课时练 1 2 篇阅读＋1 篇完形 Ⅰ 阅读理解 A (2020· 新疆维吾尔自治区适应性检测) Superstorm Sandy slammed into the eastern United States a few years ago. The winddriven water caused a lot of flooding, especially in the region’s subway system. Now two teens have invented a device that could help prevent future subway floods. In New York City alone, Super storm Sandy caused an estimated $19 billion in damage. Much of the floodwaters entered the subway system through its ventilation grates ( 通 风 栅 ). Those metal grills usually lie at ground level. When the system is shut down ahead of a flood, engineers try to cover those grates with plywood (胶合板) and sandbags. But the flooding often washes away those measures, which allows water to flow into the tunnels. Raising those grates even a tiny bit above ground level would cost a lot of money. Other ideas have included building tall chimneys around the holes. That would raise the grates and cost a lot of money, too. Kyle and Raymond came up with a different, less expensive idea. They designed a metal grate with a builtin, adjustable cover. When trains are running, one part of the grate slides open to bring in fresh air. But when the system is shut down, that part can be slid shut to completely block the grate. Their grate is the same size as the grates used now. So, it would be simple, they say, to lift out the old grate and drop in a replacement. Their design includes tamperproof features, which can prevent operation mistakes. They make sure that people don’t intentionally shut off airflow during normal conditions. For people with the proper key, it would only take a minute or two to close the grate ahead of a flood. 【解题导语】 本文主要讲述了几年前超级风暴 Sandy 猛烈袭击美国东部，造成了洪水 灾害，当地的地铁被洪水淹没。为防止地铁再次被洪水淹没，两位少年发明了一种装置。 1．What’s the second paragraph mainly about? A．The steps to operate grates. B．The measures to prevent flood. C．The function of plywood and sandbags. D．The disadvantage of present subway system. D 解析：段落大意题。根据第二段第一句可知，据估计超级风暴 Sandy 仅在纽约市就 造成了价值 190 亿美元的损失。文章接下来分析了超级风暴造成的洪水淹没地铁的原因：目 前的地铁系统存在很大的弊端。故选 D。 2．Which of the following words best describes the two teens’ new invention? A．Costly. B．Timesaving. C．Practical. D．Conventional. C 解析：推理判断题。根据最后一段第一、二句“Their grate is the same size as the grates used now. So, it would be simple, they say, to lift out the old grate and drop in a replacement.”可 知，他们使用的栅栏和现在使用的栅栏大小一样，所以，他们说这会很容易就可以把旧的栅 栏取出来，并放入一个替换栅栏；再结合最后一段最后一句可推知，新的栅栏操作起来也很 方便。故选 C。 3．What’s the purpose of designing the tamperproof feature? A．To replace the old grate correctly. B．To close the grate ahead of a flood. C．To ensure airflow in normal conditions. D．To stop the train speeding up unexpectedly. C 解析：细节理解题。根据最后一段第三、四句可知，设计干预防护的特点可以阻止 操作失误，有了干预防护，他们确保人们不会有意地在正常情况下关掉空气流通的功能，故 选 C。 4．Where does the text most probably come from? A．A news report. B．An adventurous story. C．An introduction to new equipment. D．A guidebook to making grates. A 解析：文章出处题。通读全文可知，本文主要讲述了两位少年发明了一种成本较低、 实用的地铁防洪装置以及该装置的特点和优势，应该属于新闻报道类文章，故选 A。 B (2020·合肥高三调研)While elephants born without tusks(长牙) are not unheard of, they normally form just 2 to 6 percent of the population. However, that is not the case at Mozambique ’ s Gorongosa National Park, where an astonishing 33 percent of female elephants born after the country’s conflict ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behavior expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivories. Poole says before the country’s 15yearlong conflict, the park was home to over 4，000 elephants. However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivories to get money. Of the less than 200 survivors, over 50 percent of adult females had no tusks. Therefore, it is not surprising that the park’s tuskless elephant population has grown greatly. This is not the first time researchers have observed a great change in the population of elephants. At Zambia’s South Luangwa National Park and Lupande Game Management Area, areas which were heavily hunted in the 1970s and 1980s, 35% of elephants of 25 years old or older and 13% of those younger than 25 are now without tusks. A 2008 study published in the African Journal of Ecology found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivories. The recent ban on ivories in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females to change the__trend． 