智慧职教: Read the passage. Then listen to the news and fill in the blanks with the information (words, phrases or sentences) you hear.冠状病毒问答（WHO）: What is the correct way to wear and dispose of masks?If you decide to wear medical mask which is pleated and flat like this one, it is important to wear and discard it correctly. Otherwise, instead of protecting you, the mask becomes a source of infection because of the germs that may stay on it.To wear it correctly, you should locate the metal strip at the top of the mask, place over your nose bridge, secure the elastics around your ears, or tie the strings behind your head. Make sure it covers your nose, mouth, and chin. While in use, do not touch the front of your mask.To remove the mask, take the elastics from around your ears or untie the strings behind your head. Do not touch the front of the mask as it may be contaminated. Remove the mask and discard in a closed bin.Cleanse your hands with alcohol hand rub or soap and water. Hand hygiene should be done if you accidentally touch the front of your mask while wearing it. If your mask becomes damp or humid, replace it with a new dry mask. Never reuse single-use masks and discard them immediately into closed bins after each use.For more information on mask use and the New Coronavirus, check WHO website at who.int. u VOCABULARY1. mask n. a covering for part or all of the face, worn to hide or protect it 面具；面罩。例如：a gas / surgical mask防毒面具；医用口罩2. pleated adj. having pleats 打褶的；有褶的。例如：a pleated skirt有褶的裙子3. discard v. to get rid of sth that you no longer want or need 丢弃；抛弃。例如：The room was littered with discarded newspapers. 房间里到处是乱扔的报纸。4. contaminate v. to make a substance or place dirty or no longer pure by adding a substance that is dangerous or carries disease 污染；弄脏。例如：The drinking water has become contaminated with lead. 饮用水被铅污染了。If you decide to wear medical mask which is pleated and flat like this one, it is important to wear and (Q1) it correctly.
