1 . Recently, Google researchers published a paper describing results from an artificial intelligence(AI) tool, called MusicLM, built to create music. It is not the first AI music tool to launch. But the examples Google provides demonstrate musical creative ability based on a limited set of descriptive words. AI shows how complex computer systems have been trained to behave in human-like ways. Google engineers explain the MusicLM system this way.
First, a user comes up with a word or words that describe the kind of music they want the tool to create. For example, a user could enter this short phrase into the system: “a continuous calming violin backed by a soft guitar sound.”The descriptions entered can include different music styles, instruments or other existing sounds. Several different music examples produced by MusicLM were published online. Some of the generated music came from just one-or-two-word descriptions,such as “jazz”, or “techno”. The system created other examples from more detailed descriptions containing whole sentences. In the resulting recording, the music seems to keep very close to the description. The team said that the more detailed the description is, the better the system can attempt to produce it.
In addition to generating new music from written descriptions, the team said the system can also create examples based on a person’s own singing, whistling or playing an instrument. The researchers said the tool “produces high-quality music...over several minutes, while being faithful to the text conditioning signal”.
Although MusicLM hasn’t been released for public use, Google announced it was releasing a “high-quality dataset” of more than 5,500 music-writing pairs prepared by professional musicians called MusicCaps. The researchers took that step to assist in the development of other AI music generators.
The MusicLM researchers said they believe they have designed a new tool to help anyone quickly and easily create high-quality music selections. However, the team said it also recognizes some risks linked to the machine learning process.

Mary waited anxiously for her turn in the empty dressing room. Never had she been so nervous before. This competition was of great importance to her comeback. “If I can win today,” she said to herself, “I can dance on the national stage next month.” Three months ago, her left arm was seriously injured in a car accident. After the medical treatment, she began to recover slowly. She practiced over and over again in order to regain her dancing skills.
“Hi, Mary,” in rushed her friend Jessica. “How is your arm? Is it going to influence your performance?”
“I guess it can be tolerated for I am to win the match.” said Mary with a determined look.
“Admirable! But I hear that a girl called Linda is really gifted and strong. She can be your real well-matched competitor. Come on!”
After Jessica left, Mary decided to practice her most difficult spin (旋转). “If I don’t try harder, I won’t grasp this chance.” She thought. But her arm began to hurt, making her worried. “Mary, what makes you think you have a chance tonight?” she said to herself. After the pain was gone, she continued to warm up.
A slim girl hurried in and put down an equipment bag on the chair. Then, she took out her dance dress quickly and put it on skillfully. Seeing Mary, she smiled politely and said “Hi, I’m Linda. I am the next one to you!” Mary nodded in reply but felt uncomfortable. “This is just my competitor. Because of her, I may lose tonight.” Her mind was wandering when Linda let out a scream, “Oh, God, I can’t find my music tape!” Linda searched her bag but in vain (徒劳). “It may be missing on the way.” With these words, she then rushed out.

Suddenly, Mary caught sight of a black box under the chair where Linda put her bag.

My great-grandfather, my grandfather and my father are farmers, and so are all my family. My father has a fixed idea that I would become a farmer too. Although I respect him and am indeed skilled at doing some farm work, I don’t agree that I should automatically follow in my father’s footsteps.
When I was a teenager, my father happened to take me to an airport which belonged to one of his friends. It was the first time I had seen an aeroplane in real life. Knowing that I had never been on board, my father’s friend Tom offered me an opportunity to fly with him in his small aeroplane. I quickly accepted his offer! When we took off, I felt nervous but thrilled. Being up in the clouds and looking at the view below was unlike anything I had ever felt. I was just enjoying it. I assumed being a pilot would be the most awesome thing in the whole world. From that day a thought crept into my mind that I wanted to become a pilot, but I doubted whether my father would support me. After all, it was a totally different path from what he had planned for me. Therefore, I put the thought to the back of my mind, because I knew he would still insist on holding onto his previous idea.
Anyway, besides helping my father on the farm, I would frequently visit Tom’s airport. Gradually, I got familiar with every button and switch on the aircraft and I learned a lot about planes, such as how to fill the plane with fuel, how to check the engines and so on. But what I had learned just left me wanting more, so I decided to go to college to become a professional pilot.
Paragraph 1:This time I would not hide my desire any more.

At the graduation ceremony, with my father present, I, as “Best Pilot”, had to deliver a speech.

Blue light before bedtime can make it harder to sleep, and the screens on phones, computers, and televisions send out plenty of blue light. This is all true. But if you’re focused on blue light as a major problem affecting your sleep or your eye health, it’s time to look at it from another aspect.
As Philip Yuhas, a professor of vision, writes at The Conversation, blue light isn’t a uniquely technological evil. It’s part of sunlight, and your eyes are exposed to plenty of it all the time. You ‘ re fine. There are studies in mice that have found blue light can damage their eyes, but mice are nocturnal creatures (夜行动物) whose eyes are different from ours. The pigments (色素) and the lenses (晶状体) of our eyes actually block blue light fairly well-so in a sense, we already have built-in blue blocking protection
Adding more protection isn’t likely to help though. You can buy glasses and screen filters (滤光片) that block blue light, but Yuhas points out they are probably a waste of money: these products do not block out much blue light. The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens send out. You could get the same reduction just by holding your phone another inch from your face.
The American Academy of Ophthalmology doesn’t recommend blue-blocking products, either. Instead, if you’re concerned about your eye health or your ability to get to sleep on time, you already know what to do:
Put the screens away at bedtime. Read a book or find something else to do. While you’re using screens take a 20-second break every 20 minutes to look at something 20 feet away ( the “20-20-20 ” rule ). If you get dry eyes when you look at screens for a long time, use eyedrops labeled artificial tears.

6 . It was summer, and my dad wanted to treat me to a vacation like never before. He decided to take me on a trip to the Wild West.
We took a plane to Albuquerque, a big city in the state of New Mexico. We reached Albuquerque in the late afternoon. Uncle Paul, my dad’s friend, picked us up from the airport and drove us up to his farm in Pecos.
His wife Tina cooked us a delicious dinner and we got to know his sons Ryan and Kyle. My dad and I spent the night in the guestroom of the farm house listening to the frogs and water rolling down the river nearby. Very early in the morning, Uncle Paul woke us up to have breakfast. "The day starts at dawn on my farm," he said. After breakfast, I went to help Aunt Tina feed the chickens, while my dad went with Uncle Paul to take the sheep out to graze(吃草). I was impressed to see my dad and Uncle Paul riding horses. They looked really cool.
In the afternoon, I asked Uncle Paul if I could take a horse ride, and he said yes, as long as my dad went with me. I wasn’t going to take a horse ride by myself anyway. So, my dad and I put on our new cowboy hats, got on our horses, and headed slowly towards the mountains. "Don’t be late for supper," Uncle Paul cried, "and keep to the track so that you don’t get lost!" "OK! " my dad cried back. After a while Uncle Paul and his farm house were out of sight. It was so peaceful and quiet and the colors of the brown rocks, the deep green pine trees, and the late afternoon sun mixed to create a magic scene. It looked like a beautiful woven(编织的) blanket spread out upon the ground just for us.
Suddenly a little rabbit jumped out in front of my horse.
