题目内容
【题目】下表显示X、Y两地同年出现地震的有关资料。X地位于美国西部，Y地位于印度中部。读表回答问题。
地点 | 人口密度(人/km2) | 震中距(km) | 地震发生时间(地方时) | 震级(级) | 死亡人数(人) |
X | 200 | 5.8 | 10：25 | 7.4 | 8 |
Y | 500 | 2.5 | 4：00 | 7.1 | 1 820 |
【1】
A. X地的震源深度大于Y地
B. X地地震产生的能量大于Y地
C. X、Y两地都不位于震中
D. X、Y两地的地震均属于破坏性地震
【2】
A. Y地人口密度较大
B. Y地距震中较近
C. Y地的地震发生在夜间
D. Y地位于板块边界地带
【答案】
【1】A
【2】D
【解析】试题分析：
【1】分析上面表格可知，两地地震未明确给出震源深度，所以无法确定X、Y两地震源深度。故A项说法不可靠。X地地震震级7.4，高于Y地的7.1，X地产生的能量大于Y地，B项正确。两地震中距均大于0，表明X、Y两地都不位于震中，C项正确。两地地震震级均大于5级，故X、Y两地的地震均属于破坏性地震。
【2】分析上表可知，Y地（印度中部）人口密度较大、距离震中较近、地震发生在大多数居民尚熟睡的夜间，故死亡人数较多。Y地（印度中部）位于印度洋板块中北部，距板块边界较远，故D项错误。综合以上分析可知，D为符合题意的选项。

Harvard University health policy researcher Ellen Meara says scholars have found some clues as to why some groups of people have more or less disease than others. She says one important factor in people's health is the amount of education they have.
In her most recent paper, Meara looked at data from the United States census(人口普查). These counts of people occur every 10 years. Meara and her colleagues examined data from several decades.
Meara says they found that in 1990, a 25-year-old who only had some secondary school could expect to live for a total of 75 years. In 2000, a 25 year old with some secondary education could also expect to live to the age of 75.
In contrast, for a better educated 25-year-old, they could expect to live to the age of 80 in 1990. Someone with a similar education level in the year 2000 could expect to live to be more than 81 years, 81.6 years to be exact.
Meara says, not only do better-educated people live longer to begin with, but in the past ten years, more educated people have made gains in the length of their lives. Meanwhile, the life expectancy hasn’t changed for less educated people.
Some of these gains can be explained. Meara says researchers know that people who are more educated are more likely to quit smoking cigarettes, or not start at all, compared to people with less education.
“I think it’s a reminder not to be satisfactory,” Meara says. “Just because a population overall appears to be getting healthier, it doesn't always mean that those advantages and successes that many people have enjoyed really extend into all parts of the population. And I think that's something to really pay attention to regardless of whether you live in the US or elsewhere.”
Meara points out that education can often determine income — people with more education frequently make more money. This makes them aware of health care, and purchase other resources and services that can keep them healthier. But the data on income do not show that people who make more money are automatically healthier. Meara says education is key. People need to be educated in order to take advantage of opportunities for better health.
