1【大全-A-2】. Which of the following best completes the passage below?
One tax-reform proposal that has gained increasing support in recent years is the flat tax, which would impose a uniform tax rate on incomes at every level. Opponents of the flat tax say that a progressive tax system, which levies a higher rate of taxes on higher-income taxpayers, is fairer, placing the greater burden on those better able to bear it. However, the present crazy quilt of tax deductions, exemptions, credits, and loopholes benefits primarily the high-income taxpayer, who is consequently able to reduce his or her effective tax rate, often to a level below that paid by the lower-income taxpayer. Therefore, ______


Answer：the progressive nature of our present tax system is more illusory thanreal
2.【大全2-2-1】After the national speed limit of 55miles per hour was imposed in 1974, the number of deaths per mile driven on ahighway fell abruptly as a result. Since then, however, the average speed ofvehicles on highways has risen, but the number of deaths per mile driven on ahighway has continued to fall.
Which of the following conclusions can beproperly drawn from the statements above?


Answer：The speed limitalone is probably not responsible for the continued reduction in highway deathsin the years after 1974.
3.【大全2-2-2】Neighboring landholders: Air pollutionfrom the giant aluminum refinery that has been built next to our land iskilling our plants.
Company spokesperson: The refinery is notto blame, since our study shows that the damage is due to insects and fungi
Which of the following, if true, mostseriously weakens the conclusion drawn by the company spokesperson?


Answer：Air pollutionfrom the refinery has changed the chemical balance in the plants’ environment,allowing the harmful insects and fungi to thrive.


4.[GWD #29-Q28]Astronomer: Observations of theShoemaker-Levi comet on its collision course with Jupiter showed that the cometbroke into fragments before entering Jupiter's atmosphere in 1994, but they didnot show how big those fragments were. In hopes of gaining some indication of the fragments' size, astronomersstudied spectrographic analyses of Jupiter's outer atmosphere.  These analyses revealed unprecedented tracesof sulfur after the fragments' entry. The fragments themselves almostcertainly contained no sulfur, but many astronomers believe that the cloudlayer below Jupiter's outer atmosphere does contain sulfur.  Since sulfur would have seeped into the outeratmosphere if comet fragments had penetrated this cloud layer, it is likelythat some of the fragments were at least large enough to have passed throughJupiter's outer atmosphere without being burned up.


Answer:The first is a judgment advanced in support of the conclusion of the argument; the second is that conclusion

5.The following appeared aspart of an article in a magazine devoted to regional life.
“Corporations should look to the city of Helios when seeking newbusiness opportunities or a new location. Even in the recent recession,Helios’s unemployment rate was lower than the regional average.

1.【1‘20s】一个税收改革要向不同收入阶层的人征收同样的税。--》但是有反对者认为，根据收入不同来征收不同的税会更加公平。--》但是，。。。的收入是来自于高收入者的税收，因为高收入者交的税往往比低收入者的多。因此：根据不同的收入层次征税不一定更加的公平。
2.【30s】自从限速政策在1949年开始实施以后，每公里的死亡人数有很大的下降--但是，自从之后，车的平均速度都提高了，但是每公里死亡率还是下降的。
Conclusion：大部分的死亡都是由于高于限速的速度导致的。
3.【20s】地主：因为旁边的铝厂排放的污染气体杀死了我们的植物。
公司，经过我们的调查，不是空气造成死亡，而是植物和细菌造成了植物的死亡。
weaken：污染的气体引起了植物和细菌的滋生。
4.【1’30s】宇航员：在研究彗星撞击的碎片到木星上的时候，无法估计碎片的大小。--》因此科学家开始研究，发现本身不带有S的碎片，带有S。--》而木星大气中有S，只有当碎片穿过大气，进入木星的时候，碎片才会包含S。--》所以，有些碎片足够大到进入木星大气时，并没有完全的燃烧掉。
第一个：支持结论的论据
第二个：结论。

小抽

1 43s
premise:以前递增的纳税方法，由于对于高收入的人群有很多的利好政策，使得他们比低收入的有效税率更低

premise：限速之后，highway per mile死亡率下降，但是平均速度上升了，还是下降
conclusion：死亡率是由于高于限速的那部分速度导致的

3 45s
premise:insects 影响了植物的生长
conclusion the refinery should not to blame

weaken: 附近的insect都是由于the refinery 带来的

4 看不懂啊，放弃啊
这一道题first bolfold is finding ，第二个一个evidence/claim support the astronant argument

premise：有一个彗星的撞击，想测量碎片的额size,因为some of the fragments were at least large enough to have passed throughJupiter's outer atmosphere without being burned up.
