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 aren’t resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports, called smart buildings, the structures respond like living organisms to an earthquake’s vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes. The function of the computer mentioned in the passage is to______.
A. counterbalance an earthquake’s action on the building
B. predict the coming of an earthquake with accuracy
C. help strengthen the foundation of the building
D. measure the impact of an earthquake’s vibrations

但是,对于所有的正在进行的激动人心的工作而言,科学远没有达到一个能塑造完美的人的美好新世界的景象——或者甚至于说是塑造一个美好的番茄。在基因治疗普及之前,仍然需要做大量研究。如果许多疾病真的可以治疗的话,那将花上数十年的时间。 就短期而言,遗传筛选将是运用新技术的最可行的办法。在治疗各种DNA缺陷之前,医生能够检测到它们。在某些情况下,这些信息可以延缓疾病的发作或是减轻它的作用效果。例如,一个有着遗传性易患心脏病体质的人可以进行低脂肪的饮食。如果科学家测出由于制造一种重要蛋白质的基因存在缺陷,从而导致这种蛋白质丢失的话,也许科学家就可以给这位病人提供人工蛋白质。然而,在其他的情况下,对于阻止由于基因突变而导致的不幸几乎无能为力。
