Each year millions of babies are born too soon and too small. Premature or preterm births are defined as births at less than thirty-seven weeks.
Prematurity is the leading cause of death in newborn babies. More than one-fourth of the four million newborns who die each year around the world were born too early.
Preterm babies that survive can suffer a lifetime of serious health conditions. The examples include cerebral palsy, blindness, hearing problems and learning disabilities. Families and communities face emotional, physical and financial costs.
Christopher Howson is the vice president for global programs at the March of Dimes, a nonprofit group. His group and the World Health Organization recently published a report called “The Global and Regional Toll of Preterm Birth.”
CHRISTOPHER HOWSON: “Frankly the crisis of preterm birth is under-recognized, undercounted, undervalued and underfunded. I mean, this report shows that thirteen million babies are born every year preterm, and that over a million of those babies die as a result of being born too early.”
And these are just estimates; the true numbers could be even higher. More than eighty-five percent of preterm births happen in Africa and Asia. Africa has the highest rate, with about four million cases each year.
Chris Howson says many of the causes of preterm births are related to poverty and weak health-care systems.
CHRISTOPHER HOWSON: “For example, the poor overall health and nutritional status of women. A high burden of infectious diseases. Lack of provision of family planning – allowing a woman to decide when to start and end having children and how to space her children. And also the lack of good prenatal care programs that might identify problems early on in pregnancy.”
Preterm births are a problem not just in the developing world. The combined rate in the United States and Canada is the second highest in the world. Preterm birth rates in the United States have increased thirty-six percent in the last twenty-five years.
This has been largely the result of two reasons. One is an increase in pregnancies among women over age thirty-five. The other is an increase in the use of reproductive therapies.

Attitude isn’t quite everything when it comes to being successful, but attitude plays a part in every stage of your life. A poor attitude gets more people fired than any other single factor, and a good attitude gets people jobs and helps them keep those jobs more than any other factor.
Your attitude affects many people, from your family to the stranger on the street corner. Your attitude is particularly important when you face seemingly hopeless situations. Losing a job or friend because of a poor attitude is unfortunate.
You can find at least two ways to look at everything. A pessimist looks for difficulty in the opportunity, while an optimist looks for opportunity in the difficulty. A poet of long ago put the difference between optimism and pessimism this way: Two men looked out from prison bars – one saw mud; the other saw stars.
Unfortunately, many people look only at the problem and not at the opportunity that lies within the problem. Many employees complain about the difficulty of their jobs, for example, not realizing that if the job were simple, the employer would hire someone with less ability at a lower wage. A small coin can hide even the sun if you hold the coin close enough to your eye. So when you get too close to your problems, to think objectively about them, try to keep in mind how your vision can be obstructed. Take a step back, and look at the situation from a new angle.
You can’t do anything to change the fact that a problem exists, but you can do a great deal to find the opportunity within that problem. You’re guaranteed a better tomorrow by doing your best today and developing a plan of action for the tomorrows that lie ahead. Just remember to maintain a positive mental attitude.

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．
72．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．
73．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 the bottle
74．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．
75．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．
68．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
69．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．
70．What does the word "collapse" in the third paragraph mean?
A．success B．failure C．development D．booming
71．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．
64．Which of the following can be the cause of situational loneliness?
A．Sleeplessness． B．Changing work．
C．Heart disease． D．Social contacts．
