About 30% to 40% of American adults have a condition that has no visible signs and rarely causes symptoms, but can raise the risk of heart disease, diabetes, cirrhosis and liver cancer. It’s called nonalcoholic fatty liver disease. And as American waistlines continue to expand, the prevalence of this dangerous condition is growing as well. Nonalcoholic fatty liver disease, or NAFLD, is an umbrella term. Most people with NAFLD have what’s known as simple fatty liver, which means that more than 5% of the liver is made up of fat cells. (Fat in the liver can also be a product of heavy alcohol use, which is known as alcoholic fatty liver disease.) Like fat accumulation in the rest of the body, this condition is often related to obesity, poor diet and sedentary lifestyle. Excess weight also seems to make genetic risk factors worse. A recent study published in Nature Genetics found that people with a high-risk variant of the PNPLA3 gene were much more likely to have fatty liver disease if they were obese than if they were thin. People with simple fatty liver don’t have inflammation or scarring in their liver and don’t appear to be at high risk for liver complications. But the condition affects insulin sensitivity and puts people at higher risk for diabetes and cardiovascular disease.

思路引導 VIP
請你觀察文章中出現的「30% 到 40%」、「NAFLD」的定義，以及對基因研究結果的引述。當一個作者在文章中大量運用數據、專有名詞解釋和科學研究發現，卻沒有使用感性的抒情字眼，也沒有強烈要求讀者去做某件事（例如「你必須購買...」）時，他最主要的目的是希望讀者在讀完後獲得什麼呢？

恭喜你精準地判斷出這篇文章的核心意圖！這類題目考驗的是對「文本類型」的掌握。這段文字透過具體的數據（如 30% 到 40% 的成年人）、科學定義（非酒精性脂肪肝 NAFLD）以及研究報告，客觀地向讀者介紹一種健康狀況及其成因與風險。
客觀陳述與資訊傳遞
這篇文章的核心在於提供關於醫學知識的背景。作者並非要講故事來娛樂 (entertain) 讀者，也沒有針對某個議題進行反對 (object) 或強制性的說服 (persuade)；雖然文中提到了酒精性與非酒精性的差異，但其本質是為了釐清定義，而非以兩者之間的比較 (compare) 作為主體。這種以事實與數據為導向的寫作風格，正是「告知 (inform)」類文本的典型特徵。
