把OG里所有的归纳题一起看了一下,发现自己好几道题目错在不理解题目本身.请叫各位NN给予指点:
175.Parasitic wasps lay their eggs directly into the eggs of various host incescts in exactly the right numbers for any suitable size of host egg. If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space. If too few effs were laid, portions of the host egg would decay, killing the wasp larvae.
Which of the following conclusions can properly be drawn from the information above?
(A): The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behaviors.
(B): Host insects lack any effective defenses against the form of predation practived by parasitic wasps.
(D):Failure to lay enough eggs would lead to the death of the developing wasp larvae more quickly that would laying too many eggs.

The answer is A.
对提干的理解大概是WASP把蛋下到别人的巢里.下的数目要正好.太少要死太多也要死.
对选项A也不理解.能否解释一下?
在没有理解A之前,我的选择在B和D之间.似乎他们都能从提干中推出来.

150. United States hospitals have traditionally relied primarily on revenues from paying patients to offset losses from unreimbursed care.
对150题的这句话不理解, 请叫!

145.Between 1975 and 1985, nursing-home occupancy rates averaged 87 percent of capacity, while admission rates remained constant, at any average of 95 admissions per 1000 beds per year. Between 1985 and 1988, however, occupancy rates rose to an average of 92 percent of capacity, while admission rates declined to 81 per 1000 beds per year.
If the statements above are true, which of the following conclusions can be most properly drawn?
(A)The average length of time nursing-home residents stayed in nursing homes increased between 1985 and 1988.
(C)Nursing home admission rates tend to decline whenever occupancy rates rise.

不知道这个admission rate 是什么?是不是收病人率?开始还没有想到这个,所以怎么也不认为A可能对.看看其他也只有C有点象.
能不能解释一下.

能不能请教NN们有没有什么好的思维方法做归纳提.我似乎对归纳题的思路有问题.在看钱永强的讲义里说,归纳没有什么特别的方法,只有排除法. 我以为就是提干里说到的才可以.我的理解是不是有问题. 以下是几道例题,请帮我分析以下:
123:Advertisement: Today's customers expect high quality. Every advance in the quality of manufactured products raises customer expectations. The company that is satisfied with the current quality of its products will soon find that its customers are not. At MegaCorp, meeting or exceeding customer expectations is our goal.
Which of the following must be true on the basis of the statements in the advertisement above?
(C)MegaCorp's goal is possible to meet only if continuing advances in product quality are possible.
(E)MegaCorp's customers are currently satisfied with the quality of its products.
用排除法当然把A,B,D都排除掉了.显然E就是提干的内容.而C要转一个弯挖出来的.所以我就选了E.其实答案是C.

115.Many people argue that tobacco advertising plays a crucial role in causing teen-agers to start or continue smoking. In Norway, however, where there has been a ban on tobacco advertising since 1975, smoking is at least as prevalent among teen-agers as it is in countries that do not ban such advertising.
Which of the following statements draws the most reliable conclusion from the information above?
(A) Tobacco advertising cannot be the only factor that affects the prevalence of smoking among teen-agers.
(B) Advertising does not play a role in causing teenaders to start or continue smoking.
一看到A是觉得A是正确的,但是看到B时觉得B更直接.所以选了B. 正确答案是A.

已经把OG和XDF的材料都做完了,发现还有不少问题.30号要考试了,我这下该怎么练呢?

拜托了,谢谢!

The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behaviors..是说可以根据wasp产卵的数目来决定宿主的卵的大小。因为提干中说了太少要死，太多也要死。因此必须正好。

D提干中没有说太多还是太少哪个更容易死。
B中说没有办法防卫也没有办法从文中推出。

对150题的这句话不理解, 请叫

题目中有个单词打错了吧？应该是rely吧？

这个题说收住率下降了，但是空床率却上升了，当然是说入主的人呆的时间长啊。

题目说了顾客期望高质量产品。即使顾客一时间满意，但是很快就不满意了，所以要满足顾客，只能不断提高产品。这个不就是C吗？

B完全否定广告对青少年吸烟的作用也是不对的。

以后你还是一道一道贴吧，我都快累死了。来来回回地贴。

归纳题是没有什么好办法的。如果你逻辑思维不强，只能靠理解题目。

Sorry, 美人鱼. 难得你那么尽心尽力.有机会一定请吃饭.
150. 已经改正了typing 的错误.

175: (A): The size of the smallest host egg that a wasp could theoretically parasitize can be determined from the wasp's egg-laying behaviors.
那么怎样来理解这个选项A呢?下的蛋的大小跟下蛋的行为有什么关系?难到还说它想下小蛋就下小吗?

总之,感激不尽.

宿主的蛋大小可以根据wasp下蛋的行为来决定，即题中提到的不能多也不能少。宿主的蛋大，w产卵的数目就多，反之就少。就是说按照比例来的。

150。美国医院传统上主要依靠来源于付费病人的收入来抵消免费治疗的损失。
