【TPO例句】

1. It attracts the water droplets, sucking them into the tiny pores. (TPO44-L1)

它吸收水滴,把水滴吸入自己微小的孔中。

2. What that does, is burn the polymer away, and fuse the silicon nano particles together, while maintaining the structure of pores.(TPO44-L1)

这种方法所做的是:燃烧聚合物,把硅纳米粒子融合在一起,并且同时保持孔结构。

3. The majority of petroleum is just filling in the tiny pores and cracks in rocks.(TPO50-L4)

大多数石油仅仅就是填充在岩石里小的孔洞和裂缝中的。

4. Even the pores in the wall are filled with water, which almost stops the diffusion of gases.(TPO47-P2)

就连墙壁上的小孔里都充满了水,这使得空气几乎无法扩散。

5. Most of the world’s potable water----freshwater suitable for drinking----is accounted for by groundwater, which is stored in the pores and fractures in rocks. (TPO28-P1)

世界上绝大部分饮用水----可以饮用的淡水----都是地下水,它们储藏在岩石孔隙和裂缝中。

6. At greater depths within Earth, the pressure of the overlying rock causes pores and cracks to close, reducing the space that pore water can occupy, and almost complete closure occurs at a depth of about 10 kilometers. (TPO28-P1)

随深度增加,上覆岩层压力使岩石孔隙和裂缝闭合,减少了水的储存空间,而超过10公里深的地下孔隙几乎全部闭合。

7. The water table is the underground boundary below which all the cracks and pores are filled with water. (TPO28-P1)

地下水位指地层岩石裂缝和孔隙充满水的边界。

8. They possess drought-resisting adaptations: loss of water through the leaves is reduced by means of dense hairs covering waxy leaf surfaces, by the closure of pores during the hottest times to reduce water loss, and by the rolling up or shedding of leaves at the beginning of the dry season. (TPO26-P2)

这类植物进化出了抗旱适应机制:覆盖在蜡质叶子层表面的浓密的绒毛,在温度最高的时候闭合气孔,在干旱季初期卷起或脱落叶片都可以减少经过叶片的水分的流失。

9. They include roots or root like structures, a waxy cuticle that covers the surfaces of leaves and stems and limits the evaporation of water, and pores called stomata in leaves and stems that allow gas exchange but close when water is scarce, thus reducing water loss. (TPO25-P3)

其中包括根或者类似根的结构、覆盖茎叶表面能阻止水分蒸发的蜡质角质层以及茎叶上被称为气孔的小孔——气孔的存在可以保证气体的交换,并在水分缺失时关闭气孔从而防止水分的进一步流失。

10. So much for unconsolidated sediments. Consolidated (or cemented) sediments, too, contain millions of minute water-holding pores. (TPO1-P1)

以上说的都是松散的沉积物,那些坚固的沉积物,也拥有以数万计的毛细孔来容纳水。

v. 仔细阅读;认真钻研
