一、開頭句型

我們常說，良好的開端等于成功的一半。做事如此，作文也是如此。所以我們頗有必要在作文的開頭花一番心思。

在寫議論文時，你通常以什么樣的方式開頭呢？最簡單也最常用的可能就是開門見山法。也就是說———直截了當地提出你對這個問題的觀點，點出文章的中心思想。

I．．．．has both advantages and

disadvantages．……既有利又有弊。例如：

1．Obviously television has both advantages and disadvantages．

2．Living in a city has both advantages and disadvantages．

3．Com pared with cars，bikes have their advantages and disadvantages．

舉一反三：

1．Although computers bring people a lot of convenience，they have many

disadvantages．

2．．．．has many advantages．For example，．．．However，just as every

coin has two sides，．．．has its

disadvantages．（本例將利弊分開講，轉折過渡自然。just as every coin has two sides也很值得背誦。）
