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 and 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 fuels a sense of hopelessness and discourages then from making efforts to build a safer world.

In our interconnected world, the lack of agreement in and out 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 untied efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

       C．Science is getting dangerously out of control.

       D．Science is used for both good and bad purposes.

2．According to the passage, what will happen if we hold that science is getting beyond control?

       A．The development of science will hopelessly slow down.

       B．Businesses will have even greater influence on science.

       C．The public will lose faith in bringing about a bright future.

       D．People will work more actively to put science under control.

3．The discussion should reach beyond scientific societies because ________.

       A．scientists have failed to predict the outcomes

       B．the ties between different areas need strengthening

       C．united efforts are necessary for the development of science

       D．people need to work together to prevent the bad use of science

4．What is the main idea of the passage?

       A．Science and its applications bring us many dangers.

       B．The development of science mostly lies in people’s attitudes.

       C．Mankind can largely take control of science with their efforts.

       D．The future of science will be influenced by the dangerous ideas.

Death Valley, one of America’s great national parks, is a place of strange and silent beauty. As beautiful as this place is, its name provides evidence of very real danger. Death Valley is a land of beautiful yet dangerous extremes. There are mountains that reach more than 3,000 meters into the sky. There is a place called Badwater that is the lowest area of land in the Western Hemisphere. If there were water there, it would be 86 meters below the level of the ocean.
Death Valley can be dangerously cold during the winter months. Storms in the mountains can produce sudden flooding on the floor of the Valley. The air temperature during the summer has been as high as 57℃. The sun can heat the ground so that the temperature of the rocks and soil can be as high as 74℃. The extreme heat of Death Valley has killed people in the past. It will continue to kill those who do not honor this extreme climate. Death Valley does not forgive those who are not careful.
Death Valley is a good example of the violence of nature. It contains evidence of several ancient volcanoes that caused huge explosions. Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide.
In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black. Other areas of rock look as if some huge creature violently broke and twisted the Earth to create unusual, sometimes frightening shapes.
In other parts of Death Valley there are lines in the rock that show clearly that this area was deep under an ocean for many thousands of years. Much of the Valley is flat and extremely dry. In fact, scientists believe it is the driest place in the United States.
Death Valley, part of the Great Mojave Desert, is a huge place. It extends more than 225 kilometers across the southern part of California, and across the border with Nevada.
