Adults may look at the months ahead and worry about the election (选举), holiday plans and where their county falls on reopening tiers (等级). Kids just want to know if they are going to get free candy on Halloween. 

Public health officials in the Bay Area have made it clear that activities that may increase the risk (危险) of spreading the coronavirus should be avoided (避免), including door-to-door trick-or-treating and attending (参加) indoor gatherings (聚集). 

 

Stay outside

Many traditional Halloween activities happen outdoors, which is a good thing. Remember to wear a face mask that will protect you from spreading the virus at all times, even if you are outside, as a creepy (令人毛骨悚然的) rubber (橡胶的) mask will not work to slow the spread of COVID-19.  

 

Avoid crowds

The biggest risk on Halloween night will be areas where large groups of people from different households congregate (聚集). That is why governments discourage 

(不鼓励) people from trick-or-treating door-to-door. 

 

There are safer ways to experience Halloween.

Officials suggest setting up a projector (投影仪) outside to watch a scary movie or organizing a socially distanced (有距离的) costume parade (游行) for smaller kids on your block. “I think we need to realize (意识到) that family and friends need to see each other …” said Monica Gandhi, an infectious disease (传染病) doctor and researcher with UCSF.

III. Further reading

Loud music makes it hard for us to focus (集中精力). It seems that mosquitoes feel the same way.

In a study, scientists played loud music inside a cage (笼子) of hungry mosquitoes. At the same time, other mosquitoes were kept in a quiet cage. A hamster (仓鼠) was put in each cage for the mosquitoes to feed on.  

The mosquitoes in the first cage sucked (吸) less blood. They also took longer to start looking for food. 

This study sounds strange, but it might be useful. Mosquitoes spread  diseases (传播疾病) when they feed on people. If the study is correct, people could use loud noise to discourage (阻止) them from feeding and stop the spread of diseases.  

 

•What did the scientists find? 

  Loud music might stop mosquitoes from biting us.

 

•How do mosquitoes act when hearing loud music?

  They suck less blood and take longer to start looking for food.
