A small piece of fish each day may keep the heart doctor away．That's the finding of a scientific study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce（盎司）of salt water fish per day than those who never ate fish.
The Dutch research is one of three human studies that hold the belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year．But researchers previously have noticed that the incidence （发生率） of heart disease is lower in cultures that consume more fish than Americans do．There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.

       At the start of the study, the average fish consumption was about two-thirds of an ounce each day with more men eating thin fish than fatty fish.
During the next two decades, 78 of the men died from heart disease．The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos．This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol （胆固醇） levels.
64．Which of the following is NOT true according to the passage?
A．The Dutch research has proved that eating fish can help to prevent heart disease.
B．Heart doctors won't call at your house so long as you keep eating fish each day.
C．Among all the diseases heart disease is the most dangerous in America.
D．There is a low incidence of heart disease in Japan and Greenland.
65．The underlined phrase "this relationship" refers to the connection between ______and the incidence of heart disease.
A．regular fish-eating              B．the amount of fish eaten
C．the kind of fish eaten             D．people of different regions
66．The passage is mainly about ______.
A．the high incidence of heart disease
B．the great changes in people's diet
C．the fish consumption in some countries
D．the effect of fish eating on people 's health
67．How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?
A．152,000．    B．110,000．          C．275,000．          D．550,000.

Most people think the first pies were made by early Romans. They may have learned about pie making from the Greeks. These pies were sometimes made in"reeds (芦苇叶)", which were used for the purpose of holding the filling (馅 ), and were not eaten.
The Romans spread the word about pies around Europe and the word"pie"became a popular word in the 14th century. The first pie recipe (食谱) was also published by the Romans.
Pies first appeared in England as early as the twelfth century. The early pies were mostly meat pies. There was actually more crust(皮)than filling. Often these pies were made from fowl ( 家禽) and the fowl's legs were left to hang over the side of the dish and used as handles. Fruit pies were probably first made in the 1500s. It is said that Queen Elizabeth I made the first cherry pie.
Pie came to America with the first English settlers. The early settlers cooked their pies in long narrow pans. As in the Roman times, the early American pie crusts were often not eaten, but simply used to hold the filling during baking(烘焙).
Over the years, pie has become what it is today --- "the most traditional American dessert". Pie has become so much a part of American culture that we now often use the phrase "as American as apple pie".
51. Which people might probably first grasp the skill to make pies?
A. The Romans.     B. The Greeks.    C. The Englishmen.    D. The Americans.
52. Which of the following is NOT true about pies?
A. English settlers brought pies to America.
B. Early Romans ate not only pies but also the crusts.
C. The Romans first published pie recipe.
D. The word “pie ” became popular because of the Romans` efforts.
53. What can best show pies have become part of American culture?
A. Americans use long narrow pans to cook pies.
B. People use "as American as apple pie" to show something about American characteristics.
C. Americans don't eat crusts but use them to hold the filling during baking.
D. Pies are the most traditional American dessert.
54. The best title of this passage is "______________".
A . The History of Pies                        B. Pies, the Delicious Food
C. Pies, American Dessert                D. How to Make Pies

No one really knows how and why people change as they get older. Also, no theory sufficiently explains all the changes of the aging process. Aging is a complex and varied process that varies in how it affects different people and organs. In fact, even in one person , different organ systems “age “ at a different rate.
At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.
Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.
There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.
What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!
小题1:The underlined phrase “bounce back ”means “__________.”

A．jump backward

B．run fast

C．prevent

D．recover

小题2:In order to make people live longer, scientists _______according to the text.

A．teach people how to eat properly

B．discover how important the exercise is to one’s health

C．study the ways to slow or stop the process of aging

小题3: Many consider the later part of life to be the time of living because they__________.

A．consider their lives have been very successful

B．have come through the battle of life safely

C．know more about themselves and the outside world

D．can have a good rest and enjoy themselves

小题4:How many factors which decide our health are mentioned in the text?

A．Two

B．Four

C．Five

D．Six

Koalas are pictured everywhere in Australia-on cleaning products, on “boxes of chocolate, on sports team shirts. Yet the animals live only in pockets along the east coast.
They once inhabited the entire coastline. The koala population dropped after farmers cut down many of the forests where koalas lived, and

hunters killed the animals for their fur.

