Although protecting wildlife may seem too hard at times, even small actions in your own neighborhood can help protect many different animals. Here are some tips on how to protect wildlife through small actions. Create wildlife-friendly areas in your backyard When trying to make your garden more beautiful, you can choose plants that can provide food and shelter for the native wildlife. This will also help cut down on pollution. Besides, bird or bat houses in your yard or garden can attract and shelter more species. Avoid harming the natural ecosystem in your backyard Some plants from other places can kill or harm the native plants that provide food and shelter for wildlife. Have a greener lifestyle By using less water and fewer fuels, you will do good to help protect the wildlife around you. Take buses or the subway if you can, turn off the electric devices when you’re not using them, take showers for a shorter time, and keep the temperature in your room at or below 68 Fahrenheit degrees in winter. Buy products that are friendly to wildlife Don’t buy products that are made from endangered animals. Keep in mind that some endangered animals are killed by traps, or hunters who are eager to earn money with them. Donate money to organizations that protect wildlife and their habitats You can give money to organizations or groups that protect wildlife in your neighborhood, thus promoting their work. 1. What’s the purpose of this passage? A. To show the threats wildlife faces. B. To raise awareness of wildlife protection. C. To explain the importance of wildlife conservation. D. To introduce different ways to protect wildlife. 2. What is suggested in the passage to create wildlife-friendly areas? A. Building a bird or bat house. B. Using less water and fewer fuels. C. Donating money to organizations. D. Buying products made from endangered animals. 3. Which of the following actions is NOT recommended for a greener lifestyle? A. Providing food and shelter for wildlife. B. Taking showers for a shorter time. C. Keeping the room temperature low in winter. D. Turning off electric devices when not in use. B Honeybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop bodies into water, they can use their wings to produce little waves and slide toward land — like surfers who create and then ride their own waves. As with many scientific advances — Isaac Newton’s apple or Benjamin Franklin’s lightning bolt — Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water. Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to limit each bee’s bodily movement, allowing close examination of their wings. They carefully studied the images captured by high-speed video cameras and found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get caught on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity. The researchers said the surf-like movement hasn’t been recorded in other insects and most semiaquatic(半水生的) insects use their legs for propulsion, which is known as water-walking. It may have evolved(进化) in bees, they predicted. Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said. 4. How do honeybees move themselves on water? A. By paddling with their legs. B. By floating with the help of wind. C. By making waves with their wings. D. By swimming with their wings. 5. How did the researchers do their study? A. They controlled and observed bees closely. B. They compared bees with other insects. C. They collected data from local ponds. D. They just used high-speed video cameras. 6. What is a potential application of the finding? A. To train bees for water rescue. B. To design air-water travel robots. C. To teach survival skills to surfers. D. To develop new types of surfboards. 7. What is the text mainly about? A. A study on the wings of the honeybees. B. The process of a scientific experiment. C. A discovery about bees’ surf-like movement. D. The evolution of insects’ swimming skills. 七选五 How to Be Eco-friendly If you’d love to be more eco-friendly but don’t know where to begin, start with a few small changes. 1 Lowering Your Energy. Turn off lights and unplug power strips(电源插板) that you’re not using. 2 Since some devices can still use energy even when they’re turned off, turn off these power strips at night to completely cut off energy use. If you need to leave your computer, or TV on, try setting it to sleep mode instead of simply leaving it on. Using public transportation. 3 Keeping cars off the road in rush hours can also improve the air quality. If you do need to drive somewhere, ask friends if they’d like to carpool(拼车), so fewer cars are on the road. 4 Say no to unnecessary plastic straws, lids, and bags and stop using plastic wrap and plastic containers for food storage. Instead, you can use reusable water bottles made of sustainable material like glass, bamboo, and ceramic. Considering growing a plant. They add more oxygen to the air, which means a less polluted air. If you don’t have a green thumb, choose some plants that are rather easy to look after. 5 If possible, grow more than one plant. A. Reduce your gas consumption and carbon emissions by walking, biking, or taking the bus. B. Here are some suggestions for you to live an eco-friendly life. C. Use less energy during the hot summer months and cold winter season. D. This is an easy way to reduce energy use. E. Using items more than once. F. Cutting Back on Plastics and Waste. G. “Lucky Bamboo” is especially good for that, since it demands nearly no attention. 语法填空 Trees are useful to man in three important 1 (way): they give him wood and other useful things, they give him cool places, 2 they help to stop drought and flood. Unluckily, in many parts of the world, man has not found that 3 third of these points is the most important. Man wants to make money from trees, so he has cut them down 4 large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless 5 (plant) and look after new trees. So the forests 6 (slow) disappear. This does not only mean that man will have fewer trees. The results are even 7 (bad): for where there are trees, their roots break up soil, allow the rain to sink in and also bind(固定) the soil, thus preventing it from 8 (wash) away easily; but where there are no trees, the rain 9 (fall) on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing 10 (leave) but useless desert. ( 1 / 6 ) 学科网（北京）股份有限公司 $ 课时作业02 Grammar and usage (Unit 1 Nature in the balance ) 01 基础练 02 提升练 03 培优练 单词拼写 1.
