dig 、scoop和 shovel的区别

dig 是普通意义上的“挖”

scoop是大幅度的挖，用手做大动作的“捞”也叫scoop.你应该可以体验到这个动词与dig不同的地方。

shovel 专门指用铲子挖，也可引伸于把一些东西从一处铲到另一处。

英语中过去式和过去分词的区别&运用分别是什么？都用于什么地方？谢谢了。

过去式一般构成过去时态，过去分词构成完成时态和被动语态。它们的构成非为规则构成和不规则，规则的在动词后加-ed.,不规则的要死记。规则的就直接加ed就可以了，动词过去式变化规则:

1．规则动词过去式过去分词的变化规则

1）一般在动词词尾加ed。

work—worked,rain—rained,watch—watched

2）如果动词以字母e结尾，变过去式时直接在词尾加d。

3）如果动词是以一个元音字母加上一个辅音字母结尾的重读闭音节单词，变过去式时，要双写这个辅音字母，再加ed。
