There's been increased attention on this in recent weeks, with the unsettling spread of the coronavirus around the world. When a video of Naomi Campbell cleaning her airplane seat and wearing a mask and gloves was shared online last year, it made the rounds because her behavior seemed exaggerated. “ 1. And we know that germs can live on surfaces for a long time, so it doesn't hurt to clean it," said Aaron Milstone, an epidemiologist at the Johns Hopkins Hospital. Here are some tips for cleaning your area of a plane and keeping healthy on a flight.
Keep your hands clean and stop touching your face
"Wiping down surfaces on a plane won't hurt, as long as it doesn't give you a false sense of security,” Andrew Mehle, associate professor of medical microbiology said, stressing that cleaning your space on a plane should be done in conjunction with washing hands and following other best practices. Good habits are not easily formed. 2. Doing so after touching a surface where droplets from when someone sneezed or coughed can lead to the virus being passed on.
3.
A study from Emory University found that during flu season, the safest place to sit on a plane is by a window. Researchers studied passengers and crew members on 10 three-to-five-hour flights and observed that people sitting in window seats had less contact with potentially sick people.
Disinfect hard surfaces
When you get to your seat and your hands are clean, use disinfecting wipes to clean the hard surfaces at your seat like the head and arm rest, the seatbelt buckle（带扣）, the remote, screen, seat back pocket and the tray table. If the seat is hard and nonporous （无孔的）or leather, you can wipe that down too. 4.In addition, pay attention to your disinfecting wipes, which would typically say on the packaging how long asurface needs to stay wet in order for them to work.5. In order for the wipes to work, you need to follow those time requirements.
A.Choose a window seat.
B.A window seat is the best option.
C.The airplane and airplane seat is a public space.
D.Good habits arc essential in this particular time.
E.That time can range from 30 seconds to a few minutes.
F.Most people tend to touch their faces more often than they realize.
G.However, using wipes on cushions could lead to a wet scat and spreading of germs.
Pollution's serious effects on the environment have become more obvious in recent years. Most scientists agree that efforts are necessary to protect our environment from further harm. As we know, the construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. So green buildings are in great need.
The environmental benefits of building green include the protection of ecosystems and biodiversity（生物多样性）, improved air and water quality, less waste flowing into streams and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there.
The process of building green includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances.
Careful site selection is important to minimize（最小化）human effect on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes（微风）and sunlight can reduce energy use and expenses. More energy and expense are needed for larger buildings as well, so it is important to build small.
Green roofs are another feature of green houses that reduce energy use and cost. These roofs are partially or completely covered with plants, which helps to keep heating and cooling costs low, prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water protection, recycling and waste reduction. In addition, renewable energy sources such as solar power, water power and wind power are used for heat and electricity, which greatly reduces costs and decreases the influence on the environment.
1.Which advantage is not included about the building green?
A.To upgrade the quality of air and water.
B.To reduce the waste flowing into streams.
C.To protect the ecosystems and biodiversity.
D.To enhance our human being's life quality.
2.What is a green building probably like according to paragraph 4?
A.Small B.Large.
C.Warm. D.Cool.
3.Why do we choose to use green roofs?
A.To fit the environment, B.To lower expenses
C.To collect nature water. D.To keep warm or cool.
4.What is the text mainly about?
A.Environmental benefits. B.Building green.
C.Promoting energy efficiency. D.Ecosystems and biodiversity.
A table-waiting robot cat built by a Chinese technology firm can carry plates of food, navigate a restaurant, miaow（喵喵叫）at diners—and even react to having its ears stroked.
Making its debut at the 2020 Consumer Electronics Show in Las Vegas, the so-called BellaBot was built for Chinese restaurants lacking enough waiters. It is the brainchild （智慧结晶）of the Chinese robotics and artificial intelligence firm PuduTech.
It features four shelves in the center of its tower-like body to carry plates. Having been loaded up with meals by its human colleagues, the cat-themed robotic waiter miaows when it delivers food to diners to encourage them to take their plates. If customers thank BellaBot by stroking its ears, it will initially respond with a look of pleasure on its on-board screen, which displays animations of a cat's face. “The owner's hand is so warm,” BellaBot has been programmed to respond.
However—much like a real cat—the robot’s reaction soon changes if it is petted for too long. “It gets mad to remind you not to interrupt its job,” the designers introduced.
