练习一下里面示范的TPO22
【范文】
The lecture focuses on convincing people that ethanol will become a good
alternative for gasoline in the future.
First, it seems specious to the lecturer that the increasing use of ethanol will add
to global warming. Though carbon dioxide will be released into the atmosphere
when we use ethanol as our fuel. In fact, we produce ethanol from plants, such
as corn. As a result, every plant we grow for ethanol absorbs carbon dioxide
from the atmosphere as part of its nutrition. That is to say, the growing of plants
counteracts the release of carbon dioxide.
In addition, we need never to worry about the reduce of animals' food due to the
use of ethanol. Based on research, it proves that ethanol is produced from one
part of a plant that is not eaten by animals. It is true that we have to produce
ethanol from plants, but only a specific part is required. Moreover, such a part of
plants will not be favored as food for animals. So conclusion can be drawn that
the number of animals' food will not be influenced by production of ethanol.
Finally, the professor argues that ethanol will have a good chance to compete
with fossil fuels on price in the near future. During this process, government
subsidy plays a significant role in making ethanol cheaper than usual. Besides,
as the market becomes more mature, more ethanol is bought and produced.
The increase of production will surely lead to a drop on price. According to some
calculation, once the production triples, the price of ethanol will decrease by 40
per cent. Ethanol seems promising in competing with fossil fuels since it will
become much cheaper in the future.
From the three points discussed by the professor, we could clearly learn that the
use and production will not add to global warming, reduce the food source of
animals, but can make ethanol such a prospective energy source. so ethanol will
become an excellent alternative for gasoline.

The lecturer claimed that ethanol fuel can be a good alternative to gasoline, and the three reason mentioned in the reading material are not convincing at all.
Firstly, even thought burning ethanol do release carbon dioxide, but the plants that ethanol are made from actually absorbed a huge amount of carbon dioxide while their growth, which counteracts the amount ethanol released, thus using ethanol will add up the global warming process as the reading material asserted.
In addition, ethanols are produced by the cell wall of the plants, the part of the plants that are not eaten by the animals. In that case, the food source for animals will not decrease like what was described in the reading material.
Finally, if only there are enough people use ethanol as fuel in the future,the production of ethanol will be largely increased, which will lead to a huge drop down of the price,making the price of the ethanol competitive with the price of gasoline.
