When positive integer x is divided by positive integer y, the remainder is 9. If x/y = 96.12, what is the value of y?96 75 48 25 12 X=(96+0.12)Y0.12Y=9Y=75The figure above shows the dimensions of a semicircular cross section of a one-way tunnel. The single traffic lane is 12 feet wide and is equidistant from the sides of the tunnel. If vehicles must near the top of the tunnel by at least foot when they are inside the traffic lane, what should be the limit on the height of vehicles that are allowed to use the tunnel?5 ft 7 ft 8 ft 9 ft 10 ft 理解问题：要画图：单的轨道是12feet而且等距，半圆形隧道里面还有一个长方形的轨道，从圆心开始从左从句开始延展6，以圆心垂直于半径为对称轴向上做垂线，由于大圆半径是10，所以高是8，车要低于0.5米，所以是7.5米，关键是那句话怎么理解。The operation is defined for all nonzero numbers a and b by a b = a/b b/a. If x and y are nonzero numbers, which of the following statements must be true?I. x xy = x(1 y)II. x y = -(y x)III. 1/x 1/y = y xI only II only III only I and II II and III I. x xy = x(1 y)左=X/XY-XY/X=1/Y-Y右=X（1/Y-Y/1),X消不掉，因此两边不等II. x y = -(y x) 成立III. 1/x 1/y = y x 成立后面懒得再做了，就是把握a b = a/b b/a这样的定义，代入化简变形即可，选E 把xy当成整体来做If a and b are positive, is less than?(1) a = 2b(2) a + b 1Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. EACH statement ALONE is sufficient. Statements (1) and (2) TOGETHER are NOT sufficient. 第一式 = ab/(a+b)第二式 = ab/1a、b 为正数 1)第一式 = 2b/3第二式 = 2b*b无法比较两式大小2）a + b 1 so 1/(a+b) 1/1soab/(a+b) LC条件也不够 Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. EACH statement ALONE is sufficient. Statements (1) and (2) TOGETHER are NOT sufficient. profit=500,000-C(m+l)ClCm:Cl=1:2Cm200,000What is the median number of employees assigned per project for the projects at Company Z?(1) 25 percent of the projects at Company Z have 4 or more employees assigned to each project.(2) 35 percent of the projects at Company Z have 2 or fewer employees assigned to each project. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient. EACH statement ALONE is sufficient. Statements (1) and (2) TOGETHER are NOT sufficient. 25%大于等于4，35%小于等于2，中间不就剩下3了么，选CVERBALNeither First Lady Eleanor Roosevelt nor Secretary of Labor Frances Perkins sought recognition by the press, and both cautiously allowed others of the Roosevelt brain trust to take credit for the genesis of historic programs in public employment, relief, and social security that were in large measure what they had been responsible for. to take credit for the genesis of historic programs in public employment, relief, and social security that were in large measure what they had been responsible for 这个东西很大程度上是他们负责的东西 to take credit for the genesis of historic programs in public employment, relief, and social security for which the two women were in large measure responsible 这个东西是他们负责的 taking credit for the genesis of historic programs in public employment, relief, and social security for which the two women were in large measure responsible taking credit for the genesis of historic programs in public employment, relief, and social security that were in large measure what they were responsible for taking credit for the genesis of historic programs in public employment, relief, and social security which were largely their responsibility 允许某人干一件事情，先被allowed允许再去干Sunflowers growing in pots were placed, with their roots submerged, in the pond contaminated with radioactive elements. The sunflowers kept growing; in the process, they absorbed radioactive elements. Within twelve days, 85 percent of the radioactive elements were removed from the water, which is no less than can be accomplished with the much more expensive conventional filtration techniques. Scientists therefore propose using sunflowers for decontamination wherever there are radioactively contaminated ponds.Which of the following, if true, points to a limitation on the applicability of the proposed method of decontamination? ASome plants other than sunflowers can also remove radioactive elements from water. 范围不对 BThe water in many ponds contaminated with radioactive elements is so cold that it would kill sunflowers whose roots were submerged in it. 强调不是水凉的问题，而是它能杀死一些根没进去的向日葵，重点在后面。与原文有点关系了，先留着。 CSunflowers that grow with their roots submerged in water grow less well than sunflowers growing under optimal conditions on dry land.原文没说向日葵在dry land，范围出去了。DOnly species of sunflowers with large leaves can have their roots submerged in water and still keep growing. 不会因为only把D杀掉，而是比主体。只有大叶的向日葵根没进去，上来要是因为only就扔选项，就是套路。虽然讲大叶的向日葵，选项的范围只要和原文的范围有点关系就行，沾点边。 EIn ponds in which the circulation of the water is artificially increased, sunflowers absorb radioactive elements far faster than they do in other ponds.范围不对，原文之说这池塘，没说其他池塘，扔掉。 逻辑原文整体就是讲向日葵把根没进去了，将会吸收放射性元素。一遍能看出来驳斥或支持就看，看不出来就看有关无关。B D相同点是向日葵是没不没进去，去掉以后B剩下向日葵这个主体，D就是大叶的向日葵，B好启示：要关注句子的整体意思。Not one of the potential investors is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were not to be concluded. 如果划线部分的打头词是V或者划线结尾词如果是V的话，要考虑什么用来扔一些选项？