1 44s 背景：啤酒厂生产啤酒的易拉罐的东东的那个拉环对野生动物造成了伤害。 前提：啤酒长会采用一种新的拉环，这种拉环在太阳下会自动的消失。 结论：使用这种拉环将不会对野生动物造成伤害。 预测答案：就是那3分钟没有消失的拉环将会给野生动物带来危害。 D A 无关，B 无关 C无关 E无关 2 41s 前提：人们来好莱坞是为了看名人的，而且高板凳和高桌子的人会消耗较少的时间在吃饭上。 结论：所以为了增加利润，饭店的老板应该增加高凳子和高桌子。 削弱：增加了高凳子和桌子，人们将不会来这些餐馆了。 A 无关，与名人没有关系 B 无关 C D 无关比较 E 觉得C，Ｅ好像能行，有点不确定。 先选Ｃ试试 ３ ４５Ｓ 背景：英国的谷物长的很好，因为用了除草剂。因为除草剂，英国的一种鸟的数量在下降。 前提：在这种鸟生活的地方，是没有使用除草剂的。 结论：因此，鸟的减少不是因为除草剂，而是由于别的原因造成的。 预测答案：由于某种原因，即使没有使用除草剂的地方，也有除草剂的出现。 Ａ ４ ２５Ｓ 前提：S航空公司比Ａ航空公司在事故等２个方面的危险程度更高。 结论：所以在选择神马路线的时候选择Ａ不选择Ｓ，多出一点钱也是值得的。 预测答案：Ｓ走的都是出事故较多的地方，相对而言S事故的发生率是安全的，而A走的是本来就安全的地方。 A 无关 B C 无关 D 无关 Ｅ支持 ５ 前提：在海岸线附近钻油，会有漏油的危险，但是用油轮运输的话，也有危险，而且危险更大。 结论：所以减少在海岸线钻油的危险，减少油轮的运输。 预测答案： 这种方法的难度太大 A B重复前提 C支持 D 无关 E 无关 6 31s 背景：现在进口钢铁不能帮助美国大的钢铁厂 结论：帮助了小的钢铁厂 预测答案：不能帮助小的钢铁厂 Ｅ
1. Background：plastic ring pose a threat to environment Premise: complete the switchover from sunlight Conclusion: threat will be eliminate. 选B after switchover, still threat environment，达不到减少破坏环境的目的。
2. Background: 目前HR只有一个standard-height table Premise: 顾客喜欢tall table with stool, 并且顾客坐stools吃饭比standard-height table快 Conclusion: 如果配置多的high table and stools, 利润会增加 选D 吃饭快不等于消费多，达不到利润增加的目的
3. 前提：除草剂让谷物长得快 除草剂的使用导致谷物周围鸟的减少和中毒，但tests show no trace Conclusion: 不是除草剂导致P减少 选A 除草剂导致P常吃的虫子减少，于是导致P减少。削弱。
4. 背景： SA比AD评级差 因此：虽然AD贵，但选它flight from P to D，更安全 选C P to D 的航路，SA的飞机比AD好
5. 前提：importing oil on tankers比Offshore oil-drilling operations漏油风险大 结论：invest more in offshore operations and import less oil on tankers 选A (我第一反应也是选D 哈哈)
6. 限制进口配额不能帮助美国大钢铁厂 但能帮助美国小钢铁厂 E 这题的逻辑链我找不出来….. T T 新人压力大啊 T T
1. 1) 45s 2) Premise 1: Old rings for 6 cans of beverage pose threat to wild animal by suffocating them. Premise 2: New ring, which will disintegrate only in 3 days after discard in wild, will be used by all beverage producers. Conclusion: Once it is implemented, the threat to suffocating animals will be removed. 3) Change to new ring only means to ensure no additional old rings will be thrown to wild. Existing old rings are still out there, threatening wild animals. 4) B 5)ACDE irrelevant
2. 1) 36s 2) Premise 1: Now Hollywood use only standard-height seats. Premise 2: Customers prefer high seats and stools to better see celebrities. Premise 3: Customers stay shorter than on high seats.

3. 1) 39s 2) Background: Herbicides make crops grow more efficiently by eliminating crops’ competitors. Premise 1: In somewhere, population of P birds around crop field decreases. Premise 2: Someone believed it is herbicides that killed birds Premise 3: No more than trace quantity of herbicides are found inside P birds’ body. Conclusion: Something else, rather than herbicides, makes P birds population decrease. 3) Trace of quantity does not mean it cannot kill P birds. 4) E 5)A support BC irrelevant D insufficient
4. 1) 25s 2) Premise 1: Air D performs better than Air S in terms of both accident frequency and accident severity. Premise 2: Air D is more expensive. Premise 3: It is worth to take a safer flight by paying more Conclusion: One should choose Air D from Point A to B. 3) Premise 1 is general condition. Air D could have worse records than Air S from A to B. 4) B 5)ACD irrelevant E insufficient
5. 1) 2) Premise 1: Offshore oil drilling has an unavoidable risk on oil spill. Premise 2: Oil import in tanker has a bigger such risk. Premise 3: We want to reduce such risk without curtailing oil usage Conclusion: We should do more 1 instead of 2 3) There can be other ways of obtaining oil with less such risk 4) A 5)BC support DE irrelevant
6. 1) 2) Premise 1: The importing limited quotas are in fact helping US small steel producers Premise 2: Small steel producers, rather than foreign ones, seize business from big steel producers under such quota. Conclusion: Importing quotas is not effective in helping US big steel producers 3) Seize by small from big happens with/without quota. The quota limited competition against big ones from foreign ones 4) B 5)AC irrelevant DE support
1 1) 计时： 2) 逻辑链： Background Information: The plastic rings that hold six-packs of beverage cans together pose a threat to wild animals Premise: switchover from the old to the new plastic rings Conclusion: the threat will be eliminated. 3) 推测：在太阳下三分钟会消失的拉环，还是会危害动物 4) 选项分析：选E A,B与新拉环是否有保护动物的作用无关；C拉环的成本与动物保护无关；D新拉环在运输过程中是否会分解，与威胁动物无关；E 新拉环不会使动物们entangled in the discarded rings，但是分解物会危害动物，最终还是不能解决拉环危害动物的问题。
2 1) 计时： 2) 逻辑链： Background Information: Hollywood Restaurant has only standard-height tables. Premise: many customers would prefer tall tables with stools； diners seated on stools typically do not stay as long Conclusion: 改为all tables with stools后，利润会增长。 3) 推测：改后利润不变或降低 4) 选项分析：选D AC赞同两个前提：喜欢高桌子；不会在高桌子上待很久。 B 如果占用桌子时间过长，会收费，所以高桌子、标准桌子，虽会影响客人占用时间，但不会增加或降低商家利益。 E 和Hollywood Restaurant的利益无关。 D坐的时间短的人，点菜也会便宜些。高桌子坐的时间短，点的菜会便宜些，减少商家收入，所以高桌子不好。
3 1) 计时： 2) 逻辑链： Background Information: partridge populations have been steadily decreasing since herbicide use became widespread.

artridge：用除草剂、产量少、周围鸟没有死
鸟的数量减少是其他的原因
