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

牛奶和奶制品富含維生素D和鈣,這些都是骨骼生長和保持骨骼健康所必須的物質(zhì)。因此很多人相信多吃奶制品的飲食可以有助預防骨質(zhì)疏松癥 [譯]骨質(zhì)疏松癥與環(huán)境因素和基因因素都有關(guān)系,而且它導致骨骼隨年齡增長而脆性顯著增加。但是對大量人群的進行的一項長期研究發(fā)現(xiàn):那些在研究期間經(jīng)常食用奶制品的人骨折發(fā)病率比其他參加研究的人要高。由于骨折是骨質(zhì)疏松癥的癥狀之一,這一研究結(jié)果表明多吃奶制品實際上會增加而不是減少患骨質(zhì)疏松癥的風險。

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

題目分析

A. 前提:bone fractures are a symptom of osteoporosis

骨折是骨質(zhì)疏松癥的癥狀之一

B. 結(jié)論:a diet rich in dairy products may actually increase, rather than decrease, the risk of osteoporosis

多吃奶制品實際上會增加而不是減少患骨質(zhì)疏松癥的風險

C. 論據(jù):

1. Milk and dairy products are rich in vitamin D and calcium, substances essential for building and maintaining bones

牛奶和奶制品富含維生素D和鈣,這些都是骨骼生長和保持骨骼健康所必須的物質(zhì)

2. Many people therefore believe that a diet rich in dairy products can help prevent osteoporosis, a disease in which the bones weaken significantly with age and that is linked to both environmental and genetic factors

很多人相信多吃奶制品的飲食可以有助預防骨質(zhì)疏松癥

3. Osteoporosis is a disease in which the bones weaken significantly with age and that is linked to both environmental and genetic factors

骨質(zhì)疏松癥是一種骨骼隨年齡增長而脆性顯著增加的疾病,而且它與環(huán)境因素和基因因素都有關(guān)系

4. A long-term study of a large number of people found that those who have consistently consumed dairy products throughout the years of the study have a higher rate of bone fractures than any other participants in the study

對大量人群的進行的一項長期研究發(fā)現(xiàn):那些在研究期間經(jīng)常食用奶制品的人骨折發(fā)病率比其他參加研究的人要高

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(zhì),但是食用“牛奶和奶制品”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(zhì)?

2、“骨折是骨質(zhì)疏松癥的癥狀之一”,但能否僅根據(jù)骨折就說明骨質(zhì)疏松?

3、食用奶制品僅僅是保證“骨骼生長和保持骨骼健康”的一個因素,和“與環(huán)境因素和基因因素都有關(guān)系有關(guān)”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(zhì)疏松相比,是否存在直接對應關(guān)系?
