1.天哪，我这第一题翻来覆去看了好久才看明白说的是啥意思。。。这可怎么办。。。到时候考试argument看不懂可咋整！！！
（1）30s weaken
（2）逻辑链
Fact:
<1>LT live and breed in PC & A.
<2>T was feed in BP & hatch in Japan 95% DNA similar to BT taken from Japan
Conclusion:
Juvenile Pacific loggerheads that feed near the Baja Peninsula hatch in Japanese waters 10,000 kilometers away
（3）<1>95%不足够说明他们是同一生物
<2>研究表明，LT这种生物不会出现feed 和hatch隔这么远距离的情况
（4）argument中使用在Japan海中nest中的turtle的DNA与B海中的turtle进行比对，得到他们是一个物种的结论，证明turtle是在B海feed Japan hatch的。
A:意图通过说明turtle也会在NA hatch，但A中没有提到任何关于DNA的问题，loser
B：意图通过类比说明在P中的turtle不会在feed和hatch间隔10000km，但由于举得是AT这个地方LT的例子，因而是错误类比，loser
C：无关比较，将Japan的hatch与B海的nest sites进行对比，loser
D：说明95%的相似度不足够证明B海中的turtle和Japan nest里的是一个品种，contender
E：无关选项，没有提到任何关于DNA和B海中turtle的信息，loser
所以：D正确

2.
（1）45s weaken
（2）逻辑链
Background：
20 & 5 years ago, two times the pundra was weak
primes:
Weak pundra —> increase in manufactured products
Conclusion:
In order to increase the export<— allow the pundra to become weak again
（3）那两次虽然export增加，但是由于pundra was weak，D实际上是亏损很多的
（4）A：意图证明这个recommendation是有效地？loser
B：意图证明即使不使pundra weak again，export也会增加，contender
C：与goal没什么关系，loser
D：other countries跟D国的goal无关，loser
E：另一种增加export的途径，好方法！contender
所以，B只是说到了manufacturing sector的操作，E跟与argument中提到的goal相关，所以E正确
正确答案是B，为啥呢？

3.
（1）45s explain
（2）逻辑链
100 years ago, poor sanitation —> high mortality among the city’s inhabitants—>immigration from rural fueled the population increase
Recent decades, city sanitation improved enormously —/—>population growth
（3）<1>周围rural的人都搬得差不多了
<2>年轻人都不愿意要很多个孩子
（4）A：认为将mortality rates与不良卫生环境的关系比与交通事故的关系要大，loser
B：M地的出生率下降，可以解释为什么卫生条件变好了，但是人口增量下降了，contender
C：无关比较，对于argument没有影响，loser
D：无关，loser
E：如果E正确，M的人口增量应该增加，loser
所以，B正确

4.
（1）45s boldface
（2）逻辑链
Seed expensive & require more fertilizer and water—>farmer prefer pesticide
Consumer prefer products without pesticide—> seed widespread
（3）选E
正确答案，C；黑脸的题应该怎么做呢？

5.
（1）45s must be true
（2）逻辑链
<1>First-time cost much less & smaller profit per computer than replace with more powerful one
<2>Last years, profit higher than before——number of computers sales unchanged & each computer has same profit

Conclusion: The government should allow the pundra to become weak again in order to cause another similarly sized increase in exports.
3）推测：A weak pundra will cause some disadvantages. For example, the export revenue may decrease because the pundra’s value is low relative to the world’s most stable currencies.

Premise：Ninety-five percent of the DNA samples taken from the Baja turtles match those taken from turtles at the Japanese nesting sites.

Conclusion：New evidence suggests that juvenile Pacific loggerheads that feed near the Baja Peninsula hatch in Japanese waters 10,000 kilometers away.

Answer：D

(A) Nesting sites of loggerhead turtles have been found the Pacific coast of North America Several thousand kilometers north of the Baja peninsula.-----------IRRELAVENT
(B) The distance between nesting sites and feeding sites of Atlantic loggerhead turtles is less than 5,000 kilometers.------------ the above argument does not mention Atlantic loggerhead turtles.
(C) Loggerhead hatchlings in Japanese waters have been declining in number for the last decade while the number of nesting sites near the Baja peninsula has remained constant.------------the number decline or remain constant cannot weaken the argument.
