　　对立观点：

　　In this modern society, people always confront the dilemma of choosing whether AAA or BBB. This problem is a much debated one in that it affects everybody in his or her daily life. People may prefer one to the other although some may have no opinions about either at all. Before rendering my opinion, I think it is necessary to take a glance at the arguments on both sides.

　　It is quite rational for average people to choose BBB because of the obvious reason that 原因.The most extreme manifestation of this idea is the fact that 例子.Even so, however, many advantages of BBB over AAA will be obscured by its considerable drawbacks such as 例子.Therefore we have no complete evidence to suggest that BBB is always better than AAA. Moreover, a close scrutiny of the potential benefits of choosing AAA would reveal how flimsy it is to stick to the propensity to BBB over AAA.

　　There are numerous reasons for my preference for AAA, and I shall here explore only a few of the most important ones. One chief reason is that 原因一.And I can think of no better illustration of the idea than the fact that 例子一. The above is only part of the important aspects, and another one with equal significance with respect to choosing between the two lies in the development of the proposition that 原因二. This well explains the undeniable fact that 例子二. Besides, a further reason why I advocate AAA is that 原因三.This may explain why 例子三.

　　Last but not least, there is also a more practical reason why I would choose AAA, that is 原因四.

　　All in all, taking into account all these merits that AAA boasts of, we may safely arrive at the conclusion that the advantages of AAA outweigh any benefit we can get from BBB and choosing AAA is a rather wise decision.
