A. 高中英語寫作常用的句型
一篇文章通常可分為三個部分，即開頭、正文和結尾。這三個部分安排是否得體，直接影響到文章的質量。
文章的開頭一般來說應盡量做到開門見山，用簡單明白的敘述引出文章的話題，使讀者了解文章要談論什麼，一下於引起讀者的興趣。
作文常見的開頭形式大致有以下幾種：
1.開門見山，揭示主題
文章一開頭，，就交待清楚文章的主題是什麼。如「How I Spent My Vacation」(我怎樣度假)的開頭可以寫成：
I Spent my last vacation happily．
"Honesty"(談誠實)的開頭可以寫成：
Honesty is one of the best virtues．An honest man is always trusted and respected．On the contrary, one who tells lies is regarded as a "liar"，and is looked upon by honest people．
2.交代人物、事情、時間或環境開頭
在文章的開頭，先把人物、事件和環境交待清楚。例如"A Trip to Jinshan" (去金山旅遊)的開頭可以寫成：
The day before yesterday my class went on a bus trip to Jinshan. The bus ride there took three hours. The long trip made us very tired, but the sight of the beautiful sea refreshed us.
3. 回憶性的開頭
用回憶的方法來開頭。例如"A Trip to the Taishan Mountain"(泰山游)的開頭是：
I remember my first trip to the Taishan Mountain as if it were yesterday.
4.概括性的開頭
即對要在文章中敘述的人或事先作一個概括性的介紹。如「The Happiness of Reading Books」(讀書的快樂)的開頭：
People often say that gold and silver are the most valuable things in the world. But I say that to read books is more valuable than anything else, because books give us knowledge and knowledge gives us power.
5.介紹環境式的開頭
即開頭利用自然景物或自然環境引出要介紹的事物。如「An Accident」(一場事故)的開頭可以寫成:
It was a rainy and windy morning. The sky was gloomy, the temperature was low, and the street was nearly empty. I was on my way back to school. Suddenly, a speeding car came round the corner.
6.交待寫作目的的開頭
在文章的一開頭就交待寫作目的，如通過文章要表揚誰，批評誰，或說明一個什麼問題等。如 "Pollution Control" (控制污染)的開頭：
In this article I shall draw your attention to the subject of pollution control.
1.結尾萬能公式一：如此結論
說完了，畢竟要歸納一番，相信各位都有這樣的經歷，領導長篇大論，到最後終於冒出個「總而言之」之類的話，我們馬上停止開小差，等待領導說結束語。也就是說，開頭很好，也必然要有一個精彩的結尾，讓讀者眼前一亮，這樣，你就可以拿高分了！比如下面的例子： obviously（此為過渡短語）， we can draw the conclusion that good manners arise from politeness and respect for others. 如果讀者很難「顯而見之」，但說無妨，就當讀者的眼光太淺罷了！
更多過渡短語： to sum up， in conclusion， in brief， on account of this， thus
更多句型： thus， it can be concluded that……， therefore， we can find that…
2.結尾萬能公式二：如此建議
如果說「如此結論」是結尾最沒用的廢話，那麼「如此建議」應該是最有價值的廢話了，因為這里雖然也是廢話，但是卻用了一個很經典的虛擬語氣的句型。 obviously， it is high time that we took some measures to solve the problem. 這里的虛擬語氣用得很經典，因為考官本來經常考這個句型，而如果我們自己寫出來，你說考官會怎麼想呢？
更多句型： accordingly， i recommend that some measures be taken. consequently， to solve the problem， some measures should be taken.
