ZC8T5I4X10G5名师精编优秀教案适宜于跨海。将来在很深的水里造桥，不必把桥墩沉到江底，而把桥墩做成空心的箱子，让它浮在水中。桥上无车时，它就浮得高些，桥上有车时，它就浮得低些。这些高低当然不能相差过多，以免行车困难。同时，还要把各孔桥梁，从桥的这一头到桥的那一头，牢固地联系在一起，使整个桥梁成为一体，车在上面走，不致颠簸不稳。1选段中加点的“一定”、“约”两个词能不能省去，为什么？答：2第一段中运用了哪能说明方法，有什么作用？答：3试归纳选文的中心与层意。答：参考答案：说明对象：桥梁远景图2、D 4、：运用作比较的说明方法，把桥与板凳相类比来说明桥的结构；还运用了分类的说明方法，分别说明了桥梁、桥墩、基础三要素5、将会有可以弯曲的桥、很小很轻便的桥、无梁飞渡的桥。能力训练：阅读、不能省去。“一定”表示将来肯定会有没有水中桥墩的大桥，而“约”表明三公里只是一个大概的估计。如果省去，说明语言就不严密准确了。运用了举例子和例数字的说明方法，通过举黄河铁路桥的例子，来说明将来没有水中桥墩的大桥的远景，运用列数字说明桥的长度，这样起到了具体准确说明事物的作用。选文的中心是：将来一定会有没有水中桥墩的大桥。一层（1 段）：介绍江中没有桥墩的大桥。二层（2 段）：介绍桥墩浮在水中的大桥。文档编码:CP7K5G10S2C6 HC2Y1R4M5X7 ZC8T5I4X10G5文档编码:CP7K5G10S2C6 HC2Y1R4M5X7 ZC8T5I4X10G5文档编码:CP7K5G10S2C6 HC2Y1R4M5X7 ZC8T5I4X10G5文档编码:CP7K5G10S2C6 HC2Y1R4M5X7
