In the face of rising gas costs, many cons

题目内容：

In the face of rising gas costs, many consumers are beginning to consider the choice of a hybrid(混合动力的) vehicle--one which operates on both gas and electricity. All of the models of hybrid car will save money, but are they really effective when all of the costs of maintenance(维修) and other considerations are included in?

First of all, consider the cost of buying a hybrid vehicle. Depending on the model, hybrid vehicles can cost anywhere from $2,000 to $5,000 more than the traditional models. However, some say that as the hybrid cars become increasingly more available as a reflection of demand, the prices can be expected to drop, making them more cost effective when it comes to the initial investment(初始投资).

Also important to keep in mind is the fact that the hybrid cars have a much more specialized system than the standard vehicle, and will therefore require more specialized workers to repair them when they break down.

It seems as though, at least for the time being, the purchase of a hybrid vehicle for the average consumer may not be the best choice when it comes to saving money. It is important to keep several things in mind, however, when considering purchasing a hybrid model. Many consumers are choosing to purchase these cars because they represent a significant development in terms of environmental concerns over standard models. They also mean that as a whole, Western nations will become less dependent on oil as the only means of power.

Finally, it is necessary to remember that the hybrid car is a very new technology. Developed only within the last few years, the technology is still in the starting stage, where costs will continue to be high. As time passes, the development of the hybrid technology will begin to push prices down to the point where hybrids are more competitive with the traditionally fueled models of the past.
