Part II  Reading Comprehension    (35 minutes)
Passage One
Questions 21 to 25 are based on the following passage.
Each summer, no matter how pressing my work schedule, I take off one day exclusively

for my son. We call it dad-son day. This year our third stop was the amusement park,

where he discovered that he was tall enough to ride one of the fastest roller

coasters(过山车) in the world. We blasted through face-stretching turns and loops for

ninety seconds. Then, as we stepped off the ride, he shrugged and, in a distressingly

calm voice, remarked that it was not as exciting as other rides he’d been on. As I

listened, I began to sense something seriously out of balance.
Throughout the season, I noticed similar events all around me. Parents seemed hard

pressed to find new thrills for indifferent kids. Surrounded by ever-greater

stimulation, their young faces wore looking disappointed and bored.
Facing their children’s complaints of “nothing to do”. Parents were shelling out

large numbers of dollars for various forms of entertainment. In many cases the money

seemed to do little more than buy transient relief from the terrible moans of their

bored children. This set me pondering the obvious question: “How can it be so hard

for kids to find something to do when there’s never been such a range of stimulating

entertainment available to them?”
Why do children immersed in this much excitement seem starved for more? That was, I

realized, the point. I discovered during my own reckless adolescence that what creates

excitement is not going fast, but going faster. Thrills have less to do with speed

than changes in speed.
I’m concerned about the cumulative effect of years at these levels of feverish

activity. It is no mystery to me why many teenagers appear apathetic (麻木的) and

burned out, with a “been there, done that” air of indifference toward much of life.

As increasing numbers of friends’ children are prescribed medications-stimulants to

deal with inattentiveness at school or anti-depressants to help with the loss of

interest and joy in their lives-l question the role of kids boredom in some of the

diagnoses.
My own work is focused on the chemical imbalances and biological factors related to

behavioral and emotional disorders. These are complex problems. Yet I’ve been

reflecting more and more on how the pace of life and the intensity of stimulation may

be contributing to the rising rates of psychiatric problems among children and

adolescents in our society.
21. The author felt surprised in the amusement park at the face that________.
A) his son was not as thrilled by the roller coaster ride as expected
B) his son blasted through the turns and loops with his face stretched
C) his son appeared distressed but calm while riding the roller coaster
D) his son could keep his balance so well on the fast-moving roller coaster
22. According to the author, children are bored _________.
   A) unless their parents can find new thrills for them
   B) when they don’t have any access to stimulating fun games
   C) when they are left alone at weekends by their working parents
   D) even if they are exposed to more and more kinds of entertainment
23. From his own experience. the author came to the conclusion that children seem to

expect ________.
A) a much wider variety of sports facilities
B) activities that require sophisticated
C) ever-changing thrilling forms of recreation
D) physical exercises that are more challenging
24. In Para. 6 . the author expresses his doubt about the effectiveness of trying to

change children indifference toward much of life by ________.
A) diverting their interest from electronic visual games
B) prescribing medications for their temporary relief
C) creating more stimulating activities for them
D) spending more money on their entertainment
25. In order to alleviate children’s boredom, the author would probably suggest ____

.
A) adjusting the pace of life and intensity of stimulation
B) promoting the practice of dad-son days
C) consulting a specialist in child psychology
D) balancing school work with extracurricular activities
Passage Two
Questions 26 to 30 are based on the following passage.
It used to be that people were proud to work for the same company for the whole of

their working lives. They’d get a gold watch at the end of their productive years and

a dinner featuring speeches by their bosses praising their loyalty/But today’s rich

capitalists have regressed (倒退) to the “survival of the fittest” ideas and their

loyalty extends not to their workers or even to their stockholders but only to

themselves. Instead of giving out gold watches worth a hundred or so dollars for forty

or so years of work, they grab tens and even hundreds of millions of dollars as they

sell for their own profit the company they may have been with for only a few years.
The new rich selfishly act on their own to unfairly grab the wealth that the country

as a whole has produced. The top l percent of the population now has wealth equal to

the whole bottom 95 percent and they want more. Their selfishness is most shamelessly

expressed in downsizing and outsourcing (将产品包给外公司做) because these business

maneuvers don’t act to create new jobs as the founders of new industries used to do,

