时间状语从句和原因状语从句
教师寄语：功夫不负有心人 Everything comes to him who waits. ?? ★请大家举例状语:
状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。
例如：
1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语)
3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词)
5. I know how to light a camp fire because I had done it before .（原因状语从句）
状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。

根据管道机器人的不同驱动模式，大致可以分为八种。
第一种是流动式机器人，这类机器人没有驱动装置，只是随着管内流体流动，
属于不需要消耗能源的被动型机器人，但是其运动模式相当有限。
第二种是轮式机器人，这一类机器人广泛运用于管道检查工作，目前许多的商业机器人就是这一类型。
第三种是履带式机器人，即用履带代替轮子。
第四种是腹壁式机器人，这类机器人通过可以伸张的机械臂紧贴管道内壁，推动机器人前进。
第五种是行走式机器人，这类机器人通过机械足运动，但是这类机器人需要大量驱动器，并且难以控制。

第六种是蠕动式机器人，这类机器人像蚯蚓一样通过身体的伸缩前进。 第七种是螺旋驱动式，即驱动机构做旋转运动，螺旋前进。 第八种是蛇型机器人，这类机器人有许多关节，像蛇一样前行。
