1. 乙醇汽油
Although, recent years have seen substantial reductions in noxious pollutants from indivi
dual motor vehicles, the number of such vehicles has been steadily increasing consequently,
more than 100 cities in the United States still have levels of carbon monoxide, particulate mat
ter, and ozone (generated by photochemical reactions with hydrocarbons from vehicle exhaus
t) that exceed legally established limits. There is a growing realization that the only effective
way to achieve further reductions in vehicle emissions—short of a massive shift away from th
e private automobile—is to replace conventional diesel fuel and gasoline with cleaner-burning
fuels such as compressed natural gas, liquefied petroleum gas, ethanol, or methanol.
All of these alternatives are carbon-based fuels whose molecules are smaller and simpler than
those of gasoline. These molecules burn more cleanly than gasoline, in part because they ha
ve fewer, if and, carbon-carbon bonds, and the hydrocarbons they do emit are less likely to g
enerate ozone. The combustion of larger molecules, which have multiple carbon-carbon bond
s, involves a more complex series of reactions. These reactions increase the probability of inc
omplete combustion and are more likely to release uncombusted and photochemically active
hydrocarbon compounds into the atmosphere. On the other hand, alternative fuels do have d
rawbacks. Compressed natural gas would require that vehicles have a set of heavy fuel tanks
—a serious liability in terms of performance and fuel efficiency—and liquefied petroleum gas f
aces fundamental limits on supply.
Ethanol and methanol, on the other hand, have important advantages over other carbon
-based alternative fuels: they have a higher energy content per volume and would require mi
nimal changes in the existing network for distributing motor fuel. Ethanol is commonly used a
s a gasoline supplement, but it is currently about twice as expensive as methanol, the low cos
t of which is one of its attractive features. Methanol’s most attractive feature, however, is tha
t it can reduce by about 90 percent the vehicle emissions that form ozone, the most serious u
rban air pollutant.
Like any alternative fuel, methanol has its critics. Yet much of the criticism is based on th
e use of “gasoline clone” vehicles that do not incorporate even the simplest design improvem
ents that are made possible with the use of methanol. It is true, for example, that a given vol
ume of methanol provides only about one-half of the energy that gasoline and diesel fuel do;
other things being equal, the fuel tank would have to be somewhat larger and heavier. Howe
ver, since methanol-fueled vehicles could be designed to be much more efficient than “gasoli
ne clone” vehicles fueled with methanol, they would need comparatively less fuel. Vehicles in
corporating only the simplest of the engine improvements that methanol makes feasible woul
d still contribute to an immediate lessening of urban air pollution.

2. 长江水道
Since the 1970s, archaeological sites in China's Yangtze River region have yielded
evidence of sophisticated rice-farming societies that predate signs of rice cultivation elsewhere
in East Asia by a thousand years. Before this evidence was discovered, it had generally been
assumed that rice farming began farther to the south. This scenario was based both on the
geographic range of wild or free-living rice, which was not thought to extend as far north as the
Yangtze, and on archaeological records of very early domestic rice from Southeast Asia and
India (now known to be not so old as first reported). Proponents of the southern-origin theory
point out that early rice-farming societies along the Yangtze were already highly developed and
that evidence for the first stage of rice cultivation is missing. They argue that the first
hunter-gatherers to develop rice agriculture must have done so in this southern zone, within
the apparent present-day geographic range of wild rice.
Yet while most stands of wild rice reported in a 1984 survey were concentrated to the
south of the Yangtze drainage, two northern outlier populations were also discovered in
provinces along the middle and lower Yangtze, evidence that the Yangtze wetlands may fall
within both the present-day and the historical geographic ranges of rice's wild ancestor.
2.1. Which of the following, if true, would most clearly undermine the conclusion that the
author makes based on the 1984 survey?
A. Areas south of the Yangtze basin currently have less wild-rice habitat than they once did.

B. Surveys since 1984 have shown wild rice populations along the upper Yangtze as well as
along the middle and lower Yangtze.
C. The populations of wild rice along the Yangtze represent strains of wild rice that migrated to
the north relatively recently.
D. Early rice-farming societies along the Yangtze were not as highly developed as
archaeologists once thought.
E. In East Asia, the historical geographic range of wild rice was more extensive than the
present-day geographic range is.
2.2. Based on the passage, skeptics of the idea that rice cultivation began in the Yangtze River
region can point to which of the following for support?
A. Lack of evidence supporting the existence of rice-farming societies along the Yangtze at an
early date
B. Lack of evidence regarding the initial stages of rice cultivation in the Yangtze region
C. Recent discoveries pertaining to the historical geographic range of rice's wild ancestor
D. New information regarding the dates of very early domestic rice from Southeast Asia
E. New theories pertaining to how hunter-gatherers first developed rice agriculture in East Asia
2. 3. Which of the following can be inferred from the passage about the “southern-origin
theory”?
A. The theory is based on an unconventional understanding of how hunter-gatherers first
developed rice agriculture.
B. The theory fails to take into account the apparent fact that evidence for the first stage of rice
cultivation in the north is missing.
C. The theory was developed primarily in response to a 1984 survey of wild rice's geographic
range.
D. Reassessment of the dates of some archaeological evidence has undermined support for the
theory.
E. Evidence of sophisticated rice-farming societies in the Yangtze region provides support for
the theory.

