knock over: 弄翻；撞倒

美国网球公开赛女单比赛继续进行，头号种子、俄罗斯选手莎拉波娃以2比0轻取来自马达加斯加的兰德里安特菲，顺利晋级第三轮。比赛刚开始时，莎娃对于大风天气有些不适应，她在头两局都出现了发球双误的情况，不过随后她调整了状态，最终只用了49分钟就击败对手过关。请看外电报道：

Wispy Maria Sharapova was one strong gust away from getting knocked over, though not out, at the U.S. Open.

"I'm really glad I had a piece of chocolate cake last night," she joked, "otherwise I would have been blown away. It made me heavier."

Nearly as thin as her racket, the top-seeded Sharapova had more trouble with gales up to 36 mph playing tricks with the balls than she did with any of the shots by Dally Randriantefy in a 6-1, 6-0 rout Wednesday that took all of 49 minutes.

文中的knocked over/down意思是"弄翻；撞倒"，如：She was knocked over/down (=hit so that she fell to the ground) by a hit-and-run driver/ a truck.（她被一个/一辆闯了祸就逃的司机/卡车撞倒了。）又如：Who knocked over this vase?（谁把这个花瓶打翻了？）
