Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.
Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, and the life of American people. Most of the radio programmes are music.
Pop or popular music singers make much money. They make a CD or tape which radio stations use in many places. Once the popular singer is heard all over the country, young people will buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.
There are other kinds of music that are important to Americans. One is called folk music. It tells stories about the common life of Americans. Another is called western or country music. This was started by cowboys who would sing at night to the cows they were watching. Today any music about country life and the love between a country boy and his girl is called western or country music.

【推荐1】The past year has been full of tragedies and tears, but we still have music—which can both reflect the times and lift us up when we're down. We picked three songs from Time magazine's Top 10 Best Songs of 2020.
People I've Been Sad
“If you fall apart, then I'm falling behind you/ You know the feeling/ You know the feeling.” These words were written by Heloise Letissier as she grieved the death of her mother. A lot of people resonated with (和...产生共鸣) the lyrics in this troubling year. “It's a principle of acceptance of common suffering and of making peace with tragedy — and her open voice makes it nearly impossible not to hum along.” Time wrote.
WAP
WAP is a hip-hop song by Cardi B and Megan Thee Stallion. It was Cardi B's fourth No.1 hit on Billboard's Hot 100 in the Us.
“As a track, WAP is simple yet effective: a juicy bassline (低音声线)... of Cardi and Megan trading verses (歌曲的段落), with barely a break to catch a breath. It is infectious.” Time wrote.
Think About Things
This Icelandic pop song became popular on social media after a special quarantine (隔离) dance challenge set to the song spread rapidly.
“The song showcases parental love with a modern twist,making the song instantly palatable and attractive regardless of the song's meaning.” Maggie McHale wrote on At Wood Magazine.

【推荐2】The conductor on the podium (指挥台) has no baton (指挥棒), no tailcoat and no musical score, but Android Alter 3 is kicking up a storm as it guides a symphony orchestra's players through their paces.
The robot has a humanoid face, hands and lower arms, which gesture with what could pass for passion as it bounces up and down and rotates during the live performance of Keiichiro Shibuya's opera Scary Beauty in the Emirate of Sharjah.
Video from the recent performance in the Emirate of Sharjah showed the machine turning to face orchestra members and waving its arms. Alter 3 even sang at times.
Shibuya said the involvement of robots in the everyday lives of humans is continually increasing. But, he said he thinks people will need to decide in the future how artificial intelligence can best improve the human experience.
Shibuya added that he believes humans and robots can learn to work together to create beautiful art. "This work is a metaphor of that relations between humans and technology," he said. Shibuya noted that sometimes the music-leading robot can "get crazy", making it difficult for the musicians to keep up. But other times, the humans and machines cooperate very well.
Shibuya said the robots and AI that exist today are "far from complete". He is interested in studying how such incomplete technology can be combined with art.
"I think this is a very exciting idea…We came to see what it looks like and how much is possible," said Anna Kovacevic. Another audience member, who gave his name only as Billum, said after the show, "You know, a human conductor is so much better." Although he said he is interested in AI and looks forward to big developments, he concluded on the project: "The human touch is lost."
1. What does Shibuya think of Alter 3?A.It is not perfect at present. | B.It teams up with humans well. |
C.It often makes humans crazy. | D.It is better than human conductors. |
A.The performance drew mixed reactions. |
B.Billum took no interest in the performance. |
C.The audience were fascinated by the performance. |

【推荐3】At first sight, Alma Deutscher, a sixteen-year-old girl from England appears to be like any other typical teenager. She loves to skip rope, read and play with her younger sister. But this modest youngster, who composed her first musical work at age six, first short opera at age seven, and first full-length opera based on Cinderella at age ten, is anything but average. Though her parents downplayed(淡化)her extraordinary talent, young Alma is being described as “little Mozart” by the music world.
Alma’s opera based on the classic fairy tale, which she began writing at age eight, has a slight twist. Her Cinderella is a musician who meets her Prince Charming, a poet through a song. “In my Cinderella, she sings the beginning of a ballad—but at midnight she flees. Eventually, the prince finds her after asking all the girls of the country to sing the end of the ballad.”
