D.多层住宅的交通组织垂直交通以楼梯间为枢纽,必要时辅助以走廊

答案

参考答案:A

解析: 外廊式住宅,它在联排式低层住宅,多层、高层的板式住宅和“Y”型、工字型的点式住宅中普遍采用。它的交通方式是在房间的一侧设有公共走廊,走廊的一端通向楼梯和电梯。它可以分为:长外廊和短外廊两种,长外廊一梯每层可以服务许多户,短外廊一梯每层可以服务3~5户。外廊也可分为:封闭式和敞开式两种,前者多在多层、高层住宅中使用,采用柱子、栅栏和玻璃等围护。外廊式住宅的特点是:分户明确,每间或每套住房自公共走廊有一个出入口,每户均可获得较好的朝向,采光通风好。它的特点是:外廊作为公共交通走道,所占的面积较大,建筑造价较高;同时,每户的门对着公共走廊,相互干扰较大。

Galloway, a mostly middle-class community northwest of Atlantic City, is part of a wave of districts across the nation trying to remake homework amid concerns that high-stakes testing and competition for college have fueled a nightly grind that is stressing out children and depriving them of play and rest, yet doing little to raise achievement, particularly in elementary grades.

Such efforts have drawn criticism from some teachers and some parents who counter that students must study more, not less, if they are to succeed. Even so, the anti-homework movement has been reignited in recent months by the documentary Race to Nowhere, about burned-out students caught in a pressure-cooker educational system. "There is simply no proof that most homework as we know it improves school performance," said Vicki Abeles, the filmmaker and a mother of three from California. "And by expecting kids to work a ’second shift’ in what should be their downtime, the presence of schoolwork at home is negatively affecting the health of our young people and the quality of family time. "

So teachers at Mango Elementary School in Fontana, Calif., are replacing homework with "goal work" that is specific to individual student’s needs and that can be completed in class or at home at his or her own pace. The Brooklyn School of Inquiry, a gifted and talented program, has made homework optional. "I think people confuse homework with rigor," said Donna Taylor, the Brooklyn School’s principal, who views homework for children under 11 as primarily benefiting parents by helping them feel connected to the classroom.

Research has long suggested that homework in small doses can reinforce basic skills and help young children develop study habits, but that there are diminishing returns. Still, efforts to roll back homework have been opposed by those who counter that there is not enough time in the school day to cover required topics and that homework reinforces classroom learning. In Coronado, Calif. , the school board rejected a proposal by the superintendent to eliminate homework on weekends and holidays after some parents said that was when they had time to help their children and others worried it would result in more homework on weeknights.

Homework wars have divided communities for over a century. In the 1950s, the Sputnik launching ushered in heavier workloads for American students in the race to keep up with the Soviet Union. The 1983 report "A Nation at Risk" and, more recently, the testing pressures of the No Child Left Behind law, also resulted in more homework for children at younger ages. A few public and private schools have renounced homework in recent years, but most have sought a middle ground. In Galloway, the policy would stipulate that homework cover only topics already addressed in class. Dr. Giaquinto, Galloway’s superintendent, said the goal of the proposed policy was to make homework "meaningful and manageable," noting that teachers would have to coordinate assignments so that a student’s total homework would not exceed the time limit.

A. most schools disapprove of testing and competition for college

B. homework can be done most efficiently by school students at night
