思維導圖的製作，可以使用計算機也可以手繪。計算機制作精美，難度大，需要用到Mind Manager，i Mind Map 等軟件。手繪雖然較粗糙，但繪製方法簡單隨意，更能培養學生動手操作能力。
思維導圖目前已廣泛運用在中小學教育中，在英語閱讀教學中，繁雜且篇幅較長的文章總令學生望而生畏，不易激發起他們的閱讀興趣和學習慾望。而思維導圖基於聯想、無限延伸，把原本枯燥的黑白文字，用色彩斑瀾的可視化圖像來呈現，能夠增強學生的閱讀興趣，還能夠有效促進學生對文章內容和結構的理解，提高學生的英語閱讀能力。
以人教版高中英語必修5 Unit 1 JOHH SHOW DEFEATS “KING CHOLERA”為例，本文介紹英國著名醫生John Snow是如何通過考察、分析、探究的科學方法，發現並控制“霍亂”這種傳染病的。雖然他沒有發現導致霍亂的病原體，但他創造性地使用空間統計學查找到傳染源，並以此證明了這種方法的價值。今天，繪製地圖已成為醫學地理學及傳染病學中一項基本的研究方法。“斯諾的霍亂地圖”（Snow’ Cholera map）成為一個經典案例。這篇文章從詞彙到題材，對學生來說都有一定難度，藉助思維導圖的幫助，極大地提升了學生對文章內容和結構的把握。
原文JOHH SHOW DEFEATS “KING CHOLERA”
John Snow was a famous doctor in London -so expert, indeed, that he attended Queen Victoria as her personal physician. But hebecame inspired when he thought about helping ordinary people exposed tocholera. This was the deadly disease of its day. Neither its cause nor its curewas understood. So many thousands of terrified people died every time there wasan outbreak. John Snow wanted to face the challenge and solve this problem. Heknew that cholera would never be controlled until its cause was found. He became interested in two theories that possibly explained how cholerakilled people. The first suggested that cholera multiplied in the air. A cloudof dangerous gas floated around until it found its victims. The secondsuggested that people absorbed this disease into their bodies with their meals.From the stomach the disease quickly attacked the body and soon the affectedperson died. John Snow suspected that the second theory was correct but he neededevidence. So when another outbreak hit Londonin 1854, he was ready to begin his enquiry. As the disease spread quicklythrough poor neighbourhoods, he began to gather information. In two particularstreets, the cholera outbreak was so severe that more than 500 people died inten days. He was determined to find out why. First he marked on a map the exact places where all the dead people hadlived. This gave him a valuable clue about the cause of the disease. Many ofthe deaths were near the water pump in Broad Street (especially numbers 16, 37,38 and 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street)had had no deaths. He had not foreseen this, so he made further investigations.He discovered that these people worked in the pub at 7 Cambridge Street. They had been givenfree beer and so had not drunk the water from the pump. It seemed that thewater was to blame. Next, John Snow looked into the source of the water for these twostreets. He found that it came from the river polluted by the dirty water from London. He immediatelytold the astonished people in Broad Street to remove the handle from the pump so thatit could not be used. Soon afterwards the disease slowed down. He had shownthat cholera was spread by germs and not in a cloud of gas. In another part of London,he found supporting evidence from two other deaths that were linked to the Broad Streetoutbreak. A woman, who had moved away from Broad Street, liked the water from thepump so much that she had it delivered to her house every day. Both she and herdaughter died of cholera after drinking the water. With this extra evidenceJohn Snow was able to announce with certainty that polluted water carried thevirus. To prevent this from happening again, John Snow suggested that thesource of all the water supplies be examined. The water companies wereinstructed not to expose people to polluted water any more. Finally "KingCholera" was defeated.
