【推荐3】A live-streaming app(直播应用)that monitors(监控)students in classrooms in some middle schools has raised a lot of online discussion. It was reported that any user of the app Shuidi could see inside classrooms. Some parents have praised the app for giving them the chance to monitor their children, while others worry about privacy problems. Do you think the app is a good idea?
Barbara, 16:
I strongly support this app. Nowadays, children play an important role in the whole family, and parents always want to care for their children, wherever they are. This new platform(平台)helps parents see what their children are doing in classes. It’s also a good way to make students behave themselves in school.
Tina, 15:
I’m in favor of this app if parents get their children’s permission first. The app could help parents focus on children’s bad habits. It could also be used as a tool to prevent bullying(霸凌). However, parents should get their permission first to protect their privacy.
Lucas, 16:
I think this app is a bad idea. Schools should be pleasant and relaxing places for students to study and play. But we will feel uncomfortable if cameras are watching us all the time. We should pay attention to our privacy. Our lives shouldn’t be watched by the public.
Frank, 15:
Any form of privacy invasion(侵犯)shouldn’t be allowed. Although some parents want to know more about their children, they should do it in a better way: Being under the eye of strangers is too dangerous.

【推荐1】If you are in Dubai you may notice a robot police officer sharing the street with you. Your first thought might be, "Have I walked into a movie set?"The answer is no. That robot is Dubai's newest police officer. The robot has a touch screen instead of a weapon. The robot will be employed mostly at shopping centers and other places popular with visitors. The robot's face has eyes but no mouth or nose. It stands 165 centimeters tall and weighs 100 kilograms. If the robot works well, Dubai says 25 percent of its police force could be robotic by 2030.
The robot cop was officially presented at Dubai's Gulf Information and Security Expo and Conference in May. Mohammed Elnakib, a telecommunications manager, was surprised when he was met with a "Hi, Mohammed!" from the robot cop. Elnakib said, it was creepy but it is also the future. Then I realized it had read my name tag. This will be a fantastic addition because everything is moving towards doing more with fewer people.
The rolling robot reported for duty on the streets of Dubai. The police hope the robots will make life easier for the people of Dubai. Khalid Al Razooqi is Director General of Smart Services at the Dubai Police. He said the robot can help the public all day, every day, and that "it won't ask for any sick leave or maternity leave."The robot cannot make arrests. But it can recognize faces and compare them to photographs on a criminal database. It can also sense emotions. People can use the robot's touch screen to do things like report a crime, pay fines and report lost or found things. They can also ask how to get somewhere. The robot can salute and shake hands with people. So far, the robot can speak in Arabic and English. It soon will learn other languages such as Russian, Chinese, French and Spanish. Dubai has plans to add other kinds of robots to its police force. Within two years, the city plans to deploy a three-meter-tall robot that can run up to 80 kilometers an hour. The Dubai government says the machine would be the world's largest robot. A human police officer will be able to sit inside and control the robot. It will be able to lift heavy objects. The city also plans to use an egg-shaped robot to supervise parking areas and ticket traffic law violators.

【推荐2】Have you ever seen a solar panel(太阳能电池板)in your neighborhood? Solar panels take energy from the sun and turn it into electricity. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power(给……供电)their homes.
However, solar panels also have their problems. They stop working at night and on rainy days. Is it possible to make them produce electricity all of the time?
Scientists at Suzhou University, China, have invented a new solar panel now. It can produce electricity not only from solar energy but also from falling rain. When a raindrop falls on the solar panel and then rolls(滚动)down, it creates friction(摩擦力)on the surface of the panel, which can then be turned into electricity.
Sun Baoquan is one of the inventors. “Our new invention can produce electricity in any weather during the day,” he says. “It can even provide electricity at night if there is rain.”
The solar panel, however, does not make much electricity from falling rain. So Sun Baoquan is still working hard to improve it. The scientist also wants to make solar panels more flexible, which are as soft as clothing.
The field of solar energy is developing fast. Scientists around the world have been improving solar panels. Some have been working on ways to join solar panels and wind power together. Some have been trying to use sunlight to produce liquid and gas fuels(液体和气体燃料).
1. Which energy is now the cheapest form of electricity in many parts of the world?A.Solar energy. | B.Water energy. | C.Wind energy. | D.Nuclear energy. |
A.It has a larger size than a common one. |

STOCKHOLM, Oct. 7—The 2020 Nobel Prize in Chemistry went to two scientists for their discovery on genome editing(基因组编辑), the Royal Swedish Academy of Sciences(瑞典皇家科学院)announced on Wednesday.
The prize went to Emmanuelle Charpentier in the Max Planck Unit for the Science of Pathogens in Germany and Jennifer A. Doudna from the University of Califomia, Berkeley “for the development of a way for genome editing,” according to the news from the academy.
The two scientists have discovered one of gene technology’s greatest tools: the CRISPR/Cas9 genetic scissors(剪刀). Using these, researchers can change the DNA of animals, plants and microorganisms(微生物)clearly, and moreover, it is now possible to change the code(编码)of life over the course of a few weeks, said the release.
“There is huge power in this genetic tool, which affects us all. It has not only improved basic science, but also resulted in innovative(创新的)crops and will lead to better new medical treatments,” said Claes Gustafsson, chair of the Nobel Committee for Chemistry.
Since Charpenticr and Doudna discovered the CRISPR/Cas9 genetic scissors in 2012, the tool has contributed(贡献)to many important discoveries in basic research, and plant researchers have been able to develop good crops.

