Can humans and machines “talk” to each other? We often see this in movies and on TV shows. In the 1960s, in the TV series Star Trek, spaceships could reply to human voice orders. In 1968, in the film 2001: A Space Odyssey, HAL 9000 is a computer that human can talk to, it can play chess with humans and fix their spaceship. This type of technology, which help machines understand human speech and act accordingly, is known as voice control, or voice recognition.
Today, voice recognition is not just shown on the screen, but is widely used for everyday tasks. Siri and Alexa, the voice recognition software made by Apple and Amazon, are two examples. You can ask it to do many things, from setting alarms to turning on the television and placing online shopping order.
One of the nice things about voice recognition is that it can be used when we’re on the go. When you’re driving a car or walking down the sidewalk, it can be not easy or even dangerous to pick up your smartphone and type away on the keyboard. With voice recognition, you can focus on whatever you’re doing at the moment while still finishing other tasks.
People with hearing problems can also benefit. Speech recognition can be used to listen to spoken words and turn them into text that deaf people can read. Advanced speech recognition software can even hear words spoken in one language and then translate it into another language.
As voice recognition software becomes more advanced, it will be able to help us in even more ways. So far, most voice recognition technology is not able to recognize specific voices. That is to say, your voice “sounds” the same to the software as your friend’s voice. However, Apple and other companies are already working to develop voice recognition software that replies only to specific voices.
How would this be useful? It could make your things safer. You could set your phone, computer or even other things like your car or home to open only when they hear your voice.

【推荐1】Fifty-two-year-old American Henry Evans is one of the world’s first teletourists (远程游客). Henry has travelled to different places all over the world. Under normal environment, this journey would be impossible for him because he is disabled. A serious illness when he was 40 influenced his brain and left him without speech and unable to use his arms or legs. But with the help of technology, Henry is able to overcome his difficulties and get out to see the world.
When Henry wants to visit a museum, he uses a robot called the Beam, a big computer monitor (监视器). Using head movements, he can drive the machine around the halls, talking to the guide just like any other visitor. Several world’s museums already use these machines, and Henry hopes there will soon be more.
To see what is happening outside, Henry uses a tool called Polly. Polly is made up of a monitor and a camera. He controls it by moving his head, so that it turns around and shows him everything his partners can see and hear.
Thanks to technology, Henry can fly drones (无人机) which also enable him to search for something from the air. When he wants to go further a field, he has found a website which has 5,000 drone videos from all over the world. These give him a chance to all kinds of attractive places.
No journey is too far for Henry, who is currently creating the possibility of travelling into space. He got the idea from an article he came across on the Internet. He read that a research team was trying to get access (使用权) for PC users to a robot on the International Space Station.

【推荐2】When were the cameras invented? Let’s go into the past. In the 1500s, men made experiments (试验) on cameras that made images. But it was not until the early 1800s that someone found a way to make the pictures permanent (永久的). Then photography was a new technology. Most families couldn’t take pictures themselves. They would turn to a photographer. People didn’t have their own cameras because it was too difficult to take pictures and develop the film (冲洗胶片).
In 1884, George Eastman invented a kind of film that fitted back to a small camera to change photography and the new film was easy to use for many people, so they began to buy cameras. When they had used up (用完) their films, people sent their cameras back to the factory. The film was developed in the factory and helped print pictures. Then more and more people could use the cameras and film.
Eastman’s invention made it easy to take photos. Today’s cameras are even easier to use and people can put in films themselves. Taking photo has become a growing hobby.
There are also many new jobs in the field such as newspapers, magazines and televisions. They all need pictures to tell their stories well. With the help of photographers, scientists can take pictures through microscopes (显微镜) and telescopes (望远镜). Deep-sea divers take pictures of ocean plants and animals, while astronauts take their cameras into space.

