高三英語作文寫作技巧
追加成分，擴展句子
在閱讀理解中遇到長句子時，我們要學會通過找句子主幹，把長句子縮短;而在寫作文時，我們則要反其道而行，針對目標句子，我們在要點基礎上適當添加合乎邏輯的附加成分，如定語(從句)、狀語(從句)、非謂語結構、獨立主格等成分，使表達更清晰，主題更突出。
例1高考臨近，學習時間變緊，任務加重，很多同學內心壓力大，學習效率低下。請爲即將舉行的班會寫一篇英語演講稿，談談你對保持良好的精神狀態，高效而健康地進行復習備考的建議。要點如下：堅持鍛鍊;合理計劃;注重飲食。
要點拓展如下：
1.堅持鍛鍊
普通表達：We should keep on doing exercise.
高級表達：To keep up good spirits and prepare for the big day efficiently and healthily，we are advised to do regular workout，building up our bodies.
2.合理計劃
普通表達：We should have proper study plan.
高級表達：Never hesitate to make an organized and proper schedule，which contributes much to the accomplishment of our academic assignments.
3.注重飲食
普通表達：we should pay special attention to our diet as well.
高級表達：Certainly，keeping a balanced diet，we are bound to feel energetic and dynamic，which serves the most essential functions.
點評：在對所給要點進行簡要分析之後，就應考慮使用哪些詞語和句式，從而符合五檔作文所要求的“有高級詞彙和高級句式”的標準。在以上三個要點的處理上，通過添加高級詞彙如efficiently and healthily，regular workout，organized and proper schedule，academic assignments，feel energetic and dynamic，essential以及分詞結構、定語從句等成分，充分擴充了句子，不僅篇幅更長，亮點也更多了。
補加語句，充實文章
根據作文的行文走向，適當增加一些與主題相關的語句，或根據作文題目中提示的要點，恰如其分地衍生出一些句子，即能夠起到“前引後聯”的作用，又可以補充一些相關信息，幫助讀者理解所寫內容。此外，還可以起到協調句式，避免單調的作用。
例2假定你是李華，你的朋友湯姆得知中國學生數學成績總體優於英國學生，所以他想知道中國數學教與學的情況，請你寫一封郵件回覆他。要點如下：課堂學習時間;作業量;課外學習等。
要點拓展如下：
1.課堂學習時間
A special Chinese high school student usually has seven math classes per week，and some schools even offer nine classes for math，in which teachers often address key points and most common problems they’ve found in students’ homework handed in recently.
2.作業量
Due to teachers’ immediately feedback on their homework，the majority of the students are able to have a good command of their learning materials，even though the workload is quite huge.
3.課外學習
Besides homework，some students also manage to spend extra time reviewing what they’ve learned in class and get their notes organized. The revision style varies，but there is a common belief among students that math is of great importance. As a result，they devote quantities of time to it.
點評：該作文題所給提示並不多。在完成該作文前，同學們要考慮以下幾個問題：1.課堂學習時間是多還是少?每週有多少節課?2.作業量是大還是小?每天有多少?3.課外學生都有哪些課外活動來學習數學?
通過有針對性地對目標進行分析，我們要爲自己的作文找到拓展的方向。
此外，我們還可以根據實際情況添加一兩句名言警句來點綴文章，使評分再上一個檔次。
例3 Were I three years younger than I am now，I would strongly recommend that I set more practical and specific goals. As an old saying goes，living without a clear and achievable aim is like sailing without a compass. Compared with many abstract objectives，practical ones can bring us more courage and confidence whenever we make one step forward.
