www.ks5u.com 话题十七 自然生态(B) Ⅰ.阅读理解 A [2019·黑龙江六校协作体一模] What do you do as spring sets in? Taking off your warm winter coat, and putting it away? For humans, taking off winter coats is a oneminute task. As it turns out, not all animals are so capable. Snowshoe rabbits live in the mountain ranges of North America, and have a pure white coat during the winter time to match the snowy surroundings and to help avoid being caught. And they take off winter coats for a darker brown fur color to match the dirt and leaves after the snow melts(融化) in the spring. Sounds like a great way to escape from their natural enemies, right? However, concern begins when scientists begin looking at how the warming climate will impact the rabbits. There are more and more white rabbits in the middle of a brown habitat(栖息地), where the snow has already melted away. This is a problem for them, as they are more easily seen by their natural enemies, giving them a “mismatch” problem. Snowshoe rabbits time the coat change in spring from white to brown based on the change in day length, not the temperature or the presence of snow in their habitat. Nowadays, the snow is melting a week on average before the change in day length signals the change in coat color, leaving the rabbits exposed to their natural enemies. Some predictions put the rabbits in up to 8 weeks of a white coat in a brown, snowless habitat by the end of this century. This_timeline_could_spell_doom_for_their_populations,_as their natural enemies will have nearly 2 months of easily spotting them. Fortunately, scientists have found areas with snowshoe rabbits in color from white to brown in the same place, meaning the timing of the coat change can be influenced by the environment. Snowshoe rabbits reproduce quickly, and if the color change timing is passed down then it is possible for rabbits to change coats accordingly. By protecting areas with variable ones, we can give snowshoe rabbits the opportunity to adapt to the changing climate. 1.Why does the author mention humans' taking off winter coats? A.To stress climate change is influential. B.To imply animals should be taken care of. C.To lead to the problem of snowshoe rabbits. D.To show differences between man and animals. 2.What has made scientists worry about snowshoe rabbits? A.They fail to keep their white color. B.They are active in freezing winter. C.They are easily been caught. D.They can't get rid of white fur when snow melts. 3.What can be inferred from the underlined sentence in Paragraph 4? A.Rabbits' enemies are stronger. B.More rabbits will be killed. C.The rabbit population will boom. D.The rabbits may die out in the future. 4.Which of the following can best conclude the text? A.Survival of the Fittest B.Importance of Colors C.Natural Selection D.Timing of Coat Change B [2020·高考桂林市、崇左市联合模拟考试] The world is a greener place than it was 20 years ago. A study published in the journal Nature Sustainability said that recent satellite data reveals a greening pattern that is prominent(显著的) in China and India. The study shows that human activity in China and India dominates this greening of the planet, thanks to tree planting and agriculture. The effect comes mostly from ambitious treeplanting programs in China and intensive agriculture in both countries. “China and India account for onethird of the greening,”said lead author Chi Chen of Boston University. “That is a surprising finding, considering the vague idea of land degradation(毁坏) in populous countries from overexploitation,” added Chen. China alone accounts for 25 percent of the global net increase in leaf area with only 6.6 percent of global vegetated area. The greening in China is from forests (42 percent) and croplands (32 percent), but in India, it is mostly from croplands (82 percent) with the minor contribution from forests (4.4 percent). China's outsized contribution to the global greening trend comes in large part from its programs to conserve and expand forests with the goal of preventing land degradation, air pollution, and climate change. “Once people realize there is a problem, they tend to fix it,” said Rama Nemani, research scientist and coauthor of the study. “In the 1970s and 80s in India and China, the situation around vegetation loss was not good. In the 1990s, people realized it, and today things have improved. Now we see that humans are contributing.” Land area used to grow crops is comparable in China and India-more than 770,000 square miles-and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production. This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more has increased by about 35%~40% since 2000 to feed their large populations. 5.What did the study mainly find? A.India and China are leading the global greening effort. B.Intensive agriculture is the cause of global land degradation. C.China and India has got the largest forest coverage in the world. D.Agriculture is more helpful in expanding green areas than treeplanting. 6.How is China different from India in contributing to the global greening? A.India reduced croplands to prevent the overexploitation. B.India increased forest by planting around croplands. C.China changed more lands into forest by planting trees. D.China controlled the increase of its population. 7.What does Nemani think about humans in China and India in protecting the Earth? A.Ambitious. B.Responsible. C.Passionate. D.Tolerant. 8.What does the passage finally suggest humans should make good use of? A.Forest. B.Trees. C.Croplands. D.Food.

Let's find out together.’is a wonderful way to get the ball rolling”,并与上文中的“Inspire curiosity”呼应可推知,此处表示鼓励孩子一起探索你自己也不知道答案的问题,从而引起好奇心,故选B项。 2.答案与解析:A 根据空后一句“If you have to carpool(拼车) in the morning,turn off the devices instead and encourage your children to look out of the window”可推知,开车时关掉电子设备,多看看窗外也是一种与自然接触的方式,故选A项。 3.答案与解析:C 承接上文“Time in nature is an essential investment in your children's health and wellbeing”和空后的“nurturing creativity...as parents”可推知,如果想要培养出健康、明智的孩子,培养他们的创造性和好奇心也是作为父母的责任,故选C项。 4.答案与解析:G 根据上文“Observing the stars offers a deeper and wider understanding of the universe”可推知,和孩子一起观察星空能够加深对自然界的理解,与G项呼应,故选G项。 5.答案与解析:D 承接上文“Plant a small garden”,并与下文“Bean and pea plants grow quickly and can be eaten when mature, so teach your children about food and the wonder of growth”呼应可推知,此处作者建议父母开辟一个小菜园,帮孩子种点蔬菜,一起见证它们生长的奇迹,故选D项。 Ⅲ.语法填空 体裁:说明文 题材:交通 主题:运河 【文章大意】 文章主要讲述了运河的重要作用。 1.答案与解析:a 考查冠词。此处泛指“一个干旱的国家”,且dry的发音以辅音音素开头,故填不定冠词a。 2.答案与解析:to irrigate 考查非谓语动词。这里表示挖沟壑的目的。故用动词不定式表示目的。 3.答案与解析:when 考查定语从句。分析句子结构可知,空处引导定语从句,先行词为“days”,空处在从句中作时间状语,故用when引导该定语从句。 4.答案与解析:joining 考查非谓语动词。分析句子结构可知,join与主语a ditch为逻辑上的主谓关系,故此处要用其现在分词形式作定语。 5.答案与解析:conveniently 考查词形转换。此处修饰“can be moved”要用副词形式。 6.答案与解析:save 考查时态和主谓一致。根据语境可知,此处表示通过缩短行程能节省船只时间,为一般性描述,应用一般现在时;句子的主语“Some canals”为复数,故填save。 7.答案与解析:shorter 考查形容词的比较级。根据语境可知,此处含有比较的含义,故填形容词的比较级。make sb./sth.+adj.为固定用法,意为“使某人/某物……”。 8.答案与解析:are situated 考查动词的时态、语态和主谓一致。此处为一般性描述,应用一般现在时;be situated意为“坐落在”;此处表示位于内陆的一些城市。that引导定语从句,先行词为cities,that在从句中作主语,表示复数概念,故填are situated。 9.答案与解析:factories 考查名词的单复数。根据语境以及前面的“fields”可知,这里表示不止一座工厂。故填factories。 10.答案与解析:in 考查介词。be in use为固定用法,意为“在使用中”。故填in。查看更多
