    Exams never made me break out in a nervous sweat with tears threatening to ruin my already-trembling façade — but this one did. Even booking my piano exam reduced me to a blubbering mess of anxiety.

I feel permanently scarred inside churches — no longer admiring their beauty because, over the years, I have received such terrible marks from examiners hiding behind the stained-glass partitions. Despite being 15 — too old, too cool to be frightened — I remember trembling inside the bathroom stalls before my tests. I wished I never had to play in front of others.

But this time, after booking my Level 8 Royal Conservatory of Music piano exam, I went back to my normal routine. A little practice here, a little practice there. And then it happened.

My trusty, 10-year-old electric piano gave out. Middle C started to sound like an F-sharp and all other keys sounded like they were a fourth above their natural tone. Thankfully, my precious, boredom-saving buttons still worked. I could still change my piano’s settings from “piano” to “harpsichord .” I admit, it was a lot of fun banging on my wacky keys. Each note bonged like the sound on children’s TV shows when a character repeatedly runs into a wall.

Goofiness aside, I had to get my act together. I hated practicing but I really wanted a good mark. When I told my father what had happened to my piano, he only glared at me with disappointment, “When I was your age, I learned to be resourceful.”

Hmm. I had a broken piano, an exam coming up in a few months and a father who refused to buy me a new piano because he wanted to teach me a “life lesson”. I finally came upon a decision: I’d practice at school.

Going to a private school had to have its benefits, so I looked for a place to play. The school had many pianos but only a few in tune. Within a few days of searching, my piano books, my artistic best friend and I headed off to a music room at every available opportunity.

I loved finding new pianos in hidden corners of the school and I laughed at the dusty old historic pianos. They really had character. I spent hours in those music rooms while my friend honed her art skills in sketching and drawing. She suffered through my annoying, repetitive scales while I looked over my shoulder once in a while and admired her work. Not only did I become a better musician, but I also managed to gain a few subpar skills as an art critic.

As my exam drew close, all the music teachers knew to look for me in the piano rooms during recess, after school and late on Fridays. In anticipation of my assessment, one of my music teachers let me perform for her as a mini practice exam. To my surprise, she was greatly impressed.

Within a few months I went from not caring about my playing to feeling actually, maybe, kind of proud of my work. And over countless hours spent in my favorite, soundproof music room, I discovered that behind the piano, I could become anyone. Talking to other people never came easy to me, but I was able to express myself through music. I became overjoyed. It was like I had developed a sixth sense, one that only musicians could understand.

When I played, my worries about what others thought of me and how I viewed myself merged to reveal who I really am. All my adolescent musings made me feel like I was in a cage, but music gave me the key. Sitting behind a piano and creating music combined the movement of my body and the inner workings of my heart.

Music had never been the love of my life but that was changing. I loved the idea of being on a stage and creating something for others to enjoy and remember. Actually, it wasn’t a something, but rather a feeling that the audience would carry outside into a world where music wasn’t the only thing that people cared for.

When the time came to play in front of an examiner, instead of fearing my judge, I feared nothing but being unable to represent all my hard work. All the anxiety I had about going up on stage dimmed, and when the lights went on, all I could think about was the marvellous journey I’d had to get here. Trilling the keys reminded me of when I’d spent nearly two hours alone in a music room, more content than I had been anywhere else. Playing the melody reminded me of the bittersweet music experiences of past years.

Many days later, I received my mark. Not only did I earn a rarely mentioned “well done” and an 82 per cent, I had rewritten what music meant to me.

Now whenever I get caught up in the daily struggle, I remember the hard work that it took to reach my goal. Whenever I feel discouraged, I never forget to look at the gleaming keys of my new upright piano. As my father always says, some lessons are just learned the hard way.

    For some people, higher education is not just a goal in life, but also an expectation. In the United States, if your parents attended a college or university, there is a good chance that you will, too. Even if your parents did not go to college, you still have a good chance of completing higher education if your family is wealthy.

