Harrys stomach gave a jolt ; the thestrals head was suddenly pointing towards the ground and he actually slid forwards a few inches along its neck
哈利的胃猛地晃悠一下，黑司兽忽然冲地面垂直飞落，他在马脖子上朝前滑了好几寸。
They were descending at last … he thought he heard a shriek behind him and twisted around dangerously , but could see no sign of a falling body . . . . presumably they had all received a shock from the change of direction , just as he had
终于降落了… …后面传来一声尖叫，他冒险扭头去看，幸亏没有人掉下来… …大概是他们和他一样，都为黑司兽的骤然转向给吓了一跳。
