四、阅读理解
A篇
Numbers are more than just tools for counting—they shape how we see the world. Ancient people used numbers to track seasons, trade goods, and build great structures. For example, the Egyptians used simple numbers to design the pyramids, making sure each side was perfectly balanced.
In many cultures, numbers have special meanings. In China, the number 8 is considered lucky because it sounds like the word for "prosperity". In Western countries, 13 is often thought to be unlucky. But these ideas are just traditions—numbers themselves don’t bring good or bad luck.
Numbers also help us understand nature. A snail’s shell has a spiral (螺旋) pattern that follows the "Fibonacci sequence" (斐波那契数列), where each number is the sum of the two before it (1, 1, 2, 3, 5, 8...). This pattern is also seen in sunflowers and pinecones.
Today, numbers are everywhere in our lives. From phone numbers to bank codes, they help us organize information. Scientists use complex numbers to predict weather, while students learn basic numbers to solve math problems. No matter how we use them, numbers are a universal (普遍的) language that connects people around the world.
1. Why did ancient Egyptians use numbers
A. To bring good luck B. To design pyramids C. To predict weather D. To count lucky numbers
2. The underlined word "prosperity" in Paragraph 2 probably means ______.
A. bad luck B. good fortune C. hard work D. careful planning
3. Which of the following follows the Fibonacci sequence
A. 1, 2, 3, 4, 5 B. 2, 4, 6, 8, 10 C. 1, 1, 2, 3, 5 D. 3, 6, 9, 12, 15
4. What can we learn from the passage
A. Numbers have the same meaning in all cultures.
B. The Fibonacci sequence is only found in snail shells.
C. Numbers help people in both ancient and modern times.
D. Scientists use numbers mainly for trading goods.
5. What is the best title for the passage
A. Lucky Numbers Around the World B. The History of Egyptian Pyramids
C. Numbers: More Than Just Counting D. How to Learn Math Easily
B篇
Chess is a game of strategy (策略) that has been played for over 1,500 years. It began in northern India and spread to Europe, where it evolved (演变,发展) into the game we know today. The goal is simple: capture the opponent’s king. But achieving this requires patience, foresight (远见), and logical thinking.
Each chess piece moves in a unique way. The queen, for example, can move any number of squares horizontally (水平地), vertically (垂直地), or diagonally (对角线地), making her the most powerful piece. The king, however, can only move one square in any direction, so protecting him is key. Pawns, the smallest pieces, move forward but capture diagonally—their limited movement teaches players to plan ahead.
Studies show that playing chess improves cognitive (认知的) skills. A research project in Spain found that students who played chess regularly scored higher in math and problem-solving tests. The game forces players to think about consequences: every move can lead to a chain of reactions, so impulsive decisions often backfire (产生事与愿违的结果).
Chess is also a sport of the mind. Professional players train for hours daily, analyzing past games and practicing strategies. The World Chess Championship, held every two years, attracts millions of viewers worldwide. In 2018, Magnus Carlsen defended his title by defeating Fabiano Caruana, showing that even the best players must adapt (适应) and learn from their mistakes.
Like life, chess is not just about winning—it’s about learning from each move. As the chess master Bobby Fischer once said, "You don’t get good at chess by playing weak opponents (对手). You have to play people better than you."
6. Where did chess first appear
A. In Europe B. In northern India C. In Spain D. In ancient Egypt
7. The underlined word "impulsive" in Paragraph 3 is closest in meaning to ______.
A. careful B. sudden C. wise D. patient
8. What can we infer from the passage
The queen is the most important piece because she protects the king.
B. Playing chess can help students perform better in certain subjects.
C. Professional chess players only need to practice their own strategies.
D. The World Chess Championship is held every year.
9. What is the main idea of Paragraph 4
A. Chess requires daily practice to win championships
B. Professional chess is a mind sport with global charm
C. Magnus Carlsen is one of the best chess players
D. The World Chess Championship has a long history
10. Which of the following would Bobby Fischer most likely agree with
A. Chess is too difficult for beginners.
B. You should avoid strong opponents to win.
C. Learning from stronger players improves your skills.
D. Winning is the only goal in chess.

Numbers are more than just symbols on a page—some have amazing stories and uses. Let’s explore a few that might surprise you!
1._______ For example, the number 0 was invented in India over 1,500 years ago. Before that, people had no way to represent "nothing" in math. This simple idea changed how we calculate and even helped create computers!
Another interesting number is 12. 2._______ We have 12 months in a year, 12 hours on a clock, and even 12 inches in a foot. No one is sure why 12 became so popular, but it’s easy to divide by 2, 3, 4, and 6—maybe that’s the reason!
3._____ It’s called "pi" (π) and is about 3.14. Pi is used to calculate the circumference (周长) of circles. What’s amazing is that pi goes on forever—scientists have found over 100 trillion digits, and there’s no end in sight!
Some numbers are famous in culture. In Japan, 4 is unlucky because it sounds like the word for "death".
4._______. Many buildings skip the 4th floor, just like some Western buildings skip the 13th floor.
5._______From the smallest atoms to the largest galaxies, numbers help us understand the world. Next time you see a number, stop and think—maybe it has a secret story!
