同學們好!你們現在一定都在忙於的四,六級考試,根據平時作文批改及同學們的反饋,作文一直是同學們的弱項,這裡給同學們談談作文段落的基本寫作方法,希望能給同學們一點啟發和幫助.
通常段落由二至三部分組成,即主題句，擴充套件句 和結尾句組成，主題句擴充套件句和結尾句 四六級作文好點子。主題句是段落的'核心，它表明作者的觀點和態度，同時反映段落的中心思想。主題句的特點是：一是具有明確的觀點；二是具有一定的概括性。記住段落的中心思想應該是一個，要清楚地把它表達出來，儘量不要出現語言錯誤。
如： Advertisement is an important link between producers and consumers today./The library supplies people with knowledge of all kinds./Nowadays ,the computer has found wide applications in many fields.
以上句子都具備了主題句的特點，因為所有這些句子都可以用其它句子來解釋，描述，分析等即擴充套件句———主要圍繞主題句進行敘述，大學英語《主題句擴充套件句和結尾句 四六級作文好點子》。說明或論述，它是主題句發展成短落的主要組成部分。請看下面的段落：

There are many problems with advertisements times ,people consider them as a bad thing because many of the goods sound advertisements are rather confusing ,and often deceive consumers into buying goods of poor solutions to these problems is that a necessary law should be worked out rwise some advertisements will be harmful to the society. 該段的結尾句是：The solution ----harmful to the society.
最後一句說出瞭解決的方式及不加以解決會產生的不良後果。但要注意的是段落結尾句需要簡明扼要，並符合主題句的主旨，不過不能簡單的重複。以上是段落的基本寫作套路和方法，請同學們根據上述方法將下列主題句擴寫成60字左右的段落：
