5'11'
C?CBE
where is the boldface?

错了第三题.
1. 1'11
3. 分析：可以用排除法，其他选项很好排除。
C：如果除了带collar之外还有别的原因要用tranquilizer，那么文中的‘Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females ‘ ，说明re 和un的犀牛可能注射的镇静剂量差不多，也就不能说明镇静剂是影响生育的原因。
4.1’30

【精练】

Current pattern must change

Metal availableà renewableresource

Assumption--B

(纠结了N久…Bible解释很给力:Using the AssumptionNegation Technique, the following would clearly attack the conclusion: “We canindefinitely replace exhausted nonrenewable resources with other nonrenewableresources.” If the nonrenewable resources can be indefinitely replaced, why dowe need to change our consumption habits? )

【逻辑链】

1. boldface 呢….

2. wear radio collarsà trackrhinoceroses

Evaluate—E(C)

3.tax increase sales had fallen

Cigarette sales stronglyrelated to after-tax price

Strengthen—B

4.complete the argument--E

精炼 2‘19’‘
premise: there is only so much metal ore available
subconclusion:we must either do without or turn to renewable resources to take its place.
conclusion:The current pattern of human consumption of resources must change
Q:assumption
prephrase: 没有GAP，应该是削弱否定，很可能是否定句
(A) There are renewable resource replacements for
all of the nonrenewable resources currently
being consumed.------irrelevant; 让你判断 either do without，而该选项取非，部分可再生资源已经被消费了不削弱结论
(B) We cannot indefinitely replace exhausted
nonrenewable resources with other
nonrenewable resources.---correct;取非后，非可再生依然可以有其他非可再生代替，那么也就没必要转化模式
(C) A renewable resource cannot be exhausted by
human consumption.------opposite；该选项削弱结论
(D) Consumption of nonrenewable resources will
not continue to increase in the near future.-----取非后，对不可再生资源的消费增加，那么slightly support了结论，但是假设是取非削弱The author does not make statements in the near future;irrelevant?
(E) Ultimately we cannot do without nonrenewable
resources.-----没有理解，答案reads as “Ultimately we must have nonrenewable resources.，实际上削弱了结论，也就是不可用可再生资源代替
感觉这题主要是对we must either do without or turn to renewable resources to take its place.这句话的理解我是这样理解的，我们要么以后什么都做不了要么转向使用可再生能源

逻辑链：
1.53’‘
Most of Western music since the Renaissance has been based on a seven-note scale known as the diatonic scale, but when did the scale originate?  ---question
A fragment of a bone flute excavated at a Neanderthal campsite has four holes, which are spaced in exactly the right way for playing the third through sixth notes of a diatonic scale.  ---evidence
The entire flute must surely have had more holes, and the flute was made from a bone that was long enough for these additional holes to have allowed a complete diatonic scale to be played.  ---evidence
Therefore, the Neanderthals who made the flute probably used a diatonic musical scale.---conclusion

2. 55''
premise: Putting a collar on a rhinoceros involves immobilizing the animal by shooting it with a tranquilizer dart
premise:Female rhinoceroses that have been frequently recollared have significantly lower fertility rates than uncollared females
conclusion:  some substance in the tranquilizer inhibits fertility
Q:evaluate
prephrase: 果推因，指出他因，或有因无果，无因有果
what if people use a tranquilizer dart to immobile rhinoceroses for  other reasons other than recollaring

3. 41''
premise: 烟税每包上升了8分，销售量上升了10%，而去年销售量相比之前下降了1%
conclusion：每包烟税后价格和销售量有密切关系
Q：support
prephrase: 税上升了，但是万一税前价格也变化了呢？

4.41’‘
premise：若果提供手推车那么超市的顾客数量会增加
premise: 增加的人数的花费刚好cover掉提供手推车的成本
conclusion：提供手推车依然可以获得更多利润
Q:explain
prephrase: 使用手推车能增加顾客购买量