but only to cut out jobs while keeping the money value of what those jobs produced for

themselves.
To keep the money machine working smoothly the rich have bought all the politicians

from the top down. The president himself is constantly leaving. Washington and the

business of the nation because he is summoned to “fundraising dinners” where fat

cats pay a thousand or so dollars a plate to worm their way into government not

through service but through donations of vast amounts of money. Once on the inside

they have both political parties busily tearing up all the regulations that protect

the rest of us from the greed of the rich.
The middle class used to be loyal to the free enterprise system. In the past, the

people of the middle class mostly thought they’d be rich themselves someday or have a

good shot at becoming rich. But nowadays income is being distributed more and more

unevenly and corporate loyalty is a thing of the past. The middle class may also wake

up to forget its loyalty to the so-called free enterprise system altogether and the

government which governs only the rest of us while letting the corporations do what

they please with our jobs. As things stand. if somebody doesn’t wake up, the middle

class is on a path to being downsized all the way to the bottom of society.
26. It can be inferred form the first paragraph that people used to place a high value

on _________ .
A) job security
B) bosses’ praise
C) corporate loyalty
D) retirement benefits
27. The author is strongly critical of today’s rich capitalists for _________.
A) not giving necessary assistance to laid-off workers
B) maximizing their profits at the expense of workers
C) not setting up long-term goals for their companies
D) rewarding only those who are considered the fittest
28. The immediate consequence of the new capitalists’ practice is ________ .
A) loss of corporate reputation
B) lower pay for the employees
C) a higher rate of unemployment
D) a decline in business transactions
29. The rich try to sway the policy of the government by ________ .
A) occupying important positions in both political parties
B) making monetary contributions to decision-makers
C) pleasing the public with generous donations
D) constantly hosting fundraising dinners
30. What is the author’s purpose in writing this passage?
A) To call on the middle class to remain loyal to the free enterprise system.
B) To warn the government of the shrinking of the American middle class.
C) To persuade the government to change its current economic policies.
D) To urge the middle class to wake up and protect their own interests.#p#副标题#e#
Passage Three
Questions 31 to 35 are based on the following passage
Intel chairman Andy Grove has decided to cut the Gordian knot of controversy

surrounding stem cell research by simply writing a check.
The check, which he pledged last week, could be for as much as $5 million, depending

on how many donors make gifts of between $50,000 and $500,000. which he has promised

to match. It will be made out to the University of California-San Francisco (UCSF).
Thanks in part to such private donations, university research into uses for human stem

cells the cells earliest stages of development that can form any body part-will

continue in California. With private financial support, the state will be less likely

to lose talented scientists who would be tempted to leave the field or even leave the

field or even leave the country as research dependent on federal money slows to a

glacial (极其缓慢的) pace.
Hindered by limits President Bush placed on stem cell research a year ago, scientists

are turning to laboratories that can carry out work without using federal money. This

is awkward for universities. Which must spend extra money building separate labs and

keeping rigorous records proving no federal funds were involved. Grove’s donation, a

first step toward a $20 million target at UCSF. Will ease the burden.
The president’s decision a year ago to allow research on already existing stem cell

lines was portrayed as a reasonable compromise between scientists’ needs for cells to

work with, and concerns that this kind of research cold lead to wholesale creation and

destruction of human embryos (胚胎)。 Cloned infants and a general contempt for human

life.
But Bush’s effort to please both sides ended up pleasing neither. And it certainly

didn’t provide the basis for cutting edge research. Of the 78 existing sxisting stern

cell lines which Bush said are all that science would ever need, only one is in this

country ( at the University of Wisconsin), and only five are ready for distribution to

researchers. All were grown in conjunction with mouse cells, making future therapeutic

(治疗的) uses unlikely.
The Bush administration seems bent on satisfying the small but vocal group of

