Passage FourMore than 6,000 children were expelled (开除) from US school last year for bringing guns and bombs to school, the US Department of Education said on May 8.The department gave a report to the expulsions (开除) as saying handguns accounted for 58 percent of the 6,093 expulsions in 1996 and 1997, against 7 percent for rifles (步枪) or shotguns and 35 percent for other types of firearms."The report is a clear sign that out nation's public schools are cracking down (严惩) on students who bring guns to school," Education Secretary Richard Riley said in a statement. "We need to be tough-minded about keeping guns out of our schools and do everything to keep our children safe."In March 1997, an 11 years old boy and 13 years old boy using handguns and rifles shot dead four children and a teacher at a school in Jonesboro, Arkansas. In October, two were killed and seven wounded in a shooting at a Mississippi school. Two months later, a 14 years old boy killed three high school students and wounded five in Dasucah, Kentucky.Most of the expulsions, 56 percent, were from high school, which have students from about age 13.34 percent were from junior high schools and 9 percent were from elementary schools, the report said.46. From the first paragraph we can infer that in the US schools ______.A. students enjoy shootingB. students are eager to be soliderC. safety is a problemD. students can make guns
共用题干第二篇Sino-Japan Animosity（敌意）LessensChinese and Japanese people view each other slightly more positively than last year,according to a survey released on Wednesday at a press conference in Beijing.The survey is jointly sponsored by China Daily and Genron NPO（非营利性的组织）,a Japanese think tank similar to the American Council on Foreign Relations.It also found an overwhelming agreement in both countries that Sino-Japanese relations were important.The survey is a part of the Beijing-Tokyo Forum,an annual gathering of senior government officials and representatives from Chinese and Japanese NGOs（非政府组织）designed to improve communication and understanding between the Iwo countries.Conducted every year for five years now,the survey focused on two different groups of people:ordinary citizens,and intellectuals.In China,the intellectual group was comprised mainly of university students from well-known schools like Peking University.In Japan,the intellectual group was mainly made up of previous members of Genron NPO.Among ordinary Chinese polled,35.7 percent said they have"very good"or"relatively good" impressions of Japan,a 5.5-percentage-point increase compared with last year. 45.2 percent of Chinese students had a positive impression of Japan,two percentage points more than last year. Only 26.6 percent of Japanese have a positive impression of China,however.Still,an overwhelming majority of the respondents from each country said Sino-Japanese relations were "important"and wanted their leaders to deepen talks and cooperation with each other.But 51.9 percent of ordinary people and 42.4 percent of students in China said they saw no change in relations between the two countries over the last year. In Japan,64.8 percent of those ordinary people and 53.4 percent of intellectuals surveyed shared the view that there was no improvement in bilateral ties thisyear.Historical issues and territorial disputes remain two major obstacles to improving bilateral relations,the survey found.What concerns the Chinese most are historical issues:visits by Japanese officials to YasukuniShrine（靖国神社）,and the Nanjing Massacre（大屠杀）.Perceptions on economic and trade relations have improved,though.About 47 percent of ordinary Japanese said China had been"helpful"this year in fighting the global economic crisis,compared with just 30 percent last year. The percent of Japanese intellectuals who said Chinese economic growth was good for Japan increased from 65.8 percent to 81.4 percent this year.Cooperation in East Asia issues,trade and investment,energy,the environment and climate change top the list of common concerns that people in China and Japan want their leaders to talk about in bilateral meetings,the survey found.Civil exchanges were regarded by most people from both countries as an important way to improve relations.90. 7 percent of the students and 85.7 percent of the ordinary people in China and 95.8% of intellectuals and 74.8% of the ordinary people in Japan viewed civil exchanges as"important"or"relatively important".Chinese and Japanese both learn about each other's country mostly through television news and newspapers,the survey found.Which of the following statements about the survey is true?A:The survey was conducted on Wednesday at a press conference in Beijing.B:The survey is jointly sponsored by China Daily,Genron NPO and the American Council on Foreign Relations.C:The survey found that people in both China and Japan generally agree that the relationship between the two countries is important.D:The survey mainly focused on two different groups of people:ordinary citizens,and the university students.

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.
