是英语吗？增加字数，对吗？常用方法如下：

1. 给名词前后增加修饰成分。比如a room--a big room with two doors(看见room前后增加的词或短语了吗？)形容词还可以采用并列，比如a big room--a big and beautiful room。名词后面还可以是定语从句。

2. 给动词增加副词，比如study--study hard--study hard and diligently.

3. 根据前后逻辑关系，增加内容，从而增加字数。比如Tom studies hard. He is a nice boy--Tom studies hard. So he is an excellent student in our class. He is a nice boy. He is very polite(礼貌) and everybody likes him.
