①Since the first man looked up at the flying birds, countless successes have been achieved on the way up to the sky. From the stones thrown into the air to airships of all kinds, pioneers of humans never failed to let their imagination run wild.
②Stories of pioneers go back to centuries ago.
③Kite flying in China dates back to the 5th century BC and is thought to be the earliest example of man-made flight.
④From the 3rd century BC, the sky lantern (灯笼) was known in China. Many people believe that it was invented by Zhuge Liang in the war. Some say he wrote a message on a sky lantern for help, while others believe sky lanterns were used to drive the enemies away.
⑤Whichever is true, humans have never stopped, and they never will. In modern times, new fields are being explored (探索).
⑥In 1993, the world’s largest hot air airship was built. The AS-300 carried an underslung raft (悬挂式木筏). It allowed a team of French scientists to carry out their treetop researches without too much harm to the rain forest.
⑦On May 15, 2022, Chinese scientists sent up the latest model of “Jimu No.1”, China’s self-developed airship, to collect weather information on the Qinghai-Tibet Plateau.
⑧The airship would work at a world-record altitude (海拔) of 9,032 meters. It was the first time an airship of its size had reached this height, even higher than that of the 8,849-meter-tall Mount Qomolangma, the highest mountain in the world.

②Now Japanese housing developer Ichijo Komuten recently showed a “flood-resistant (抗洪) house” that can not only remain waterproof (防水) during floods but also float off the ground. He comes up with an answer to keep people’s homes from getting flooded as well as swept away by floods. Their new “flood-resistant house” was recently shown on a popular Japanese TV show and has received much attention online ever since.
③ Japan’s TV station recently visited one of Ichijo’s test sites where the company’s new flood-resistant house was being put through a flood. Although it looked just like a common house when the test began, by the time that water started rising around it, viewers could see the structure leave the ground and finally float a few inches above it.
④How does the “flood-resistant house” work? It has special vents (通风口) that close up in the event of flooding, and the plumbing (管道) also has special valves (阀门) that prevent water from getting into the home. Electrical equipment like air conditioning is positioned on the upper half of the building to make sure that water doesn’t reach it.
⑤What’s more, Ichijo’s newest invention prevents the house from being swept away. The house is connected to a number of thick iron rods (铁棒) sticking out of the ground with thick cables that ensure it stays in place as the water floods past. When the waters recede, the floating house comes back down in its own position.
⑥According to engineers, most homes flood when water reaches the window level, but because their flood-resistant house can float up to five meters above ground, water is unlikely to reach the windows, and everything else is shut. It works quite well.
1. What’s the writing purpose of this passage?| A．To introduce the flood-resistant house to people |
| B．To show the history of flood-resistant house. |
| C．To explain the importance of flood-resistant house. |
| D．To ask people offer advice on flood-resistant house |
| A．looks different from others at first |
| B．can leave the ground and float above it |

| D．can’t go back down its own place |
| A．what the flood-resistant house is like |
| B．where the flood-resistant house is shown |
| C．who invented the flood-resistant house |
| D．how the flood-resistant house works |
| A．the house cannot prevent water from getting inside |

②US company Biomason produces a new kind of concrete (混擬土) called Biolith, using bacteria that can make CaCO3. They first mixed sand and bacteria in a mould (模具), and then added nutrient solution (培养液) to keep the bacteria alive. Five days later the Biolith bricks “grew up” and were ready to use. That’s much faster than producing traditional concrete, which requires about 28 days.
③According to the company, this method can greatly cut down carbon emissions in the building industry. Traditional concrete is made of small stones. The stones are heated to temperatures greater than 1, 300°C, during which carbon dioxide comes out. A company, McKinsey & Company, reported that the concrete production industry accounts for 4.5 percent of global greenhouse gas emissions.
④Biolith, however, doesn’t need heating so it’s more environmentally friendly. The company plans to reduce 25 percent of carbon emissions from the concrete industry by 2030.
⑤There are other similar technologies, but they are not in production yet. The University of Colorado in the US is studying a living, recyclable building material using cyanobacteria (蓝藻细菌). It can use CO2 and sunlight to grow and help get carbon. NASA is trying to grow buildings out of fungi (菌类) on the Moon and Mars, which may lead to more sustainable ways of living on the Earth.
1. What are the steps of making Biolith?a. Put the mixture in a mould. b. The bricks grow up.
c. Add nutrient solution. d. Mix sand and bacteria.
| A．abcd | B．aedb | C．dcab | D．dacb |
| A．Because the growth of Biolith is faster. |
| B．Because Biolith doesn’t have the process of heating. |

