A meager（不足的）diet may give you health and long life, but it's not much fun一and it might not even be necessary. We may be able to hang on to most of that youthful（有青春活力的）vigor （精力）even if we don't start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation（恢复活力，返老还童） won't reverse other damage caused by time for the mouse,but could help its liver metabolize（使进入新陈代谢过程）drugs or get rid of toxins.
Spindler's team fed three mice a normal diet for their whole lives,and fed another three on half-rations.Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old一equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers,and found that 46 changed with age in the normally fed mice.The changes were associated with things like inflammation and free radical production一probably bad news for mouse health.In the mice that had dieted all their lives,27 of those 46 genes continued to behave like young genes.But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes.
"This is the first indication that these effects kick in pretty quickly",says Huber Warner from the National Institute on Aging near Washington D.C.
No one yet knows if calorie restriction works in people as it does in mice,but Spindler is hopeful."There's attracting and tempting evidence out there that it will work,"he says.
If it does work in people,there might be good reasons for rejuvenating the liver. As we get older,our bodies are less efficient at metabolizing drugs,for example.A brief period of time of dieting,says Spindler,could be enough to make sure a. drug is effective.
But Spindler isn't sure the trade-off is worth it."The mice get less disease,they live longer,but they're hungry,"he says."Even seeing what a diet does,it's still hard to go to a restaurant and say:I can only eat half of that."
Spindler hopes we soon won't need to diet at all. His company,Lifespan Genetics in California, is looking for drugs that have the effects of calorie restriction.
According to the author,which of the following most interested the researchers?
A:The mice that started dieting in old age
B:27 of those 46 old genes that continued to behave like young genes
C:Calorie restriction that works in people
D:Dieting that makes sure a drug is effective

Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate.A black
hole in the universe is not a solid object,like a planet,but it is shaped like a sphere（球体）.
Astronomers（天文学家）think that at the center of a black hole there is a single point in
space with infinite（无限的）density（稠密）.This single point is called a singularity（奇点）.
If the singularity theory is correct,it means that when a massive star collapses,all the
material in it disappears into the singularity.The center of a black hole would not really be a
hole at all,but an infinitely dense point.Anything that crosses the black hole is pulled in by
its great gravity.
Although black holes do exist,they are difficult to observe.These are the reasons.
No light or anything else comes out of black holes.As a result,they are invisible to
a telescope.
In astronomical terms,black holes are truly tiny.For example,a black hole formed
by the collapse of a giant star would have an event horizon（视界）only 18 miles across.
The nearest black holes would be dozens of light years away from Earth.One light
year is about 6 trillion（万亿）miles. Even the most powerlul telescopes could not pick out
an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist.There
are still answers to be found,however,so black holes remain one of the mysteries of the
universe.
The center of a black hole is empty.
A:Right
B:Wrong
C:Not mentioned

and become financially independent,it becomes possible for them to maintain a one-person
household.________(3)However,people who do get married are marrying at a later
age and divorcing more often.
The number one reason given by most people for living alone is that they simply enjoy
doing what they want when they want to do it."Living alone is a luxury,"says Nina Hagiwara,

The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
and to move from place to place.In fact,the human body does its work so well that most people don't think
about it very much-until they get sick.
The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
How can you stop these tiny invaders from making you sick?Your skin is the first defense against
germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
body through small cuts in the skin or through the mouth,eyes,and nose.
Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
That way you will not get the same illness twice.
You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune systerm
strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
antibodies attack it.
Viruses can only live inside people or animals.

Earthquake
How does an earthquake start?
What makes an earthquake happen? The rock of the earth's crust（地壳）may have a
"fault",a kind of break in the surface.The blocks which make up the earth move,and
sometimes this may cause the sides of the fault to move up and down or lengthways（纵向
地）against each other. When one piece of rock starts to rub on another with great force,a
lot of energy is used. This energy is changed into vibrations（振动）and it is these vibrations
that we feel as an earthquake.The vibrations can travel thousands of kilometers and so an
earthquake in Turkey may be felt in Greece.
What to do during an earthquake?
At school
As soon as the earthquake starts,students should get under the desks immediately and
wait until the teacher tells them it is safe to come out.The teacher should,at the same
time, go immediately to the teacher's desk, get underneath（在……下面）it and stay there
till the danger is over. Students must not argue with the teacher or question instructions.
As soon as the tremors（震动）stop, all students should walk towards the exit and go
straight to the school playground or any open space such as a square or a park.They must
wait there until the teacher tells them it is safe to go.
At home
If you are at home when the earthquake occurs,get immediately under the table in the
living room or kitchen.Choose the biggest and strongest table you can find.You must not
go anywhere near the window and don't go out onto the balcony（阳台）.Once the tremors
have stopped,you can come out from under the table but you must leave the building
straight away.You should walk down the stairs and should not use the lift一there may be a
power cut as a result of the earthquake and you could find yourself trapped inside the lift for
hours.
In the street
If you are in the street when the earthquake takes place,do not stand near buildings,
fences or walls一move away as quickly as possible and try to find a large open space to wait
in.Standing under trees could also be dangerous.
If you are in the street when an earthquake occurs,stay in a large open space.

