A篇：Numbers in Daily Life
Numbers are everywhere in our daily life. When you check a flight schedule, you see departure times like 8:15 or 14:30. The price tag on a shirt might say 199 yuan, and a budget for a trip could be 5,000 yuan.
In school, 60 percent is often the passing mark for a test. If you get 90 percent, you’ll probably get a prize. When counting books in the library, you might find there are 2,000 storybooks and 500 science books.
Numbers help us organize our lives. Without them, we couldn’t tell time, check prices, or plan schedules. They are truly amazing!

B篇：Numbers in Population
Currently, the world’s population is over 8 billion. Some countries have large populations—for example, China has about 1.4 billion people, which is 18 percent of the world’s total.
Population can change sharply. A province with 5 million people now might have 6 million in 10 years. Some areas see numbers go up because more people move there; others see numbers go down as people leave.
Governments use these numbers to plan: building 20 new schools for a growing population, or 5 new hospitals. Numbers help them make good decisions.
6. What is the world’s current population
A. Over 8 billion B. 1.4 billion C. 5 million D. 6 million
7. What percent of the world’s population does China have

Numbers Around Me
Numbers are everywhere in my life. The flight schedule for my trip shows the plane leaves at 8:30. The price tag on my new notebook is 15 yuan, and my weekly budget is 50 yuan.
In school, the 3rd lesson is math, where we learn to count. I got 95 percent in the last test and won a small prize. Currently, our class has 40 students—22 boys and 18 girls.
I often write down important numbers, like the 1st of every month for library books. Numbers help me check schedules and plan my day. They are really amazing!
