附件内容如下：
8.8 综合写作 tpo9
In the lecture, the professor points out that though hydrogen-based fuel-cell engines might be a replacement to internal-combustion engines with finite oil and the fact that burning oil will cause air pollution, the passage is too hasty to conclude that hydrogen-based fuel-cell engines will replace internal-combustion engines for reasons as followed.

Firstly, it's not so practical and available to obtain hydrogen. We can not obtain hydrogen directly from water, and on the other hand, it needs high technology to acquire the pure and liquid hydrogen, which is not practical now.

Secondly, air pollution problem cannot be solved even hydrogen replaces oil as the main power energy. Though the passage points out that the only byproduct of fuel-cell engines is water while the byproduct of internal-combustion engines is carbon dioxide, which will harm the environment, the obtaining process and liquefying process of hydrogen requires lots of energy from burning coal or other resources, which will also pollute the environment.

In addition, there will be no cost saving if the internal-combustion engines are replaced by fuel-cell engines due to the components of the fuel-cell engines need a very rare and expensive element, and till now, no cheaper material can be successfully replace that element, making the fuel-cell engines far more expensive than internal-combustion engines.