By the early 1900s, “koalas were basically shot out of south Australia,” says ecologist Bill Ellis, who studies the relationships among living things and their environments.
I recently joined Ellis and his team in a forest on St Bees Is land, 19 miles off the northeastern coast of Australia, with eight other volunteers. The island is a natural laboratory, yielding findings that may help protect koalas elsewhere on the continent.
The volunteers searched the island for koalas in the blue gum trees. When we found a koala, we gathered information about the trees in the area.
Blue gum is a species of the eucalyptus tree in which the funny leaf eaters spend most of their time. Eucalyptus trees are native to Australia, and their leaves are the main food source for koalas. Although koalas can walk on the ground, they are better suited for life in the canopy, the high cover of branches and leaves in a forest.
What has Ellis’s research told him so far? The population of St Bees seems to be healthy. Yet Ellis wonders whether the koalas might be heading for hard times. The island is overrun with wild goats, and Ellis thinks the goats are eating the small blue gum trees.
Without those trees, the koalas will run out of food in the future. Ellis hopes more research will help him understand how to protect the blue gum trees-and the koalas that depend on them. “I think that’s what everyone is trying to do-to make a difference.” Ellis says.
59. It can be inferred from the first paragraph that     .
A. koalas’ pictures can be found everywhere in the world
B. koalas in Australia like to eat chocolate
C. only in the east coast of Australia can you find koalas
D. you can buy the pictures of koalas only in the east coast of Australia
60. Which of the following is TRUE about koalas?
A. They usually hide in a cave.     B. They feed on the leaves of blue gum trees.
C. They prefer to walk on the ground. D. They don’t adapt to the high cover of branches.
61. What will Ellis most probably start to do next?
A. To keep the population of St Bees healthy.
B. To kill all the goats on the island.
C. To find some new foods for goats.
D. To protect blue gum trees for koalas.
62. The purpose of writing this passage is to      .
A. expect people to concern about the life of koalas
B. record trip to Australia for watching koalas
C. present some basic knowledge of koalas’ life
D. introduce the ecosystem of wildlife in Australia

It looks a bit like the coolers used to keep drinks fresh on asunny day but the cool box being tested in hot Mozambique serves a higher purpose –saving lives from malaria(疟疾).
The new cool box is intended to keep malaria medicines at 25 degrees Celsius(77 degrees Fahrenheir) or below in poor rural areas without electricity where the temperature can reach 45 degrees Celsius.
“At the beginning, the cool boxes will be used to store malarial drugs,” said Parfair Komlan Edah, advisor to John Snow Incorporated, a US company developing the coolers.
“We will change the treatment pattern and procedure because the drugs are expensive and they have to be well stored to be effective,” he said.
The projuct, funded by the US Agency for International Development , started in 2006 and is still at an expermental stage. The coolers are currently being tested in three regions of Mozambique –Maputo, Tete and Zambezia.
The tests will determine whether the coolers are adopted for use nationwide.
In Mozambique , malaria is the leading cause of death among children admitted to pediatric(儿科的) services and there has been an increase in cases of malaira in recent years.
Faced with the sudden increase in malaira, Mozambique’s health ministry last year decided to expand the use fo rapid diagnostic tests for the disease that can give a result within minutes.
The only trouble was that diagnostic tests have to be stored at the temperature of 25 degrees Celsius or below and are currently only available in provincial hospitals that have refrigeration facilities.
“The project was faced with the dilemma(进退两难的处境) of how to ensure quality products despite the hot, humid weather and lack of electricity common in remote health facilities,” Edah said.
The solution was to design”evaporative(蒸发的) coolers”—similar in size to a small refrigerator. The coolers have a water tank at the top that is regularly refilled. When water evaporates from the tank it passes aong wicks that stick out of the cooler, keeping the content s of the box cool/
In a message on World Malaria Day, the World Health Organization(WHO) stresed the importance of national malaira programmes.
Nelson Nkini, head of Proserv, a Mozambican non-governmental group supplying mosquito nets treated with anti-malarial substances, said preventing the disease was cheaper than curing it because of the cost of medicines.
60. If the cool boxes are used,_________.
A. medicines can be stored at any degree Celsius
B. malaria will disapear in Mozambique
C. malaria medicines will be used more effectively
D. the temperature will become lower in Mozambique
61. The situation in Mozambique is that__________.
A. the official department doesn’t know what mianly causes children’s death
B. the project funded by the US Agency for International Development is fighting against malaria.
C. the use of rapid diagnostic tests for malaria is being expanded inth whold country
D. diagnostic tests can be currently available in most rural hospitals.
62. Which can be the best title for the passage?
A. A project in Mozambique
B. Fighting against malaria
C. Preventing the spread of malaria
D. Super cooler gives hope for malaria victims

