The flow chart provides an overview of the process about electricity production from geothermal energy, which shows how the cold water from being transformed to steam to generate electricity. Overall, the process is made up of five steps.

First, the cold water in a container from 4.5 kilometers high land is pumped down to the injection well, and then pass through a very long geothermal zone, which is made of hot rocks to warm up the cold water to hot water. The production well, which is connected to the geothermal zone, allow the hot water being pumped up to a big condenser which is a much bigger area than the container where the cold water stay. Here, in the condenser, steam can be generated from the hot water and go to the turbine by a small pipe. Finally, the steam makes the turbine work, and then the generator powered by the turbine can produces electricity.

To sum up, the process starts from cold water and ends up with electricity. It is a complex process.

There has been much debates about whether children should be allowed to make their own choices on everyday matters. From where I stand, I firmly believe that it is necessary to let children make decisions about matters that affect them.

Some people propose that allow children to make decisions about matters that affect them is very important. They have good point to support their view, and consider that children who good at make choices can do critical thinking well, which is a very important skill in their later studies and life. As we all know, critical thinking needs people to know the upside and downside of a thing, which is very necessary not only in their studies when they need to write essay, do research and so on, but also in their job choices like how to make career plan in thier life. Further more, if people can not make a proper career plan and researchers can not do critical thinking well, the country will face to the employment issue and the technology will not be improve fast.

Other people, however, believe that a society of individuals who only think about their own wishes will be formed, as a result of letting children to make their own choices on everyday matters. They have their arguments too, and think that this is because people are only consider their own benefits partially in spite of the whole societies. To be more specific, children who are permitted to make their own choices are probably only face the matter they meet, and they may become selfish adults by this thinking way. However, I think these people fail to realize that parents are needed to teach children how to make decisions, which are beneficial for whole societies.

In conclusion, considering that the issue can be solved, and allowing children to make their own choices performs more advantages, I strongly believe that it is important for children to make decisions about matters that affect them.
