题目:

论述农业生态学的主要任务及其发展趋势。

答案:

参考答案:

人类社会的发展在一定程度上必然要以牺牲自然资源为代价,如何尽可能减轻经济发展对生态环境的压力和降低资源成本,走可持续发展之路,是生态学面临的重大问题。同样,这也是农业生态学要探索的问题。把握农业生产的生态一技术一经济复合系统的相互作用关系与特点,从整体结构优化和提高系统功能上进行合理调控,以促进农业生产持续高效发展,是农业生态学未来发展中面临的重要任务。

随着人类社会的不断发展,人口持续增长和对产品需求的不断提高,全球性的资源和生态环境问题日趋严重,并已引起国际社会的高度重视。如何协调人类社会经济发展与生态保护的矛盾,已逐步成为可持续发展的焦点问题。作为直接以生物和自然资源环境进行再生产的农业,其可持续发展问题显得更为重要,而以研究农业生态系统生物与环境关系的农业生态学,也必将随之受到更普遍的重视。进入21世纪,我国农业将全面步入发展新阶段,农业生产和农村经济结构调整优化,农业生产由数量型向质量型发展,农业增长方式由粗放型经营向集约型经营转变。尤其面临WTO带来的机遇与挑战,有效解决产量与品质、增产与增收的矛盾,提高农业效益和增强国际市场竞争力等已是新阶段农业的迫切任务。在这种背景下,有效解决日趋严重的资源与环境问题意义更为重大,因此,在我国农业由传统农业向现代农业发展进程中,农业生态学的研究和应用也将越来越活跃,其学科地位和作用将更加突出。

61.                         
It is possible to be an attractive person when you are in a job interview or in a place where you just want to gain the respect of others. It’s not about how much money you make, and it’s not about your daddy is. What it is about is some simple things in your life. It just has a lot to do with being confident in who you are.
62.                       
Ask questions about others when you stay with them and listen to them patiently. Talking about yourself all the time shows that you pay no attention to others. Shifting attention from yourself to others makes you attractive. It indicates that you are humble (谦逊的). If you come across as a know-it-all (even if you really do know it all), it really pushes people feel that you care, you are humble and you can be trusted.

Have you ever seen a potentially very attractive person, but he has terrible posture (姿势)?It’s all ruined, isn’t it? Or perhaps you have seen someone who may be quite ugly but he has great posture and so suddenly he is really attractive? It’s true. Your posture says a lot about you – it says whether you have confidence, or simply if you really care. Talking physically, it is one of the most important physical characteristics you need.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
64.                        
Keeping doing things shows that you have power. You’re told to stay busy to ward off (防止,避免) depression and feelings of anxiety. But did you know you should also stay busy to be really attractive? It’s true. Always have something to do. Have you ever seen someone just sitting around, doing nothing? How unattractive! Always be busy with something, Even if for some reason you have to make something up.                                                                                                                                                                                                                                                                                                                                                                                                            
65.                          
Wear clothes that fit you. Too tight, people are distracted. Too loose, you just look sloppy (肥大而难看的). For women, wearing tight pants or shirts is not attractive. Slightly loose things are best, or other things that just fit you and your shape well but not tight. Men and women with taste and style really don’t know why some guys think their pants sagging down are somehow attractive. It just tells people you don’t really care. You are following the crowd. Wear things that fit you nicely.
