　　[我的发现]

　　(1)例句1为简单句中的省略。

　　(2)例句2为并列句中的省略。

　　(3)第1组例句为状语从句的省略。当状语从句的主语和主句的主语指的是同一人或物，且由人称代词的主格担当，或当状语从句的主语为it，而且从句谓语中含有be动词时，可以把从句的主语和be动词一起省略。

　　(4)第2组例句为关系代词的省略。当关系代词在限制性定语从句中作宾语时可以省略。

　　(5)例句5为不定式的省略。有时可用不定式符号"to"来替代上文中出现的不定式。

　　(6)例句6体现的是当及物动词之后跟由连接词that引导的宾语从句时，that可以省略。

为了避免重复，或为了使句子更简练，在一些句子中常常省去一个或某几个成分，这种语法现象在英语中叫省略。
