1、二十一必修5 Unit 1Great scientists(限时35分钟). 阅读理解A(2021北京模拟)Researchers continue to show the power behind our sense of smell. Recent studies have found, among other things, that the smell of foods like pizza can cause uncontrollable anger in drivers on roads. The review explains that smell is unique in it
2、s effects on the brain. According to Conrad King, the researcher who carried out the review, “more than any other senses, the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings. This is why the smell of baking bread can destroy the best intentio
3、ns of a dieter. ”Smell, which dictates(决定) the unbelievable complexity of food tastes, has always been the least understood of our senses. Our noses are able to detect up to 10, 000 distinct smells. Our ability to smell and taste this extremely large range of smells is controlled by something like 1
4、, 000 genes, which make up an amazing 3% of the human genome. Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004 for their ground-breaking research on the nature of this extraordinary sense. These two scientists were the first to describe the family of 1, 000 olfacto
5、ry (嗅觉) genes and to explain how our olfactory system works. According to one study in the research review, smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users. They are then more likely to speed and experience uncontrollable an
6、ger on roads. The most reasonable explanation is that these can all make drivers feel hungry, and therefore desperate to satisfy their appetites. In contrast, the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers impatience. Similarly, the smells
7、of lemon and coffee appeared to promote clear thinking and mental focus. However, the way genes regulate smell differs from person to person. A study by researchers in Israel has identified at least 50 olfactory genes which are switched on in some people and not in others. They believe this may expl
8、ain why some of us love some smells and tastes while others hate them. The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors. 【文章大意】文章主要介绍了人类的嗅觉基因和嗅觉系统, 科学家们通过研究嗅觉基因和嗅觉系统是如何工作的, 发现了嗅觉对我们生活的影响。1.

A team of scientists announced on January 6, 2015
15、 that they had identified eight planets beyond our solar system, three or four of which orbit in their stars “Goldilocks Zone” the region where temperatures are not too hot or too cold for water, which is a necessary ingredient for life as we know it, to exist liquid form. This may be good news for
16、people hoping that Earth is not the only inhabited world in the universe. The scientists, led by Dr. Guilermo Torres of the Harvard-Smithsonian Center for Astrophysics, made the discoveries using data collected by the planet-seeking Kepler telescope. NASA launched Kepler in 2009. Since then, the tel
17、escope has identified more than 1, 000 planets outside of our solar system. Torres and his team analyzed the data about the eight newly discovered world to determine which ones are most likely to be similar to our Earth. Among the new discoveries, the scientists say the planets called Kepler 438b an
18、d 442b are the closest to Earth. Kepler 438b is just about 10% larger than our planet, and gets 40% more of its energy from its star than Earth receives from the Sun. Temperatures there would be about 140 degrees. Kepler 442b is about 33% larger than Earth, but receives 30% less energy from its star
19、. That would make it a potentially chillier world than our own. Torres says it is possible for life to exist and survive in either of those temperatures, but for that to happen, these planets would need to have another key ingredient for life: a heat-trapping atmosphere like Earths. While these find
20、ings add to the possibility that life exists beyond Earth, Torres cautions against drawing conclusions. “We are not claiming they are inhabited, ” he says. In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unk
21、nown whether these planets contain life. But the discovery of planets in their stars habitable zones suggests that somewhere out there, some form of alien life may have taken hold. 【文章大意】本文是一篇说明文。讲述了科学家宣布找到了太阳系外的另外八个星球, 其中三四个星球的运行轨道温度适宜, 适合水的存在。这使人们相信地球外还可能存在生命的迹象。5.

23、这个地区, 水的温度既不太热也不太冷, 能够以液体的形式存在。故可推理得知, 八颗行星中的其中一些可能存在生命。6. Which statement about the discovery of Torres and his team is TRUE? A. Kepler 438b is too hot for any life to exist on. B. Kepler 438b and 442b are the farthest to Earth. C. They have made the discoveries through Kepler. D. They have discove

26、for life: a heat-trapping atmosphere like Earths. ”可知, 开普勒442b缺少能够让生命存在的另一个关键组成部分: 大气层。8. About their exploration, Torres wants to indicate that _. A. there is a lot left to learnB. they have had decisive gainsC. it is the first in human historyD. it is certain for life on the planets【解析】选A。推理判断题。根据
27、最后一段第三句“In fact, these planets are so far away that the scientists cannot observe them directly, which can be explanation for why for now it remains unknown whether these planets contain life. ”可知, Torres认为这些行星如此遥远以至于科学家们无法直接观测到它们, 这就可以解释为什么目前还不清楚这些行星上是否存在生命。Torres想要暗示我们还有很多很多东西需要了解。【知识拓展】长难句分析In fa

The study found women who lived to 90 were, on average, taller and had
30、 put on less weight since the age of 20 as compared to women who were shorter and heavier.1 However, men saw more benefit from physical activity than women. In 1986 researchers asked over 7, 000 Norwegian men and women between age 55 and 69 about their height, current weight, and weight at age 20. B
31、oth genders also told researchers about their current physical activities. 2 The men and women were then sorted into daily activity quotas: less than 30 minutes, 30 to 60 minutes, and 90 minutes or more. Men and women in the study fared very differently when it came to the impact of body size and ex
