The Good News
Here’s the good news: our air is cleaner, our lakes are purer, our forests are healthier, endangered species are recovering, toxic emissions are down, and acid rain has diminished dramatically.

Media coverage of the environment is heavy on doomsday, but the truth is not at all break: nearly all environmental trends in the United States are positive and have been for years--if net decades.
Eco-legislation, green organizations, corporate cooperation and new inventions have all quietly steered our environment in a positive direction. We can’t afford to be complacent(自满的), though--especially when it comes to greenhouse gases, since global warming is the one huge problem we haven’t really tackled.

[单项选择]Here’s some good news for parents of tweens and teens: You rule.
That may be hard to believe sometimes. And it’s true kids won’t always follow your health and safety rules. But studies show parents who keep setting boundaries make a huge difference.
The latest example is a survey on media use by the Kaiser Family Foundation.

When the Earth shook here on March 26th, 2000, it helped geologists to figure out how the Earth around Seattle would shake during the real thing less than a year later.
When Seattle’s Kingdome was demolished with explosives, more than 200 seismic recorders caught every rattle and roll. Tom Brocher of the U.S. Geological Survey says, "You can see the red waves traveling away from the Kingdome. "
① The areas that shook the worst then also shook the worst when the six point eight (on the Richter scale) Nisqually earthquake hit.
② "We shouldn’t be surprised to see damage at Boeing field and at the port of Seattle where we did see damage, because in both of those areas the ground shook longer and harder than other parts of Seattle."
It’s what’s known as a slab quake (located) 36 miles below the surface where the Juan de Fuca plate slab is diving underneath the North American plate. Geologists believe the plate bent, causing it
A. The plate slab bent, and then cracked, sending shock waves to the surface.
B. The plate was demolished, sending shock waves to the surface.
C. The shock waves traveled to the surface themselves.
D. The shock waves originated from the surfac
