33. GWD21-Q33:

One of the limiting factors in human physical performance is the amount of oxygen that is absorbed by the muscles from the bloodstream.  Accordingly, entrepreneurs have begun selling at gymnasiums and health clubs bottles of drinking water, labeled “SuperOXY,” that has extra oxygen dissolved in the water.  Such water would be useless in improving physical performance, however, since the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs.

 

 

 

Which of the following, if true, would serve the same function in the argument as the statement in boldface?

 

 

 

1. the water lost in exercising can be replaced with ordinary tap water
2. the amount of oxygen in the blood of people who are exercising is already more than the muscle cells can absorb
3. world-class athletes turn in record performances without such water
4. frequent physical exercise increases the body’s ability to take in and use oxygen
5. lack of oxygen is not the only factor limiting human physical performance

答案是B,我就不知道这个HOWEVER,在这里是干什么的.我觉得前面一句说了喝这样的水没用,后面来了个however,就应该转折一下说...但是在什么方面有用才对.所以我选了D

请NN告诉告诉我

同不懂，帮顶～～～

虚心向牛牛们请教：）

这个HOWEVER应该是作者对前面商家想法的表示不同.意思是:商家认为这个水有用,但是,实际上是没有用的,因为.....

我觉得此处的HOWEVER和答案没有关系.

选项是要选个和黑体部分表述同样说明补充没有用的WEAKEN选项.

欢迎讨论!

however 在就中的位置是比较灵活的  你可以把他提到句首理解   文中说 水中的O 没用 之后since给了一个原因　　题目问有谁能替代ｓｉｎｃｅ　句　　就是说找一个支持结论　ｕｓｅｌｅｓｓ　的原因　　　B　很合适　　B说O　已经够了　　水中的没有机会起做用

我觉得这个however是应该跟前一句 however,Such water would be useless in improving physical performance,, since the only way to get oxygen into the bloodstream so that it can be absorbed by the muscles is through the lungs.

说明前面的让人喝有氧气的说没用

黑字部分翻译应该是，唯一方法是通过肺　其目的是让血液中的氧被肌肉吸收，我觉得这句的用途是支持前面的结论，而削弱那个广告，如果想b说的

1. the amount of oxygen in the blood of people who are exercising is already more than the muscle cells can absorb

血液中的氧气已经完全足够肌肉吸收的了，那在喝水也就没什么必要了（支持了结论，喝水没用）

我觉得d是个无关的选项，就算能提高身体的射入　和用氧气的能力　也不能说名喝水没用啊，可能喝水在原有提高的基础上还能提高呢　所以没办法支持结论

我不知道我说清楚没

however在句中用两个逗号隔开，经常是表示它所在的这句话（however前后两个部分作为整体）对前面一段话意思的转折，读起来很不符合中国人的语言习惯，但在GMAT各个部分里都很常见，只能适应

谢谢了，明白了。

关键是知道HOWEVER这里的位置到底是对哪个进行转折，题目就容易了。
