Directions: Each passage in this group is followed by questions based on its content.

After reading a passage, choose the best answer to each question. Answer all questions

following a passage on the basis of what is stated or implied in that passage.

lt has been known for many decades that the appear-

ance of sunspots is roughly periodic, with an average

cycle of eleven years. Moreover, the incidence of solar

flares and the flux of solar cosmic rays, ultraviolet radia-

tion, and x-radiation all vary directly with the sunspot (5)

cycle. But after more than a century of investigation. the

relation of these and other phenomena, known collec-

tively as the solar-activity cycle, to terrescrial weather

and climate remains unclear. For example. the sunspot

cycle and the allied rnagnetic-polarity cycle have been (10)

linked to periodicities discerned in records of such vari-

ables as rainhll. temperature, and winds. lnvariably,

however, the relation is weak. and commonly ofdubious

statistical significance.

Effects of solar variability over longer terms have also (15)

been sought. The absence of recorded sunspot activity in

the notes kept by European observers in the late seven-

teenth and early eighteenth centuries has led some schol-

ars to postulate a brief cessation of sunspot activity at

that time (a period called the Maunder minimum). The (20)

Maunder minimum has been linked to a span of unusual

cold in Europe extending from the sixteenth to the early

nineteenth centuries. The reality of the Maunder mini-

mum has yet to be established, however, especially since

the records that Chinese naked-eye observers of solar (25)

activity made at that time appear to contradict it. Scien-

tists have also sought evidence of long-term solar period-

icities by examining indirect climatological data, such as

fossil recoras of the thickness of ancient tree rings. These

studies, however, failed to link unequivocally terrestrial(30)

climate and the solar-activity cycle, or even to contirm

the cycle’s past existenue.

If consistPn! and re!iab!e geo!sgigal~-arek-xologieal

evidence tracing the solar-activity cycle in the distant

past could be found, it might also resolve an important(35)

issue in solar physics: how to model solar activity. Cur-

rently, chere are two models of solar activity. The tirst

supposes that the Sun’s internal motions (caused by

rotation and convection) interact with its large-scale

magnetic field to produce a dynamo. a device in which(40)

mechanical energy is converted into the energy of a mag-

netic field. ln short. the Sun’s large-scale magnetic field

is taken to be self-sustaining, so that the solar-activity

cycle it drives would be maintained with little overall

changc for perhaps billions of years. The alternative(45)

exp)anarion supposes that the Sun’s large-sca)e magnetic

field is a remnant of the field the Sun acquired when it

formed, and is not sustained against decay. In this

model. the solar mechanism dependent on the Sun’s

magnetiC field runs down more quickly. Thus, the char-(50)

acteristics of the solar-activity cycle uvuld be expected to

change over a long period of time. Modern solar obser-

vations span too short a time to reveal whether present

cyclical solar aCtivity is a long-lived feature of the Sun,

or merely a transient phenomenon.

17. The author focuses primarily on

(A) presenting two competing scientific theories concerning solar

activity and evaluating geological evidence often cited to support them

(B) giving a brief overview of some recent scientifrc developments

in s’olar physics and assessing their impact on future climatological research

phenomena with solar activity and indicating how resolving that issue

could have an impact on our understanding of solar physics

(D) pointing out the futility of a certain line of sci- entific inquiry

into the terrestrial effects of solar activity and recommendine ita

aban- donment in favor of purely physics-oriented research

(E) outlinine the specific reasons why a problem in solar physics has

not yet been solved and faulting the overly theoretical approach of modern

physicists.

18. Which of th.e following statements about the two models of solar

activity. as they are described in lines 37-55, is accurate?

(A) In both modgls cyclical solar activity is regarded as a long-lived

feature of the Sun, persisting with little change over billions of years.

(B) Tn both models the solar-activity cycle is hypothesized as being

dependent on the large-scale solar magnetic field.

causing solar activ- ity, whereas in the other model it is not.

(D) In one model solar activity is presumed to be unrelated to terrestrial

phenomena. whereas in the other model solar activity is thought to have

observable effects on the Earth.

(E) In one model cycles of solar activity with peri- odicities longer than

a few decades are con- sidered to be impossible, whereas in the other model

such cycles are predicted.

19. According to the passage, late seventeenth- and early eighteenth-century

Chinese records are impor- tant for which of the following reasons?

(A) They suggest that the data on which the Maunder minimum was predicated

were incorrect.

