When you are curious about something and want to know more about it, you can use the way of asking questions. Asking questions is the first step to make discoveries and find interesting answers. The following steps can guide you during the research.
Step 1 Write down the subject that you are interested in on a piece of paper. Just get the main idea down. For example, you might write:
Discover more about robots.
Step 2 Stop and think for a moment about what you have already known about your subject. List what you have already known like the sentences below:
1. The first robot appeared in the USA in 1959.
2. A robot can do housework and act as a teacher.
3. Sometimes a robot catches viruses and causes a lot of problems.
Step 3 What can you do with what you want to learn? By asking questions, start writing down questions about the robots on the paper:
1. What might robots be like in the future?
2. What other things can robots do for people?
3. What kind of power will robots possibly use in five years?
Step 4 Armed with your list of questions, you can now go to the nearest library or 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 robots can help scientists explore dangerous places, like the sea and outer space. How? What happened? Asking new questions can help you research your subject more widely.
The next time you find something interesting to research, take time to organize your thinking by asking good questions. And remember that learning more always brings more questions.

Well, the terrible thing has already been done . Would you like to get down and play in the milk form a few minutes before we clean it up?”
Indeed, he did. After a few minutes , his mother said ,”You know , Robert , whenever you make a mess like this , you have to clean it up . We could use a sponge or a towel. Which do you prefer?” He chose the sponge and together they cleaned up the milk.
His mother. then said, “You know , what we have here is a failed experiment in how to carry a big milk bottle with two small hands .Let’s go out in the back yard and fill the bottle with water and see if you can discover a way to carry it without dropping it “  The little boy learned that if he held the bottle at the op near the lip(容器的嘴)with both hands, he could carry it without dropping it What a wonderful lesson!

You either have it, or you don’t-a sense of direction. But why is it that some people could find their way across the Sahara without a map while others can lose themselves in the next street?

Scientists say we’re all born with a sense of direction, but it is not properly understood how it works. One theory is that people with a good sense of direction have simply worked harder at developing it. Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it, we lose it.

“Children as young as seven have the ability to find their way around,” says Jim Martland, research director of the project. “However, if they are not allowed out alone or are taken everywhere by car, they never develop the skills.”

Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction. He makes the following suggestions:

If you are using a map, turn it so that it relates to(与……有联系) the way you are facing.

If you leave your bike in a strange place, put it near something like a big stone or a tree-something easy to recognize. Note landmarks on the route as you go away from your bike. When you return, go back along the same route.

Simplify(简化) the way for finding your direction by using lines such as streets in a town, streams, or wells in the countryside to guide you. Count your steps so that you know how far you have gone and note any landmarks such as towerblocks or hills which can help to find out where you are.

Now you will never get lost again!
