Ⅰ.阅读理解
Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. But 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 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 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 grasses.
In a study, researchers looked at more than 2,800 people over the age of 60. They studied their lifestyle habits, activities and health over a 16-year period. They found that gardening could lower the risk of future dementia (痴呆) by 36%. Gardening requires people 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.

Ⅱ.读后续写
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
Mother's gift
I grew up in a small town where the primary school was a ten-minute walk from my house. When the noon bell rang, I would race breathlessly home. My mother would be standing at the top of the stairs, smiling down at me.
One lunchtime when I was in the third grade will stay with me always. I had been picked to be the princess in the school play, and for weeks my mother had rehearsed my lines so hard with me. But no matter how easily I acted at home, as soon as I stepped on stage, every word disappeared from my head. Finally, my teacher took me aside. She explained that she had written a narrator's part to the play, and asked me to change roles. Her word, kindly expressed, still hurt, especially when I saw my part go to another girl.
I didn't tell my mother what had happened when I went home for lunch that day. But she sensed my pain. Instead of suggesting we practise my lines, she asked if I wanted to walk in the yard.
It was a lovely spring day and the rose vine was turning green. Under the huge trees, we could see yellow dandelions (蒲公英) in the grass in bunches, as if a painter had touched our landscape with a bit of gold. I watched my mother casually bend down by one dandelion. “I think I'm going to dig up all these weeds，” she said, pulling it up by its roots. “From now on, we'll have only roses in this garden.”
“But I like dandelions.” I protested. “All flowers are beautiful — even dandelions.”
My mother looked at me seriously. “Yes, every flower gives pleasure in its own way, doesn't it？” she asked thoughtfully. I nodded, pleased that I had won her over. “And that is true of people too，” she added. “Not everyone can be a princess, but there is no shame in that.” Relieved that she had guessed my pain, I started to cry as I told her what had happened. She listened and smiled reassuringly.
注意：1.续写词数应为150左右；
2．请按如下格式作答。
Paragraph 1：
“But you will be a beautiful narrator，” she said，
Paragraph 2：
After the play, I took home the flower.
参考范文：
Paragraph 1：
“But you will be a beautiful narrator，” she said，encouraging and comforting me as always as she did. My beloved mom, wearing a shining smile on her soft face, added.“The narrator's part is important, too.”Thanks to her encouragement, which calmed me down gradually, I began to accept that the narrator part was of vital significance. Time went so fast that it reached to the performance day. At first I was still nervous, but it was at that very moment that I found a dandelion in my pocket. I knew my mom passed the flower to me, which meant to be in company with me.
Paragraph 2：
After the play, I took home the flower. Mom carefully gazed at the dandelion, gently pressed it into the dictionary and grinned happily as she did. “We were perhaps the only people who would press such a sorry-looking weed.” Though decades have passed, I constantly recall our precious lunchtimes being together, grateful, because smiles on mother's face and her kind act foster a man like me now! And all those inspiring words like “Cease to struggle and you cease to live.”have been echoing in my mind as fresh as a daisy.UNIT 6 课时跟踪检测（一） 阅读理解专项练
Ⅰ.阅读理解
A
Today tropical rainforests are disappearing from the face of the globe. Despite growing international concern, rainforests continue to be destroyed at a pace over 80,000 acres per day. World rainforest cover now stands at around 2.5 million square miles. Human activities have had an effect on much of this remaining area.
Deforestation (森林滥伐) of tropical rainforests has a global effect through species extinction, the loss of important ecosystem services and renewable resources, and the reduction of carbon sinks. However, this destruction can be slowed, stopped, and in some cases even reversed (逆转). Most people agree that the problem must be solved, but the means are not as simple as building fences around the remaining rainforests or banning the wood trade. Economic, political, and social pressures will not allow rainforests to continue to exist if they are completely closed off from use and development.
So, what should be done The solution must be based on what is practical, not completely idealistic and depends on developing a conservation approach built on the principle of sustainable (可持续的) use and development of rainforests. Beyond the responsible development of rainforests, efforts to restore damaged forest lands along with the establishment of protected areas are key to securing rainforests for the long-term benefits they can provide for mankind.
Historic approaches to rainforest conservation have failed, as shown by the increased rate of deforestation. In many regions, closing off forests as untouchable parks and reserves has neither improved the quality of living or economic opportunities for the rural poor, nor stopped forest clearing by illegal woodcutters and developers.
The problem with this traditional approach to preserving wildland in developing countries is that it fails to develop proper economic motives for preserving the forest. Local people and the government itself must see financial returns to prove the costs of maintaining parks from economic activities.