看到V想发起者，IS就能杀DE is expected to make an offer to buy First Interstate Bank until a merger agreement is signed that includes a provision for penalties if the deal were 证明是虚拟语气，事情没发生 is expected to make an offer for buying First Interstate Bank until they sign a merger agreement including a provision for penalties if the deal was 过去式，事情已经发生了 is expected to make an offer to buy First Interstate Bank until a merger agreement be signed by them with a provision for penalties if the deal were are expected to make an offer for buying First Interstate Bank until it signs a merger agreement with a provision for penalties included if the deal was are expected to be making an offer to buy First Interstate Bank until they sign a merger agreement including a provision for penalties if the deal were 根据语意，事情还没发生，故应该用were，A比B好，AC开比，区别是C多了一个By them，会让人产生无限遐想，还要琢磨一下，故A好On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks. A On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow 问题没有马上解决B On Earth, among the surest indications of sunspot cycles are, it is believed, the rate of tree growth C On Earth, the rate at which trees grow is believed to be among the surest indications of sunspot cycles D Among the surest indications on Earth of sunspot cycles, believed to be the tree growth rate believe发起者不知道是谁，杀 E Among the surest indications on Earth of sunspot cycles is believed to be the rate at which trees grow 答案是比出来的，真正的道理是暗示，原文和选项都可能有暗示。暗示是选项的区别和语意上的对应关系。AS 是对比，树的生长率就像被看到像树干上的生长年轮一样，as seen前谁说树的生长率谁更好，E比C好。不用固定的套路做题，而是对方告诉你怎么解题，无招胜有招。As引导前后的的一致性。在什么地看到的什么东西就像在什么地看到的什么东西一样。Among在前，E好。The total market value of real estate in Altonville has steadily declined over the past four years. This decline has meant that the overall figure on which the citys property tax is based the assessed value of that real estate has also declined. Moreover, the percentage of assessed value that was paid as property taxes to the city did not change during this period.The information above most strongly supports which of the following? 上支持下 A Money collected from property taxes provided most of Altonvilles revenue during the past four years. B The percentage of Altonvilles overall revenue that was collected from property taxes did not change over the past four years. 百分比变不变 C Altonville officials had proposed raising property tax rates during the past four years but never did so because of strong opposition from property owners. D The total amount of revenue that Altonville has collected from property taxes has declined over the past four years. 总钱数变不变，总figure E During the past four years, Altonville officials also did not increase tax rates on other sources of revenue such as retail sales or business profits. 没有方法加情商的心态。两个东西减少，但是百分比没有变。比较B和D，一个除一个，分子分母都告诉我变化，才能知道比例不变。The total amount of revenue钱数少了，就是总钱数乘以百分比，D比B好。出题者怎么设置干扰选项：张冠李戴：某个词见过，但不是正确选项，即1号事情安到2号事情上。做题时但凡有些选项有些混淆性时，要注意是否张冠李戴。B的百分比不可能获知，只是知道the percentage of assessed value有没有变。The passage is primarily concerned withPassage Scientists generally credit violent collisions between tectonic plates, the mobile fragments of Earths rocky outer shell, with sculpting the planets surface, as, for example, when what is now the Indian subcontinent collided with Asia, producing the Himalayan Mountains. However, plate tectonics cannot fully explain certain massive surface features, such as the superswell of southern Africa, a vast plateau over 1,000 miles across and nearly a mile high. Geologic evidence shows that southern African has been slowly rising for the past 100 million years, yet it has not experienced a tectonic collision for nearly 400 million years.The explanation may be in Earths mantle, the layer of rock underlying the tectonic plates and extending down over 1,800 miles to the outer edge of Earths iron core.第一句话总能读出板块冲撞，HOWEVER后读一下，这个理论解释不了地球表面特征，就是文章主旨 Since the early twentieth century, geophysicists have understood that the mantle churns and roils like a thick soup. The relative low density of the hottest rock makes that material buoyant, so it slowly ascends, while cooler, denser rock sinks until heat escaping the molten core warms it enough to make it rise again. While this process of convection was known to enable the horizontal movement of tectonic plates, until recently geophysicists were skeptical of its ability to lift or lower the planets surface vertically. However, recent technological advances have allowed geophysicists to make three-dimensional snapshots 像细节of the mantle by measuring vibrations, or seismic waves, set in motion by earthquakes originating in the planets outer shell and recording the time it takes for them to travel from an earthquakes epicenter to a particular recording station at the surface. Because geophysicists know that seismic waves become sluggish in hot, low-density rock, and speed up in colder, denser regions, they can now infer the temperatures and densities in a given segment of the interior. By compiling a map of seismic velocities from thousands of earthquakes across the globe, they can also begin to map temperatures and densities throughout the mantle. These methods have revealed some unexpectedly immense formations in the deepest parts of the mantle; the largest of these is a buoyant mass of hot rock directly below Africas southern tip. Dis-pelling researchers initial doubts, computer models have confirmed that this formation is buoyant enough to rise slowly within the mantle and strong enough to push Africa upward as it rises. 