He loved them so much and he ordered the best falconer to train then to fly.After several months, the king came to see how the training was

10、going on. He found that one falcon had already been able to fly high in the sky, while the other was staying on the branch(树枝) of a tree quietly, just keeping still.The king called all his falcons together and ordered them to try every way they could to make the other falcon fly.

15、内容,本期继续刊登该文对于今后拱桥的发展方向内容部分。5 h$ u N/ s1 c: m0 p& X发展方向工程应用拱桥在历史上曾最主要的大跨度桥型,在世界范围内得到广泛的应用,在我国更是如此。随着高强、大跨索结构的发展,拱桥的跨越能力已相对下降。在跨径超过300m的桥梁中,一般情况下斜拉桥具有更强的竞争能力。而在200m跨径以下,现代预应力连续刚构因其施工优势而受到欢迎。因此,拱桥的竞争能力已较过去有很大的削弱。应该说,作为引领桥梁技术进步的拱桥时代已经过去。然而,拱桥仍然是重要的桥型之一。对于广大的山区、海岛等地区和地质条件好的桥位,拱桥仍是具有很强竞争力的桥型,如前述我国的合江长江一桥。

16、对于活载比重较大、动力问题较为突出的高速铁路,拱桥的优势更显突出。前述的几座大跨度拱桥,大部分是高速铁路上的桥梁,如中国的大胜关大桥、北盘江大桥、南盘江大桥、宜宾金沙江公铁两用桥、鸭池河大桥。印度的Chenab桥,西班牙的Almonte大桥。德国近年在修建高速铁路VDE8柏林联接纽伦堡和慕尼黑的线路中,也大量采用了混凝土拱桥。在一段跨越森林的线路中,29座跨谷桥梁有10座采用了混凝土拱(跨径为90m到270m)。具体到三种桥型,混凝土拱桥因自重大,主要仍将应用在地质条件较好的地区,在200m以下,施工技术较为成熟,材料与结构创新将提高其经济跨径。钢拱桥由于强度高,自重轻,跨越能力强,施工难度小

17、,在超大跨度应用时最具优势,如超大跨度的高速铁路拱桥,或地质条件较差的大跨度拱桥。此外,在造型景观要求较高的人行桥、景观桥中,钢拱桥对特殊结构的适应性强、施工难度小,也仍将有大量的应用。对于钢管混凝土拱桥,它仍将在我国得到不断的应用。同时,国外的应用也在增加,近期美国内布拉斯加州公路局也采用钢管混凝土系杆拱桥,通过使用高强钢材和混凝土使结构的自重更轻,从而可以通过普通起重机械安装更大的拱截段,以取得既能快速施工、建成后又美观的效果。跨径突破从跨径来说,2000年以来,几种拱桥的跨径的突破均不大,钢拱桥从卢埔大桥的550m到重庆朝天门大桥的552m,突破2m;混凝土拱桥从万县长江大桥的420m到

18、北盘江大桥的445m(在建),将突破25m;钢管混凝土拱桥从巫山长江大桥的460m突破到合江长江一桥的530m,突破70m。预计在短期内,这些跨径不会有大的突破。钢拱桥是跨径可达千米以上的一种可能的桥型。对于研究超越现有跨径的钢拱桥具有重要的意义,尤其是当高速铁路需要超大跨度桥型时。然而,大跨径钢拱桥在道路桥梁中已丧失经济上的竞争力,因此在实际工程应用时,对超越现在的跨径应持慎重的态度,为记录而记录的倾向应该制止。对于混凝土拱桥和钢管混凝土拱桥来说,它们还具备向更大跨径发展的潜力和必要性,关键要在材料、结构和施工方法方面开展研究。相比较而言,钢管混凝土拱桥跨径突破的潜力要更大些。新材料、新结构

19、的应用在材料方面,高性能与超高性能混凝土在拱桥中的应用是一种必然的趋势。超高性能混凝土在世界上已应用于三十余座桥梁,我国仅在一座铁路桥上应用,目前有一座公路桥梁在建。研究表明,梁式结构较难发挥超高性能混凝土的超高强度,拱才是最理想的应用结构。然而,这三十余座桥梁中,目前拱桥只有二座。究其原因,在于国外混凝土拱桥因修建数量少,缺乏大型缆索吊装设备,以悬臂浇筑为主,而超高性能混凝土一般需要蒸汽养护,因此实现困难。相反,我国的混凝an idea came to his mind. Maybe someone who knew the natural environment well could so

20、lve this problem. He spent for a farmer who lived in the forest into his palace to train it at once.The next morning, the king saw the other falcon flying above in the sky freely. “ it is unbelievable !” shouted the king. How could you make it happen?”The farmer replied,“Its very easy. I just cut of

21、f the branch where the falcon rested.”It is always the same to human beings. We all have “two flying wings” in our hearts as well, but we often seem not to notice them and stay where we just for safety and comfort. We wont realize we can fly so high and freely until the “branch” we are resting on br

25、 is little doubt that house cat first developed naturally from ancient wild cats. The cleverest relative is the America wild cat which still lives in Africa today. This is understandable because the first house cats came from Africa. Cats first started to live around people in Egypt about 6,0007,000

26、 years ago. From Egypt, cats started to move around the world. This is about the same time that Egyptians began storing grain(谷物)in buildings. Scientists used to believe that people tamed cats to catch mice and protect the grain. However, cats dont like to be told what to do! Now, scientists believe

27、d that cats followed the mice and learned to accept people. Finally, some of the cats began to grow comfortable around people, these were smaller cats that needed protection. As these cats and people got used to each other, then they moved in together. Around 5,000 years ago, cats started to live wi

28、th people. Soon cats were in Greece, then the Middle East and China. They moved along Egyptian business roads keeping away mice and keeping people around them. After the Romans came to Egypt, they also accepted the cats and brought them to Europe. These cat likely bred(繁殖) with other cats to form th

29、e many kinds of house cats we have today. Cats are relatively recent house animals. House cats still have a lot in common with their wild relatives. Cats sleep a lot to save energy just like wild cats. They will often get food at night as well. House cats are generally peaceful and friendly, but be

30、careful! If a cat feels it is in danger, it will fight backjust like a wild cat.根据材料内容选择最佳答案。51.Where did the first house cats come from? A.Asia. B. Africa. C.Europe. D.America.52.When did cats start to live with people? A. About 4,000 years ago. B.About 5,000 years ago. C.About 6,000 years ago. D.About 7,000 years ago.53.According to the text, which of the following is TRUE? A.Cats started to move around the world from China. B.Cats get food at night to save energy like wild cats. C. Cats have a little in common with their wild cats. D.Cats were accepted and brought
