一、根据以下资料，回答101-105题。

根据全国第二次农业普查资料，2006年末，浙江实有耕地面积为1594.43千公顷，分别比 1980年、1985年、1990年、1996年、2000年减少12.5%、10.3%、7.5%、1.2%和0.8%，其中水田面积为1291.08干公顷，分别比1980年、1985年、1990年、1996年、2000年减少12.0%、10.5%、 9.7%、4.0%、2.8%。
随着第二、三产业发展，农民剩余劳动力转移，收入途径拓宽。与此同时，浙江农民人均土地逐年减少，农民经营农业规模不断缩小，收益相对下降，农民对农业经营投入下降。但多数农民身份没变，不敢完全放弃对承包到户土地的控制权，仍将土地看作家庭生存的保障之一，使浙江农业成为多数农户的副业，导致经营农业规模不断缩小、效益下降。2006年，浙江农村居民人均纯收人为7335元，从1996-2006年，各年份保持不同程度的增长，年平均实际增长6.8%； 2006年，浙江人均耕地面积为0.034公顷，比1980年下降28.2%；农民经营农业收入占人均纯收入的比重从1985年的37.3%下降到2006年的12.0%；农业生产户数为808.26万户，占农村住户数的66.2%，比2003年下降14.5个百分点；其中纯农户所占比重为19.5%，非农业兼业户达60.1%。
2006年，浙江牧业总产值为287.34亿元，占全省农、林、牧、渔业总产值的19.0%；1996-2006年年均增长为4.4%，比全省农、林、牧、渔业总产值年均增长高1.1个百分点；农民纯收人中，牧业的农民家庭经营收入为281元，占家庭经营收入的9.3%，1996-2006年的年均增长为 2.0%，分别比第二、三产业的经营收入的年增长率低8.8和8.0个百分点。
在先发优势不断减弱的情况下，农村的第二、三产业发展难度加大，农民经营非农产业的收入增长趋缓。浙江农民工资性收入与家庭经营非农产业收入在农民纯收人中占有较高比重。农村的第二、三产业发展是构成浙江农民上资性收入和家庭经营非农产业收入的主要来源。随着市场经济发展，要素资源不断匮乏，并向大企业倾斜，非农产业的创业成本不断提高，与农民收入关系紧密的农村第二、三产业发展趋缓，导致农民工资性收入和家庭经营非农产业收入增长趋缓。从浙江个体工业单位发展情况看，2007年单位数为67.5万户，2001-2007年年均增长 2.8%。

下列各项，数值最小的是( )。

A．1985年比2006年的实有耕地面积多的百分比

B．2003年农业生产户数占农村住户数的比重

C．第二产业经营收入的年增长率

D．2001-2007年个体工业单位年均增长率

答案

参考答案：D

解析： A项，2006午末，浙江实有耕地面积为1594.43千公顷，比1985年减少10.3%，则1985年实有耕地面积为1594.43÷(1-10.3%)，那么1985年比2006年实有耕地面积多了1594.43÷(1-10.3%)÷1594.43-1=≈11.5%；B项，2006年农业生产户数占农村住户数的66.2%，比2003年下降14.5个百分点，所以2003年比重为66.2%+14.5%=80.7%；C项，牧业的农民家庭经营收入1996-2006年的年均增长为2.0%，比第二产业经营收入的年增长率低8.80个百分点，所以第二产业经营收入的年增长率为2.0%+8.80%=10.8%；D项，个体工业单位2007年单位数为67.5万户，2001-2007年年均增长2.8%。所以选择D。

问答题

There is an ever-widening gap between black male college enrollees and their female and white counterparts, says the American Council on Education (ACE).
Twenty years ago, according to ACE’s "Annual Status Report on Minorities in Higher Education," 30 percent of African American male high school graduates (ages 18 to 24) were enrolled in college, compared with 28 percent of same-age black females and 41 percent of white males.
Now, some 37 percent of black men are enrolled, compared with 42 percent of African American women and 44.5 percent of white males. So while there are more black males enrolling in college today than 20 years ago, other groups have outstripped them in enrolling and, even more importantly, in retention rates.
The graduation rate of black men is lower than that of any group. Only 35 percent of black males enrollees graduated within six years from colleges in 1996, compared with 59 percent of white males, 46 percent of Hispanic men, 41 percent of American Indian males and 45 percent of the black women who entered the same year.
Surveys and reports are hinting that the country’s educational apparatus is stacked against the black male. Fewer than one in five students of color have graduated from high school, have a set of college-prep courses on their high school transcripts and "demonstrate basic literacy" -- the necessities for being "college ready."
Another glaring problem is that black males are disproportionately labeled as discipline and behavioral problems and fast tracked out of high schools through expulsions and suspensions.
As if that’s not enough, says ACE’s William Harvey, there’s a virtual drying up of federal aid-to-education grant money coupled with jacked-up tuitions, which make it necessary for low-income students to assume an average ＄ 20,000 debt to finish a four-year curriculum.
"For those in the lower economic category, the availability of financial aid determines who gets to go to college and who doesn’t," observes Harvey.
Harvey points out that, over the years, federal funding has undergone a "complete reversal," from "a 70 percent to 30 percent grant-to-loan ratio 20 years ago" to the exact opposite today.
"An 18-year-old male will be more inclined to say, ’I want money in my pocket now’ and attempt to get a job," adds Harvey. "But many take on the debt, become part-time students, work 20-plus hours a week and become five-year students at a four-year college."
The inequity of that educational apparatus is especially clear when you look at the black males who persevere -- those who go on to finish high school, earn a bachelor’s degree and even finish grad school.
A recently released Census report shows that, whether they have a high school diploma or a master’s degree, black men will earn roughly 25 percent less than Whites.