【推荐1】In almost all electronic products, there will be chips(芯片) supporting their functions. Chips are also known as integrated circuits(IC) (集成电路).
On April 22, 2021, Tsinghua University announced that its School for Integrated Circuits was set up. Its purpose is to train talents for the country’s IC industry and make local Chinese chips.
IC is key to the development of the information technology industry. However, because of the low technical level in IC development, for a long time, China has had to depend on other countries that are more developed in these areas.
So the move of building Tsinghua new school comes at a good time, reported Caixin Global. A director of this industry told the Global Times that more schools like Tsinghua University’s new school are likely to be set up.
“For students, IC can be an interesting area to explore in the future,” Zhang Yong, a computer engineer from an IC company in Beijing said.
A.They are the hearts and brains of electronic products. |
B.He explained that making a chip is like building a house. |
C.This has made the area a goal for bullying (打压) by the West. |
D.The reason is that China is going full speed ahead in its industrial development. |
E.The world is developing fast with the rapid development of science and technology. |
F.The new school will be the first in China to offer a specific major (专业) in the subject. |
【推荐2】How do people find their ways? At first, people did it by looking at the sun, the moon and stars. Later, we started to use the compass(指南针).Today, there are navigation satellite systems(卫星导航系统).
A navigation satellite system uses groups of satellites(卫星), they send information to a receiver, such as your smart phone. Then they can find where you are.
The earliest navigation system is the Global Positioning System(GPS)(全球定位系统) of the United States. The US has put 24 satellites into space to make sure GPS can locate a person correctly and globally. Russia's GLONASS and European Union's Galileo can also work globally.
The BeiDou Navigation Satellite System (BDS) is China's homegrown navigation system. It was set up in 2000. On June 23rd 2020, the last satellite of China’s Beidou Navigation Satellite system was sent into space. Beidou, China’s own navigation system, was finally completed. On July 31, Beidou started providing full-scale global services(全面的全球服务). More than 120 countries and regions (地区) are now using Beidou services. Since 2000, China has sent 55 Beidou satellites.
BeiDou can find you wherever you are. It helps you go faster by finding shortcuts and using correct directions. When you are in trouble and call the police, they will know exactly where you are if you have a smart phone that uses BeiDou.
BeiDou also has a unique messaging ability. It allows people to send text messages up to 1,200 Chinese words when mobile phone services are interrupted(中断) because of some reasons.

【推荐3】Historically, most cars have run on gasoline(汽油), but that may change in the future: cars can also run on other liquid fuels(液体燃料) and electricity.
Gasoline is from oil. The energy in gasoline comes from hydrocarbons(碳氢化合物). Gasoline provides great power for cars. However, it causes environmental problems, like air pollution and temperature rise. So gasoline can’t be the best fuel.
Another choice is electricity. Electricity cars can be as efficient(效能好的) as cars using gasoline, and they produce less pollution. But electric cars themselves are more expensive. Good news is that the cost has been lower and there are more and more places for the cars to get electricity ever since 2010.
The other choices are other liquid fuels. Many of these can be stored in the same places as gasoline, and used in the same cars. They can also be friendly to the environment.
One way to make such fuels is to get CO2 from the air and put it in water. Through chemical reaction, hydrocarbons can be created. However, these fuels take up more space.
Another way is to make such fuels from plants which take in carbon from the air. These fuels are greener in use. But not all of them can be as efficient as gasoline.
For a fuel to be the best, people have to be able to afford it. Unluckily, almost every green technology is more expensive than that of using gasoline. Governments and car producers are doing everything they can to cut down the costs. In the end, the best fuel will be both affordable for car users and green for our planet.

When do children start to talk? If you ask a group of parents when this happened, most will say “around twelve months of age”. They will probably even remember what the children said. Many parents keep a diary of their child’s “first words”.
We can never predict what a first word is going to be. Often it’s the name for “mummy” or “daddy”, but it could just be the word for an animal or a favorite toy. Everything depends on what has most caught the child’s attention. But one thing is certain: after the first word, others come quickly. By 18 months, most children have learned about 50 words. By two, the total has risen to around 200.
Early words are actually one-word sentences. One of the first features(特征) of language a child learns well is to control the rise and fall of the voice to make the difference between stating and questioning. In English, daddy with a high rising tone(声调)means “Is that daddy?” Daddy with a high falling tone means “There’s daddy”. Of course, only very basic meanings can be communicated using tones alone. So it soon becomes necessary to learn some grammar.
In English, grammar means learning to put words in different orders. Children have to see that mummy push is different from push mummy. They start practising such changes at around 18 months. By two, they have learned the basic patterns of word order, and we hear them saying such things as man kick ball and where daddy go.
What are the parents doing all his time? They’re acting as teachers and they always have an active role to play in their child’s language learning.
1. What might an English child say first when learning to talk?A.Mummy. | B.Push mummy. | C.Man kick ball. | D.Where daddy go? |
A.About 6 months old. | B.About one year old. |
C.About 18 months old. | D.About two years old. |
A.Word order. | B.Word tones. | C.The first words. | D.Correcting words. |
A.Use grammar well. | B.Tell stories. | C.Write passages. | D.Make speeches. |
A.Teachers. | B.Parents. | C.Friends. | D.Grandparents. |
【推荐3】①Corals (珊瑚) can produce CaCO3 under their bodies. This turns into hard, rock-like reefs which become homes to 25 percent of all sea life. What if our homes can also naturally grow, just like reefs?
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. |
C.Because producing Biolith gives off carbon dioxide in the air. |
D.Because the growth of Biolith doesn’t give out any heat. |
A. | B. |
C. | D. |
A.New technologies make it possible to live on the moon. |
B.Corals are homes to all sea life. |
C.Researchers use bacteria to “grow” houses. |