The opera was first performed in Vienna, Austria on December 29, 2016, where the then eleven-year-old skillfully switched between the piano and the violin and received enthusiastic reviews. The young genius has since performed two new piano works, one in Australia and the other in China.
While this may appear to be a lot for someone so young, Alma is not worried. She says, “Of course I have to work hard. But all children have to work hard for exams, and at least when I work hard, I work hard for something incredibly exciting, like seeing my whole opera put on.”
Alma’s musical talent first came to light before she could even talk. Her parents recall that as an 18-month-old toddler, she was able to hum a perfect version of the children’s rhyme Twinkle Twinkle Little Star.
However, Alma’s abilities only gained international attention in 2012, after a family friend posted a video online comparing her to Mozart. The family was suddenly swamped with media and Alma became an overnight star, dubbed “little Mozart”. This nickname makes her parents unhappy because they believe it puts added pressure on the young girl. They would instead prefer her to be called “a composer and musician”.
Alma does not want to be compared to the famous artist either, saying “There was only one Mozart, and I prefer to be little Alma.” Regardless of what she calls herself, the sixteen-year-old is changing the world of music forever!
1. Which of the following statement about Alma is WRONG?A.She can play the piano and the violin skillfully. |
B.She can write operas and compose music as well. |
C.Her talent goes far beyond that of Mozart. |
D.She displayed her talent for music at an early age. |
A.Disadvantage. | B.Change. | C.Improvement. | D.Error. |
A.Cinderella meets her Mr. Right through a song. |
B.It is a short opera based on the classic fairy tale. |
C.The prince finds her with the help of a crystal shoe. |
D.It enjoys a great success and has been performed in China. |
A.Overexcited. | B.Concerned. | C.Happy. | D.Shocked. |
【推荐1】It is not only praise or punishment that determines a child’s level of confidence. There are some other important ways we shape our kids — particularly by giving instructions and commands in a negative or positive choice of words. For example, we can say to a child “Don’t run into traffic!” or “Stay on the footpath close to me.” In using the latter, you will be helping your kids to think and act positively, and to feel competent in a wide range of situations, because they know what to do, and aren’t scaring themselves about what not to do.
Why does such a small thing make a difference? It is all in the way the human mind works. When we think, we automatically rehearse. For example, if someone offered you a million dollars not to think of a blue monkey for two minutes, you wouldn’t be able to do it. When a child is told “Don’t fall off the tree,” he will think of two things: “don’t” and “fall off the tree”. That is, he will automatically create the picture of falling off the tree in his mind. A child who is vividly imagining falling off the tree is much more likely to fall off. So it is far better to use “Hold on to the tree carefully.”
Clear, positive instructions help kids to understand the right way to do things. Kids do not always know how to be safe, or how to react to the warning of the danger in negative words. So parents should make their commands positive. “Sam, hold on firm to the side of the boat” is much more useful than “Don’t you dare to fall out of the boat?” or worse still “How do you think I’ll feel if you drown?” The changes are small but difference is obvious.
Children learn how to guide and organize themselves from the way we guide them with our words, so it pays to be positive.
1. Positive choice of words helps kids to____________.A.do things carefully | B.build up their confidence |
C.improve their imagination | D.learn in different situation |
A.A child will act on what is instructed. |
B.One can’t help imagining what is heard. |
C.A child will fall off the tree when told not to. |
D.One won’t think of a blue monkey when given money. |
A.Fasten your seat belt. |
B.Don’t play by the lake. |
C.How do you think I’ll feel if you get hurt? |
D.Don’t you dare to walk through the red light. |
A.praise makes kids confident |
B.right instructions keep kids safe |
C.clear commands make kids different |
D.choice of words can make a difference |
【推荐2】What are dreams for? Sigmund Freud famously claimed that they reveal hidden truths and wishes. More recent research suggests that they may help us process intense emotions, or perhaps classify(分类) and consolidate(巩固) memories, or make sense of random neuron(神经) activity, or rehearse(排练) responses to threatening situations. Other believe that dreams have no evolutionary(进行的) function, but simply dramatize personal concerns.
