上海环球托福春季班
   下面是环球教育老师为考生总结的关于托福TPO27解析,更多TPO信息请关注托福TPO频道。

1、从女生的语气中看出她想找一本书,但是没找到,所以请求library assistant 的帮助
 
2、Assistant: He’s a volcano expert so I thought he might be teaching your class.
这样答案就非常明显了。
 
3、据此推断,女生认为geology比assistant提到的三个科目都简单。
 
4、女生提到要查 Volcano Ruaephu,就是一个特定的火山,而非全部的新西兰火山
 
5、他说是2001年的资料,还有用么(Is that okay do you think?)assistant担心这个太老了。
 
Lecture-1
 
1、There are several techniques being employed tody that could prove useful ensuring the future of the reefs.
这就是lecture的topic sentence 根据他来确定选项。
 
 2、Coral is very sensitive to water temperature..........One future possibility is that improved monitoring can help predict when and where bleaching occur.
Monitor只提到了water temperature monitor,所以可以确定 第二句的monitor指的什么。
 
 3、教授的话中,出现了 could only be used as the last result, costly, even if it is successful, it still fails to address the ongoing problem.
      所以选项应该是负面的,最后一句与答案对应。
 
 4、这个东西 resistant to bleaching,与D项对应。 然后是 key points of overall resilience,那前面就是是解释这些refugia是关键的原因
 
 5、定位到 mangrove, 这属于一个例子,首先确定他是对 reef有益处的,mangrove roots have the ability to absorb and trap sediments of polluted water that flow through them before they enter the ocean. 这就是净化水源的作用
 
 6、在教授的例子中,这些都是 feed on organism that eat corals。 所以答案很明显They prevent a reef from growing by preying on young corals.
 
Lecture-2
 
 1、Tone quality differs from instrument to instrument. And the question is why. Why does an instrument sound more beautiful than another even if they look identical? Lecture的剩余部分全部是来解答这个问题,所以确定答案为C
 
 2、Today’s violin makers can pretty much replicate all the physical attributes of a Cremonese violin. Physical attributes 指的就是 craftsmanship。 而且从后文中也可以看出主要是木材的关系,与技艺无关。
 
 3、就是生长周期的不同导致了 density differential, 所以教授讨论生长周期就是在解释为什么有 density differential
 
4、对于古琴来说,办法是:turns out the Cremonese violins were made from trees that grew during a little ice age when temperature across Europe is significantly lower than normal. 也就是说 Cremonese 的木头是在小冰河期时候长出来的,全年气候都比较寒冷
 
5、He basically exposed the wood to a species of fungus, a mushroom........but this particular fungus nibbles away only at certain layers in the wood........as a result, the fungi treated wood approaches the woods of Cremonese wood.. 确定答案选择A
 
6、教授说大多数观众没注意到乐器的问题,女生说是的,她没留意。所以教授说这些话时为了证明这个观点是对的
 
 
Conversation-2
 
1、Student: would it be okay to focus on something related to agriculture?
很明显的,这就是讨论关于paper的topics
 
2、 Professor: Hydroponic.........is it a premodern technology?
   这是个反问句,教授的意思是他不是premodern
 
3、学生说文章说Aztec 发明了 hydroponics,教授就解释去证明后面的话: It appear to be hydroponics, but the plants draw nutrients from soil证明这种技艺不是水培。
 
4、Professor: It’s pretty common for a writer to generalize...用hydroponics去描述另一种技术,还说作者用这个词 casually,所以说教授认为这个并不十分准确。
 
5、Student: So I guess that all historians might not might describe Chinampas either.
Professor: Good point! Why not looking to that point too?
根据教授的why not,说明教授建议学生把这个也写进论文
 
 Lecture-3
 
教授说我们要讨论Sauropod,by comparing fossil records to modern animals 答案就在这两句中。
 
现在世界上最大的动物住在海里,海里食物比陆地上丰富,还有 but for an ocean-going whale, that’s not a problem. 说明陆地大型动物的一些困难可以在海里解决
 
However, we now know........there were much less plants for sauropods to eat than we thought.
注意转折词后面一般存在考点
 
前文中教授说 It is hard to maintain populations时提到的原因是:需要大量食物,生育率低和身体热量散失困难,所以选AB,D是维持,这个不对
 
Professor: We test hypothesis by looking for evidence to support them, then some questions are answered, that may lead to new questions. 然后就是gastroliths的例子,来证明这句话。讲完这个例子后还有 the original hypothesis, the stones was found as gastroliths, even though hasn’t been supported, has helped to make new hypothesis, which may eventually lead to the answer. 答案中的useful research指的即是这个
 
从上题的句子中推断,这些石头可能不是gastroliths
 
Lecture-4
 
文章讲了牛顿,歌德和Runge三个人的理论,说明中心就是 color theory的发展。
 
You’d better use a pure green. 说明用三原色混合的颜色不令人满意。因此对artist来说用处不大。
 
 
教授说牛顿并没有建立起完整地color theory,也没提到primary color,只是说给了一个客观地科学解释,所以说牛顿的例子算作背景信息,其它选项都没有提到。
 
And in terms of this goal, he wasn’t very successful.对应A选项
Scientist studying romantics and chromatics still marvel his studying. 对应C,对色学还是有一定贡献的。注意marvel的褒扬态度。
 
Runge’s choice of red, yellow, blue has nothing to do with what we know from modern day chromatics, it had to do with Runge’s complex system of symbolism. ....... Particularly with his experience of quality of lights at various times of the day.: morning noon and night. 与答案对应
 
 
He just happened ...at the same time of the same theory. 注意教授重读了happened,说明教授觉得这不一定是 happened。
