My Favorite Hobby
My favorite hobby is reading. I started when I was seven, thanks to my mom who gave me a picture book about animals. At first, I read simple stories with colorful pictures. As I grew up, I began borrowing novels from the library—my favorite is The Little Prince.
Reading helps me in many ways. It improves my vocabulary: I often write down new words in a notebook and look them up. It also teaches me about different cultures—last month, I read a book set in Japan and learned about tea ceremonies. When I’m stressed, reading takes me to another world, making me forget my worries.
To make reading more fun, I join a book club at school. We discuss our favorite stories and recommend books to each other. I also set a goal: read one new book every two weeks.
Reading is more than a hobby—it’s a friend that teaches, entertains, and inspires. I hope to keep reading all my life./ 让教学更有效 高效备考 | 英语学科

五、阅读理解（20 分）
Passage 1
Lisa has been looking forward to the summer holiday for months. Ever since her dad mentioned teaching her to swim, she’s been counting down the days. She’s always loved being in the water, but never had the chance to learn properly. To prepare, she borrowed three books about swimming from the city library—one on basic strokes, one on breathing techniques, and another with fun water games. She’s read them cover to cover, highlighting important tips like keeping your body streamlined and exhaling slowly underwater.
Last Saturday, Lisa had her first lesson at the community pool. Her dad, a former swimmer in high school, started with the basics: floating on her back and kicking her legs. At first, everything felt awkward. She kept tensing up, which made her sink. Then, when she tried to put her face in the water, she ran into a big problem—she couldn’t breathe evenly. Panic set in, and she had to stand up to catch her breath.
“Don’t worry,” her dad said gently. “Breathing is the hardest part. Let’s practice with your face just above the water first. Blow bubbles through your mouth, then turn your head to inhale. Have a go at it ten times, and you’ll get the hang of it.” Lisa followed his advice, and by the end of the hour, she could float for 30 seconds without sinking.
This week, she’s been practicing every evening after school. She even asked her mom to time her, trying to beat her own record. “I hope I can swim 50 meters by the end of the holiday,” she wrote in her diary. “It’s tough, but every small win feels amazing.”
Lisa’s friends have noticed her excitement. “Can we come watch you swim sometime ” asked Mia, her best friend. “I’d love to,” Lisa replied. “Maybe by then, I can teach you a few tricks!”
( )41. Why did Lisa borrow books from the library
A. To learn about swimming history
B. To prepare for her swimming lessons
C. To find water games to play with friends
D. To read stories about famous swimmers
( ) 42. What was Lisa’s first problem in the swimming lesson
A. She couldn’t float on her back
B. She couldn’t kick her legs properly
C. She had trouble breathing underwater
D. She was afraid of deep water
( ) 43. How did Lisa’s dad help her with breathing
A. He made her swim 50 meters first
B. He taught her to blow bubbles and inhale slowly
C. He told her to hold her breath for 30 seconds
D. He let her practice in shallow water alone
( ) 44. What does Lisa hope to achieve by the end of the holiday
A. To teach her friends to swim
B. To win a swimming contest
C. To swim 50 meters
D. To read all swimming books