【推荐3】If you look around the room you are in right now, you’ll probably notice a number of electronics. But can you imagine if they all had to be joined together by wires (电线)? Picture the wire snaking along the floor, for example, from your smartphone to your speaker, or connecting your game controller to the computer screen, meaning you could never sit more than a couple of meters away from it. A world of electronics connected by wires wouldn’t just be untidy, but a possible danger, too. That’s where Bluetooth comes in. We’ve all heard of it — but what exactly is it?
Bluetooth is a method of short-distance (短距离) wireless communication between electronics that makes use of the power of radio waves. The idea was first thought of by Dr. Janp Haartsen at Swedish mobile company Ericsson in 1994. Things really stepped up in September 1998 when the Bluetooth Special Interest Group (SIG) was set up to develop and spread the technology. Bluetooth 1.0 came out in 1999, and a year later it began to be used in mobile phones and desktop computers. Now Bluetooth has become an increasingly popular way of solving the problem of more and more electronics needing to be connected. without having to connect everything together with wires.
But if you look at the remote control (温控器) you use to choose the program on TV, you might rightly ask yourself why Bluetooth was such a big deal. After all, connecting objects with infrared signals (红外信号) which can’t be seen had been done before. The problem with remote controls is that they need to keep what is called “line of sight”. If something is standing between the remote control and receiver, it won’t work. Because Bluetooth uses radio waves, the things standing in the way are no longer a problem.
Since its creation in the late 1990s, the technology has become more and more improved and widely used, with the 4 billionth Bluetooth objects shipped in 2020.

【推荐3】Researchers at China Aerospace Science and Industry Corp, a State-owned defense contractor, have developed and made the world’s first robot whale shark (鲸鲨). The robotic shark has been on display in an aquarium (水族馆) at Shanghai Haichang Ocean Park since January.
A whale shark is a slow-moving carpet shark and the largest known living fish. Designed and built by engineers at the Shenyang-based No. 111 Factory, the underwater robot is 4.7 meters long, weighs 350 kilograms and can move 42 meters a minute.
Powered by a lithium battery, it can swim, turn, float and dive like a real shark by moving its mechanical fins (鳍). The mouth and gills (鳃) can also open and close like a shark’s. The biomimetic shark is made of sensors (传感器), multi-joint fins, batteries, and systems which enable it to avoid what’s in the way in all directions. “The robot can reach a depth of 10 meters and work for as long as 10 hours,” said Fang Xuelin, a senior researcher in charge of the robot shark program. “The shark can be remotely controlled and can also swim based on preset programs or its own sensors,” he said.
“We have built multiple kinds of robot fishes ... the robotic whale shark is the largest mechanical fish we have made so far,” Fang added. “Our robots are to serve three purposes — to perform in aquariums for entertainment, spread knowledge about the sea and aquatic (水生的) animals among youngsters, and carry out scientific tasks such as hydrological surveys, underwater photography and environmental inspection.” “The factory now plans to develop more types of aquatic robots, including some extinct mammals (哺乳动物), for display in parks and schools. It will also promote the products to businesses engaged in fields such as underwater salvage and mineral prospecting,” he said.

【推荐1】①You get up in the morning and suddenly you feel that you have a big stomachache. And you also feel sick and want to vomit (呕吐) very much. If so, maybe you’ve got stomach flu.
②Stomach flu is one of the most uncomfortable common diseases. It spreads easily, which can make it hard to avoid. That’s especially true if someone in your family has it. Stomach flu is caused by a virus, but not the same one that causes common flu. There’s no medicine to make it go away at once. But there are some things you can do to avoid catching it.
③You can prevent stomach flu by washing your hands often. Use hot water and soap to wash your hands. Using soap is better than using nothing, but it doesn’t work very well against stomach flu. That’s because soap can’t kill viruses completely.
④The virus that causes stomach flu is hard to kill. So stronger cleaners (清洁剂) are needed. Mix bleach (漂白剂) with water, and use that to clean your house. If someone in your family is sick, remember to clean the things the person has touched.
⑤Machines like dishwashers and washing machines are better at killing viruses than washing by hand. That’s because they keep the things you wash hotter for longer. But many viruses can live in your machines, so often wash them with hot water and bleach.
⑥However, if you do get stomach flu unluckily, don’t worry. Have a good rest and drink as much water as possible, and you’ll feel much better soon. But don’t think everything is OK. Even though you feel better, ▲ . You can still spread it for a few days, so you need to stay at home for some more time. If you have a fever, wait at least 24 hours after it ends before going out. This will help protect other people from getting sick.

| Raisins are grapes! Raisins are nothing but dried grapes. Do you know how to make raisins at home? Here is an easy way to make raisins at home. You can do it with your parents on a summer afternoon.
● some seedless grapes ● one clean plate or a dish ● a piece of clean cloth Step ●Remove (移除) the pedicels. ●Wash the grapes. To have the bright and fresh color of the grapes after you dry them, add a little lime juice (青柠汁) to the water when washing. ●Dry the grapes with the cloth. Or simply let them sit for some time until the water runs out. ●Put them in the dish and set the dish in a dry sunny place. If the weather gets cold and rainy at night, you can get the plate inside the house for the night and then place it out in the morning.
Don’t cover the dish. Check it each day for two weeks.
The water inside each grape moves through the skin of the grapes and goes into the air and disappears. So the wet grapes slowly dry out and turn into raisins.

