The food we eat seems to have great effects on our health. Although science has made great 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 illnesses are related to diet and forty percent of cancer is related to diet as well. Different cultures are subject to certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery.
In 1945, government researchers realized that nitrates(硝酸盐) and nitrites(亚硝酸盐), commonly used to keep color in meats, and other food additives, caused cancer. Yet, these additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels(标签) of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to cows and chick and because of this, penicillin has been found in the milk of treated cows.
Sometimes similar drugs are given to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although the FDA has tried repeatedly to control these, the practices continue.
How has science done a bad service to mankind?

A．Diseases caused by food have been done away with.

B．It has caused a lack of information about the value of food.

C．Some harmful materials have been added to our food.

D．Scientists have made food more expensive to eat.

What are nitrates used for?

A．They help process packaged food.

B．They keep the color in meats.

C．They cure diseases of cows and chickens.

D．They cause the animals to become fatter.

Which of the following statements is NOT true?

A．You can find out harmful additives on the packaging labels of food.

B．Drugs given to animals are not all for medical reasons.

C．Researchers knew about the harm of food additives about 60 years ago.

D．Food may cause forty percent of cancer in the world.

According to the passage, the FDA might be _________.

A．an organization which controls the safety of food

B．a producer which makes additives

C．a factory which processes food

D．a hospital which cures cancer

The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you．Air pressure is a wonderful force．When you swim underwater, you can feel water push down your body．The air all around you does the same．However, your body is so used to it that you do not notice this．The pressure is caused by a layer of air called the atmosphere．This layer surrounds the Earth, extending to about five kilometers above the Earth's surface．
The following experiment is an easy one that you can do at home．But make sure that you are supervised, because you will need to use matches．
What you need
·A hard-boiled egg without the shell
·A bottle with a neck slightly smaller than the egg
·A piece of paper
·A match
Method
1）Check that the paper will sit firmly on the neck of the bottle．
2）Tear the paper into strips and put the strips into the bottle．
3）Light the paper by dropping a burning match into the bottle．
4）Quickly sit the egg on the neck of the bottle．
Result
Astonishingly, the egg will be sucked into the bottle．Your friends will be amazed when you show them the experiment．But be careful when you handle matches．
Why it happened
As the paper burns, it needs oxygen and uses up the oxygen （air）in the bottle．The egg acts as a seal in the neck of the bottle, so no more air can get inside．This reduces the air pressure inside the bottle．The air pressure must equalize, so more air from outside must enter the bottle．The outside air presses against the egg and then the egg is pushed into the bottle! That proves that air is all around and that it is pressing down on it．
Why is there the need to take care when you are doing the experiment?

A．The bottle could break．

B．You need to light the paper with a match．

C．The egg needs to be shelled．

D．The egg has to be perfectly placed on the neck of the bottle．

In the experiment, the burning inside the bottle can__．

A．equalize the air pressure inside and outside

B．make a seal in the neck of the bottle

C．finish up the oxygen inside the bottle

D．produce more oxygen inside th

e bottle

How did the egg put into the bottle?

A．The oxygen inside the bottle sucked the egg in．

B．It became salt without the shell．

C．The neck of the bottle was wide enough．

D．The outside air pressure forced it into the bottle．

The experiment is carried out to prove ____．

A．water pushes on your body when you swim underwater

B．the earth is surrounded by a layer of air called the atmosphere

C．the pressure of air around us has a powerful force

D．the air pressure is not equalized around us

Preparing for the Next Job Market
The latest spike in the unemployment rate is being felt across the board ?in 98 percent of metropolitan areas, in high-wage and low-wage jobs, among young and old, women and men, but especially men．
This landscape means that young Americans who are trying to plan their futures right now have some hard choices．Do they go to college and take on debt without hope of getting a job? And what about high school students? Do they have any chance of securing a job without a college degree? Perhaps the education system needs to react to this rapidly moving economic crisis．
In our current economic collapse, the connection between education and employment could not be more different than it was during the Depression．Education must now hold center stage, not because of an enemy abroad but because of the global economy．The jobs of the future will demand levels of education, particularly skills in mathematics, technology and science, which exceed those now taught in high school．
A healthy society should strive for full employment．In our times, that goal cannot be realized, or even approximated by creating jobs for the unskilled．The long-term prospect for economic recovery depends on the extent to which we improve our educational system．And this is where America is now at its weakest．
Our high schools produce graduates who do not write well enough, have limited reasoning skills and are unable to use the tools of mathematics．Their command of science is far inferior to that of their counterparts in other nations．And all too many young people drop out．We may still have the best university system, but it benefits only a minority．
We will need more engineers, scientists and service providers, particularly in the health professions, with a quality of education that cannot be obtained in the current system．Radical change, not reform, is called for．
What should be done? First, high school should be cut short and end when students are 16．Second, a new generation of two-year college programs tied to a wide range of specific skills that the economy needs should be created．Third, access to four-year colleges should be expanded, giving more Americans the chance to acquire the deep learning that makes breakthroughs in technology possible．Fourth, we need to recruit more public school teachers and train them better, particularly in physics, chemistry, biology and mathematics, so that our children can be prepared to compete．
Nowadays, students graduating from high school____．

A．write well enough

B．have limitless reasoning skills

C．can't use the tools of mathematics

D．command science as much as their counterparts in other nations

What should we do to improve the quality of education?

A．Students shouldn't study in high school until 16．

B．We should create a new generation of two-year college programs tied to a wide range of specific skills the economy needs．

C．We should limit access to four-year colleges．

D．We ought to recruit more private school teachers and train them better．

What does the word "collapse" in the third paragraph mean?

A．success

B．failure

C．

development

D．booming

Which of the following is NOT true according to the passage?

A．Young Americans planning their futures have difficult choices．

B．Education must hold center stage due to the global economy．

C．The best university system benefits a majority．

D．A health society should struggle for full employment．

Most people feel lonely sometimes, but it usually lasts only a few minutes or a few hours．This kind of loneliness is not serious．In fact, it is quite normal．For some people, though, loneliness can last for years．Now researchers say there are three different kinds of loneliness．
The first kind of loneliness is temporary．This is the most common type．It usually disappears quickly and does not need any special attention．
The second kind, situational loneliness, is a natural result of a certain situation, for example, a family problem, the death of a loved one, or moving to a new place．Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year．
The third kind of loneliness is the most severe．Unlike the second type, chronic （长期的） loneliness usually lasts more than two years and has no specific cause．People who experience habitual loneliness have problems socializing and being close to others．Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition．
Psychologists agree that one important factor in loneliness is a person's social contacts, such as friends, family members, co-workers, etc．We depend on various people for different reasons．For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share interests and activities．However, psychologists have found that, though lonely people have many social contacts, they sometimes feel they should have more．They question then" own popularity．
Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease．While temporary and situational loneliness can be a normal and healthy part of life, chronic loneliness can be a very sad and sometimes dangerous condition．
Which of the following can be the cause of situational loneliness?

A．Sleeplessness．	B．Changing work．
C．Heart disease．	D．Social contacts．

The underlined word "it" in the last sentence of the third paragraph refers to _____ ．

A．headaches	B．situational loneliness

C．Loneliness doesn't affect people much．

D．Scientists have found ways to help habitually lonely people．

I was born and raised in Hong Kong．For the past six years, I've been living in the United States．I work as a salesgirl in a large department store．Right now I'm going through a difficult period of my life which is hard for me to talk about．
