U.S.Eats Too Much Salt
People in the United States consume more than twice the recommended amount of salt,raising their risk for high blood pressure,heart attacks and strokes,government health experts said on Thursday.
They found nearly 70 percent of U.S.adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day,yet most consume close to 3,500 mg per day.
“It's important for people to eat less salt.People who adopt a heart-healthy eating pattern that includes a diet low in sodium and rich in potassium and calcium can improve their blood pressure,”Dr.Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement.
"People need to know their recommended daily sodium limit and take action to reduce sodium intake,"Labarthe said.
The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40-which are considered highrisk groups.
Yet studies show most people in the United States eat 3,436 mg of sodium per day,according to a 2005-2006 CDC estimate.
Most of the sodium eaten comes from packaged,processed and restaurant foods.The CDC said it will join other agencies in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply.
Nationwide,16 million men and women have heart disease and 5.8 million are estimated to have had a stroke.Cutting salt consumption can reduce these risks,the CDC said.

How much salt do most American adults eat per day?
A:No more than 1,500 mg.
B:Closer to 3,500 mg.
C:Less than 3,436 mg.
D:Closer to 1,500 mg.

Passage 2
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to
eat. some research has shown that perhaps eighty percent of all human illness are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more prone to contract certain illness because of the food that is characteristic in these cultures.
That food related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in
our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.
The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the
Food and Drug Administration （FDA） has tried repeatedly to control these procedures, the practices continue.

Why do farmers give drugs to their animals?

A. To speed up the growth of animals.
B. To make the animals fatter.
C. To make the animals' meat fit to eat.
D. To make the animals' meat rich in nutrients.

More Than 8 Hours Sleep Too Much of a Good Thing
1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.
3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside, more than 8 hours a night.He added that“it might be a good idea”for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.
4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
6 Kridke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.

Long sleepers are reported to be more likely to______.
A: fall asleep again
B: become more energetic the following day
C: sleep less than 7 hours
D: confirm those serious consequences
E: suffer sleep problems
F: sleen more than 8 houlrs

Eating Meat一Less or More?



Every second in the United States alone,mnore than 250 animals are slaughtered for food,adding up to

more than 8 billion animals each year. Reducing the amount of meat in one's diet is nutritionally,environ-

mentally,and ethically beneficial.

People who eat meat usually have weaker immune systems compared to those of vegetarians.Meat has

been directly linked to diabetes,obesity,arthritis,and many other illnesses.Furthermore,meat-eaters are

at a higher risk for diseases,including cancer,and they are more likely to die from these diseases.Critics

say that a meatless diet does not provide enough nutrients,especially protein and iron.Actually,according

to A Teen's Guide to Going Vegetarian,by Judy Krizmanic,protein is found in almost every food,and iron

appears in many vegetables.Getting enough nutrients in a meat-reduced diet should not lie difficult.A 1988

study found that some of the highest pesticide residues appear in meat and eggs.Diets including more fruits

and vegetables will only make people healthier.

Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the opposite

is true.More than 80% of the corn and 95%of the oats grown in the U.S.are fed to livestock.The world's

cattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire hu-

man population.One half of the water used in the Unites States also goes to livestock;250 gallons of water

produces only 1 lb.（磅）of beef. If people eat less meat and more plants,the amount of available ftod will

increase。

Many people become vegetarians I)ecause they feel that eating animals is unethical.90%of these ani-

mals are raised in confinement.Chickenls arid other birds have only about half a square foot of space each,

and since they are raised so close together,a lot of blade is used to cut off their beaks to prevent them from

pecking each other to death.Likewise,pigs that are repressed will bite each other's tails,so both their

teeth and tails are removed as soon as they are born.

Eating animals is hazardous in numerous ways.Even a slight reduction in meat intake is better than

nothing at all.Consuming less meat is beneficial to the health of animals,the health of people,and to the

health of the world.

A:Some of the highest pesticide residues appear in meat and eggs.
B:A meatless diet does not provide enough nutrients.
C:Protein can be found in almost every food.

Eating Meat一Less or More?



Every second in the United States alone,mnore than 250 animals are slaughtered for food,adding up to

more than 8 billion animals each year. Reducing the amount of meat in one's diet is nutritionally,environ-

mentally,and ethically beneficial.

