Now Shimon doesn't simply play music, he also writes the words to his own songs and sings them. Shimon has been around for quite a while as a musical robot. Even back in 2015, he was playing with other musicians at the Kennedy Center in New York. What Shimon could do back then was already pretty cool. Using AI（人工智能）, Shimon was taught to write his own music. ① For Shimon, that meant he could not only make up his own music, but do it in real time, while playing with other musicians. Now Shimon can write the words to his own songs. _②_ Shimon learned to write the words for the songs the same way he learned to write music—by being "fed" thousands and thousands of examples. Shimon was trained on the lyrics （歌词） to 50, 000 songs. Georgia Tech professor Gil Weinberg, who leads the Shimon project, gets Shimon going with a starting idea. Shimon then writes the lyrics based around that idea. "You'll get a word like 'storm', and then it'll produce a lot of relational words, like 'wind' and 'rain'. "He says Shimon gets many ideas, keeps the good ones, and builds on them. ③ To give Shimon a voice, the Georgia Tech team worked with experts at Pompeo Fabre University in Spain. The voice was created using AI and sounds very much like a man. ④ To show off Shimon and his new abilities, the researchers have recorded one of Shimon's songs, called "Into Your Mind". They have made a video for the song, which is out on YouTube. Later this spring, the team plans to put out an album（专辑） of about 8-10 of Shimon's songs. There are also plans for Shimon to go on tour with a band to play and sing his songs live. For Mr. Weinberg, that's the main goal behind the Shimon project—-not to have robots take over, but to have robots and humans make something beautiful together. 1. The aim of the first paragraph is _______________. A. to give an introduction B. to lead a music topic C. to explain a science problem D. to make a conclusion 2. Paragraphs 3-5 mainly talks about _________________. A. the number of the songs he writes B. the process to write Shimon’s own songs C. the history of Shimon's development D. the reasons for developing a musical robot 3. Where can the sentence "Singing songs is another story" be best put? A. ①. B. ②. C. ③. D. ④. 4. Which of the following is NOT true according to the passage? A. Shimon was produced before 2015. B. Shimon writes songs beginning with his own ideas. C. Researchers are expecting more things from Shimon. D. "Into Your Mind" is a song written by Shimon with the AI voice. Keys:ABCB 简答题 The United Nations announced on April 19 that India is going to become the most populous（人口稠密的） country in the world by the end of June. In 2022, India had more than 1. 412 billion people, which was very close to China's population of 1. 426 billion people. India's population is expected to grow to almost 1. 43 billion by the middle of the year, surpassing China's. One of the main reasons for this rapid growth is that many babies are born in India every year, more than in any other country, Time magazine noted. Having a big population can be good for the economy（经济） because more people can work and earn （赚钱） money, which can lead to economic growth, the Associated Press noted. More companies from other countries and regions may come to India because of this. However, having a big population can also be challenging because there might not be enough resources（资源） like food, healthcare and education for everyone. CNN stated that it could also be hard for people to find jobs because so many people are looking for work. According to a 2021 report from the World Bank, India's labor force participation rate（劳动力参与率）, which is the proportion（比例） of the active labor force in the working-age population, is 46 percent-the lowest in Asia. Despite these challenges, India is still a country with many opportunities for growth. Many companies are choosing to set up factories in India to make things like mobile phones and semiconductors（半导体）. Morgan Stanley, the investment bank, said that India will have unprecedented（前所未有的） economic growth and become the world's third-biggest economy by 2027. 1. How big will the India's population be by the middle of this year? ________________________________________________________ 2. Why is India's population increasing quickly? ________________________________________________________ 3. What is the labor force participation rate? ________________________________________________________ 4. What is Morgan Stanley's prediction about India's future economy? ________________________________________________________ 5. What do you think of the large population in India? ________________________________________________________ Keys: 1. Almost 1.43 billion. 2. Because many babies are born in India every year. 3. It’s the proportion of the active labor force in the working-age population. 4. India will have unprecedented economic growth and become the world’s third-biggest economy by 2027. 5. It’s good for the economy./It may be a big problem in the future. 缺词填空 Anjiazhuang used to be a quiet village. But now, it has turned into a m 1 town. This is all because of the railway station.

