1 . After just a few days of training, dogs in Germany can be able to identify people who got COVID - 19, according to researchers. The dogs, part of a study by a university in Germany, were able to sniff (嗅出)out the virus exactly.
According to the study published in BMC Infectious Diseases, after receiving training for just five days, eight dogs from Germany's army could identify people with COVID - 19. They sniffed the saliva(唾液) of more than 1,000 people, both healthy and ill identifying the virus with a 94% success. "We think this works because people with the virus have completely changed their chemical smells, and we think that the dogs are able to sense the specific smell changes on those patients,“ Professor Dr. Maren Von said in a video on the study Thursday.
Dr. Holger Volk, another professor from the university, said that dogs have a sense of smell that is 1,000 times better than humans, so they have great potential(潜力) within the medical field. "We know for a very long time that dogs have been used in all walks of life, but for identifying patients, it's a new thing at present," Volk said. "People have not really realized the potential a dog could have to tell patients from healthy people.

2 . Dubai is the commercial capital of the oil-rich United Arab Emirates in the Persian Gulf. But officials want to turn it into the world’s “smartest” city. Earlier this year, Dubai announced plans to be the world’s first city to use self-driving taxis. In June, it placed the first robot police officer at shopping centers and places popular with visitors. Dubai police officials now say they plan to use self-driving vehicles to patrol (巡逻) city streets by the end of the year.
Dubai will be the first in the world to use the O-R3 vehicle, according to the Singapore company that builds it. The company, OTSAW Digital, recently signed an agreement with the Dubai Police force to supply the driverless robots.
The vehicles look a lot like most other automobiles, but are much smaller. They are equipped with cameras, machine learning tools and 3D technology to help them operate independently. The robots automatically charge themselves when power gets low.
The vehicle’s cameras can scan faces and record registration information to check for criminals and possible illegal activities. A police official said the robot can recognize people in any area. It will be used to “identify suspicious objects and follow suspects.” “We seek to increase operations with the help of technology such as robots,” said Dubai’s police chief. “We always search for the best technology to serve our police work for a safer and smarter city.”
The O-R3 can communicate with computers at police centers in different locations. The patrolling robot is able to send data and video to the centers, where operators can control the vehicle remotely. The vehicles can also work together with drones (无人机) that can be launched from the back of the robot. The drones can then follow the vehicles and provide more support from the air.
The CEO of OTSAW Digital, Ting Ming Ling, says the use of such vehicles is designed to help humans with their jobs, not replace them. “Eventually, robots exist to improve the quality of human lives, where men take on high value jobs while robots perform the low skilled ones,” he said.

3 . When most high school students complain about having to wake up extra early，they're usually referring to a swim practice before class or the last minute study before a test. But that was never the case for Corey Patrick，who woke up at 4：30 every morning last year in order to arrive on time at Tarrant High School in Alabama.
Patrick had attended Tarrant City Schools since his fourth grade，but things got difficult when his family moved to a town 14 miles away. Even though his family didn't have any forms of transportation，Patrick didn't want to miss out on his senior year with friends，so he woke up at 4：30 every morning in order to make it to a 5：41 a．m.bus that would help him get to Tarrant on time.And just as he had done every other school day of the year，Patrick got up one morning to start the journey from his home to his high school; the only obvious difference that morning was that he was wearing his graduation gown (毕业礼服)，which made that day's bus driver，DeJuanna Beasley, take some photos of him. She then shared them online with these words，“You tell me this isn't determination.He got on my bus to go to his graduation，and no one was with him.Sometimes it's all in what you want out of life.I was so proud of this young man.”
That was soon shared by many people online，and it caught the attention of radio host Rickey Smiley，who surprised Patrick by giving him a car later. Smiley confirmed that he would make sure that Patrick received help with getting his driver's license. A GoFundMe was also created for Patrick，which has raised over $20,000. And Patrick has got a scholarship (奖学金) to Jacksonville University，where he plans to study computer science.

4 . My name is Lwazi Nzimande. I started my schooling at Thukeyana Primary Farm School in Underberg, KwaZuluNatal.
I had a favourite teacher in primary school. Her name was Miss Dube. She taught me natural science and human social sciences in grade six and seven, and had a way of pushing learners to be able to think for themselves. She made sure that each and every learner took part in every lesson. She used pictures, diagrams (图表) and other things to make learning easier and more unforgettable, moving at a pace that was suitable for all students. As a teacher, she showed patience, respect, open-mindedness, and reliability (可靠性). Now you see why she was my favourite teacher in primary school, don't you?
In my opinion, patience, respect, open-mindedness, and reliability are some of the things that all teachers should have and show. A patient teacher is one who understands that some learners need more explanation than others to understand something in class. He or she should always be willing to help learners. An open-minded teacher will go beyond what is found in the textbook. A teacher who is respected will find it easy to control a class. Respect is earned through what a teacher says to learners or how he or she deals with them in general.
Miss Dube often told us not to badmouth or make fun of others. She also did so. She never badmouthed other teachers in front of us. Also, Miss Dube never made fun of her learners. She thought making fun of learners in front of others would hurt them and damage their confidence.
Miss Dube was also very honest. From my point of view, that's also what a good teacher should be like. If she didn't have an answer to a question, she would let her learners know. This set a good example to the learners.
1. Why was Miss Dube the author's favourite teacher?| A．Because of her rich knowledge. |
| B．Because of her good appearance. |
| C．Because of her teaching style and character. |
| D．Because of her lifestyle and attitude to students. |
| A．Pay close attention to every student's improvement. |
| B．Tell about something outside the textbook. |
| C．Avoid believing everything in the textbook. |
| D．Show great respect for her students. |
| A．She liked praising her students. | B．She was very confident in class. |
| C．She got along well with other teachers. | D．She set a good example to her students. |
| A．Being a very patient teacher. | B．Answering students' questions. |
| C．Being honest in front of students. | D．Teaching students very difficult things. |

6 . Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships don’t last very long. To have a friend, you must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous(宽宏大量的); be understanding.
Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven’t been honest, you may lose your friend’s trust. Good friends always rely on one another to speak and act honestly.
Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.
Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend’s place so that you can understand the problem better.
No two friendships are exactly alike(相同的)．But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.
