A recent study shows that in fact, many dinosaurs might not have belo
6、nged to either category (类别) but instead have fallen somewhere in the middle. Warmblooded animals have bodies that are able to make their own heat. Their body temperatures stay about the same whether it is hot or cold outside. Coldblooded animals cannot make their own heat, so their body temperature
7、s depend on how warm the outside temperature is. Warmblooded animals have much more active lifestyles than coldblooded ones. When scientists first discovered the bones of ancient dinosaurs in the 1800s, they were sure the huge creatures must have been slow. But as scientists found more bones of smal
8、ler, quicker dinosaurs, like Velociraptor, they realized that the creatures may have been much more active than they had thought. A team of biologists began to examine. They knew that warmblooded animals grow faster than coldblooded ones. The researchers realized they could determine whether a dinos
9、aur had been warmblooded or coldblooded by finding its growth rate. The scientists examined the growth rings in bones from 21 different dinosaur species. The width of these growth rings showed how much the dinosaurs grew each year, much like the rings in a tree trunk (树干) do. “Our results showed tha
10、t dinosaurs had growth rates that were actually not characteristic of warmblooded or coldblooded animals，” said Brian Enquist, a scientist on the research team. “They did not act like mammals or birds, nor did they act like reptiles or fish. ” Instead, dinosaurs fell somewhere in between. Scientists
11、 call these middleoftheroad creatures “mesotherms”Being mesotherms gave dinosaurs several advantages. They were faster and stronger than reptiles that had to rely on the sun for warmth. Being somewhat coldblooded had its benefits too. Coldblooded animals burn energy more slowly. So they need much le

By being mesothermic，the dinosaurs could be both fast and big. 【解题导语】本文是说明文。研究表明恐龙既不是恒温动物也不是变温动物。1What is Paragraph 2 main

A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 025 dro
18、ps of water or juice as a reward. The researchers then tested how the monkeys combinedor addedthe symbols to get the reward. Heres how Harvard Medical School scientist Margaret Livingstone, who led the team, described the experiment: In their cages the monkeys were provided with touch screens. On on
19、e part of the screen, a symbol would appear, and on the other side two symbols inside a circle were shown. For example, the number 7 would flash on one side of the screen and the other end would have 9 and 8. If the monkeys touched the left side of the screen they would be rewarded with seven drops
20、of water or juice; if they went for the circle, they would be rewarded with the sum of the numbers17 in this example. After running hundreds of tests, the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, no
21、t just memorizing the value of each combination. When the team examined the results of the experiment more closely, they noticed that the monkeys tended to underestimate (低估) a sum compared with a single symbol when the two were close in valuesometimes choosing, for example, a 13 over the sum of 8 a
22、nd 6. The underestimation was systematic: When adding two numbers, the monkeys always paid attention to the larger of the two, and then added only a fraction (小部分) of the smaller number to it. “This indicates that there is a certain way quantity is represented in their brains，” Dr. Livingstone says.
23、 “But in this experiment what theyre doing is paying more attention to the big number than the little one. ”【解题导语】本文是一篇说明文。研究人员通过让三只恒河猴触摸屏幕两侧的不同数字(左侧为单个数字，右侧为圆圈内两个数字)对其进行研究，结果发现：猴子会算数。5What did the researchers do to the monkeys before testing them?AThey fed them.
