人教版英语九年级下册unit4单元测试题 (时间：45分钟 满分100分） I.阅读理解 A Nowadays, plastic pollution has become one of the most serious environmental problems across the world. Every year, billions of plastic goods are thrown away carelessly in daily life, and most waste plastic finally ends up in oceans or farmland soil. Unlike paper and wood, ordinary plastic needs hundreds of years to break down completely in nature. It poisons soil, pollutes fresh water and causes great danger to sea animals and human health step by step. To solve this problem, many cities have made strict rules to limit single-use plastic products. Supermarkets ask shoppers to bring reusable cloth bags instead of thin plastic ones. At school, teachers teach students the three golden rules: Reduce, Reuse and Recycle. Reduce means cutting down our use of plastic at the very beginning. For example, we can choose drinks in glass bottles rather than disposable plastic bottles. Reuse tells us to use things many times: empty plastic bottles can be turned into beautiful flower pots or practical storage boxes. Recycle requires us to sort rubbish carefully, so factories can turn waste plastic into new daily products again. Small daily actions really make a big difference to our living planet. If everyone follows the three Rules in daily life, we will greatly cut down plastic pollution and protect our warm living home for the future. 1.  How long does common plastic take to break down fully? A. A few months   B. Hundreds of years   C. Several weeks   D. One year 2. The underlined word “limit” in Paragraph 2 means ______. A. 限制   B. 生产   C. 售卖   D. 回收 3. Which action matches the rule of “Reuse”? A. Buying fewer plastic bottles in shops B. Putting different rubbish into different bins C. Turning empty plastic bottles into flower pots D. Using paper cups instead of disposable plastic cups 4. Why do schools teach students the three Rules? A. To let students learn the history of plastic B. To help students reduce plastic pollution in daily life C. To train students to work in recycling factories D. To ask students never to use any plastic products 5. What is the main idea of the whole passage? A. The history of plastic material production B. Methods to fight plastic pollution with the 3R rules C. How sea animals live in polluted ocean water D. Different kinds of rubbish in city landfills B Many people know recycling helps protect the earth, but few people realize how much valuable natural resources it can save in our daily life. A scientific study shows that recycling one ton of paper can save 17 trees and thousands of liters of fresh water. However, in most ordinary families around the city, lots of recyclable（可回收的）waste is still mixed with common rubbish and thrown away together directly. This bad situation makes many environmental workers feel deeply worried about our future living environment. If we keep ignoring small waste problems every day, the pressure on nature will become heavier year by year. Two Grade 9 students started a “Plastic-Free Campus” project in their school last term. They put more recycling bins in different hallways, held lively environmental speeches every two weeks and called on classmates to stop using disposable（一次性的）plastic tableware and plastic bottles. They told the school newspaper, “We do not mind spending our spare time on this meaningful public project. Once students form good recycling habits at school, they will keep doing these green things with their family members at home. Small changes at school can slowly spread to the whole community.” Even so, recycling still faces lots of real difficulties in daily life. Some people think sorting waste carefully is too troublesome（麻烦的）; others cannot clearly tell which kinds of daily rubbish can be recycled properly. Environmental experts give two practical suggestions: first, prepare separate waste bins at home for paper, glass and plastic; second, learn basic recycling knowledge through short interesting online videos in free time. These easy ways can greatly lower people’s stress of waste sorting. Environmental protection never only depends on strict government policies. Every ordinary person’s small recycling action can build a much greener and healthier living world step by step. There is no doubt that long-term environmental progress comes from millions of people’s daily small efforts. 6.  What result can we get from the study in Paragraph 1? A. Paper is harder to recycle than plastic materials B. Most families are good at sorting rubbish right now C. Recycling paper can save lots of natural resources D. Plastic waste brings more problems than paper waste 7. Why did the two students start the “Plastic-Free Campus” project? A. To make money from selling waste plastic B. To win big prizes in the school’s speech competition C. To make the school famous all over the city D. To help students develop lifelong environmentally friendly habits 8. What is one difficulty of recycling mentioned in the text? A. There are not enough recycling factories in cities B. Many people feel it troublesome to sort rubbish carefully C. Recyclable materials cost too much money to collect D. Students have no free time to join school environmental activities 9. Which piece of advice do experts give to people? A. Stop producing all kinds of plastic products at once B. Throw all waste into one big public rubbish bin outdoors C. Place different bins at home for different kinds of waste D. Leave all environmental education work only to schools 10. What can we infer from the last paragraph? A. Only governments can solve serious pollution problems B. Personal small actions are important for environmental protection C. Large public policies are useless for daily environmental protection D. People must spend lots of money to protect our living planet II.完形填空 Samelyn Lafuente, a young teacher from a primary school for girls in Masbate City, the Philippines, spent the last 11 years turning a boring classroom into a little girl's dream world, decorated(装饰) in pink and full of Hello Kitty­themed decorations.
