4 . Nuclear bombs. That’s the go-to answer for incoming space objects like asteroids (小行星) and comets as far as Hollywood is concerned. Movies like Deep Impact and Armageddon rely on nuclear weapons, delivered by stars like Bruce Willis, to save the world and deliver the drama.

But planetary defense experts say in reality, if astronomers spotted a dangerous in-coming space rock, the safest and best answer might be something more subtle, like simply pushing it off course by crashing it with a small spacecraft.

That’s just what NASA did on Monday evening, when a spacecraft headed straight into anasteroid called Dimorphos, which is around 7 million miles away and poses no threat to Earth. It’s about 525 feet across and orbits another larger asteroid.

In images streamed (传输) as the crash neared, the egg-shaped asteroid grew in size from a little spot on screen to have its full rocky surface come quickly into focus before the signal went dead as the craft hit right on target.

Events happened exactly as engineers had planned, they said, with nothing going wrong. “As far as we can tell, our first planetary defense test was a success,” said Elena Adams, the mission systems engineer, who added that scientists looked on with “both terror and joy” as the spacecraft neared its final destination.

The crash was the peak of NASA’s Double Asteroid Redirection Test (DART), a 7-yearand more than $300 million effort which launched a space vehicle in November of 2021 to perform humanity’s first-ever test of planetary defense technology. It will be about two months, scientists said, before they will be able to determine if the crash was enough to drive the asteroid slightly off course, probably shortening its original orbit.

NASA plans to launch an asteroid-hunting space telescope named NEO Surveyor in 2026. “We’ve tracked lots of space rocks, especially the larger ones that could cause extinction-level events. Thankfully, none currently threaten Earth. But many asteroids the size of Dimorphos haven’t yet been discovered, and those could potentially take out a city if they came crashing down,” explains Lindley Johnson, NASA’s Planetary Defense Officer.

7 . One Friday evening in December, two weeks before Christmas, I lost my job without any warning. I was ________ for the weekend, when my daughter Kristil and I ________ to get our Christmas tree. Then I listened to my voicemail: “We’re sorry but your work assignment has ended as of today.” My heart ________.

I wasn’t just a single parent; I was the only parent. My paycheck was ________.

The next day as we searched for our tree, I struggled to be cheerful as I ________ each price tag (标签). Over the next week, I ________ applied for jobs as my bank account grew smaller. On a weekend afternoon, I dropped Kristil in a ________ gated community for a birthday party. I watched as she went in, surrounded by all the nice things we couldn’t afford. I drove home ________.

Back at home, I glanced out the window. It had been snowing on and off all morning. I _________ a small elderly woman with short white hair struggling to open her car door _________ the wind. As she got out, I realized it was my old professor, Sister Esther Heffernan, whom I hadn’t seen for about six months.

“What are you doing out in this weather?” I asked as we hugged. “Well, I tried to call last week but couldn’t ________. Then I called your job and they said you weren’t working there anymore, so I thought I would come by.”

Just being in Sister Esther’s ________ gave me hope that things would be all right. As she got up to leave, she handed me a Christmas card and kissed me on the cheek. I walked her to her car and ________ as she drove away.

When I opened her card, I gasped (喘气) in ________. Hundred-dollar bills fell onto the table. Tears of ________ welled up in my eyes as I counted. I silently thanked her in my heart.

“Hurry up you guys, or you will be late for school!” called Mom. We went downstairs and had a quick breakfast. I was eating my favorite — very sweet porridge, and Sara was. having eggs. When I rose to have my bowl washed, Mom whispered, “You know you need to be cautious today when you’re walking Sara to school. It’s your job to assure (保证) me she gets there all right.” Then she cast me. a very serious look. I thought to myself, wondering why Mom was making such a big deal out of this. It was Sara’s first day of Kindergarten, but I could manage it. I wish Mom would treat me like an adult.

Then Sara ran out of the house, and I went behind her, skipping down the front walkway to the sidewalk. Along the way, I could feel Mom’s gaze on us.

I grabbed Sara’s hand. “Are you eager and excited for your first day of school?” I asked, trying to sound like a grown-up. Sara smiled and nodded her head yes. Meanwhile, my mom was staring at us through the window. “When will she treat me like an adult?” I thought. “I will show you the way.” I said. I felt proud to be the elder sister. We walked past beautiful gardens and big, leafy trees. Suddenly, I heard a growl (低吼) and saw a dog walking towards us. He was big and fierce looking with long sharp teeth. “GRRRR!!!” the dog barked. I didn’t see its owner or anyone who could help us. My hand became sweaty and Sara stopped walking. “I’m scared, Julie,” she said. I didn’t want her to be scared. I wanted to appear brave. “Everything will be okay,” I said.

“GRRRR!!!” The dog stepped closer and we could see it was the size of a small horse — with red eyes and sharp teeth.

9 . Every Saturday morning Phoenix Young would take piano lessons with a family friend when he was a child. “At that time we would_______around and take all morning just to have a lesson,” Phoenix_______. “And I loved it.”

But when Phoenix was 12, his teacher proposed that he need better_______.So his mother took him to a music school in the Bronx, and signed him up for classes with a teacher named Bade Simon, experienced bit known for being _______. And she quickly lived up to that _______.Phoenix found the stressful life was_______like his lighthearted Saturday mornings with his former teacher, so it wasn’t long before he_______that he would quit.

One day, however, Bade_______him and said something surprising: “I have_______in you. Keep going. Then the reluctant (不情愿的) student did something surprising ________: he said, “Okay.”

“It was as if all I wanted was just a________from her that she cared about me,” Phoenix said.

That moment________their relationship. Within a few weeks, they were having________during lessons. And within a few months, she was teaching him things about music that he’d never known before. It was the beginning of a long and fruitful relationship.

“I went into________and became a piano teacher, a career I have been doing for 50 years,” Phoenix said. “And I ________it all to that precious moment with my unsung hero, Bade Simon.”

Once upon a time a daughter complained to her father that her life was miserable and that she didn’t know how she was going to make it.She was tired of fighting and struggling all the time. It seemed just as one problem was solved, another one soon followed. Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire.

Once the three pots began to boil, he placed potatoes in one pot, eggs in the second pot and ground coffee beans in the third pot. He then let them sit and boil, without saying a word to his daughter. The daughter complained and impatiently waited, wondering what he was doing. After twenty minutes he turned off the burners. He took the potatoes out of the pot and placed them in a bowl. He pulled the eggs out and placed them in a bowl. He then ladled (舀) the coffee out and placed it in a cup.

Turning to her, he asked, “Daughter, what do you see?”“Potatoes, eggs and coffee,” she quickly replied.

“Look closer,” he said, “and touch the potatoes.” She did and noted that they were soft.

He then asked her to take an egg and break it. After pulling off the shell, she observed the hard-boiled egg.

Finally, he asked her to sip the coffee. “Father, what does this mean?” she asked.

He then explained that the potatoes, the eggs and the coffee beans had each faced the same boiling water. However, they reacted differently. The potatoes were in strong and hard, but in the boiling water, they became soft and weak. The eggs were fragile (易碎的), with the thin outer shell protecting their liquid inside until they were put in the boiling water. Then the inside of the eggs became hard. However,the ground coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new.

“Which one are you?” he asked his daughter. “When the disaster knocks on your door, how do you respond?Are you a potato, an egg, or a coffee bean?”

“Father, I   want to be a coffee bean,” said the daughter,

In the end, she understands that
