　　[重复2015-12-05真题]

　　阅读主要观点提取

　　总论点：研究表明高浓度的铅导致了远征北极的海军中毒而死亡。一些人认为是他们食用了含铅的罐装食品。然而，作者对着一观点进行了反驳。

　　理由一：并没有大量的铅进入到食物中。在19世纪，人们用融化的铅来密封食品罐。人们是从罐的外部来密封盖子的，所以，铅接触罐内食物的可能性是非常小的。

　　理由二：没有出现其他同样的案例。许多其他的英国船队也使用铅来密封罐装食品。但是，他们都没有铅中毒的情况。

　　理由三：可能是水手们和了含铅的水。富兰克林的船只都有一套特殊的净水系统，来过滤出可以喝的淡水。然而，净水系统的水管是用铅制成的。

　　听力主要观点提取

　　总论点：探险队员铅中毒的源头就是罐装食品。

　　解释一：成产罐装食品的工人们以一种非常草率的方式来密封盖子。事实上，工人们并没有足够的时间去生产罐装食品。因为时间紧急的原因，工人们在密封的时候并不是非常细心，导致了铅本没有在盖子的外面，而是流进了罐内的食物里。

　　解释二：之所以没有任何关于其他英国船队铅中毒的报道，是因为他们没有检查自己是否铅中毒。没有经过专业的检查，铅中毒是很难被发现的。轻度铅中毒的症状包含疲劳和头疼，但这两点是很常见的，所以很多人会忽视这些症状。

　　解释三：用净水系统净化出来的淡水是供引擎使用的，而不是给水手们饮用的。船上的引擎是蒸汽引擎，因此必须要使用淡水。同时，在船上，他们有另外的饮用水供应。

　　INTEGRATED 综合写作

　　船员中毒的几个解释

　　阅读文章观点：

　　1. 不太可能是罐头内的食物被污染，因为只会污染罐头外部

　　2. 没有报道说其他地方的船员也中毒

　　3. 可能的解释是饮用水被污染

　　听力反驳：

　　1. Time pressures使得workers careless，所以还是有可能的

　　2. 没有报道并不能说明没有发生，可能是中毒症状太common，难以detect

　　3. 水是用于机器的，船员不喝，他们有自己的饮水系统

　　新托福写作题目回忆版本四：

　　阅读：whether the canned food is the factor that contributes to the lead poisoning and the death of crew in Ka a ship.

　　The lead that was carefully stilled to the can would not contact the food.

　　No other evidence of death of the crew was found in other ship.

　　Water purification system may be the source of poisoning.

　　听力：

　　Company has limited time to finish this work. Workers are under time pressure and it is reasonable that they are careless and apply lead to the cans in a hurry way.

　　Sailors may be affected but they are not reported. First, it is difficult to judge whether sailors are affected by lead without careful tests. Second, the symptoms of lead poisoning are common, such as feeling tired or headache and they can be easily overlooked.

　　The water in the purification system is used for ship engineering since the salt water cannot be used. The water for cooking and drinking comes from a different way.

　　新托福综合写作范文:

　　The reading states that the lead in canned food cause the crew poisoning. On the contrary, the professor thinks that the arguments in reading aren’t convincing.

　　Firstly, the author mentions that lead didn’t get into food because melted lead was carefully applied to cans from the outside to seal the lids in place. However, the speaker says that the cans on ships show the melted lead didn't stay on the outside as it was supposed to. In fact, the workers in food company didn’t have enough time to seal the lids carefully. So, the melted lead ran down the inside of the cans, contaminating the food.

　　Additionally, the writer demonstrates that there are no other cases about lead poisoning reported. As a matter of fact, the speaker indicates that sailors on the other ships didn’t test for lead poisoning but lead poisoning is difficult to detect without specific tests. The reason is symptoms of mild lead poisoning include tiredness and headaches, which are very common. Therefore, other sailors might overlook the signs and couldn’t recognize the problems.

　　Finally, the speaker contradicts the idea in reading by suggesting that the main purpose of the water purification systems was to provide freshwater for the ships engines instead of drinking or cooking. It is because those engines were steam engines and they must use freshwater. Moreover, there are separate supplies of freshwater on board for drinking and cooking.
