做了TPO19阅读的来讨论下吧，第三篇Ice Age一道题
第24题，答案是选B，不明白，为什么呢？氧16含量高不是说明没有什么蒸发，应该是气温比较低的时候吧，为什么是extensive glaciation没有发生的时候呢？

我开始选的是D。

其实这题我也错了，但仔细看后，我觉得应该是“as snow to form glacial”指明了方向，随后文章就提到了During glaciations(冻结成冰)，以及结冰的过程先evaporation再 is precipitated, 所以应该是extensive glaciation was not occurring:)

tpo6的第二篇十九题
答案选择B
C/D选项明显是错误 B选项我觉得不对啊 文中没有提及hear told啊 A选项也不知道是哪里错了 希望可以给我解释一下 谢谢
原文◆ Three other explanations seem more promising. One involves physiological changes relevant to memory. Maturation of the frontal lobes of the brain continues throughout early childhood, and this part of the brain may be critical for remembering particular episodes in ways that can be retrieved later. Demonstrations of infants’ and toddlers’ long-term memory have involved their repeating motor activities that they had seen or done earlier, such as reaching in the dark for objects, putting a bottle in a doll's mouth, or pulling apart two pieces of a toy. The brain's level of physiological maturation may support these types of memories, but not ones requiring explicit verbal descriptions.
题目
What does paragraph 3 suggest about long-term memory in children?
A Maturation of the frontal lobes of the brain is important for the long-term memory of motor activities but not verbal descriptions
B young children may form long-term memories of actions they see earlier than of things they hear or are told

能帮我解释一下，TP016的第一篇最后主旨题吗？我选的是Quality，stability和revenue。。。

Paragraph 6 The key factor in the success of thesecountries (along with high literacy, which contributed to it) was their abilityto adapt to the international division of labor determined by the earlyindustrializers and to stake out areas of specialization in internationalmarkets for which they were especially well suited.
This meant a great dependence oninternational commerce, which had notorious fluctuations;but it also meant high returns to those factors of production that werefortunate enough to be well placed in times of prosperity. In Sweden exports accounted for 18percent of the national income in 1870, and in 1913, 22 percent of a muchlarger national income. In the early twentieth century, Denmark exported 63 percent of itsagricultural production: butter, pork products, and eggs. It exported 80percent of its butter, almost all to Great Britain, where it accountedfor 40 percent of British butter imports.

10.Which of the sentences below best expresses the essential information in thehighlighted sentence in the passage? Incorrect choices change the meaning inimportant ways or leave out essential information

○The early industrializes controlled most of theinternational economy, leaving these countries to stake out new areas ofspecialization along the margins.
○Aided by their high literacy ratesthese countries were able to claim key areas of specialization withinestablished international markets.
○High literacy rates enabled thesecountries to take over international markets and adapt the internationaldivision of labor to suit their strengths.
○The international division of labor established bythe early industrializes was well suited to these countries, a key factor intheir success.

为什么第三个不对，第二个对？

TPO 八套的第一篇文章：
   The city of Teotihuacán, which lay about 50 kilometers northeast of modem-day Mexico City, began its growth by 200 -100 B.C. At its height（顶峰） between about AD. 150 and 700, it probably had a population of more than 125,000 people and covered at least 20 square kilometers. It had over 2,000 apartment complexes（场所，集合体）, a great market, a large number of industrial workshops, an administrative center, a number of massive religious edifices（宏伟的建筑物，如教堂）, and a regular grid （规则的方格）pattern of streets and buildings. Clearly, much planning and central control were involved in the expansion and ordering of this great metropolis（大都市）. Moreover, the city had economic and perhaps religious contacts with most parts of Mesoamerica (modern Central America and Mexico).
红色的部分是什么意思呢？麻烦大家了！

fobiUID: 3046182

Among the main factors are Teotihuacán's geographic location on a natural trade route to the south and east of the Valley of Mexico, the obsidian resources in the Teotihuacán Valley itself, and the valley’s potential for extensive （广阔的，大量地） irrigation.
接上楼，还有这个红色的句子是什么意思？尤其是“to the south and east”？

Weather Forecasters

Throughout history, various people have demonstrated a high degree of confidence in the ability of certain animals to predict the weather. It may seem surprising today in view of the complex equipment now involved in weather forecasting to understand that in certain cases, the behavior of animals does indeed provide an indication of imminent inclement weather. Sensitivity of certain animals to falling air pressure or to low-frequency sound waves that humans cannot hear, which are indicators of approaching storms, causes behaviors in animals that certain societies have come to recognize as predictors of storms.
  
  A number of animals are remarkably sensitive to variations in air pressure, and some of these animals exhibit consistent, noticeable, and predictable behaviors as air pressure drops before a storm hits. Where the air pressure drops before a storm, some animals move closer to the ground to equalize the pressure in their ears: some birds such as swallows tend to stay on the ground or roost in trees instead of soaring in the skies when a storm is imminent because of the decreasing air pressure. Other animals make more noise than usual as air pressure drops: an unusual amount of quacking by ducks and a high volume of croaking by frogs are both indicators that are believed to occur because of the high degree of sensitivity of ducks and frogs to the change in pressure. Finally, still other animals become more active before storms as a reaction to the falling air pressure: dolphins and porpoises seem to be taking part in a frenzied sort of play, and bees and ants become more active prior to storms, most likely because of their sensitivity to lower pressure.

Paragraph 2：Further evidence for the costs of begging comes from a study of differences in the begging calls of warbler species that nest on the ground versus those that nest in the relative safety of trees. The young of ground-nesting warblers produce begging cheeps of higher frequencies than do their tree-nesting relatives. These higher-frequency sounds do not travel as far, and so may better conceal the individuals producing them, who are especially vulnerable to predators in their ground nests. David Haskell created artificial nests with clay eggs and placed them on the ground beside a tape recorder that played the begging calls of either tree-nesting or of ground-nesting warblers. The eggs “advertised” by the tree-nesters' begging calls were found bitten significantly more often than the eggs associated with the ground-nesters' calls.

4. Paragraph 2 indicates that the begging calls of tree nesting warblers

○ put them at more risk than ground-nesting warblers experience

○ can be heard from a greater distance than those of ground-nesting warblers

○ are more likely to conceal the signaler than those of ground-nesting warblers

○ have higher frequencies than those of ground nesting warblers

这道题选B。比较迷糊的一点就是不知道A如何排除
这个选项的意思指的是在树上筑巢的鸟的叫声把它们放在一个相对危险的地位，而文章表达的意思是那些在树上筑的巢相对安全，是不是这么个微妙的区别。
