An Earthship is a home that is built of materials such as old tires and aluminum cans. It is the idea of a man named Michael Reynolds. Many Earthships are more or less self-sufficient because they provide their own heat, air and water. They often have gardens watered and fed by wastewater. They are comfortable and ecologically friendly.
The main materials used in building Earthship is tires. Tires are plentiful and can’t be recycled like paper, plastic and metal. While building supplies for most houses can be very expensive, old used tires are free. First, the tires are packed tightly with dirt. Each full tire weighs as much as 400 pounds. The tires are then loaded like bricks. The walls are extremely strong. They also help keep a leveled temperature in the house (between 60 and 70 degrees) without heating and cooling systems.
The walls inside the Earthship are made of aluminum cans that are held together by cement. Then they are coated with adobe (专坯) or stucco (灰墁).
The roofs of Earthship are sloped so that rain and snow run into large tanks. These tanks hold all the water for the house, and pumps push the water through the pipes. Sometimes, water flows in certain areas of the house as waterfalls! Water that has been used is pumped out into the gardens where owners grow much of their own food.
In most of these houses, the southern side has huge windows that take in winter sunlight as a source of heat. Summer sun does not come in through the south windows, so it doesn’t get too hot in the summer. The house also has solar panels(太阳板) that gather energy for lights and hot water and cooking. The Earthship have all the comforts of a regular house without the high cost of electric bills!
In a time when we are running out of energy resources, pollution is bad, and waste is piling up, Earthships are the best places to live in. For people who truly care about the environment, Earthship provides a great alternative to traditional houses. You won’t be giving up any comforts, and the styles are attractive. We all hope that more and more people will build Earthships and take a huge step toward helping the environment and saving our planet.

某研究性学习小组用如图（a）所示装置验证机械能守恒定律。让一个摆球由静止开始从A位置摆到B位置，若不考虑空气阻力，小球的机械能应该守恒，即
，但直接测量摆球到达B点的速度v比较困难，现利用平抛的特性来间接地测出v。如图（a）中，悬点正下方一竖直立柱上 放置一个与摆球完全相同的小球（OB等于摆线长），当悬线摆至B处，摆球与小球发生完全弹性碰撞（速度互换），被碰小球由于惯性向前飞出作平抛运动。在地面上放上白纸，上面覆盖着复写纸，当小球落在复写纸上时，会在下面白纸上留下痕迹。用重锤线确定出A、B点的投影点N、M。重复实验10次（小球每一次都从同一点由静止释放），球的落点痕迹如图（b）所示，图中米尺水平放置，零刻度线与M点对齐。用米尺量出AN的高度h1、BM的高度h2，算出A、B两点的竖直距离，再量出M、C之间的距离x，即可验证机械能守恒定律。（已知重力加速度为g，两球的质量均为m。）
（1）根据图（b）可以确定小球平抛时的水平射程为 m。
（2）用题中所给字母表示出小球平抛时的初速度v0 = 。
（3）此实验中，小球从A到B过程重力势能的减少量ΔEP = ，动能的增加量EK= ，
若要验证此过程中摆球的机械能守恒，实验数据应满足一个怎样的关系式 。（用题中的符号表示）

In college, Spring Break （春假）is usually associated with the beach, parties and sleepless nights, bringing about relaxation, free time and friends. Students who wish to spend their break doing something productive and rewarding, however, may choose to participate in the Alternative Break Program. It places college students in communities both at home and abroad.
The Program allows students to take part in various projects dealing with issues such as literacy （识字）, homelessness and the environment. It includes helping kids with their lessons, raising money for families in need and collecting data for environmental research.
The hope is that, by getting themselves involved in different environments, students will have the opportunity to learn about members of communities and broaden their view. In turn, they will incorporate (融合) their experiences and lessons learned into their own communities. In a word, the Program aims to encourage students to be active citizens nd engage themselves in making a difference in society.
In the spring of 2006, about 36,000 students in the USA participated in the Alternative Break Program.
Samantha Giacobozzi, now director of the Program, has been on five alternative break trips herself, including trips to New Orleans, India and Dominican Republic. “I was a student who went on alternative break trips and had my life totally transformed by that experience,” she said. “Every year, we meet many students who have attended the Program. You can see changes in their life that are connected with their alternative break experiences.”
The Program began in 1991, Today, it has become increasingly popular with college students in the United States.
56．Who may choose to participate in the Alternative Break Program?
A．College students who want to work in communities.
B．College students who want to have a good time on the beach.
C．College students who wish to do something productive and rewarding.
D．College students who want to bring about relaxation, free time and friends.
57．The aim of the Program is to .
A．allow students to take part in various projects
B．help students to raise money for families in need
C．encourage students to be active and make a difference in society
D．teach students to collect date for environmental research
