How a Solar Hot Water System Works

The first step is to capture solar radiation. That is, the sun’s energy must be absorbed by a solar heat collector, which is usually built in a southfacing roof. The collector has several layers of material. It has a glass plate and a metal absorber plate, which is painted black to increase its ability to absorb heat. Next to the absorber plate are copper tubes, which are filled with transfer fluid. The tubes are surrounded by foam insulation(隔离) and aluminum casing to help hold the heat in them. The process of trapping the sun’s radiation is as follows. As the sun shines through the glass plate, its thermal energy is absorbed by the copper absorber plate. This heat is conducted from the plate to the tubes. The heat from the tubes is then conducted to the fluid flowing through them.

After trapping heat from the sun, the second step is to transfer this heat to water which is stored in an insulated tank. The hot fluid from the collector is circulated by a pump through copper coils inside the tank. The heat is conducted by the coils to the water. When the supply of solar radiation is reduced on cloudy days, an auxiliary system can take over.

Dispensing(调配) the hot water is the final step in the process. The water flows from the outlet valve(阀) through pipes to faucets throughout the house.

In summary, the process of collecting and converting solar energy for use in a solar hot water system involves three steps. First, collectors absorb the sun’s energy, which is then transferred to fluid in copper tubes. These tubes run from the collector to a tank, where the water is heated and stored. Finally, the hot water is distributed through pipes to wherever it is needed. Although initially expensive to install, solar heating systems are economical in the long run —— at least until utility companies figure out how to charge us for sunshine!

Task Ⅱ. Write an outline (20%)

Directions: Read the following passage carefully and try to compose an outline for the passage provided.

Nowadays, television sets have become standard pieces of equipment in most homes, and watching television has become a standard activity for most families. Children in modern society grow watching television in the morning, in the afternoon, and often in the evening as well. Although there are many excellent programs for children, many people feel that television may not be good for children. In fact, television may be a bad influence on children for three main reasons.

First of all, some programs are not good for children to see. For example, there are many police stories on television. People are killed with guns, knives, and even cars. Some children might think that these things could happen to them at any time. Therefore, they can become frightened. In addition, some youngsters might begin to think that violence is a normal part of life because they see it often on television. They may begin to act out the violence they see and hurt themselves or their playmates.

Second, television can affect children’s reading ability. Reading requires skills and brain process that watching TV does not. If children watch television too many hours a day, they don’t practice the skills they need to learn how to read.

Finally, television may affect children’s school work in other ways. If they spend too much time watching television, they may get behind in their homework. Also if they stay up to watch a late movie, they may fall asleep in class the next day. Consequently, they will not learn their lessons, and even fail in school.

In summary, if children watch too much television or watch the wrong programs, their personalities can be harmed; furthermore, their progress in school can be affected. Therefore, parents should know what programs their children are watching. They should also turn off the television so that their children will study.

Task Ⅲ. Composition (60%)

Directions: Write a narrative (in 250 words) as required: Tell about one event that caused you the greatest guilt(内疚) and the way you handled(处理)it.
