Amazing Numbers in Sports
Sports and numbers are closely connected. From scores to statistics, numbers help us understand and enjoy sports better. There are many amazing numbers in sports that surprise people.
In football, the World Cup is a big event. The number of teams that take part in the final stage of the World Cup is 32. But do you know how many countries compete for these 32 spots It's more than 200! The average number of goals scored in a World Cup match is about 2.5. That means fans can usually see at least two goals in a game.
In basketball, Michael Jordan is a legendary player. He has won 6 NBA championships and 5 NBA Most Valuable Player Awards. His average score per game in his career is about 30.1 points, which is one of the highest in NBA history. Another amazing number in basketball is the height of the basket. It's always 3.05 meters, no matter which country or court you are on.
In tennis, the Grand Slam tournaments are the most important events. A player who wins all four Grand Slam titles in one year is said to have achieved a “Grand Slam”. Only a few players in history have done this. The number of sets in a men's Grand Slam final is usually 5, while for women it's 3. The fastest serve in tennis history was recorded at 263.4 kilometers per hour, which is an amazing speed.

The Mystery of Prime Numbers
Prime numbers are some of the most amazing numbers in mathematics. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. For example, 2, 3, 5, 7 and 11 are all prime numbers.
People have been interested in prime numbers for a long time. Ancient Greek mathematicians studied prime numbers more than 2,000 years ago. Euclid, a famous Greek mathematician, proved that there are infinitely many prime numbers. This is a very important discovery because it shows that we will never run out of prime numbers to study.
Today, prime numbers have many practical uses. One of the most important uses is in cryptography, which is the science of keeping information secret. When we shop online or send private messages, prime numbers help keep our information puters use large prime numbers to create codes that are hard to break. The larger the prime numbers used, the safer the codes are.
But there are still many mysteries about prime numbers that haven't been solved. For example, the “Twin Prime Conjecture” says that there are infinitely many pairs of prime numbers that differ by 2, like (3,5), (5,7) and (11,13). Although many mathematicians have worked on this problem, no one has been able to prove it yet.
Another mystery is the distribution of prime numbers. As numbers get larger, prime numbers become less common, but no one has found a perfect pattern to predict where the next prime number will be. Mathematicians use complex formulas and computer programs to find large prime numbers. The largest known prime number so far has more than 24 million digits! It was discovered in 2022 by a group of mathematicians using a special computer program.Prime numbers are not only important in mathematics but also in our daily lives. They help keep our digital world safe and continue to challenge mathematicians with their mysteries.
( )1. What is a prime number
A. A number greater than 1 that has many positive divisors.
B. A number greater than 1 that has only 1 and itself as positive divisors.
C. A number less than 1 that is used in cryptography.
D. A number that is the sum of two other numbers.
( )2. Who proved that there are infinitely many prime numbers
A. A modern mathematician.
B. A Chinese mathematician.
C. Euclid, a Greek mathematician.
D. A group of mathematicians in 2022.
( )3. What is one of the practical uses of prime numbers today
A. Predicting the weather.
B. Keeping digital information safe.
C. Calculating the speed of light.
D. Measuring the height of mountains.
( )4. What is the “Twin Prime Conjecture”
A. There are infinitely many prime numbers.
B. The largest prime number has 24 million digits.
C. There are infinitely many pairs of prime numbers that differ by 2.
D. Prime numbers become more common as numbers get larger.
( )5. What can we learn from the passage
A. Prime numbers have no mysteries now.
B. The largest known prime number was discovered in 2022.
C. Prime numbers are not useful in our daily lives.
D. The distribution of prime numbers has a perfect pattern.
