我怎么觉得答案应该是c啊

35According to the passage, until recently zoologists believed which of the following about all phocids mothers?

1. Their fasting periods after giving birth were typically shorter than those of otariids.

2. Their lactation periods were generally as long as those of comparably sized otariids.

3. They acquired only moderate energy stores in the form of blubber before arriving at breeding sites.

4. They depleted less than a third of their stored body fat during lactation.

5. The replenished their fat stores only after their lactation period ended.

 

Zoologists had assumed that
            females of all phocids species, by contrast,
            use a fasting strategy in which mother
            phocids, having accumulated large energy
            stores before they arrive at breeding sites,
            fast throughout the entire lactation period, which lasts from 4 to 50 days depending on
            the species.

 

However, recent studies on
            harbor seals, a phocids species, found that
            lactating females commenced foraging
            approximately 6 days after giving birth and
            on average made 7 foraging trips during
            the remainder of their 24-day lactation
            period.

Zoologist最近才相信，所以应该是however开头的那一句话才是，明显的对比就是储存的energy不足才会最近发现6天后就要去寻找食物，因该是这样子才对吧！？

以下是引用xealot在2004-12-21 18:21:00的发言：

The article has two major points:

1. The recent finding, line 1 to line 29

2. The explanation to the finding, line 30 to the end(line 56)

So the two topics are well balanced, and thus in question 34, answer D is perferable to A.

According to line 1 to line 23 of the article, the major difference between the two type of animals is whether they feed during their lactation. This is why we choose E in regards of quesiton 35. The A in quesiton 35 kind of beats about the bush and thus is somehow away from the point. Besides, the respective fasting periods are 5 to 11 days and 4 to 50 days -- that is-- we cannot assert that one is longer/shorter than the other.

Regarding question 36, we cannot quickly rule out the option B as the example here is actually not a TYPICAL one. To support the conclusion the maternal strategy of such seal is related to the size of body, the author raises the example in which the similarly sized animal is mentioned and juxtaposes the two species of animals.

And, I suggest read the article comprehensively enough and try to grasp what the author WANTS to manifest. Just feel free to post any further concerns here. Wish this helps.

35题同意(荧光标注部分)

But,让我们回到33题,大家不觉得这两个题目的答案自相矛盾吗?

33,35题,考点都在原文第一段

既然"the major difference between the two type of animals is whether they feed during their lactation."

那么33题应该选D呀

请高人指点

It can be inferred from the passage that the females of all phocids species differ from the females of all otariid species in that the female phocids

1. have shorter lactation periods

2. consume more food during lactation

3. consume a higher proportion of fat stores

4. forage for food occasionally during their lactation periods

5. deplete a smaller percentage of their fat stores during their lactation periods

我想D错在occasionally，O不是occasionally这样做，而是在lactation periods都要这样做，不然会挂的哈哈

A很明显原文已经给出了O和P的lactation时间对比

"35题是ets狡猾的地方，狡猾就狡猾在这个until recently上了，如果说是before,traditional等等就比较明白是取非题了，

这个题目的答案在L23however, recent studies开始说的内容，取非就可了，

我原来也选了A但A不对因为原文并没有明确指出两者天数的比较，5-11和4-50我觉得也没法比"

为什么取非，其实however后面的不就是说时间的长短吗？

我比較有問題的是Q33,Q34 and Q36????

 

Q33 It can be inferred from the passage that the females of all phocids species differ from the females of all otariid species in that the female phocids

1. have shorter lactation periods

2. consume more food during lactation

3. consume a higher proportion of fat stores

4. forage for food occasionally during their lactation periods

5. deplete a smaller percentage of their fat stores during their lactation periods

ANS: A

雖然我也支持A選,因為O的哺乳期長達四個月到三年,而P則4-50天很明顯P比O短

但想請教一下C選,文章有提到P的另外一種物種叫harbor,

它們在哺乳期時deplete large proportion of their fat stores.

雖然文章看不出它們有higher than O,但C選真的很想選又不敢選????

 

Q34: The primary purpose of the passage is to

A. present evidence that several phocid species use the maternal fasting strategy

B. explain why the maternal strategy typically used by phocids is different from the maternal strategy used by otariids

C. argue that zoologists’ current understanding of harbor seals’ maternal strategy is incorrect

D. describe an unexpected behavior observed in harbor seals and propose an explanation that may account for that behavior

E. describe evidence concerning the maternal strategy of the harbor seal and suggest that the harbor seal belongs to the otariid rather than to the phocid family

ANS D

我選:B,原以為D選只是文章一小部份,整篇文章感覺在比較phocids以及otariids之間採用不同的strategy,並且對它們的行為上的描述,對於d選還是想不通為何是d…

Q35: According to the passage, until recently zoologists believed which of the following about all phocid mothers?

A. Their fasting periods
                after giving birth were typically shorter than those of otariids.

O→5~11天(...and the fast for 5 to 11 days after birth.); P(=h)→6天(approximately 6 days giving birth…),所以,沒差!!!!

B. Their lactation periods were generally as long as those of comparably sized otariids.

O and P的哺乳期很明顯不同並沒有一樣長

C. They acquired only moderate energy stores in the form of blubber before arriving at breeding sites.

這在講O並非題目要求的P

D. They depleted less than a third of their stored body fat during lactation.

Less錯應改成large

E. The replenished their fat stores only after their lactation period ended.

However, recent studies….那段有提到h(類P)結束哺乳期後6天才開始Forage,因此E, correct

ANS E

Q36: The author of the passage mentions ringed seals most probably in order to

A. provide an example of a phocid species that fasts throughout its entire lactation period

B. provide an example of a phocid species whose maternal strategy is typical of phocid species

C. provide an example of a phocid species that may deplete an even higher proportion of its fat stores during lactation than harbor seals do

D. support the assertion that harbor seals are smaller than many other phocids

E. support the assertion that harbor seals’ maternal strategy may be related to their small size

 

ANS E

這題雖然選對,但因為其它選項都不好於是才勉強選E,我對文章中提出R的用意其實不是很理解,

只知道R和H一樣small size,並且採用foraging strategy.不知道如何在回文定位中可以看出,它們

體型小脂肪少所以需要出去foraging????