A bike road in Krommenie, a city in the Netherlands, isn't just helping people get around--it's also producing energy. The road, named SolaRoad, is paved with solar batteries, which use the power of the sun to make electricity.
The project is created to show that the places where people ride, walk, or drive can also serve to produce energy. And the solar-powered road is doing a better job than expected. So far, it has created enough electricity to power three houses for a year.
Many cities already cover rooftops with solar panels（面板）. By using renewable sources of energy, cities can decrease their dependence on fuels, coal, oil, and natural gas. Renewable sources of energy don't get used up or create pollution as fuels do.
Roads can provide even larger space than roofs to harvest energy from the sun. Sten de Wit, one of the researchers behind SolaRoad, says, “In the Netherlands, we have about 140,000 kilometers of roads. It's a huge area, more than all of the rooftops combined."
To create the experimental bike road, the SolaRoad team lay down concrete slabs（混凝土板） with rows of solar batteries on. A layer of strong glass covers and protects the batteries. Sunlight passes through the glass and into the batteries, which turn the sunlight into electrical energy.
Although the bike road is expensive to build, with the energy it produces, it could pay for itself within 15 years. By building solar-powered bike roads, cities could produce enough energy to power street lamps, traffic lights, and even electric cars. Most people don't notice that the bike road is different from a traditional street. Sten de Wit says, “That is exactly what we want: it does whatever it has to do to be a proper road while harvesting solar energy at the same time."
1. What does “it” in Paragraph 2 refer to?| A．the project | B．energy | C．the solar-powered road | D．a better job |
| A．can be used once | B．never be used before |
| C．can be easily replaced | D．able to be made again |
| A．It uses the power of the sun to make electricity |
| B．Netherlands has about 140,000 kilometers of SolaRoad. |
| C．There is a layer of strong glass on it. |
| D．It is doing a better job than people expected. |
| A．the solar-powered bike road is worth building |
| B．the SolaRoad could produce enough electricity for the whole city |
| C．the SolaRoad looks different from the traditional road |
| D．most cities can’t afford to build the solar-powered bike road |
| A．New solar batteries take the place of traditional solar panels |
| B．The advantages of using renewable resources in cities |

【推荐1】Ten years ago, I set out to study luck. I wanted to know why some people are always in the right place at the right time, while others are always unlucky.
Many people volunteered for my research. Over the years I interviewed them, watched their lives and had them take part in my experiments.
I carried out a simple experiment to discover why there were differences in their ability(能力) to spot opportunities. I gave both lucky and unlucky people a newspaper and asked them to look through it and tell me how many photographs were inside.
I had secretly placed a large message halfway through the newspaper saying, “Tell the researcher you have seen this and win $50.”
This message took up half of the page and was more than two inches high. It was staring everyone straight in the face, but unlucky people tended to miss it and lucky people tended to spot it.
Unlucky people are just more nervous than lucky people. They are busy looking only for what they need and this stops them from noticing the unexpected. As a result, they miss out on opportunities.
Lucky people tend to be more relaxed and open. They can see everything that is in front of them, rather than just what they are looking for.
My research shows that lucky people live by several principles(原则). Here are some of these principles:
Listen to your gut instincts(直觉) — they are often right.
Be open to new experiences and break your normal thought patterns(模式).
Spend a few moments each day remembering things that went well.
See yourself being lucky before an important meeting or phone call.

【推荐2】This is a letter from Anthony Morris, a professor at Robert Morris University. He shares his thoughts on the three taikonauts (astronauts) of the Shenzhou-13 spaceship who completed their space travel started from October 16, 2021.
It was Friday in my country. I watched the red-and-white balloon（气球）slowly return to the Earth from half a world away. It was a beautiful Saturday morning in Asia, and the perfect weather allowed the world to enjoy what was happening. The balloon was carrying three taikonauts home after their successful six-month stay in space.
As Zhai Zhigang, Ye Guangfu and Wang Yaping safely landed in China’s Inner Mongolia on April 16, 2022. I thought of what we Americans must have felt on July 21, 1969 when Neil Armstrong and his coworkers touched down on Moon.
Now, the taikonauts will be witen about often and excitedly in the future. The U. S. and Russia have played roles in space discovery for years, and now China has become an important player and made ongoing efforts.
Perhaps the most meaningful mission（任务）took place on November 7, 2021. Wang Yaping became the first woman taikonaut to take a spacewalk, which lasted over six hours. After successfully returning to Earth, Wang Yaping handed astarto her daughter. It likely passes a message to Chinese boys and girls: You, too can reach for the stars, and it’s possible you will reach them. And because of her bravery, more women taikonauts would join the similar activities in the future.
Surely, Zhai, Ye and Wang are heroes, because they had spent the longest time in space. And there are even more Chinese heroes（英雄）to come. In China, you are heroes. And for me, I also think of you as heroes.
