With the rapid development of industry and agriculture, air pollution, water pollution and waste pollution affect our daily life, health and even the balance of nature. Many wild animals are losing their homes and food because of pollution. As middle school students, we can’t solve all the problems, but we can take small but useful actions to protect the environment. First, we should save energy in our daily life. There are many practical things we can do in daily life. We can turn off lights, TVs and computers when we leave a room. We can also save water by reusing it. Second, we should reduce pollution. To reduce pollution, we are advised to use environmentally friendly bags instead of plastic ones. It’s important to develop a good habit of sorting rubbish and putting it into different bins. Besides, planting more trees is an effective way to make the air cleaner and prevent the wind from carrying away soil. What’s more, we can raise people’s awareness of environmental protection by telling its importance to our families and friends. We can ask them to walk or ride bikes more instead of driving cars. We can also recycle paper, bottles and cans to save resources. Small actions can make a big difference. If everyone tries their best to protect the environment, our world will become cleaner, safer and more beautiful. 11．The underlined word “affect” means ________. A．影响 B．保护 C．改变 D．节约 12．What can we do to save energy according to the passage? A．Keep lights on all day. B．Turn off lights when leaving a room. C．Use plastic bags as much as possible. D．Drive cars to work every day. 13．Why does the writer suggest planting more trees? A．Because trees can produce more rubbish. B．Because trees can make air fresh and protect soil. C．Because trees can increase air pollution. D．Because trees need a lot of water to grow. 14．What should we do with rubbish? A．Throw it everywhere. B．Sort it and put into bins. C．Burn it to produce energy. D．Bury it directly in the ground. 15．Which of the following is TRUE according to the passage? A．Pollution is good for people’s health. B．Students can do nothing to protect the environment. C．Small actions can make a big difference to the environment. D．We don’t need to save water or electricity. Waste sorting has become a key environmental protection activity in cities across China. It is a simple but effective way to protect our environment and build a green home. In our daily life, waste is divided into four kinds: recyclable waste, kitchen waste, harmful waste and other waste. Recyclable waste includes paper, plastic bottles and glass, which can be reused after being processed. Kitchen waste mainly comes from food, like vegetable leaves and fruit peels, which can be turned into fertilizer. Harmful waste includes batteries and expired medicine, which will pollute soil and water if thrown away randomly. Other waste refers to the waste that doesn’t belong to the above three kinds. Nowadays, many communities have put different colored rubbish bins to help people sort waste correctly. Volunteers also go to communities to teach people sorting rules and help them classify waste. More and more people realize the importance of waste sorting and take action in daily life. However, some people still don’t follow the sorting rules. We need more public education and everyone’s effort to make waste sorting a common habit. 16．What is the main idea of the passage? A．Ways to deal with kitchen waste B．The importance and rules of waste sorting C．How to make use of recyclable waste D．Environmental problems in cities 17．Which of the following is recyclable waste? A．Expired medicine B．Vegetable leaves C．Plastic bottles D．Used batteries 18．What can kitchen waste be turned into? A．Energy B．Fertilizer C．Paper D．Plastic 19．Why do communities put different colored rubbish bins? A．To make the community more beautiful B．To help people sort waste correctly C．To collect more rubbish D．To reduce the number of rubbish bins 20．What can we infer from the last paragraph? A．All people follow waste sorting rules. B．No one needs to learn sorting rules anymore. C．We still need to popularize waste sorting knowledge. D．