In this outbreak,medical protective masks(GB 19083-2010) and medical surgical masks (YY 0469-2011) are preferred.The above two types of masks are mainly for medical staff and are in short supply now.We can also choose medical care masks.

As for other types of masks,such as cotton masks,sponge masks,activated carbon masks,these are not suggested. Although they look thick,they have no effect on preventing viruses,while medical masks look thin but have good effects.

When removing the mask,you should remove the ear ropes from both ears,do not touch the outside surface of the mask,and throw it directly into a safe trash bin.

If you want to reuse the mask,do not put it directly in the bag,pocket,etc.You can fold it from the inside to the outside and put it in a sealed(密封的) bag.

People use languages to communicate. Any language has its ways to express people’s minds. One of the ways in common is the use of idioms. An idiom is a group of words. It has a special meaning that is different from the usual meaning. For example, under the weather is an idiom meaning ill. So when people say “I’m under the weather," they are saying that they’re not feeling well. Another example, in all weathers means in all kinds of weather. So, “There are homeless people sleeping on the streets in all weathers" tells us that homeless people sleep on the streets no matter whether it is cold or hot.

Different languages may have different ways to make idioms. For people who are learning a foreign language, idioms could cause misunderstandings and bring them endless headaches. On the other hand, if things are done right, idioms can also be a fun way of looking into a new culture and understanding how the people think and talk.

Metaphor (比喻) is often used in idioms. Let’s read the following two examples:

● It makes my blood boil (煮沸) when people litter.

● The night was dark and quiet; my blood ran cold when I heard a strange noise outside at dark night.

In neither situation above, our blood can reach the point so high or so low in temperature. Yet, with the situations the two sentences created, it is not difficult to work out the unhappy feelings of really angry in the first example and very afraid in the second.

Of course, not all idioms are this easy to understand. When we come to idioms of a foreign language, a good dictionary of idioms is always suggested.

1.This passage tells us something about __________ in the English language.

A.grammar B.writing C.reading D.idioms

2.If your brother breaks your computer, you can say to him, “__________.”

A.I’m under the weather B.I’m there in all weathers

C.You’ve made my blood boil D.My blood runs cold

3.What is the writer’s advice when you come to an expression like under the weather?

A.We should look it up in a good idiom dictionary.

B.We should try to express our minds with it.

C.We should find an interesting way to learn it.

D.We should create situations to guess its meaning.
