巧用GMAT逻辑机经备考

　　出国留学就读商学院，要么参加GMAT考试，要么参加GRE考试，总之必须要二选一做为必备条件。GMAT逻辑题作为GMAT考试题型中的一种，大家都如何复习呢?留学360专家相信大家的首选就是GMAT逻辑机经，毕竟GMAT逻辑真题永远是最可靠的检验工具。

　　下面是小编整理的2015-11-2最新更新的GMAT逻辑机经，看考生们回忆的GMAT逻辑真题：

　　1. 安全带

　　V1

　　有一道是讲系安全带，一个人说学生坐校车系安全带不容易出事故，还有个人说有次出事学生寄了安全带还是没用，问两个人 disagree 的点好像。

　　V2

　　A 说：学生坐校车/公交车应该系安全带，不容易出事故/更安全/能够减少事故中受到的伤害.

　　B 说：系安全带并不意味着更安全，上周发生的车祸，受伤的学生都是因为系了安全带没能逃脱而受伤的/困在车里而死掉的。

　　问：A 和 B 这两个人 disagree 的点是什么? 这两个人都 disagree 什么?这两个人就哪个事实又不一样的见解?两个人无法就哪一项达成一致?。

　　选项有:

　　校车上系安全带带来的伤害是否要大于它所能预防的。

　　公交车上系安全带和不系安全带哪个安全。

　　安全带是否能保护孩子。

　　公交车里和上下车时的不同安全情况。

　　开公交的司机是否更喜欢系安全带的。

　　大家都说选 B

　　考古

　　V1

　　A：校车上小朋友们要寄安全带，这样能减少车祸发生时的受伤程度哦~

　　B：可是有一次一辆校车翻倒了，小朋友们尽管寄了安全带但还是伤得很惨哦~

　　问：这两位童鞋就哪个事实有不一样的见解?哪个选项可以帮助 evaluate 这个结论。

　　狗主答案：校车上寄安全带带来的伤害要大于它所能预防的。(有点差强人意，不过别的答

　　案我感觉更不对)

　　2.车事故

　　V1

　　是那个车事故的，三个车厢的比其他的更不容易发生事故。

　　选的是开这种车的是更有经验的司机。

　　V2

　　两门的汽车与四门的汽车。两门的汽车开始使用后，事故发生的数量上升。结论：两门的汽车不安全。问削弱。

　　我选的 A：两门汽车受 25 岁以下人欢迎，而这些喜欢开上高速公路，而高速公路是事故多发地段。

　　考古

　　V1

　　In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria’s roads but are involved in 12 percent of all highway fatalities. The very largest trucks-those with three trailers-had less than a third of the accident rate of single-and double-trailer trucks. Clearly,therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.

　　Which of the following, if true, most seriously weakens the argument?

　　A. Partorian trucking companies have so far used triple-trailer trucks on lightly traveled sections of major highway only.

　　B. No matter what changes Partoria makes in the regulation of trucking, it will have to keep some smaller roads off-limits to all large trucks.

　　C. Very few fatal collisions involving trucks in Partoria are collisions between two trucks.

　　D. In Partoria, the safety record of the trucking industry as a whole has improved slightly over the past ten years.

　　E. In Partoria, the maximum legal payload of a triple-trailer truck is less than three times the maximum legal payload of the largest of the single-trailer trucks.

　　V2

　　考题题目没变，答案问题变了

　　A: The government will restrict trucks in the smaller roads.

　　B: The company always use careful and experienced drivers to drive triple trucks.

　　C 还是原文的 C

　　楼主选择 B

　　V3

　　别的狗补充：政府一般限制不让三厢卡车在小路上行驶(个人认为不对)

　　3. 浮游生物

　　V1

　　浮游生物在高与低

　　V2

　　某浮游植物含生长于氮较多的水面上，某地氮含量较多但该植物却不多，科学家发现是因为铁含量不足。于是科学家往这种含氮量较多地方投含铁物质却发现该植物没有生长起来，但是其这个实验有个漏洞。

　　我选的：海潮把睡眠的铁元素卷到了深海。

　　考古

　　V1

　　说一个海滩有大量浮游生物(或者微生物什么的)聚集，有人调查发现没有浮游生物聚集的

　　区域缺铁。于是科学家做了实验，把铁注入某个海域，结果发现还是没有浮游生物聚集，问

　　解释。

　　答案是注入的铁在几天内被洋流冲走了。

　　V2

　　Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface, where plankton live. Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving. However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.

　　Which of the following, if true, argues most strongly against concluding, on the basis of the information above, that the oceanographers’ hypothesis is false?

　　A. Not all of the nitrogen compounds that are sometimes found in relatively high concentrations in the oceans are nutrients for plankton.

　　B. Certain areas of the ocean support an abundance of plankton despite having particularly low concentrations of iron.

　　C. The release of the iron compounds did not increase the supply of nitrogen compounds in the area.

　　D. A few days after the iron compounds were released, ocean currents displaced the iron-rich water from the surface.

　　E. The iron compounds released into the area occur naturally in areas of the ocean where plankton thrive.