语篇解读：本文是一篇说明文。文章说明了由于森林滥伐，热带雨林正在逐渐从地球上消失。作者根据以往森林保护失败的案例提出森林保护应该与发展当地经济相辅相成，否则只能是纸上谈兵。
1．What has caused some species extinction in the tropical rainforests
A．Human's destroying the trees.
B．Carbon sinks being reduced.
C．Lacking renewable resources.
D．Fences not being built around the rainforests.
解析：选A 细节理解题。根据第二段第一句中的“Deforestation (森林滥伐) of tropical rainforests has a global effect through species extinction ...”可知，人类对热带雨林的滥伐是造成一些物种消失的原因。
2．What can be inferred from the passage
A．Tropical rainforests can be easily preserved.
B．Rainforests must be closed off to be better protected.
C．Human activities have had an effect on tropical rainforests.
D．Economic returns can make some difference in protecting tropical rainforests.
解析：选D 推理判断题。根据最后一段最后一句“Local people and the government itself must see financial returns to prove the costs of maintaining parks from economic activities.”可知，经济效益对保护热带雨林有一定影响。
3．What is the author's attitude to tropical rainforest protection
A．Indifferent. B．Concerned.
C．Doubtful. D．Puzzled.
解析：选B 推理判断题。从第三段及第五段最后一句可推知，作者对热带雨林保护的态度是关注的。
B
Perhaps people have never realized that fashion materials should be one of the worst destroyers on our environment in countries across the world.
Everybody enjoys wearing warm fashionable sweaters, but they never realize how much harm they have done to the environment. Studies suggest that 70 percent of the damage to the grasslands is due to overgrazing (过度放牧). Because of that, the balance of nature is broken, extreme weather occurs frequently, species are under serious threat, and finally grasslands are becoming desert gradually. The major real cause driving this activity is that human beings demand for cheaper wool to make fashionable clothing.
What you might not know is that the natural fibers for making clothes are often taken from trees in ancient forests or other plants such as bamboo and cotton. This means that the clothes we buy and wear are contributing directly to destroying forests and habitats. In fact, cotton is by no means a fully environmentally friendly crops on the planet. For a start, it uses so much water to produce, which leads to the freshwater shortage across the globe. It can take 2,700 liters of water to make just one cotton T-shirt. Additionally, growing cotton requires high levels of pesticide and other dangerous chemicals that often pollute waterways and soil. As for man-made fibers, the damage done by them is far worse than other materials.
In recent years, retailers (零售商)have increased the number of fashion collection secession even-each month or week. Throwaway culture is known as “fast fashion” due to low prices. Every year, 100 billion new garments made from new fibers are produced, many of which soon end up in landfill (垃圾填埋场). A dress might cost a few pounds for the consumer, but there is a hidden cost to the wider environment including ecosystems and other species.
语篇解读：本文是一篇说明文。文章讲述了时尚材料是世界各国对环境的最大破坏者之一。文章以棉花为例说明了种植棉花是如何大量消耗资源以及危害环境的，指出人造纤维对环境危害最大。
4．According to the passage, the real destroyer on the grasslands is______.
A．overgrazing
B．human beings' need
C．unbalanced nature
D．change of weather
解析：选 B 细节理解题。根据第二段最后一句可知，推动这种活动的主要真正原因是人类需要更便宜的羊毛来制作时尚的服装。由此可知，草原上真正的破坏者是人类的需求。故选B。
5．Relatively speaking, which fiber does most harm to environment
A．The cotton fiber.
B．The tree fiber.
C．The man-made fiber.
D．The bamboo fiber.
解析：选C 细节理解题。根据第三段最后一句可知，至于人造纤维，它们所造成的损害比其他材料要严重得多。由此可知，人造纤维对环境危害最大。故选C。
6．What is the writer's attitude to the “fast fashion” culture
A．Opposed. B．Approved.
C．Neutral. D．Sympathetic.
解析：选A 观点态度题。根据最后一段最后一句可知，一件衣服对消费者来说可能要花几英镑，但对更广泛的环境，包括生态系统和其他物种来说，还有一个隐藏的成本。由此可推知，作者对于这种耗费环境资源的“快时尚”文化持反对态度的。故选A。
7．What is probably the best title for the text
A．Damage to Our Environment
B．Throwaway Culture
C．Destroying Forests and Habitats
D．Fashion Materials, the Hidden Environment Destroyer
解析：选D 标题归纳题。根据第一段可知，也许人们从来没有意识到，时尚材料应该是世界各国对环境的最大破坏者之一。文章以棉花为例说明了种植棉花是如何大量消耗资源以及危害环境的，指出人造纤维对环境危害最大。故D选项“时尚材料，隐藏环境破坏者”最符合文章标题。故选D。
