发现(discovery)
    discovery is not such a big and noble word that only experts and scientists are entitled to use. in fact, every one of us makes discoveries as we grow. for example, a baby will find out how he can play with his toy car after he has tried several times. we will discover how to ride a bike skillfully after practicing again and again. often a discovery brings great joy to the person who makes it. you will certainly be delighted when you find the thing you have been looking for. you will be extremely happy when you one day realize that you have learned and mastered a skill or method which was almost too difficult for you at the beginning. sometimes, however, discovery means regret or even pain. you witt feet great regret when you find that you have hurt one of your friends or one of your family members. you will surely be disappointed when you discover that you failed in the examination for which you have prepared for a tong time. joy or sorrow as it may bring, discovery is an integral part of our life.
