Health officials in the United States reported last week on what they believe could be a medical first. Officials said doctors performed what could be the first double lung transplant（移植）on a person whose lungs were severely damaged from vaping（吸电子烟）. The operation reportedly saved the life of the teenager.

The young man was admitted in early September to a Detroit-area hospital with what appeared to be a common lung infection, but was later sent to Children’s Hospital of Michigan in Detroit. On October 3, he was transported to Henry Ford Hospital, where the transplant was performed 12 days later.

Hassan Nemeh is a surgical director of thoracic（胸腔的）organ transplant at Henry Ford Hospital. He told The Associated Press（The AP）that the damage done to the teenager’s lungs from vaping was so bad that there was no possibility to totally recover. He warned parents to think about that and to tell their children as well.

More than 2,000 Americans who vape have gotten sick since March. Many of them are teenagers and young adults. At least 40 people have died.

Recently, the U.S. Centers for Disease Control and Prevention reported a discovery into what might be causing people who vape to become sick. They identified the chemical compound vitamin E acetate（醋酸盐）as a “very strong criminal”.

Researchers found the chemical compound in fluid taken from the lungs of 29 patients. In other studies, Vitamin E acetate was found in liquid from electronic cigarettes and other vaping devices. Many who got sick said they had vaped liquids that contain THC, the part of marijuana that creates what is known as a “high”.

Dr. Lisa Allenspach is a lung specialist and medical director of Henry Ford’s Lung Transplant Program. She told The AP, “Vaping-related injuries are all too common these days. Our adolescents are faced with a crisis.” She added that vaping products should not be used in any way.

Dr. Nemeh said the 17-year-old patient’s case does not open any new moral considerations about transplants for people who severely damage their own lungs by vaping. He added, “We hope sharing this patient’s story prevents anyone else from experiencing a vaping injury that would require a transplant.”

    Japanese scientists and technology companies are coming up with new ways to deal with employee shortages in delivery service. How exactly? By introducing a robot that can deliver food to your home. A Japanese company ZMP has launched robot tests recently.

The ZMP's delivery robot in the process of testing is a red box that measures 109 cm and 133 cm in heights and lengths respectively. It is designed to carry up to 100 kilograms of anything with a approximate speed of 4 miles an hour. It has its own navigating system and a map, sensors(传感器)and cameras that allow it to self-drive. These, for now, are its main technical abilities. The next developments will be control of food temperature, and perhaps，voice control and speaking abilities.

The robot will be tested together with a local sushi(寿司)delivery company Ride on Express Co. Upon making a sushi order, customers will receive codes on their smart phones that will allow them to unlock the robot and get their orders out. Similar testing attempts have been undertaken by Domino's Pizza in Australia, where they tested a delivery robot a year ago.

In any case, before robots are able to deliver food or any other goods to real customers, massive testing on public roads or in the public air space will have to take place. While it is in the government's best interest to make up for the shortage of delivery in the Japanese labor market, it is clear that self-driving machines of any kind will not be permitted on the roads until they are fully tested and proven safe enough for public roads. According to the experts, this could take another 3 to 5 years.

In any case, robot delivery is not such a distant future after all, and recent developments show that there is significant market demand for such type of delivery.

C.Employee Shortage in Delivery in Japan D.Latest Automatic Service：Robots

    Stephen Hawking was regarded as one of the most brilliant physicists in history. His work on the origins and structure of the universe, from the Big Bang to black holes, changed the field greatly. His best-selling books also appealed to a number of readers.

Stephen Hawking had a challenging life. He was born in England on Jan. 8, 1942-300 years to the day after the death of the astronomer Galileo Galilei. He attended University College, Oxford, where he studied physics, despite his father’s urging to focus on medicine. Hawking went on to Cambridge to research cosmology.

In early 1963, just before his 2lst birthday, Hawking suffered from a serious disease, more commonly known as Lou Gehrig’s disease. He was not expected to live more than two years. Completing his doctor’s degree did not appear likely. Yet, Hawking had overcome the great difficulties, not only attaining his Ph. D. but also building new roads into the understanding of the universe in the decades since.

Hawking continued at Cambridge after his graduation, serving as a research fellow and later as a professional fellow. In 1974，he was inducted（正式就职）into the Royal Society，a worldwide fellowship of scientists. In 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world.

As the disease spread, Hawking became less mobile and began using a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy（气管切开术）caused his total loss of speech. A speech-generating device was constructed at Cambridge, combined with a software program, serving as his electronic voice and allowing Hawking to select his words by moving the muscles in his cheek. Hawking died on March 14, 2018.

    China is recognized as a world leader in the development of artificial intelligence and facial recognition systems. A Chinese company says it has created a new facial recognition system that can identify people even if they are wearing masks. Engineers at the Beijing-based company say their system is the first to be created to effectively identify people wearing face masks.

The company told a news agency that a team of 20 people built the system in about a month. The system is based on existing technologies developed over the past 10 years. The process involved adding a collection of about 6 million unmasked faces and a much smaller collection of masked faces, the company said.

The company is now selling two main kinds of products that use the new technology. One performs "single channel" recognition, which is designed to be used at the entrances to buildings.

The other product is a "multi-channel" recognition system that uses groups of surveillance cameras. It can identify individuals in a crowd of up to 30 people "within a second.

"When people are wearing a mask that covers the mouth and the nose, the recognition rate can reach about 95%, which can ensure that most people can be identified," said Huang, vice president of the company. He added that the system's success rate for people not wearing a mask is about 99.5%.

However, the new system struggles to identify people wearing both a mask and sunglasses. "In this situation, all of the key facial information is lost. In such cases recognition is tough," Huang said.

People were reacting differently to the new technology. While some citizens have been against using such tools, the majority have accepted the technology as an effective way to decrease crime and catch criminals.

1.What did the company do to build the system?

A.They gathered many face images.

B.They employed hundreds of people.

C.They used the latest technology.

D.They spent about a decade building it.

2.According to the passage, which of the following can be true?

A.The new system has already been used by the police.

B.The recognition rate of masked faces is about 99.5%.

C.It's hard to recognize people with masks and sunglasses.

D.The single channel product is as powerful as the multi-channel.

3.Which of the key facial information might have the biggest impact on recognition rate?

A.One's eyes. B.One's nose.

C.One's mouth. D.One's hair.

4.What is the main purpose of the text?

A.To show conflicting attitudes toward the system.

B.To introduce a new facial recognition system.

C.To advertise two products of facial recognition.

D.To show the advantages of facial recognition.