【解题导语】 本文是一篇说明文。在 1992 年，在莫桑比克的 Gorongosa 国家公园， 有 33%的雌象生来就没有长牙，大象行为专家认为，这是人们为了获得珍贵的象牙，而对 大象进行持续不断的猎杀而造成的非自然的进化。 5．What is the probable cause of the phenomenon mentioned in Paragraph 1? A．Illegal hunting. B．Constant farming. C．A pure coincidence. D．Natural evolution. A 解析：细节理解题。根据第一段尾句“The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivories.”可 知，这位研究人员认为，由于持续不断地猎杀大象以获取珍贵的象牙，我们可能正在目睹物 种的非自然进化。据此可知，第一段中提到的现象的可能原因是非法猎杀，故 A 项正确。 6．Why did people kill so many elephants during the conflict in Mozambique? A．To get money by selling ivories. B．To develop new decorations. C．To provide food for local people. D．To make ivory products. A 解析：细节理解题。根据第二段第二句“However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivories to get money.”可知，然而在 1992 年内战结 束时，有大约 90%的大象因象牙被猎杀，从而获得钱。据此可知，人们猎杀大象是为了通 过销售象牙来获得钱，故 A 项正确。 7．Which of the following had the earliest record on tuskless elephants? A．Gorongosa National Park. B．South Luangwa National Park. C．Ruaha National Park. D．Lupande Game Management Area. C 解析：细节理解题。根据第一段的第二句可知，在 1992 年内战结束时，莫桑比克 的 Gorongosa 国家公园有 33%的雌象生来无长牙；根据第三段尾句“A 2008 study published in the African Journal of Ecology found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivories.”可知，Ruaha 国家公园在 1969 年有 10.5%的无长牙雌象，到 1989 年时，有大约 40%的无长牙雌象；据此可知，Ruaha 国家公园是最早记录无长牙雌象的地区， 故 C 项正确。 8．What does the underlined phrase “the trend” in the last paragraph refer to? A．Elephants facing greater danger. B．Elephants growing more slowly. C．Fewer female elephants staying alive. D．More female elephants being tuskless. D 解析：推理判断题。根据尾段第一句“The recent ban on ivories in both the US and China should help get rid of, or at least reduce, elephant hunting.”可知，最近美国和中国都颁布 了象牙禁令，这应该有助于消除或至少减少对大象的猎杀；结合该段第二句“However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females to change the__trend．”可知，科学家们并不确定对拥有较高比例无长牙雌象的大象们来说需要 多长时间才能改变这种趋势。据此可推知，画线词指代“更多的雌象无长牙”这一趋势，故 D 项正确。 Ⅱ 完形填空 (2020·郑州高三第二次质量预测)My father was born in a small town in the US.

But communicating with a submarine(潜艇) or a diver is not so easy. The lack of practical methods for sharing data between underwater and airborne(空气传播的) devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar signals used by underwater sensors reflect off the surface of water rather than reaching the air. Now, researchers at MIT have developed a method with the potential to revolutionize underwater communication. “What we’ve shown is that it’s actually feasible to communicate from underwater to the air，” says Fadel Adib, a professor at MIT’s Media Lab, who led the research. The MIT researchers designed a system that uses an underwater machine to send sonar signals to the surface, making vibrations( 震 动 ) corresponding to the 1s and 0s of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. “It has any number of potential realworld uses，” Adib says. “It could be used to find downed planes underwater by reading signals from sonar devices in a plane’s black box and it could allow submarines to communicate with the surface.” Right now the technology is low resolution. The initial study was conducted in the MIT swimming pool at maximum depths of around 11 or 12 feet. The next steps for the researchers are to see if TARF is workable at much greater depths and under varying conditions—high waves, storms, schools of fish. They also want to see if they can make the technology work in the other direction—air to water. If the technology proves successful in realworld conditions, expect “texting while diving” to be the latest underwater fashion. 【解题导语】 本文是一篇说明文，主要介绍了一项麻省理工学院的科学家发明的从水 下与地面上的人进行通信的技术。 1．What does the author mainly talk about in Paragraph 1? A．The future of video chat underwater and in air. B．The frustrations of developing underwater devices. C．The difficulty of communication from water to air. D．The current situation of communicating with a submarine. C 解析：段落大意题。通读第一段的内容可知，该段主要讲的是从水下与地面的人进 行通信非常困难，故选 C。 2．What does the underlined word “feasible” mean? A．Achievable. B．Convenient. C．Changeable. D．Alternative. A 解 析 ： 词 义 猜 测 题 。 根 据 第 二 段 第 一 句 “Now, researchers at MIT have developed...underwater communication.”可知，麻省理工学院的研究人员发明了一种可能改 变水下通信的方法，使从水下与地面上的人进行沟通成为可能，故 A 项“可实现的”与画 线词意思最相近。故选 A。 3．What do we know about TARF?