3. The Color Purple
The publication of The Color Purple transformed Alice Walker from an indu- bitably serious
black writer whose fiction belonged to a tradition of gritty, if occasionally "magical," realism into
a popular novelist, with all the perquisites and drawbacks attendant on that position. Unlike
either The Third Life of Grange Copland (1970) or Meridian (1976), The Color Purple gained
imme- diate and widespread public acceptance, winning both the Pulitzer Prize and the
American Book Award for 1982-83. At the same time, however, it generated immediate and
widespread critical unease over what appeared to be manifest flaws in its composition. Robert
Towers, writing in the New York Review of Books, concluded that on the evidence of The Color
Purple "Alice Walker still has a lot to learn about plotting and structuring what is clearly

intended to be a realistic novel." His opinion was shared by many reviewers, who pointed out
variously that in the last third of the book the narrator-protagonist Celie and her friends are
propelled toward a fairytale happy ending with more velocity than credibility; that the letters
from Nettie, with their disconcertingly literate depictions of life in an African village, intrude into
the middle of the main action with little apparent motivation or warrant; and that the device of
the letters to God is especially unrealistic inasmuch as it foregoes the concretizing details that
traditionally have given the epistolatory form its peculiar verisimilitude: the secret writing-place,
the cache, the ruses to enable posting letters, and especially the letters received in return.
4. 英国女演员 Actress的地位:
In the past, only men could become actors in some societies. In the ancient Greece and
Rome and the medieval world, it was considered disgraceful for a woman to go on the stage,
and this belief persisted until the 17th century, when in Venice it was broken. In the time of
William Shakespeare, women's roles were generally played by men or boys.
When an eighteen-year Puritan prohibition of drama was lifted after the English
Restoration of 1660, women began to appear on stage in England. Margaret Hughes is credited
by some as the first professional actress on the English stage. This prohibition ended during the
reign of Charles II in part due to the fact that he enjoyed watching actresses on stage. The first
occurrence of the term actress was in 1700 according to the OED and is ascribed to Dryden.
In Japan, men (onnagata) took over the female roles in kabuki theatre when women were
banned from performing on stage during the Edo period. This convention has continued to the
present. However, some forms of Chinese drama have women playing all the roles.
In modern times, women sometimes play the roles of prepubescent boys. The stage role
of Peter Pan, for example, is traditionally played by a woman, as are most principal boys in
Britishpantomime. Opera has several "breeches roles" traditionally sung by women, usually
mezzo-sopranos. Examples are Hansel in Hänsel und Gretel, Cherubino in The Marriage of
Figaro and Octavian in Der Rosenkavalier.
Women in male roles are uncommon in film with the notable exceptions of the films The
Year of Living Dangerously and I'm Not There. In the former film Linda Hunt played the pivotal
role of Billy Kwan, for which she received the Academy Award for Best Supporting Actress. In
the latter film Cate Blanchett portrayed Jude Quinn, a representation of Bob Dylan in the sixties,
for which she was nominated for the Academy Award for Best Supporting Actress. Women
playing men in live theatre is particularly common in presentations of older plays, such as those
of Shakespeare, that have large numbers of male characters in roles where the gender no
longer matters in modern times.
Having an actor dress as the opposite sex for comic effect is also a long-standing tradition
in comic theatre and film. Most of Shakespeare's comedies include instances of overt
cross-dressing, such as Francis Flute in A Midsummer Night's Dream. The movie A Funny Thing

Happened on the Way to the Forum stars Jack Gilford dressing as a young bride. Tony
Curtisand Jack Lemmon famously posed as women to escape gangsters in the Billy Wilder film
Some Like It Hot. Cross-dressing for comic effect was a frequently used device in most of the
thirty Carry On films. Dustin Hoffman and Robin Williams have each appeared in a hit comedy
film (Tootsie and Mrs. Doubtfire, respectively) in which they played most scenes dressed as a
woman.
Occasionally, the issue is further complicated, for example, by a woman playing a woman
acting as a man pretending to be a woman, like Julie Andrews in Victor/Victoria, or Gwyneth
Paltrow in Shakespeare in Love. In It's Pat: The Movie, film watchers never learn the gender of
the androgynous main characters Pat and Chris (played by Julia Sweeney and Dave Foley).
A few roles in modern films, plays and musicals are played by a member of the opposite sex
(rather than a character cross-dressing), such as the character Edna Turnblad in
Hairspray—played by Divine in the original film, Harvey Fierstein in the Broadway musical, and
John Travolta in the 2007 movie musical. Linda Hunt won an Academy Award for Best
Supporting Actress for playing Billy Kwan in T