第二段都是细节 A describing a traditional explanation for the vertical movement of Earths surface 去掉虚词，地球表面的垂直运动，文章没提到，杀 B discussing recent geophysical research that may explain certain features of Earths surface that were previously difficult to account for 去掉虚词，解释一定特征，以前无法解释，沾边 C combining elements of several theories in order to develop a plausible explanation for a poorly understood feature of Earths surface 有点像，放着 D providing new evidence in support of a long-standing belief about how certain of Earths massive surface features were created 没BC虚，扔 E questioning the implications of geophysicists recent findings regarding the composition and density of Earths mantle 从头到尾都没读到，杀B和C谁虚，B更好。The city of Workney, in raising bus fares from $1.00 to $1.25, proposed that 18 fare tokens be sold for $20.00 to alleviate the extra burden of the fare increase on the citys low-income residents. Critics suggested alternatively that 9 fare tokens be sold for $10.00, because a $20.00 outlay would be prohibitive for low-income riders. The alternative proposal depends on which of the following assumptions? A Low-income residents of Workney will continue to ride the buses in the same numbers despite the fare increase. 强调低收入者坐车的数量是否相同，原文没提到过BLow-income riders would be more likely to take advantage of the savings afforded by the 9-token offer than would other riders. C The outlay of $10.00 for the purchase of 9 fare tokens would not be prohibitive for low-income bus riders.低收入者乘bus能花多少钱的问题，价格本身昂贵不昂贵谈，原文最后清晰的谈过。 DThe proposed fare increase is needed for the purchase of new buses for the citys bus system. EBuses provide the only means of public transportation in the city of Workney. 逻辑题目不是根据内容，这个词是否说过来做题，而是是否围绕原文探讨要抓住逻辑选项的整体意思Prospecting for gold during the California gold rush was a relatively easy task, because of erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach for anybody with a pan or shovel. A because of erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach for读完没感觉，不好说，先放着 B because of erosion, prehistoric glacier movement, and volcanic activity that thrust ancient, gold-bearing riverbeds to the surface, and putting gold literally within reach of and前后没有对应关系，杀 C owing to erosion, prehistoric glacier movement, and volcanic activity that had thrust ancient, gold-bearing riverbeds to the surface, and putting gold literally within reach of and前后没有对应关系，杀 D since erosion, prehistoric glacier movement, and volcanic activity that thrust ancient, gold-bearing riverbeds to the surface, putting gold literally within reach for E since erosion, prehistoric glacier movement, and ancient, gold-bearing riverbeds thrust to the surface by volcanic activity put gold literally within reach of D与E一看就想主谓是否全的问题。D没有谓语v，E更好。选项比较长时专有n不记，And连接的专有n没有任何意义，陈述方式均相同。A与E再比，because of后不能跟句子，杀A。Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides. New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt. Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.整体说用什么东西处理一些东西更好In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT: 找最不可能的 A What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides? 成本 B To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride? 设备能不能干这事 C What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride? 调节政策限制不限制处理这东西 D How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used? 皮毛本身是否有相似度 E Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?化学特征相不相似 ，最远，最不可能。Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development. They plan to do this by purchasing that land from the farmers who own it. That plan is ill-conceived: if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders. On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable. But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires. And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.In the argument as a whole, the two boldface proportions play which of the following roles?A The first presents a goal that the argument rejects as ill-conceived; the second is evidence that is presented as grounds for that rejection. B The first presents a goal that the argument concludes cannot be attained; the second is a reason offered in support of that conclusion. C The first presents a goal that the argument c
