题目

下列说法符合可持续发展观点的是A．陡坡开荒B．围湖造田C．不准开荒D．在某水域的一定时间内实行“休渔”制度 答案：D解析:本题主要考查的是可持续发展的相关知识。可持续发展指既满足当代人的需求，又不损害后代人满足其需求的能力，在某水域的一定时间内实行“休渔”制度可以使鱼类得到繁衍，而陡坡开荒、围湖造田会导致生态环境的破坏，不准开荒是做不到的也是不合理的，应该在适合地带合理开荒。句型转换1.My parents were repairing the computer at this time yesterday.(对画线部分提问)_______ _______ your parents doing at this time yesterday?2.The wall around this city is 13.7 kilometers long.(对画线部分提问)_______ _______ is the wall around the city?3.It took them about five hours to finish the work.(改为一般疑问句)_______ it _______ them about five hours to finish the work?4.I think this story is the funniest of all the stories.(同义句转换)I think this story is _______ _______ any other story.5.Grandma Zhou enjoys the life in the countryside because it is much cleaner there.
