Masks, a simple protective tool, have been used by people for a long time. They can not only prevent epidemics, but also protect us from other harmful things, such as smog (雾霾) and chemicals. When was the protective mask first invented and how did it develop? Let's take a look.

1st century

At this time, lots of people in the Roman Empire worked underground in mines (矿井). Many died of lung (肺部) diseases caused by dust. Pliny the Elder (23-79), a Roman philosopher, used animal bladders (膀胱) to protect miners from the dust. This was the first recorded use of protective masks.

16thcentury

Italian artist and inventor Leonardo da Vinci (1452-1519) advised people to wear a woven (纺织的) cloth dipped in water over their faces to protect against harmful chemicals.

19th century

In 1848, American Lewis Hassley became the first person to patent (注册专利) a protective mask for miners. In 1897, Polish-Austrian doctor Johann von Mikulicz Radecki designed a simple mask with one layer of gauze (纱布). He advised medical workers to wear it to prevent infection. This was the first use of a surgical (外科的) mask.

20th Century

In 1910, the pneumonic plague (肺鼠疫) broke out in Northeast China. Chinese doctor Wu Liande designed a face mask called 'Wu's mask'. It was made of two layers of gauze. The mask was praised by experts around the world because it could be produced easily and cheaply.

Today

With several outbreaks of flu and the air pollution in recent years, masks have continued to develop. For example, in 2012, when China suffered from smog, mask models such as N95 and KN95 became popular. They can filter out (过滤掉) fine particulate matter (微粒物). China is now the world's largest mask producer, making out half of the world's masks.

An idiom is a phrase that we can’t understand from the meaning of each word. For example, if an American boy asks his mom what’s for dinner tomorrow, she may say “I’ll play it by ear”, that means she doesn't have plans for dinner and she will decide later.

“Play it by ear” used to mean playing music without using the sheet music(乐谱), but now people often use it when they’re not talking about music!

There are many idioms in English. If you learn to use them, your English will be much more vivid(生动的)and colourful.

Have you ever heard the idiom “He bought the farm”? It means he died. Do you know how it became popular? It was first used during World War I. When a soldier died, the government gave his family enough money to buy a farm.

In the early 1930s, people in the U.S. often did not know when or where their next meal was coming from. So as soon as they got something in their hand that could be eaten, it would go into their mouth. That was how people began to use the idiom “living hand to mouth” to mean “living a poor life”.

And don’t be angry if your English friend says this to you, “Break a leg in your game!" In fact, he is wishing you good luck! Hundreds of years ago, people believed in sprites. Sprites enjoyed causing trouble. If the sprites heard you ask for something, they would make the opposite take place. Tell someone to “break a leg” and the sprites would make something good take place.

Aren’t English idioms interesting? And break a leg in your next football match!

3.We can infer(推断)that in the early 1930s common American people________

A.loved buying farms. B.lived a hard life.

C.had meals at different places and times. D.liked eating from their hands.
