You may not know the name Fibonacci, but you can easily find Fibonacci numbers in nature.

Fibonacci was a great Italian mathematician. Almost 800 years ago, he put forward a special sequence (数列) of numbers. It starts with 1 and 1. Each new number is the sum of the two numbers before it. So the sequence is 1, 1, 2, 3, 5, 8, 13, 21, …

You might think these numbers are just a game for mathematicians. In fact, they are everywhere in the natural world. Look at the seeds in a sunflower. They grow in two groups of spirals (螺旋). One group turns clockwise, the other counterclockwise. Usually the number of spirals is a Fibonacci number. Pinecones (松果) also follow this rule. The number of their scales (鳞片) is one number from this sequence.

Scientists are still not sure why nature chooses Fibonacci numbers. One possible idea is that this way helps plants grow better. Seeds and leaves will not cover each other. They can get more sunshine and rain.

Today Fibonacci numbers are not only used in biology. People also use them in computer science, painting and building design. This old math sequence still surprises us today.

11. Where did Fibonacci come from?

A. France. B. Italy. C. England. D. Germany.

12. What is the next number after 13 and 21 in the Fibonacci sequence?

A. 28. B. 30. C. 34. D. 42.

13. What example of Fibonacci numbers in nature is mentioned in the passage?

A. Sunflower seeds. B. The height of trees.

C. The colour of flowers. D. The size of leaves.

14. Why may plants use Fibonacci numbers when they grow?

A. To grow much faster in winter. B. To stop seeds and leaves covering each other.

C. To make themselves more beautiful. D. To help them move from place to place.

15. Which of the following is TRUE?

A. Fibonacci lived about 200 years ago. B. The Fibonacci sequence starts with 1 and 2.

C. We can only find Fibonacci numbers in nature. D. Fibonacci numbers can be used in many different fields.

World Wildlife Day falls on March 3rd. It is a day to celebrate the wild animals around us and to teach people

why these animals are important. One great way to mark the day is to make your own nature documentary. To create this film, all you need is a camera and a subject. Here is how you can get started.

Pick a theme

First, decide what your nature documentary will be about. Would you like to film wildlife near your home? Or would you prefer to ask an adult to take you to a nearby park or a

nature reserve? Do some research and choose local wildlife that interests you. For example, think about animals living in your area and the ones you are most likely to see in the daytime. _______________

Once you have decided what to film, do more research on your subject. Take notes and look for interesting facts for your film. You can study the animals’ eating habits. You can also learn about physical differences between male and female animals of the same kind, from their size and colors to their behaviour.

Film and edit

You may use a video camera or your mobile phone to make your nature documentary. When you are ready to film, keep a safe and comfortable distance from wildlife. Do not get too close, or you may frighten your subject away.

You can also make an introduction. Put your camera in selfie mode. Introduce yourself and tell viewers why you chose this subject. Finally, you may use a free app to edit your film and add titles.

Host a screening

When you are happy with your film, invite your family and friends to watch it. You can hold a screening at home. You can also ask your local library if you can use one of its meeting rooms. After the screening, hold a question-and-answer session. Your audience can ask you questions about your documentary. At last, thank everyone for coming.

16. What is the purpose of making a nature documentary?

A. To improve skills of making films. B. To record qualities of wildlife.

C. To increase awareness of wild animals. D. To carry out a survey about wild animals.

17. Which of the following is the most suitable for _________

A. Do your research B. Share the film

C. Prepare a video camera D. Organize some activities

18. What should you pay attention to when you are ready for filming?

A. Having a talk with viewers. B. Inviting your friends to make notes.

C. Keeping a proper distance from wildlife. D. Making sure to use a camera to film better.
