桥

A bridge would cost far more than a tunnel, but you would be able to go by rail or by car on a bridge, whereas a tunnel would provide a rail link only.

建桥的成本远远超过修隧道的成本，但在桥上可以行驶火车或汽车，而隧道则只能提供铁路交通。

This time you're not the driver of the trolley car,you are an onlooker.you are standing on a bridge,overlooking a trolley car track,and down the track come the trolley car, at the end of the track are five wokers.the brakes don't work.the trolley car is about to crash into the five and kill them.and now you are not the driver,you really fell helpless.until you notice standing next to you,leaning over the bridge is a very fat man.and you could give him a sholve,he will fall over the bridge onto the track.right in the way of the trolley car.he would die but he would spare the five.now how many would push the fat man over the bridge .raise your hands.

现在，你不是电车司机，你是个旁观者，你站在桥上，俯瞰电车的电轨，沿着轨道尽头有5个工人。电车手刹照样不灵了。电车快要撞向这5人。你不是司机，你真的感觉很无助。突然，你看见站在你旁边，桥边还有一个非常胖的人，你可以推他一把，他会掉到轨道上，刚好能停住车。他会死去，但能救活其他5个人。有多少人会推那个胖子？

The first cross sea pontoon in the world-Da Xie Bridge, Ningbo, Zhejiang; Merowe Pontoon over the Nile, Ningbruss Pontoon over Congo River in Africa, Ktihat Pontoon in Nepal, 200T ferry in Sudan, Kelimu Pontoon in Xinjiang, and trestle of Minsk aircraft carrier in Shenzhen are functioning as the business card of our company in the civilian pontoon market. The series of suspension bridge of southeast hydraulic power plant trestle, Hangzhou Bay bridge trestle, Jiaozhou Bay bridge trestle and segmental bridges in Burmese and Ecuador have won high appraise from the owners.

世界上第一座跨海浮桥——浙江宁波大榭桥、尼罗河上的麦洛维浮桥、非洲刚果河上的英布鲁浮桥、尼泊尔的可迪亚哈特浮桥、苏丹的200吨渡船以及新疆的塔里木浮桥、深圳明斯克航母栈桥等，成了我公司在民用浮桥市场的名片，以西南水电站用栈桥、杭州湾大桥栈桥、胶州湾大桥栈桥和缅甸、厄瓜多尔等国的拼装式吊桥为代表的系列吊桥、装配式公路钢桥得到了业主的高度赞扬。

The trail bridge design,the mixture performance test,the temperature between the different layers of the deck surfacing,the traffic investigation and the surface performance observation are introduced in this article.The basic performance of the mixture used in the trial bridge is analyzed through rutting tests at high temperature,bending tests at low temperature,fatigue tests of the composite beam and pull off tests.The rule of the temperature gradient distribution in the pavement and the variety relation ...

介绍润扬大桥钢桥面铺装试验桥的方案设计、试验研究、温度测试、交通量调查和使用性能跟踪观测，通过混合料高温车辙试验、低温弯曲试验、复合梁疲劳试验以及拉拔试验等分析实桥试验沥青混合料基本性能，阐述铺装内各层温度梯度分布规律及与大气温度变化关系，通过使用性能跟踪观测介绍浇注式沥青混凝土+环氧沥青混凝土新型铺装结构的工程效果。

The conclusions are: The sonic velocity determined by the material's properties is the upper limit of the crack velocity; Bridging fibers plays a key role in increasing the composite's toughness and stopping the crack's propagation; The semi-infinite crack propagating in infinite region with the fiber bridging traction action is equal to the semi-infinite crack propagating in strip.

结论有：(1)由材料性能决定的音速是裂纹传播速度的上限；(2)桥联纤维在增韧复合材料和组织裂纹扩展中起了关键作用；(3)受桥联纤维力作用的半无限长裂纹在无限域中扩展等效于半无限长裂纹在带域中扩展。

The town was built near a bridge on the River Cam : hence the name Cambridge .

这座城镇建在康姆河上一座桥的附近，因此而得名为康桥

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.
