【简答题】
《We Are All Fighters》 This is a war! It's a war without guns, bombs, or smoke But it's a war with virus, doubts, fears, rumors, and discriminations. But we shall all be fighters, my dear fellows! Not just the doctors, the nurses, the policemen and the scientists who should fight All of us should be the fighters in this war We shall fight against 1 We shall fight against uncertainty We shall fight against doubts We shall fight against 2 We shall fight against rumors We shall fight against discriminations This is going to be a fierce and 3 war But don't be afraid, We're going to win this war together in the end! Our people may get sick, our city may get sick, but we as a 4 nation, will never ever get sick Because we have the history, spirit and 5 to win. We've been on this planet for over 5000 years. We've witnessed much darker moments We've been through much crueler trials No matter it's the war, invasion, starvation, poverty or 6 We've always survived and We've always stood back up on our feet We've always won in the end. And we will 7 win this time. We don't know how long this will take, Or what cost we have to pay But there's one thing we are 100% sure That is: we are going to win this war in the end! Because that’s what we've been doing for the past 5000 years. And that's what makes us 8 ever It is only by going through dark times that we can separate the greatest from the great. In each dark time, We’ve always fought together No matter how strong our enemy was Or how 9 it seemed to win We just kept fighting Because we are all fighters! When all of this is over, we’ll have another great and heroic story to tell our children, our grandchildren and they will tell the next 10 . That's how we'll pass this great spirit on, and keep it alive forever!
