Ramp The Great Pyramid of Giza was the tallest structure in the world, built around 2580 BC, with a history of about 4,600 years.How were the stones of it lifted up? People cut the big stones on the ground.Then they pushed them up ramps.It took about twenty years to build the Great Pyramid.Today we use cranes (起重机)to lift building materials.And we can build tall buildings in less than one year. Lever Archimedes, an ancient Greek who did well in maths, was the first person to describe a lever in around 260 BC.Levers help us lift heavy objects.People think the builders in ancient Egypt used levers to move stones.Today many of the tools we use are levers, like chopsticks and scissors. Screw Screws were first used in Greece.In ancient times, screws were used to move heavy objects by rotating them around in a circle.Today we use screws to hold things in places. 1.(　　)How were the stones of the Great Pyramid of Giza lifted up? A.By using levers. B.By using screws. C.By using ramps. D.By using cranes. 2.(　　)Which of the following belongs to levers according to the text? a.scissors b.chopsticks c.screws d.cranes A.a, c B.b, d C.a, b D.b, c 3.(　　)What does the underlined word “rotating” probably mean in the text? A.Breaking. B.Turning. C.Cutting. D.Pushing. B Plants can not move like animals, but they communicate and respond to the environment through their own movement—a type of “plant body language”.Scientists have been amazed by these movements and created inventions based on them. Everyone knows sunflowers turn to face the sun as it moves across the sky.This gave engineers the idea to create SmartFlower solar panels.They are in the shape of flowers, and each “petal(花瓣)” is a solar panel.SmartFlower follows the sun all day, which helps produce 40% more energy than normal solar panels.After dark or when there’s bad weather like heavy rain, the “petals” will close up. Some plants, such as ivy (常春藤), can climb walls using sticky pads.The pads help ivy stick to wood, stone, and other surfaces.After studying this plant, scientists created soft climbing robots.Though small, these robots are strong enough to move on different surfaces and turn corners.This allows them to work in hard-to-reach places. Another amazing plant is the exploding cucumber (喷瓜).It has a cool trick.When touched, it shoots seeds up to 6 metres away! Learning from this plant’s “body language”, medical researchers have developed a new way to send medicine to where it’s needed in the body, just as the plants shoot seeds to the right places. Plants may seem quiet and still, but their special movements have inspired real-world inventions.Next time you see a plant, watch its “body language” carefully; you might catch the next scientific breakthrough! 4.(　　)Which picture best describes the invention in Paragraph 2? A. B. C. D. 5.(　　)Where is the climbing robot designed to operate? A.Deep under water. B.Wide farm fields. C.Narrow water pipes. D.Open playgrounds. 6.(　　)What is special about the exploding cucumber? A.It can play tricks on others. B.It can send out the seeds far. C.It helps people make medicine. D.It can grow up to 6 metres tall. C Paper is one of the basic products of the modern world.From books to toilet paper, everyone uses paper in daily life. According to a report, 40% of the 15 billion trees felled (砍伐)are used to produce paper every year.More importantly, the paper-making process uses lots of water and causes air pollution. This is where Releaf Paper comes in.The company has found an ingenious way to make environmentally friendly paper.Instead of using wood to make paper, it uses leaves.The company was set up by Valentyn Frechka.He has always been interested in biochemistry (生物化学), which led him to try making paper from grass.When that failed, he moved on to leaves and achieved success. 　 ▲　 Some European cities collect leaves from their streets and send them to Releaf Paper.Then, using mechanical (机械的)and chemical processes, the company is able to create one ton of cellulose (纤维素)from 2.3 tons of leaves.Cellulose is the material that paper is made from.Lignin (木质素), the leftover (残留物)from the processes, is then sent back to the cities to be used as fertilizer (化肥).The new processes use 15 times less water and cause less air pollution than the traditional paper producing model. “We are working only with the leaves that we get from cities because we cannot use the leaves from the forest.It’s not easy to collect them in the forest, and there is no need because there is an ecosystem,” Frechka said.“We get leaves for making paper and return lignin to the cities.It’s like a win-win model.” 7.(　　)What do the numbers in Paragraph 2 suggest? A.There are fewer trees around the world. B.Making paper has caused serious air pollution. C.A large number of trees are used for making paper.D.The total number of trees on Earth is 15 billion. 8.