lung

Human beings and most animals have lungs. It may surprise you that a city also has “lungss”. Rarks in a citry are often referred to as the lungs of the city. The idea is that parks are good places for people to breathe in fresh air.

“You have good lungs” Is a figurative way of expressing the idea that you can produce a great volume of sound. If your lungs are weak, you are unlikely to have a good, sonorous voice,. So a good singer must have good lungs.

肺

人以及大多数动物都有肺。城市也是有“肺”的，你很可能感到奇怪。城市里的各大公园就可以说是城市的肺部，意思是可以呼吸新鲜空气的地主。

You have good lungs是一个形象的说法，指你的声音洪亮。如果肺部不好，你是不可能有优美响亮的声音的，因此出色的歌唱家必须have good lungs.
