Remember to write the answers on the Answer Sheet.　　High Dropout Rate in US　　Many young people in the United States never finish high school. Exactly how many dropouts is another issue. Recent studies of dropout rates have had conflicting results. For one thing, schools define and measure their dropout rates differently.　　Some researchers say about fifteen to twenty parents of public school students do not complete their education. But many other experts and policymakers believe that for the past twenty years, the dropout rate has been around thirty percent. For Latino and black students, the numbers are even higher. Researchers say almost half of them leave school.　　At the same time, almost half the states let students leave school before the age of eighteen without informing their parents.　　Finding a good job without a high school education is more and more difficult. A Northeastern University study in 2002 found that almost half of all dropouts aged sixteen to twenty-four did not have a job.　　The lack of high school education can also lead to other problems. An estimated two-thirds of prisoners in the United States dropped out of high school.　　Recent studies have shown that the majority of students who drop out do not do it because they are failing. Many are bored with their classes or feel disconnected from their school and teachers. Some students feel that educators place low expectations on them. Teen pregnancies also add to the dropout problem.　　During the past twenty years, there have been efforts to increase graduation rate through education reforms. Some communities are working on dropout prevention programs. These include alternative high schools to meet special needs.　　Some programs, for example, provide free transportation and childcare to help young mothers and fathers finish school. Yet special programs can cost a lot, and many school systems have limited budgets.　　Federal spending on second-chance programs to help students finish school has decreased from the 1970s. This was shown in a report last year from the Educational Testing Service.　　Experts suggest early warning systems to help identify young schoolchildren at risk of dropping out of high school. They say schools also need to get parents more involved, especially if their children are missing school often.　　Questions:　　1．What is the researchers’ estimated percentage of school dropouts among Latino and black students?　　2．What efforts have been made to increase graduation rates?　　3．What has been done to help young parents complete their education?　　4．Who made a report about the decrease，of Federal spending on second-chance programs to help students finish school?　　5．What do experts suggest setting up to help prevent students from dropping out of school?

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.
