living building in South Bronx, one of the city"s poorest areas. Two-thirds of the people living there are
formerly (以前) homeless people, whose rent is paid by the government. The rest are low-income families.
The boiler room has special equipment, which produces energy for electricity and heat. It reuses heat that
would otherwise be lost to the air, reducing carbon emissions (碳排放) while also cutting costs.
Fox Point is operated by Palladia, a group that specializes in providing housing and services to needy,
people. Palladia received support from Enterprise Community Partners (ECP), which helps build affordable
housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (环境方面) clever and affordable homes
which are called, the Green Communities Standards. These standards include water keeping, energy saving
and the use of environmentally friendly building materials. Meeting the standards increases housing
construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a
window to get most daylight can help save energy.
Michael Bloomberg, New York"s mayor, plans to create 165,000 affordable housing units for 500,000
New Yorkers. Almost 80% of New York City"s greenhouse-gas emissions come from buildings, and 40%
of those are caused, by housing. So he recently announced that the city"s Department of Housing and
Preservation and Development (DHPD), whose duty is to develop and keep the city"s supply of affordable
housing, will require all its new projects to follow ECP"s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York"s DHPD
is the largest city developer of affordable housing in the country.
B. To suggest that affordable housing is possible in all areas.
C. To show how the environment-friendly building works.
D. To compare old and new boiler rooms.
B. Costing less in construction.
C. Less air to be lost in hot days.
D. Better prices for homeless people.
B. people"s daily life causes many carbon emissions in New York City
C. a great number of people in New York City don"t have houses to live in
D. some other cities have developed more affordable housing than New York City
B. To prove that some standards are needed for affordable housing.
C. To ask society to help homeless people and low-income families.
D. To introduce healthy, environmentally clever-and affordable housing.

out of every 100 Americans are over 65. The aging of the population will affect American society in many
ways: education, medicine, and business. Quietly, the growing of America has made it a very different society,
one in which people have a quite different idea of what kind of behavior is suitable at various ages.
A person"s age no longer tells you anything about his or her social position, marriage or health. There"s no
longer a particular year in which one goes to school or goes to work or gets married or starts a family. The
social clock that kept us on time and told us when to go to school, get a job, or stop working isn"t as strong
as it used to be. It doesn"t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother,
or a 70-year-old man who has become a father for the first time. Public ideas are changing.
Many people say, "I am much younger than my mother or my father was at my age." No one says, "Act
your age" any more. We"ve stopped looking with surprise at older people who act in youthful ways.

X-rays can show a lot. CAT scans can show even more. They can give three-dimensional (三维) view of
body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography (层面X线照相术). It is a special
X-ray machine that gets a 360 - degree picture of a small area of a patient"s body.
Doctors use X-rays to study and examine diseases and injuries within the body. X-rays can find foreign
objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids
are added to the organs to be X-rayed.
A CAT scanner, however, uses a beam (光束) of X-rays to give a cross-sectional view of a particular
part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many
different angles (角度). A computer analyzes (分析) the information from each angle and produces a clear
cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections,
taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT
scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the
action" giving clear pictures of what appear only mistily (模糊) to the eye. And because of the 360-degree
pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery
or autopsy (examining a dead body).
B. checking body organs
C. getting a 360-degree picture of a small area of a patient"s body
D. examining the CAT
B. many pictures can be taken at the same time
C. the information about the scanned patient is not highly valued
D. some pictures of the scanned parts of the body are developed for further examinations in the future
B. Three-dimensional View
C. Fast - moving Camera
D. CAT Scan
global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures
on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level
increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other
parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around
the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much
of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair
itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face
the full impact of global warming. This means an increase in average air temperatures of around 3OC and a
reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors
Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean
waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice
sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western
Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too
late. "Everything is connected-Antarctica may be a long way away but it is an important part of the Earth"s
system," said Johnson. "It contains 90% of the world"s ice, 70% of the world"s fresh water and that is enough,
if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don"t expect the ice to entirely disappear, but predict that, because
of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.