Despite being largely unsupported by evidence, Freud’s view maintains a strong following around the world. Researchers found that students in the U.S., South Korea, and India were much more likely to say that dreams reveal hidden truths than to endorse better-substantiated(证实的) theories. In the same study, respondents said that dreaming about a plane crash would cause them more anxiety than an official warning about a terrorist attack.
Even if dreams can't foretell(预知) the future, they seem to expose our shared fascinations. The majority of dreams occur during REM sleep cycles(快速动眼期), of which the average person has four or five a night. A study of Canadian university students found the most common dream topics to be school, falling, being chased, and arriving too late for something.
For all the commonalities dreams exhibit, they vary across time—people who grew up watching black-and-white TV are more likely to dream in black and white—and culture. A 1958 study determined that compared with Japanese people, Americans dreamed more about being looked up, losing a loved one, finding money, being inappropriately dressed, or encountering an insane person. Japanese people were more likely to dream about school, trying repeatedly to do something, being paralyzed with fear, or "wild, violent beasts."
But even negative human dreams can have positive effects. In a study of students taking a French medical-school entrance exam, 60 percent of the dreams they had beforehand involved a problem with the exam, such as being late or leaving an answer blank. But those who reported dreams about the exam, even bad ones, did better on it than those who didn't.
So the next time you dream about an education-related experience in which you are both falling and being chased, don’t worry: It’s probably totally meaningless. Then again, your brain might be practicing so you’ll be ready if such an event ever comes to pass.
1. According to different theories mentioned in the passage, dreams may help people in various aspects EXCEPT ________.A.healing the body | B.memory classification |
C.preparation for a dangerous situation | D.understanding random neuron activity |
A.check | B.advertise |
C.support | D.measure |
A.People all dream in black and white without any other color. |
B.Humans have the longest REM sleep cycles among all animals. |
C.Our dreams often reflect our emotions or anxieties in many forms. |
D.People feel more stressed when encountering emergencies in reality than in dream. |
A.what you experience in dreams usually turns out to be the opposite |
B.bad dreams can help us prepare beforehand to perform better in reality |
C.it is a kind of comfort and relief to think dreams are usually meaningless |
D.dreaming about bad things enhances(提高) our bravery and helps to drive away our fears |
【推荐3】Many people are familiar with the horrible images of wildlife—including sea turtles, dolphins and seals—trapped in abandoned fishing nets. The main issue behind Nylon-6, the plastic inside these nets, carpet and clothing, is that it’s too strong and durable to breakdown on its own. So, once it’s in the environment, it exists for thousands of years, littering waterways, breaking corals and killing birds and sea life.
Now, Northwestern University chemists have developed a new catalyst (催化剂) that quickly, cleanly and completely breaks down Nylon-6 in a matter of minutes—without generating harmful byproducts. More importantly, the process does not require poisonous solvents (溶剂), expensive materials or extreme conditions, making it practical for everyday applications.
Current methods to dispose of Nylon-6 are limited to simply burying it in landfills. When Nylon-6 is burned, it produces poisonous pollutants such as nitrogen oxides. Although other labs have explored catalysts to degrade Nylon-6, those catalysts require extreme conditions (such as temperatures as high as 350 degrees Celsius), high-pressure steam (which is energetically expensive and inefficient) and/or toxic solvents that only contribute to more pollution.
To bypass these issues, the researchers looked to a novel catalyst already developed in the lab of Tobin Marks, the leader of the research. The catalyst takes advantage of yttrium—an inexpensive Earth-abundant metal. When the team heated Nylon-6 samples to melting temperatures and applied the catalyst without a solvent, the plastic fell apart—returning to its original building blocks without leaving byproducts behind. In experiments, Marks and his team were able to recover 99% of plastics’ original building blocks.
“Our research represents a significant step forward in the field of polymer recycling and sustainable materials management,” said Marks. After filing a patent for the new process, Marks and his team have already received interest from many potential industrial partners. They hope others can use their catalysts on a large scale to help solve the global plastic problem.