(B) They syggest that the Maunder minimum can- not be related to climate.

(D) They establish the existence of a span of unusu- ally cold weather

worldwide at the time of the Maunder minimum.

(E) They establish that solar activity at the tirne of the Maunder minimum

did not significantly vary from its present pattern.

20. The author implies which of the followine about currently available

geological and archaeoloeical evidence concerning the solar-activity cycle?

(A) It best supports the model of solar activity described in lines 37-45.

(B) It best supports the model of solar activity described in lines 45-52.

in the third paragraph.

(D) It contradicts both models of solar activity as they are presented in

the third paragraph.

(E) It disproves the theory that terrestrial weather and solar activitv are

linked in some way.

21. Tt can be inferred from the passage that the argu- ment in favor of the

model described in lines 37- 45 would be strengthened if which of the following

were found ta he tme?

(A) Episodes of intense volcanic eruptions in the distant past occurred in

cycles having very long periodicities.

(B) At the present time the global level of thunder- storm activity increases

and decreases in cycles with periodicities of approximately 11 years.

than 200 years.

(D) In the last century the length of the sunspot cycle has been known to

vary by as much as 2 years from its average periodicity of 11 years.

(E) Hundreds of millions of years ago, solar- activity cycles displayed the

same periodicities as do present-day solap-activity cycles.

22. lt can be inferred from the passage that Chinese observations of the Sun

during the late seventeenth and early eighteenth centuries

(A) are ambiguous because most sunspots cannot be seen with the naked eye

(B) probably were made under the same weather conditions as those made in Europe

(D) record some sunspot activity during this period

(E) have been employed by scientists seeking to argue that a change in solar

activity occurred during this period.

23. It can be inferred from the passage that studies attempting to use tree-ring

thickness to locate possi- ble links between solar periodicity and terrestrial

climate are based on which of the following assump- tions?

(A) The solar-activity cycle existed in its present form during the time period

in which the tree rings erew.

(B) The biological mechanisms causing tree growth are unaffected by short-term

weather pat- terns.

(D) Tree-ring thicknesses reflecr changes in terres- trial climate.

(E) Both terrestrial climate and the solar-activity cycle randomly af~ct tree-ring

thickness.

The common belief of some linguists that each

language is a perfect vehicle for the thoughts of the

nation speaking it is in some ways the exact counterpart

of the conviction of the Manchester school of economics

that supply and demand will regulate everything for the(5)

best. Just as economists were blind to the numerous

cases in which the law of supply and demand left actual

wants unsatisfied, so also many linguists are deaf to

those instances in which the very nature of a ianguage

calls forth misunderstandings in everyday conversation,(10)

and in which, consequently, a word has to be modified

or defined in order to present the idea intended by the

speaker: “He took his stick,no, not John’s, but his

own.” No language is perfec’t, and if we admit this truth,

we must also admit that it is not unreasonable to investi-(15)

gate the relative merits of different languages or of

different details in languages.

As of the late 1980’s. neither theorists nor large-

scale computer climate models could accurately predict

whether cloud systems would help or hurt a warming

globe. Some studies suggested that a four percent

(5)increase in stratocumulus clouds over the ocean could

compensate for a doubling in atmospheric carbon diox-

ide, preventing a potentially disastrous planetwide temp-

erature increase. On the other hand, an increase in cirrus

clouds could increase global warming.

(10) That clouds represented the weakest element in cli-

mate models was illustrated by a study of fourteen such

models. Comparing climate forecasts for a world with

double the current amount of carbon dioxide, researchers

found that the models agreed quite well if clouds were

(15)not included. But when clouds were incorporated, a wide

range of forecasts was produced. With such discrepancies

plaguing the models, scientists could not easily predict

how quickly the world’s climate would change, nor could

they tell which regions would face dustier droughts or

deadlier monsoons.

