在空中

For when things are once come to the execution, there is no secrecy, comparable to celerity; like the motion of a bullet in the air, which flies so swift as it outruns the eye.

情况一旦进入实施执行阶段，跟快速相比，就没有秘密可言；如同子弹在空中的动作，它飞得这样快，非人的眼力能及。

Migration parameters for the overflying population - density, speed, direction, flux, collective orientation - and their variances are estimated from these datasets, and profiles of these quantities can be obtained by the usual scanning entomological radar technique of observing at a sequence of antenna elevations.

利用该系统可以获得昆虫在空中迁飞获动的密度、速度、方向、群体定向及变化情况。进行按一定仰角的系列观测，即可获得各个高度层昆虫迁飞分布的情况。

He then ordered the plane back up in the air and parachuted out somewhere over southwestern Washington.

然后，他下令乘飞机返回了在空中跳伞出去了西南华盛顿。

In today's experiment we will build a simple parachute and learn about the forces that keep parachutes in the air.

今天的实验中，我们将自制一具简单的降落伞，并了解降落伞在空中飘浮的原理。

I think it pervades the open air, waiting at all times

我想它正弥漫在空中，永远等待着

Dozens of butterflies in brilliant hues and patterns to rival a Missoni gown flitted along the trail, while Jurassic Park–size earthworms and millipedes slithered into damp ravines, and pairs of gray parrots pirouetted in the sky.

许多各色各样的蝴蝶飞向小路的前方，巨大的蚯蚓和爬虫钻进峡谷，成对的灰鹦鹉在空中翩翩起舞。

She asked, dipping her camel's-hair brush into the wet aquamarine upon the palette, and poising it carefully before putting in the delicate streak of purple which was to brighten the horizon in her pupil's sketch.

她问道，一面将驼毛画笔蘸到调色板上潮湿的海蓝颜色里，接着，画笔谨慎地虚悬在空中，迟迟未落到学生的速写中那一抹柔和的紫红色里，使地平线明朗起来。

The brilliant boxing gloves moving in the sky and the poops from the collision among gloves mean the exchange of friendship and technology and the communication of civilizations and hearts.

舒适的环境，热烈的气氛，汗流浃背的身躯，舞动在空中鲜艳的拳击手套，手套与手套间碰撞发出的啪啪声……是友谊与技术的交流，是文明与心灵的沟通。

The excitement filled the air and people couldn't have been any prouder of Chinese athletes.

激动的情绪在空中回荡，人们为中国的运动员们感到一种前所未有的骄傲。

Li, punctuating the air with her hands, her fingernails decorated with pink rose decals.

一边说着，一边用手在空中一挥，指甲上还画了粉红玫瑰图案。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
