VOA慢速英语:Experts Say as AIDS Epidemic Changes, So Should Prevention Efforts

level off使平稳; 使稳定

例句：On reaching 1000 meters, the pilot leveled off.
       到达1000米高度时, 驾驶员便做水平飞行。

      After going up for six months, the cost of living leveled off in September.
      生活费用上涨了六个月以后于九月份稳定下来。

这里要注意了，虽然有个off在这里，但是是稳定的意思，本人已开始差点以为是水平下降的意思！