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they
discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

As A/H1N1 continues to spread, experts from the Centers for Disease Control to the World Health Organization to neighborhood doctors are calling on the people to practice smart flu prevention techniques. Here are some tips to keep body improved and immune（免疫）system ready to fight infection.
Wash Your Hands
And wash them often, in hot soapy water, and for the amount of time it takes you to sing “Happy Birthday” twice.
Get Enough Sleep
This means slightly different things to different people, but try to get 8 hours of good rest each night to keep your immune system in top flu-fighting shape.
Keep Hydrated
Drink enough water each day to clear poisonous matter from your system and keep up good moisture（湿度）production in your body.
Eat Immune-Improving Foods
Keeping you body strong and ready to fight infection is important in flu prevention. Fatty foods can slow your metabolism（新陈代谢）, make you feel inactive, and weaken your immune system. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
Alcohol is likely to decrease your resistance to infections and further damages the immune system. So avoid alcoholic drinks to keep your immune system strong.
Proper exercise-for example walking for 30-40 minutes 3-4 times a week-supports the immune system by increasing circulation, oxygenating the body, removing poisonous material through sweat, and reducing tension and stress. So get moving!
Avoid Contact with Sick People
If you’re coughing or sneezing, cover your mouth(and then wash your hands),and if you have to be around someone who is sick, try to stay a few feet away from them and avoid physical contact.
Know When to Get Help
A/H1N1 can look like regular flu, so don’t feel like you necessarily are infected if you’re exhibiting flu-like symptoms（症状）. But do go to your doctor if you live in an area where there are recorded cases, or if your symptoms are very serious.
44．To fight A/H1N1 infection, it’s helpful for us to_______ .
A．sing “Happy Birthday” while washing hands
B．eat more fatty foods and colorful fruits
C．keep away from alcoholic drinks
D．refuse communication with patients
45．A suitable title for paragraph 7 might be _______.
A．Support the Immune System    B．Keep Physically Active
C．Get Enough Sweat            D．Walk to Reduce Stress
46．The passage seems to suggest that we should_______.
A．get enough sleep after eating fatty foods
B．wash hands with soap after a cough or sneeze
C．drink more water after drinking alcohol
D．see a doctor immediately if you have flu-like symptoms
47．What can help clear poisonous matter from the body?

In recent years advances in medical technology have made it possible for people to live longer than in the past. New medicines and machines are being developed every day to extend life. However, some people, including some doctors, are not in favor of these life extending measures, and they argue that people should have the right to die when they want. They say that the quality of life is as important as life itself and that people should not be forced to go on living when conditions of life have become unbearable. They saw that people should be allowed to die with dignity (尊严) and to decide when they want to die.

The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.
Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.
The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.
Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.
50.We can learn from Paragraph 1 that _______.
A.the first Global Handwashing Day was held in 2005
B.many originations support the idea of Global Handwashing Day
C.Global Handwashing Day was founded by many soap makers
D.the content of Global Handwashing Day is to wash your hand frequently
51.The underlined phrase “critical moments” in Paragraph 2 refers to _______.
A.the turning points
B.schedules
C.the arrangement of a time
D.the necessary parts in health
52.The main purpose of the story is to tell us ________.
A.hand washing is very important
B.to create a culture of hand washing with soap
C.germs can infect ourselves and others
D.soaps play an important role in everyday life
53.The last paragraph implies that ___________.
A.a soap is a kind of medicine to prevent a disease
B.it is important for children to wash hands in a correct way
C.Pneumonia kills about two million children each year
D.Diarrhea is the second leading cause of child deaths.
