    You're rushing to work and a man ahead of you collapses (跌倒) on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people avert their gaze and keep on walking rather than stop and get involved. “There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into (进入) your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping.

    Why should I be the one? I'm probably not the most competent (有能力的) person in this crowd. You might think someone older or with more medical knowledge should offer assistance (帮助).

    What if he doesn't really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.

    No one else looks concerned-this must not be a problem. We can follow the people around us, but most  people tend to hold back their emotions in public.

     “If you spot (发现) trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don't have to take on the entire responsibility of being helpful. Sometimes it's just a matter of turning to the person next to you and saying, “It looks like we should do something.” Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you.”

    We often see top students around us and everyone knows about them. Let us take Jenny as an example. She is the monitor of our class. She spends a lot of time working for our class. But she always gets good grades in all subjects. How do students like Jenny do that? When I asked her, she said, "Hard work is not the whole story. It's not how long you sit at the desk with your books open. It's what you do as you are sitting." In fact, we can see many top students spend fewer hours on their studies than their classmates. Jenny gave me some valuable suggestions.

    If your math teacher gives you five problems, you should do six. If your Chinese teacher gives eight pages of reading, you should read nine. The more you practice, the more you learn.

    Studying is a matter of your personal interest, so choose the way you are most comfortable with. Some people like working at night when the house is quiet, while others like doing their work early in the morning. However, others like studying as soon asthey arrive home from school while the work is fresh in their minds. No matter which way suits you, try to do your best.

    Studying is your business and the business comes before entertainment(娱乐). When you are studying, phone calls should go unanswered, TV shows unwatched, snacks given up. Studying is the only thing in your mind. Nothing can pull your attention away from what you are studying.

    Studying is like eating. You should eat a little at a time. You can plan what to do today, but don't do too much. When you can't finish the work you planned to do, you will feel stressed and may lose confidence. On the other hand, you will not study well without a good plan. It all de pends on how you manage your time.

    The students who hand in a clearly written paper are already half way to get an A.. Tidy papers are likely to get higher marks than messy ones. When you write clearly and do your work carefully, the thoughts in your mind are clear. You can avoid making more mistakes.
