6 D Providing small classes for at least several grades starting in early primary school gives students the best chance to succeed in late grades, according to groundbreaking new research from a Michigan State University scholar. The research by Spyros Konstantopoulos, a professor of education, is the first to examine the effects of class size over a period and for all levels of students. The study appears in the American Journal of Education. He is also a member of a group for the Department of Education’s Instiute of Education Sciences that will give official advice on class size to the states. He said the advice will mirror his research: the best plan is to provide continuous small classes(13 to 17 students) for at least several years starting in kindergarten or first grade. “For a logn time states thought they could just do it in kindergarten or first grade for one year and get the benefits,” He said. “I don’t believe that. I think you need at least a few years in a row where all students, and especially low-achievers, receive the treatment, and then you see the benefits later.” His research used data from the Project Star study in Tennessee that analyzed the effects of class size on more than 11,000 students in primary and middle school. He found that students who had been in small classes from kindergarten through third grade had actually higher test scores in grades four through eight than students who been in larger classes early on. Students from all achievement levels benefited from small classes, the research found. “But low-achievers benefited the most, which narrowed the achievement gap with high –achievers in science, reading and math, ” he said. Although the study didn’t consider classroom practices, he said the reason for the narrowing gap is likely due to low-achieving students receiving more attention from teachers. “This is especially important in poorer schools because teacher effectiveness matters more in schools with more disadvantaged and low-performing students, ” he said. 48．The professor argues about ________ . A．the size of the class B．the period of the class C．the attention from teachers D．the achievements of students 49．The result of the research shows that _________. A．small classes for one year in early grade are enough B．continuous small classes help students achieve more C．it’s best to attend small classes in kindergarten D．small classes do equal good to students of all levels 50．What can we infer from the passage? A．High achievers will not benefit from small classes. B．Continuous small classes have not been widely accepted. C．Low-achievers should be separated from high-achievers. D．Teachers’ attention matters less than classroom practices. 51．The underlined word “This” in the last paragraph refers to _______. A．the gap between low and high achievers B．continuous small classes C．classroom practices in later grades D．the Project Star Sturdy

9 钓鱼岛是我国固有领土，决不允许别国侵占，近期，为提高警惕保卫祖国，我人民海军为此进行登陆演练，假设一艘战舰因吨位大，吃水太深，只能停锚在离海岸某处．登陆队员需要从较高的军舰甲板上，利用绳索下滑到登陆快艇上再行登陆接近目标，若绳索两端固定好后，与竖直方向的夹角θ=30°，队员甲先匀加速滑到某最大速度，再靠摩擦匀减速滑至快艇，速度刚好为零，在队员甲开始下滑时，队员乙在甲板上同时从同一地点开始向快艇以速度v 0= 3 3 m/s平抛救生圈，第一个刚落到快艇，接着抛第二个，结果第二个救生圈刚好与甲队员同时抵达快艇的同一位置，重力加速度g=10m/s 2，问：（1）军舰甲板到快艇的竖直高度H=？队员甲在绳索上运动的时间t 0=？（2）若加速过程与减速过程中的加速度大小相等，则队员甲在何处速度最大？最大速度多大？（3）若登陆快艇一开始停在离海岸S=1km处（如图），登陆快艇额定功率5KW，载人后连同装备总质量10 3Kg，从静止开始以最大功率向登陆点加速靠近，到达岸边时刚好能达到最大速度10m/s，则登陆艇运动的时间t"=？
