再盘旋

In the far distance a helicopter skimmed down between the roofs, hovered for an instant like a bluebottle, and darted away again with a curving flight.

远处有架直升飞机从屋顶上掠过去，绿头苍蝇一样盘旋片刻，再划着圈儿飞也似开走，这便是巡警在窥伺人家的窗户。

They can hover in one spot, hurtle through the air to another location, and then race back to their original hovering point—precisely.

The financial crisis has provided the most recent excuse, if any excuse were needed, for another round of laments that standards are falling, costs are rising, affirmative action has ruined everything; the professors are would-be radicals, the professors are would-be celebrities; the old disciplines are outmoded, the new disciplines are fraudulent; the undergraduates are twittering, their parents are helicoptering; no one is being trained for the global economy, no one is teaching the classics anymore.

新一轮的哀叹接踵而至，如质量下降，学费上升，照顾性做法破坏了一切，教授可能是激进分子或者是爱出风头的明星，传统学科陈旧过时，新学科是骗人的把戏，本科生在上网twittering，他们的父母像直升飞机在头顶盘旋，大学没有训练学生去适应全球经济，没有人愿意再讲授经典等等不一而足。

Instead of attacking more, he hovered in the air on graceful butterfly wings in front of me.

他在我面前优雅地展开蝶翅，在空中盘旋，没有再攻击我。

I believe the silly fellows must have thought they would break their shins over treasure as soon as they were landed; for they all came out of their sulks in a moment, and gave a cheer that started the echo in a far-away hill, and sent the birds once more flying and squalling round the anchorage.

我相信这些愚蠢的家伙们一定以为一到岸上宝藏便垂手可得；因为他们所有的温怒立刻一扫而光，发出的欢呼声在远山激起了回响，再一次地惊起了鸟群，在锚地上空盘旋着惊叫不已。

Many years ago a Griffin king managed to beat the Inferno army because he trained his Griffins to soar in the sky and then drop down on the enemy units like stones.

The wind come my side again at this moment, then the white fox go to me from the back of tree.

在一次偷偷跑出去摘桑葚后，由于贪吃，我落在了伙伴的后面，随着夜幕的降临，我迷路了，夜色中，那阵小小的风再一次出现了，在我周围盘旋一阵后，绕到了一棵大树的后面，接着从大树后面出来一只白色的狐狸。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
