After the violent earthquake that shook
Los Angeles in 1994, earthquake scientists had good news to report: the damage
and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25, 000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city’s highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city’s buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers are not resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings.

A. ノ-ト B. エレベ-タ- C. スト-ブ D. フォ-ク [单项选择]Conservationists may be miscalculating the numbers of the threatened animals such as elephants, say African and American researchers. The error occurs because of a flaw in the way they estimate animal numbers from the piles of dung the creatures leave behind.
The mistake could lead researchers to think that there are twice as many elephants as there really are in some regions, according to Andrew Plumptre of the Wildlife conservation Society (WCS) in New York. Biologist Katy Payne of Cornell University in Ithaca, New York, agrees. "We really need to know elephant numbers and the evidence that we have is quite indirect," says Payne, who electronically tracks elephants. Counting elephants from aeroplanes is impossible in the vast, equatorial rainforests of Central Africa. So researchers often estimate elephant numbers by counting dung piles in a given area. They also need to know the rate at which dung decays. Because it’s extremely difficult to determine these rates A. "endangered" B. "frightened" C. "died" D. "angered" [判断题]天麻与全蝎既治小儿急惊,又治脾虚慢惊。( )