24.The author of the passage is primarily concerned

with

(A) confirming a theory

(B) supporting a statement

(D) predicting future discoveries

(E) reconciling discrepant findings

25. It can be inferred that one reason the fourteen models

described in the passage failed to agree was that

(A) they failed to incorporate the most up-to-date

information about the effect of clouds on

climate

(B) they were based on faulty information about

factors other than clouds that affect climate.

the overall effects of clouds on climate

(D) their originators disagreed about the kinds of

forecasts the models should provide

(E) their originators disagreed about the factors

6、下列中国古今地名对应不正确的是( )。

A、幽州——洛阳 B、长安——西安 C、大都——北京 D、建业——南京

参考答案及解析

1、【答案】D。解析：“千里之行，始于足下”，出处：《老子》第六十四章：“合抱之木，生于毫末;九层之台，起于累土;千里之行，始于足下。”比喻事情的成功，是从小到大逐渐积累起来的。这是对质量互变规律再实际生活中的体现。故本题答案为D。

2、【答案】D。解析：我国社会已经是社会主义社会，我们必须坚持而不能离开社会主义;我国的社会主义社会还处在初级阶段。我们必须从这个实际出发，而不能超越这个阶段。这里所说的初级阶段，不是泛指任何进入社会主义都会经历的起始阶段，而是特指我国在生产力发展水平不高、商品经济不发达条件下建设社会主义必然要经历的特定历史阶段。因此，D项“快速超越”表述错误，故本题答案选D。

3、【答案】B。解析：《宪法》第四十五条规定，中华人民共和国公民在年老、疾病或者丧失劳动能力的情况下，有从和社会获得物质帮助的权利。发展为公民享受这些权利所需要的社会保险、社会救济和医疗卫生事业。故本题答案为B。

4、【答案】A。解析：《刑法》第十四条规定：“明知自己的`行为会发生危害社会的结果，并且希望或者放任这种结果发生，因而构成犯罪的，是故意犯罪。”本题中，乙没有希望或者放任房屋烧毁的心态，不属于故意，排除B;第十五条规定：“应当预见自己的行为可能发生危害社会的结果，因为疏忽大意而没有预见，或者已经预见而轻信能够避免，以致发生危害社会的结果，是过失犯罪。”乙应当认识到烧木材可能会引起的后果，但是因为疏忽大意没有预见，属于疏忽大意的过失，A正确;D错误;本案例不属于意外事件，排除C。故本题正确答案为A。

5、【答案】D。解析：充足气的自行车内胎在烈日下爆裂，表明的是分子随着温度升高而加速运动，导致空气分子间距增大。D项表述错误。故本题答案选D。

6、【答案】A。解析：幽州在今河北北部及辽宁一带，幽州城就是幽州区域的治所，在的北京。A选项错误;长安，当今西安的古称，历史上个被称为“京”的城市，外国人称之为中华民族的精神故乡。B选项对应正确;元大都，简称大都，其城址位于今北京市市区，北至元大都土城遗址，南至长安街，东西至二环路。C选项正确;南京的别称很多，有金陵、秣陵、建业、建康、白下等。D选项对应正确。故本题答案为A。

A、事物发展的方向和道路 B、事物发展的源泉和动力

C、事物发展的结构和层次 D、事物发展的形式和状态

参考答案及解析

1、【答案】C。解析：“隐形飞机”的目的是让雷达无法侦察到飞机的存在。故本题答案为C。

2、【答案】C。解析：通告是适用于公布社会各有关方面应当遵守或者周知事项的公文。故本题答案选C。

3、【答案】A。解析：基尼系数为意大利经济学家基尼于1922年提出的，定量测定收入分配差异程度。其值在0和1之间。越接近0就表明收入分配越是趋向平等，反之，收入分配越是趋向不平等。按照国际一般标准，0、4以上的基尼系数表示收入差距较大，当基尼系数达到0、6以上时，则表示收入差距很大。因此甲国基尼系数最低，收入分配最平等。

4、【答案】C。解析：党的十六届六中全会明确提出要建设社会主义核心价值体系。社会主义核心价值体系在中国整体社会价值体系中居于核心地位，发挥着主导作用，决定着整个价值体系的基本特征和基本方向。社会主义核心价值体系包括四个方面的基本内容，即马克思主义指导思想、中国特色社会主义共同理想、以爱国主义为核心的民族精神和以改革创新为核心的时代精神、以“八荣八耻”为主要内容的社会主义荣辱观。故选择C。

5、【答案】C。解析：将邓小平理论确立为党的指导思想的是党的十五大，三个代表确立为指导思想的是十六大，科学发展观确立为指导思想的是。因此，本题答案选C。

6、【答案】B。解析：对立统一规律是唯物辩证法的根本规律，在三大规律中处于核心地位，起实质作用。因为它揭示了事物发展的源泉和动力，揭示了事物普遍联系的内容，是贯穿于辩证法其他规律和范畴的主线。故本题答案为B。
