Increasingly, engineers are saying that robots are going to move out of research departments and into your home. Companies including Sony and General Electric are working on designs for small robots. Products like the Roomba, a robot that can clean floors, are flying off the shelves.
What’s behind this new robot revolution? It’s partly a matter of technology. Devices that can recognize and respond to a human voice have been developed. There are now a few different ways for robots to move around. They can walk, crawl or ride on wheels. Robots are being made smaller and smaller. They are also becoming more and more energy efficient.
A bigger part of the story is on the demand side. From the day the television remote control was invented, people around the world have searched for new ways to be lazy. Take into consideration that more and more people can afford robots, and the time seems ripe to introduce robots to the average family.
To be sure, robots that walk on two legs and talk like people are still a long way off. However, robots that do basic housework such as cleaning or gardening are sure to come out soon. One thing is certain---when these robots do come to our homes, it will change things forever.
1. According to the passage, robots can do the following things EXCEPT________.
A.cleaning floors | B.making cars | C.talking like people | D.making computers |
A.Smaller robots are less energy efficient. | B.Roomba has been out of date |

【推荐1】If you are a fan of J.K Rowling and her Harry Potter books, you must be interested in the idea of the invisible(隐形的) coat. You are not alone. Scientists have been working hard to produce a material which will make buildings as well as people invisible.
A Canadian company said that they had made a special cloth. It was called “Quanturm Stealth”. The company said that the material could make its wearers completely invisible, even to people with night glasses. Also, just like Harry Potter’s coat, it is light-weight and does not need cameras, batteries, lights or mirrors to work, and it does no harm(危害) to the environment. But best of all, it is cheap to make.
So how does it really work? Well, that is a top secret. The company only explains that they have successfully found ways to bend light waves(弯曲光波) so that they go around the material instead of through it.
To show that Quanturm Stealth is real, the company has given photos and even a video showing its special coat. Both the US and Canadian governments have seen the coat. And the company is now working with Hyperstealth Technology to improve the cloth and try to make soldiers(士兵) invisible all at once! Then people have only one question —When will the rest of us can get this special cloth? As for this, the company has its own idea.

【推荐2】How will the Internet change the world? Will we enjoy a smarter life in the future? Recently, many of the world’s biggest Internet companies took part in an important meeting. They talked about how to build a future for our online world. The Internet can make our lives easier in many ways. The companies at the meeting showed us some of their latest technology. Here are some examples. Let’s take a look.
Lip reading machines
They can not only read faces. They can also read your lip movements. The Chinese Internet company Sogou has made lip reading technology. You don’t need to speak aloud. The machine turns your lip movements into voice or text. This could be very useful if you are in a noisy place and people cannot hear you on your phone. Police can also use this technology. Sometimes they see criminals on city-monitoring cameras, but they don’t know what they say. The lip reading technology can help people with this.
Smart shoes
Your feet might hurt if your shoes don’t fit you. This won’t happen if you wear “smart” custom-made shoes. The Xiemofang company brought a machine to the meeting. The machine scans your feet. It records 39 parts of your feet. It also has a database (数据库). The database has more than 10,000 kinds of shoes. You can choose the colour and style. It also gives you suggestions for your choices. The suggestions are based on records of other people’s feet. You can get your new shoes after 10 days.
Unmanned supermarkets
You walk into a supermarket, pick out your goods and go to check out. But there is no worker. There is just a tablet (牌子) that says “Please smile”. When you smile, it gives you a discount (打折). Your money goes from your Alipay account to the supermarket. You don’t need to do anything. The Alibaba company has made this supermarket. When you go into the supermarket, it knows your face and your Alipay account. It also knows your facial expressions. So it knows how much you like your goods. The supermarket not only makes shopping easier, but also comprehends you.

