41. ______.
Why does the universe exist To put it another way, why is there something instead of nothing Since the 1920s, scientists have known the universe is expanding, which means it must have started at a definite time in the past. They even have developed theories that give a detailed picture of the evolution of the universe from the time it was a fraction of a second old to the present. Over the next couple of decades, these theories will be refined by data from extraordinary powerful new telescope. We will have a better understanding of how matter behaves at the unfa

"We’ll give the dispenser(药剂师) something to do. If we go on prescribing these, he’ll lose his cunning."
The students laughed, and the doctor gave them a circular glance of enjoyment in his joke. Then he touched the bell and, when the porter poked his head in, said: "Old women, please."
He leaned back in his chair, chatting with the house-physician while the porter herded along the old patients. They came in, strings of anemic girls, with large fringes and pallid lips, who could not digest their bad, insufficient food; old ladies, fat and thin, aged prematurely by frequent confinements, with winter coughs; women with this, that, and the other, the matter with them. Dr. Tyrell and his house-physician got through them quickly. Time was getting on, and the air in the small room was growing more sickly.

"Copy the ways of nature," we were told. Yes, copy nature — for everything comes directly or indirectly from natural things. Often we have to put our knowledge to work, "treating" nature’s materials so as to make them serve our purposes better. We could, certainly, take the skin from a dead animal and at once make a pair of shoes with it; but they wouldn’t be very good shoes. For our purpose it is better first to treat the skin with chemicals that turn it into leather.
Until fairly recently our efforts to copy nature’s methods of manufacture were not very successful. Up to about 1950 only animal skins provided material for good shoes. Clothes had to be made of cotton from the cotton plant or of wool from sheep. The only kind of rubber we had came from the rubber tree. Close study of all such useful materials showed that their chemistry was simple in some ways, most complicated in others. Their basic chemicals are plentiful &mdas
A. An animal’s skin can be made into a pair of shoes for us.
B. Our purposes are not necessarily those of Nature.
C. There aren’t enough natural materials for our needs.
D. We try to copy nature — but it is difficult to do that.

"We’re using the wrong word," says Sean Drysdale, a desperate doctor from a rural hospital at Hlabisa in northern KwaZulu-Natal. "This isn’t an epidemic, it’s a disaster. " A recent UNIEF report, which states that almost one-third of Swaziland’s 900,000 people are infected with HIV, the virus that causes AIDS, supports this diagnosis. HIV is spreading faster in southern Africa than anywhere else in the world.
But is anyone paying attention Despite the fact that most of the world’s 33.5 million HIV/AIDS cases are in sub-Saharan Africa—with an additional 4 million infected each year—the priorities at last week’s Organization of African Unity summit were conflict resolution and economies development. Yet the epidemic could have a greater effect on economic development—or, rather, the lack of it—than many politicians suspect.
While business leaders are more concerned about the 2K mi

B. All the countries must fight against AIDS problems to protect their economy
