问题 综合

图6是我国东部中亚热带某地等高线地形图,某校高中学生夏令营在图示区域进行了野外天文、地质、植被、聚落等综合考察活动。读图回答下列问题。(36分)

(1)同学们沿图中登山线路行进时,观察到沿途植被垂直变化不大。你认为主要原因是什么?

(2)若考察小组在D处突遇泥石流,①②③四条逃生线路中最佳的是;简要说明你选择的理由。(4分)

(3)同学们把夜晚宿营地点选在图中A处,从图中提供的信息简述理由。(4分)

(4)某同学建议在图中C处建一火情嘹望台,你认为此建议可采纳吗?____________。为什么?

若用现代化的手段动态监测山林火灾,最好采用_______________技术。(6分)

(5)从图中提供的信息简述城镇B兴起的主要区位条件。(6分)

(6)沿登山路线是否适合开垦梯田?简要说明理由。(4分)

该地位于中亚热带,过去以单一粮食生产为主,大量秸秆用作生活燃料。现在通过发展沼气,增加多层多级利用,农业生态系统走向良性发展。

(7)读图7分析在当地农村推广使用沼气产生的效益。(10分)

答案

(1)(共2分)沿线相对高度不够大,水热状况垂直分异不显著

(2)(共4分)②远离山谷且海拔较高

(3)(共4分)地势较高,夏季相对凉爽(2分 )、位于鞍部,地形相对平坦开阔

(4)(共6分)不宜采纳;不能通视该山各个地点;遥感(RS技术)

(5)(共6分)位于开阔的谷地,地势平坦;靠近河流,可获得水源;有便利的水运条件

(6)(共4分)可以;(坡度大于 的山地,从生态角度考虑,不宜发展种植业)

通过计算,登山路线的坡度仅儿度(不到 ),说明坡度缓,可以辟为梯田。

(7)(共l0分)

(经济效益)提供沼肥、沼液、沼渣,有利于农业多种经营(农林牧渔的发展),增加收入:

(社会效益)解决农村生活用能,节约能源

(生态效益):沼气利用(是清洁能源)可减少农村大气污染物排放 :减少砍伐林木、薪柴,改善生态环境(涵养水源,保持水土):沼渣液可还田,增加土壤有机质:;地处中亚热带,发展沼气原料丰富,且全年可利用沼气(或沼气利用时间长)

A few years ago I had an "aha!" moment regarding handwriting.

I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task. It occurred at first that I did not recognize the handwriting, and then I realized whose it must be. I finally became aware of the fact that I had been working with this colleague for at least a year, maybe two, and yet I did not recognize her handwriting at that point.

It was a very important event in the computerization of life—a sign that the informal. Friendly communication of people working together in an office had changed from notes in pen to instant messages and emails. There was a time when our workdays were filled with little letters, and we recognized one another’s handwriting the way we knew voices or faces.

As a child visiting my father’s office, I was pleased to recognize, in little notes on the desks of his staff, the same handwriting I would see at home in the notes he would leave on the fridge—except that those notes were signed "dad" instead of "RFW".

All this has been on my mind because of the talk about The Rise and Fall of Handwriting, a book by Florey. Sire shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well, but many others argue that people in a digital age can’t be expected to learn to hold a pen.

I don’t buy it. I don’t want to see anyone cut off from the expressive, personal associations that a pen still promotes better than a digital keyboard does. For many a biographer, part of really getting to know their subjects is learning to read their handwriting.

What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16th century Italy. That may sound impossibly grand—as if they want kids to learn to draw by copying classical paintings. However, they have worked in many school systems.

People working together in an office used to().

A.talk more about handwriting

B.take more notes on workdays

C.know better one another’s handwriting

D.communicate better with one another
