单元限时训练(一)　A卷 [对应学生用书P148] (限时40分钟) Ⅰ.阅读理解 A 1．TrueCar.com Top dealers compete for your business by offering lower prices. TrueCar spends a lot of money and resources on making sure the entire car renting experience is simple and straightforward. If you're in the market for a new car, give this site a try first. TrueCar's network checks many of the prices in your area and gets you the best price for the car you're looking for. 2．Carvoy.com It offers more control by allowing you to “build your car” and select your rental plan. The “build your car” option is one of the better options for those looking to add on features to their car. If you're looking for cars with options like a sunroof or navigation (导航), it's Carvoy that makes it very easy to get started with the process. 3．CarsDirect.com They have a large collection of new and used cars, and also provide resources for car comparisons. In the business for many years, they are one of the first online car outlets. They have a staff that can usually help you if you give them a call. Their phone support is very good and they are mostly located in the United States. 4．CarRent.com It delivers your rental car to the door, which is actually a huge selling point. Many people don't like to go to a dealership or even drive somewhere to pick up a car. Imagine renting a car and having it delivered right to your doorstep, no driving necessary! 5．CostcoAuto.com It offers member-only savings, many car selections and an easy sign-up process. The deals through Costco are great and unique. Many times they have deals with General Motors cars like Chevrolet. There are a lot of deals to be done, but the one thing that Costco does not do is negotiate the price. [语篇解读]　本文是一篇应用文，主要介绍了几个出租汽车的网站。 1．What's the selling point of TrueCar.com? A.Its most reasonable prices for cars. B．The diversity of its used cars. C．Its delivery service to your door. D．The special offers to its members. A　[推理判断题。根据第一部分中的“TrueCar's network checks many of the prices in your area and gets you the best price for the car you're looking for.”可知，该网站可以为顾客提供合理的汽车价格，故选A。] 2．What is the special service that Carvoy.com provides? A．You can have other functions added to your car. B．You can rent a car more easily than elsewhere. C．You can design the whole car by yourself. D．You can have better operation over your car. A　[细节理解题。根据所在部分“The ‘build your car’ option is one of the better options for those looking to add on features to their car.”可知，该服务可以为车辆增加一些功能，故选A。] 3．If you are a good bargainer, it's wise to avoid dealing with ． A．CarsDirect.com B．Carvoy.com C．CarRent.com D．CostcoAuto.com D　[推理判断题。根据最后一段中的“There are a lot of deals to be done, but the one thing that Costco does not do is negotiate the price.”可知，Costco不会讨价还价，故不适用于那些善于砍价的人，故选D。] B The goal of every plant and animal is the same：to create the next generation.The way a plant makes another generation of its species is by making seeds.Flowers are the tools that plants use to make their seeds. The job of a flower is to help its pollinator put pollen(花粉) exactly in the right place at the right time to make a seed.When a plant's flower succeeds in this, the plant gets to pass the secret for this success to the next generation, through the genetic code in its seeds！When a plant fails to grow up and make seeds, its genetic code does not get passed on.It becomes a loser in the game of life. The environment is constantly testing each plant.Competition for sunlight, water, nutrients and space is fierce.Herbivores(食草动物) are hungry and plants are their breakfast, lunch and dinner！Only the strongest individuals survive long enough to reproduce.These survivors keep making seeds, letting the environment select the winners and losers.Through this selection process plants have evolved (进化) to survive life in every habitat on our planet.This evolution has filled even the harshest habitats with life, including cold high mountains. Although the pollination of a flower may appear to happen by accident, plants and pollinators have been practicing for millions of years to make sure that this “accident” happens.Often a plant and pollinator co-evolve (evolve together), adapting to (适应) changes in each other to improve their own survival.A plant species may depend on a single species of pollinator to make its seeds.Likewise, many pollinators rely on one plant species to provide all the food for their young. [语篇解读]　本文是一篇说明文。文章主要讲述了植物是如何创造下一代的。 4．Which of the following is a necessary factor for a plant to become a winner in the game of life? A．The plant fails to grow up. B．The plant makes no seeds. C.There are no pollinators. D．The plant's genetic code gets passed on. D　[细节理解题。