单选题Many doctors suspect that there may be some relationship between emotions and illness. However, they can not find a proof. It is until two decades ago when Louise Hay brings her books You Can Heal Your Body and You Can Heal Your Life to us, things get clear in our mind. In her book, over three hundred people were assessed in terms of their emotions for a two-week period. They were assessed for positive emotions they might be feeling, such as vigor, well-being, and calmness, as well as for negative emotions such as depression, anxiety, and hostility. Then they were each given a squirt in the nose of the virus that causes common cold. People with more positive emotional states were less likely to suffer from symptoms of the cold than people with negative emotional states and they restored to health in a short time. So there really does seem to be a link between emotional state and illness. According to her research, our emotions are fundamentally connected with all aspects of health. This belief is widely accepted by numerous medical workers. Some physical problems are linked to emotional well-being. Our body and emotion are dependent on each other for us to be healthy. Chinese traditional medical theories also hold the same idea that excitement does harm to the heart, anger to the liver, depression to the lung, and fears to the kidney. The immune system forms a solid protection to us. Whether or not we are likely to get disease depends on the work of our immune system. A person often feeling distressed may feel dizzy and develop heart disease, and the person feeling fearful is likely to get insomnia. Back pain has been attributed to a feeling of not being emotionally supported. Headache can be caused by a kind of strain from life and work. However, many of us must have experienced the miracle that the euphoria of a good day makes our ache go away. A positive person is more immune to the attack of diseases. Studies show that the system is in connection with our emotions. Therefore, emotions can be influential to one's mental and physical health. A happy patient with cancer may live longer than a depressed and disappointed patient. This is why many doctors help patients to release emotional strain besides the physical treatment. One should keep happy all the time. Only by this way, one can make his life better and healthier.

单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the US had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone. Today Mars looms as humanity's next great terra incognita. And with doubtful prospects for a short- term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is-clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science. which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those experiments pro- vide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life, If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
