A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters in Belukia‘s territorial

waters had sharply declined by 1996 B. The average annual lobster catch, in tons, of an outlaw fishing boat is has increased steadily since 1992. C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats. D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.

E. A significant proportion of Belukia‘s operators of licensed lobster-fishing boats were out of business between 1992

and 1996

题目里好象没有说1992年以来非法捕捞平均量在STEADILY增加吧，这个STEADILY是很有问题的啊。

A的意思是，非法捕捞并没有多到让龙虾数量急剧减少的程度。这样就正好说明了题意，因为龙虾总数量不变，合法捕捞减少的龙虾数量就正好被非法捕捞的人给弄走了。 文章说：1996年比1992年少了9000吨

前提是，1996年的量和1992年的量是一样的，这样的话，才会有9000吨的差距

A：就是在说1996年的龙虾量和1992年的龙虾量是差不多的，这样的话，比较才有了基础

T-9-Q25. Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. However, a study has found that almost all scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs. Since creative breakthroughs by scientists under forty also generally occur within a dozen years of the scientists’ entry into the field, the study‘s finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.

In the argument given, the two portions in boldface play which of the following roles? A. The first is the position that the argument as a whole depends; the second is evidence that is advanced as part of

that evidence. B. The first and second are both claims that have been advanced in support of a position that the argument as a whole

opposes. C. The first is an explanation that the argument challenges; the second provides evidence in support of a competing

explanation that the argument defends. D. The first is an explanation that the argument challenges; the second is evidence that has been used against an

alternative explanation that the argument defends. E. The first is an explanation that the argument defends; the second is evidence that has been used to challenge that

explanation.

T-9-Q28. 天山-7-13 Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice. However, certain other species on which the larvae feed do

27

not harbor the bacterium. Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline. Which of the following, if true, most strengthens the argument?

A. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans. B. There are no known cases of a human‘s contracting Lyme disease through contact with white-footed mice. C. A deer tick feeds only once while in the larval stage.

D. A single host animal can be the source of bacterium for many tick larvae.

E. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans

其实该题单纯从有关无关就可以找到答案C

原文推理是：1。T传细菌给人类，人类感染L病。2。T在幼虫是吃M就带该细菌。3。幼虫吃其它东西不带该细菌。所以（结论），其他东西多拉，携带该细菌的T就少，人类感染L病的机会也少。

A。无关。T携带该细菌是否有反作用和结论无关

B。无关。主要有两个因素决定和结论无关。1是原文讨论的是T传细菌给人类导致人类得L病，人类直接接触M 是否得L病与原文无关。2是知不知道有没有这样的CASE并不代表实际有没有，所以对原文不起作用。

C。支持。T 在幼虫期只是进吃一次。既然只吃一次，这次不是吃M就是吃其他东西，当其他东西变多时，吃M的机率就变少，所以T感染该细菌就少。支持结论 DE都无关。

T-9-Q30. The percentage of households with an annual income of more than $40,000 is higher in Merton county than in any other county. However, the percentage of households with an annual income of $60,000 or more is highest in Sommer county. If the statements above are true, which of the following can properly be concluded on the basis of them?

A. No households in Merton county has an annul income of $60,000 or more

B. Some households in Merton county have an annual income between $40,000 and $60,000

C. The number of households with an annual income of more than $40,000 is greater in Merton than in Sommer

county. D. Average annual household income is higher in Sommer than in Merton county.

E. The percentage of households with an annual income of $80,000 is higher in Sommer than in Merton county.

这题相当于数学里头的DS：）

两个条件：1、M county年收入在40000刀以上的家庭比例高于其他county（也就是最高）； 2、S county 年收入在60000刀以上的家庭比例最高 两个county斗富，看能推出啥结果。

28

A M里头没有收入高于60000的——显然不对；

B M里有人家收入在40000-60000——根据条件1能成立；

C M里收入40000以上的家庭数目比S多——条件给的是百分比，不是绝对数量；

（这个比较经典，经常通过百

分比，来错误比较实际数量）

D S的家庭平均年收入比M高——这个要看穷人还有多少，虽然他们高收入的人多（条件2），万一穷人更多，平均收入就很难说； E S里收入80000以上的比M多——不能推出。举个例子：M收入60000以上的有15％，S有16％（符合条件2），但是M这个地方有好多大款，收入80000以上的占14％，也就是说只有2％收入在60000-8000；而S这个地方贫富差距小，收入80000以上的大款 …… 此处隐藏：6986字，全部文档内容请下载后查看。喜欢就下载吧 ……