B. approximately
C. contradictorily
D. apparently
B. It is making much of the continent colder.
C. It is making the effects of global warming in the region worse.
D. It is reducing the amount of water in Antarctica.
B. Warming sea water temperature.
C. Water pollution.
D. Growing ice sheets.
B. The average temperature has increased by 3OC in recent decades.
C. Antarctica contains most of the world"s fresh water.
D. Ten percent of Antarctica"s ice has already been lost.
B. Antarctica melting away
C. Action plan to save Antarctica
D. Let"s save the ozone layer
will affect more than one hundred million people worldwide by the year twenty fifty. That would be four
times the current (现在的) number. Researchers and doctors have been studying Alzheimer"s patients for
a century. Yet the cause and cure for the mental (智力的) sickness are still unknown. However, some
researchers have made important steps towards understanding it.
Several early signs of the disease involve (涉及) memory and thought processes. At first, patients have
trouble remembering little things. Later, they have trouble remembering more important things, such as the
names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer"s disease.
The tests look for proteins (蛋白质) in brain and spinal cord fluid (脊髓). The proteins appear to be found
only in people with the disease. The protein tests correctly identify (确定) the presence of the disease in
about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer"s risk has been developed. Researchers found
that trouble with the sense of smell can be one of the first signs of Alzheimer"s disease. Using this information,
they developed a test in which people were asked to identify twelve familiar smells. These smells included
cinnamon (桂皮), black pepper, chocolate, paint thinner (涂料稀释剂), and smoke.
The study continued for five years. During this period, the same people were asked to take several tests
measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of
the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person"s chances of developing Alzheimer"s disease
in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop
Alzheimer"s disease. Those who read a newspaper, or play chess or word games are about three times less
likely to develop the condition.
Researchers say they still do not know what causes Alzheimer"s disease. But they say these findings might
help prevent the disease in the future.
B. Some physical tests about Alzheimer"s disease.
C. The research about Alzheimer"s disease.
D. The patients of Alzheimer"s disease.
B. 25 million
C. 400 million
D. 20million
B. Proteins exist in the brain.
C. Trouble with the sense of smell.
D. Less use of the brain.
B. Alzheimer"s patients.
C. The cause and cure.
D. The research.
B. the people who often use their brains will not get Alzheimer"s disease
C. researchers and doctors have found ways to cure Alzheimer"s disease
D. the people who have the trouble with the sense of smell will certainly suffer from Alzheimer"s disease
they give him shade, and they help to prevent droughts (干旱) and floods.
Unfortunately, in many parts of the world man has not realized that the third of these services is the most
important. In his eagerness (渴望) to draw quick profit from the trees, he has cut them down in large numbers,
only to find that without them he has lost the best friends he had.
Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to
gain itself an empire (帝国). It gained the empire but, without its trees, its soil became hard and poor. When
the empire fell to pieces, the country found itself faced by floods and starvation.
Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to
persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by
making charcoal (木炭) or selling wood to the townsman (城市居民). He is usually too lazy or too careless
to plant and look after trees. So unless the government has a good system of control, or can educate the people,
the forests will slowly disappear.
This does not only mean that the villager"s sons and grandsons have fewer trees. The results are even more
serious. For where there are trees their roots break the soil up-allowing the rain to sink in and also hold the soil,
thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The
rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich
topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.
B. tell people the function of tree roots
C. warn that man mustn"t destroy forests any more
D. explain how trees help to prevent droughts and floods
B. Preventing droughts and floods.
C. Providing charcoal (木炭).
D. Offering wood to human.
B. people shouldn"t draw benefit from the trees
C. government must realize the serious results
D. unless trees are never cut down
B. necessary but difficult
C. impossible and unimportant
D. difficult and impossible
B. where there are many trees, there are more floods
C. where there are no trees, the land might become desert slowly
D. floods will make the land become desert