Americans who oppose stem cell research under any conditions. Fortunately, Grove and

others are more interested in advancing scientific research that could benefit the

large number of Americans who suffer from Parkinson’s disease, nerve injuries, heart

diseases and many other problems.
31.When Andy Grove decided to cut the Gordian knot, he meant to _______.
A) put an end to stem cell research
B) end Intel’s relations with Gordian
C) settle the dispute on stem cell research quickly
D) expel Gordian from stem cell research for good
32. For UCSF to carry on stem cell research, new funds have to come from _______.
A) interested businesses and individuals
B) the United States federal government
C) a foundation set up by the Intel Company
D) executives of leading American companies
33. As a result o the limits Bush placed on stem cell research, American universities

will __________.
A) conduct the research in laboratories overseas
B) abandon the research altogether in the near future
C) have to carry out the research secretly
D) have to raise money to build separate labs
34. We may infer from the passage that future therapeutic uses of stem cells will be

unlikely unless ________.
A) human stem cells are used in the research
B) a lot more private donations can be secured
C) more fcderal money is used for the research
D) talented scientists are involved in the research
35. The reason lying behind President Bush’s placing limits on stem cell research is

that __________.
A) his administration is financially pinched
B) he did not want to offend its opponents
C) it amounts to a contempt for human life
D) it did not promise any therapeutic value

Passage Four
Questions 36 to 40 are based on the following passage.
This looks like the year that hard-pressed tenants in California will get relief-not

just in the marketplace, where rents have eased, but from the state capital

Sacramento.
Two significant tenant reforms stand a good chance of passage. One bill, which will

give more time to tenants being evicted (逐出),will soon be heading to the governor’

s desk. The other, protecting security deposits, faces a vote in the Senate on Monday.
For more than a century, landlords in California have been able to force tenants out

with only 30 days’ notice. That will now double under SB 1403, which got through the

Assembly recently The new protection will apply to renters who have been in an

apartment for at least a year.
Even 60 days in a tight housing market won’t be long enough for some families to find

at apartment near where their kids go to school, But it will be an improvement in

cities like San Jose where renters rights groups charge that unscrupulous (不择手段的)

landlords have kicked ou tenants on short notice to put up rents.
The California Landlords Association argued that landlords shouldn’t have to wait 60

days to get rid of problem tenants. But the bill gained support when a Japanese real

estate investor sent ou 30-day eviction notices to 550 families renting homes in

Sacramento and Santa Rosa. The land lords lobby eventually dropped its opposition and

instead its forces against AB 2330, re garding security deposits.
Sponsored by Assemblywoman Carole Migden of San Francisco, the bill would establish;

procedure and a timetable for tenants to get back security deposits.
Some landlords view security deposits as a free month’s rent, theirs for the taking.

In mos cases, though, there are honest disputes over damages-what constitutes ordinary

wear and tear.
AB 2330 would give a tenant the right to request a walk-through with the landlord and

to make the repairs before moving out; reputable landlords already do this. It would

increase the penalty for failing to return a deposit.
The original bill would have required the landlord to pay interest in the deposit. The

landlords lobby protested that it would involve too much paperwork over too little

money-less than $10 a year on a $1,000 deposit, at current rates. On Wednesday, the

sponsor dropped the interest section to increase the chance of passage.
Even in its amended form, AB 2330 is , like SB 1403 , vitally important for tenants

and should be made state law.
36. We learn form the passage that SB1403 will benefit _______.
A) long-term real estate investors
B) short-term tenants in Sacramento
C) landlords in the State of California
D) tenants renting a house over a year
37. A 60-day notice before eviction may not be early enough for renters because

_______.
A) moving house is something difficult to arrange
B) appropriate housing may not be readily available
C) more time is needed for their kids’ school registration
D) the furnishing of the new house often takes a long time
38. Very often landlords don’t return tenants’ deposits on the pretext that _______.
A) their rent has not been paid in time
B) there has been ordinary wear and tear
C) tenants have done damage to the house
D) the 30-day notice for moving out is over
39. Why did the sponsor of the AB 2330 bill finally give in on the interest section?
A) To put an end to a lengthy argument.
B) To urge landlords to lobby for its passage.
C) To cut down the heavy paperwork for its easy passage.
D) To make it easier for the State Assembly to pass the bill.
40. It can be learned from the passage that ________.
A) both bills are likely to be made state laws
B) neither bill will pass through the Assembly
C) AB 2330 stands a better chance of passage
D) Sacramento and San Jose support SB 1403
