Which type of mask should we choose?

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.

本文主要解释了口罩的一些问题：如我们要选择哪种口罩，多久换一次口罩，怎么脱口罩，口罩用完之后放哪里等。

1.

词义猜测题。根据第1大段“and demonstrated how to wear and remove a mask properly in person.”亲自示范了怎么戴和脱下口罩。可知，remove是脱下的意思。take off脱下；turn off关掉；put on穿上；take out取出。故选A。

2.

3.

细节理解题。根据第5大段“The mask nose clip(夹子) doesn't work.·The mask ear ropes don't work·Breathing resistance(阻力) increases.”口罩夹子没用了，口罩的耳朵线变松了，感觉呼吸困难了。可知，ABC都是。故选D。

4.

细节理解题。根据第9大段“For ordinary people，throw the mask directly into the trash bin”可知，对正常人来说，直接把口罩扔进垃圾桶，故选A。
