Unit 5.1 Starting out & Understanding ideas(Ⅰ)-【创新教程】2025-2026学年高中英语选择性必修第一册五维课堂Word课时作业（外研版2019）

Ⅰ.阅读理解 A Gardening is popular in many parts of the world.This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables.And it also does a lot of good to our health. Gardening connects people.When you are gardening, you are outdoors.So it is a perfect chance to meet and spend time with your neighbors.Most people love to talk about their hobbies, and gardeners are no different.They usually enjoy showing people what they are growing.And most of them enjoy sharing advice and stories about their gardens almost as much as sharing flowers and vegetables from their gardens. Gardening is a great activity for children.It gets them outdoors and off computers, televisions and cell phones.Gardening is also a great teacher.It can teach a child about where food comes from and healthy eating.It also helps them to understand that the natural resources (资源) are not 　inexhaustible　 and the importance of using them carefully. Then, when you garden, you must move around.All the different movements needed for gardening, like bending and lifting, work small muscles (肌肉) in the body.And you can easily get good exercise when you are digging holes or pulling grass. In a study, researches looked at more than 2,800 people over the age of 60.They studied their life habits, activities and health over a 16­year period.They found that gardening could lower the risk of future dementia (痴呆) by 36%.Gardening requires people to do many repeated actions, such as picking off dying flowers.These actions have a calming influence on the brain.The brain is still active but not in the same way when we use computers. You'll feel wonderful when what you grow in a garden looks, smells, feels and tastes good. 1．What can be inferred from Paragraph 2? A．Gardeners don't feel lonely. B．Gardeners are fond of sharing. C．Gardeners have many hobbies. D．Gardeners care about the environment. 2．What does the underlined word “inexhaustible” in Paragraph 3 mean? A．Useless.　　　　　　　 B．Special. C．Endless.

[语篇解读]　本文是一篇说明文。文章介绍了做园艺对人们健康的种种好处，从而鼓励人们做园艺。 1．A　[推理判断题。根据第二段中的“When you are gardening, you are outdoors.So it is a perfect chance to meet and spend time with your neighbors.”可知，当你在户外做园艺时，你有很好的机会遇到邻居并与他们共度时光。由此可推断，做园艺的人不会感到孤独。故选A。] 2．C　[词义猜测题。根据下文的“the importance of using them carefully”园艺可以让孩子们理解小心地使用自然资源的重要性，告诉孩子自然资源需要仔细利用。由此可以推测，本句要表达的是“这也能帮助孩子们明白自然资源并不是取之不尽的”。inexhaustible的构词法是“in(否定前缀)＋exhaust(词根：动词“耗尽”)＋ible(形容词后缀，意思为“可以的，能够的”)。可猜测inexhaustible意思为“用不完的”。故选C。] 3．B　[推理判断题。根据第五段中的“They found that gardening could lower the risk of future dementia by 36%，(他们发现做园艺能使老年人患痴呆症的几率降低36%)”可以推断，作者介绍这个研究的目的是为了说明做园艺对健康有益。故选B。] 4．B　[推理判断题。通读全文，文章第一段提到“And it also does a lot of good to our health”(它也对我们的健康有很多好处)，这是全文的主题；下文每一段都谈到园艺的一种好处，如园艺让你与人打交道、对孩子是一种很好的活动、可以让你四处走动锻炼身体、降低老年痴呆的风险、看到园中生长的东西，你会心情愉快等。由此可以推断，作者写这篇文章的目的是鼓励人们做园艺。故选B。] B California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor(因素)． The number of trees larger than two feet across has declined by 50 percent on more than 46,000 square miles of California forests, the new study finds.No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles.In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent. Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study.Woodcutters targeted big trees.Housing development pushed into the woods.Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源)． But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development. The loss of big trees was greatest in areas where trees had suffered the greatest water shortage.The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt(融雪)． Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season. 5．What is the second paragraph mainly about? A．The seriousness of big­tree loss in California. B．The increasing variety of California big trees. C．The distribution of big trees in California forests. D．The influence of farming on big trees in California. 6．Which of the following is well­intentioned but may be bad for big trees? A．Ecological studies of forests. B．Banning woodcutting. C．Limiting housing development. D．Fire control measures. 7．What is a major cause of the water shortage according to McIntyre? A．Inadequate snowmelt. B．A longer dry season. C．A warmer climate. D．Dampness of the air. 8．What can be a suitable title for the text? A．California's Forests: Where Have All the Big Trees Gone? B．Cutting of Big Trees to Be Prohibited in California Soon C．Why Are the Big Trees Important to California Forests? D．Patrick McIntyre: Grow More Big Trees in California [语篇解读]　本文是一篇说明文。根据一项研究显示，自20世纪30年代以来，加州已经损失了一半的大树，而气候变化似乎是其主要因素。 5．A　[段落大意题。第二段中，作者用具体数据说明了大树损失在各个地区的严重程度，没有任何地区幸免或不受影响，故选A。] 6．D　[推理判断题。根据第三段最后一句Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源)．可知，对野火的控制使得加利福尼亚的森林里挤满了小树，与大树争夺资源，也就是对野火的控制是善意的，但对大树产生了不利的影响。故选D。] 7．C　[细节理解题。根据最后一段the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.可知，造成加州水资源短缺的最大因素是温度升高，这导致树木向空气中流失更多的水分，以及更早的融雪，这减少了旱季对树木的供水量。故选C。] 8．A　[标题归纳题。通读全文可知，自20世纪30年代以来，加州已经损失了一半的大树，文章分析了引起该现象的几个主要因素。全文围绕“加州森林的大树都去哪儿了”话题展开，故选项A。] Ⅱ.阅读七选五 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 life­giving, 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 air with health care. G．All across the country, recovery centers have begun building Healing Gardens. [语篇解读]　本文是一篇说明文。文章介绍了新鲜空气对人体的各种好处。 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。E项“但是新鲜空气真得像你母亲说的那样对你有好处吗？”承上启下，故选E。空前的people tell us to “go out and get some fresh air”和选项中的“your mother always said”亦是呼应。] 2．A　[根据下一句中提到的“If the air you're breathing is clean...the air is filled with life­giving, energizing oxygen”可知，新鲜空气充满赋予人生命的，充满活力的氧气。再根据下文中“...breathe more deeply, allowing more oxygen to get to your muscles and your brain”是对前文的递进，在户外，更多的氧气进入你的肌肉和大脑。根据前面的分析可以推知，该空应该提到新鲜空气的基本作用，根据常识，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”可以推知，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G项“在全国，康复中心已经开始建造‘康复花园’。”these places就是指Healing Gardens。] 4．C　[前文介绍的是“康复花园”中的绿色植物对于病人康复的好的作用：绿色的正在成长的植物可以减轻压力，降低血压，使人情绪良好；空后提到“它给我们一种平和感”。该空起承上启下的作用，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也要指代这种情况。故选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“the sun's rays...give us beneficial Vitamin D”可知，该段介绍阳光的好处。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项“获得新鲜空气的另一个好处是阳光。”] 学科网（北京）股份有限公司 $$
