23 背景：The plastic rings that hold six-packs of beverage cans together pose a threat to wild animals, which often become entangled in the discarded rings and suffocate as a result. 条件：All beverage companies will soon use only those rings consisting of a new plastic that disintegrates after only three day’s exposure to sunlight 结论：Once we all complete the switchover from the old to the new plastic rings, the threat will be eliminated 推测：经过三天太阳暴晒会disintegrate，这个要注意 选E，即使降解了，却被水生物吸收，还是对生物有害处
24 背景：Tiger sharks attack tourists swimming and surfing at Tenare’s beaches. 条件：Tourism industry is second to its fishing industry in annual revenue 结论：Kill some tiger sharks 推测：没有虎鲨的存在还会有游客吗？或者对fishing有没有影响？ 选D，小鲨鱼吃鱼，虎鲨吃小鲨鱼，这样fishing industry才有保障

25 背景：As parts of the major renovations to Flowertown’s Main Street train station, consultant proposes a plan 条件：moving the entrance and rent to the retail store 结论：easily pay for those and all other proposed renovations without negative impact on its tight budget 推测：入口的更改不会影响乘客的乘坐次数 选B，入口的改变不会让乘客减少搭乘的次数，那么就没有影响到火车站的收入
26 背景： 条件：PZ1000 has the fewest injuries per accident of any car in its class 结论：PZ1000 is one of the safest cars available today 推测：对比的是什么？或者别的车还没有accident？ 选C，PZ1000的车会发生车祸的几率更大，不能说是safest
今天第一题就卡住了，不过看完解释后豁然开朗啦~~~因为conclusion里没说是new还是old plastic~~~ 所以选B~~~刚开始不确定是不是B就是因为没注意到这一点，脑海里一直都是the new plastic\ sunlight~~~连prephrase都偏啦~~~ 不过还好后面的题做对了，虽然分析的比较慢~~~ -------------------------------------------- 1. Time: 01:05 BG: the plastic rings of beverage cans pose a threat to wild animals by suffocating them. Premise: All beverage companies will soon use new plastic rings that disintegrate after 3 days exposure to sunlight. Conclusion: once we all use the new plastic, the threat to wild animals will be eliminated. Type: weaken Prephrase: where the new plastic deposits has no sunlight. Choice: B (A)The switchover to the new plastic rings willtake at least two more years to complete. ---------- no matter how long it takes to complete, the conclusion may still be established once completed.(B) After the beverage companies have switchedover to the new plastic rings, a substantialnumber of the old plastic rings will persistin most aquatic and woodland environments. ---------- correct. the representative does not say the threat from new plastic rings will be eliminated, but rather the threat from plastic rings, which includes both old and new rings. (C) The new plastic rings are slightly lessexpensive than the old rings. ---------- the price of the plastic has nothing to do with the elimination of the threat. Out-of-scope answer.(D) The new plastic rings rarely disintegrateduring shipping of beverage six-packsbecause most trucks that transport cannedbeverages protect their cargo from sunlight. ---------- this answer does not affect the conclusion because it does not address the threat of suffocation to animals.(E) The new plastic rings disintegrate intosubstances that are harmful to aquaticanimals when ingested in substantialquantities by them. ---------- this choice neglect the specific of the threat stated in the conclusion, i.e. the threat of suffocation. Shell Game
Remember, one of the rules for weakening arguments is to focus on the conclusion, and knowing the details of the conclusion is part of that focus.Never choose answer choice (E) just because the first four answers are not overly attractive! Always make a thorough analysis of every answer choice and remember that the test makers know that people get nervous if none of the first four answer choices jump out at them. Do not let the test takers draw you into a trap!

前提：plastic rings will give threat to wild animals A new kind of plastic rings will not give this kind of threat to wild animals because of 这种东东的自我分解 结论：therefore, this new plastic rings will reduce the threat to the wild animals Predicated answers: 在分解的几天当中仍然对wild animals 造成了危险，所以没有减少这种危险 A 花两年的时间来完成，并没有说明有效还是没有效，这个answer是无关的。 B 削弱？因为即使这个有作用，但是有大量的old的残存，导致新的增加，旧的没有消除，所以不可能减少 C 无关，这里没有说贵不贵的事情 D 跟在运输的过程中也没有关系，无关 E 偷换概念，题目中说的是the threat to the wild animals, 跟消不消化之间有害没害的并没有提及。
