3.选A还是选B的确是一个热门话题，我们来研究一下，二者各有优势，不过我来选的话，A的优点还是比B多。

第一段前两句同2，第三句

While both the two [methods/choices] may he their advantages and disadvantages, they can be applied under different circumstances. Later on, I will explain my opinion about it.

第二段：[A has the obvious advantage that / One very strong argument for A is that] ____________. But there lies intrinsic harmful characteristic in this method. Some [people/experts] [maintain/warn] that____________ Furthermore, ____________. Therefore we he no plete evidence to suggest that A is always better than B.

第三段：On the other hand, choosing B also has advantages to some extent, For example, ____________. However, once again, it is important to see that under certain circumstances B will____________(disadvantage)或：Yet there are some people who cast serious doubts on B或：Although B does he its seemingly profound [advantages/ reason],in the meantime[there lie intrinsic [harmful characteristics/drawbacks] in it such as ________________________ / it can be achieved only conditionally because____________].

第四段：(针对我个人的情况又可以说出一套理由)But if all these factors are contemplated, [as far as I am concerned / according to my knowledge], the advantages of A carry more weight than those of B because A fits [me/us students] better in two ways: In the first place, ____________, In the second place/secondly,____________Therefore from what we he discussed, we may safely e to the conclusion that choosing A is a rather wise decision.或：(我个人的情况说不出什么新的理由，只好说我觉得A优点就是比B多)

It seems very difficult for us to prefer one to another because all of them he their advantages and disadvantages to the extent that it is hard to distinguish. Yet that does not mean that they are all the same to me. Which one I prefer depends on my own experience, life style and [emotional concerns / educational background/____________]. [As far as I am concerned / According to my personality and fondness/ To be frank], I would like to choose A, because there are too many benefits that outnumber its disadvantages not to choose it. B, on the other hand, has advantages no more than its disadvantages.