點評：Living without a clear and achievable aim is like sailing without a compass.這個句子儘管結構並不複雜，屬於“主—系—表”結構，但該句採用了類比這一修辭手法，將無目標的生活比作無指南針的航海，頓時使人生目標形象起來。
添加過渡，條理清晰
在寫作當中，恰當使用一些銜接手段，包括使用過渡詞和過渡句，可以使文章嚴謹、流暢、富有節奏。
例4假定你是李華，你校攝影俱樂部(photography club)將舉辦國際中學攝影展。請給你的英國朋友Peter寫封信，請他提供作品。信的內容包括：
1.主題：環境保護;
2.展覽時間;
3.投稿郵箱：。
注意：
1.詞數100左右;
2.可以適當增加細節，以使行文連貫。
Dear Peter，
Our school photography club is going to hold an International High School student Photography Show. As far as I know，the theme of the show is environmental protection. Actually，I know you are gifted in taking good pictures and have always wanted to do something for environmental protection. I clearly remember you showed me some photos on that theme the last time you visited our school. In addition，it will start from June 15th and last three weeks and what makes us excited is that any student who is interested can participate in it. In a word，I firmly believe that this is surely a good chance for more people to see them. If you want to join，please send your photos to .
Hope to hear from you soon.
Yours，
Li Hua
點評：本篇範文很好地完成了要求，要點擴充合情合理。全文句式多樣化，並沒有一直使用陳述句，而是穿插使用祈使句等多種句式，符合邀請函的`特點。文章中使用了較多的複合句，如定語從句any student who is interested can participate in it，時間狀語從句... the last time you visited our school，條件狀語從句If you want to join ...等，體現出不錯的駕馭英語的能力。
此外，本文使用了as far as I know，in addition，in a word，等過渡短語，巧妙地將三個要點“主題、展覽時間、投稿郵箱”串聯起來，使閱卷老師對作者表述的意思一目瞭然，同時也增強了文章的條理。
我們寫作當中經常會用到的過渡語有：first of all，to begin/start with，in the first place，first and foremost，second(ly)，furthermore，moreover，what’s more，in addition，besides，but，however，on the contrary，nonetheless，in contrast/comparison，nevertheless，hence，therefore，in conclusion，to conclude，in a word，last but not least等。
重點突出，詳加描述
在對文章進行展開時，除了可以採用前文提到的添加追加成分、過渡成分來拓展句子外，我們還可以根據題目提示，確定整篇文章的主要點和次要點，在主要點上着力發揮，次要點表述清楚即可，不用過多渲染。
例4讀下面圖畫，按要求用英語寫一篇詞數爲120左右的短文。
內容包括：
描述畫面;
概述其含義;
談談個人感想。
鑿壁偷光
注意：
1.短文開頭已給出，不計入總詞數;
2.可以適當增加細節，以使行文連貫;
3.短文中不能出現與本人相關的信息。
In the picture，we can see a boy in worn clothes，who was reading a book with full attention. He was sitting at a shabby wooden table with a pile of books on it and a weak ray of light came in through a small hole in the wall.
This is a well-known story from an ancient Chinese idiom. The boy，being poor，couldn’t afford even a candle，so he bored a hole in the wall to “steal” light from his neighbor’s house to read at night. The moral of the story is that we should spare no effort to acquire knowledge and never get discouraged easily no matter how difficult the situation may be.
Of course，things are totally different today. It is not the story itself but what is reflected in the story that counts. Hard work pays off. We should take pains to improve ourselves through learning and get prepared for the future.
點評：該篇習作語言豐富，表達準確，結構清晰，過渡自然，尤其在內容的安排和取捨上，處理得十分恰當。本題的三個要點中，要點3是本文的重頭戲，體現了高考作文題的“思想性”，本文對此着重“潑墨”，所佔篇幅幾乎爲全文篇幅一半，要點2次之;針對要點1，本文對圖片僅需作簡要描述，一句話即可。
“不積小流，無以成江河;不積跬步，無以至千里”。要想寫出高質量的考場作文，就需要“適當添加細節”。而細節的增加需要從實際需要出發，結合作文的題材、體裁以及題中給出的要點，“畫龍點睛”式地添加，不要信口開河，更不能夠信馬由繮、亂加一氣，最終偏離主題，給閱卷老師留下“該寫的不寫，不該寫的寫得過多”的不良印象。
