【答案】How I have Changed  COVID-19 pandemic has made a great difference to our life.In the past，we used to go out without wearing masks.Now，we are asked to wear masks wherever we go.People used to shake hands when meeting each other.Now people try not to do so.Instead，they touch their arms.Our school life has changed too.We are asked to wash our hands more often.We should often take NAT .When we go to public places，we should show our health code and travel code.We have to have lessons with masks on.Sometimes when the situation gets serious，we have online classes.
I think it is necessary for us to change our lifestyle.We need to keep healthy.After all，we can't be happy without good health.We should try not to go out.If we have to go out，we must wear a mask.We shouldn't go where there are many people.