But during the summer, the barn is filled with city kids who have come to enjoy the farm. They’re members of the Fayette County Livestock(FCL) Club, which showcases skills as varied as cutting wool. The barn is where they look after the animals. “A lot of Lexington kids don’t know anything about farm life，” said Adria Meier, 17, who has looked after goats and sheep for three years. “There is so much to learn.” The dozen or so children who take care of their goats and sheep at the little red barn must do a sixhour class before they get an animal. They pay for their own animals but get special club programs, such as one that provides vet(兽医) care. Mahan lets the group use the barn for free, and the kids spend up to three hours a day there during the summer.But as his land gets sold, he doesn’t know whether the club can continue. What makes the FCL Club special is that most of the kids can’t just walk out their doors and take care of their animals. Most are driven to the barn by their mothers, who usually hang around and chat as their kids feed and exercise the animals. There are valuable lessons learned along the way. For instance, don’t cut wool off your goat when there is wind, and sheep are social animals and will cry loudly when separated. “Tending to animals helps teach us responsibility. Unlike learning to shoot an arrow, caring for an animal isn’t something you can simply abandon，” said Carly Playforth, 16, of Lexington. 【解题导语】 本文是一篇记叙文， 主要讲述了一群城里的孩子来到乡间农场体验不 同的生活，照顾农场动物的故事。 5．What is the requirement for kids before they get animals? A．Attend a class. B．Pay certain money. C．Have varied skills. D．Get special club programs. A 解析：细节理解题。根据第三段中的“must do a sixhour class before they get an animal”可知，得到动物之前，孩子们必须上一节六小时的课程，这个课程可能是培训孩子 们如何照顾动物的。 6．What do we know about the club? A．It offers services unconditionally. B．It pays for their use of the barn. C．It lets Mothers care for animals. D．It allows Mothers to push kids. D 解析：推理判断题。根据第四段中的“Most are driven to the barn by their mothers”可 推知，该俱乐部让孩子的妈妈督促孩子参与农场活动，故选 D 项。 7．How does Carly Playforth feel about the experience? A．Suspicious. B．Moved. C．Appreciative. D．Opposed. C 解析：观点态度题。最后一段首句是段落主旨句，作者引用 Carly Playforth 的话是 为了进一步说明因照顾动物而教会孩子们的珍贵东西，比如责任。由此可知，Carly Playforth 对这种经历是赞赏的(appreciative)。 8．What is the passage mainly about? A．Kids’ life on a sold farm. B．Valuable lessons learned on the farm. C．A special club intended for Lexington kids. D．A club activity of caring for farm animals. D 解析：主旨大意题。根据文章内容可知，本文重点介绍的是 FCL 俱乐部借助一个 农场举办的活动——让孩子们亲自照顾动物，在这一过程中，孩子们获益匪浅。故 D 项概 括最为全面。 Ⅱ 七选五 (2020·济南模拟)About one hundred years ago many educated people learned and spoke French when they met people from other countries. Today most people speak English when they meet foreigners. 1.________ There are more people who speak English as a second language than people who speak English as a first language. Why is this? 2 ．________ One of them is that English has become the language of business. Another important reason is that popular American culture(like movies and music) has quickly spread throughout the world. 3.________ Is it good that English has spread to all parts of the world so quickly? 4.________ It’s important to have a language that the people of the earth have in common. Our world has become very global and we need to communicate with one another. On the other hand, English is a fairly complicated language to learn and it brings its culture with it. Do we really need that? Scientists have already tried to create an artificial language that isn’t too difficult and doesn’t include any group’s culture. It is called Esperanto. 5.________ Maybe the popularity of English won’t last that long either. There are more people in the world who speak Chinese than any other language. Maybe someday Chinese will be the new international language. A．People like English. B．But it hasn’t become popular. C．It has brought its language with it. D．There is no doubt about the question.