【推荐3】Earlier this year, students from a school in Zhejiang Province won many prizes at the 12th BeiDou-Cup China Adolescents Science and Technology Invention Contest (BD-CASTIC “北斗杯”全国青少年科技创新大赛).
BD-CASTIC was started in 2010 by the Chinese government. The competition is held to encourage students to learn more about navigation (导航) technology. Students from Shaoxing No.1 High School took home nine awards, including two first place prizes, four second place prizes and three third place prizes.
One of the first place prizes went to a smart system (系统) for safe driving built by Qian Weicheng and his team. “As more cars run on the road, the number of accidents has increased. Things will be worse if more driverless cars are allowed on the road in the future,” Qian said, “So we wanted to develop a system to lower the risks.” It can check real-time safety distances (距离), watch over the temperature inside the car and look for other problems such as drunk driving.
Zhang Yantao and his team invented a smart robot to help stop the spread of COVID-19. The robot can carry out tasks such as taking people’s temperature and giving out medicine so that doctors and COVID-19 patients can avoid face-to-face communication. The team won the second prize for their invention.
Both of their inventions are based on BeiDou Navigation System (BDS). To complete their inventions, they needed to learn the knowledge of BDS, which they got from their “BeiDou class”. Right now, the class is the only one set up in the middle school around the country to get more talents prepared for the future development of BeiDou science and technology. Over 170 students have joined the program. “We hope the program will develop students’ creative spirit by pointing out and solving problems,” said Zhou Wenlong, the program leader.

【推荐1】Facial recognition technology (人脸识别技术) is widely used today. For example, the police use it to search for bad guys. It’s also used to unlock phones or doors.
Now, a similar technology, known as facial detection (探测), is entering a new field: the business of advertising (广告).
Such systems are going through tests in a small number of stores. One facial detection system can judge (判断) a person’s “happiness” or “fear” level. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people’s ages and five levels of feelings — from “very happy” to “very unhappy”.
Supporters of the technology say it could improve buyers’ experience by showing products they might like or by offering them products at lower prices.
Some are against the idea of using such systems. Pam Dixon, the head of a privacy (隐私) group, is one of them. She thinks ________. For example, a store could raise the price of a product according to a person’s age and feelings.
However, one store testing the technology explained people’s information like names or ages wouldn’t be stored. And the advertising board system maker said it didn’t keep any personal information or record any videos.
1. Facial detection technology can judge people’s ________, according to the passage.A.weight | B.feelings | C.height | D.hobbies |

【推荐2】As you probably know, clothing has been around since the time of Adam and Eve—and it’s become a lot more complicated than those early fig leaf designs. On the other hand, electronics have been with us for only a few hundred years—beginning with Franklin running round with his portable lightning rod. With gadgets(小电子产 品)more popular than ever these days, digital fashion, a combination of clothing and electronics, is simply inevitable.
First let me mention a line of jackets launched in the fall of 2013 by Royal Philips’ Electronics and Levis Strauss Corporation. Philip’s original press release called it “mixing fashion and technology in the creation of work wear for the digital age”. I love that kind of talk. Each design is said to contain a simple body area network using wires placed into various parts of the jacket. What it really does is allow one to use a Philips’ GSM mobile phone and MP3 player in the jacket—all controlled by a unified remote.
A company named Vivo Metrics has designed a different type of electronic garment. It’s called Lifeshirt, and it’s an ambulatory monitoring system stuffed into a flexible, washable T-shirt. Vivo Metrics has built a system that allows doctors to monitor more than 40 physiological signs(heart rate, breathing rate, blood pressure, etc.)over extended periods of time. With that a man who suffers from sleep apnea (呼吸暂停)can send the medical data to his doctor on a regular basis. But this product is not available to customers, as it’s intended for clinical and medical research.
I believe these products are only the tip of the iceberg. More of them will find their way to our future life, making a difference by combining computer technologies with clothing design.
1. Why are Adam, Eve and Franklin mentioned in the first paragraph?A.They can tell the origin of digital fashion. |
B.They can show a long history of clothing and electronics. |
C.They can prove that clothing came before electronics. |
D.They can lead in the subject of the whole passage. |

A.It has saved thousands of people’s lives. |
B.It works similarly as the digital jacket does. |
C.It has not really benefited the patients yet. |
D.It has collected a great deal of data for doctors. |

NASA(美国航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.
At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.
The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.
Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(细菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.

【推荐1】Every year on 15th October, over 200 million people around the world take part in Global Handwashing Day. But why do we have a day for something we do all the time? Well, research shows that not enough people often wash their hands with soap. Experts believe that this leads to the deaths of millions of people every year.
Sidibe, a public health expert says soap is “the most beautiful invention in public health”. Washing your hands with soap can have a huge impact on reducing (减少) the spread of diseases. Handwashing with soap prevents babies from getting ill and keeps children healthy in school.
However, washing hands with soap does not happen as often as you might think. This is partly because there aren’t enough resources (资源) in poorer countries, but it’s also because for many people, handwashing is simply not part of their everyday life. It’s not easy to get people to change habits they learned in early childhood—but this is what Global Handwashing Day wants to do.
In 2008, the Indian cricket team joined around 100 million Indian schoolchildren in washing their hands to promote (促进) the first ever Global Handwashing Day. Every year since then, many different events have been held around the world. In 2014, Global Handwashing Day was used in the fight against Ebola, a very serious disease, with events held in affected (受感染的) African countries.
Today, local and national leaders continue to use the day to spread the message about the importance of clean hands. The hope is that handwashing becomes a necessary part of people’s lives and improves the health of millions around the world.

