Further up the food chain , there are bigger animals like cows and camels or koalas which also use bacteria in their stomachs to break down plants 食物链的再上一层，便是更大的动物，如牛，骆驼或树袋熊，他们同样用其胃里的细菌分解植物。
They were waiting for me after school for a number of afternoons to follow . i tried varying my routes and avoiding bushes and hedges . it usually didn ' t work 接下来的几天，每逢下午放学，他们都会在半路上截我。我试着改变回家的路线，不走有灌木丛或树篱的地方。但基本上没用，他们总是能拦住我。
You can then add navigation controls to your asp . net pages that can automatically create a menu or tree view of links to pages , or that can display a " breadcrumb " showing the current page hierarchy 然后可以向asp . net页添加导航控件，这些控件可以自动创建页链接的菜单或树视图，或可以显示当前页的层次结构（称为“面包屑” ） 。
The sort of advances that will really change the world , such as ethanol that can be made cheaply from grass or trees , or solar cells that can be painted onto almost any surface , remain a distant prospect 而那些真的能改变世界的技术进步，比如用廉价的草或树制造酒精，或是可以安装于任何物体表面的太阳能电池，还是一个遥远的梦想。
Firstly , singly linked lists are used as the data structure of this algorithm rather than doubly linked lists or trees as other algorithms use , so less memory space and running time are required . secondly , the relationship between the entry and exit points on the two polygons is found and argumentation , which , with the reasonable operations on the lists , reduces the times that the lists are traversed and allows the polygon to be input clockwise or counterclockwise 该算法使用单线性链表数据结构，与其它使用双链表或树结构的算法相比具有占用空间少及处理速度快的特点；其次，找出并论证两个多边形之间进、出点之间的关系，并通过合理的数据结构处理，减少了算法对多边形链表的遍历次数，而且允许多边形既可以按顺时针方向也可以按逆时针方向输入。
In the course of designing reasoning machine , this article uses forward inference and the tactics of best - first search . and in connection with much of fuzzy knowledge , it introduces confidence theory to infer the formula of confidence which propagate in and / or tree , and illustrates how to calculate the confidence when it propagate in the course of automobile components failure analysis reasoning 在推理机的编制过程中，本文采用了正向推理方法及最好优先搜索策略，同时针对知识库中大量的模糊知识，本文引入了可信度推理模型，推导了可信度在与或树中传播计算公式，并举例说明了在汽车零部件失效分析推理过程中可信度的传播计算方法。
