[单项选择]Even at the Vatican. not all sacred beliefs are absolute: Thou shalt not kill, but war can be just. Now, behind the quiet walls, a clash is shaping up involving two poles of near certainty: the church’s long-held ban on condoms and its advocacy of human life.
The issue is AIDS. Church officials recently confirmed that Pope Benedict XVI had requested a report on whether it might be acceptable for Catholics to use condoms in one narrow circumstance: to protect life inside a marriage when one partner is infected with H.I.V. or is sick with AIDS.
Whatever the pope decides, church officials and other experts broadly agree that it is remarkable that so delicate an issue is being taken up. But they also agree that such an inquiry is logical, and particularly significant from this pope, who was Pope John Paul II’s strict enforcer of church doctrine.
"In some ways, maybe he has got the greatest capacity to do it because there is no doubt about his orthodoxy," said the. Rev. Jon F
A. the war can be supported by the church

[单项选择]Is nothing sacred Even the idle weekend pastime of skimming stones on a lake has been taken apart and reduced to a mathematical formula.
Everyone knows a stone bounces best on water if it’s round and flat, and spun towards the water as fast as possible. Some enthusiasts even travel to international stone-skimming competitions, like world champion Jerdone Coleman-McGhee, who made a stone bounce 38 times on Blanco River, Texas, in 1992.
Intuitively,a flat stone works best because a relatively large part of its surface strikes the water, so there’s more bounce. Inspired by his eight-year-old son, physicist Lyderic Bocquet of Lyon University in France wanted to find out more. So he tinkered with some simple equations describing a stone bouncing on water in terms of its radius(半径) ,speed and spin, and taking account of gravity and the water’s drag.
The equations showed that the faster a spinning stone is travelling, the more times it will bounce. So no surprise there. To boun

[单项选择]Many experts now believe that even if all space littering were to stop completely, the number of stray objects would continue to increase for centuries. The reason : debris is now so dense that objects will continue to crash into each other, creating even more objects, expanding the rubbish cloud geometrically. "We’ve been saying for years that these things are going to happen," says Nicholas Johnson, head of NASA’s Orbital Debris Program Office. "Until they happen, it’s hard to get people’s interest. "
What seems to best describe Nicholas Johnson’s attitude towards what has happened
A. He is happy that people are starting to pay attention to the problem.
B. He is critical that people have not paid enough attention to the problem.
C. He is objective when commenting on the problem of cosmic junk.
D. He is supportive to what people have done to deal with the problem.