根据第二段内容可知， A、B、C三个选项都是错误的， 再结合该段倒数第一、二句“When a plant fails to grow up and make seeds, its genetic code does not get passed on.It becomes a loser in the game of life.”可知， 遗传密码得以传递是植物在生存游戏中获胜的必要因素。] 5．From the third paragraph we can infer that ． A．the environment is very important for a plant to survive B．herbivores can increase the development of plants C．only the strongest plants can have seeds to reproduce D．sunlight, water, nutrients and space are equal for all the plants A　[推理判断题。根据第三段第一句“The environment is constantly testing each plant.”及本段内容可推断， 环境对于植物的生存起非常重要的作用。] 6．The underlined word “harshest” in the third paragraph probably means “ ”． A．severest　　　　　 B．busiest C．richest D．most valuable A　[词义猜测题。根据画线词后的“including cold high mountains”可判断，即使是在有生命的最严酷的栖息地，也充满了这种进化过程。] 7．The last paragraph tells us a truth that ． A．the pollination of a flower happens only by bees B．plants rely on pollinators to provide all the food for their young C．plants and pollinators depend on each other to survive D．pollinators depend on plants to make seeds C　[推理判断题。根据最后一段的内容可知， 植物和虫媒是相互依存的。] Ⅱ.七选五 Is Fresh Air Really Good for You? We all grew up hearing people tell us to “go out and get some fresh air”． 1 According to recent studies，the answer is a big YES，if the air quality in your camping area is good. 2 If the air you're breathing is clean—which it would be if you're away from the smog of cities—then the air is filled with life-giving，energizing oxygen.If you exercise out of doors，your body will learn to breathe more deeply，allowing even more oxygen to get to your muscles(肌肉) and your brain. Recently，people have begun studying the connection between the natural world and healing(治愈). 3 In these places patients can go to be near nature during their recovery.It turns out that just looking at green，growing things can reduce stress，lower blood pressure，and put people into a better mood(情绪).Greenery is good for us.Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 4 It gives us a great feeling of peace. 5 While the sun's rays can age and harm our skin，they also give us beneficial Vitamin D．To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside.It takes sunscreen about fifteen minutes to start working，and that's plenty of time for your skin to absorb a day's worth of Vitamin D. A．Fresh air cleans our lungs. B．So what are you waiting for? C．Being in nature refreshes us. D．Another side benefit of getting fresh air is sunlight. E．But is fresh air really as good for you as your mother always said? F．Just as importantly，we tend to associate fresh air with health care. G．All across the country，recovery centers have begun building Healing Gardens. [语篇解读]　这是一篇说明文。文章介绍了新鲜空气的好处：新鲜空气中的氧气和阳光对人们的身心健康均有好处。人们已经开始利用大自然和治愈疾病的关系，建造“康复花园”给病人治疗了。 1．E　[根据下一句中的“the answer is a big YES”可知，该空应该是一个一般疑问句，选项中只有E选项是一般疑问句。再根据空前的“go out and get some fresh air”可知，E项中的“fresh air”与之呼应。] 2．A　[根据前面的分析可知，该空应该提到新鲜空气的基本作用。根据常识和本段下文内容可知，我们知道吸入的空气首先进入的是肺部，然后才会使我们的肌肉和大脑受益，故该空应选A选项(新鲜空气清洁我们的肺部)。] 3．G　[根据下一句中提到的“these places”可推知，该空应该提到表示地点的复数名词。选项中只有G选项提到该类名词，故选G项(在全国，康复中心已经开始建造“康复花园”)。these places指G项中的Healing Gardens。] 4．C　[前文介绍的是“康复花园”中的绿色植物对病人康复的积极作用。空后提到“它给我们一种平和感”。故设空处起承上启下的作用，仍然要提到处于“康复花园”这种自然环境中的好处，空后的It也是指代这种情况。故应选C项(身处大自然可以使人精神焕发)。] 5．D　[根据下文中提到的“While the sun's rays...give us beneficial Vitamin D．”可知，该段介绍的是阳光的好处。故该选项应该提到阳光。选项中只有D选项涉及“阳光”，故选D(获得新鲜空气的另一个好处是阳光)。] Ⅲ.完形填空 As our Earth's temperature warms up because of climate change, it is having unexpected effects on our world's forests.When temperatures rise, trees close their skins to 1 the loss of water, and this, in turn, slows down the 2 of photosynthesis (光合作用).As a result, these trees are shorter and grow slowly, as well as have a 3 death rate. Climate change also increases the 4 of droughts and wildfires.After wildfires, it takes a while for the forest systems to 5 ， and in some cases, the forests are 6 permanently.Trees that are stressed are also 7 to attacks by bacteria (细菌).In tropical forests, vines that use the trees as 8 can often choke the trees and rob them of nutrients.Finally, humans have 9 the forest landscape through logging.When trees are replanted on the soil, they will never grow as large as the 10 trees that were cut down. As these forests disappear, species that once called them “home” are forced to change, 11 the variety of those systems. 12 ， some endangered species are unable to 13 and die.Old-growth forests are disappearing in all regions of our world.When forests die, younger forests that are reestablished in the same area grow back weaker and smaller 14 poor vegetation (植被).With trees dying increasingly and continuously, will future generations 15 out on the wonders of forests?
