句子結構是雅思寫作評分標準“語法的多樣性與準確度”中一項十分重要的考量因素，但這并不意味著要求考生具備寫長難句的能力。在追求輸出像雅思閱讀一樣精到的語言之前，我們首先要確保的應當是寫出來的句子是正確的。有效的句子甚而段落通常應當同時滿足以下五個要素：一致、連貫、簡潔、強調、多樣。

　　1. 一致：如句內的邏輯關系，注意檢查是否存在簡單推論、邏輯殘缺、邏輯悖論、依賴偏見等。

　　Born in a small town in South Chinain the early 1950s, he grew up to be a famous musician。

　　→ He was born in a small town in South China in the early 1950s. In his childhood he liked to sing songs. Later he entered a conservatory. In the 1970s he became a famous musician。

　　2. 連貫：這個問題在平行結構、共用主語、使用指代的情況下尤其需要注意。

　　We thought she was charming, intelligent, and a very capable young woman。

　　→ We thought she was charming, intelligent, and very capable。

　　Or: We thought she was a charming, intelligent, and very capable young woman。

　　He was knocked down by a bicycle, but it was not serious。

　　→ He was knocked down by a bicycle, but was not badly injured。

　　Looking out of the window, the grassland stretches as far as the eye can reach。

　　→ Looking out of the window, we can see the grassland stretching as far as the eye can reach。

　　He gave a reason for not attending the meeting, which nobody believed。

　　→ He gave a reason, which nobody believed, for not attending the meeting。

　　Or: He gave a reason for not attending the meeting, a reason which nobody believed。

　　3. 簡潔：英美文化推崇坦率和直接，通常不需要體現咱儒家文化的含蓄和委婉。

　　It was small in size and blue in colour。

　　→ It was small and blue。

　　He usually likes to drink all kinds of wines that are produced in France。

　　→ He prefers French wines。

　　4. 強調：正如每篇文章都要有中心思想(main idea)，每個段落都要有主題句(topic sentence)一般，每個句子都要圍繞一個中心觀點清晰地呈現出作者想要表現的重點。

　　He is modest and hardworking and is a good student。

　　→ He is a good student, modest and hardworking。

　　There is a big tree, which is said to be 300 years old, in the temple。

　　→ In the temple there is a big tree, which is said to be 300 years old。

　　At the sight of the disorderly crowd, he was aware that something bad would be possible。

　　→ The moment he saw the disorderly crowd, he knew that something bad would happen。

　　5. 多樣：中文重重復，英文重替代，中英差異使然。
