近三十年中国发生过哪些重大的灾害

In the course of nearly 30-year clinical nursing, I have encountered various puzzles and dilemmas, which made me uneasy and depressed when doing my job and even force me to address an overall perception of the essence and development of modern nursing. Consequently, I addressed brief analyses of the restrictions on the development of nursing at a surface level. In this way, I released my sadness and depress down in my heart since employed, and solved problems about my career and life value. This also made me more responsible for the development of nursing. In order to help out my colleagues in the upset state the same as mine, I propose the following ideas on the fundamental issues of restrictions on nursing’s development, and I would appreciate for the exchange with your honored experts.

2.雹灾打烂了庄稼,摧毁了农人丰收的希望,但父亲仍然“对着麦子微笑”,这表明父亲是一个慈爱、乐观、坚强,并且能从容、镇定、坦然地面对困难的人.作者对麦子念念不忘,是对父亲的这种精神的念念不忘与继承.生活中难免会遇到困难、挫折和不幸,但我们要敢于面对,也要勇于面对,并且要勇敢地跨越沮丧的心灵世界,要坚信,只要拥有希望的种子,有勇于战胜困难的决心和乐观的心态,我们的理想就会结出丰硕的果实.

本题考查我国的区域地理和农业生产。第(1)题，根据表中的信息可得，耕地、荒地比例减小，林地、草地比例增大，可以得到生态变好的原因；生态变好有利于河流涵养水源、保持水土。第(2)题，过度发展种植业势必减少林地和草地，从而导致水土流失加重，化肥、农药的使用带来了严重的土壤和水源污染。