【推荐3】It was a rainy day. I didn’t feel like driving up the winding mountain road to my daughter’s house. But she kept asking me to come to see something at the top of the mountain.
So here I was, although the two-hour journey was full of fog and rain. After lunch, my daughter requested me to drive her to Barage. After a ten-minute drive, we parked the car and got out. We walked along a road that was thick with old pine needles (松针). Huge evergreens towered over us. Gradually the peace and silence of the place began to fill my mind. Then we stopped because I was in great amazement.
Looking down from the top of the mountain, there were rivers of daffodils in amazing colors. At the center hung a waterfall of purple hyacinths (风信子). Here and there were beautiful tulips (郁金香). The scenery is like a picture of the nature.
A lot of questions filled my mind. Who created such beauty? Why? How?
As we were on the way home, we saw a sign that read, “Answers to the Questions I Know You Are Asking.” The first answer was: “One Woman — Two Hands, Two Feet, and Very Little Brain.” The second was: “One at a Time.” The third: “Started in 1958.”
I was so moved by what we had seen. “She changed the world,” I said, not getting over the shock, “one bulb (球茎) at a time. She started almost 40 years ago, probably just the beginning of an idea, but she kept at it.”
“Imagine,” I added, “if I had a dream and worked at it, just a little bit every day, what might I have achieved?”
My daughter looked sideways at me, smiling. “Start tomorrow,” she said. “Better yet, start today.”

【推荐1】Shameem was born in a small village in Pakistan. In her village, it was a tradition to keep girls inside their homes. They were not allowed to get an education.
Fortunately, Shameem’s uncle, a university teacher, wanted to give her a chance to see the world. He offered Shameem a chance to attend school. So she became the only girl student in her class.
However, Shameem struggled to complete her schooling. To get permission for college, she went to a three-day hunger strike(抗议). After graduating from college, Shameem got a position in a non-profit organization(非营利性组织) working to help women in rural( 农村的) areas.
There, she saw a Pakistan that she didn’t know. Until then, she thought she had a difficult life. But there, she saw what women in other parts of Pakistan were experiencing. Some women had 11 children, but nothing to feed them. They would walk three hours every day to get water.
Shameem found that the position was more than just a job for her. She discovered her power. By setting an example, her experience could encourage more people to understand the importance of education and send their daughters to school.
Now, Shameem teaches in a rural school in her hometown. “The first day I walked into the school,” she said, “I saw all these little Shameems staring at me with dreams in their eyes, the same dream of freedom which I had in my childhood.”
Today, there is not a single girl in her village who doesn’t go to school.

② A team at RMIT University in Melbourne, Australia, found a way to put special nanostructuresinto clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains (污渍) that don’t belong on your clothes.
③ The nanostructures don’t break down the actual clothing because cotton and the other clothing materials are too strong to be broken down. According to CNN, the researchers cover the clothing in a solution made of silver and copper (铜) nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new.
④ So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment.
⑤ According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done.
⑥ “There’s more work to do before we can start throwing out our washing machines,” said Dr Rajesh Ramanathan, “but this is a strong foundation (基础).”
⑦ So what’s the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat the clothing with the solution while clothes are being made.

Lightning can also be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches temperatures up to 28,000 degrees centigrade. American Roy Sullivan, who worked in a park, holds the record for surviving the most lightning strikes. Between 1942 and 1983, he was hit seven times!
So, why does lightning strike? Lightning strikes happen when ice and water in clouds rub(摩擦)together, and cause atmospheric(大气层的)changes. When this happens, it creates a static charge(静电电荷). Lightning can strike inside the cloud, between two clouds and between a cloud and Earth. It’s the last type of strike that is the most dangerous for humans. About 1,000 people get struck by lightning every year in the United States, and about 100 of them die as a result.
Lightning is certainly not something
