Here I'd like to talk about how to develop your curiosity and make use of it to make discoveries. Asking questions is the first step to make discoveries and find interesting answers when you are curious about something and want to know more about it.

Firstly, write down the subject that you are interested in on a note card or piece of paper. Just put the main idea down, such as “Discover more about dinosaurs.”

Next, think for a moment about what you already know about your subject and list information like the sentences below：

1. Dinosaurs lived long before human beings appeared.

2. Dinosaurs lived on the earth for more than 150 million years.

3. Some dinosaurs fed on plants, some on meat.

Thirdly, ask yourself “What can I do with what I want to learn？” On your paper, start writing down questions about the dinosaurs as you think of them：

1. What's the best weather for dinosaurs to live in?

2. How many kinds of dinosaurs are there?

3. Have dinosaurs really disappeared?

Fourthly, armed_with_your_list_of_questions,_you can now visit the nearest library or turn to computer to begin your research. As you learn more about your subject, you'll probably discover some new questions.

For example, you might discover that dinosaurs disappeared about 65 million years ago. Why? What happened? Asking new questions can help you research your subject more deeply.

The next time you find something interesting to research, take time to organize your thinking by asking good questions. And remember—learning more always bring more questions.
