阅读材料,回答问题。 苏霍姆林斯基曾说:“要使学校的每一面墙壁说话,发挥出人们期望的教育功能。”我们的校园,不仅使每一面墙壁会说话,还使每一寸土地、每一株花草树木、一切教学、生活设施都会说话。 我校四年级三班学生墙报上的一首小诗较详细地记载了我们校园环境的育人功能。这首诗(节选)是这样定的: 《校园处处会说话》 …… 在校门外,远远地, 就会望见公寓楼上耀眼的校训: “做有中国灵魂,有世界眼光的人” 它时刻鞭策我们不忘重任。 …… 步入聚厅, 正面墙上“为了建设祖国,吃好营养配餐”的警句使我们改掉了挑食的毛病。 向南望去,墙壁老师又会对你说:“农民伯伯,炊事员叔叔多辛苦呀,我们绝不浪费粮食。” 记住了!我们就是这样做的。 问题:结合所学的教育学知识,谈谈你对学校教育环境的看法。
Fueled by weather, wind, and dry undergrowth, uncontrolled wildfires can burn acres of land-and consume everything in their way-in mere minutes. 31, more than 100,000 wildfires clear 4 million to 5 million acres of land in the U.S. every year. A wildfire moves at speeds of up to 23 kilometers an hour, consuming everything-trees, bushes, homes, even humans-in its 32. There are three conditions that need to be 33 in order for a wildfire to burn: fuel, oxygen, and a heat source. Fuel is any material 34 a fire that will burn quickly and easily, including trees, grasses, bushes, even homes. Air supplies the oxygen a fire 35 to burn. Heat sources help spark the wildfire and bring fuel to 36 hot enough to start burning. Lightning, burning campfires or cigarettes, hot winds, and even the sun can all provide 37 heat to spark a wildfire. 38 often harmful and destructive to humans, naturally occurring wildfires play a positive role in nature. They 39 nutrients to the soil by burning dead or decaying matter. They remove diseased plants and harmful insects from a forest ecosystem (生态系统). And by burning 40 thick tress and bushes, wildfires allow sunlight to reach the forest floor, enabling a new generation of young plants to grow.
Questions 21-25 are based on the following passage: In computing, passwords are commonly used to limit access to official users. Yet the widespread use of passwords has serious drawbacks. Office workers now have to remember an average of twelve system passwords. In theory they should use different passwords for each site, but in reality these would be impossible to remember, so many people use the same password for all. An additional problem is that the majority use simple words such as “hello”, or names of family members, instead of more secure combinations of numbers and letters, such as 6ANV76Y. This permits computer hackers to download dictionaries and quickly find the word that allows them access. When system users forget their passwords there is extra expense in supplying new ones, while if people are forced to change passwords frequently they often write them down, making systems even less secure. Therefore, it is clear that the idea of passwords. Which have been used as security devices for thousands of years, may need rethinking. One possible alternative has been developed by the American firm Real User, and is called “Passfaces”. In order to access the system a worker has to select a series of photographs of faces from a randomly (随机地) generated sequence. If the pictures are selected in the correct order, access is granted. This concept depends on the human ability to recognize and remember a huge number of different faces, and the advantage is that such a sequence cannot be told to anyone or written down, so is more secure. It is claimed that the picture sequence, which used photographs of university students, is easier to remember than passwords, and it has now been adopted for the United States Senate. What does the author think of the password
A. It is an old system that needs improvement.
B. It provides as much security as before.
C. It should be abandoned by computer users.
D. It has developed to an advanced stage.
