GWD 6 sloth bear

hopelanxyn

原文中说:根据黑熊和树熊的相似的运动速度和距离,推出如果小黑熊能跟的上大黑熊的话,那摸小树熊也能跟的上大树熊.

如果按D的话,黑熊的速度比树熊更快

那岂不是SUPPORT了.因为就算黑熊的速度比树熊快,小黑熊都能跟上大黑熊,那更说明了小树熊应该能跟的上大树熊呀!!

是啊，我同意这个观点。。这题到底选什么？？

假如灵活程度不一样，  if black bear cubs are able to keep up with their mother, so

too should sloth bear cubs.

so .... 就不一定成立了。

字这么大，哦, 不好意思。

以下是引用wangtsong在2007-12-16 1:16:00的发言：

字很大很清楚，理由也很清楚。明显就是D！

同篇这题。

为什么E项不对呢？文章中说了Sloth bears also have relatively large  canine teeth, which appear to be more  functional for fighting than for foraging.
    

Which of the following is mentioned in the passage as a way in which brown bears and sloth bears are similar?

 
                

1. They tend to become aggressive when provoked.
2. They live almost exclusively in treeless environments.
3. They are preyed upon by animals that can climb or topple trees.
4. They are inefficient in their locomotion.
5. They have relatively large canine teeth.

恩，同意10楼的观点，E是加强。various terrain应该更慢。

而D应该是直接削弱，说效率比较低，locomotion相当于slow travel rate吧？？

Furthermore, the daily movements (主语）of sloth (20) bears and American black bears （which are similar in size to sloth bears and have similar-sized home ranges）（Which引导的句子整个修饰Black bears) reveal （谓语）similar travel rates and distances(宾语）, 这道题最主要的是区分这句话的意思，我们把这句话的句子成分分解一下就可以明白要选的答案是(D)

程喷喷

原文强调的是黑熊和sloth在每天走的物理距离的相似性，由小熊能跟上推出小sloth能跟上。
如果E说的是sloth面对的terrain复杂多变的话，E是个完美的答案；可是这里是black bear，所以小熊面对的困难更大，所以E是加强而不是削弱；
D确实不像答案，但是唯一可选的：
至少它强调了二者不同，而且说了黑熊有其他优势；难道locomotion和efficient这些前面讨论plolar bear时内容真的是用来迷惑的？确实BT的题。

E？？  土地的类型可能不一样 ex. 棕熊在平地地 sloth bear在山地 －－－当然山地更累
