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
In 274 pages Sagan deals with everything from the formation of the Earth to the puzzling possibilities of contact with extra-terrestrial life. This is the moment in history when man's stepping into the universe has suddenly become conceivable. To Sagan this is more exciting and important than was the exploration of the New World in the sixteenth century. So expenditure on the space programme, pruned of recent excesses, ought to continue--it is, according to Sagan, no larger a part of America's gross national income than was the relative cost to England in the sixteenth century of exploration in sailing ships.
The book is not for scientific illiterates, nor is Sagan a pedestrian scientist. Although he makes short work of the unidentified foreign objects (UFO) spotters, he is unafraid to take us on a speculative journey to a black hole which, for all he knows, might be the quick route to somewhere else, not necessarily our universe.
Sagan exhibits a passionate interest in life in the cosmos in which there are .almost certainly civilizations much more advanced than our own. We are the result of a number of relatively recent cosmic accidents, but for all that, Sagan is no less excited about our future,
From the passage we understand that Carl Sagan writes ______.
A．forcefully and complexly
B．elaborately and literally
C．simply and humorously
D．snobbishly and cleverly

The dollar also dipped to a nearly five-year low against the yen, but later regained ground.
Yesterday, the euro rose to $1.3329 in early trading before dipping back to $1.3290 later in New York. The euro topped $1.32 for the first time the day before in European trading. US markets were closed Thursday for the Thanksgiving holiday.
The dollar also traded near its lowest levels since December 1999 against the Japanese yen yesterday, slipping to 102.56 yen, down from 102.81 late Wednesday in New York.
One reason the euro has kept rising is a lack of concerted action by central banks to support the dollar by selling holdings of the other major currencies.
"$1.35 is definitely on the cards now, as for how soon we'll get there, I'm not sure," said Riz Din, a currency analyst with Barclay's Capital in London.
"It increasingly looks as if, despite weaker data in the euro area, the prospects for intervention, are very, very low at current rates."
The latest dollar collapse, fueled by concerns over the US trade and budget deficits, has taken the euro from around $1.20 about two months ago.
Because the euro's rise tends to make European products more expensive, European leaders have voiced fears that it might hurt the continent's export-driven economic recovery. The European Central Bank's president has called the rapid increase "brutal".
But the dollar's weakness is good news for US exporters, helping make American products less expensive overseas.
Commerzbank economist Michael Schubert said speculation against the dollar was making its slide "a bit faster than I had expected".
"Obviously, it's difficult to stop the train," Mr. Schubert said in Frankfurt. A combination of intervention by central banks and positive US economic data could apply the brakes, he added.
Economists say the European Central Bank (ECB) is wary of intervening in the currency markets on its own and the United States Would be unlikely to join in such a move.
According to the text, the dollar
A．has reached its lowest level against euro yesterday.
B．was lower than euro in the past four continuous days.

Propositional meaningis also referred to assentence meaning. To know the meaning of a sentence is to know what the sentence is all about, and what, who, where, when and how are involved. The following sentences differ in their structure, but they share the same propositional content:
Her colleague regard her as being less than bright.
She is regarded as being less than bright by her colleague.
She strikes her colleague as being less than bright.
In other words, the above three sentences can be used to paraphrase each other's propositional meaning, and therefore paraphrasing becomes a very useful device to help us to check our understanding of the propositional content of a sentence.