Most of the students thought the girl’s behavior was 1 . Ms. Whitehead didn’t 2 her opinion, instead, she told another story. “It was about a loving couple who were travelling on a ship. Unfortunately, they met with a storm and the ship was going to sink (沉没), only 3 of the couple could have the chance to the lifeboat. 4 all passengers’ surprise, the husband left his wife behind and got on the lifeboat himself.” The teacher stopped and asked, “How would you feel if you were one of the passengers?” Shortly after, continued Ms. Whitchead. “The husband survived home. He didn’t marry others but 5 their daughter alone after the worst day. 30 years 6 , the daughter learned about what happened on the ship by accident. Although she really wanted an 7 from father, her love for her father was always in the way. Her question in her heart wasn’t answered until she happened to find out it in his diary after her father died. The whole 8 is, on that day, her father and mother were on the trip to finish her 9 wish because she was dying of an incurable (不治的) illness. As a husband, he 10 to go with his wife.

Yes, the great husband is my father.” The class dropped into 13 as Ms. Whitchead finished her story.

Somebody asks you to go for a party but you have tests the next day, or to help them although you are busy at the moment, or to join the activities you have no interest at all! Even though your heart is crying NO, you find the word “Yes” come out of your mouth. However, it usually results in anger — not only for the person who asked you, but also for yourself for not being strong enough. ②Lisa Messenger, the Collective Hub CEO, said in her first few years of business, many people asked her to talk over a coffee. Actually, she usually ended up having 20 coffee meetings a week and that stopped her from doing business because she didn’t have time to do her own work. ③Messenger finally learned to refuse like “No, I’m sorry, but I don’t have time.”. She believes if you say “Yes”, you will regret later. Or your heart will be filled with guilt, fear or anger because you feel bad for agreeing to do something you never want to. So you need to be brave enough to say “No” when you’re asked at first. ④Janine Garner, CEO of The LBD Group, believed we need to get very clear about our goals. Unless we work towards our goals, nobody else will care about our time. Garner said, “We may end up saying ‘Yes’ because we feel sorry for somebody who needs us. But we end up having that awful feeling in our heart. You can only achieve the best of you by stopping doing the things that take up your time and don’t add anything towards your goals. Take a good look at the time spent on others, which you really should spend on yourself.” 1．How does the writer begin the text? A．By telling a story. B．By giving examples. C．By making a survey. D．By asking questions. 2．What does the underlined word “that” in Paragraph 2 refer to? A．Having 20 coffee meetings a week. B．Being asked to buy coffee 20 times. C．Talking with others without coffee. D．Drinking 20 cups of coffee a week. 3．Which opinion would Janine Garner probably agree with? A．Offering help is the key to make friends. B．Helping others may make you successful. C．You’d better say “No” bravely if necessary. D．People who need us will care about our time. 4．What’s the structure of the passage? A． B． C． D． Keys: BACC 六选五 Question: In ancient China, willow branches (柳树枝) were often used as a parting gift between friends and family members. 1 Answer: One reason is that willow trees are strong. 2 Because of this unique (独特的) feature, giving a willow branch to say goodbye to loved ones is a way to tell them you hope they will easily adapt to their new living environment. Meanwhile, in Mandarin, the pronunciation for the willow tree “liu (柳)” is similar to the character “liu (留)”, which means asking someone to stay — only the tones (声调) are different. 3 Even though we know that they must leave, we still do like that. 4 At that time, Baqiao, a bridge in Chang’an, today’s Xi’an, was a common place to say goodbye. People often stopped there and handed willow branches to departing (离开的) people. 5 In The Book of Poetry, there is the line “When I left there, willows shed tears.” At the time of the Tang and Song dynasties, such poems were common as traveling was easy and poets felt the sorrow of separation. For example, Wang Wei wrote “The willows by the hotel look so fresh and green,” in his famous poem A Fond Farewell to a Friend. A．They can survive in any soil, wet or dry, north or south. B．When the willow leaves become dark green, spring is gone. C．It’s said that this custom became popular during the Han Dynasty. D．Do you know why willow branches are a symbol of farewell (告别)? E．So offering a willow branch is like asking the other party (对方) to stay. F．Willow branches, as a symbol of farewell, are often mentioned in poems.
