Before humans were sent up in the balloon, a test flight was made using three animals: a sheep, a duck, and a rooster.
在热气球载人飞行之前，首先进行飞行试验的是三只动物：一只羊，一只鸭子和一只公鸡。A year later he was the first person to fly over the Atlantic in a hot air balloon. He ballooned across the Pacific in 1991.
一年之后，他又成为第一个乘坐热气球穿越大西洋的人。The fireball is no longer luminous but it is still very hot and it behaves like a hot-air balloon, rising at a rapid rate.
火球不再明亮，但它还很热，并且象一个上升得很快的热气球一样。So before men would go up in a balloon, they would first float (or send up) a trial balloon without any men in it to test the situation.
所以在人进入热气球之前，他们会把一个没有人的热气球用作实验来探测环境。Everybody sitting in a basket, and I was on top of the balloon, ready to slide down with my skysurf board.
所有人都待在热气球的架子里，我则在热气球的顶端，准备从顶端用高空滑板上滑下。The hot air balloon took off. It was as buoyant in the air as a cork in water.
（热气球起飞了，它在空中漂浮着就象水中木塞一样。）尽管不认识。The hot-air balloon took off. It was as buoyant in the air as a leaf in water.
把热气球升在空中比作叶子在水中，可猜出buoyant是“漂浮”的意思。But actually I had to go around the world in a balloon to be invited to talk about it.
但其实我不得不乘着热气球环游世界以便获得邀请谈论它。Dee, Sam, Ellie Linda and Ian have promised, if necessary, to carry me on board the balloon. I cannot miss this.
迪伊、山姆、艾莉.琳达和艾恩答应我，如果实在不行，他们会把我抬到热气球上，我决不能错过这个机会。
