Reading Writing Skills
Reading Skill Scanning for specific information
in reading materials. When you know what
kind of information youre looking for in a
reading textfor example when youre researching
a paper ( or answering comprehension
questions!)scanning the text first can help you
in three ways a) by letting you know whether
the text contains any of the sort of information
youre seeking. b) by giving you an impression
of the authors aims, and c) by giving you an
idea of where in the text youll find the
information thats relevant to you. All three of
these advantages of scanning can make you a more
effective and faster reader.

general observations and supported with a series
of specific inter-related details, making a
reference to the following sample paragraph
From a geological point of view, the modern era
is just a brief mild phase in the middle of one
of the most devastating periods in the history of
the Earth. In the last few million years the
Earth has experienced several Ice Ages, and
theres no reason to expect that theyre over.
Between Ice Ages , there have been periods of
global warming, turning the world into one big
tropical rain forest. At the same time, the
oceans and lakes have periodically changed size,
flooding vast regions and then drying up again.

Intensive Study
Get Ready for Some Wild Weather Per Ola Emily
D'aulaire     1 In March of 1997, Stephen Zebiak
stared at his computer screen in alarm. The
veteran climate researcher saw indications of a
worldwide weather event that, over the years, has
been blamed for droughts and floods, famine,
fires and thousands of deaths. Called El Niño, it
is the most disruptive climatic phenomenon on the
planet.
9
Intensive Study
2 Zebiak and Mark Cane, research scientists at
Columbia University, had developed a computerized
forecast model that correctly predicted El Niño's
occurrences in 1982, 86 and 91, and it had
pointed to a recurrence in 98. But the data
appearing on Zebiaks screen from satellite and
sea-surface monitors across the Pacific were
unmistakable El Niño was already beginning. A
huge pool of warm water larger than the United
States and some 600 feet deep was moving slowly
but surely eastward toward South America.
10
Intensive Study
3 In June the equatorial trade winds reversed
direction from westward to eastward. By
September, waters off Northern California were
roughly 17 degrees warmer than normal. Off the
Washington coast, stunned fishermen caught
tropical fish that seldom stray that far north.
Storms were flooding central Chile, and
heavier-than-normal snowfalls in the Andes
trapped hundreds in the bitter cold. And all of
this only foretold of even more devastating
weather for the fall and winter.
11
Intensive Study
4 El Niño means little boy in Spanish when
capitalized, it refers to the Christ child. This
innocent-sounding name originated in the 19th
century, when Peruvian sailors noticed that every
few years around Christmastime, waters near the
coasts warmed up and the current shifted
southward. But this little boy plays havoc
around the globe.
12
Intensive Study
5 El Niño occurs when weather patterns in the
tropical Pacific shift violently. Normally,
strong westward-blowing trade winds off South
America push surface water toward Asia. Just as
blowing on hot coffee pushes the liquid up
against the opposite side of the cup, the trade
winds pile warm water against the coastlines of
Australia, Indonesia and the Philippines. Above
the warm water, moist air rises, lowering
atmospheric pressure and triggering the tropical
showers that nourish the rain forests of Asia.
Meanwhile high-altitude winds travel back toward
South America. There, the cooled air sinks,
raising atmospheric pressure and suppressing rain
along most of the Pacific coast, making it one of
the driest regions in the world.
13
Intensive Study
6 But with El Niño, the pattern reverses.
Atmospheric pressure in the Western Pacific
rises, setting the stage for drought from
Australia to India. The trade winds decrease, or
in extreme years reverse to blow eastward. As a
result, a huge mass of warm water flows back
toward South America, causing storms from Chile
to California. Meanwhile, over the Pacific,
ten-mile-high storm clouds further heat the
atmosphere, fueling a stronger-than-normal jet
stream, which often splits in two. One branch
moves north, warming the Pacific Northwest,
central Canada and Alaska. Another branch surges
south, producing heavy rains in the U.S. Gulf
States and Southwest.
14
Intensive Study
7 El Niño's vast impact on humans has often been
catastrophic. The El Niño of 1982-83 inflicted
13 billion in damage and claimed some 2,000
lives. In Australia day turned to night when a
dust storm blanketed Melbourne brush fires raged
in its wake. In place of its normal monsoon,
Southern India got dried-up crops and the threat
of mass starvation. At the same time, violent
rainstorms devastated the Western Hemisphere
Perus fishing industry once one of the richest
in the world was wiped out, and seaside towns
were washed into the Pacific.
15
Intensive Study
8 Is there a good side to El Niño? There can be.
Zebiak notes that the number of tropical
hurricanes in the Atlantic is reduced during an
El Niño year. One theory is that winds created by
El Niño shear off the tops of Atlantic
hurricanes, aborting them before they reach full
force. And a team of scientists in Israel who
study tree rings and satellite cloud pictures
concluded that El Niño may bring precious
moisture to the thirsty Middle East. It is
perhaps fitting that El Niño the Christ child
should have a link to the Holy Land, notes
scientist Dan Yakir.
16
Intensive Study
9 This year, scientists around the world are
keeping a sharp eye on El Niño. They know that
the greater the temperature rise in Pacific
waters off South America, the more powerful the
El Niño. And this years waters have heated up
unusually fast. Climate-change researcher Michael
Ghil of UCLA expects the impact to be
substantial. Ants Leetmaa, director of the
National Oceanic and Atmospheric Administration's
Climate Prediction Center in Maryland, agrees
This El Niño is shaping up as one of the most
powerful ever.
17
Intensive Study
10 According to forecasters, hardest hit in this
country will likely be California, where heavy
rains can send houses sliding down muddy slopes
onto washed-out coastal highways. The nations
southern states from California to Florida
can expect cooler and wetter weather than normal
this winter and spring, with extensive storms in
some areas. The Northwest should be warmer and
drier than normal.
18
Intensive Study
11 Wetter-than-normal conditions are expected in
much of South America. The Asian monsoon rains
could fail, resulting in food shortages in India.
In Australia, where El Niño typically means
drought, strict water conservation is already
under way. 12 El Niños effects wont just be
climatic, of course the global economy is sure
to suffer as well. Drought in Brazil and flooding
in Colombia may result in higher prices for
coffee and other crops. And fishing industries
from Ecuador to California are already being
hurt.
19
Intensive Study
13 Clearly, the more accurately scientists can
forecast El Niño, the more people everywhere can
prepare. Insurance companies, farmers, power and
irrigation companies, public-safety agencies and
even tourist boards could benefit from knowing in
advance when El Niño will strike. 14 Reliable
forecasting is still in its infancy, states Mark
Cane. Someday, perhaps, scientists will be able
to predict exactly how El Niño will behave. But
for now, batten down the hatches and get ready
for some wild weather! (985 words)

From a geological point of view, the modern era

In the last few million years the Earth has
experienced several Ice Ages, and theres no

Ages, there have been periods of global warming,
turning the world into one big tropical rain
