到...的时候

And I studied when we use the rudder we should make the aileron have a little movement opposite to keep the aircraft straight.

不过我学到了以前并没有注意到的东西，就是我们在使用方向舵的时候，需要同时往反方向轻微的改变副翼的构形。这样有利与保持飞机的姿态。

One old hunter who has a dry tongue, who used to come to bathe in Walden once every year when the water was warmest, and at such times looked in upon me, told me that many years ago he took his gun one afternoon and went out for a cruise in Walden Wood; and as he walked the Wayland road he heard the cry of hounds approaching, and ere long a fox leaped the wall into the road, and as quick as thought leaped the other wall out of the road, and his swift bullet had not touched him.

有一个老猎户，说起话来枯燥无味，常到瓦尔登湖来洗澡，每年一回，总在湖水最温暖的时候到来，他还来看我，告诉过我，好几年前的某一个下午，他带了一枝猎枪，巡行在瓦尔登林中；正当他走在威兰路上时，他听到一只猎犬追上来的声音，不久，一只狐狸跳过了墙，到了路上，又快得像思想一样，跳过了另一堵墙，离开了路，他迅即发射的子弹却没有打中它。

She was within three steps of the bottom; she already heard Morrel's voice, when suddenly a cloud passed over her eyes, her stiffened foot missed the step, her hands had no power to hold the baluster, and falling against the wall she lost her balance wholly and toppled to the floor.

她走下楼梯，当还只有三级楼梯未走完的时候，她已经听到莫雷尔的声音，但突然地，她眼前一阵发黑，她的脚摇摇晃晃地踩不到踏级，她的手无力握住栏杆，她撞到墙上。

These students manage to study there without being dumb enough to put their friends and colleagues in danger, or to engage in such ridiculous activity as wearing "native disguises"(apparently Ms. Borger isn't aware that the need to dress in disguise to travel around Asia disappeared about the same time as the British Empire).

这些学生能学会在那里学习而且不会愚蠢到置他们的朋友和同事于危险之中，或者做出像穿着"本土伪装"的荒谬举动（看来Borger小姐没有意识到在亚洲旅行需要乔装打扮的做法大约在大不列颠帝国的时候已经消失了）。

The spat began when Mears, who founded a bushcraft school 25 years ago, laughed out loud in a Radio Times interview after being asked if he watched his rival's programmes to pick up survival tips.

他们之间的争执起源于雷胖子在一次电台节目采访中被问到他时候通过观看他的对手的节目学到一些个生存技巧时的哈哈大笑，雷胖子在25年前建立了丛林求生学校。

During this break in the proceedings Pierre noticed that Prince Vassily moved away from his chair-back, and with that same air of being quite sure of what he was about, and of its being so much the worse for others, if they failed to understand it, he did not go up to the sick man, but passed by him and joined the eldest princess.

在暂时休息的时候，皮埃尔看见，瓦西里公爵从椅子背后走出来，那神态表示，他心里知道应该怎样行事，假若别人不了解他，他们的处境就更糟了，他没有走到病人跟前，而是从他身边经过，他去联合公爵的大小姐，和她一起走到寝室深处挂有丝绸帷幔的高高的卧榻那里去了。

It is like gold, or more exactly it is like the golden-coloured semi-precious stone which one sometimes sees in signet-rings, and which I think is called a chrysoberyl.

这时你会注意到你在其它时候注意不到的一点：蟾蜍大约生着一切生命体中最美丽的眼睛，像金子一般，或者更准确地说，像金色的半宝石一般，就是有人会镶嵌在图章戒上、我想是叫作金绿玉的那种。

The wind rose, and from a fresh breeze it soon increasedto a regular gale; that is to say, it acquired a speed of from forty toforty-five miles an hour, before which a ship in the open sea would haverun under close-reefed topsails.

风愈刮愈大，很快就由微风一变而为正式的暴风了；它的速度达到每小时四十到四十五英里，船如在海里遇到这种风，即使紧收着中桅的帆，也会象飞似的前进的，乘风破浪号在将近六点钟的时候到了港湾口，可是这时候潮势变了，因此它不能入港。

The wind rose, and from a fresh breeze it soon increasedto a regular gale; that is to say, it acquired a speed of from forty toforty-five miles an hour, before which a ship in the open sea would haverun under close-reefed topsails. Now, as it was nearly six o'clock when the"Bonadventure" reached the gulf, and as at that moment the tide turned, itwas impossible to enter.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
