标题: 请教各位NN几个GWD题，不太理解题目意思

    请好心的NN帮我看看这几道题，题目意思都不太理解~能否告诉我下题目大概意思及正确选项的分析？  非常非常谢谢各位！！！

GWD17-Q11:
                                

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

 

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

 

A.      Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.

B.      It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
                            

C.      The number of snow geese taken by hunters each year has grown every year for several years.

D.     As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.

E.In the snow goose’s winter habitats, the goose faces no significant natural predation、

 

T-9-Q33.
                                    

Which of the following, if true, most logically completes the passage?      选A

A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province’s highways and were willing to help pay for the expansion through an increase in their taxes. Nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because       .

  1. most of people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience.

  2. of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other.

  3. the twice-daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years.

  4. expanding the commuter rail system will require the construction of dozens of miles of new railroads.

  5. the proposed expansion to the commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail.

 

GWD-12-Q11:

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.

Which of the following, if true, most strengthens the argument?    选B

  1. The current student-teacher ratio at Vargonia’s government-funded schools is higher than it was during the most recent period of economic recession.

  2. During recent periods when the Vargonian economy has been strong, almost 25 percent of Vargonian children have attended privately funded schools, many of which charge substantial fees.

  3. Nearly 20 percent more teachers are currently employed in Vargonia’s government-funded schools than had been employed in those schools in the period before the last economic recession.

  4. Teachers in Vargonia’s government-funded schools are well paid relative to teachers in most privately funded schools in Vargonia, many of which rely heavily on part-time teachers.

  5. E.During the last economic recession in Vargonia, the government permanently closed a number of the schools that

 

GWD-12-Q38:

Outbreaks of Rift Valley fever occur irregularly in East Africa, several years apart.  When outbreaks do occur, they kill thousands of cattle.  A livestock vaccine against the disease exists but is rarely used.  It is too expensive for farmers to use routinely, and since it is not effective until a month after vaccination, administering it after an outbreak begins helps very little.  Nevertheless, experts predict that use of the vaccine will increase significantly within the next few years

Which of the following, if true, provides the strongest justification for the experts’ prediction?    选E

  1. Rift Valley fever is spread by mosquitoes, but each outbreak is so widespread that it is impractical to control it by using insecticides.

  2. When an outbreak of Rift Valley fever occurs, unaffected countries often refuse to import livestock from the countries affected by the outbreak.

  3. It would take less than a month for producers of the vaccine to adjust their production operations to cope with a large increase in demand.

  4. Many cattle farmers in East Africa are nomadic or live in remote villages, and such farmers, who have little access to modern veterinary medicine, are particularly hard hit by outbreaks of Rift Valley fever.

  5. Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever.

第一题 MM请移步  http://forum.chasedream.com/dispbbs.asp?boardID=24&ID=327897&page=1 有解释

第2题  A说大多数支持的人都是表示“高速公路的拥堵情况好转(during their highway commute)是他们would experience”的，也就是说这群人都想着是自己在高速路上，然后还不堵车。说白了，大家都巴望这人家去坐火车自己上高速开小车……
于是就算complete了，也许还是不会好转

第3题B说在经济好的时期25%的学生上私立学校，学费巨贵的那种 现在经济不好了学生很多去私校念书的学生多半会回到公立学校那里，那么学生就会更多，对老师的需要也就增加了。正是为此，经济不景更加不会令到公立学校对老师的需求的减少。 所以支持观点that current student-teacher ratios not be exceeded.

第4题肯定是E啊 结论是 that use of the vaccine will increase significantly within the next few years而E说

  • Recently published research has shown that certain identifiable climatic conditions are almost invariably followed, within two to five months, by an outbreak of Rift Valley fever. 气候有规律的变化了所以。。。。

    实在太谢谢这位GG这么耐心地回复 ~~ 前几题都清楚啦

    不过最后一题意思是说 fever不光对cattle造成威胁，还引起了气候的变化，所以更有必要用vaccine了，是这个意思吗？

    作者: sunjin1988    时间: 2009-10-21 01:31

     因为以前人们的观点是Outbreaks of Rift Valley fever occur irregularly in East Africa, several years apart. 所以人们抱着侥幸的心理认为他无关紧要 大概就是这个意思吧

    但是现在invariably followed,这个 注意这句话Outbreaks of Rift Valley fever 很有规律了 所以随时有可能攻击动物
