題目

Milk and dairy products are rich in vitamin D and calcium—substances essential for building and maintaining bones. Many people therefore say that a diet rich in dairy products can help prevent osteoporosis, a disease that is linked to both environmental and genetic factors and that causes the bones to weaken significantly with age. But a long-term study of a large number of people found that those who consistently consumed dairy products throughout the years of the study have a higher rate of bone fractures than any other participants in the study. Since bone fractures are symptomatic of osteoporosis, this study result shows that a diet rich in dairy products may actually increase, rather than decrease, the risk of osteoporosis.

Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

題目翻譯

牛奶和奶製品富含維生素D和鈣，這些都是骨骼生長和保持骨骼健康所必須的物質。因此很多人相信多吃奶製品的飲食可以有助預防骨質疏鬆症 [譯]骨質疏鬆症與環境因素和基因因素都有關係，而且它導致骨骼隨年齡增長而脆性顯著增加。但是對大量人羣的進行的一項長期研究發現：那些在研究期間經常食用奶製品的人骨折發病率比其他參加研究的人要高。由於骨折是骨質疏鬆症的症狀之一，這一研究結果表明多吃奶製品實際上會增加而不是減少患骨質疏鬆症的風險。

説明：寫一篇文章，闡述需要哪些具體的證據來評價這個論證過程，並解釋這些證據如何削弱或強化這個論證過程。

提綱(可攻擊點)

1、“維生素D和鈣”是骨骼生長和保持骨骼健康所必須的物質，但是食用“牛奶和奶製品”是否就會給人體補充充足的骨骼生長和保持骨骼健康所必須的物質?

2、“骨折是骨質疏鬆症的症狀之一”，但能否僅根據骨折就説明骨質疏鬆?

3、食用奶製品僅僅是保證“骨骼生長和保持骨骼健康”的一個因素，和“與環境因素和基因因素都有關係有關”而且“是一種骨骼隨年齡增長而脆性顯著增加的疾病”的骨質疏鬆相比，是否存在直接對應關係?
