As opposed to a highly uncontrolled process, involving explosions and bouncy castles and total chaos, we suppose.（1）Why does the author mention the case of Yellowstone? A. pens have a hole in their cap is to prevent the cap from pletely obstructing the airway if accidentally breathed in. This is requested by the international safety standards ISO11540, except for in cases where the cap is considered too large to be a choking risk.t grow after you die. The holes at the top of Bic biro pens are there so that, if you swallow one accidentally, you can still breathe and won39。由此可知本文屬于科普文章。 （3）考查推理判斷。由此可推斷出研究人員飼養(yǎng)這種鵝是為了證實這種鵝是否能飛過珠峰。D.C.B.Whether they can manage to fly 8 hours to climb over Mount Everest.（4）Where does the text most probably e from? A.To see how many calories they burned per hour.（2）What can we learn from the wind tunnel experiment? A.s heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their bloodthe measured blood temperature dropped so it could take in more oxygen, the researchers report today in eLife. This cooling likely helps pensate for the very thin air, the team says.根據(jù)第四段中的“But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. ”但是熱量會隨著時間的推移而消失，不管周圍的物質(zhì)有多好，所以研究小組建立了一個化學(xué)儲存系統(tǒng)，可以將能量保持在一個穩(wěn)定的分子結(jié)構(gòu)中)可推斷，這種分子結(jié)構(gòu)的優(yōu)勢是相對穩(wěn)定。故選C。According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. 【點評】本題考點涉及細(xì)節(jié)理解，句義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，要求考生準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進行分析，推理，從而選出正確答案?；羧A德說有中學(xué)數(shù)學(xué)知識就足夠了。 （2）考查細(xì)節(jié)理解。. A.D.It attracts rock stars to practice.C. Over the past five years researchers in artificial intelligence have bee the rock stars of the technology world. A branch of AI known as deep learning, which uses neural(神經(jīng)的) networks to scan through large volumes of data looking for patterns, has proven so useful that skilled practitioners can mand high sixfigure salaries to build software for Amazon, Apple, Facebook and Google.正如所料，老年癡呆癥患者的葡萄糖吸收降低，故選B。 ”在二十多歲的時候，當(dāng)我們記不起鄰居的貓的名字或是主演一部著名電影的英俊演員時，我們覺得很有趣。Reduced uptake of glucose.C. forgetfulness.s disease.C.People can be forgetful at different ages.B.re forgetful that we should fear.s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it brain freeze. In our forties, we laugh it off as a senior moment and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful.

Cutting down on how much food we waste—which is roughly a third in the US—could help even more. The results are in the Proceedings of the National Academy of Sciences.t explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that. So that39。 You know those nutrition guidelines the government issues every few years?

RMIT39。 Solving math problems requires a plex level of involving the mental management of numbers, longterm rules and shortterm working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.has a possible effect on the future development of AIC.New Findings About Bees Having Numerical CogintionC.研究人員發(fā)現(xiàn)了蜜蜂能做基本的數(shù)學(xué)。但是數(shù)字認(rèn)知，比如精確的數(shù)字和算術(shù)運算，需要更復(fù)雜的處理。2．犇犇閱讀理解 What we found is that impacts vary across nations, but in the high173。 The food we eat takes a big toll on the environment.
