【题目】Facts about novel corona virus: Prevention and control
l Keep distance with people when talking
The novel corona virus can be transmitted via droplets and fly 1 to 2 meters in the air before falling to the ground. Droplets can be transmitted far longer when sneezing and coughing than speaking, so apart from keeping 1 to 2 meters of distance, also remember to wear a mask when you are close to someone else.
l Washing hands can reduce risk of getting infected
Please wash your hands promptly and properly after touching elevator buttons or using cash. Do not touch your nose or mouth or rub your eyes before washing your hands. Do not use smart phones while eating.
l Receiving delivered packages at home not dangerous
Though the virus might be attached to the packaging of delivered items, the possibility of transmission through express delivery is extremely low. Before going out to take your delivery, remember to wear a mask. After removing the packaging, please wash your hands.
l Sun exposure cannot kill the virus
The temperature of sun light cannot reach 56℃, and the ultraviolet rays in sunlight cannot reach the intensity of ultraviolet lamps, so the virus can’t be killed by the sunlight. If you want to go out to get some sun, please wear a mask and take other protective measures.
l Taking a hot bath or using air conditioning cannot kill the virus
Although the virus is vulnerable to heat. It can only be inactivated after exposure to a 56°C temperature for over 30 minutes.
l Woolen fabric doesn’t retain virus longer
It is believed that the virus prefers smooth, non-porous surfaces and stays on woolen fabrics for a shorter time. At home or before going out, it is not necessary to consider which kind of material has less chance to absorb the virus—choosing comfortable clothes is enough.
After returning home, please wash your hands, sterilize the clothes and dry the clothes.

在线课程【答案】
【1】A
【2】D
【3】D
【解析】
这是一篇应用文。文章主要介绍了预防和控制新型冠状病毒的方法。
【1】细节理解题。根据Receiving delivered packages at home not dangerous部分下的Before going out to take your delivery, remember to wear a mask.可知，在外出取快递之前，一定要带上口罩。A. Wear a mask.(戴口罩)符合以上说法，故选A项。
【2】细节理解题。l Sun exposure cannot kill the virus部分下的The temperature of sun light cannot reach 56℃, and the ultraviolet rays in sunlight cannot reach the intensity of ultraviolet lamps, so the virus can’t be killed by the sunlight.(阳光的温度达不到56摄氏度，阳光里面的紫外线也达不到紫外线灯里面的强度，所以病毒不能被阳光杀死)可知，紫外线是可以杀死病毒的，只是阳光里的紫外线达不到杀死病毒的强度。D. the virus cannot be killed by the ultraviolet rays(紫外线不能杀死病毒)不符合以上说法，故选D项。
【3】推理判断题。根据文章的主要内容，尤其标题Facts about novel corona virus: Prevention and control(关于新型冠状病毒的事实：预防和控制)可知，本文主要讲述新冠的防御和控制措施，以及一些需要澄清的事实。由此推测，本文很有可能出自一篇科学杂志的文章。D. a science magazine(科学杂志)符合以上推测，故选D项。
