Due to the outbreak of the novel coronavirus pneumonia, many people are wearing mask to reduce the risk of infections (感染). It’s a very simple but incredibly useful method to protect oneself from a variety of harmful things. In fact, masks have been helping mankind for centuries.

1st century

In that era, many people in Roman Empire work underground in mines to support their families. But most of them suffered from and even died of respiratory (呼吸的) illness. To solve this problem. Pliny the Elder (23-79 AD) a Roman naturalist, recommended the use of animal skins to stop dust from being breathed. His ideas was considered the very first recorded mask inventions.

16th century

Many centuries later, the artist and inventor Leonardo da Vinci (1452-1519) in Italy, suggested using a wet cloth over the face to protect against the poisonous chemicals.

19th century

The design of the mask took a big forward in the 19th century. In 1848, American Lewis Hassley became the first person to patent (注册专利) a protective mask for miners. Masks at this stage were similar to gas mask Later. in 1897. Polish-Austrian doctor Johann von Mikulicz Radecki designed a simple mask with one layer of gauze (纱布), recommending medical workers to wear it to prevent infection. That was the first recorded use of masks for surgeons.

20th century

In 1910, a terrible disease broke out in Northeast China Chinese doctor Wu Liande designed a cheap face mask called “Wu’s mask”. Made of two layers of surgical gauze, it could be fixed around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was simple to make and had a low production cost.

Modern exploration

With several outbreaks of infectious diseases and the flu and the rise of pollution caused by industrial waste, the materials in masks have continued to evolve ( 进 化 ) to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90, which can filter out this fine particulate (微粒) matter, become highly popular. In the future, masks will continue to improve, hopefully so will the habits of humans.

Most of us eat to satisfy our appetite (胃口) for delicious food. But due to the outbreak of the novel coronavirus pneumonia (NCP), many Chinese people are changing their eating habits.

Because of busy work schedules, ordering simple and quick meals online used to be common for many young people in China. Zhang Xiaoyan, a 30-year-old from Nanjing, was one of them.在工作日，她通常在办公室吃外卖食品而不是在家下厨。Even on weekends, she would prefer takeout food, which demanded (需要) little time.

Now, she rolls up her sleeves(袖子) and cooks for herself. “Cooking sometimes is quite time-demanding but it helps me have a healthy eating habit.” Zhang told China Daily.

Instead of eating in the restaurant, cooking at home has become more and more popular. Some even share food videos on their We Chat Moments at meal times.这被认为是一种与朋友沟通的特殊方式。

Besides eating at home, many people also developed the good habit of using serving chopsticks and spoons. They thought it was not clean to use their own to eat dishes. They also eat separately in order not to get infected (感染).

Healthy eating habits and maintaining good order have become real problems for us. It’s related to people’s health and safety, and it’s also a personal responsibility during the pandemic (疫情) stated Guangming Daily.

The disease is still spreading, and more must be done to bring it under control. As long as these habits are good for our health, we should keep them from now on to fight against the virus.

The novel coronavirus pneumonia (NCP) has already made tens of thousands of people sick. Where did the virus come from? Scientists say it probably came from bats.

Bats can carry and transmit more than 60 viruses that can infect humans， Live Science noted. They include the world’ s deadliest viruses，such as Ebola and HIV. Due to their strong immune systems (免疫系统)，bats are able to host these viruses and not get sick. At the same time，the viruses keep developing inside the bats to create new variants (变体). These variants can then infect new hosts，such as other wild animals.

Pangolins (穿山甲)，for example，might be an intermediate host (中间宿主) for NCP，according to a recent study by Chinese scientists. This means that bats might have given the virus to pangolins，with pangolins then spreading it to humans.

Wild animals like snakes，hedgehogs (刺猬) and bamboo rats also carry various viruses. But since they live in the wild，there should be few chances for humans to come into contact with them and get infected—unless the animals are eaten or used to make animal products. When people hunt， buy and eat wild animals， they can introduce viruses to the rest of the population.

But this doesn’t mean that we should kill wild animals. Each species has a role in the eco-system (生态系统) and all of them are important in keeping a natural ecological balance. The lesson we can learn from disease outbreaks is to respect and protect animals and to live in harmony with them instead of hunting，killing，or eating them.

1.Why can bats host many viruses without getting sick?

A.Because these viruses are not deadly.

B.Because the viruses are kept in balance.

C.Because they have strong immune systems.

D.Because they can spread the viruses to other animals.

2.The underlined word“harmony”in the last paragraph probably means　　　　　 .

A.danger B.peace C.pain D.surprise

3.According to the story，what lesson should humans learn?

A.Research more about wild animals. B.Exercise regularly to stay healthy.

C.Stop keeping animals as pets. D.Don’t buy or eat wild animals.

九年级英语单选题中等难度题查看答案及解析

As the novel coronavirus pneumonia（新型冠状病毒肺炎） makes students to stay at home, they have to learn online and smart phones（智能手机） make online learning become possible and easy. But have you ever thought about what they mean to your eyes?

According to a study, half of the British people own smart phones and they spend an average （平均） of two hours a day using them. There has been a 35% increase in the number of people in the UK who suffer from shortsightedness（近视） since smart phones were introduced there in 1997.

Staring at（盯着看） smart phones for a long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink （自动眨眼） a certain number of times. However, when you look at things closer to your face, the blinking slows down. This reduces the amount of tears and causes discomfort（不适） in your eyes. Another bad habit is using smart phones in dark rooms before going to sleep. If you look at a bright screen while your pupils（瞳孔） become larger, too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma（青光眼）.

If you have to use your smart phone to learn online, there are a few things you can do to protect your eyes. Hold your phone at least 30 centimetres away from your eyes when using it. Take a rest every hour and try the following: look at something at least five metres away from you and then focus on（专注于） the tip（ 尖端） of your nose. Repeat this several times. It should reduce the discomfort in your eyes.
