“鲍勃,你今天已经四岁了,”一天爸爸说道,“你这个年龄可以去动物园了。”鲍勃说,“啊,我想去!”爸爸答应了,但要鲍勃跟着他和马克一起去。“好的,”鲍勃回答说。在动物园里,鲍勃紧紧地贴着爸爸,寸步不离。他们首先去看狮子。他们见一头母狮静静地躺在那里,一头幼狮躲在她身后。接着,这头幼狮跳了出来,向另一头幼狮扑了过去。然后这头幼狮又躲了起来。他们戏戏耍耍,蛮开心的。 “Bob, you are four years old today,” one day father said. “You can go to the zoo at this age.” Bob said, “Ah, I want to go!” Dad promised, but Bob followed him and Mark. “Okay,” Bob answered. In the zoo, Bob clings to his father tightly. They first went to see the lion. They saw a lioness lying there quietly, and a lion cub hiding behind her. Then the cub jumped out and rushed toward the other cub. Then the lion cub hid again. They play games, very happy.
