Animals need natural periodic signals like sunrise to maintain a cycle whose period is precisely 24 hours. ■Such an external cue not only coordinates an animal's daily rhythms with particular features of the local solar day but also—because it normally does so day after day-seems to keep the internal clock's period close to that of Earth's rotation. 11. The word it in the passage refers to ○ an external cue such as sunrise ○ the daily rhythm of an animal ○ the local solar day ○ a cycle whose period is precisely 24 hours 这道题怎么能快速选出是A呢 |

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.. [; E; C/ H) z+ g, G

tpo14第二篇第一道
understand the ancient Mayan people who lived in the area that is today southern Mexico and Central America and the ecological difficulties they faced, one must first consider their environment, which we think of as “jungle” or “tropical rainforest.” ■This view is inaccurate, and the reason proves to be important. ■Properly speaking, tropical rainforests grow in high-rainfall equatorial areas that sixteen hundred kilometers from the equator, at latitudes 17 to 22 degrees north, in a habitat termed a “seasonal tropical forest.” ■That is, while there does tend to be a rainy “season from May to October, there is also a dry season from January through April. If one focuses on the wet months, one calls the Maya homeland a “seasonal tropical forest“; if one focuses on the dry months, one could instead describe it as a “seasonal desert” ■
1 Why does the author call Mayan homeland both a “seasonal tropical forested” and seasonal desert?
1 To illustrate how the climate of the Mayan homeland varied from region to region.
2 To explain how the climate of the Mayan homeland is similar to that of a jungle or tropical
3 To emphasize the vast size of the area that comprised the Mayan homeland in ancient times5
4 To make the point that the Mayan homeland is climatically more complex than is generally assumed

Advertisers sometimes offset or counterbalance an exaggerated claim with a disclaimer-a qualification or condition on the claim. For example, the claim that breakfast cereal has a health benefit may be accompanied by the disclaimer "when part of a nutritionally balanced breakfast." However, research has shown that children often have difficulty understanding disclaimers: children may interpret the phrase "when part of a nutritionally balanced breakfast" to mean that the cereal is required as a necessary part of a balanced breakfast. The author George Comstock suggested that less than a quarter of children between the ages of six and eight years old understood standard disclaimers used in many toy advertisements and that disclaimers are more readily comprehended when presented in both audio and visual formats. Nevertheless, disclaimers are mainly presented in audio format only.
我想问下,这个里面的disclaimer是什么意思呢
下面这个是TOP10 Seventeenth-Century European Economic Growth
Paragraph 7:Bills of exchange contributed to the development of banks, as exchangers began to provide loans.

The Geologic History of the Mediterranean
Paragraph 3 Withquestion such as these clearly before them, the scientists aboard the GlomarChallenger processed to the Mediterranean to search for the answers. On August23, 1970, they recovered a sample. The sample consisted of pebbles of gypsumand fragments of volcanic rock. Not a single pebble was found that might haveindicated that the pebbles came from the nearby continent. In thedays following, samples of solid gypsum were repeatedly brought on deck asdrilling operations penetrated the seafloor. Furthermore, the gypsum was foundto possess peculiarities of composition and structure that suggested it hadformed on desert flats. Sediment above and below the gypsum layer containedtiny marine fossils, indicating open-ocean conditions. As they drilled into thecentral and deepest part of the Mediterranean basin, the scientists took solid,shiny, crystalline salt from the core barrel. Interbedded with the salt werethin layers of what appeared to be windblown silt.
3.What does the author imply by saying “Not a single pebble was found that might have indicated that the pebbles came from the nearby continent”?
○The most obvious explanation for the origin of the pebbles was not supported by the evidence.
○The geologists did not find as many pebbles as they expected
○The geologists were looking for a particular kind of pebble."
○The different pebbles could not have come from only one source.
答案是A,其实我选的也是A,但是想问一下这句话的准确翻译是什么?为什么要选A呢?谢谢!
