    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.
