Consider medicine, for instance. No one can deny that medical progress has enriched our lives tremendously. Because of medical advances, we eat better, live easier and are able to take care of ourselves more efficiently. We can cure disease with no more than one injection or a pill. If we have a serious accident, surgeons can put us back together again. If we are born with something defective, they can repair it. They can make us happy, restore our normality, ease our pain, replace worn parts and give us children. They can even bring us back from the dead. These are wonderful achievements, but there is a price we have to pay.
Because medicine has reduced infant mortality and natural death so significantly, the population has been rising steadily, in spite of serious efforts to reduce the rate of population growth. Less than a century ago in the United Stales, infant mortality claimed more than half of the newborn within the first year of life. Medical advances, however, have now reduced that rate to nearly zero. A child born in the United States today has better than a 90% chance of survival. Furthermore, medical advances have ensured that most of these infants will live to be seventy years of age or more, and even that life expectancy increases every year. The result of this progress is an enormous population increase that threatens the quality of life, brought about by progress in the medical profession.
According to this passage, " progress" doesn't always mean that______.
A.something has become stronger and better
B.something has been changed from being one thing to another
C.something has become funny
D.something turns out to be worse than before
(78)Obviously, there would be no point in investing(投入) in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer should come with the following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.
What is the main purpose of this passage?
A.To look back to the early days of computers.
B.To explain what technical problems may occur with computers.
C.To discourage unnecessary investment in computers.
D.To warn against the blindness to the probable shortcomings of computers.
Perhaps the most startling theory to come out of kinesics, the study of body movement, was suggested by Professor Birdwhistell.He believes that physical appearance is often culturally programmed.In other words, we learn our books, but we are not born with them.A baby has generally unformed facial features.A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around family and friends.This helps explain why the people of some regions of the United States look so much alike.New Englanders or Southerners have certain common facial characteristics that cannot be explained by genetics.The exact shape of the mouth is not set at birth;it is learned after.In fact, the final mouth shape is not formed until well after permanent teeth are set.For many, this can be well in adolescence.A husband and wife together for a long time often come to look somewhat alike.We learn our looks from those around us.This is perhaps why in a single country there are areas where people smile more than those in other areas.In the United States, for example, the South is the part of the country where the people smile more frequently.In New England they smile less, and in the western part of New York state still less.Many Southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta, Georgia.People in densely populated urban areas also tend to smile and greet each other in public less than do people in rural areas and small towns.()

However there is another important part of the jobs picture that was targely ovedookcd. There was a big jump in the number of people who report voluntarily working part-time. This figure is now 830,000(4,4 percent)above its year ago level.
Before explaining the connection to the Obamacare, it is worth making an important distinction. Many people who work part-time jobs actually want full-time jobs. They take part-time work because this is all they can get. An increase in involuntary part-time work is evidence of weakness in the labor market and it means that many people will be having a very hard time making ends meet. There was an increase in involuntary part-time in June, but the general direction has been down. Involuntary part-time employment is still far higher than before the recession, but it is down by 640,000(9 percent)from its year ago level.
We know the difference between voluntary and involuntary part-time employment because people tell us. The survey used by the Labor Department asks people if they worked less than 35 hours in the reference week. If the answer is "yes."they are classified as working part-time. The survey then asks whether they worked less than 35 hours in that week because they wanted to work less than full time or because they had no choice. They are only elassified as voluntary part-time workers if they tell the survey taker they chose to work less than 35 hours a week.
The issue of voluntary part-time relates to Obamacare becanse one of the main purposes was to allow people to get insurance outside of employment. For many people, especially those with serious health conditions or family members with serious health conditions, before Obamacare the only way to get insurance was through a job that provided health insurance.
However, Obamacare has allowed more than 12 million people to either get insurance through Medicaid or the exchanges. These are people who may previously have felt the need to get a full-time job that provided insurance in order to cover themselves and their families. With Obamacare there is no longer a link between employment and insurance.
