A recent study shows that in fact, many dinosaurs might not have belonged 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 temperatures 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 smaller, 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 dinosaur 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 that 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 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 less food to live than warmblooded animals. “It is doubtful that a lion the size of Trex could eat enough to survive，” explains John Grady, another biologist on the research team. 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 mainly about?AThe advantages of coldblooded animals. BThe disadvantages of warmblooded animals. CThe differences between warmblooded and coldblooded animals. DThe advantages of both warmblooded and coldblooded animals. 解析：选C段落大意题。第二段主要讲了恒温动物和变温动物在体温调节和生活方式方面的差异。故C项正确。2According to the text, dinosaurs like Velociraptor_. Awere bigger than the first discovered dinosaursBmade scientists reconsider dinosaurs behaviorCmoved slower than the first discovered dinosaursDproved scientists were right about dinosaurs behavior解析：选B细节理解题。根据第三段中的“But as scientists found more bones of smaller, quicker dinosaurs, like Velociraptor, they realized that the creatures may have been much more active than they had thought. ”可知，这种又小又快的恐龙的发现使科学家开始重新考虑恐龙的行为习性。3It can be inferred that mesotherms grow _. Aas slowly as coldblooded animalsBas fast as warmblooded animalsCslower than coldblooded animalsDslower than warmblooded animals解析：选D推理判断题。根据第四段中的“warmblooded animals grow faster than coldblooded ones”及第六段中的“dinosaurs fell somewhere in between. mesotherms”可推断，类似恐龙这样的动物比恒温动物生长得慢。4The text is mainly about _. Ahow dinosaurs disappearedBthe growth areas of dinosaursCthe appearance and behavior of dinosaursDwhether dinosaurs were warmblooded or coldblooded animals解析：选D主旨大意题。通读全文可知，本文主要是介绍关于恐龙是恒温动物还是变温动物的研究。首段末句是主题句。B(2019全国卷)Monkeys seem to have a way with numbers. A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols consisting of numbers and selective letters with 025 drops 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 one 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 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, not 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 and 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. “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. BThey named them. CThey trained them. DThey measured them. 解析：选C细节理解题。根据第二段内容“A team of researchers trained three Rhesus monkeys to associate 26 clearly different symbols.with 025 drops of water or juice as a reward. The researchers then tested.”可知，实验开始前，研究人员先对猴子进行训练。6How did the monkeys get their reward in the experiment?ABy drawing a circle. BBy touching a screen. CBy watching videos. DBy mixing two drinks. 解析：选B细节理解题。根据第三段中的“If the monkeys touched the left side of the screen they would be rewarded with seven drops of water or juice.”可知，猴子通过触摸屏幕得到奖励。7What did Livingstones team find about the monkeys?AThey could perform basic addition. BThey could understand simple words. CThey could memorize numbers easily. DThey could hold their attention for long. 解析：选A推理判断题。根据第四段中的“the researchers noted that the monkeys would go for the higher values more than half the time, indicating that they were performing a calculation, not just memorizing the value of each combination”可知，研究人员注意到猴子超过一半的时间都会去触摸更高的数值，表明它们在进行计算，而不仅仅是记住每个组合的值，由此可推知，猴子会进行简单的加法计算。8In which section of a newspaper may this text appear? AEntertainment. BHealth. CEducation. DScience. 解析：选D推理判断题。本文主要介绍了科学家们对恒河猴进行的有关数字计算的科学实验，应出现在报纸的科学专栏中。. 七选五Everyone can benefit from making an effort to practice gratitude(感激) every day. The following three steps can help you start feeling more grateful, and appreciative of the good things in your life. Notice the Good Things in Your Life 1 Pay attention to the small everyday details of your lifenature, people, community, shelter, creature comforts like a warm bed or a good meal. And then start a gratitude journal. Making a commitment to writing down good things each day makes it more likely that we will notice good things as they happen. Enjoy the Feeling of GratitudeThere are moments when you naturally, right then and there, feel filled with gratitude. These are moments when you say to yourself，“Oh，wow, this is amazing！” or “How great this is！” Pause. 2 Let it sink in. Enjoy your blessings the moment they happen. Express GratitudeExpressing gratitude is more than being polite. 3 Show your appreciation to someone who really did something nice. Say：“It was really kind of you to.”，“ You did me a big favor when.” or “Thank you for being there when.”. 4 Hold the door open for the person behind you, even if it means waiting a little longer than you norma
