During en mass retraction of upper anterior teeth with straight wire technique, the length of anterior hook mainly influenced anteroposterior moving pattern of anterior teeth. As anterior hook increased from 0 to 6mm, labiolingual displacements of lateral incisor varied form lingual tipping to lingual translation and lingual controlling root movement, while 3-D displacements of other teeth only increased in account.

3直丝弓矫治技术整体内收上前牙时，牵引钩的长度主要影响前牙的矢状向位移方式：牵引钩长度增加至6mm的过程中，除侧切牙在唇舌向上由舌向倾斜运动变为舌向整体平移和舌向控根运动外，前牙的三维位移只有数量的增大，趋势基本保持不变。

The sparrow flaps its wings desperately but can't fly, and is tormented until it just closes its eyes and stops moving, strangled by the string. You say that, as a child, you used to catch praying mantises.

用根绳子拴住脚，一端牵在手里，翅膀一个劲直扑打，飞不了的那麻雀，拨弄来拨弄去，临了变闭上眼，一动不动吊死在绳子上。

We ordered the steaks and wine, but it wasn't the same with Hanan watching my glass ('You have to work') and picking stray bits out of my hair while silently miming to me to sit up straighter.

我们点了牛排与红酒，但那是变得不同了，当Hanan看著我的杯子并在我的头发里挑出迷路的食物时无声的对我低语著要坐直一点。

Mort's eyes bored holes in my face. His cheeks began purpling, and his lips quivered. Realizing he was still clutching the gun, I took a step forward. At that, he smiled." I'm not going to shoot you," he said, placing the pistol on histiny desk. Then he knelt, pried a worn rea tile, from the floor to reveal a safe, and began to twist the dial.

罗宾的眼睛无聊的直盯在我的脸上，他的两腮开始变紫，嘴唇边缘在颤抖，事实上，他仍旧紧紧抓住那只枪，我向前靠了一步，这时，他笑了，&我不打算开枪打你&他说，然后，把手枪放在小桌子上，然后他跪下，从地板上撬开一个破旧的瓷砖，露出一个保险柜，他转动上面的标度盘。

That thing turns around at where it is several yards from the shore then submerses.

童博回头一望，也脸色大变，立刻急潜入水躲过那东西，然后化身龙影跃回岸上，那东西在离岸数丈处回转没入水中，掀起的一阵浪直冲上岸，把火堆都打熄了

On the base of keeping the same law of motion of original thread-taking-up pole of computerized embroidery machine and relevant sizes,the disc cam with pushing bar of roller of linear motion along the axis with the spring force closure is used to design a new thread-taking-up mechanism .

保持原有电脑刺绣机挑线杆运动规律和相关尺寸不变，采用对心直动滚子推杆盘形凸轮机构，辅以弹簧力进行锁合，对原挑线机构进行了创新设计

Basing on the theory on Space-Vector PWM, the paper describes the mapping implemented by Neural-Network from tracked voltage vector to turn-on time of IGBT about rectifying sect of direct-driven synchronous generator excited by permanent magnets convertor system.

本文针对直驱永磁风力发电机变流系统的整流部分，利用空间矢量脉宽调制的原理，利用神经网络来实现跟踪的电压矢量到整流器三相桥臂开关时间的映射。

A change had taken place in the weather the preceding evening, and a keen north-east wind, whistling through the crevices of our bedroom windows all night long, had made us shiver in our beds, and turned the contents of the ewers to ice.

头一天夜里、天气变了，刺骨的东北风，透过寝室窗门的缝隙，彻夜呼呼吹着，弄得我们在床上直打哆嗦，罐子里的水也结起了冰。

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。
