A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.  

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.  

Some people go even further. They say that despite the moral and legal objections （反对）, whatever is scientifically possible will be done ――somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.  

In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact （影响） on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.  

Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

How to Be a Winner

Sir Steven Redgrave  

Winner of 5 Olympic Gold Medals  

“In 1997 I was found to have developed diabetes （糖尿病） . Believing my career （职业生涯）was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it----the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn’t finished yet. Nothing is to stand in my way.”  

Karen Pickering  

Swimming World Champion  

“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success―you can’t follow a career in any field without being well-organized. List what you believe you can achieve. “Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”  

Kirsten Best  

Poet ＆ Writer  

“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological （心理的） tool.”