Waste sorting is not necessary for everyone. Fantasy stories often feature walking trees, like Groot or the Whomping Willow. While real trees aren’t that athletic, science shows they do move, just incredibly slowly. Trees constantly seek sunlight and water. Young trees stretch their branches towards the sun in a process called phototropism. They need light to grow. If sunlight is blocked, they slowly bend towards brighter areas. Tree roots also move. They sense water in the soil and grow towards it. Sometimes, this causes problems when roots seek water inside pipes, even reaching into people’s toilets. There are tales of a “walking palm tree” in Central and South America that supposedly moves using its special roots. However, scientists say there’s no real evidence that trees actually get up and walk like those in the stories. While individual trees stay rooted, entire forests can move over very long periods. This is called forest migration (迁移). Trees don’t walk or fly, they migrate over generations by spreading their seeds. Animals like squirrels carry nuts. Birds eat berries and drop the seeds elsewhere. Wind blows seeds to new locations. Seeds that land in suitable spots grow into new trees. Historically, forests slowly migrated as climates changed, perhaps moving 100–500 meters per year. But today, human-caused climate change is damaging habitats much faster than forests can naturally move. Rising seas threaten coastal forests like mangroves. Warmer temperatures make it hard for spruce trees in Canada. Drier weather harms pines in the American southwest. “Trees just cannot keep up,” says ecologist Leslie Brandt: “Their habitats are changing faster than they can migrate.” To help, scientists are trying “assisted migration”. This means planting tree seeds in new areas where the future climate might suit them better. For example, in Minnesota, forests are suffering from more floods and harmful insects, so scientists are planting trees like cottonwoods and willows to replace dying maples (枫树). They work with local communities to ensure these changes meet everyone’s needs, as people rely on forests! Even though forests need to adapt, the goal isn’t to change them, but to help them survive. 21．What do scientists say about the “walking palm tree”? A．Its roots can damage water pipes. B．It moves quickly using special roots. C．It grows well in wet environments. D．There is no clear proof of its walking. 22．How do forests migrate naturally over generations? A．By seeds being spread to new areas. B．By roots growing towards water. C．By animals carrying adult trees. D．By scientists planting new seeds. 23．Why are scientists planting cottonwoods and willows in Minnesota? A．Their roots hold soil in place. B．Locals prize them for beauty. C．They survive floods and insect attacks. D．They outgrow maples in cold climates. 24．What is the text mainly about? A．Differences between fantasy trees and real ones. B．The role of seeds in tree growth. C．How climate change harms forests. D．Natural and assisted forest migration. 素养提升 三、补全对话 A: Hi, John! I saw you planting trees in the park yesterday.

B．The role of seeds in tree growth. C．How climate change harms forests. D．Natural and assisted forest migration. 【答案】21．D 22．A 23．C 24．D 【导语】本文是一篇说明文。树木虽自身移动极缓，但森林会通过种子传播自然迁移。然而，当下人类导致的气候变化使森林自然迁移受阻，科学家正通过“人工辅助迁移”助其生存。 【详解】21．细节理解题。根据第二段“However, scientists say there’s no real evidence that trees actually get up and walk like those in the stories. (然而，科学家们表示，并没有确凿的证据表明树木真的会像故事中的那样站起来走路) ”可知，科学家称没有明确证据能证明“行走的棕榈树”会行走。 22．细节理解题。根据第三段“Trees don’t walk or fly, they migrate over generations by spreading their seeds. Animals like squirrels carry nuts. Birds eat berries and drop the seeds elsewhere. Wind blows seeds to new locations. Seeds that land in suitable spots grow into new trees. (树不会走也不会飞，它们通过传播种子代代迁移。像松鼠这样的动物携带坚果。鸟儿吃浆果，把种子撒到别处。风把种子吹到新的地方。种子落在合适的地方会长成新树) ”可知，森林通过将种子传播到新的区域在数代间自然迁移。 23．细节理解题。根据最后一段“For example, in Minnesota, forests are suffering from more floods and harmful insects, so scientists are planting trees like cottonwoods and willows to replace dying maples. (例如，在明尼苏达州，森林遭受了更多的洪水和有害昆虫，所以科学家们正在种植像棉白杨和柳树这样的树木来代替垂死的枫树) ”可推断，科学家在明尼苏达州种植棉白杨和柳树是因为它们能在洪水和害虫袭击中存活下来。 24．主旨大意题。通读全文可知，文章先介绍树会缓慢移动以及森林自然迁移的方式，接着阐述人类活动导致的气候变化使森林自然迁移面临困难，最后提到科学家的“辅助迁移”措施。由此可推断，文章主要介绍了自然的和辅助的森林迁移。 素养提升 三、补全对话 A: Hi, John!
