There is a photo hanging above my desk. Whenever I look at that photograph, it takes me back to those early years every new experience was important for me.

I can still remember the shouts of the spectators as I (go) out onto the sports field with my classmates. Two (early). I had qualified for the finals of the 100 metres. Now (look) around, I was determined to win.

While I was walking across to the start, I began to feel more and more nervous. I looked around and saw my proud parents waving enthusiastically. My heart was beating fast when I lined up with the other eager competitors. I look some deep breaths and waited for the signal. Then the starting signal (give) and I set off down the track.

I ran as fast as I could, not looking at anything but the finishing line. By the time I crossed the line, I was so exhausted that I hardly breathe. As soon as I heard the result (announce), I realized I had won! Overjoyed, I collapsed on the soft grass with a broad smile on my face.

“Well done!” said the Headmaster later, as I was presented with the winner’s certificate. I had never felt so happy and proud in my life.

One of the first questions young children ask is “Why?” It is human nature to want (find) out why things are the way they are. You can find out “Why” by turning the question into a hypothesis (假设) for experiment.

example, suppose you have been trying to grow tomato plants, but insects keep destroying (put) large strips of colored cloth around the plants will keep insects away. Your question might be “Do certain colours of cloth keep insects away?” Then you’d begin your experiment. The first step would be to place different-colored strips of cloth around all of the plants except one. Then, as regular intervals, you would observe and record and note the plant had any insect damage or not.

This experiment may prove that the answer to your question is “No, it is not different-colored strips of cloth keep away insects.” Or you may find that answer is “Yes, certain insects are kept away by blue cloth, but not yellow cloth.” ...... you have found, you are well on your way to understanding how you can use scientific thinking to solve a problem in you own life.