A. Discouraged by her mistakes
B. Proud of every small success
C. Bored with daily practice

Passage 2
Many students stay up late to study, especially before exams. They think sacrificing sleep will help them remember more information, but science tells a different story. A study by the University of California tracked 500 middle school students for a year, comparing their sleep habits with their test scores. The results were clear: students who slept 7-9 hours nightly scored 20% higher on average than those who slept less than 6 hours.
Why is sleep so important During deep sleep, the brain reviews and stores information from the day, turning short-term memories into long-term ones. This process is like filing papers—without it, your brain becomes too cluttered to find what it needs. Students who pull all-nighters might cram facts temporarily, but most will forget them within days.
Lack of sleep also affects mood and focus. Teachers often report that sleep-deprived students are more irritable, struggle to sit still, and miss important instructions. “I used to stay up until 2 a.m. studying,” said 14-year-old Jason. “But then I’d zone out in class and have to ask friends for notes. Now I go to bed at 10 p.m., and I get more done in less time.”
Our school library has plenty of books on sleep science, including Teens and Sleep by Dr. Maria Gomez. It explains how screens disrupt sleep hormones, why regular bedtimes matter, and simple relaxation techniques. The school nurse also offers “sleep workshops” every month, teaching students to create a bedtime routine: no phones an hour before bed, reading a physical book, or listening to calm music.
“Sleep isn’t a waste of time,” the nurse told a group of students last week. “It’s the best study tool you have. Your brain works harder while you sleep than you think!”
( ) 46. What did the University of California study find
A. Students who sleep less score higher
B. Sleep helps with long-term memory
C. 500 students failed their exams
D. Studying at night improves focus
( ) 47. Why is deep sleep compared to “filing papers”
A. It organizes and stores memories
B. It cleans the brain of useless information
C. It helps students write better essays
D. It makes room for new facts
( ) 48. How did Jason’s grades change after adjusting his sleep
A. He scored 20% lower than before
B. He had to ask friends for notes
C. He became more efficient in studying
D. He forgot information faster
( ) 49. What does Dr. Gomez’s book explain
A. How to study all night effectively
B. Why screens affect sleep quality
C. Ways to stay awake during classes
D. How to memorize facts quickly
( ) 50. What is the main message of the passage
A. All students need 9 hours of sleep nightly
B. Sleep is more important than studying
C. Good sleep improves learning and health
D. Schools should ban late-night studying
Passage 3
Jack taught himself to play the guitar when he was 12. It started with a dusty old guitar in his grandpa’s attic—brown, with a few scratches, but still playable. “Why don’t you try it ” his grandpa suggested. “I taught myself to play at your age.” Jack was curious, so he took it home.
The first week was frustrating. His fingers hurt from pressing the strings, and he couldn’t play a single chord properly. He wanted to give up, but then he found free tutorials online. “There are hundreds of videos on YouTube,” he said. “I watched one every night, pausing to practice each step.”
Jack focused on simple songs first—Happy Birthday and Twinkle Twinkle Little Star. He practiced for 30 minutes daily, even when his fingers ached. After three months, he could play Let It Be by The Beatles, his favorite song. “My mom recorded me and sent it to grandpa,” he said. “He called me crying—said it was the best gift ever.”
Now 14, Jack plays in his school’s music club. His teacher, Ms. Lee, says his skills set him apart from other students. “He has a natural feel for rhythm, which you can’t always teach,” she said. “And he’s always helping others—showing them how to hold the guitar or change chords.”
Jack still practices daily, often staying up late on weekends to learn new songs. “Music helps me express myself,” he said. “When I’m stressed about exams, playing for an hour makes everything better. It’s like having a friend who listens without judging.”
This year, he’s teaching his little sister to play. “She’s 8, and her fingers are too small for some chords,” he laughed. “But we take it slow—just like I did. Who knows Maybe we’ll start a band someday.”
( ) 51. Where did Jack get his first guitar
A. From a music store
B. From his grandpa’s attic
C. From his school music club
D. From his mom as a gift
( ) 52. How did Jack learn to play the guitar

B. By watching online tutorials
C. By joining a guitar competition
D. By reading music books
( ) 53. What song could Jack play after three months

B. Twinkle Twinkle Little Star
C. Let It Be
D. A song he wrote himself
( ) 54. Why does Ms. Lee think Jack is different from other students

B. He plays more songs than others
C. He has a expensive guitar
D. He never makes mistakes
( ) 55. What does Jack say about music

C. It’s only fun with a band
D. It’s too hard for young kids
Passage 4
Next week, our school is taking 200 students on a trip to the City Science Museum—the first big outing since the start of the semester. Teachers have been preparing for weeks, and excitement is building in every classroom.
The museum is famous for its interactive exhibits. There’s a “Space Station” where you can simulate zero gravity, a “Dinosaur Hall” with life-sized models that move and roar, and a “Chemistry Lab” where students can do simple experiments (with adult supervision). “We’ll split into groups of 10,” said Mr. Chen, the science teacher. “Each group will have a chaperone and a map of the exhibits. Stick together, and follow the rules—no running, no touching fragile displays, and pay attention to your chaperone’s instructions.”
Lunch will be at the museum’s café, but students can bring snacks if they prefer. “There are plenty of seating areas,” said Ms. Wang, the trip organizer. “We’ll meet at 1 p.m. in the main hall before heading back to school.”
Photography is allowed in most areas, but flash is banned—bright lights can damage old fossils and paintings. “Take as many photos as you want,” said Mr. Chen. “But turn off that flash! And don’t post them online until we’re back—we want to surprise the students who couldn’t come.”
The school sent a list of reminders home: wear comfortable shoes (you’ll walk 3-4 miles), bring a water bottle, and leave electronics in your bag during exhibits. “This trip is about exploring, not scrolling,” said Principal Liu in the morning announcement.
Students are already asking questions. “Can we buy souvenirs ” asked Tim. “The gift shop has small items like dinosaur stickers and astronaut keychains,” replied Ms. Wang. “But bring only a little money—you won’t need much.”
