Nanotechnology is a new type of science that will be widely used in many fields. Do you want to know more about it?
Imagine: A television screen has the size and thickness of a piece of paper. You carry it around in your pocket and take it out when you want to watch a show. (1) A guitar is so tiny that you can’t see it with human eyes, but you can hear sounds when its strings are pulled.
(2) Nanotechnology is the science, and this kind of science can deal with things in a very small way. It is being studied and developed all over the world. Many scientists say nanotechnology will produce the next industrial revolution（工业革命）.
(3) 也许纳米技术对医学将有最大的影响。 Imagine nanobots in medicine. Thousands or even millions of tiny machines can be sent into the human body with specific tasks. For example, (4) they can be designed to find and destroy cancer cells or viruses（病毒）. Other machines may stay in the human body forever to help organs（器官） that are not working properly.
When could all of these happen? Scientists predict that most of these are possible in the next 30 years. Thousands of scientists around the world are working on these micro-machines. Nanotechnology is just around the corner.

On October 11th in 2020, three new asymptomatic (无症状的) cases of COVID—19 were reported in Qingdao. The government held a meeting: Large-scale- nucleic acid testing (核酸检测) and thorough screening of possible infected (感染的) persons should be carried out.
In order to quickly and orderly complete the detection (探测) of all the citizens, more than 20,000 volunteers have been arranged to five urban areas to participate in the test. The volunteers are mainly public security officers, government workers, community workers and the public. Because of the large amount of nucleic acid testing of all persons, the “10 in 1 mixed sampling detection technology” (混合采样检测技术) was accepted in the detection work, which can be used in large-scale screening, and its biggest advantage is to improve efficiency.
1,038,785 nucleic acid samples were collected in Qingdao, and 312,977 samples were detected. As of 18:00 on October 16th, Qingdao had completed nucleic acid testing of all the people of 10,899,145, and the results were all safe.
On October 14th, a reporter was surprised to introduce the situation in Qingdao, saying that Qingdao completed more than million samples of nucleic acid testing within three days, but this has not affected the normal life of local people. The supremacy (至上) of people and life is not an empty slogan (口号), but a strong and solid action, which is soaked (渗透) in vivid details and has fulfilled the promise to the people.

As Earth’s neighbor, Mars (火星) has a similar environment to Earth. For years, scientists try their best to study Mars and hope that people can live on it one day. So China has named the nation’s first Mars rover (探测器) Zhu Rong and sent it on Mars successfully. It is the sixth rover on Mars. For all of us, Zhu Rong is a well-suited (非常合适的) name.
In an ancient Chinese story, Zhu Rong had the face of a man and the body of an animal. He rode on two dragons. When he had a big fight with Gong Gong, the god of water, Zhu Rong won. But after the fight, the human world came into complete darkness. Then he brought fire from heaven to the world.
“Zhu Rong is regarded as the earliest god of fire in traditional Chinese culture.” A space official said, “The first Mars rover was named Zhu Rong. The name stands for light and hope for space exploration in our country, and means to guide humans to continue exploration.”
After leaving the earth, Zhu Rong circled Mars for several months and landed on it on May 15th, 2021. Zhu Rong had traveled 1921 meters by March 2023. In recent years, our country has sent up the world’s first quantum satellite (量子卫星), and we have our own space station. We have made great progress in space technology.

Google glasses are like a clever friend. You can talk to them through voice activation (语音激活) if you get lost. You can say “Glasses, where am I?” Then the built-in GPS system will find you and tell you where you need to go.

But they save you the trouble of having to pull it out of your pocket.
Google glasses are like a secretary. You can tell them what you want to write in an email and they will type it for you.
Three years ago, there were only a few volunteers wearing Google glasses. Google was testing on them before they were officially released (发布) at the end of 2013. A lot of the volunteers complained the glasses made them look silly. You could buy Google glasses in the market for about $1, 500 by the end of 2015. In July 2017 it was announced that the second iteration, the Google Glass Enterprise Edition, was in the US for companies such as Boeing.

【推荐1】Wang Yue, a grade-seven student from Jiangsu, opened a study app to see how to solve a difficult math problem. However, a lot of game advertisements popped up(突然出现), which made her very angry.
In fact, that is just one of several disappointing things about study apps that are widely used by students. Study apps aim to help students learn. For example, students can check answers to problems and take online courses(课程). However, with more study apps coming into the market, serious competition has caused some apps to change. Making good use of them has become a problem.
Some study apps have social media features(社交媒体功能) that can disturb students. Li Xieyi, 14, from Sichuan, has noticed this. “I once joined a chat group to learn from others. However, hundreds of messages appeared on my phone,” she said. So, she left the chat group. “If you don’t have self-control, just pay attention to studying, don’t use study apps,” she said.
In addition, some students simply copy answers from study apps. Zhang Shiyuan, 14, from Shanghai, often sees her classmates do so. But she has a better way to use study apps. “They show many ways to solve one problem. I try them one by one and see how they work. Then I use the things I’ve learned to solve the problem again,” she said.

【推荐3】Shopping is a very important part of life, but shoppers are faced with a confusing and rapidly changing situation. The prices of clothes, shoes, and make-ups have gone sky high, so it is important that you do not waste your money and that you shop carefully for value. There are traditional ways of shopping: shopping in a department store, in a boutique（精品店）, in a market. People shop around for the best price and quality. “To shop till you drop” is an American idiom（习语）which means to buy things from shop to shop until you are tired and can’t walk any more. However, with the continuous development of society, the way of shopping for Americans has changed a lot today.
Catalog（目录）Shopping
People in the United States often shop from catalogs. There are special catalogs for almost every need, which include clothing, furniture, health and beauty products, footwear and so on and so forth. People also order about 40% of their music from music club catalogs. Customers say that music stores are too noisy.
Television Shopping
Television shopping began in 1986. About 5% to 8% of the American public now shop by television. Some popular shopping channels are the Home Shopping Network and QVC. Customers say that television shopping is easier than shopping in a store. How do they buy things? They make a phone call and use their credit card to buy things. And TV shopping channels are on late at night, so people can “go shopping” anytime.
Online Shopping
Online Shopping is a form of electronic business which allows customers to directly buy goods or services from a seller over the Internet using a web browser. Now more and more customers go online shopping because of the convenience. As of 2017, customers can shop online with the help of different computers and devices, including desktop computers, laptops, tablet computers and smart phones.
