提升argument3.5分题目牛奶制品。
Argument40.
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.
思路解析：
1.为了评估论证过程，我们需要的第一个证据是在研究过程中，是不是骨质疏松导致了骨折。然而很有可能是因为别的原因，例如说年纪大了，生活方式导致。
2.为了评估论证过程，我们需要的第二个证据是牛奶导致了骨质疏松症，可能是因为环境或者是遗传因素。
3.为了评估论证过程，我们需要的第三个证据是这个研究的具体过程和调查对象。

提升argument3.5分题目骑车与头盔。
Argument41.
The following appeared in a health newsletter.
"A ten-year nationwide study of the effectiveness of wearing a helmet while bicycling indicates that ten years ago, approximately 35 percent of all bicyclists reported wearing helmets, whereas today that number is nearly 80 percent. Another study, however, suggests that during the same ten-year period, the number of bicycle-related accidents has increased 200 percent. These results demonstrate that bicyclists feel safer because they are wearing helmets, and they take more risks as a result. Thus, to reduce the number of serious injuries from bicycle accidents, the government should concentrate more on educating people about bicycle safety and less on encouraging or requiring bicyclists to wear helmets."
思路解析：
1.得出结论基于第一个assumption是study的真实可靠的，然而调查的时间，范围，样本数量和特征，我们都可以取质疑;
2.建议不要戴头盔基于第二个assumption是戴头盔后自行车车祸增加了200%，所以我们可能说不带头盔车祸数量或更多，并且带来头盔车祸率上升了，但是车祸严重度下降了;
3.建议不要戴头盔基于第三个assumption是人们嗲了头盔所以感觉更安全，所以更愿意冒险，所以车祸率上升，然后可能不是因为这个原因，而是因为现在的道路车辆增多，或者说交通设施如红路灯缺少造成的;
4.作者暗示了出事故的人都是戴头盔的，但是可能会因为没有戴头盔而出事故的，如果是这样的话作者的建议就是糟糕的了。

提升argument3.5分题目沙滩侵蚀。
Argument42.
The following is a letter to the head of the tourism bureau on the island of Tria. "Erosion of beach sand along the shores of Tria Island is a serious threat to our island and our tourist industry. In order to stop the erosion, we should charge people for using the beaches. Although this solution may annoy a few tourists in the short term, it will raise money for replenishing the sand. Replenishing the sand, as was done to protect buildings on the nearby island of Batia, will help protect buildings along our shores, thereby reducing these buildings' risk of additional damage from severe storms. And since beaches and buildings in the area will be preserved, Tria's tourist industry will improve over the long term."
思路解析：
1.为了评估论证过程，我们需要的第一个证据是向来沙滩的游客收费，是否可以为填充沙子储备足够的额资金，然后坑内这里收费以后就没有人来了;
2.为了评估论证过程，我们需要的第二个证据是T岛和B岛是否情况一样，很有可能B岛较小，所以不用收取很高的费用就能有足够的资金来填充沙子，然而T岛可能比较大，所以要收取很高的且很长久的费用。
3.为了评估论证过程，我们需要的第三个证据是T岛和建筑保护好了就有利于旅游业的长期发展，然而也很有可能这里的旅游业本身资源不好，而且单个的旅游景点也很难形成集群效应。
