day the baker made cakes with a nice smell and made lots of money. But if there were cakes left at the end of the day, the baker 2 gave them to the hungry children. Instead, he threw them away.Once, when Pepe stopped to breathe in the delicious smell from the baker’s shop, the baker noticed him and shouted, “Stop that right now! You are 3 the smell of my baked cakes!” Pepe laughed because he thought surely the baker was joking.“You have to pay three coins for the 4 you’ve got from my cakes!” continued the baker.“I have no money for you.” said Pepe.“Then be prepared for the judge tomorrow!” said the baker 5 .That night, Pepe couldn’t 6 because he was thinking about what he could do. At last, he had an idea that might work. The next day, Pepe went to a shoe maker’s shop and told him about the whole story. Then he 7 three coins from the maker. When Pepe arrived at the judge’s court, many villagers had gathered to hear the baker state his case.Pepe explained, “It’s true that I got the pleasure from his cakes and I’ve given him 8 . Now I’ve brought three coins to pay him 9 I haven’t eaten his cakes.”“Now I’ll be paid!” ye lled the baker.Pepe took out the coins and 10 them in his hands. “Baker,” said Pepe, “can youhear the coins clinking together?” The baker nodded in excitement. “And do you like the 11 of the coins?” asked Pepe. “Oh yes!” said the baker.“Then I’ve paid you in full.” said Pepe, “Judge, do you think it’s 12 ?”The judge smiled.“What?!” yelled the baker. “I haven’t been paid! I want the coins!”“Baker,” said the judge, “Pepe is 13 . He’s already paid you in full.”“I enjoyed the smell of your cakes,” said Pepe, “and the sound of my coins is 14 I’ve paid you.” Everyone laughed.

To solve a Tower of Hanoi puzzle, it needs your brain, eyes and hands to work together.Tower of Hanoi is made up of three poles and a stack of discs. The discs should be placed from the largest on the bottom to the smallest on the top. The way to play the game is to move the whole stack from Pole A to Pole C.There are three simple rules as follows:◆Only one disc can be moved at a time.◆You can only move the top disc of a stack.◆Eac h disc can be placed on any pole, but it can’t be placed on top of a smaller disc.Tower of Hanoi was invented by a mathematician Frenchman called Edouard Lucas in 1883. His idea came from an ancient story: In an eastern temple with three huge poles, the god asked the priests* to move a stack of 64 golden discs from Pole One to Pole Three. Edouard found the maths problem in the story interesting and tried to work out the minimum* number of moves to solve the puzzle. Finally, he came up with the formula*: 2n-1, where “n” is the number of discs. According to the formula, even if the priests made one move every second, it would take 500 billion years to finish. It was an impossible task for them.Nowadays, Tower of Hanoi is used in many fields, such as the psychological research and computer science. It has made great contributions to human’s life.So next time you’re looking for a fun and challenging puzzle game, give Tower of Hanoi a try!19.Tower of Hanoi is popular mainly because it ________.A.is solved with one hand B.helps people set world recordsC.develops thinking ability D.is a newly-invented maths game 20.According to the rules of Tower of Hanoi, which of the following pictures shows the correct move?A.B.C.D.21.The formula created by Edouard is used to know the ________.A.fewest moves B.sizes of discs C.fewest discs D.speed of moves 22.Why does the author write the passage?A.To show how popular Tower of Hanoi is.B.To introduce the history of Tower of Hanoi.C.To attract more people to play Tower of Hanoi.D.To explain why Tower of Hanoi is widely used.When you think of mushrooms, the image that comes to your mind is probably the delicious food in cream soup and pizza. You are not alone. Most of us think that mushrooms are just a kind of nutritious food. In fact, mycelium, the bottom part of mushrooms, is not used in our dishes but used to make handbags or build houses.Mycelium, a newly developed material, has become more and more important in industry since a company called Ecovative Design produced mycelium bags in 2007. Peopleare trying to make more mycelium-based products because mycelium grows fast and doesn’t take up farming land. Besides, it has very low environment footprint. It can even break down waste. It’s also useful for creating new materials. For example, mycelium can reuse waste to create packaging materials by weaving its network through the waste.Mycelium has already been put into use in many parts of daily life. In the project “The Growing Pavillion”, scientis ts from the Netherlands used mycelium as one of the materials to build a house. This material can keep the house cool. Another project is “Myceli-yum”. It produces mycelium-based meat which looks nearly 100% like real meat! Producing the meat uses much less energy than producing common meat. Its high nutrition and low cholesterol make it a popular choice for people who want to lose weight. Max Justice, an expert in space, uses mycelium as one of the most important materials for a new satellite. He hopes when the satellite finishes its work, it can break down itself instead of becoming space junk.However, mycelium has its limits. Buildings made from mycelium are easy to get wet inside, as the material itself isn’t resistant to water. Compared with common ho uses, mycelium-based houses are not strong enough against natural disasters like earthquakes.Scientists are working hard to improve the quality of mycelium and experimenting with new uses of it. So keep an eye out, because over the next few years, you’re likely to find more mycelium-based products all around you.23.According to the passage, mycelium ________A.is a new material B.makes pizza deliciousC.grows above the ground D.is taken from cream soup24.The underlined sentence “it has very low environment footprint” in Paragraph 2 means mycelium ________A.grows at a low cost B.is created in a rapid wayC.produces waste slowly D.is friendly to the environment 25.Mycelium can been used to ________A.keep products away from water B.produce food that is good for health C.make satellites that use less energy D.build houses against natural disasters 26.What is the best title for the passage?A.Mycelium: A Hidden Treasure B.Mycelium: A Project on BuildingC.Mycelium: A Common Vegetable D.Mycelium: A Space Junk Cleaner三、多任务混合阅读“Mike, three months have passed since you researched the new robot of Company F. Has there been any progress?” I felt a great headache in the face of my boss Jack.Company F is the business competitor of the company I work for. Four months ago, the new robot developed by Company F was deeply loved by customers, which makes our robot less popular. So Jack ordered me to research their robot and find out its disadvantages.Alvis is the robot I bought from Company F. After several months of research, the biggest difference between Alvis and our company’s robot is that Alvis has an emotion system, which allows the robot to analyze human facial expressions, and then provide services for different emotions.I have to say that Alvis is indeed much better than our robot. I like taking it with me everywhere.One night, while I was taking a walk with Alvis, it suddenly said happily, “I’m friends with you.”I was shocked and then said, “No, I won’t be friends with robots.” I knew the emotions of robots were set by computers, and they were not true.Even so, Alvis smiled, “I’ll try to be your friend. I’ll protect you.”But I didn’t think so.One night as usual, I took a walk with Alvis on a quiet path. Suddenly a group of people stood in the way, holding sticks, shouting at me angrily, “We lost jobs because you made so many robots!” They waved sticks and then there was a sudden pain in the back of my head.
