云南省昆明市官渡区第二中学2021-2021学年高一上学期第一次月考试卷说明：高一上学期第一次月考英语试题（试卷满分150分，考试时间150分钟）第Ⅰ卷阅读题现代文阅读（9分，每小题3分）阅读下面文字，完成1-3题①除了浪漫故事和诗意，月球仅是一块既无空气和水，又无生命的顽石。

然而，天文学家的一项计算机模拟计算却证明，月球是人类起源的大功臣。

②地轴的标的目的是用黄赤交角来表示的，这个角约为23.5度。

由于自转，地球的赤道鼓起一凸缘，太阳、月球和其他诸行星就会对此凸缘施加引力，并且各行星也会随着其间的彼此作用而逐渐变化本身的轨道。

因此作用在凸缘上的力是不竭变化着的，从而使地轴的标的目的发生摆动。

③有了月球，情况就大不一样，它不单能使其他各行星对地球凸缘施加的引力显得眇乎小哉，它还和太阳一起使地球不变地作每2600年一周的远动，使黄赤交角变化不超过1.3度。

④然而，这1.3度的变化也不是完全无害的。

许多科学家认为，冰川期可能就是这1.3度造成的。

但是，如果没有月球的不变作用，那就更不得了。

全球的环境将会被破坏成一时期有剧烈的四季变化，一时期又会无季节可分，这样也就不成能进化出像人类这样高度文明的生物了。

这也就是火星上无生命的原因。

因为目前火星自转轴的倾角为25度，可在0到60度间变化，并且它只有两个像摩天大厦那样大小的卫星，其引力不足以抵消其他行星的影响。

⑤据此，在宇宙空间来寻找行星人的范围就可大大缩小。

此外，月球正以每年约几厘米的速度在离我们远去，在10亿年后，它已远到不能再控制地球的自转轴了，那时，我们的地球将会发生巨大的变化。

1. “月球是人类起源的大功臣”，其主要依据解说正确的一项是（）A.月球与太阳和其他行星一起对地球赤道鼓起的凸缘施加引力，且引力作用最大。

B.月球和太阳一起使地球不变地作每2600年一周的远动，黄赤交角为23.5度C.月球不变了地球自转轴，从而使生物得到进化。

D.月球引力抵消了其他行星的影响，使地球有季节可分。

〖Why〗写作意图收听新闻播报仍然是现代社会的人们了解发生在世界各地的事件和获取信息的一种重要途径。

本单元关于自然灾害的新闻播报，从认识自然灾害的种类开始，到通过新闻介绍一些重大自然灾害，以及探讨面对自然灾害的威胁和所造成损失时人们可以采取的措施，引导学生运用听力策略，主动思考、预判听力要点以及运用新闻套语，模仿听力文本最后能够播报自然灾害新闻，从而呼吁学生重视自然灾害，树立防灾意识。

〖How〗文体结构和语言修辞四则关于自然灾害的播报内容属于新闻文体，语言科学准确，简洁明了。

文本语言中使用了新闻播报中的一些常见表达，例如：Good morning/evening、breaking news、those are the top news for today、early reports said that、more news about 、 was just seen、eyewitness said that、according to 等等。

