【简答题】
When I come across a good essay in the newspaper, I often cut it and keep it. But just as I am about to do so, I find the article on the opposite side of the page is as much interesting. It may be a discussion about a way to keep in good health, or advice about how to behave and conduct oneself in society. If I cut the front essay, the other one on the back of the page will suffer damage, leaving out half of it or the text will be kept but missing the subject. As a result, my scissors would stop before they start, or only halfway done when I find out the regrettable consequence. Sometimes, two things are to be done at the same time, both deserving your attention. You can only take up one of them — the other has to wait or even be given up. But you know the future is unknown — the changed situation may not allow you to do what is left behind. Thus, you are caught in a fix and you may feel sad. How come that nice opportunities and brilliant ideas should gather around all at once? It may happen that your life changes dramatically on your preference of one alternative over the other. In fact, that is what life is like: we are often faced with two choices that are equally desirable, just like what happens during newspaper cutting. It often occurs that our attention is drawn to one thing only after we are engaged in another. The latter may be more important than the former and thus giving rise to a divided mind. I still remember a philosopher’s remarks: “When one door shuts, another one opens in life .” So a casual or passive choice may not necessarily be a bad one. Whatever we do in our lifetime, wherever life’s storm tosses(抛)us, there must be something we can achieve, some shore we can land on that opens up new vistas(景色)for us. Don’t forget there is always an alternative door open for everyone. While the first door is closed, there must be another that is open for you.