【推荐1】Close your eyes and picture a scientist. Does an image of a man show up in your mind?
It is hard to ignore that even in the 21st century the “scientist equals male” stereotype(成见) is still there. In the science world women’s voices are often unheard.
According to UNESCO, only 35 percent of global STEM (science technology engineering and mathematics) students in higher education are women. In pursuing science and technology careers women are more likely to be treated unfairly because of their motherhood and skin color. “Role models of women scientists need to be better represented on important international stages and allow their voices to be heard as a way to encourage youths”, Lenore Blum, a female scientist from the US said.
In December, Talk With Lu Jian, a Chinese TV show, launched a series of programs, including geneticist(遗传学家) Fu Qiaomei at the Chinese Academy of Sciences and Rong Yi, a chief designer of the Long March 2F rocket.
“These female scientists share a strong passion(热情) for science,” said Lu Jian, the TV show’s host. “They are making a pathway(通道) for the next women scientists.” Actions should also be taken to create a better environment for women working in the field of science and technology, noted Science and Technology Daily. For example, they should be given more resources(资源), join in decision-making and gain support for their research during maternity(生育).

【推荐2】①I have just been to the opening ceremony for a new exhibition of early French photographs. Some of them are really beautiful. A French photographer made some very interesting comments about them. Then I went to look at some of my favorite exhibits: a photograph by Lewis Carroll, who wrote the Alice series and also loved cameras and photography, and the Baker’s Boy, a very interesting picture from the 1860s.
②There is so much to see. And the museum has three historic firsts: the world’s first negative(底片), the first moving picture and the first shots taken for television.
③Before I show you around, let me just tell you something about the museum. The National Museum of Photography, Film and Television was first set up in 1983. We have three million different items in different categories(类别). We store a lot of our collection in special rooms to keep it safe, but there is still a lot to see. We are the most visited museum in the UK outside London. We attract over a million visitors a year, and most of them report that they really enjoyed their visits.
④Take the train. It’s very easy. Just go through the city centre square outside the museum and it’s a three-minute walk to Forster Square Station. By the way, before you leave, take a look at the gift shop. It’s rather special. It’s rather great. The kids are loving it.
⑤There will soon be a new attraction here. We will open Experience TV. It will be really interactive. Visitors will be able to use the equipment and go in front of the camera to read the news or present the weather. It will be great fun and very educational.
⑥We have many treasures. There is the Talbot Collection. He was one of the inventors of photography and we have his pictures, letters and notebooks. And we have all the photos taken for a newspaper which was popular from 1912 until the 1960s. Researchers keep on finding new things in it.

Of all the animals on Earth, none are more willing to explore than humans. Other animals will go in search of food or water. But humans can be encouraged by the possibility of discovery. So what is it that caused us to spread out across the world?
Perhaps it’s in our DNA. In 1999, Dr. Chuansheng Chen carried out a study of a gene (基因) known as DRD4-7R. This gene is found in about 20% of all humans. This kind of people are mostly interested in taking risk, exploring. and getting new ideas. Dr. Chen found that DRD4-7R is more common in people who move around a lot than those who don’t. For example, studies in Africa show that the gene is much more common in nomadic tribes (游牧的部落) than in tribes that prefer to stay in one place. Several other researchers have studied this topic and found out more to support Dr. Chen’s research.
But can a single gene be a drive (驱动) for the need to explore? Dr. Kidd doesn’t think so. He thinks DRD4-7R might make people get more curious, but other important sets of genes also give us great minds and skilled hands. He believes that not just one gene, but groups of genes work together to create behaviors like exploration.
The environment we live in also plays a role in our need to explore. For example, during the European Age of Exploration, explorers became rich and famous for their discoveries. This drove others to try to increase their wealth through exploration. Therefore, their exploration was more likely encouraged by money than by genes.
Maybe the need to explore comes from something inside us, such as the DRD4-7R gene. Or maybe it has more to do with what’s happening in the world around us. Maybe it’s both. Whatever the reason, it seems we (or at least some of us) will keep exploring the mountains, the sea, the stars, and beyond, because that’s just what humans do.
1. What did Dr. Chen find about the DRD4-7R gene?A.It has more influence on people in Africa. |
B.It could be found in most of the humans. |
C.It prevents the people in Africa from moving around. |
D.It may be more common in people who like taking risk. |
A.It isn’t the only gene to encourage people to explore. |
B.It can encourage people to have strange behaviors. |
C.It is more important than all of other genes. |
D.It can not be found in animals or humans. |
A.The purpose of exploring. |
B.The importance of the environment. |