纯音频形式的新闻播报没有文字和画面的辅助，信息完全通过播音员表达，他们往往语速较快，但语义连贯，语言简练，包含了新闻事件的重要信息。

This is the hottest time of the year in Thailand, so it makes sense that the biggest Songkran tradition is to throw water on people. Thais of all ages join in water fights, using buckets, hoses (软管)and water guns to celebrate the event.Boryeong Mud Festival, South KoreaDon't expect to come home clean after experiencing the Boryeong Mud Festival in South Korea. Famous for its mineral-rich mudflats, visitors rush to Boryeong in July to make themselves in mud, swim in grey pools and enjoy the party. There are even mudslides and a mud skiing competition for those who are seeking the extreme mud adventure!La Tomatina, SpainThe festival dates back to a parade in which some naughty teenagers knocked one performer off his stilts (高跷)and caused a fight of throwing vegetables accidentally. It was once banned until 1957 when the locals held a protest with a funeral. They carried a coffin containing a huge tomato as bands played a funeral march. In the following decades, La Tomatina has become a popular event. If you join the event, be aware that you squash (压扁) the tomato before throwing it. Have a great time but avoid causing any injury.Dia de los Muertos, MexicoBeginning at the midnight of October 31 and lasting through November 2,it is a festival when families gather together to remember those loved ones who have died, aiming to help them on their spiritual journey. On these days, Mexican families prepare special tables in their homes. On top of them they'll put photos of the dead and their favorite food. They also visit the graves of their beloved ones to show their respect to the dead.1.If you want to experience a special new year in a country, you can choose to visit ________.A.ThailandB.South KoreaC.SpainD.Mexico2.What may happen to you as a visitor in La Tomatina?A.You can perform stilts.B.Your can play funeral music in bands.C.You may be covered with mud.D.You may be attacked with tomatoes.3.Which festival is similar to the Tomb Sweeping Festival in China?A.Songkran.B.Boryeong Mud Festival. Tomatina.D.Dia de los Muertos.BDid you know people who live in different parts ofChinahave different habits and preferences? For example, people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical features.A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.The study also found differences in the immune systems of both groups. Most people in southernChinacarry the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.4. What did the new study focus on?A. Regions.B. Eating habits.C. Gene variations.D. Ethnic minority groups.5. What is the main function of the gene FADS2?A. It helps store fat.B. It helps digest meat.C. It helps gain weight.D. It helps treat an illness.6. According to the study, most northerners ________.A. sweat less frequentlyB. are immune to malariaC. prefer vegetables to meatD. are more sensitive to climates7. How many differences did the study find related to genes?A. Two.B. Three.C. Four.D. Five.CMany of us in China enjoy adding chilies (辣椒) toour food, but did you know that this spicy vegetable could also be dangerous? A 34-year-oldUSman recently ended up in hospital after eating a Carolina Reaper—the spiciest chili in the world. After taking just a single bite of one, the man suffered from serious headaches in the following few days, reported BBC News.In fact, reports of stomachache and headache caused by eating spicy food are not something unusual. But if chilies are harmful, why is it that human beings are the only animals to eat this vegetable? According to the website Huanqiu, about 600 million Chinese people—almost half of the national population—are chili eaters. So what makes people love chilies so much? The human body reacts to the burning feeling that comes from eating chilies by releasing natural chemicals that “produce a sense of happiness” , noted BBC News.And the benefits go even further than just personal enjoyment. A survey conducted by the Chinese Academy of Medical Sciences found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week. The number decreased to 14 percent for those who eat spicy food six to seven times a week. And another study done by theUniversityofVermontcame to a similar conclusion. “The data encourages people to eat more spicy food to improve health and reduce death risk at an early age,” Liu Qi, a nutritionist at the Harvard TH Chan School of Public Health, told BBC News.Chilies have anti-cancer quality and the ability to increase our metabolism (新陈代谢). So, don't worry if you love spicy food. It seems that chilies are actually good for us—except for the Carolina Reaper, perhaps.8. The example of a 34-year-old American is mentioned in Paragraph 1 to prove ________.A. chiliescan be beneficialB. chilies are popular inAmericaC. chilies can be dangerousD. serious headaches can be dangerous9. Eating chilies gives people a sense of happiness by_______.A. decreasing death rateB. releasing natural chemicalsC. curing serious headachesD. providing enough nutrition10. Which of the following statement is TRUE?A. Human are the only animals to eat chilies.B. Stomachache and headaches caused by chilies is something unusual.C. The more chilies you eat, the healthier you are.D. Chilies have anti-cancer quality but it can't increase our metabolism.11. The writer wrote the passage to ________.A. warn people of the dangers of chiliesB. ask people to eat Carolina ReaperC. encourage people to eat more chiliesD. tell people the benefits of chiliesDAs every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phone’s batteries can be replaced fairly cheaply — or the whole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries fora number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。
