33. Art restorers who have been studying the factors that cause Renaissance oil paintings to deteriorate physically when subject to climatic changes have found that the oil paintused in these paintings actually adjusts to these changes well. The restorers therefore hypothesize that it is a layer of material called gesso, which is under the paint, that causes the deterioration. Which of the following, if true, most strongly supports the restore rs' hypothesis? (A) Renaissance oil paintings with a thin layer of gesso are less likely to show deterioration in response to climatic changes than those with a thicker layer. (8) Renaissance oil paintings are often painted on wooden panels, which swell when humidity increases and contractwhen it declines. (C) Oil paint expands and contracts readily in response to changes in temperature, but it absorbs little water and so is little affected by changes in humidity. (0) An especially hard and nonabsorbent type of gesso was the rawmaterial for moldings on the frames of Renaissance oil paintings. (E) Gesso layers applied by Renaissance painterstypically consisted of a coarse base layer onto which several increasingly fine-grained layers were applied .
34. If the airspace around centrally located airports were restricted to commercial airliners and only those private planes equipped with radar, most of the private-plane traffic would be forced to use outlying airfields. Such a reduction inthe amount of private-plane traffic would reduce the risk of midair collision around the centrally located airports. The conclusion drawn in the first sentence depends onwhich of the following assumptions? (A) Outlying airfields would be as convenient as centrally located airports for most pilots of private planes. (8) Most outlying airfields are not equipped to handle commercial-airline traffic. (C) Most private planes that use centrally located airports are not equipped with radar. (D) Commercial airliners are at greater risk of becoming involved in midair collisions than are private planes . (E) Areduction in the risk of midair collision would eventually lead to increases in commercial airline traffic.
35. Two decades after the Emerald River Dam was built, none of the eightfish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reprodu ctive cycle. Which of the following statements, if true, would most strengthen the scientists' hypothesis? (A) The native fish species were still able to reproduce only in side streams of the riverbelow the damwhere the annual temperature range remains approximately 50 degrees. (B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish . (e) The lowest recorded temperature of the Emerald River before the dam was builtwas 34 degrees, whereas thelowest recorded temperature of the river after the damwas built has been 43 degrees. (D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space. (E) Five of the fish species native to the Emerald River are not native to any other river in North America.
36. Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs' airways to contract. This partially seals off the lungs. An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust. Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent bythemessenger molecules referred to above? (Al Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks. (8l Researchers do not yet knowwhatmakes one person's messenger molecules moreeasily activated than another's. (C) Such a medication would not become available for several years, because of long lead times in both development and manufacture. (0) Such a medication would be unable to distinguish betweenmessages triggered by pollen and household dust and messages triggered bynoxious air. (El Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started. 1AA:.本月机经7次
原题：The country of Bonaria held a major soccer event five yearsago. Therefore, if the country continues to hold major sport events, tourismwill increase rapidly in the country and thus bring benefits to the country'seconomy. 提供观点： 1、错误的由时间先后推出因果关系
1/50s P: The oil painting used to adjust its paint with the climate. C: The layer of material called gesso makes the painting deteriorate. S: The oil painting with this layer is easily to deteriorate than the one without this layer. A:A B:another reason, weaken C:the statement is irrelevant D:it's the usage about the G, irrelevant E:there is nothing about the consistence of the G in the argument.
2/60' P:most private-plane traffic would be forced to use outlying airfields C:If those airports use radar, it would reduce the risk of collision A:the author said that if force to use radar, it would reduce the risk, it means that the airport didn't have radar yet. A:C A:irrelevant But the scope D:irrelevant E:wrong argument
3/1'20 P:non of the eight fish species are still reproducing below the dam C:the rising of the water temperatures must be led to the species changes. S:it should show the relationship between the water temperatures and the reproduce of the fish A:A B:weaken C:it's just about the temperatures ,it's irrelevant D:the stimulus is about the native fish,this is out of scope E: irrelevant
4/1'02 P1:certain molecules make lungs off in response to noxious air P2:an asthma happens when certain molecules act unnecessatily in response to pollen or dust F：if a new medicine have been produced to prevent asthma attacks but by blocking any message molecules response, what will be flaw?----it will led to wrong response to noxious air and harmless air. A:irrelevant B:irrelevant C:don't explain the issue E:no mention in the stimulus
AA: 1、a event got achievement five years ago can not deduce that it will be also success now 2、maybe there are other ways to get the success.
5. 1.a sports event achieve success five years ago can not guarantee it will achieve same success now. 2.hold sports event may lead disadvantage overweight to the advantage: environmental pollution. 3.the main reason of the tourism may not hold the sports event, there may be other better way.
bala, 我觉得33题D选项无关的，因为题目说的是a layer called gesso under the oil painting, 可是D是：An especially hard and nonabsorbent type of gesso was the raw material for moldings on the frames of Renaissance oil painting. 所以这个说layer在frame上面，那么位置不同，所以不能由在frame上面就推断对oil painting的影响。第一次做这道题目时也犯了和bala同样的错误呢。

1.【38s】 P：a painting deteriorates when it comes to climate change-->oil painting keep well when it face cliamte C: gesso cause the deteriorate. Support: there is no gesso in the oil painting. (......我也想说被忽悠了~读题的时候，理解成油画不容易腐烂，原来是油画材料。。。还有这道题，如果没有A选项，是不D也是可以的？？？？？） 2.【31s】 P:airports restricted to the commercial airlines and private airlines with radar---->less private airline traffic C:less collision. assumption: the main cause of the collision is the too much private plane. (也是和我想的不一样，这里的搭桥是条件之间的桥，而非条件和结论间的桥） 3.【27s】 P：built a dame-->fish reproductive rate decrease. C: temperature change---> reproductive change. support: provide an exact example that temperature is the cause of the reproductive change. 4:[50s]这道题学术了~~读了两遍~~额~~~ P：molecules fight poisonous air-->lungs airway increase asthma occur when molecules active unnecessary. C：a medicine will prevent asthma trough block any messages weaken: asthma sometimes have benefit to health.（又偏了~~ 额·~）
1. 27s premise-art restorer found that paintings resist to climate change well. conclusion-art restorer hypothesize that it's a material called G causes the damage to painting. guess support: painting with G has damages but painting with out G doesn't suffer from damage. both of the paintings resist to climate change well. A
2. 31s -airport is centrally restricted to commercial airplanes. -those private airplanes go outfield. -conclusion: less collision. guess assumption: collisions happen mostly between commerical airplane and private airplane, instead of between two commercial airplane or two private airplane. D
3. 34s -after the dam was built, the fish's reproduction rate declined. -the dam caused the water temperature to change from 50 degree to 6 degree. -scientists hypothesize that it's the dam that caused the decline. guess support: no idea...maybe to strength the reasoning that it's the dam that directly caused the temperature change, or it's the temperature change that directly caused the problem. E 哎，不知道，这题整个混乱，看了第三遍觉得选A。。。
4. 60s!!!! -XX fight damage to lung's XX by shut up the airway -asthma activate the airway, allowing harmless particles such as pollen to get in. -forgot!!! guess flaw: no idea... A
