扩句的方法在学习扩句法之前，先对学生进行五个简单句句型，并列句和复合句的专项训练，打好基础。
扩句是在基本句型的基础上，添加各种修饰成分，使句子得到扩展，即根据表达的需求增加定语，状语，同位语等成分，或者举例子补充细节内容，或者添加谚语俗语等。
1 1. We arrived in Sanya.----- We arrived in Sanya, happily and excitedly. (添加副词)2 2. I like to make friends with my classmates.------ I like to make friends with my classmates, who have the same interest as mine. (添加定语从句)3 3. We were happy and returned home.------- We were happy and returned home after we had finished collecting all the rubbish.(添加状语从句)4 4. I like reading books.------- I like reading books, such as novels, short stories, magazines and newspapers.(通过举例补充细节)5 5. We should study hard.-------- As we all know, “Practice makes perfect”.So we should study hard.（添加谚语）6 6. I often join in many activities.-------- I often join in many activities in order to communicate with other students and broaden my mind. (添加目的状语)三．具体应用试题要求：假如你是一名中学生，请以My colorful school life为题，写一篇短文。
要求100个字左右。
开头和结尾已经给出，不计入总数。
要点提示：1：上课认真听讲2：课后完成作业3：经常参加体育锻炼4：去图书馆阅读I’m a high school student and I understand what I’m studying for. I have been working hard.___________________________________________________ ____________________________May there always be colorful life around my school.学生的习作：I’m a high school student and I understand what I’mstudying for. I have been working hard.I listen to the teacher carefully. I finish my homework after class. I often take exercise. I often read in the school library.May there always be colorful life around my school.点评：该学生能完整的写出各个要点，没有出现太大的语法错误，表达通顺，单词拼写无误。
但是很明显字数不够，没有达到100个字左右，字数不够是很多学生面临的共同问题。
其次，句子的表达过于平淡无奇，没有句式多样化和使用高级词汇，固定搭配、固定短语等使表达地道。
而且，没有使用连接词，上下文的连接不够顺畅。
改进方法：步骤一：列要点把要写的内容要点化，做到要点齐全。
1: Listen to the teacher carefully2: finish my homework3:take part in exercise4: often read in the library步骤二：造简单句充分利用五个简单句句型对各个要点进行补充，使其变成一个完整的句子。
每个句子都要注意句子成分的完整性，语法是否正确，说法是否符合英语表达习惯。
1: I listen to the teacher carefully in the class.2: I finish my homework after class.3: I often take part in exercise with my classmates.4: I do some reading in the school library.步骤三：扩展句子1: I listen to the teachers carefully in the class so that I can understand what the teachers say.(增加目的状语从句)2: I finish my homework after class, which is a piece of cake for me.（增加定语从句）3: I often take part in exercise with my classmates, such as playing football, going swimming andplaying badminton etc.（举例说明）4: I often do some reading in the school library when I have nothing to do after class.（增加时间状语从句）步骤四：润色句子根据高考（海南）英语作文评分细则，第五档的要求：24-25分，至少有3个复杂句，2种从句形式，语气自然，敬语得体，无中式英语，语言基本功扎实，词汇丰富。
这就要求我们在谴词造句方面下工夫。
“润色句子包括词语的选择与句型的运用。
”比如可以用高级词汇，短语和固定搭配来替换一般词汇。
增加习惯表达句式，倒装句，it当形式主语和形式宾语，非谓语动词等，使用多种句式，使其多样化。
1: It is necessary for me to listen to the teachers carefully in the class so that I can understand what the teachers say. (把第一句换成it当形式主语的用法，使句式多样化。
)2: I take homework seriously and finish it in time, which is a piece of cake for me.(增加了take…seriously和in time两个短语，是句子更加生动)3: In order to strengthen my body, I often take part in different kinds of exercises with my classmates, such as playing footall, going swimming and playing badminton etc.（增加了in order to do sth目的状语和different kinds of使句子的意思更完整。
）4: Interested in reading books, I develop the habitof going to the library and do some reading on my favourite books.（使用过去分词短语当状语，再添加短语develop the habbit of …使文章增加亮点）步骤五：连句成篇“过渡词在文章中起着承上启下的作用，它好比一座桥梁，能将全文各句有机地联系在一起，从而使句子不再是孤立的独立的个体。
”使用表示转折，并列，递进，因果关系等连词把句子连接起来，“有效地使用了语句间的连接成分，使全文结构紧凑”使上下文更加通顺，逻辑性更强。
I’m a high school student and I understand what I’m studying for. I have been working hard.（原文已给）First of all(过渡词), it is necessary for me to listen to the teachers carefully in the class so that I can understand what the teachers say. What’s more(过渡词), I take homework seriously and finish it in time, which is a piece of cake for me. In addition(过渡词),In order to strengthen my body, I often take part in different kinds of exercises with my classmates, such as playing footall, going swimming andplaying badminton etc. Finally(过渡词), Interested in reading books, I develop the habit of going to the library and do some reading on my favourite books.May there always be colorful life around my school.（原文已给）这篇习作要点齐全，字数符合要求，措辞精美，句式多样化，上下文连贯，符合逻辑和英语表达习惯。
因此在写作中，我们可以适当地使用扩句法对学生进行写作训练，提高学生的英语表达能力。