But your chances are reduced if you come from a needy family, a community with limited educational resources or you simply have no one to follow as an example.

Helping those in need is one of the main ideas behind a strategy of behavioral science called nudge theory or nudging. Nudging is a way of changing people's behavior through indirect suggestion and by supporting positive actions.

A growing number of U.S. colleges and universities look to nudging as a way to support poor, minority and first-generation students. They also are using it to increase overall graduation rates. Two common forms of nudging are emails to students and text messages to their mobile phones. Schools and other educational organizations keep in contact with students this way, offering advice and help when needed.

However, Alejandra Acosta — a higher education policy expert at New America — notes that there are several qualities a nudge campaign must possess in order to be successful.

Acosta says messages must be timely, meaning they reach college students well before the date by which a student is required to take action. Additionally nudges should be written clearly and provide as much information as possible. If students start to struggle in class, school officials should not just message them, saying they should seek academic support. The message should give information about what kinds of support the college or university offers and exactly how the student can make use of them. That is why nudges should possess interactive qualities, Acosta says. For example, students should be able to ask questions of school officials or be directed to a website for more information. In addition, colleges and universities must ensure their support services are in place and working as best they can.

When nudges work, they can do a lot of good. In 2018, a nonprofit group launched a nudging campaign at four U.S. community colleges. They worked with nearly 10.000 first-year students at three such colleges in Ohio and one in Virginia. A recent study found that older and minority students who agreed to receive these nudges were 16 to 20 percent more likely to continue into their second year than those who did not.

B.Jimmy, whose mother is a worker in a small factory.

C.Betty, whose grandmother is a housemaid of a famous university professor.

D.Cathy, whose parents failed to attend college but succeeded in starting a big company.

2.What can we know about nudging?

C.It offers concrete and direct advice.

D.It helps students via emails and text messages.

3.What is the passage mainly talking about?

A.The problem with higher education.

    Scientists have discovered a “monster black hole” so massive that, in theory, it shouldn’t exist. It’s a stellar (恒星) black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel (排出) matter and gas swept away by stellar winds.

This theory has now been toppled by LB-1, the newly discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.

The findings were published by Chinese researchers in the journal Nature on Wednesday. “Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,” said Liu Jifeng, head of the team that made the discovery.

“LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation.”

Scientists are now scratching their heads at how LB-1 got so huge.

The Chinese team has proposed a number of theories. LB-1’s sheer size suggests that it “was not formed from the collapse of only one star,” the study said — instead, it could potentially be two smaller black holes orbiting each other.

Another possibility is that it formed from “fallback supernova.” This is when a supernova — the last stage of an exploding star — ejects (排出) material during the explosion, which then falls back into the supernova, creating a black hole.

This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have “direct evidence for this process” for the first time, the study said.

There are several types of black holes and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger — they can be billions of times the mass of our sun.

Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the mass star stems but it is still not clear exactly how, or which form first.

1.Why does the writer write the article?

A.To report the great achievement Chinese scientists have made in black hole theory.

B.To inform the readers of the basic knowledge about the black hole.

C.To share with the readers the new development of the black hole discovery.

D.To demonstrate the significance of discovering new black holes for science.

2.What does the underlined word “toppled” mean in the second paragraph?

A.overturned B.supported C.suspected D.tested

3.Which of the following about LB-1 is true to the passage?

A.It is the biggest black hole ever discovered.

B.It lost only a small part of its mass through explosion.

C.It couldn’t have been formed from the collapse of one star,

D.Its discovery may lead to some breakthrough in the “fallback formation theory”.

4.Which of the following is right according to the passage?

A.If the sun in our galaxy dies some of its mass will be taken away by stellar winds.

B.A massive supernova will be formed and then exploded if the sun in our galaxy dies.

C.“The Milky Way” was formed after a supermassive black hole collapsed and exploded.

D.If “the Milky Way” dies, a supermassive black hole will be formed after its death.
