Didi wendao: "Na shi shenme?"
"It's the Earth. And . . . many stars . . . the moon . . . or the Sun -- oh, I'm not very sure about it," the elder brother said. "But let me tell you about this." He turned to another page, in which they could see a picture of a crane car. (The title in the page is "Truck-Mounted Crane," or 起重機 in Chinese.)
Gege jieshi, shuo: "Zhe shi diqiu. Haiyou, xuduo xingxing . . . han taiyang . . . yueliang -- qishi wo ye bu tai qingchu neige-shi-neige! -- Lai ba! Women lai kan zhe yi zhang." Gege ba shu fan dao lingwai yi ye, zhe yi ye you qizhongji de tupian. (Yingwen mingcheng wei "Truck-Mounted Crane".)
The little brother became even more interested in the elder brother's explanation -- As I can see, they are like a teacher and a student, sometimes!
Didi jujing-huishen ting-zhe Gege de tupian shuoming. Yi wo kan, tamen banyan de fenbie shi laoshi han xuesheng de juese; youshi, tamen jiu xihuan zheyang!