(　　)Which sentence can be put in 　 ▲　? A.So how is the paper produced? B.What can people do with waste? C.Why did Frechka start Releaf Paper? D.Why is producing eco-friendly paper important? 9.(　　)How does Releaf Paper make environmentally friendly paper? A.By moving to a new location. B.By using a different material. C.By inventing greener machines. D.By collecting leaves in the forest. 10.(　　)What do we know about lignin? A.It’s a kind of harmful waste. B.It can be used in city gardens. C.It can be used to make paper. D.It can be used to create cellulose. D When we touch something with our fingers, we can feel how warm or cold it is.However, most wearers of prosthetic hands (假手)can’t feel it.To change that, a group of scientists in Switzerland have developed the “MiniTouch”. The MiniTouch can be easily paired with a prosthetic hand.The wearer of the hand can then use it.Firstly, it collects thermal (热的)information from the index finger (食指)of the hand.The information is then sent to the nerves (神经)that were once connected to the missing hand.This can help the wearer to sense temperature in daily life. Fabrizio was the first to try out the MiniTouch.The Italian man is 57 years old.He lost his right hand 37 years ago.For one test, the team prepared three similar bottles.They were filled with cold (12℃), cool (24℃)or hot (40℃)water.With the help of the MiniTouch, Fabrizio could quickly tell the difference and didn’t make any mistakes.Without it, he only got 33% right.In another test, he sorted steel blocks according to their temperatures.The MiniTouch helped him to get 75% right. The scientists’ next step is to improve their device (装置；设备).They want it to be able to sense touch as well.In this way, it will tell the user “this is soft and hot” or “this is hard and cold”.Another goal is to make the MiniTouch able to collect thermal information from four other fingers.“It’s all about giving the wearer a richer, more natural sense of the world,” said Micera, one of the scientists. 11.(　　)Why did the scientists develop the MiniTouch? A.To touch something. B.To cure the disease. C.To help the disabled. D.To change prosthetic hands. 12.(　　)How does the MiniTouch work? ①The wearer senses the temperature. ②The MiniTouch collects information. ③The MiniTouch is paired with a prosthetic hand. ④The index finger sends information. A.②③④① B.②①③④ C.③①②④ D.③②④① 13.(　　)What does the underlined word “it” refer to in Paragraph 3? A.His right hand. B.Cold water. C.The MiniTouch. D.The temperature. 14.(　　)What do we know about Fabrizio? A.Fabrizio comes from Switzerland. B.He had two tests about the MiniTouch. C.He lost his hands at the age of 20. D.He could sort steel blocks by himself. 15.(　　)What is the goal of the future MiniTouch? A.To help the wearers to have more money. B.To use five fingers to collect information. C.To tell the sense of sight by using it. D.To offer the users a richer, more natural sense of the world. 四、阅读表达。 阅读下面短文，简略回答问题。 In our daily lives, we often keep electrical appliances (电器)plugged in (接上电源)even though we don’t use them.This small habit can waste a lot of energy.But this problem can be solved by smart plugs! A smart plug is a small thing that you can connect between your wall socket (插座)and any electrical appliance, like a TV, a computer, or a light.It’s really easy to use; with the help of an app on the phone, you can control the power of the plugged-in electrical appliances anywhere.For example, if you forget to turn off the lights before leaving home, you can just use the app to turn them off. One of the best things about smart plugs is that they can detect when an electrical appliance is not in use but still connected.When you’re not using your game box but it’s still plugged in, the smart plug can cut off the power, so no energy is wasted. Using smart plugs can save a lot of electricity.In fact, studies show that a family can save up to 10% on their electricity bill each month by using smart plugs.This not only helps you save money but also reduces the need to produce more electricity, which is good for the environment. Smart plugs also have some problems.They are much more expensive than normal ones.Also, they need a stable (稳定的)internet connection.If the Wi-Fi is poor, they may not work well. In a word, smart plugs are simple and useful.They make our lives more energy-efficient (高能效的).Using smart plugs is a small step towards a greener future. 1.How can you control a smart plug? ____________________________________________________________________ 2.What can a smart plug do when an appliance is not in use but still plugged in? ____________________________________________________________________ 3.How much can a family save on their electricity bill each month by using smart plugs? ____________________________________________________________________ 4.What problem do smart plugs have?