US to Start $3.2 Billion Child Health Study in January
A study that will cost$3.2 billion and last more than two decades to track the health of 100,000 US children from before birth to age 21 will be launched in January,US health officials said on Friday.
Officials from the US government's National Institutes of Health said they hope the study,to be conducted at 105 locations throughout the United States,can help identify early-life influences that affect later development,with the goal of learning new ways to treat or prevent illness.
The study will examine hereditary（遗传的）and environmental factors such as exposure to certain chemicals that affect health.
Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air,water,dust and materials used to construct their residences,the NIH said.
Officials said more than $200 million has been spent already and the study is projected to cost$3.2 billion.
"We anticipate that in the long term（从长远来说）,what we learn from the study will result in a significant savings in the nation's health care costs,"Dr. Duane Alexander,who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development,told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up（签订协议）pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth（早产）,which has become more common in recent years,according to Dr. Peter Scheidt of the NIH,who heads the study.
The people taking part will be from rural,urban and suburban areas,from all income and educational levels and from all racial groups,the NIH said.
It is expected that through the study the nation's health care costs______.
A:will be lowered in the long run
B:will be significantly increased
C:will be more than $200 million
D:will reach $3.2 billion

Sprained（扭伤）Ankle
One of the most common injuries teenagers and adults experience is a sprained ankle.A sprain occurs
when the ligaments（韧带）of a joint are twisted（扭伤）and possibly torn. Ligaments are bands of fibers that
hold the bones of a joint in position.A sprain can occur from a sudden twisting at the joint,or a stretching or
tearing of the fibers of the ligaments. The injured area usually swells（肿胀）and becomes black and blue.
Stepping off the sidewalk at the wrong angle or having one foot land in a hole while walking or running can
leave you rolling on the ground in pain with an ankle on fire!If you cannot walk without experiencing intense
pain,you must seek medical help.If the pain is manageable,and you can walk,here are three words to help
you remember how to treat yourself:
●Elevate（抬高）
●Cool
●Bandage（打绷带）
As soon as there is injury to that ligament,there will be a certain amount of bleeding under the skin.
Once the blood pools around the damaged blood vessels,swelling occurs.The pressure from the swelling
results in additional stress and tenderness to the region.In order to reduce the degree of swelling,lie down as
soon as possible and keep the ankle elevated so that it is actually higher than your heart.Next,to reduce
blood distribution and keep bleeding（流血）to a minimum, apply a cold pack. After 20 minutes, take the
pack off,wait half an hour and then reapply.This can be done several times a day for a total of three
days.
Never leave a cold pack on for more than 20 minutes at a time.Reducing the temperature in that area for
an extended period of time signals the body to increase blood flow to raise the body temperature!Therefore,
one accidentally triggers（引起）more blood distribution to the affected area by leaving a cold pack on for too
long!Finally,bandage the ankle.Be careful not to wind it too tightly;doing so can restrict blood flow and
cause harm to the entire foot.
A sprain is caused by________.
A:blood vessels being hurt in the foot
B:constantly changing body temperature
C:ligament fibers of a joint being twisted
D:elevating one's ankle

The Forbidden Apple
New York used to be the city that never sleeps. These days it's the city that never smokes,drinks or does anything naughty(at least,not in public).The Big Apple is quickly turning into the Forbidden Apple.
If you wanted a glass of wine with your picnic in Central Park,could you have one?No chance. Drinking alcohol in public isn't allowed. If you decided to feed the birds with the last crumbs（碎屑）of your sandwich, you could be arrested. It's illegal. If you went to a bar for a drink and a cigarette,that would be OK,wouldn't it?Er…no.You can't smoke in public in New York City.
What's going on?Why is the city that used to be so open-minded becoming like this?
The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want,when they want.
The press are shocked. Even the New York police have joined the argument. They re- cently spent$100,000 ona“Don't blame the cop”campaign. One New York police officer said,”We raise money for the city by giving people fines for breaking some very stupid laws. It's all about money.”
The result is lot of fines for minor offences. Yoav Kashida,and Israeli tourist,fell asleep on the subway. When he woke up,two police officers fined him because he had fallen asleep on two seats(you mustn't use two seats in the subway).Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway.
The angry editor of Vanity Fair magazine,Graydon Carter,says.”Under New York City law it is acceptable to keep a gun in your place of work,but not an empty ashtray.”He should know. The police came to his office and took away his ashtray（烟灰缸）.
But not all of New York's inhabitants are complaining. Marcia Dugarry,72,said,”The city has changed for the better. If more cities had these laws,America would be a better place to live.”Nixon Patotkis,38,a barman,said,”I like the new laws. If people smoked in here, we'd go home smelling of cigarettes.”
Recent figures show that New York now has fewer crimes per 100,000 people than 193 other US cities.And it's true一It's safer,cleaner and more healthy than before. But let'sbe honest一who goes to New York for its clean streets?
It's now illegal to smoke or drink alcohol anywhere in New York.
A: Right
B: Wrong
C: Not mentioned

Old Man Myths and Realities
1 When does a middle-aged man become an old man?Officially,of course,it's when we
reach retirement age. But, as we all know, this is a fairly blunt（生硬的）method of
decision making. As life expectancy（预期寿命）increases, retirement planning needs to
be changed .This is because being an old man today is very different from what it was a
generation or so ago.
2 Sixty-five is the new middle-aged man. These days people are talking about the young-
old,that is ages 70-75,and those over 75 as the old-old. The young-old frequently
continue in good health and maintain strong links with friends and family.The old-old have a
much higher chance of poor health and social isolation.
3 Although men are living longer,there are still more old women than old men.This fact
alone should arouse interest as to why.Relatively little is actually known about why this is
the case or about the experiences of the old man .Sure,we are aware that the old man
experiences anxiety,financial problems,loneliness,etc.,but that's really about all we
know.
4 It is usually believed that the old man often complains about their health.In fact,most
rate their health as good even though most are diagnosed with at least one chronic illness.
The physical health of the old man is strongly affected by their health behavior when they
were younger.
Paragraph 4__________
A:New definitions of the old man
B:Changing concept of the old man
C:Health of the old man
D:Happy old man and sad old man
E:Limited knowledge of the old man's experiences
F:Contempt for the old man