People who eat meat usually have weaker immune systems compared to those of vegetarians.Meat has

been directly linked to diabetes,obesity,arthritis,and many other illnesses.Furthermore,meat-eaters are

at a higher risk for diseases,including cancer,and they are more likely to die from these diseases.Critics

say that a meatless diet does not provide enough nutrients,especially protein and iron.Actually,according

to A Teen's Guide to Going Vegetarian,by Judy Krizmanic,protein is found in almost every food,and iron

appears in many vegetables.Getting enough nutrients in a meat-reduced diet should not lie difficult.A 1988

study found that some of the highest pesticide residues appear in meat and eggs.Diets including more fruits

and vegetables will only make people healthier.

Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the opposite

is true.More than 80% of the corn and 95%of the oats grown in the U.S.are fed to livestock.The world's

cattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire hu-

man population.One half of the water used in the Unites States also goes to livestock;250 gallons of water

produces only 1 lb.（磅）of beef. If people eat less meat and more plants,the amount of available ftod will

increase。

Many people become vegetarians I)ecause they feel that eating animals is unethical.90%of these ani-

mals are raised in confinement.Chickenls arid other birds have only about half a square foot of space each,

and since they are raised so close together,a lot of blade is used to cut off their beaks to prevent them from

pecking each other to death.Likewise,pigs that are repressed will bite each other's tails,so both their

teeth and tails are removed as soon as they are born.

Eating animals is hazardous in numerous ways.Even a slight reduction in meat intake is better than

nothing at all.Consuming less meat is beneficial to the health of animals,the health of people,and to the

health of the world.

What is the attitude the author has toward eating meat?
A:Positive.
B:Negative.
C:Indifferent.
D:None of the above.

Eat More, Weigh Less, Live Longer

Clever genetic detective work may have found out the reason why a near-starvation diet
prolonas the life of many animals.
Ronald Kahn at Harvard Medical School in Boston,U.S.,and his colleagues nave
been able to extend the lifespan（寿命）of mice by 18 per cent by blocking the rodent's(啮
齿动物）increase of fat in specific cells.This suggests that thinness一and not necessarily
diet一Iromotes lonq life in"calorie（热量卡）restricted" animals.
"It's very cool work",says aging researche:Cynthia Kenyon of the University ot
California, San Francisc."These mice eat all they want, lose weight and live longer.It's
like heaven."
Calorie restriction dramatically extends the lifespan of organisms as different as worms
and rodents.Whether this works in humans is still unknown,partly because few people are
willina to submit to such a strict diet.
But many researchers hope they will be able to trigger the same effect with a drug once
they understand how less food leads to a longer life.One theory is that eating less reduces
the increase of harmful things that can damage cells.But Kahn's team wondered whether
the animals simply benefit by becoming thin.
To find out, they used biology tricks to disrupt the insulin（胰岛素）receptor (受体)
gene in lab mice一but only in their fat cells."Since insulin is needed to help fat cells store
fat ,these animals were protected against becoming fat,"explains Kahn.
This slight genetic change in a single tissue had dramatic effects.By three months of
age.Kahn's modified mice had up to 70 per cent less body fat than normal control mice,
despite the fact that they ate 55 per cent more food per gram of body weight.
In addition ,their lifespan increased.The average control mouse lived 753 days,while
the thin rodents averaged a lifespan of 887 days.After three years,all the control mice had
died.but one-quarter of the modified rodents were still alive.
"That they ciet these effects by just manipulating the fat cells is controversial,"says
Leonard Guarente of the Massachusetts Institute of Technology,who studies calorie
restriction and aging.
But Guarente says Kahn has yet to prove that the same effect is responsible for
increased lifespan in calorie-restricted animals."It might be the same effect or there might
be two routes to long life,"he points out,"and that would be very interesting."

What can be inferred from the passage about the route to long life?
A:It remains to be studied.
B:It has already been discovered.
C:Eating more leads to long life.
D:Eating less leads to long life.

More Than 8 Hours Sleep Too Much of a Good Thing

Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.
Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.
These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night's rest may not need to set aside more than 8 hours a night. He added that it might be a good idea for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.
Previous studies have shown the potential dangers of chronic shortages of sleep,for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.
For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionnaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.
Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours.In an interview,Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed."It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake,"he said.

One survey showed that people who habitually______each night have a higher risk of dying.
A:fall asleep again
B:become more energetic the following day
C:sleep less than 7 hours
D:confirm those serious consequences
E:suffer sleep problems
F: sleep more than 8 hours
