【正文】 Rob. As we all know, doctors are a stressful profession. When faced with life and death, they need to save the patient39。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團。Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質(zhì)使得捕食者對食物不那么感興趣，從而保護自己免受捕食者的傷害。C.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.t know how appealing it is.（1）The sea hare defends itself from predators by ________. A.

Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language. They found that people learn language using two memory systems: declarative and procedural. Memorizing vocabulary, for example, is a declarative memory process. But learning grammar is, mostly, a procedural memory process.By referring to data from other studies on language.（2）Which of the following is an example of motor memory? A.A second language.（4）What39。根據(jù)第五段中的“Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language.”可知，該團隊通過研究其他語言學習的成果，得出的結(jié)論，故選D。根據(jù)第三段中的“Ullman says his research shows that the human brain does not have a special area or system for making language. Over time we have simply reused or coopted (指派) parts of our brain for language.”以及全文可知，人類的語言學習是由大腦前區(qū)完成的，該區(qū)域早于人類本身。 Opossum (負鼠) Hoatzin (磨雉) The graceful sea hare is plain in taste in the first place, so it39。releasing substance to make predators unable to smell itD.根據(jù)從而可以推斷出，千足蟲是擁有多種防御機制的物種。 names and roles on their caps.

Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up nonverbal cues. For instance, if a student smiles at Will, he responds by smiling back. This twoway interaction not only helps attract the students39。 The program, in place since August 2018, has been a great success thus far. Ravishankar says, What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention. However, regardless of how popular it bees, Will is unlikely to replace human educators any time soon.（1）What was special for some elementary school students in Auckland?

But it es from an idea of the past.”和第五段“He pared it to the milkman model of the 1950s in the United States. Back then, someone brought milk to your doorstep in glass bottles and then left with empty bottles. These could be cleaned and used again. The result is zerowaste.”可知，Loop購物模式的想法來自于過去送奶工模式，是一種可以杜絕零浪費的模式。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇環(huán)保類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us health
