典型例题

　　My dictionary ___, I have looked for it everywhere but still___ it.

　　A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.

　　答案D. 前句是一个仍在持续的状态，应用进行时，由于没有找到，其影响仍然存在，应用完成时，瞬间动词用于否定式时可用于完成时。

　　e:现在进行时有时可以用来表示赞叹或厌烦的感情.例如:

　　He is always causing trouble.

　　他总是惹麻烦.

　　The Present Continuous Tense 现在进行时

　　现在进行时最容易出现错误的地方在动词的现在分词形式，我们在复习的时候要特别注意不规则动词的变化形式。

　　例如：

　　taking，taking是take的ing形式,以e结尾要去e加ing;

　　swimming，beginning，putting, shopping, stopping, hopping, travelling 要双写最后一个字母,之后加ing;

　　buying,playing,teaching,等大部分单词直接加ing.

　　有一些特殊变化(或者说以Ie为结尾的重读闭音节的动词)的现在分词〔有3个〕,:lying—lie, dying ―die tying―tie 这些以ie结尾要去e再把I变y再加ing.