The BellaBot waiter robot is a more personality-rich update to PuduTech's previous model, which featured a more utilitarian （实用主义的）design and user interface. Both BellaBot and its predecessor were designed with a particular mind to Chinese restaurateurs which are often short of waiting staff.
In a real-world food-service setting, however, BellaBot may find it difficult to operate at peak times. Nevertheless, restaurants are expected to increase their trust on automation—whether in the form of robotic waiting staff or otherwise.
Furthermore, the technology improvements of robotic waiters designs will be grown steadily, especially better at communicating with humans and tackling new activities.
1.Why did the technology firm create the BellaBot?
A.Because the restaurant can react to it.
B.Because it is the brainchild of the Chinese robotics and Al firm.
C.Because the Chinese scientists want to show their talent to the world.
D.Because it is can be used when Chinese restaurants are short of enough waiters.
2.When do the robotic waiters deliver the food to dinners?
A.The customers touch the robotic waiters’ ears.
B.The customers are encouraged to take their plates.
C.The human colleagues have loaded up the meals on robotic waiters.
D.The robotic waiters display animations of a cat's face on their on- board screen.
3.What can we infer from the robot's reaction changes?
A.It wants to remind you to get mad.
B.It wants to remind you to pet it again.
C.It wants to remind you not to help its work.
D.It wants to remind you not to stop its work.
4.What is the author's attitude to the robotic waiters?
A.Doubtful. B.Positive.
C.Negative. D.Ambiguous.
LOS ANGELES — Kobe Bryant was killed in a helicopter crash yesterday in Calabasas. California, along with his 13-year-old daughter Gianna and seven other people. The helicopter carrying Bryant and the others crashed into a hilly area in foggy conditions, and the cause of the crash is under investigation.
Family members, friends and fans are mourning the death of the basketball great Kobe Bryant. Looking back to his whole life, Bryant was widely considered one of the greatest basketball players of his generation. Even after his retirement, Kobe Bryant is still a winner. The former Los Angeles Lakers star won an Oscar in the animated short category for "Dear Basketball,” a poem he wrote after ending his 20-year career on the court in 2016.
He’ll add it to an already jammed trophy collection that includes five NBA championships with the Lakers, two Olympic gold medals, NBA Finals most valuable player awards, a league MVP award and four All-Star game MVP awards.
Since hanging up his basketball shoes, Bryant has thrown himself into business (a new Nike shoe) and various forms of storytelling.
“As basketball players, we're told to shut up and dribble（运球）,” Bryant once said on stage. “I’m glad we did a little bit more than that.”
He thanked his wife, Vanessa, and his three daughters, naming each of them. He spoke a few words of Italian — a language he learned as a child growing up in Italy — and closed by telling them, “You arc my inspiration.''
He was just getting started. And now he's gone.
The tributes（悼念）will continue, though eventually fade away. The legacy will be forever.

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。
“Mommy ,don't go,”my three-year-old son screamed as I walked to the door. My fifteen-year-old leaned against the kitchen counter with his arms folded across his chest ,not screaming,but glaring at me as I pulled his little brother off my leg.
“Are you mad at me too?”
“You spend all your time taking care of other people's kids,but what about us?”Dylan left angrily.
I was shocked and a little hurt. How could my own child not understand that the work I was doing was saving live? Then the answer hit me. He didn't know bemuse he had never seen what Healing the Children actually did. Dylan had heard the sores of sick children, but had never once looked into the eyes of a child and understood the hard truth-that without our help, the child would likely die.
“Get dressed. You are going with me.”I said.
I spend the drive explaining the case of Hector to my son, who pretended to ignore me the entire time.“He's seven, only weighs thirty pounds and is very sick. He has a heart condition called Tetralogy of Fallot, which could kill him. It is a miracle(奇迹) that he is still alive. ”
I went on to explain that it took a team of volunteer medical staff to get Hector to the hospital from his remote village and care for him while he was there. Still, Dylan seemed unimpressed.
We stopped at a convenience store for water and snacks. Dylan had one large and one small Slurpee (思乐冰饮料). He said the small one was for Hector. I doubted whether the little guy would be able to drink it, but remained silent. This was the first interest Dylan had shown in being there. I wasn't about to ruin it.
I stopped at the nurse's station to check on Hector's progress while Dylan went to his room. Our patient was recovering physically，but the nurse was concerned that Hector was struggling emotionally. She said “Kids usually bounce back fast, but he hardly speaks and never smiles.”
