scientists had good news to report: The damage and death toll(死亡人数) could have been much worse. More than 60 people died in this earthquake. By comparison, and earthquake of similar __1__ that shook America in 1998 claimed 25,000 victims.

Injuries and deaths were __2__ less in Los Angeles because the quake occurred at 4:31 a.m. On a holiday, when traffic was light on the city's highway. In addition, __3__ made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more __4__ to quakes.

In the past, making structures quake-resist-ant meant firm yet __5__ 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 __6__ the impact of ground vibrations. The most __7__ 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 ground shakes and the building tips forward, the computer would __8__ the building to shift in the opposite direction. The new designs should offer even greater __9__ to cities where earthquakes ofen take place.

The new smart structures could be very __10__ to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

In looking at the class structure of an entire system, we may find that its inheritance (1) is either wide and shallow, narrow and deep, or balanced. Class structures that are wide and shallow usually represent forests of (2) classes that can be mixed and matched. Class structures that are narrow and deep represent trees of classes that are related by a common ancestor. There are advantages and disadvantages to each approach. Forests of classes are more loosely (3) , but they may not exploit all the commonality that exists. Trees of classes exploit this commonality, so that individual classes are smaller than in forests. However, to understand a particular class, it is usually necessary to understand the meaning of all the classes it inherits from or uses. The proper shape of a class structure is highly problem-dependent. We must make similar trade-offs among inheritance, aggregation, and using relation- ships. For example, should the class Car inherit, contain, or use the classes named Engine and Wheel？ In this case, we suggest that an (4) relationship is more appropriate than inheritance relationship. Meyer states that between the class A and B," (5) is appropriate if every instance of B may also be viewed as an instance of A. The client relationship is appropriate when every instance of B simply possesses one or more attributes of A". From another perspective, if the behavior. of an object is more than the sum of its individual parts, then creating an aggregation relationship rather than an inheritance relationship between the appropriate classes is probably superior.
